"Dan was here this morning, showed him where water was leaking in over our slab and ruining the flooring in the master bedroom. He gave me the full range of possible remedies, from installing a eaves gutter on the roofline outside the bedroom to a full (very expensive) sealing of the entire exterior foundation. And actually recommended that we start with the gutter (which I can do myself) and then monitor the area next rainy season and see if that fixes the problem. No pressure to hire them or spend big $$, just good advice. Couldn't have asked for more. Highly recommended- this is real service!"

"We worked with Ali (sales manager) and Tony (project manager), who took the time to design a project that made sense for our property and our budget, made a number of suggestions and recommendations and were never pushy or tried to "sell" us on something. The crew really went above and beyond to provide top quality workmanship and overall we were in very good hands. Highly recommended!"

"Perfect!!! We originally d to repaint the whole house. Since that was out of our budget, we asked Tony to touch up our walls. When he finished, it looked like we had brand-new walls!!! Although it's the same beige color we already had, they look spectacular!!! He did the whole house in about 6hrs."

"Gil is a pleasure to work with. After my initial contact he came by as scheduled to review the job site and meet with me. Work was scheduled that same week and completed in 3 work days. Gil’s crew was skilled and efficient. Gil did note that I had some drainage issues and recommended the addition of drains to the concrete project. His price for the drain was competitive and would insure that my side yard drainage issues that occurred during heavy rains are remedied. Gil and his crew poured/finished a beautiful new walkway. They also did an excellent clean up when finished. I highly recommend GM Pacific Pro (Gil) and plan to use his excellent skills in the future for more projects."

"Response was immediate, receptionist was very courteous. I had a doctor's appt that I had to squeeze in that day and she was very understanding and worked around my schedule and kept in touch to advise me when Daniel would be there. Daniel was very professional, nice and cooperative. Did the install in a timely manner. Had a little leak but fixed it. That night I ran the disposal and saw that there was a little bit of water under sink. Called the office and they sent him right back immediately. He checked it out and explained there was some leftover water that dripped down when I used it the first time so there was no problem like I thought, but was very patient and rechecked everything assuring me it was fine."

Basement Waterproofing FAQs, answered by experts

The best ventilation for a crawl space is a fully encapsulated crawl space with its own separate ventilation system. If you go this route, ensure you have the proper crawl space code requirements done and dusted before encapsulating your crawl space with a moisture barrier and installing appliances that may not be up to the proper specs.

Yes, water and water vapor can seep through cracks in your basement floor, which means you should address all basement floor cracks, even if they don’t indicate structural issues. Sealing settling cracks and shrinkage cracks is a good idea to keep water and moisture outside where it belongs. Doing so can improve your indoor air quality, reduce the risk of mold growth, make your home more comfortable, and help prevent pest infestation.

Some basement waterproofing methods can actually cause your water or moisture problems to get worse, which is why it’s so important to call in a professional who knows how to solve your underlying issue and use the appropriate waterproofing methods. An example of this would be applying latex waterproofing paint to the insides of your basement walls without fixing the water issue outside. Doing so can trap moisture in the basement walls, which can promote mold growth, peeling paint, and even damaged concrete. However, when done by a professional, the only downside to basement waterproofing is the up-front cost.

Interlocking garage tiles made with PVC are the most effective for garages with past issues of humidity and flooding because damp concrete is not suitable for paint. Epoxy coating is also water-resistant and can prevent mold buildup. Finally, porcelain tiles are a wonderful option for wet conditions if your budget allows.

In most cases, it is safe to live in a home with minor foundation problems, but you should not let the issues persist. Virtually all foundations have small cracks from normal settlement, which are not a structural concern but should be sealed to prevent water intrusion. However, major damage—such as large structural cracks, sinking foundations, or bulging walls—can make a home unsafe. Other issues that can pose safety and health risks include poor indoor air quality from mold or pests, uneven floors, and rotten beams or joists. It is always best to have a foundation repair expert or structural engineer inspect any issues to determine if your home is safe to live in.
