Jancon Exteriors is a Franklin, Massachusetts crew that homeowners keep calling back for one project after another — repeat customers show up again and again in its Google reviews, several saying this was their second or third job with the company. The company, run by owner Jeff Swahn, describes itself as an exterior remodeling contractor working siding, roofing, windows, doors, decks and storm-damage repair with in-house crews rather than subcontractors, and says it covers Franklin and the surrounding towns into southeastern Massachusetts and northern Rhode Island. Across 74 reviews dating back to 2014, the pattern is consistent: full re-siding jobs, roof replacements, window swaps, and deck builds that reviewers describe as thorough, on schedule, and left clean at the end of each day — one reviewer specifically noted the crew "cleans EVERYTHING up" before leaving, and another called the daily site cleanup "efficiently hauled away." The work has also stretched well past exteriors: several homeowners hired Jancon for full kitchen gut renovations, multiple bathroom remodels, room additions, and one complete rebuild after a house fire. Ten reviews landed in the last six months, all positive, on top of a 4.8-star Google average from 78 ratings, a matching 4.8 from 504 Porch ratings, and a 5.0 from 61 Best Pick Reports ratings. The written record isn't spotless. A 2023 review said a window order took four months to arrive and a promised follow-up job never materialized. Further back, a 2018 Houzz review alleged the company tried to profit from the reviewer's home-fire insurance claim during a full rebuild — a serious, dated account worth knowing about even though it predates most of the company's recent work. The company holds an active Massachusetts home improvement contractor registration, verified against the state registry, carries an A+ Better Business Bureau rating, and lists manufacturer certifications with CertainTeed, James Hardie, and Mastic. Jancon Exteriors reads like a strong fit for a full exterior overhaul — siding, roofing, windows, or a deck — and has a track record of taking on larger interior renovations too. Given the 2018 complaint, it's worth asking directly about how they handle insurance-driven jobs before signing on for one.

Jancon did a fantastic job on all of our work! We could not be happier. We first hired Jancon to replace our windows. They did such a fantastic job that we had them gut and renovate our kitchen, remodel 3 bathrooms and refinish our hardwood floors. The quality of workmanship was second to none. Jancon’s communication was excellent - we were continually kept up to date and in the loop. The projects were finished on time and on budget. I cannot thank Jeff, Rob and the entire team enough. We will enthusiastically recommend Jancon to anyone that may be considering work on their home!
Jancon transformed my old concrete front steps and landing into a porch I can be proud of! Their work is very professional and precise and their crew is comprised of some of the most hardworking individuals I have ever dealt with - and I’ve dealt with many in my 81 years! Don’t hesitate to contact them - you won’t be disappointed! Thanks again Jeff, Rob, and crew!
We couldn’t be happier with our experience with Jancon Exteriors! They transformed our backyard with a beautiful deck and helped us create a more functional space inside our home. Their communication and craftsmanship were outstanding from start to finish. Thank you for bringing our vision to life and for putting up with my perfectionist tendencies along the way! We truly appreciate all of your hard work and would recommend Jancon Exteriors to anyone without hesitation.
We can't say enough good things about Jancon Exteriors! Jeff and his team completely transformed our home, and they didn't just meet our expectations — they blew right past them. The scope of this project was huge: a full new roof, gutters, fascia, and Hardy Pearl Gray siding, plus a total overhaul of our oversized deck. Every single piece came together beautifully. The siding color is gorgeous and gives the whole house a fresh, modern look, and the roof and gutter work is clean and solid from every angle. The deck turned out even better than we imagined — it's now one of our favorite spaces. Jeff and his crew were professional, communicative, and clearly took pride in the quality of their work throughout the entire process. It genuinely feels like we're looking at a brand new house. If you're on the fence about who to hire for a major exterior project, stop searching — Jancon Exteriors is the team you want. Thank you, Jeff and team, for such an incredible transformation!
Outstanding from start to finish! Quick and easy first meeting, efficient proposal without the continuous sales pitch. Gentleman that did the work … can’t say enough about his quality, efficiency, and work ethics. 5***** all around. Love love love the finished product! You can’t go wrong with Jancon Exteriors!
