Had a great experience with Main Line Waterproofing. They came to look at some moisture in my basement at my home in Narberth. The tech was very nice and knowledgeable and was totally honest with me. He couldn't find the source of the water and didn't try to push me any remediation.Turns out the moisture was coming from leaks in the ceiling.Great, honest company. Highly recommend.

Main Line Waterproofing recently installed a backup sump pump system and an exterior drain solution for us, and we couldn’t be happier with the results. They added a battery backup to our system for extra protection, which gives us real peace of mind during heavy storms or power outages.They also installed an exterior drain box with a sump pump and ran the discharge line underground exactly as planned. Everything was done neatly and professionally, and they paid close attention to placement and drainage to make sure it would work effectively.The crew was knowledgeable, efficient, and easy to communicate with throughout the process. The whole job was completed smoothly, and we feel much more confident about our drainage system now. Highly recommend Main Line Waterproofing for anyone looking for reliable, quality work.

The workers did a great job and cleaned-up nicely when they were done. The system they installed is great. The walls that they waterproofed came out great. Brian had some good ideas on hooking the condensation drain from my gas furnace into the sump pump drain and on hooking my outside downspout to the sump pump pipe to get the water away from the house. Communication with them was top notch. Their price was great too compared to other estimates. I would highly recommend them to anyone who wants to waterproof their basement.

We recently had Main Line Waterproofing install a pressure relief system in our home in Wayne, and the experience was excellent from start to finish. The team installed 56 linear feet of PRS using our existing pump and discharge, along with a new industrial PVC sump basin.They took the time to properly prepare the space by wire brushing the walls and applying anti-fungal treatment where needed, which gave us a lot of confidence in the quality and longevity of the work.The crew was professional, efficient, and kept everything clean throughout the process. We’re very happy with the results and would definitely recommend Main Line Waterproofing to anyone dealing with water issues in their basement.
