"It went well. They are being professional in their follow-up as they are trying to have us install an expensive basement drainage/pumping system. We haven't decided yet, as it will be part of our basement gut/rehab project."

"This business was professional, communicative, and on time from my initial inquiry to when the job was performed. When I initially called, they were able to get someone out to provide a quote within 2 weeks and had me booked within another couple weeks. I was provided a quote online, and that's what I ended up paying. No fine print. Everything was completely transparent. William and another person came to do the actual sump pump installation. They were on time and finished a rather challenging installation (the pipe exit needed to be in a different room than the actual pump) within 4 hours or so. He explained everything to me clearly and was friendly, courteous, and professional. I would absolutely recommend these guys if you're looking for any kind of basement repair/waterproofing."

"We hired Leal Restoration to clean up water damage on three floors of our house. They came early on a Saturday morning, worked all weekend and finished the job on Monday. This included drying out the area, removing debris, and replacing a ceiling. The work was done efficiently and carefully. Leal turned a disaster area into a clean and back to normal living space in 3 days. Amazing!"

"Khaled and his team were outstanding. The attention to detail, the quality of the workmanship and Khaled's attention to my questions and concerns during the project were all top notch. As with any project this size (mine was an entire basement remodel approximately 800sqft that included some minor demo), there were some complications, but the measure of any situation is how the stakeholders address it and there too, Khaled proved that he is made of superior customer service mettle. He got in front of the problems we were facing and addressed them methodically and kept me apprised as needed. He has a marvelous crew and they are all quite fun and knowledgeable. I absolutely love my finished basement. The walls and the painting job alone makes it worthwhile, and that was just the finish work! Fantastic! Strongly recommend Abalia for all your construction and remodeling needs."

"We’re very pleased with the repair of our driveway retaining wall and stone veneer construction. James gave us great direction on how to repair the wall and the workers did a fabulous job. The job was completed in a timely fashion despite rain delays and the post job cleanup was thorough. We highly recommend Avalon Masonry!"

"They did an excellent job repointing the exterior of my foundation and brick piers in the basement. I had a tight schedule and they worked through the weekend without me asking. Showed up early and worked long days to get it done. One of the guys was able to shimmy into a very tight and awkward spot due to the porch structure to get every area of the foundation. I pointed out a couple missed areas and they happily came back the next day to finish the job. I will be using them for future projects."

Basement Waterproofing FAQs, answered by experts

Yes, crawl spaces can attract bugs, especially since moisture tends to build up in the space, and moisture attracts pests. A good way to prevent pest infestation in your crawl space is to install a vapor barrier—called crawl space encapsulation—on the interior to seal the space, along with a French drain or some other kind of foundation drainage system outside to keep runoff out of your crawl space. You can also seal foundation cracks and repair damages to cut off access to pests.

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.

You should take care of any sign of water in your basement, whether it’s dampness after heavy rain or puddles of water on the floor. Besides potentially causing a health hazard, the moisture can damage your home’s structure and foundation. Furthermore, mold can grow quickly and spread throughout the rest of your home. With mold remediation costs ranging between $1,200 and $3,400, it’s best to avoid mold issues by fixing the leak.

Crawl space encapsulation typically lasts between 10 to 20 years. If you experience a catastrophic event, like a flood, or poorly encapsulate your space with low-quality materials, it may only last a decade. Otherwise, as long as you properly maintain your crawl space, a high-quality encapsulation can last more than 20 years.

You don’t always need to install a dehumidifier in your encapsulated crawl space, but it might be a good idea in certain instances. If you notice obvious signs of condensation, mold, or musty smells permeating from your crawl space, a dehumidifier can help. It’s ideal for homes in humid areas.

In a worst case scenario, structural damage like rust on metal beams, rotting wood, and swelling on doors and windows can signal moisture problems that would benefit from a dehumidifier.
