Featured Reviews for ADU Contractors in Londonderry

Crossroads Contracting, LLC
ADU Contractors in Londonderry
Average rating: 5 out of 5 starsDecember 15, 2016
“After a year of searching for the right people to replace our attached carport we were happy to find Crossroads Contracting. From the first meeting with the project manager ( Nick), we could see that this was going to be a positive experience. Nick worked with us to design something that was both structurally superior and surprisingly affordable. In fact, we were so impressed with the workmanship that we hired them again a few months later to replace our porch. If you are looking for quality work at a competitive price , then look no further. Our thanks to Nick, Crystal, Johnny, Shaun, Barry & Jim for increasing both the comfort level and the value of our home. We know who we will be calling for any future projects!”
Dream Builderz
ADU Contractors in Londonderry
Average rating: 5 out of 5 starsDecember 17, 2014
“I was unexpectedly faced with a significant construction project as a result of wear and tear and water damage. the entire front porchway and second floor deck as well as a retaining wall needed immediate work. I contacted Mr. LaPuma who came out and assessed the situation. He gave me a true estimate that was financially competitive and accurate as to time. He was true to his word and started the job, after full permitting, on the day he had proposed and finished the job within one day of his original projection. it is rare to find a true professional in the construction trades --- Dream Builderz and Mr. LaPuma are such professionals. Reliable, quality work done with precision and pride.”
Matriarch Construction
ADU Contractors in Londonderry
Average rating: 5 out of 5 starsDecember 1, 2023
“Kitchen remodel and 2 Bathroom remodels I had the pleasure of working with Matriarch Construction to remodel my kitchen and 2 bathrooms and they exceeded our expectations. "Received daily emails regarding progress and/or upcoming information/meetings. Quick response/resolution to any concerns/changes requested. Clear breakdown of allowances/estimates, including any change orders. Friendly, and reliable from start to finish. Which is a huge comfort for a family having work done in their home - especially with young kids. Great follow through with open items at the end of the job. Did not have any issues getting them to come back to finish even the smallest items. Outstanding service. Thank you Matriarch!”

ADU Contractors in Londonderry
Average rating: 5 out of 5 starsSeptember 26, 2013
“Joe Fournier did some great architectual design work on two large projects we did. A large remodel on one property and an almost complete rebuild on a second property. Joe acted as GC on the second job and did a wonderful job keeping things moving, helping us get good decisions made in a timely fashion and working closely with all the trades to ensure the work was coordinated and of high quality. The transformations to our properties were hugely successful and Joe was instrumental in helping us get to a place where the homes work so much better for our lifestyle. Highly recommend Joe's work (and already have several times).”

“Dave is an excellent craftsmen, and intelligent builder. He returns calls on time, texts daily, and his pricing and work contract are very transparent We originally needed a window replaced, but the project morphed into a much larger project because of carpenter ants. He ended up having to replace all the shingling on one side of our house. Dave was very honest and clear on how the project escalated, what new costs were and gave us different options for budget and solutions. He encouraged us to go with a bit higher quality in materials, and we are really thankful we did the job right. It was late January and he and his fellow builder showed up in 10 degree weather for a week. His coworker was a pleasure to chat with every day, With 3 children at home, it’s important to feel comfortable with workers and I fully trust Dave and his Team. He always was meticulous with clean up. My one suggestion would be to understand his payment plan. We gave him a down payment and then wrote fairly substantial checks weekly. I felt like I was not always prepared with money in the bank to cover that week’s installments. I would prefer one deposit down and final payment at end but this was our only issue. His knowledge and expertise were worth it,! We were very pleased with the end result and quality of work and highly recommend him!”

“Nick is currently helping me design a 'tiny home' in Southern California. In the past months he has drafted several designs that are typically more and more amazing as we work through it.

“I used Clear Cut Design for a wet bar in our dining room and built in cabinets in our powder room. They both came out beautiful. His work is amazing quality and excellent craftsmanship. I appreciate his attention to detail and helpful feedback when I had questions while designing the built ins. He was extremely professional and personable throughout the entire experience. I would absolutely hire him again for my own home or my interior design clients.”

An accessory dwelling unit (ADU) is a separate living space that can be added to your property. It functions as an additional dwelling on the same land where your main home is located. ADUs have their own amenities and entrance, providing a self-contained living area. Unlike a traditional home, an ADU cannot be sold separately and is considered part of the same property.

ADUs are subject to specific zoning regulations and building codes in Londonderry. These regulations determine where and how an ADU can be constructed, ensuring compliance with local laws and requirements. It’s important to consult with local authorities or a professional contractor who is familiar with ADU regulations in your area to understand the specific legal differences and ensure your ADU meets all necessary criteria.

Consider these options for cost-effective ADU:
  1. Prefabricated ADUs: Affordable and easy to assemble, they’re a practical choice. Many prefab ADUs cost under $100,000.
  2. Traditional Construction: Work with an ADU contractor to find budget-friendly options and make smart choices.
Tips for cost-effective ADU construction:
  1. Define your needs: Determine the purpose of your ADU, whether it’s for family, rental income, or a home office.
  2. Consult a contractor in Londonderry: Their expertise can help with cost-effective materials, designs, and planning.
  3. Prefabricated components: Consider using prefabricated elements like cabinets or bathroom fixtures to save time and money.
  4. Explore financing options: Look for ADU-specific loans or programs to help cover costs.
Ensure compliance with local regulations and seek professional advice. A knowledgeable contractor can make the process smoother and cost-effective.
