"The walkway next to my garage foundation had sunk about 4 inches. By mudjacking it was raised to the original level and the rain runs away from the foundation instead of running down the foundation. Great job and they explained the process as it was being done. Very satisfied."

"Groundworks did an excellent job for us. Everyone was so professional and we know we received quality work for a reasonable price. It has been over a year since our waterproofing project in the fall of 2023. At that time we had “nuisance leaks” in our basement but they were becoming more and more problematic. We hired Groundworks to waterproof our basement. The winter spring and especially the summer of 2024 were very wet where we live. We were so proud of our lovely dry basement. It is now the summer of 2025 with lots of rain but there have been no leaks since Groundworks completed our basement project. We are very happy with their work!"

"Very well. Work crew did a good job."

"Not well my carpet is permantely stained with paint, the painters that work for this company are a joke. Chris had to come and fix what they screwed up.

"Contacted Mark and he quickly responded.  We quickly walked through mortgage application and he found a great rate with favorable terms.  Mark assisted us through the entire process, ensuring we were on schedule.  He even helped us find better hazards insurance rate than we found on our own.  Throughout the process, Mark was very responsive, always available and went the extra mile - often swinging by our house to drop off materials.  I would not hesitate to use Mark again.

"I expected that he would do more of an inspection to try and find leaks and crawl space. He could have been a little bit more thorough."

"Mountain top did a great job did a fast job and always left the job site clean"

"Mike, Matt and Glen were very eager and helpful to get our job done right. We were thankful for all their help on choosing the right materials for our project and for not being pushy or using some unscrupulous sales tactics. From the moment we decided to move forward the process went very quickly and painlessly. Luis and his men were the installers and they did an absolutely fabulous job. Their attention to detail was amazing. We are very happy with our decision to move forward with PA Certified Contractors. We appreciated everything!"
