CAZ Construction

CAZ Construction, founded in 2010, is a Bellingham-based design-build firm serving Whatcom County with an integrated team covering design, carpentry, electrical, plumbing, insulation, and more. With a 4.9-star rating across 126 reviews, they have built a steady reputation for whole-home projects spanning custom builds, remodels, and targeted repairs. Their multi-trade structure means every phase from concept to finish stays under one roof, which tightens quality control and keeps projects on schedule and on budget.

What sets CAZ apart is their genuine in-house integration. Rather than juggling subcontractors, they deploy their own crews for insulation, crawl space sealing, ductwork, and electrical upgrades simultaneously. Their design-build methodology lets homeowners collaborate with one team from initial sketches through final walkthrough, eliminating hand-off delays and miscommunication. Several reviewers specifically noted how smoothly crews coordinated between trades, with jobs completed in days rather than the weeks a fragmented approach often demands. This internal capability is the engine behind the efficiency praised across their feedback.

Reviewers repeatedly named technicians who went beyond standard expectations. When Ave Kemper needed crawl space insulation during a pouring rainstorm, the crew finished with zero details missed and left the space immaculate. After the Gallaghers required whole-house rewiring to remove decades-old knob-and-tube wiring, the CAZ team brought the junction box up to code while handling a 220-volt stove outlet and outlet repairs in the same visit. Heat pump and mini-split installations by Mardo and his crew drew specific praise for on-time arrival, neat cable runs, and thorough cleanup.
