"AJ Contracting handled our 650 sq ft great room addition from drawings to framing and final trim. Their framing crews are punctual, tidy, and built the structure like a fortress. Completely seamless tie-in to our existing roof."

"We needed custom structural framing for a two-bay detached garage and workshop. They handled the permit inspections without a single hiccup. You can immediately see the 40+ years of trade experience in the precision of their framing."

"They removed two load-bearing walls to give us an open-concept kitchen and main floor. Honest quoting, zero surprise costs, and clear daily communication on progress. Easily the most reliable general contractor we've worked with."
