"Express was one of four companies I talked with... I chose them for their fair prices and communication (they listened, answered questions, provided timely follow-up). I'm very happy with the work that Express did. Overall, the work came out great and I'm thankful it went as smoothly as it did."

"We have a rental that needed full kitchen and bathroom remodel. Val and his team handled everything. Cabinets, counters, backsplash, plumbing, flooring, all of it. The place looks great and the tenants are happy and the work was solid. They showed up when they said they would, and got it all done faster than the timeline they gave me."

"A burst pipe flooded our main retail floor late Saturday night. Express Restoration responded immediately and had extraction trucks on-site within an hour. Their rapid response saved our inventory and they worked around the clock so we didn't have to close our doors on Monday. Outstanding commercial partnership."

"Their team did exceptionally beautiful work! They took no shortcuts, like painstakingly cutting an intricate piece of molding to perfection... What REALLY separates them from the rest is the respect they showed for our home and, frankly, for us."
