Universal J & S Construction is a Quincy company that customers hired mostly for roofs, decks and porches, and most of its reviews were written in 2020 and 2021. Angi and HomeAdvisor each show 4.7 stars from 63 ratings. Roofs come up again and again. In an August 2020 Google review, a customer who had just bought a house said J & S replaced the roof, offered options and sent updates during the job. A May 2021 reviewer said they had used the company to replace three roofs, and a December 2020 customer said Weuler and his team fixed a leaking section of roof with no surprises, though the crew started in the afternoon and finished in the dark, which made nail cleanup hard. Decks and porches come up too. In an October 2020 review, a customer said a job adding stairs and new railings to a deck was done in just over a day, and the crew came back the same day to fix the small things they pointed out. A September 2021 reviewer said the company repaired deck steps for less than two other estimates, and a February 2025 reviewer said Jonatas had done four decks so far. In October 2020, a customer said the company took a deposit and missed two promised date ranges without showing up. A January 2021 reviewer called the company a scam, naming a salesman, a contractor and the owner as working together. Its Massachusetts HIC license, #192081, is expired on the state registry.

Jonatas arrived early and was very professional. He has done so far 4 decks, and I don?t have any complain. He always give the extra mile!
Very professional, responsive and transparent on the project we hired them to complete. Overall, we were very pleased with both the experience and final product.
Universal J&S did and excellent job repairing the steps on my Deck/porch at a much reasonable price than the other two establishments that provided me estimates. Not only that, but the steps on my deck look a lot nicer than how it was originally designed. Would do businesses again.Leah
Very professional and built a very nice, small front porch.
I highly recommend this company for all your home repair needs! They were fast, clean, respectful and addressed all of our needs and concerns. Willing to work with our budget and recommendations and still making it look great, affordable and beautiful! I’m so in love with my 3 season porch and the extra side job of putting up a chalkboard slate in our kitchen! I will definitely call them again for any future projects! Will be telling all my friends about them, for sure!
