A bathroom renovated five years earlier still looked new to one customer writing in August 2026. That reviewer also described Konstantin replacing three bedroom and bathroom door locks that another contractor had said would require replacing the doors. KB Home Improvement's website describes a family-owned residential remodeling business with ten years in business, offering bathroom work, painting, drywall, tile and flooring. Bathroom projects range from repairs to full renovations. In a December 2024 review, a couple described a shower that had leaked into their cellar in 2023. They said Kosta assessed the leak and repaired and retiled the lower part of the shower rather than gutting the whole installation, saving them money. They subsequently hired him for a full remodel of their original 1968 bathroom. A November 2025 reviewer described a completed full bathroom remodel with aligned tile, no last-minute price changes and no delays. The work extends beyond bathrooms. An April 2026 customer described a new basement room, including framing, insulation, walls, plaster, a drop ceiling and doors. They also praised the replastering of old textured walls and ceilings. An August 2026 reviewer described replacement of two large kitchen windows and said Kosta suggested keeping the old frames to avoid further wall damage. Their kitchen renovation was still a future plan. In a July 2024 review, another customer described sanding, staining and coating hardwood floors and praised prompt responses to questions. Customers also describe how Kosta handled decisions and communication. In a May 2025 review, a homeowner said he explained options and relative costs, answered product questions by text, and removed mold while correcting work left by previous owners. The customer also described him removing an already-placed tile when they disliked its appearance. An August 2025 reviewer praised on-time arrivals and quick replies to questions. A June 2024 reviewer had a different experience before work began. They said they called about two full bathroom remodels and a partial master-bathroom remodel and were told it would cost $35,000 before anyone looked at the project. The reviewer objected to being asked whether that amount fit their budget before a visit. The Massachusetts registry confirmed active home improvement contractor registration 194096 under Konstantin Bukharev in August 2026. The company's website says it offers free estimates.
Konstantin is very thorough with his work. He did a total bathroom renovation for me five years ago, and It still looks like new. Today he came by and replaced three locks on bedroom and bathroom doors in my new condo. Previous contractor told me these types of locks couldn’t be replaced with regular locks, but only with similar skeleton key locks. And that my only choice was to replace the whole door. Konstantin replaced the locks using his skill and creativity.
This year we had a small project: replacing 2 large windows in our kitchen. We haven’t renovated our kitchen yet, that’s definitely on a horizon; and no one else but KB Home Improvement will get this contract without any hesitation. But for now, we desperately needed 2 windows replaced because the old ones were drafty with zero insulation. After last winter I said to my family: we can no longer suffer this draft and wind going inside our kitchen. Kostya, being super busy, as he always is said that he will be happy to do it. He came early spring to make measurements and estimate the materials needed for the job. He also suggested to keep the old frames for the time being not to damage the walls further. But promised that the new windows will be properly installed, insulated and frames refreshed for a new look. The results speak for themselves: super happy with exceptionally well done job! Kostya is a true professional and master of his craft! Can’t thank him enough!!!
KB Home Improvement, thank you for your professionalism!! Very professional in every way. No nonsense AT ALL, just great work. Very thorough, and honest and priced very fair. Had a whole new room added to my basement that Kosta saw through from beginning to end and it came out awesome. Framing, insulation, walls, plaster, drop ceiling, doors…. He did it all, and did it just great.. They also re-plastered my old, outdated, textured walls and ceilings to unbelievably smooth and flat. Like brand new walls. It was honestly like magic. I couldn’t believe it would be that nice when it was finished. Very appreciative of this kind of professionalism. Thank you Kosta!
KB Home Improvement is an excellent company to work with. Kosta and Team are very professional, honest, and provide quality work at a fair price. I am impressed with their work ethics. Colleen C.
We recently completed a full bathroom remodel, and working with KB Home improvements was truly one of the best decisions we’ve made as homeowners. From the very first consultation to the final walkthrough, their professionalism, attention to detail, and pride in craftsmanship were unmatched. The quality of the work speaks for itself: every tile is perfectly aligned, the finishes look high-end and custom, and the final result feels even better than what we originally envisioned. Equally important, the process was stress-free. There were no unexpected surprises, no last-minute price changes, and no delays. It's rare to find a contractor who is reliable, honest, and incredibly skilled. We now have a beautiful, modern bathroom that and we couldn’t be happier.
