I am amaze with their work, very efficient and professional. Complete within a few hours. And test it in front of me. No more leakage. Will definitely recommend KH.

I am facing consistent water leaking problem for my car porch. Gotten a few contractors. They did PU injection, didn’t really solve the problem. After engaging KH, problem solved

KH is very efficient and detailed with their work. They came down, spotted the problem, explains to me, and provide me with a solution. I am amaze by this chemical they are using. Thumbs up.
