Gavin and Trinity Design Build has been a dream to work with. We did a remodel with a different company at our prior home and it was a nightmare. Working with Gavin was a day and night difference.

We were referred to Gavin and Trinity Design Build by another general contractor after they weren’t able to get our project going, and we are so glad they did! Gavin was able to pick up the project and our new backyard covered patio exceeded our expectations!
