Reviews

What San Diego homeowners say.

"TR Construction added a 600 sq ft master suite over our garage. They matched our Spanish tile roof perfectly and finished two days early. Feels like the house was built this way."

Carlos M.
Master Suite Addition

"They transformed our 1980s galley kitchen into an open chef's space with a 10-foot island. Permits were approved in three weeks and the crew cleaned up every night."

Jennifer L.
Kitchen Remodel

"Built a detached ADU in our Mission Hills backyard. TR handled the sewer upgrade, solar tie-in and even helped us pick low-maintenance landscaping. Rent covers half our mortgage now."
