Missing The Signs Of A Poor Install

When those steps are rushed, homeowners often end up with drafts, water intrusion, or trim that never sits right again.

A homeowner should also think about security, sound, and everyday operation before signing off on the work.

A short checklist can help keep the project on track:

Ask how flashing, insulation, and cleanup will be handled. Get clarity on warranty coverage and what it actually includes.
