Keen Mind Home Improvement

A folding door that fell out of place before a home event prompted one April 2026 customer to call Keen Mind Home Improvement. They said Sergei answered immediately, confirmed a free on-site estimate, arrived within a few hours and repaired the door in minutes. A July 2026 customer described exterior repairs to a hundred-year-old house, praising the work and the cleanup afterward. Keen Mind describes itself as an owner-operated home improvement business in Hyannis, run by Sergei Pastalenka. Its website offers kitchen and bathroom remodeling, additions, interior work, siding, gutters, trim and window and door replacement. The company says Sergei worked in roofing and siding before moving into carpentry and earning a building license in 2019. Its Massachusetts home improvement contractor registration is active under Keen Mind Inc. Google shows a five-star average from 24 ratings. Doors, windows, steps and porches feature in customers' accounts. In a November 2025 review, a homeowner described a rebuilt front porch and steps plus a new door, with clear explanations, fair pricing and completion on time. Another customer writing that month said Sergei installed a front door and storm door for a Cape summer house, explained the differences between brands and worked around a schedule that included visiting guests. A July 2024 customer praised his work on a side door and frame, saying he listened to their concerns and answered questions. For windows, a November 2025 reviewer reported that replacements had stopped the leaking in their home. A separate reviewer that month described replacement of a cracked window and a clean, tidy finish. Another November 2025 customer said Sergei had prepared their house for sale with a new roof, siding, painting and interior trim. Customers also describe repairs to animal damage. In November 2025, one homeowner said raccoons had chewed through the roof and soiled the attic; they reported repairs, a replaced floorboard and raccoon spikes installed on the roof. A different reviewer that month described Sergei finding a dead squirrel beneath attic floor sheathing and replacing affected materials the same day, after which the odor disappeared.
