"Tyrell did an excellent job correcting the mistakeS of the people who installed my basement waterproofing equipment. There was a terrible rotten egg smell and that's gone now. Tyrell cleaned up after himself, if any water spilled he made sure to vacuum it up and to dispose of everything in the proper place."

We offer 15+ years of experience in the Foundation and Basement Waterproofing industry. We've established a solid reputation serving residential homes in the greater Philadelphia and surrounding areas. We are committed to providing a personalized service for each individual project we take on. We look forward to building strong, long-term relationships with our clients..

"This company customer service skills and communication are horrid. I had no problem scheduling an appt for someone to sell me on their business but they day the work was to be done, I had to call them 5x for ETA checks on their techs. They were supposed to arrive between 9-9:30am and did not arrive until 1:15pm. Each time I called about the tech ETA, I was told by the receptionist that they would check and call me right back, they never did. The 5th time the receptionist said the supervisor of the techs said they were dispatched to my location early that morning, but he does not know where they are or why they did not show up. The receptionist called back later to say the techs should arrive by 12pm but they did not arrive until 1:15pm. When the techs arrived, I found that their supervisor told them to do a job prior to coming to my location. I was supposed to receive a lifetime warranty for the work done and after 4 calls I still have not received it. Poor customer service."

"The job inside was done. However the drainage put in outside has turned our yard into a swimming pool. We once had a pipe draining to the creek and this was a perfect solution to the rains/weather. These guys came in and put a round small cylinder well. Water pumps up into our yard turning it into a swamp. Called them to come and see the problem they created. Their response $2900 to fix THEIR DAMAGE. I WOULD NEVER RECCOMEND THIS COMPANY!!"

Basement Waterproofing questions, answered by experts

Anything having to do with the structure of your home, such as raising the ceiling, is usually the most expensive part of finishing a basement. Another project component that could be a surprisingly high expense is adding an exterior entrance. 

The cost of a walkout basement can be anywhere from $5,000 to $35,000.

If there is standing liquid on your concrete, remove it before attempting any of the above cleaning methods. For small amounts of water, use rags, a bucket, and a mop. For larger areas of liquid, lay down cat litter or baking soda to soak up the water first. If you have extremely large pools of water sitting on your concrete, break out the wet vac and get to work.

To ensure your basement walls are waterproof, it's crucial to address any existing moisture issues before finishing. Inspect for signs of water seepage, such as dampness or discoloration, and repair any leaks or cracks. Install a vapor barrier to prevent moisture from penetrating the walls, and consider waterproofing paints or coatings.

Proper drainage systems, such as interior or exterior waterproofing, can also be beneficial.

Crawl space encapsulation can make repairs more complicated, particularly if you have plumbing or wiring surrounding your crawl space area. Additionally, some home designs benefit from the additional airflow that crawl spaces with vents provide. Vents are no longer an option after encapsulation. Always talk to your crawl space contractor to ensure the pros outweigh the cons before investing in the installation.

It depends on what caused your basement flooding, the extent of the problem, and the risk of the flood continuing. If your flood is coming from a septic system or sewer line, breathing in the sewer gasses can be dangerous, so you should vacate. If the flood occurs from an ongoing natural disaster, relocating to a safe area might be wise. If you just have a plumbing leak or rainwater coming in, you can likely stay in the house if you don’t have electrical lines down there, but make sure you call in professionals to fix the issue immediately.
