Effective Solutions for Humidity Issues

When it comes to maintaining a healthy crawl space, humidity is a major concern for homeowners. The problem often lies in how moisture seeps through the open cavities of concrete block walls, leading to a damp, musty environment that can cause structural damage and health issues over time.

At APS Foundation & Waterproofing, we specialize in solving this problem with our Block Wall System. This innovative solution includes:

By integrating the wall sealing system into your crawl space, you not only prevent moisture from entering but also improve the overall air quality and structural stability of your home.

The technical crew showed up on time and worked quickly to finish filling our cracks in the entire driveway. They gave us a choice of colors. They cleaned up and our driveway looks great.

We had APS lift a realign the slab around our pool. Every staff member was courteous and professional. APS maintained excellent lines of communication and they did what they said they would do when they scheduled to do it. The techs were great and left the work clean. A++

I had three teams at my home, one installing gutters, another repairing the garage door lift and a third team worked on filling the voids underneath my driveway along with leveling and filling the cracks in the drive. I am impressed with the foam that was used for leveling the drive. Each person was respectful and professional. The quality of work was topnotch and I would gladly recommend APS Foundation for your projects.

I got a few estimates before deciding on APS. Jason (Design Specialist) is very knowledgeable. He has a lot of foundation experience, and a lot of people experience and it shows. There was no pressure about starting the project. That was a unique feature in comparison to the other companies I received quotes from, and the reason I went with APS. Ramiro (Job Foreman), and his crew Jose and Arturo came here and knocked it out in 3 days in the middle of August. Crawl Space clean out, encapsulation, perimeter drains, floor supports, the works. They don't mess around. They cleaned up after themselves too. Despite the misery of the August heat, they were very polite and professional. Everyone involved was. I highly recommend APS for crawl space repair.

Owner's reply
Windy, thank you for the detailed writeup. Jason takes the no pressure approach seriously, and Ramiro, Jose, and Arturo knocked out a full crawl space job in August heat without cutting corners on the cleanup. We will make sure all four of them see this. 🙌

William Robertson was our first interface with APS and Wow what a great first impression of the company. William provided a very detailed overview of the condition of our crawl space. By the way, it was not a gloom and doom overview. William provided a detailed summary of his recommendations of what we needed. Even when we would ask about more expensive options, he would give us an overview of how that would benefit our need or state that it was not necessary for the condition of our crawl space at the time. William continued to stay in contact with us throughout the installation of encapsulation and followed up upon completion. The installation crew and William were very professional throughout the process. Job well done and would recommend APS to my friends. As a side note, the installation was much cheaper than competitors.

Owner's reply
Thank you Jimmy, this is a great writeup. William is big on giving people the honest picture rather than the scary one, and it's good to hear that came through from the first visit all the way past completion. 🙏
