Dog Door Repair vs. Replace: How to Decide
A worn flap doesn't mean a new door — but a cracked frame usually does.
Signs you can repair
- Flap is torn, curled, or brittle but the frame is straight
- Magnets and weather brushes are gone or ineffective
- You feel a draft, but water doesn't intrude around the opening
- Locking panel is lost or bent (replaceable part)
Signs you should replace
- Frame is cracked, warped, or pulling away from the door
- Water intrusion or rot around the opening
- Dog has outgrown the size class
- Original install was undersized or crooked
Cost comparison
| Work | Typical range |
|---|---|
| Flap replacement | $95 – $175 |
| Full parts refresh (flap + magnets + brushes) | $150 – $275 |
| Frame re-secure or re-seal | $175 – $325 |
| Full pet-door replacement (entry door) | $650 – $1,400 |
| Full in-glass replacement | $1,200 – $2,400 |
DIY vs pro
Flap and brush swaps are straightforward if you have the exact replacement part. Frame or glass work isn't — a bad reseal lets water in and can rot the surrounding jamb within a season. Get a quote before opening anything up.
Extend the lifespan
- Wipe magnets and weather brushes twice a year
- Use the lockable panel during storms and travel
- Trim overgrown landscaping away from the flap
- Swap flaps before they fail, not after — usually every 4–6 years in Colorado
