"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

To ensure your basement walls are waterproof, it's crucial to address any existing moisture issues before finishing. Inspect for signs of water seepage, such as dampness or discoloration, and repair any leaks or cracks. Install a vapor barrier to prevent moisture from penetrating the walls, and consider waterproofing paints or coatings.

Proper drainage systems, such as interior or exterior waterproofing, can also be beneficial.

The foundation repair that will work best varies based on the extent of the damage, the underlying cause, soil conditions, weather conditions, and more. Permanent foundation solutions like underpinning and exterior drainage solutions are better than temporary fixes that don’t address the source of the issue. Some examples of more temporary solutions include mudjacking or slabjacking, waterproof paint, and dampproofing. The best course of action is to have a reliable foundation specialist inspect your issue, treat the underlying problem, and restabilize your foundation.

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.

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.

In some circumstances, foundation refacing or repair may be a better option for your home than sealing a foundation. It’s always a good idea to take steps to prevent moisture problems in your foundation, but if there are any structural concerns, those will usually need to be fixed first. When dealing with foundation issues, it’s a good idea to get a professional opinion so you can avoid bigger problems down the road.
