Residential Window & Door Installation in Fort Collins
A-1 installs replacement windows, entry doors, interior doors, and patio and sliding doors for Fort Collins homes. We help homeowners choose the right installation approach for the existing opening and complete the work with careful fitting, sealing, hardware installation, and finish details.
When a door sticks, drags, will not latch, or no longer closes correctly, replacement is not always the first answer. A-1 can inspect the door, frame, hinges, threshold, weather seals, and hardware to determine whether an adjustment or repair can restore reliable operation.

A-1 installs and repairs commercial doors, hollow metal doors and frames, and door hardware for Fort Collins businesses, facilities, and commercial properties. Our work includes hinges, door closers, exit hardware, thresholds, weather seals, latching hardware, and related components that affect how a commercial door operates.
For existing doors, we diagnose problems such as dragging, binding, slamming, poor alignment, damaged frames, and doors that will not close or latch correctly. For new and replacement openings, A-1 installs the physical door, frame, and hardware and can install or mount door-side access-control hardware when it is part of the project.
