About
I specialize in hydronic radiant floor heating systems and professional flooring installation. With 11 years of experience in radiant heating and 9 years in flooring, I handle full house and basement projects, as well as remodels and complete floor replacements.
I design and install hydronic systems correctly from the start, including proper loop layout, manifolds, insulation, and system balance, so the heating works efficiently and reliably. I’m experienced working with difficult floor conditions and older homes where mistakes are costly. I don’t do rush or temporary fixes. All work is done properly and backed by a written warranty.

I had an excellent experience working with KSV Services LLC. They removed the old flooring, installed radiant heating (heated floors) in the main areas of our home, and then professionally installed beautiful hardwood floors. The entire process was smooth, fast, and very well organized.
The quality of their work is outstanding — everything was done carefully, cleanly, and with great attention to detail. It has been over a year since the installation, and the floors still look absolutely perfect.
What I especially appreciated is their professionalism and the warranty they provided. Even though we haven’t had any issues at all, having a warranty gives peace of mind and shows how confident they are in their work.
I highly recommend KSV Services LLC to anyone looking for high-quality flooring and radiant heating installation. Reliable, skilled, and trustworthy team.

I had a great experience working with KSV Services LLC. After purchasing an older home, Sergei removed the old flooring and installed 1,000 square feet of engineered hardwood. The transformation was amazing, and I’m very happy with the result.
Highly recommend!
