A 2025 Reddit thread in r/Somerville put it plainly: a good reliable GC is tough to come by — and the commenter's pick was Iannelli Custom Contracting, which had been the GC on their Davis Square store. In a June 2025 r/medfordma thread, another commenter called Iannelli Custom Contracting excellent. The company works out of 12 Manning St in Wilmington and describes itself as carpentry-led, specializing in high-end finish work and custom design alongside remodels, additions and painting. Most of what reviewers describe is exacting work inside houses people are still living in. A December 2025 customer had a large structural update done to the ceiling in the middle of their house while living and working in that space around the clock, and said the crew took it from demolition through finishing. Another the same month described a new picture window — careful measuring, a neat and precise install. A July 2024 reviewer said the team evaluated and resolved an issue another provider had failed to fix after three attempts. The custom pieces come up again and again. A July 2022 customer described a walk-in closet and headboard that included a barn door built from reclaimed wood; another that same month listed jobs running from a shed restoration to a backyard overhaul with fencing and a designed deck. In 2024 a customer wrote about a closet buildout, built-in shelving and a difficult front door installation done by Dave and his brother. Windows and doors are a steady line too: a 2023 reviewer said the company came recommended to them as Andersen Windows installers and that in 2022 it replaced four windows, a sliding door, a front and storm door, and handled interior painting. Houzz shows six projects around the inner suburbs — an Ipe fence in Cambridge, an Ipe deck in Lexington, a cedar potting shed in Arlington. BBB grades the business A+ and lists David Iannelli as owner with four employees and a start date of 11/1/2017, and Google carries 20 ratings averaging 5.0 across 19 written reviews from 2022 to 2025. For finish carpentry, built-ins, a deck or a window-and-door job handled by a small crew that several customers have hired more than once, this is the kind of shop that fits. With four employees, ask about the schedule before you commit, confirm who will be running your job day to day, and get the scope and change-order terms in writing.
“A good reliable GC is tough to come by, but Iannelli Custom Contracting is great. David Iannelli is the owner and GC. He was the GC for my store in Davis Sq.”
“Iannelli Custom Contracting - they're excellent!”
David and his team really went the extra mile for us. Our ceiling needed a large structural update in the center of our house, which felt risky to do while we were living and working 24/7 in that space. The Iannelli team executed every step from demolition through finishing with surgical precision. They kept the entire project completely contained in a small space, worked around our schedule so our lives were not disrupted, and finished in a matter of days. They were also really nice so it wasn't annoying having them around. We're also really pleased with how the project turned out. While it was a damage repair/mitigation project, it looks great and has made our space look and feel much better. We were especially pleased that the team saved and re-used the trim that divided the affected rooms, keeping the look consistent and keeping our costs down. That level of attention to detail when the main focus was installing a massive new beam across our house was super impressive. We'll definitely be coming back to Iannelli Custom Contracting for any new projects, and highly recommend them!
David and his workers did a beautiful job installing a new picture window for our home. From the detail work on measuring and meticulous work on install we felt comfortable. The work done was neat, careful and precise from what we could see and care was paid to not damage anything in the house as they worked. We had asked for the window to match our existing window trims inside and out and they did a perfect job. The new window is beautiful and as an Andersen Installer combined with the care in the work they did we felt confidence in the process.
Beautiful work. Clean and respectful crew.
Dave and his brother have done numerous projects (a closet buildout, built-in shelving, and a difficult front door installation) for us. Their precision, skill, and attention to detail are outstanding. I look forward to working with them again on a bigger construction project.
The Iannelli team is amazing! They do great work and are wonderful to work with.
