Get a Free Estimate"Onyx turned our cramped 2-bed into a 4-bed with a master suite and walk-in closet. They matched our 1950s hardwood perfectly; you can't tell where old meets new."
"We added a 480 sq ft ADU where the old garage sat. Rented it on day one for $2,800/month. Onyx handled permits, solar tie-in, even landscaping."
"Kitchen reno included moving the range gas line and adding an island. Finished in 5 weeks and came in $3k under estimate. Clean crews every day."
