Get matched with top concrete mudjacking pros in Derry, 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!"

"They did a fantastic job! We have had driving rain since the installation and our basement is bone dry. They came on time, were very polite and I'm very happy with the fast train system they installed."

"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."

"Our house's cinder block foundation is leaky in key spots and the recent monsoons meant some water got inside the house. Sean came out to inspect and quote. The plan was to remove a French drain to dig a trench, waterproof the foundation, and then put the French drain back. The price was reasonable plus he guarantees his work so that made us feel comfortable. His crew led by Hector, started work a week later by moving the French drain and digging a 5-6' deep trench around the offending area. They stuccoed and then waterproofed the foundation. When a couple of issues came up (as they always seem to in-house repair), Sean came over, assessed, and explained the situation and we agreed on the best way to proceed... and they carried on without missing a beat. Post-job care was good too as a few days after they were done, we had an issue with settling which caused the drain pipe to disconnect from the French drain. Sean and Hector came out to take a look and they put it right that day."

"Great! Joe was professional, prepared, and very knowledgeable on his trade."

"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!"

"Stavros and his team were excellent professionals. They scheduled an inspection of a crack in a concrete retaining wall, evaluated my foundation, and were able to schedule the repair within the same week! I appreciated that they both kept me well informed of the process, took pictures of their work, and gave me recommendations for a longer term solution. They were very respectful of my property (I noticed they were even careful not to track dirt into my house and flattened the earth where they had to dig to make the repair). They were also very prompt, worked hard, and made sure that everything was a great experience."

"They were very professional. removed and rebuilt 2 chimneys for me on a 3 family and 2 family. Highly recommended and would use again!"

"Have recommended them repeatedly. Estimates usually on the low side...but there are always changes as work progresses, so that is to be expected. Very helpful, picked things i had ordered up. Reliable and trustworthy.

"Outstanding work, and very nice to work with. Would highly recommend !!"
