Raz's Construction has 156 building permits behind it, and the work they describe is the structural kind: a $225,000 dormer in Belmont in 2022, a $90,000 Watertown addition in 2021, a Waltham basement turned into office, laundry, bath and entertainment space in 2024. Razmik Banosian's company runs out of Belmont and works Belmont, Waltham and Watertown, moving between two scales. One filing is four bathrooms and four kitchens in a Waltham multi-unit (2023); the next is a run of roofing, siding and window permits in Belmont between $6,400 and $19,400. The typical permit sits near $22,400, and they keep coming — six in 2023, five in 2024, four in 2025. Its Massachusetts home improvement contractor registration is active. The Google reviews are older, five of them between 2011 and 2020, averaging 4.8. Four of the five mention the crew cleaning up behind itself, and three of those also say the work ran on time. A 2020 customer had 18 windows replaced in a single day. In a 2018 review, a homeowner wrote that Raz and his crew had done their two-family roof in Watertown, called them professional, clean and affordable, and had already passed the name to a sister hiring for her own roof. The older accounts fill in the range. A 2014 reviewer credited them with advice on products and insulation on a job that replaced siding and built a new front porch. Another, writing in January 2014 and already booking a third job after a bathroom and a living-and-dining-room project, described a crew that was polite, punctual and meticulous about cleanup. If you are adding a dormer, an addition or a gut bathroom in Belmont, Waltham or Watertown, this is a shop that has pulled permits for that exact work for years. Ask for addresses and photos from jobs finished in the last year or two, and pin the schedule and payment milestones down in the contract before anyone starts.
Raz's Construction replaced 18 windows in one day for us. Great Job. Thanks.
This review is long overdue but I need to post it. Raz and his crew did my two family roof in Watertown last October. I recommended him to my sister who is now hiring to do her roof also. They were very professional, clean and affordable. Everything was on time and they were very professional. I look forward to doing business with him again. I highly recommend him.
Raz's Construction did a great job replacing our siding and building us a new front porch. They gave us great advice as to products and insulation. Their work was very well done, professional and they cleanup thoroughly after. We would recommend them to anyone.
Raz's Construction has completed two jobs for us (bathroom, living room & dining room), and we're hiring him to do a third! He is very responsive, polite and punctual. His team of guys are hard working and clean up after themselves -- very meticulous. Only issue we had was with his electrical subcontractor (who as I understand it wasn't his usual go to guy.) I would strongly recommend Raz!
Great Company! Was on time everyday, cleaned up like they weren't even there after job was done. Prices were very competitive, very nice and friendly people to work with. Will definetly use them in future and would refer to friends.
