"Fast Estimate , had many estimates from other companies and Waterproofing One was the best price for Us , Joe was very confident and knowledgeable and gave Us good suggestions for our leaking basement, the crew that installed the French drain inside were great, install looks very professional. I figured we’d have a mess to clean up after the install understandably. But wow they did an incredible job cleaning up afterwards. Not a speck, they even spent time cleaning off the driveway and front lawn. We have been through one major rain storm since the install and not a drip of water. So far so good , we are getting an expected 3” in the next 24 hours and it’s a relief to know I don’t have to stress about rain storms anymore!"

"Zoom Drain was great !! Everything was explained by Rob on Friday when he came out. Service was provided the day we called due to hearing gurgleing in the kitchen sink when the toilet was flushed. Rob found a blockage in the drain box outside our house which he cleared. On Sunday we found that we were still having some brief water backup into our basement laundry tub when the bathroom toilet was flushed, Kyle came out that afternoon and determined that part of the issue was that the Municipal Sanitary Drain was running slow. Kyle even pulled the Municipal Manhole cover in the street to confirm that the water level was much higher than expected. He spent the time to make sure our drain was as clear as possible and even called our local borough office to inform them that the Municipal drain seemed to have a blockage. We saw a truck on our street this morning and were informed that a large grease plug was found in the municipal drain on the street next to ours. They cleared it on Sunday night and were checking the line upstream from where the plug was to make sure everything was clear. Thank You Kyle. Thank you Zoom Drain Norristown. Highly recommended !!"

"We had a great experience hiring '58 Foundations to waterproof our basement! Lon was our salesperson, and he came and explained the work that would be necessary to ensure that water would never flood our basement again. We appreciated him taking the time to explain how the whole process worked, and providing us with the option to finance the project to make it affordable for us. We had Brett Boyles and his crew, John and Clarence, come to do the work, and they did a fantastic job! Brett even came to show us the progress in the middle of the project and explained every detail of the work that was being done. He was very professional and we appreciated how he gave us peace of mind about everything once the project was completed. I would highly recommend '58 Foundations for anything basement-related. We appreciate your business - thank you!"

Basement Waterproofing FAQs, answered by experts

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.

The best way to ensure the ground next to your home’s foundation drains properly is to divert water away from it as much as possible. While a flood wall can stop water from entering the house, gutters and spouts can help direct rainwater and melting snow away from the foundation. Keep your gutters as clear as possible from dead leaves and other yard debris so they can effectively divert water from your house. Add extenders to the spouts so the water runs out and away from your home, not into the surrounding soil.

Most people consider a French drain to be one of the most effective solutions for foundation leaks, but it’s not always a standalone solution. French drains will help keep water away from your foundation to reduce the risk of leaking and structural damage from soil expansion, but depending on your foundation type and location, you might need other systems or techniques—like soil gradation and gutter and leader installation—to resolve the underlying problem.

Preventing future basement flooding often involves installing sump pumps, improving drainage, sealing foundation cracks, and maintaining gutters. Costs vary, but preventive measures can range from a few hundred to several thousand dollars, depending on the solutions chosen. Investing in prevention can save you money on future flooded basement cleanup costs and repairs.

Encapsulation can take the place of crawl space vents since it protects the area from moisture and air all year round. Determining whether you should open or close crawl space vents can be complicated since it often depends on the weather and humidity. Skip this step by investing in crawl space encapsulation whenever possible.
