Keen Mind Home Improvement

Sergei's work is FIVE STARS all the way! We have a 100 year old house that needed some exterior repair. A hard worker, his repair was flawless. And the clean-up afterward was complete! I would not hesitate to call him again next time.

Quality workmanship and excellent service!

We have owned several homes in different states and have worked extensively with home improvement professionals over the years. The work delivered by Sergei Pastalenka, owner of Keen Mind Home Improvement in Hyannis, MA, truly stands out—he is the best we have ever worked with. In addition to his craftsmanship, Sergei demonstrates exceptional professionalism, reliability, and integrity. Recently, we had an important event at our home and everything needed to be absolutely immaculate. At the last minute, one of our folding doors came loose and fell out of place, requiring urgent repair. We called numerous contractors—some didn’t respond, while others quoted unreasonably high prices. Sergei was the only one who answered immediately, confirmed that his on-site estimate would be free, and arrived within a few hours. He quickly identified the issue and repaired it confidently in minutes—he truly saved the day! His pricing was more than fair. Although this was a relatively small job, his attitude, responsiveness, and level of skill made a lasting impression. We have more projects planned, and Sergei will definitely be the one we trust to handle them.

Sergey is one of the most detail-oriented carpenters I know. Very personal in how he approaches each job, fair with pricing, and genuinely cares about the end result. Clean work, sharp execution, and you can tell he takes pride in doing things the right way.

I recently hired Sergei from Keen Mind Home Improvement to rebuild my front porch, steps, and install a new door — and the results were great! He’s knowledgeable and explains everything clearly, his pricing is very fair. The work was clean and finished on time. The craftsmanship shows in every detail. Highly recommend Sergei for high-quality work. I’ll definitely hire him again!
