Entry, Patio & Storm Door Options

The right replacement depends on the opening, the way you use it, and the appearance you want for your home. We’ll discuss your preferences, budget, existing exterior, and available product choices before moving into the design stage.

During the design stage, we can review samples or examples from past projects. Your door is then engineered and manufactured according to the approved design and measurements. Available materials, glass, finishes, and hardware depend on the product selected.

Our Door Installation Process

Each project starts with a free in-home consultation. We discuss what you want to change, review your budget and preferences, and measure the opening for the proposed replacement door.

An exterior door assessment may consider the slab, frame, threshold, trim, hardware, and surrounding opening. After installation, we check that the door operates, closes, latches, and seals as intended. Project timing varies according to the selected door and the conditions at the home.

Lifetime Warranty Coverage for Products & Labor

Coverage can vary by the specific door product, so homeowners should review the written terms before approving a project. We recommend confirming applicable coverage, exclusions, transfer provisions, and the process for requesting future service.
