FAQs

General

  • What products does Castle Windows install?

    We install replacement windows, entry and patio doors, siding, and roofing. Every project starts with a free, in-home consultation so you know exactly what's being installed before any work begins.

  • Is the estimate really free?

    Yes. We provide a free, no-obligation quote for windows, doors, siding, or roofing, with no pressure to commit on the spot. You can request one anytime through our free quote form.

     

  • What are Castle's windows made of?

    Our windows are built with virgin vinyl, not the recycled or reprocessed vinyl used by many competitors. Virgin vinyl holds its color and structural strength much longer, which is part of how we're able to back it with a true lifetime warranty.

  • What does the lifetime warranty actually cover?

    Our warranty covers leaks and drafts, vinyl, color, glass, seals, parts, screens, and window operation for as long as you own your home, with no pro-rating. You can see the full warranty comparison to see how it stacks up against other companies.

  • Does the window warranty cover installation, or just the product?

    Both. A lot of warranties in this industry exclude installation entirely, which leaves homeowners stuck between the manufacturer and the installer if something goes wrong. Ours covers installation and includes free labor on all service calls.

  • Does Castle Windows offer financing?

    Yes, we offer financing options through local and regional banks, including 100% financing with no down payment for qualified buyers. We also accept Visa, Mastercard, Discover, and American Express. Our team can walk you through what applies to your project during your free estimate.

  • How long has Castle Windows been in business?

    We've been family-owned and operated since 1977. We're consistently ranked among the largest home improvement companies in the country, and we've outlasted the majority of the competitors we started alongside decades ago.

  • How do I request service on windows I already have?

    If you need a repair or service visit, you can submit a request through our service page or call us directly. Service calls are free, since all labor is included under our lifetime warranty.

  • Is Castle Windows licensed and insured?

    Yes. We hold active licenses and registrations in every state where we operate. We are also available by phone anytime, day or night, if you have questions before or after your project.

Mechanicsburg Custom Door Installation

Mechanicsburg Clad Window Installation

  • How much does clad window installation cost in Mechanicsburg?

    Cost depends on the number and size of the windows, cladding material, operating style, glass selection, custom configuration, and condition of each opening. Bay windows and combination units may require different measurements and installation work than standard replacement windows. We offer free estimates so you can receive project-specific pricing.

  • How long does clad window installation take?

    The schedule depends on the number of windows, project complexity, custom configurations, opening conditions, and any preparation required before installation. A custom bay or combination unit may involve different installation considerations than a standard window. We evaluate the project before providing scheduling expectations.

  • Are clad windows a good choice for older homes?

    Clad windows can suit older homes when their proportions, interior finish, exterior appearance, and operating style complement the property. The existing opening and surrounding materials should be evaluated before choosing a replacement configuration. Compatibility depends on the home and project rather than its age alone.

Cedar Grove Siding Installation

  • Should damaged siding be repaired or fully replaced?

    The answer depends on the extent of the damage and the condition underneath. Localized damage may be repairable when matching material is available and the underlying wall remains sound. Replacement may be appropriate when damage is widespread, matching is difficult, moisture problems recur, or the existing exterior no longer meets your goals.

Fredericksburg Siding Installation

  • What are common reasons to replace home siding?

    Homeowners often consider siding replacement because of visible damage, deterioration, moisture concerns, difficult maintenance, or an outdated appearance. Replacement can also be part of a broader plan to change the home’s exterior design. The underlying cause and condition should be evaluated before selecting a new siding system.

  • Does your team offer free siding estimates?

    Yes. At Castle Windows, we offer free estimates for residential siding projects.

  • How long does siding installation take?

  • How much does siding installation cost in Mt. Laurel?

    Cost depends on the home’s size and layout, existing siding condition, selected material, preparation requirements, and total project scope. Because those variables differ by property, a project-specific estimate is more useful than a general price range.

  • How long does siding installation take?

    Project duration can vary based on home size, design complexity, weather, material availability, removal requirements, and conditions discovered during preparation. Ask the installer for a timeline based on the written scope for your property.

East Berlin Siding Installation

East Berlin Roofing

  • How do I know whether my East Berlin home needs roof repair or replacement?

    A repair may be appropriate when a problem is limited and identifiable. Replacement may be considered when age, widespread deterioration, recurring leaks, or extensive damage affects the roofing system. A qualified roofing professional should evaluate the roof before recommending either option.

  • What should I ask before hiring a roofing contractor in East Berlin?

    Ask for proof of the contractor’s Home Improvement Contractor (HIC) registration number and insurance. Pennsylvania requires contractors performing residential home improvement work to register with the Attorney General’s Office, so confirming that registration is a reasonable first step.

    Please contact us to confirm current estimate availability for roofing projects in East Berlin. Our team can discuss your home and the work you’re considering, then explain the next step.

  • What roofing materials are available for homes in East Berlin?

    Residential roofing materials can include asphalt shingles, metal, slate, tile, and other systems. Suitable options depend on the home’s structure, roof design, local conditions, budget, and the contractor’s current offerings. Contact us to confirm which roofing materials we offer for your project.

  • How long does a residential roof replacement take?

    Project duration depends on the roof’s size and complexity, selected materials, weather, tear-off requirements, necessary decking repairs, and crew scheduling. Ask for a project-specific schedule after the scope and existing roof conditions have been reviewed.

Mt. Laurel Window Installation

  • What signs indicate that my home may need replacement windows?

    Common signs include drafts, leaks, condensation between panes, damaged frames, difficult operation, visible deterioration, or windows that no longer close or lock properly. The condition of the opening and the extent of the damage help determine whether replacement should be considered.

  • What window styles can I consider for a replacement project?

    Common replacement-window styles include double-hung, casement, slider, awning, picture, bay, bow, and garden windows. A suitable style depends on the opening, ventilation needs, desired appearance, access, and overall project requirements. Contact us to discuss which options are currently available.

  • How should I prepare for a window installation estimate?

    Identify any drafty, damaged, leaking, or difficult-to-operate windows. It’s also helpful to note preferred operating styles, appearance goals, and whether you’re evaluating one window or a larger replacement project. We offer free estimates for windows.

    During your estimate, you can discuss entry, front, exterior, patio, French, sliding, and storm doors. Confirm availability with our team.

Mechanicsburg Casement Window Installation

  • What are casement windows?

    Casement windows are hinged at the side and open outward, usually with a crank or operator handle. Their design can provide a broad, unobstructed glass area and substantial ventilation when the sash is open.

Mechanicsburg Bay Bow Window Installation

  • Can a bay or bow window replace another type of window?

    It may be possible, but compatibility depends on the existing wall, opening, structural support, and selected window design.

Mechanicsburg Slider Window Installation

  • How do I know if my existing windows need replacement?

East Berlin Window & Door Installation

  • How do I know whether my windows need replacement?

    Drafts, failed insulated-glass seals, visible deterioration, moisture concerns, difficult operation, or an outdated appearance can justify an evaluation. A professional assessment can help determine whether the issue calls for replacement or may be addressed through maintenance or repair.

  • What should I prepare before requesting a window or door estimate?

    Photos and information about the home’s age or previous replacements may provide helpful project context.

Mechanicsburg Awning Window Installation

  • How much does awning window installation cost?

    Cost depends on the window size, number of openings, selected materials and features, removal requirements, and installation conditions. A project-specific consultation and estimate can account for the dimensions and condition of each opening rather than relying on a general price.

  • Can awning windows be opened when it’s raining?

    Because an awning window is hinged at the top and opens outward from the bottom, its sash can deflect light rain away from the opening. Wind, rain intensity, window placement, and the specific opening conditions should be considered before leaving any window open.

  • What does your TRUE Lifetime Warranty cover?

    Our TRUE Lifetime Warranty covers leaks and drafts, vinyl, color, glass, seals, parts, screens, window operation, and installation labor. The warranty isn’t prorated, includes free lifetime service labor for covered warranty requests, and transfers to a new owner at no charge.

Fredericksburg Window Installation

  • How do I know whether my windows should be repaired or replaced?

    Repair may be appropriate when the frame and opening remain sound and the problem is limited to hardware, weatherstripping, glazing, or another serviceable component. An assessment can help clarify the condition of the window and surrounding opening.

    We offer steel and fiberglass doors. These materials differ in construction, appearance, maintenance considerations, and performance characteristics. We can review the currently available options during your consultation.

Mechanicsburg Roofing

  • What roofing services does your team provide?

    We provide residential roofing, specifically roof replacement. Because the exact scope depends on the property and project, contact us to confirm whether we can address a requested repair, inspection, storm-related concern, or other roofing need.

  • What warranty protection should I ask about when replacing a roof?

    Ask about material coverage, installation defects, service labor, exclusions, maintenance requirements, pro-rating, and transfer to a new owner. Our published warranty comparison addresses installation labor, free lifetime service labor, and non-pro-rated coverage. Confirm with us which Lifetime Warranty provisions apply specifically to your roofing project before approving the work.

  • What roofing problems can follow a storm?

    Wind, hail, falling branches, and heavy weather can damage shingles, flashing, vents, gutters, and underlying roof components. Some damage isn’t visible from the ground, so a professional assessment may be appropriate after a significant storm or when leaks and other warning signs appear.

Fredericksburg Door Installation

  • How do I know whether my door needs replacement?

    Sticking, drafts, leaks, visible damage, or difficulty locking can indicate that your door needs attention. An assessment can determine whether the issue involves the door unit, hardware, frame, or surrounding opening.

  • Can a replacement door improve security?

    A properly fitted replacement door can support entry security when combined with a sound frame, functioning lockset, secure hardware, and correct installation. Security depends on the complete door system rather than the door panel alone.

    Door selection can account for architectural style, color, and existing sightlines. The choices available depend on the product line, required dimensions, and configuration offered for your project.

Bilco Doors

  • What is a Bilco basement door?

    A Bilco basement door is an exterior bulkhead-style door that connects an outdoor areaway with a basement entrance. It typically opens upward to provide wider access than a standard entry door. Homeowners may use it to reach storage or finished basement space or to move large items.

  • What can cause a Bilco basement door to leak?

    Possible causes include gaps around the frame, deteriorated sealant, damaged door components, drainage problems, or water collecting near the areaway and foundation. Because several conditions can produce similar symptoms, visible water doesn’t always mean the door itself is the only source.

Siding

  • How much does siding replacement cost?

    Siding replacement pricing depends on the proposed scope for your home. Cost factors can include dimensions, material and profile choices, preparation, removal, trim, soffit, fascia, access, and concealed conditions.

  • Do you offer free estimates for custom doors?

    Yes. Contact us to discuss your existing entry and project goals.

  • How long does a custom door project take?

    Timing varies according to the door’s specifications, manufacturing requirements, product availability, opening conditions, permitting needs, and installation scope. A project-specific estimate is necessary because there isn’t one reliable timeline for every custom door.

Home Improvement FAQs

  • What should I consider before replacing my windows?

    Consider drafts, condensation, visible frame or glass damage, difficulty opening or locking windows, outside noise, maintenance needs, and window age. These signs don’t always require replacement. Window style, frame material, glass construction, installation method, warranty coverage, and budget can also affect your decision.

Roofing

  • Does your team replace residential roofs?

    Yes. We provide residential roof replacement as part of our home improvement services.

  • What roofing materials do you offer?

    We can identify the roofing options currently available for your home when you request a quote. Ask us for manufacturer specifications and applicable warranty documents.

  • What’s included in a roofing estimate?

    Your estimate should identify the existing roof condition, removal or overlay scope, proposed materials, installation details, property preparation, cleanup, warranty terms, and how scope changes will be handled.

  • What warranty coverage is available for roofing?

    Roofing protection may include separate manufacturer and workmanship warranties. Review the applicable terms for your project, including duration, exclusions, labor provisions, registration requirements, and claim procedures.

  • How long does residential roof replacement take?

Andersen Windows

  • Does your team install Andersen replacement windows?

    Contact us to confirm whether Andersen replacement windows are currently available for your project and whether we hold an applicable Andersen dealer or Certified Contractor status.

  • How much do Andersen replacement windows cost?

    Pricing depends on the product series, material, size, operating style, glass, customization, installation conditions, and number of windows. A project-specific estimate is necessary because those variables can substantially change the total cost.

  • What is covered by the Andersen window warranty?

    Coverage varies by product line. Andersen states that many non-coastal products include 20 years of coverage for standard glass and 10 years for non-glass components. Certified installations may have a separate two-year installation warranty. Review the warranty document for the specific product and installation arrangement rather than assuming one term applies to every Andersen window.

Bay & Bow Windows

  • What is the difference between a bay window and a bow window?

    A bay window generally uses angled sections that project from the wall. A bow window typically creates a broader, more continuous curve using multiple window units. The appropriate style depends on the home’s architecture, existing opening, desired projection, and design goals.

Double-Hung Windows

  • What is the difference between double-hung and single-hung windows?

    Both styles have vertically arranged sashes. A double-hung window allows both the upper and lower sashes to move, while a single-hung window typically has only one movable sash. The appropriate choice depends on ventilation preferences, cleaning access, design, budget, and the existing opening.

  • Can replacement double-hung windows fit existing window openings?

    Replacement windows are commonly selected to fit existing openings, but fit depends on accurate field measurements, frame condition, and the home’s construction. A professional assessment is needed to determine the appropriate product configuration and installation method.

  • What should I check before replacing double-hung windows?

    Check for drafts, condensation between glass panes, difficult operation, damaged frames, visible moisture, deteriorated seals, and glass failure. The condition of the frame and surrounding opening should also be evaluated before selecting a replacement method.

  • How long does double-hung window replacement take?

    Project duration varies based on the number of windows, accessibility, existing opening conditions, weather, finishing needs, and installation method. The installer should provide an expected schedule after assessing the home and confirming the project scope.

Mid-Atlantic Raynor Garage Doors

  • Does Raynor provide a residential garage door warranty?

    Raynor warranty coverage varies by product, component, purchaser, property type, and installation circumstances. Review the manufacturer’s written warranty for the exact product selected. Also confirm whether the installer provides separate coverage for labor or installation-related concerns, since manufacturer and installer responsibilities aren’t necessarily the same.

Locations

  • Are Castle Windows locations independently operated?

    We can’t confirm from the available information whether individual locations are independently operated or managed through one corporate structure. Contact us directly if the operating structure or responsibility for service in your area affects your project or warranty request.

Awning Windows

  • How do awning windows compare with casement windows?

    Both styles open outward, but awning windows are hinged at the top while casement windows are hinged at the side. The better fit depends on the opening, preferred ventilation direction, privacy needs, exterior clearance, and how you want to operate the window.

  • How much do replacement awning windows cost?

    Pricing varies based on the opening size, number of windows, installation conditions, selected materials and features, and overall project complexity. Because no single price applies to every home, an on-site estimate is needed to provide an accurate project cost.

All-Wood Windows

  • Are all-wood windows a good choice for an older or historic home?

    They can be a good architectural fit where natural materials, traditional proportions, and existing trim are important. The project may also require attention to sash dimensions, decorative details, opening condition, and local preservation requirements. A consultation can help determine whether repair, an insert window, or full-frame replacement better fits the home and project goals.

  • How much maintenance do all-wood windows require?

    Exterior wood generally requires periodic inspection and protective maintenance. Watch for moisture exposure, peeling or failed finishes, ultraviolet damage, drainage problems, and early deterioration. The necessary frequency depends on the finish, climate, installation details, exterior exposure, and condition of the surrounding trim.

  • Can your team install replacement windows in existing openings?

    We install residential replacement windows in existing openings. During the consultation, we can determine whether the project calls for an insert, sash replacement, or full-frame approach.

Careers

  • Is installation work available year-round?

    Yes. Our installation crews work year-round. Ask about shifts, employment classifications, and seasonal workloads for a specific position.
