A window replacement touches the most critical envelope of your home. Here is the process we follow to ensure zero water infiltration and maximum efficiency.
Window replacement takes 1-3 days for a full house (15-20 windows). The two methods are insert replacement (faster, keeps existing frame, $300-$700/window) and full-frame replacement (removes everything to studs, $500-$1,200/window). Full-frame is recommended when existing frames show rot, water damage, or you want to change window size.
| Factor | Insert (Pocket) | Full-Frame |
|---|---|---|
| What's removed | Sashes only | Entire window + frame |
| Time per window | 30-60 minutes | 1-2 hours |
| Interior disruption | Minimal | Moderate (trim removal) |
| Glass area | Slightly smaller | Maximum glass |
| Insulation opportunity | Limited | Full cavity access |
| Cost per window | $300-$700 | $500-$1,200 |
| Best for | Good frames, budget | Damaged frames, upgrades |
It depends. Same-size replacements typically don't require permits. Changing window size, adding windows, or structural modifications require permits. DT Exteriors checks with your municipality and handles permits when needed.
