"Excellent job, the total cost charged actually saved me lots compared to the other quotes I was given by other companies. I shopped around a lot for good prices. My basement walls had cracks that went straight onto the floors and water was seeping through. Everything was fixed in one day. They came back after a week to do a follow up to make sure everything was good and dry, which it was. Overall very happy and would recommend them."

"I had a crawl space encapsulation done three years ago. The work was professionally done by competent friendly patient professionals willing to answer any and all questions about their work. Most recently I had tech Bradley Innocent conduct the annual inspection of the work, replace the filter in the dehumidifier and survey the property for any potential problems. This young man was professional, efficient, and explained what he was there to do and why. Companies need more competent professionals like him."

"From water in my house, due to Hurricane Milton, and the discovery of cracks on the exterior of my concrete block house â ¦ to a week of digging, grinding, cementing, and waterproofing the slab, the interior walls of two rooms, and fixing cracks in the exterior walls of my house, this was quite an experience! As annoying and disruptive as something like this can and will be, all in all it wasnâ t nearly as bad as I anticipated, mainly due to Brian, the lead. He was informative, asked my opinion, explained why things were done as they were, and went over and above to keep me in the loop. Both he and Corey were respectful and pleasant at all times. As you can imagine, as a woman living alone, it is difficult to have male workers in and out of the house. At no time was I concerned. Yes, this experience was a bit disruptive and I knew it would be â ¦ but it was ever so less painful and disruptive than I thought it would be and I thank Brian for that. And, I no longer have to worry about water in my house from hurricanes. May I also say that the response from this company was exceptional. I entered my information into their website the day after the hurricane hit. Within 15 to 20 minutes, I received a phone call from the CEO. We talked a bit and he made an appointment for the next week. He kept me informed by text as to his arrival time and arrived when he said he would. He told me what the company would do and sent a contract to me which I signed. I was given a start date and it never changed. The work that was done by the team that arrived was what he said would happen. How incredibly refreshing that a company actually did what they say they would do in the timeframe that was set. Thank you again. I hope I am never in the position to need this companyâ s services again. ð But, for anyone else out there who is, I donâ t believe you could do much better than Advanced Environmental Services. Five stars are not enough."

Basement Waterproofing questions, answered by experts

Encapsulation can take the place of crawl space vents since it protects the area from moisture and air all year round. Determining whether you should open or close crawl space vents can be complicated since it often depends on the weather and humidity. Skip this step by investing in crawl space encapsulation whenever possible.

A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can’t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it’s legal to do so.

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.

No, your basement dehumidifier doesn’t need to be on 24/7. While it’s an excellent tool for tackling damp, musty air, especially in humid seasons, leaving it running nonstop can backfire. Over-drying the space can mess with your sinuses, warp wood, and even crack certain materials. Instead, only use your humidifier when moisture levels rise above 50%, and then give it a break when the humidity levels drop.

Unfortunately, mold can grow pretty much anywhere, on any kind of surface. However, you’re most likely to see it in damp areas like basements or bathrooms, as well as anywhere there has been a water leak. Consult a local mold specialist to determine if certain areas of your home are prone to mold based on climate and other factors.
