"The project went great; I'm very happy with the final product. It lines up exactly with what I was looking for at the start of the project and looks better than I could have planned because of some great design suggestions from Wagner Home Renovation along the way. We ended up creating two separate closets from the previous closet incorporating some previously unused space in the condo as well. Both closets are accessed through very nice double doors. The laundry closet and general/clothes closet both look great. Wagner Home Renovation used high quality repurposed wood from a previous project and black iron rods to give the general/clothes closet great character. All of the work was very well done, and blends into the existing paint and trim-work so well, you can't even tell any work has been done. As an example, they added a wooden keystone at the enlarged entranceway near the new closets that was a very nice touch and feels like it was always there. They were able to save me money throughout the project by offering to use repurposed wood from previous projects that was often better quality than what would normally be used. Wagner Home Renovation does high-quality work and has a genuine interest in how well the end result turns out. They have a great attention for detail, offer great design ideas and options, and are responsive, honest, budget-conscious, flexible, reliable and easy to work with. I highly recommend them."

"This was our second time hiring Norman Builders and the experience was just as amazing as the first! Ryan and his team remodeled our kitchen in 2018 and we knew right away that we wanted them back to do our master bathroom. The communication was seamless and the quality of work done by Brian, Kevin, Lance and all of the plumbers and electricians was top notch! Everyone was amazing especially when dealing with all of my questions and design ideas, including rearranging the layout and plumbing to accommodate my request for a large picture window with a soaker tub in front of it and having multiple shower heads that all function independently as well as together! The heated floors are also a favorite as well as our closet that Brian designed! We are so thrilled with the the final results and our bathroom is now a sanctuary that I never want to leave! Thank you Norman Builders!!"

"Chris Ayotte went up and beyond to provide the perfect solution to our kitchen addition. His efforts and constant communication helped us through the process. He is a man of his word and a very kind gentleman. His prices are fair and he's a hard worker. I'd hire him in the future always."

"I would not hesitate for a second hiring Horsman Builders for any of my house projects or remodel, in fact that is what I will do from now on. I was nervous starting a project having to handle things on my own but Tim made me comfortable with a detailed estimate, answered all my questions, kept me informed about the work, the site was always clean and the result is awesome, my neighbor was commenting on how great it is just checking it out from a window. Fair price, excellent quality and great customer service. A+"

"It went great. Chris built our custom home exactly to our specifications. We lived out of state for the entire build. Chris maintained open lines of communication with us so that we always knew what was going on. His work is impeccable. His attention to detail resulted in our dream home being exactly what we expected when we hired him. His group of subcontractors were great throughout the entire process. I have not spoken to anyone in the area that has anything but praise for Chris and his work ethic. Chris came highly recommended by a number of people and I would carry on that tradition and recommend Chris Johnson for any construction project from a remodel to building a new home from the ground up. I would certainly use Chris again for any future construction needs."

Customers say: Quick response

"Because we were going away for an extended time, and insulation work by others had to be completed first, we had to schedule drywall workday NH Projects under a rather tight time frame. Despite uncooperative weather (lots of rain slowing the drying time), they managed to get everything done as needed, working around other scheduled work they had. They were prompt, professional, and a pleasure to interact with, in addition to doing excellent work."

FAQs for addition and remodeling projects in Portsmouth, NH

The proper sequence of a kitchen installation starts with laying the foundation and structural framework. From there, you need to establish utilities like plumbing, wiring, and gas lines, then install cabinetry and countertops, and finally finish with flooring, painting, tile backsplashes, and lighting. A professional kitchen installation contractor can coordinate each component of your project to minimize the timeline and maximize resources.
