After a heartbreakingly high quote to paint our kitchen cabinets, I impulsively sent a message to Boom through Thumbtack, and two weeks later, I have a whole new kitchen!
I can’t believe how quickly we were added to the schedule. The crew was professional and hard working. I was impressed with their finishing work and the care they put into the clean up once the painting was complete.
Looking forward to working with Boom in the future when we’re ready to tackle the bathrooms!

Santiago replaced a simple 12x24 30 year old (and rotting) ground level deck with beautiful cedar decking on the front of a rambler (rental) home I own. He added 2 sitting benches and two sets of stairs and clear-coated the finished product. He was on time and finished project in the timeframe he quoted and responsive during the project. The quality was great - he easily captured my idea of the new design I made a rough sketch of. I will hire him again to refinish the yard fencing and siding on the house. He does quality work and communicates throughout the project and has a great work ethic. I'd hire him again in a heartbeat!

Santiago and his team were great and completed the project (painting kitchen cabinets white) in only two days. We love the finished product and the price was great too!
