Window & Door Installation in Alabama
A replacement window or exterior door is only as good as its installation. Improper installation — missing or incorrect flashing, inadequate shimming, air gaps, or failed sealant — causes water infiltration and air leakage that negates the product's energy performance and leads to costly moisture damage. Apex Architectural Metal installs replacement windows and exterior doors correctly throughout Birmingham, Huntsville, Gadsden, and across Alabama.
Replacement Window Installation
We install replacement windows in existing openings without disturbing the surrounding wall framing — the standard approach for renovations and upgrades. Our installation process includes:
- Removal of the existing window unit and inspection of the rough opening
- Repair of any rot or moisture damage in the rough opening framing
- Proper window flashing tape at the sill and sides before window insertion
- Correct shimming for plumb, level, and square alignment
- Insulation of the gap between the window frame and rough opening
- Interior and exterior trim installation and caulking
We select windows from quality manufacturers and help homeowners navigate the choices between frame materials (vinyl, fiberglass, aluminum-clad), glass packages (double-pane vs. triple-pane, low-E coatings, gas fills), and operating styles (double-hung, casement, awning, picture).
Exterior Door Installation
Exterior door installation involves the same attention to flashing and sealing that window installation requires, with the added complexity of hardware, threshold, and weatherstripping alignment for proper operation and seal. We install pre-hung door units — door, frame, and hinges assembled — and ensure the unit is plumb, level, and square before securing. Threshold and weatherstripping are adjusted for a proper seal against the Alabama climate.
We install:
- Entry doors (fiberglass and steel, single and double)
- Sliding patio doors and French doors
- Storm doors over existing entry doors
Why Proper Installation Matters
Alabama's climate — high humidity, frequent storms, and temperature extremes — is particularly unforgiving of poorly installed windows and doors. Flashing details that might survive for years in a dryer climate fail quickly here. We install to best practices, not minimum standards, because it protects our customers and our reputation.
