Get matched with top building site preparation and clearing pros in Derry, NH

"Jared did an amazing job and was very thorough in his work. He prepared the site work for a retaining wall behind a newly installed pool and the attention to details in where he placed the drainage was perfect. The following week we had a tremendous amount of rain and it kept all that water well away from the pool. Took a lot of pride in the work he did for us and can not wait to work with him again on our next project!"

"David built a stone wall and beautiful stone and limestone stairs for us years ago. Now he and Nathan did a stone walkway set in concrete. Their work then and now is just impecable. The skill and artistry is amazing. Itâ s clear they take pride in their work. They are extremely easy to work with and come and do what they promise. A rare find. Wouldnâ t think of using anyone else."

"If in need of excavation services again they will be my first choice"

"They showed up as promised and got right to work! They worked quickly and efficiently and were done in no time at all. We're a senior, disabled couple, and the great job they did truly helped us. We will gladly call them again and give them glowing recommendations whenever we can. Great guys, great job!"

"We interviewed 3 contractors. The quotes were close, but we felt more confident with Shawn's vision. We had a very large area to excavate and landscape. We had many trees removed and close to some wetland area which could not be disturbed. Shawn had a vision and we let him run with it. Timing wise he finished up just prior to the start of many long periods of rain. It was a very big project, and he mostly worked alone. He brought in some help for top soil raking and prep for the hydro seed. Shawn is a good guy. Very pleased with his work and glad he's out there doing the this work. We love the yard, it came out great."

"We had an amazing experience with Twin Timber! They completed a full kitchen remodel for us, and we couldn’t be happier with the results. From start to finish, they were professional, reliable, and paid incredible attention to every detail. The quality of their craftsmanship is outstanding, and they made the entire process smooth and stress-free. Our kitchen turned out even better than we imagined, and we’ve received so many compliments on it. We highly recommend Twin Timber to anyone looking for a beautiful, high-quality renovation. Thank you for making our dream kitchen a reality!"

"We hiredTseranos Construction to add an addition to our home, mudroom, garage with primary suite above. I would highly recommend this company, work was completed on time and we were very happy with quality of work. The owner was always available to answer questions and help us through the construction process."

"Highly recommend! Easy, timely, thorough and cost effective. Will definitely call on Ethan again for additional projects."
