Get matched with top concrete mudjacking pros in Sunapee, NH

"Just finished a visit with Foreman Doug and his crew, Devin, Sean, and Mason. Waterproofing the basement and super sound and solid work! Doug was professional and very good at keeping me in the loop with the project over the 3 day visit, and created a solid system that we are confident will keep water out of the basement forever. Above and beyond as well with problem solving when having to find solutions to fit our basement layout, all with a solid financing option/great price and 5 year warranty/ yearly inspection plan. If you are stuck with water in your basement, get Groundworks working for you ASAP!"

As a highly skilled framer and carpenter with eight years of dedicated masonry experience, I bring a rare and comprehensive understanding of structural development to every project. My background blends the precision of finish carpentry and the durability of robust framing with an extensive mastery of concrete, stone, and brickwork. This unique dual expertise allows me to seamlessly bridge the gap between foundational masonry and structural woodwork, ensuring structural integrity, exceptional craftsmanship, and efficient workflow management from the ground up.

"I recently had my shingle roof replaced and I?m very happy with the results. The team was professional, punctual, and completed the job efficiently. The quality of the work is excellent, and the new roof looks great. They kept the work area clean and communicated well throughout the process. I would definitely recommend them to anyone needing a roof replacement."

"We have had an intermittant water problem in our basement primarily when it rains heavily in the Winter.
I was very happy with the quick response from Mike Sears when we initially called to ask about repairing a water leak problem in our basement.  Mike explained how his proposed solution would work to alleviate the water problem. 
Mike left us with a detailed estimate and informational materials about the proposed repair.  He also explained what wasn't included in the job such as tearing out the current sheetrock, insulation and framing from the wall.  I did  this part of the work and the reconstruction after the drain had been installed.
We spoke to Mike a few days later, agreed to the price and set a date for the repair.
On the scheduled date, two of Mikes employees arrived on time and began to prep for the repair.  They did a good job of hanging plastic sheeting around their work area so that the dirt and dust would not get into the rest of the basement.
We had discovered a crack in the basement wall which wasn't visible when the original estimate was given.  Scott Lee gave  us a written estimate to repair it with carbon-fiber cloth and sealant.  While this was an unexpected expense, there was no reason to put in a drain and leave a crack in the wall.
Taking out a basement floor with a jackhammer and installing a drain is a hard, dirty job.  Scott and his co-worker completed this job in about 6 1/2 hours including the additional work for the wall crack.
They did a good job of cleaning up the old concrete and all working materials 
Scott explained how the pump would work when the water table under the house rose.  
My only issue with quality was the uneven concrete finish work on the basement floor above the drain.  Because this was leveled by hand, there is a somewhat noticeable depression in this area of the floor.
Overall, I am happy with the work and looking forward to a dry basement when the rains come this spring.

"St John Enterprise provided a professional service at an affordable price. Their communication and customer skills are excellent. They showed up on time and worked efficiently to deliver high quality work. The patio and front step have received many compliments, and truly exceeded my expectations. I will definitely hire these guys again any time I need concrete work done!"

"job completed as stated. On time, thorough and no mess left behind. We have had a few rain storms since the repair was completed and the crack did not show any signs of leaking. thank you"

"Price seemed a bit high for such a small job, but they could do it the same day. They did come down on the price when I agreed to get it done today. However since then Iâ ve noticed that the mortar in the patched area is nearly flush with the brick face, whereas the other mortar (the whole rest of the wall) is set quite deep in. The patched area really stands out as a patch. They didnâ t match the mortar depth to the rest of the wall. Iâ ve repainted the entire hearth to see if that helps, but itâ s still quite noticeable. Not impressed. Lesson learned."
