During the last heavy rainstorm, our basement sump pump failed and water started coming in. Blackstone responded immediately, replaced the pump, and tested everything before leaving. Thanks to their quick action, we avoided thousands in water damage. Their technician even showed me how to maintain it properly. Fantastic service all around.

When we needed backflow testing for our home, Blackstone came highly recommended—and they lived up to it. The plumber was extremely knowledgeable and took the time to explain what was being done. Everything was completed efficiently, and they even helped file the necessary paperwork. A seamless, professional experience.

We’ve used Blackstone for everything from leaky faucets to installing new fixtures, and every time they impress us. The plumbers are polite, punctual, and take the time to explain the work. I really appreciate the transparency with pricing and the quality of the repairs. We finally feel like we’ve found ‘our’ plumbing company!

Our drains had been slowing down for months, and nothing seemed to help. Blackstone recommended hydro jetting, and wow—what a difference! Everything flows perfectly now. The technician explained the process clearly, and I was relieved it wasn’t as invasive or expensive as I feared. It feels like we got brand-new pipes.
