"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."

"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."

The job was completed in a timely fashion despite rain delays and the post job cleanup was thorough. We highly recommend Avalon Masonry!"

Basement Waterproofing questions, answered by experts

Roughing in and connecting utilities are the hardest parts of finishing a basement, and they’re the parts we typically don’t recommend doing as a DIY project. Unfortunately, your finishing timeline can be extended by weeks while you wait for contractors and inspectors to install electrical wiring, plumbing lines, and heating/cooling equipment and carry out inspections.

Water damage to concrete is often gradual and can take months, if not years, for a concrete structure to be fully destroyed. The process often starts with cracks on the surface, followed by sinking slabs and eventually crumbling cement. Therefore, it is important to repair minor damages early to prevent the situation from worsening.

You’ll need to reseal the foundation every five to 10 years, depending on the sealant you’ve used, the moisture conditions present in and around your home, and the condition of your foundation. Having a foundation inspection conducted before reapplication can help you catch any problems before you begin resealing. Of course, if you notice any new leaks or other moisture problems at any time, it may be necessary to reseal the foundation sooner.

Waterproofing or encapsulating protects against moisture, preventing mold growth and structural damage. These services also enhance energy efficiency and improve air quality by keeping humidity levels in check.

A vapor barrier keeps moisture out of the crawl space, while insulation reduces the amount of unconditioned air—and sometimes moisture—that enters the space. Coupling a vapor barrier with insulation can help prevent humidity and related moisture damage in a crawl space while also making your home more energy-efficient. Just be sure to use insulation that won’t get damaged from moisture, like rigid foam board or expanding spray foam insulation.
