Door repairs — new weatherstripping, hardware, or a fresh coat of paint — extend the life of a door in good structural condition. But once the frame has warped, the glass seal has failed, or the door no longer seals or locks securely, repairs restore appearance, not performance or security.

## Signs It's Time to Replace (Not Just Repair)

These indicators—from contractor experience and industry data—signal that repair costs will exceed replacement value, or that underlying damage makes spot repairs futile.

1

### Warping, cracking, or cupping in the door slab

A door that's visibly bowed, cracked, or no longer sits flat in its frame has structural damage that hardware adjustments can't fix. This is most common in wood doors exposed to sun and moisture without regular refinishing.

2

### Sticking when opening or closing

A door that binds or drags along the frame usually means the frame has shifted or the door itself has warped. Planing the edge helps temporarily, but recurring sticking after adjustment means the underlying structure has moved.

3

### Drafts you can feel at the frame

If you can feel airflow around the edges of a closed door, the weatherstripping has compressed permanently or the frame has warped enough that it no longer seals. Weatherstripping replacement helps on a straight frame; a warped frame gaps again quickly.

4

### Condensation or fogging between glass panes

For doors with insulated glass (sidelights, patio door panels), fogging between the panes means the seal has failed and the insulating gas fill has escaped. There's no field repair — the glass unit or the whole door must be replaced.

5

### Daylight visible around the edges when closed

If you can see light around the door frame with it fully closed, air and water can follow the same path. This is a security and energy-loss issue that weatherstripping alone won't solve once the frame itself has gapped.

6

### Door no longer locks or seals securely

A deadbolt that doesn't fully engage, or a door that can be pried open at the frame, is a security issue — not just a comfort one. If hardware adjustment doesn't resolve it, the frame or door itself needs replacement.

## When Repair Is the Right Call

Not every problem requires full replacement. Here are situations where targeted repair is cost-effective.

| Situation | Recommended Action |
| --- | --- |
| Hardware failure: locks, hinges, or a closer | Replace the hardware — the door slab and frame may be fine. |
| Weatherstripping worn or compressed | Inexpensive repair that restores a good seal if the frame is straight. |
| Exterior paint or stain failure on an otherwise sound wood door | Refinish rather than replace — sand, prime, and repaint or restain every 3–5 years. |
| Single broken pane in a multi-pane door | Glass panel replacement is possible on many doors and costs far less than full door replacement. |

## What Goes Into a Door Replacement Project: Material Reference

Door replacement bids vary because the door unit itself is a large share of cost and quality varies widely between steel, fiberglass, and wood. Here's what a complete door replacement scope should include.

| Material / Component | Details & Typical Quantities |
| --- | --- |
| **Door slab and frame unit** | $300–$3,500+ per door depending on material and size. Steel is most affordable; fiberglass adds insulation and dent resistance; wood offers the most design range but the highest maintenance. Ask for the specific brand and series in writing. |
| **Glass package (if applicable)** | Sidelights, transoms, and full-glass patio doors: low-E coated, insulated glass is standard on quality installs. $100–$800+ depending on size and coating. Ask for the U-factor in writing. |
| **Threshold and weatherstripping** | A new sill/threshold and full perimeter weatherstripping should be part of any full door replacement — not a reused component from the old door. $50–$200 for materials. |
| **Hardware (locks, hinges, handleset)** | Basic hardware is often included; premium handlesets and multi-point locking systems are typically an upgrade. $50–$400+ depending on grade. |
| **Flashing tape and sealant** | Self-adhering flashing tape at the rough opening and high-performance exterior sealant (Sikaflex, OSI Quad) at the frame perimeter: standard practice, should be included. |
| **Interior trim/casing** | If existing trim is removed and replaced: $50–$150 in labor and materials. Verify whether trim removal/replacement is included or extra. |

## Frequently Asked Questions

These are the questions homeowners ask most often before starting this project - what it costs, how long it takes, what a fair quote looks like and which details change the price. Each answer below is written to stand on its own, so you can read just the one you need.

### How do I know if my door needs replacing?

The clearest signs are a warped or cracked slab, a frame that no longer seals, fogging between glass panes, and a door that won't lock securely. Cosmetic wear on an otherwise sound door usually doesn't justify replacement cost.

### Can you repair a door that won't close properly?

Sometimes. If the issue is loose hinges or a shifted strike plate, a quick hardware adjustment fixes it. If the frame itself has warped or the house has settled, repair is often temporary and replacement is the more durable fix.

### Is a drafty door always a reason to replace it?

Not necessarily. Drafts can sometimes be fixed with new weatherstripping — a much cheaper repair. If the frame itself is warped or the draft is severe and returns quickly after weatherstripping, replacement is the better long-term investment.

### How long does a door last before it needs replacing?

Steel and fiberglass entry doors typically last 20–30+ years with basic maintenance. Wood doors need more frequent refinishing and may need replacement sooner if moisture exposure isn't managed. Patio door glass seals typically last 15–20 years before failing.

### Do I need to replace my patio door and entry door at the same time?

No — they're independent decisions. A failing patio door doesn't mean your entry door needs replacing too. Get a separate quote for each unless you're doing a full exterior refresh.
