Door Installation & Replacement in Charlotte, NC

Published July 2, 2026  ·  Keyway Construction & Roofing

A door is one of those things you stop noticing until it stops working right. It sticks in humidity, drafts in winter, will not lock cleanly, or the frame around it has quietly rotted. And because the exterior doors on a Charlotte home take sun, storms, and daily use year after year, they wear out faster than most people expect. When it is time to replace one, the install matters as much as the door itself, because a door set wrong leaks air, water, and security.

Keyway Construction & Roofing installs and replaces exterior and interior doors across the Charlotte metro. As a licensed general contractor, we do the part that trips up a lot of installers: when we pull an old door and find rotted framing behind it, we repair it in the same visit instead of setting a new door over bad structure. Here is what we install and how we do it right.

Door Types We Install in Charlotte

Entry and front doors. The front door sets the tone for the whole house and takes the most weather and use. We install steel, fiberglass, and wood entry doors, with fiberglass being a favorite in Charlotte for standing up to heat and humidity without warping.

Exterior and back doors. Side, back, and utility doors get less attention but wear the same way, and a failing seal here is a common source of drafts and water intrusion.

Patio and sliding doors. Sliding glass and French patio doors bring in light and connect indoor and outdoor space, but their larger openings and hardware demand precise installation to seal and operate correctly for years.

Storm doors. A storm door adds a layer of weather protection and ventilation in front of your main entry, extending the life of the door behind it.

Interior doors. Bedroom, closet, and bathroom doors that stick, sag, or no longer latch are a common part of a repair or renovation punch list, and often come up alongside our handyman services.

Signs It’s Time to Replace a Door

Doors tell you when they are done. Watch for daylight visible around the frame when the door is closed, a door that sticks or drags in humid months, drafts and rising energy bills, difficulty locking or a door that no longer sits square, visible rot or soft spots in the door or frame, and condensation or fogging between the panes of a glass door. Any of these means the door has stopped doing its job of sealing the house.

Why the Frame Behind the Door Matters

Here is the part budget installers skip. When an exterior door has been leaking air or water, the framing and threshold around it are often rotted, and Charlotte’s humidity accelerates that. Setting a brand-new door into rotted framing guarantees the new one fails too, because it has nothing sound to seal against. As a licensed general contractor, Keyway handles that wood rot repair as part of the job, including sill and threshold repair, so the new door seals to solid structure. It is the difference between a door that lasts and one that drafts again in two years.

Doors, Windows, and the Whole Exterior

Doors rarely fail alone. The same weather and moisture that wear out a door work on the windows (in a range of window styles), the siding, and the trim around every opening. Because we handle the full exterior, we can address a failing door, aging windows, and any soffit, fascia, or trim rot as one coordinated project rather than sending you to three different contractors. If your windows are aging alongside the doors, our guide on window repair versus replacement is worth a look.

Our Door Installation Process

Every door starts with a free assessment and written estimate, where we measure the opening, check the surrounding framing, and recommend the right door for the location and your budget. We remove the old door and inspect the frame, repairing any rot or damage before the new unit goes in. The new door is set level, plumb, and square, then properly flashed and sealed against air and water. We finish with hardware, weatherstripping, and a walkthrough to confirm it operates and locks cleanly. Every install is backed by our 1-year workmanship warranty.
