Magnoli Home Improvements is a Canton, CT windows, siding and doors contractor run by David Magnoli. The About text on its website tells a first-person story: framing custom homes with a Bristol, CT company starting in the early 90's, then joining a window and remodeling company out of Southington, CT in 2006. The company claims 30 years in business and lists a service area of Avon, Barkhamsted, Bloomfield, Burlington, Canton, Farmington, Granby, Simsbury, Bristol and Southington. Its Connecticut home improvement contractor registration, HIC.0661313, is active on the state registry under Magnoli Home Improvements LLC. A 2026 customer said Dave was straightforward and transparent through a replacement window project and left the house cleaner than it was when he started. A 2025 customer described a window installation by David and his son that left the home clean and tidy. A 2025 reviewer who hired the company for siding replacement said David kept them in the loop and showed up himself to check the work site at the start and end of each day. The jobs go well beyond windows. A 2023 customer hired David for a front porch remodel with new flooring, pillars, ceiling and a swing installation. A 2023 reviewer listed a storm door install, an interior door, garage work including a walk-in door, a shed roof and setting a sliding barn door right. A 2022 customer said David installed new windows and a microwave above the range, replaced rotten wood on the porch and built a new outside staircase. A 2022 reviewer said Dave replaced windows, doors and siding, arrived on time for every consultation and every scheduled work day, and finished in the estimated time frame; unexpected issues the house threw up mid-project were brought to that customer's attention and fixed. A 2022 customer who needed a door replaced on a rental said the work was done within a few weeks. A 2026 reviewer who had worked with Dave in the past wrote that they had been trying to reach him for months and asked whether the business was still operating.
Hi, does anyone know if Magnoli Home Improvements is still in business? I've worked with Dave in the past and he was AWESOME but have been trying to reach him for months.
Dave was awesome! He was friendly, straightforward and transparent with us through the whole process. Right away we felt comfortable with him handling our replacement window project. He does awesome work and even took the time to make sure he left our house cleaner than it was when he started.
We had an excellent experience working with David and his son on our window installation today. From start to finish, they were professional, efficient, and incredibly friendly. They took great care in their work, making sure everything was done perfectly and left our home clean and tidy when they finished. The new windows look amazing, and we can already feel the difference in the comfort of our home. It was clear they take pride in what they do, and we truly appreciated their attention to detail. Highly recommend David and his son to anyone looking for quality work and a team you can trust!
This review is long overdue and I'd like to take a moment to rave about Magnoli Home Improvements, a top notch contractor in Canton, CT. We chose them for our siding replacement and couldn't be happier. The owner, David, is a wizard in this business - he knows his stuff as he's been doing this for many years, super professional and most importantly, a REALLY good guy. He's basically a unicorn in this industry! His pricing is reasonable considering the value he delivers is off the charts. David kept us in the loop throughout the project, ensuring everything was just right and we were happy with the progress. His guys were super neat and clean and David himself showed up to make sure the work site was in proper order at the start and end of each day. The end result was simply phenomenal and even our neighbors agree! Months later, our house still looks amazing, like it's fresh off a makeover. We can't wait to have Magnoli Home Improvements on board for our next big project, and honestly, you should consider doing the same. Trust me, your home will thank you!
David and his team blew away all of our expectations. The job was a big one and it was done quickly, efficiently and neatly. Everyday I came home, something significant was completed. David is true craftsman and it shows through his attention to detail. I can’t say enough about how happy we are. We can’t wait to work with Magnoli Home Improvements on our next project!
