Decks are in the name, but JWS Custom Decks LLC also takes on garages, additions, remodels, siding, windows and farmers porches, by its own description on the BBB. Its website claims 25 years in business and lists a service area that includes Candia, Bedford, Goffstown, Raymond and Concord. A recent customer had a bay window removed and a slider framed and installed, and praised the workmanship. A recent customer said the company replaced their deck and later their front porch, and praised the attention to detail and the quality of the construction. A recent customer credited James and his crew with a new roof and windows and praised the price. A 2024 Google customer described a custom 24x36 two-level, three-car garage with one cathedral bay built to fit a vehicle lift, framed with I-beam and LVL, and called the team clean and professional. A 2017 Angi customer said James built their two-car garage, cleaned up at the end of every day, and gave an honest opinion on what would and would not work in the design; that customer said the garage fits in with their house, built in 1890. A 2020 Angi customer said a job quoted at three weeks still had only footings and foundation walls, with no slab, after five weeks. That 2020 customer said a dispute over $3000 more than the $1000 they said they were told ended with James Shankle walking off the site, and that the matter went to court. A 2022 Google customer said an estimate visit was promised on two separate dates and he never showed either time.
Excellent Job done by James and his Crew on our New Roof and Windows, Great Price, Great Workmanship.! I would recommend, and will use again in the future .
We had our deck replaced 2 years ago and were so happy with the beautiful job these guys did! This year they replaced our front porch and once again, they went over and above our expectations! The attention to detail and the quality of their construction is outstanding. Call them, you won’t be disappointed.
Exceptional service from a family owned business! The owner and manager are very friendly, professional and knowledgeable in what they do. I have recommended them to everyone I know! Will be utilizing their services again in the near future.
JWS Custom Decks removed a bay window , framed and installed a slider for me..Outstanding workmanship I'd recommend..
This guy built a custom 24x36 two level three car garage for me with one bay custom cathedral to accommodate a vehicle automotive lift. Not only is he genius with designing building it all using I Beam, and LVL his team is extremely clean and professional. My garage continues to be my show piece. So if you can get this company, I would recommend them hats off.
