Build Smart—Avoid Costly Do-Overs
- Don’t:
- Sign the lowest bid that skips permits—town inspectors can halt work mid-build.
- Ignore insulation and flashing—hidden gaps invite water, mold, and high energy bills.
- Forget snow loads—roofs, decks, and exterior home additions in NH need strength for heavy winters.
- Do Instead:
- Check insurance, licenses, and local reviews before hiring.
- Demand full building-wrap, proper footings below frost line, and stainless or coated hardware.
- Get a clear timeline and warranty in writing—quality builders stand behind their work.
Follow these tips and your exteriors and additions project will stay solid, safe, and good-looking for decades—no rot, no fines, no regrets.
