Smart Installs LLC is an Amherst, New Hampshire exterior-renovation contractor led by founder and owner Gleb Liashko. The company says it installs and replaces windows, doors, siding, roofing, and epoxy flooring for homes and commercial properties, and offers free estimates. Its BBB profile lists an A+ grade and accreditation. The clearest track record is in windows and doors. Google publishes a 5-star average from 66 ratings, while Angi shows 5.0 from six ratings. Recent 2026 homeowners describe multi-window replacements, bay windows, patio doors, entry doors, and Marvin products; they repeatedly mention crews arriving on time, protecting and cleaning the work area, explaining the process, and handling installation details carefully. Several reviews are unusually specific, including a 14-window subcontracted installation, a five-day whole-home window project, and follow-up work on exterior rot and window trim. Siding also appears in both the company's stated service list and customer accounts, while roofing and epoxy flooring are listed as offered but have less detailed customer-job support in the quoted history. Before booking a broader exterior project, confirm which crew will perform that scope, the product and workmanship warranty terms, and the expected schedule in writing. A 2025 reviewer specifically described manufacturer-trained Marvin installation and warranty support, making product-specific coverage a useful point to verify. Smart Installs is best matched to homeowners comparing window, exterior-door, and siding contractors who value responsive communication and tidy installation. Ask for a written scope covering materials, trim or rot repairs, cleanup, permitting responsibility, and warranty coverage for the exact products selected.
Smart Installs did a great job replacing our homes windows. They were professional, respectful of our home and property, and true craftsman in their trade. The project took 5 days and they kept us informed every step of the way and made sure the completed project met our expectations.
Smart Installs LLC was the subcontractor hired by Renewal by Anderson to install 14 windows. They could have not picked a better company for this project. The crew showed up on time, went over the project with us, answered all the questions we had and got to work. They worked as a team and the workmanship was outstanding. The wrap around some of the windows was challenging but when completed it was flawless. The customer service exceeded my expectation. I would highly recommend Smart Installs LLC for window needs and any other services they offer.
I had a large bay window replaced. The crew arrived on time and got right to work. All three install guys were friendly, professional and hard working. I can recommend this company with confidence and will be scheduling a front door install with them soon.
Smart Installs replaced my windows and two entry doors, and I chose Marvin products for the project. The installation quality is excellent, the team arrived on time each day, and they cleaned up thoroughly after the work was done. Very satisfied with the results and would highly recommend them.
I own an Airbnb in northern New Hampshire and recently had a patio door replaced by Smart Installs LLC. The process was straightforward from start to finish. Communication was clear, scheduling was quick, and the crew showed up on time and worked clean. The new patio door looks great and works smoothly, which is important for guest comfort. Smart Installs did solid, professional work and I would use them again.
