"I thought I'd provide a 6-month update on the work performed by Coen. In short, we selected them to do some minor renovations to the bedroom and living room - ceiling repair and electrical work - and then paint the entire interior of the unit. It was horrible. We settled a reduced fee and went our separate ways. Since then, we've had to remove the work they did and repaint the entire hallway, bathroom, and kitchen due to paint peeling. Based on the prior experience and having visited during the renovation, they didn't prep a single thing - the walls definitely needed that even prior to other work starting. The new contractors very clearly were able to show how the surfaces weren't prepared at all for paint related to dust under all of the layers from the drywall and other construction work they did. Not a single apology or visit from the owners to date. Don't waste your time, money, or effort on this company whatsoever."

FAQs for addition to existing structure building service projects in Southborough, MA
Building an in-law suite takes between two and seven months. Converting an existing basement, attic, or room can be done in about two months. Constructing a new addition or detached suite often takes four to five months for construction, plus one to two months for permits. The bigger the suite, the longer it will take.
Yes, you can build an in-law suite in your backyard if you meet local building codes and zoning regulations. An in-law suite often occupies 300 to 800 square feet. Be sure to follow size restrictions, utility separations, and entrance requirements. Hiring a qualified contractor ensures you meet all regulatory requirements because they can pull permits, double-check local code, and gather other skilled pros to work on your suite.
An in-law suite is a self-contained living space attached to—or detached from—your main home. Expect a bedroom, full bath, and a kitchenette or compact living area. The setup gives relatives privacy, doubles as a potential rental, and can lift your property value. To qualify as a legal dwelling, the suite must meet local building codes and zoning rules.
