"We recently had our kitchen remodeled and expanded by removing a wall to create an open floor plan. The contractor did an outstanding job. Throughout the renovation, they kept the site immaculately clean, which was much appreciated as we were living in the house at the time. They were always respectful of our space and provided knowledgeable recommendations for suppliers and installers. The entire process was handled professionally, and we are thrilled with the results. Highly recommend!"

We are a licensed and insured residential construction and remodeling company. Our goal is to exceed all of our clients expectations through exceptional customer service and quality craftsmanship. We work with some of the best tradesmen in the industry to deliver a quality finished product. From kitchen and bath remodels to carpentry and painting, we can do it all. Contact us for an estimate on your project today! Check out our instagram for photos and updates @coenconstruction

"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."

"Pierre construction is Awesome!!! If you’re looking to have someone to do your next project, look no further. I spent quite a bit of time interviewing and getting quotes for a major 2 story deck project for my house which included some intense structural improvements to my house as well, since some of the existing columns where in tough shape. I’m so glad that I picked Dave Pierre and his great crew to do this for me! Dave’s price was very reasonable and he was very much on top of all details. He bent over backwards to make sure that I was happy with every step of the project. His crew of over 12 years was also very skilled and often had discussions about challenges to make sure the details where the best that they could be before proceeding on the the next phases. As you can see from the attached video of the 2nd floor, the results are fantastic and I’m enjoying my new space immensely. "

FAQs for addition to existing structure building service projects in Bolton, MA

Yes, you can add a bathroom on a concrete slab, but the crew will need to saw-cut the slab, trench in new supply and drain lines, and then patch the concrete without weakening the foundation. Working with an experienced plumber and concrete pro keeps the structure intact and helps the new bathroom pass inspections.

schedule covers planning, permits, framing, rough-ins, finishes, and punch-list items. 

Larger spaces or extensive plumbing and electrical upgrades can stretch the timeline, while a simple powder-room conversion may wrap up faster. Hiring licensed pros helps keep the schedule on track and the work up to code.

The best location depends on how your family uses the space. An upstairs bath keeps nighttime trips close to the bedrooms, while a first-floor powder room is handy for guests and everyday traffic. 

Think about where plumbing lines already run, how much square footage you can spare, and what layout changes fit your budget. A pro can map out the smartest spot and handle any code hurdles.

With the right planning, you can carve out a bathroom in almost any part of the house. A successful addition requires sufficient space, proper ventilation, and access to plumbing and electrical systems. Structural modifications and adherence to building codes are essential. 

This process demands careful planning and the coordination of specialized professionals who ensure that the new space meets all code requirements and functional needs.

Under specific conditions, adding an extra bedroom can boost home value more than adding a bathroom. Home value is driven by overall configuration, market demand, and functional balance. A new bedroom influences the property’s appeal in different ways, while an additional bathroom enhances living convenience. Evaluating the current layout and market trends determines the optimal choice for maximum value.
