"All Under One Roof did an amazing job with my roof replacement. My roof was leaking for the last couple months so I decided before winter to replace. When they were replacing it I was informed and shown pictures of how bad the damage was. The roof has extensive rot in many areas. All Under went above and beyond and cut out all the old rot and replaced. They went into great detail to show me the rot and how it was leaking for years, but not into the interior of the house. I am so happy at how it came out and will recommend All Under One Roof to all my friends."

"Keith Jordan and his crew did a great job installing our siding. They paid attention to all the little details. Keith went above and beyond to help fix a problem that was discovered during installation. Would definitely recommend for future jobs."

"The siding and trim project planning, material delivery, equipment set-up, daily site clean-up and siding/trim installation were all very professional. The crew's attention to detail and craftsmanship were outstanding. The project was completed on time and on budget. I highly recommend Merrill's Home Repair & Renovations."

"Josh the owner of the New Hampshire location came to my house on time when the appt was made. He gave me a quote with range. Within 2 weeks he and his siding installer came and did the work I needed and completed it in one day. I had an invoice within 1-2 days and the price was a little lower than the estimate. They did a good job and cleaned up. Josh is a great communicator and always follows up. I would recommend his company for at least what I needed which was removing some siding and replace some waterproofing with improved products and techniques and reapply the existing 27 yr old siding."

"We bought our first home this year and absolutely love it, but we quickly learned it needed more TLC than we realized. We could see rot on our exterior trim and clapboards, plus a missing gable vent. From the very beginning, Shawn impressed us. His estimate was incredibly thorough, and it was clear he’s a true professional. As new homeowners, we felt confident putting our home in his hands. We are so fortunate we hired him. Shawn showed up early, worked late, and demonstrated meticulous attention to detail in everything he did. When we discovered the rot was far more extensive than we thought, he never made us feel stressed or overwhelmed—he walked us through our options, offered solutions, and helped us make the right decisions for our home. The quality of his work speaks for itself, but just as important, his communication, reliability, and integrity made the experience exceptional. We will be working with Shawn for all of our home’s needs. We actually missed him when he left !"

Customers say: Quality work

"My wife and I chose BG Construction to stain the exterior of our cabin and also the interior of our covered deck, to include railings and all landscaping ties. We knew there would be extensive scraping and caulking and we also feared there would be unforeseen problems that would require carpentry and other construction. WE received a complete walk around and possible problems were pointed out to us. An accurate estimate was given, barring of course, unforeseen work. Bill Gray and his associates, Bobbie and Frank, were nothing short of fantastic! They are courteous, extremely friendly, and about the hardest workers we have seen in a long time. They became part of our family during their time here. If you are looking for a full service outfit that are capable of not only painting but fixing things too, you can't do better. Bill and his crew are craftsmen. Choosing BG Construction was one of the best investments we have made concerning our home. Eric/Patt"
