Services Deck & Patio Installation

Dave and his crew did a great job installing our roof and trim in Hampstead NH. They left our yard totally clean. Highly recommended!!

Dave and his crew did a great job building our 2,000sf in-law. I was the General Contractor, but I can honestly say that Dave was one of the main reasons we finished this project on time and under budget. I have given Dave’s contact information to a lot of people since our project.

David came out to check out a leak that I had around my furnace chimney. He went over and above to inspect it and did a professional repair to replace the damaged flashing that the roofing company overlooked. I highly recommend him for home repairs

Final We hired the Clemens group to vinyl side our house and couldn’t have been more pleased with the outcome. The professionalism of the employees was top notch. I will gladly hire the Clemens group again for any projects that I have.

Communication was on point… they were able to give me a clear and concise outlines of the pricing of the two projects I needed done, which was a roof and a deck estimations were on point and the timeline was right where he said it would be could not be happier with the outcome will be using them for any projects going forward!!!

Had an urgent need for roof repair, but decided shingles were old enough that a full replacement was the better long-term route. David was great to work with. Very professional, and was available to start quickly. Supplies were delivered within a few days, and his team was done in 1 day. Couldn't be happier. Have recommended Clemens Group to several others in need of contract work.

I enjoyed the pleasure doing business with David and his crew in all they were so nice. The pricing for my roof was not as steep as I thought and I went shopping around I can honestly say I'd recommend his serves to friends and family who need their roof renovated or done very positive crew and easy going to speak to.

I met with Dave the owner of Clemens Group and what a classy, personable, and honest guy! So happy to have found them. If you’re looking for the right people for the job look no further. Highly recommend!

The Clemens group was the perfect group to have help us renovate our home. They made replacing our roof a breeze. The whole job was completed in one day. The next day they were able to build us a small deck off our back door. We love the new space and would highly recommend these guys for any projects you want to complete. Thanks guys.

Great service and expectations set, was able to add expertise in multiples areas and trades when it came to the renovations. Highly recommend for any renovation or build soup to nuts!

The Clemens Group did a superb job replacing my roof. They were easy to communicate with, efficient, and cleaned up well afterwards. When I noticed a couple of things that needed attention, they were very responsive and truly aimed to make the customer (me) happy. My new roof looks great and I would highly recommend them. The shingles I chose are Tamko Titan XT (Thunderstorm)

David and his crew do outstanding work! They give 100% into every project and I wouldn’t choose any other company! Highly recommend

I've collaborated on several large residential renovations with the clemens group. Dave and the Clemens team as a whole has a level of integrity that is extremely rare in today's construction labor market. Over the course of our additions and renovations, they've faced any challenge head on, excuse free, and promptly. Human error is common in this industry, integrity, professionalism, and craftsmanship are rare. For this reason we will continue to work with the Clemens Group on future residential and commercial construction projects.

The Clemens group just completed our new deck and patio, and we could not be happier. Dave and his team started our project when we were in Ireland. Despite the time change and fact that we were thousands of miles away Dave kept us informed every step of the way! Dave (and his team) were consistently honest and transparent about our options and cost. They were considerate of our budget and vision. From the start, we knew Dave was somebody we could trust and depend on. He and his team exceeded our expectations. We will definitely be calling Dave back for future projects.

Recent high winds resulted in blow-offs to a 7 foot section of our roof. Dave from The Clemens Group returned my call within 24 hours, and within 48 hours, the repair was complete. I highly recommend the Clemen’s Group for their responsiveness and commitment to delivering a 5-star customer experience.

We set an appointment for an estimate. He was on time, clean, friendly and precise. We agreed on a price and set a date. The men showed up on time, did all the carpentry work agreed upon cleaned their work area and billed me for the price we had agreed upon. Everything went smoothly, they explained everything concisely and followed up the following day to ensure that I was happy

David and his team replaced my roof. They were experts in their field, professional to deal with and very high integrity. The quality of their work was top notch and extremely high quality. I would highly recommend using The Clemens Group.

I have worked with other contractors and found the Clemens Group to be the most reliable and dependable. His quality of work was excellent as well as his follow up. Dave was great to work with and I plan on using him for future projects.
