The Design-Build Remodeler That Southern NH and Northeastern MA Trust

At Blackdog Design/Build/Remodel, we understand that starting a major remodeling project is a big decision. Whether you are thinking about an Accessory Dwelling Unit (ADU), planning an exterior remodel, or wondering about aging-in-place renovations, the experience can feel overwhelming without a well-defined process and a trusted guide. Homeowners in Southern NH and Northeastern MA often come to us looking for a remodeler who brings structure, organization,  and accountability to a time-tested process.

As a true design/build remodeler, we manage design, budgeting, and construction under one roof, keeping decisions aligned and expectations clear from the beginning. With decades of experience remodeling homes in towns like Salem, NH, Andover, MA, and across the North Shore, we have refined a structured approach that prioritizes transparency, communication, and thoughtful planning.

The same core remodeling process guides every project we take on, whether it is a kitchen remodel, bathroom renovation, home addition, whole-house transformation, or something else. No matter the type of remodel, your project and your experience as our client come first. We invite you to explore our portfolio and see what is possible when you partner with one of the most trusted design/build remodelers in Southern NH and Northeastern MA.

Our End-to-End Design/Build Remodeling Services

Blackdog Design/Build/Remodel provides complete design/build remodeling services across our service area, including towns like Salem, NH, Andover, MA, and communities throughout the North Shore. From initial planning through design, construction, and long-term support, we manage every phase of your project.

As a true design/build remodeler, Blackdog Design/Build/Remodel does not rely on outside firms for critical parts of the process. Designers, project managers, lead carpenters, and production staff all work together under one roof, keeping decisions aligned and responsibilities clearly defined. This integrated structure reduces handoffs, improves coordination, and creates a more organized remodeling experience from start to finish.

During construction, your dedicated project team from Blackdog Design/Build/Remodel remains responsible for your home until the work is complete. Systems are in place to manage schedules, protect your space, and maintain consistent communication throughout the project. After construction is finished, we continue to stand behind our work with an industry-leading 3-year warranty and a dedicated warranty specialist. You can take a look at our cost guide to see what your project might cost and start planning. 

By managing every phase internally and remaining accountable long after construction ends, we give you a remodeling experience built on organization, transparency, and long-term reliability.

John B.

"A few years back, my wife advised me that she was weary of cleaning snow and ice from her auto before going to work. This request began my association with Black Dog builders. We asked for a garage to be connected to our farmer's porch via a breezeway. Due to code issues, in order to access our propane tanks, the area had to remain open, and the difference in elevations had to be accounted for. Additionally, the emergency generator panel had to be installed next to the new main switch in the garage. We worked with John Nicholson on the design, and were very happy, with photos of the design and final work appearing below.

Needless to say, we are extremely happy with the superb materials and the workmanship. Oh, yes, my wife remains very, very happy. And, of course, she uses the parking spot closest to the house. I’d have it no other way!"

Very Happy

"I am writing to highly recommend the services of Blackdog Design/Build/Remodeling. As a satisfied customer, I had the opportunity to work with them on our house addition in 2025, designed for single-floor living. Initially, we considered purchasing a new home, but with the current housing market costs being so high, we found that the cost of an addition was more reasonable—and it came without the headaches of moving.

Choosing Blackdog for this project turned out to be one of the best decisions we made. From the very first meeting with our design consultant, Eli, and our project manager, Jason, Blackdog demonstrated exceptional technical expertise and outstanding project management skills. They guided us through every step of the process, ensuring we felt informed and supported throughout. They consistently met all deadlines and, to our pleasant surprise, even managed to keep the project ahead of schedule. The team delivered within the agreed-upon budget while maintaining a high standard of quality in every detail. Beyond their technical capabilities, their communication skills stood out. They provided clear, professional updates daily, keeping us informed of progress and promptly addressing any concerns we raised. I have no reservations in offering Blackdog my highest recommendation for any future projects. Their professionalism, expertise, and dedication make them an invaluable asset to anyone planning a home project."

Highly Recommend

"Blackdog is a top-notch outfit... we had a major renovation at our home. We had never done any work of this magnitude, but from design to renovation never felt uncomfortable or out of touch with where things stood. We felt like we had full control through the whole process, and when things did come up (as they do in any renovation), we were given our options in a transparent way. I would definitely recommend them."

Top-Notch Outfit

"Blackdog renovated our entire first floor, including kitchen, powder room, and entryway. They did a great job, are very responsive, and were very satisfied. Would recommend them."

Would Recommend
Bruce B.

"Blackdog just completed a complete remodel of our master bathroom, including expansion into an adjacent closet. We were extremely pleased with the entire process, including the numerous hours that Melissa spent with us on the optimal layout and design. She carefully listened to all our wishes while providing additional creative ideas and alternatives, and helped us in picking out matching tiles, flooring, etc. There are so many options that it can be overwhelming, but Melissa streamlined it all into a manageable process.
