Sticking, sagging, drafting, or squeaking — whatever your door is doing wrong, we diagnose and fix it. From weatherstripping to door jamb repair to full replacement, we keep your doors working right.
Comprehensive Door Repair for Homes and Businesses
A door that doesn't work right is more than an annoyance. It wastes energy, compromises security, and can cause damage to the frame, floor, or wall over time. The good news is that most door problems are fixable — and far less expensive than full replacement.
We diagnose residential and light-commercial pedestrian doors throughout Northern Colorado, including entry doors, interior doors, and appropriate patio-door conditions. Whether the symptom involves hinges, jambs, thresholds, weather seals, hardware, or alignment, the first job is to find the root cause and confirm the repair scope.
Our repair services cover the full range of common door issues — from quick hardware swaps to frame rebuilding. And when a door is truly past repair, we'll tell you honestly and help you explore replacement options.
- Weatherstripping replacement and upgrades
- Door jamb repair and rebuilding
- Threshold and sill repair or replacement
- Hinge, lockset, and deadbolt service
- Frame realignment and shimming
- Sagging door correction
A Useful Repair Starts by Finding What Moved or Failed
The same symptom can have several causes. A latch that misses the strike may come from loose hinges, a sagging slab, seasonal movement, an out-of-square frame, or worn hardware. Repositioning the strike can hide the symptom without correcting the condition that caused it.
A-1's door-repair lane is pedestrian doors—not garage doors. The inspection follows the opening as a system: slab, hinges, frame and jamb, latch and lock alignment, threshold or sill, weather seals, surrounding movement, and evidence of water. That makes it easier to separate an adjustment from a component repair or full replacement.
- Note where the door rubs and whether the problem changes with weather
- Photograph the full opening, hinge side, latch side, threshold, and damaged area
- Do not force a door or keep tightening stripped screws without checking alignment
- Treat recurring water or rot as an opening problem, not just a caulk problem
Trying to Figure Out What's Wrong With Your Door?
Sticking, sagging, drafts, damaged jambs, worn thresholds, and latch problems often overlap. Our repair-or-replace guide explains how the door, frame, hardware, sill, and surrounding opening affect the decision.
Our Door Repair Process
Diagnosis
We inspect the door, frame, hardware, and surrounding structure to identify the root cause — not just the symptoms you're seeing.
Assessment & Estimate
We explain what's wrong, what it will take to fix it, and provide a clear estimate. If replacement makes more sense than repair, we'll tell you why.
Repair
We perform the repair using quality parts and materials — whether that's weatherstripping, a new threshold, jamb rebuilding, or hardware replacement.
Testing & Cleanup
We test the door's operation, check the weather seal, verify the hardware works smoothly, and clean up the work area before we leave.
Honest, Reliable Door Repair
We've seen every door problem imaginable, and we approach each one with the same principle: fix it right, fix it once, and don't sell you something you don't need. If a $15 weatherstrip will solve your draft, we won't try to sell you a new door. If your door genuinely needs replacement, we'll say so — and back it up with clear reasoning.
- Honest diagnosis — we recommend repair when repair is right
- Root-cause focus, not symptom patching
- Quality replacement parts and materials
- Experience with residential and commercial pedestrian doors
- Fast, reliable scheduling
- Clean, respectful work in your home or business
- Clear pricing before we start
Frequently Asked Questions
Minor warping can sometimes be corrected through hinge adjustment, shimming, or strategic planing. However, severely warped doors — especially wood doors that have twisted or bowed significantly — typically need replacement. We'll assess the extent of the warp and give you an honest recommendation.
Costs vary widely depending on the issue. Simple repairs like weatherstripping replacement or hinge adjustment may be quite affordable, while jamb rebuilding or threshold replacement involves more labor and materials. We provide a clear estimate before starting any work, so you know exactly what to expect.
Replacement usually makes sense when the door slab is warped or cracked, the frame has extensive rot, the door is 25+ years old with multiple issues, or you're dealing with repeated failures. If repairs would cost nearly as much as a new door, or if the door is a security or energy liability, replacement is the smarter investment.
No. A-1's repair work concerns pedestrian doors, not overhead garage-door systems. Describe the opening and symptom in your request so the service fit can be confirmed before scheduling.
It depends on the extent of the rot. Small, localized rot can often be repaired with epoxy or by replacing a section of the jamb. Extensive rot that has compromised the structural integrity of the frame requires full jamb or frame replacement. We assess the damage and recommend the approach that will give you a secure, lasting result.
Scheduling depends on the opening, location, parts, and current workload. Describe any security or access concern clearly and call 970-493-1630; A-1 will confirm the earliest available appointment without making an unsupported emergency or same-day promise.
The most common cause is a misaligned strike plate — the latch no longer lines up with the hole in the frame. This happens when hinges sag, the frame shifts, or seasonal humidity swells the door. In some cases, the latch itself is worn or the strike plate is loose. We diagnose the root cause and fix it: repositioning the strike plate, adjusting or replacing hinges, or shimming the frame so the door latches securely.
