"I required some repairs to the masonry of a granite and cinderblock foundation. James is pleasant, clearly explains the work that he intends to do, and shows the results when finished. He fit my work into his schedule and his crew completed all the repairs within a few days. He and his crew removed all the debris when finished. He also adjusted his schedule to address some additional repairs that were previously unnoticed. I highly recommend James and his company."

"Wow! Unbelievable! If we ever have a water problem again, Pioneer will be the only waterproofing company that we call. We were getting some water in our basement which has a stack-stone foundation and radiant floor heating. We interviewed three companies and were particularly concerned about a solution that would stop the water without compromising the radiant tubes that were in the floor. Initially, Pioneer recommended a baseboard system that would run along the outside of the wall. Upon inspection, Mike Oliveira discussed a traditional drain to sump pump solution. We reiterated our concern about puncturing a tube in the floor and Mike assured us that he and his team would hand chisel potential problem areas to avoid the tubing. Moreover, this solution would save us roughly $2K and give us a lifetime guarantee vs. a 25 year guarantee on the baseboard system. The team showed up on time, cleared a 50' span of concrete by Noon, uncovered two sections of radiant tubing without puncturing the line, installed the moisture barrier, sump pump and new concrete by 4 p.m. They had to drill through a hefty header board to connect the pump line to an existing drainage line that carries water away from home and that was completed by 5:30 p.m. Mike came back in a week and we tested the fix using free-flow from our sprinkler system -- it worked perfectly. Subsequently we've had some consistent spring rain and absolutely no water in the basement. The team (including sales, service, billing, installation) was professional, courteous and available when we had questions. They saved us money, fixed our problem and provided a lifetime guarantee. We're both ecstatic and amazed!"

"First impressions...courteous salesman, but given wrong time frame for work completion.... Customer Service....I called and was given a completion date that was about a month different than the salesman's date....BUT... I was called back by Customer Service (Tiffany) and given a new date that was only a day later than she called.... soooooooooo.... realizing that the weather and the holidays played a role in missing the initial date, I can now say that I'm very happy with the workmanship and professionalism of the whole RamJack New England experience. As it's only been 1 day since the work was done, I'm hopeful that the foundation crack problem has been solved. Time will tell."

"Rick came out to look at the house foundation and told me how to repair it myself. He also recommended how to grade soil so water flows away from the foundation to prevent further damage. I appreciate the time and advice given to me and would absolutely recommend him."

"Cleber was here within an hour of requesting a quote on replacing our front entry stairs. He is professional, started the job on the day he told us, arriving promptly at the time he said to expect him. He assisted us with the selection of materials when we were unsure. Once the work was started, he and his crew were efficient, hardworking, polite, and did a phenomenal job on the stairs. In addition, he repaired part of our walkway. He left the area neat when completed and we could not be happier with the workmanship or the results."
