"Swanick Builders were not consistent with time lines. They would make choices that we as the homeowners should have been consulted on or made. Builders made many mistakes of placement or painting wrong colors from chosen /discussed choices made by us. When talked to about this they would state its a focal point. Level of work has been found to be subpar at best, needing other professionals to come correct. Sub contractors utilized by builders were subpar putting hole in roof . all in all they should not have taken such a large job and we would not be hiring ever again. "

"We just had our roof replaced by Cody and his team. Everything from start to finish was done professionally and skillfully. The roof looks great. His team came in, stripped the old roof off, got the job done quickly and cleaned up every single thing that fell in my yard. Amazing crew. Fantastic job."

Above all, we are watchful of our customers' interests, and make their concerns the basis of our business.

"Once again and with the highest confidence, we hired Russell's Contracting to convert our back entrance into a more open, useful mudroom. As promised, they arrived on time on the expected date and started by sealing off the back entrance for dust. The demolition of the closet was first done, and then the rehab began. I was amazed at the level of detail necessary to make the new mudroom perfect. From fixing the ceiling to installing new walls, taping and sanding, painting, new baseboards, and moving the overhead light, it was fun to watch. Colby was professional, exacting, efficient, clean, and asked all the right questions to ensure we were happy with the result. The new mudroom is exactly what we wanted. In addition, we asked Russell's to help us figure out how to make our open staircase to the second floor safer. Keith, Colby, and Max designed and installed a custom-built, stair-to-ceiling railing system that looks great and provides the necessary safety we were looking for. They also made it removable to accommodate large objects up and down stairs. The amount of time they spent was crazy, and the amount of math they did to ensure it was plumb and solid was above and beyond our expectations. My house was built in 1933, and this railing system looks like it could have been original to the house. It is a masterpiece. Everyone at Russell's Contracting we have met and who has worked on our house has been exceptional. You can stop scrolling for contractors; call Russell's."

"Garrett and his team removed a load bearing wall for us to create a larger living room. The job required demo, architect drawings, inspection, installing LVL beams, adding recessed lights, replacing wood flooring, and drywall. The whole job took about 4-5 weeks. Garrett walked us through the whole process and was always very prompt. If he said he would show up at 9 AM, he would show up at 9 AM. He was also very upfront about our costs?no surprises. Our new living room looks great! I highly recommend Garrett for any renovations!"

"Eric and his subs remodeled the second floor bathroom in our 150 year old home. His team competently addressed long neglected problems by reinforcing the floor joists, replacing and leveling the water damaged subfloor, and providing all new leak free (a new experience for us) plumbing. A beautiful floor to ceiling step-in tile shower was installed along with a new waterproof luxury vinyl floor with a solid wood threshold at the door. A new vanity and toilet completed the room. All new ceiling, wall, and trim paint, too. Eric was in daily communication; We always knew a day ahead who would be here and their arrival time. Eric was just a phone call away when we had a question. Everyone who came to our home was very professional, pleasant, and competent. The work was exceptionally well coordinated and proceeded without interruption from start to on-time finish. We would absolutely hire Eco-Pro for another project and highly recommend Eric and his team."

FAQs for addition to existing structure building service projects in Sanford, ME

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.
