Hired on Thumbtack

I hired a guy to install a dishwasher while renting out my house and couldn't be there. He had very high ratings on Thumbtack but all I heard by phone were excuses about things I knew any competent installer could do. Sure enough, Castillosa got to the house within a day or two and had it installed quickly and competently for a fair price. My tenants were happy.

And when they did something to back it up and said they thought there was something wrong with the install (there wasn't), Castillosa followed up with me quickly and would have gone back out if the tenants hadn't run it the way I told them, which fixed the "problem."

I really appreciate people like Castillosa who stand behind their work - it's a rarity in that area - and I'll use him again if needed.

Wow 🤩! Would give them 10 stars ⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️ if I could! They were extremely professional and proficient. The storm blew my mailbox over and broke it. I needed it replaced asap, and they came to replace it the next day in the morning.

I will definitely be hiring them again for future projects I need done around the house.

Highly recommended! Thank you for great quick quality service.

I had a very professional experience with this company. I needed a baby gate installed and it was installed to perfection. He took photos and was honest with his pricing . I will hire again !
