"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

Several types of insulation are effective for crawl spaces, with spray foam and rigid foam boards being two of the best options. Closed-cell spray foam insulation is a strong choice because it effectively repels moisture, resists biological growth, seals the air, and provides excellent thermal protection, especially in hard-to-reach areas. Rigid foam insulation boards are another excellent material as they insulate well, resist water damage, and will not settle over time like fiberglass or cellulose.

Yes, you can technically make a crawl space liveable, but the only way to do so is by converting it into a basement. While some crawl spaces are big enough to walk through and store large items, they lack appropriate insulation and space to be liveable.

As the first layer of water protection for your roof deck and the building materials below, underlayment is designed to prevent water damage, so it’s okay if it gets wet. However, you shouldn’t rely solely on underlayment for protection. If rain interrupts your roof project and you have all of the underlayment down, you’ll likely be fine, but you should install shingles over that layer as soon as possible, as long-term exposure can lead to water damage.

The best basement waterproofing method depends on the specific issue causing the water intrusion. For minor problems, simple solutions like installing a properly functioning gutter system to direct runoff away and grading the soil to slope away from your foundation can be effective.

If you have more significant water problems, the solution will need to be more robust:

  • For standing water on the basement floor, a floor drain or a sump pump system may be the best solution.

  • For water pooling around the foundation, installing an exterior French drain can intercept water before it reaches the basement walls.

Other effective waterproofing methods, which can be used depending on your home's specific needs, climate, and soil type, include sealing the interior walls, landscape alteration, installing interior drainage systems, and using a dehumidification system to control moisture levels.

Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and—if your floors are wood—rotting.
