What San Jose homeowners say.

"Lemon added a 280-sq-ft nursery over our garage in six weeks. They matched the stucco and roof tiles perfectly—neighbors still think it’s original."

Kevin R.
Second-Story Addition

"We turned our 1980s galley kitchen into an open chef’s space with a 9-ft island. The crew protected our hardwood floors and finished on the exact day promised."

Lisa M.
Kitchen Remodel

"Lemon built our backyard studio apartment in 11 weeks. It rents for $2,200 a month, and the city inspector signed off without a single correction."
