"Situation resolved!!!! This started off as a little bit of water in the corner of the basement but escalated very quickly with the snow melt. Sean was here the same day I called to assess the situation and began work shortly after. They had to chop up the entire perimeter of the basement floor to install the french drains. This is definitely messy work and they never left a mess behind. All the guys were great and the work was well done and in a very timely manor. HUGE amount of stress has been lifted and thank you to Century Masonry and Waterproofing for making the process relatively painless."

"I had a previous company come in to waterproof my basement and they charged me more than Once and Done and did a horrendous job. They didn't do it correctly and more mold grew. Once and down came in, tore out the previous work and put in their system and my basement is completely dry even during the wettest months & completely mold-free. They gave excellent customer service and priced the job VERY reasonably. This is an honest company and do super work. I would give them 10 stars if I could."

"We interviewed several waterproofing companies for installing a French Drain. We are in NE Philly where the water table is so bad. We get water in our basement with nearly every major rainstorm. After 2 storms dumped 7" in 3 hours and another that dumped 4" 2 days later, we'd had enough after 13 years. Ryan came out and did an inspection and showed us what our basement needed and what Dry Tech's installation would do. He answered a lot of questions and did great follow up with us, without being pushy on hiring his company. After meeting with other contractors, we gave them the job. The workers were thorough, courteous and professional. They took all the steps needed to cover and protect our things that were in the basement and cleaned up everything afterwards. The job took 2 days. While I can't YET state how great the drain works, I'm actually looking forward to the next big rainstorm"

"Full waterproofing of the basement in our 95 year old house, including demolition of walls and shelves/cabinets/sinks and plumbing. Additional service of adding a footing to the basement walls. All the work took three days. Excellent work and looks great, though a bit costly."

"John & his crew did an excellent job repairing my foundation & also cleaned & painted using epoxy on my basement walls...no more musty smell! Without me asking, John did other small repairs unrelated to what I hired him for. John & his men did a very neat job in a timely fashion. I would highly recommend him."

Basement Waterproofing questions, answered by experts

Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.

A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can’t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it’s legal to do so.

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.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. The chances of mold developing depend on several factors, including the severity of the damage and how quickly the area is cleaned and dried. To prevent mold, you must act quickly—ideally within the first 24 hours. Clean up all water and thoroughly dry the affected area. If the damage is extensive, you were unable to address it immediately, or you suspect mold has already started to grow, it is best to assume it is present and hire a professional mold inspector or removal expert to assess the situation.

Make sure you're calling in the right expert to help repair and/or clean your crawl space. A serious issue may require multiple experts that include a local mold remediation pro, an HVAC pro, a foundation pro, and a plumber. You should also consider using a nearby junk removal service to avoid handling debris that could be covered in mold, fungi, rot, or asbestos.
