"Rod & the guys at SealProMax have been incredibly accommodating and helpful throughout the stressful situation which was my leaky basement. Rod came in and was able to describe how their product works, gave a live test sample, then explained that they will use as much solution as necessary to stop all water from entering my basement. After 3 days worth of locating and filling cracks & air pockets with their material, it appears that my basement no longer will see flooding every time it rains. They have been adamant about the quality of their product and have given me the piece of mind knowing that they will return as many times as needed in order to ensure that our problem will not return. Add all of this on top of their warranty and I can happily say that their service has been well worth the money spent. I would recommend Rod & his crew to anyone in need of waterproofing any leaks in their basement who are willing to spend their money on a product & service that cannot be matched."

"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

French drains and yard grading systems are two highly effective ways to fix standing water around the foundation. Since the French drain uses a perforated pipe covered by gravel, you won’t have to worry about water taking the soil away from your foundation. Meanwhile, yard grading levels out the ground to prevent water from gathering around your foundation.

Many prevention methods can be used individually or in combination to waterproof your basement. Some of the most common waterproofing methods include:

  • Using dehumidifiers 

  • Silicate concrete sealers

  • Vapor barriers 

  • Baseboard channels 

  • Drain tile systems

  • Waterproofing paint

  • Drainage systems

  • Epoxy injection

  • Interior French drains

  • Exterior excavation and waterproofing

  • Cement waterproofing

  • Weep tiles

  • Liquid membrane

  • Sheet membrane 

  • Yard grading

  • Gutters and downspouts

Ductwork sweats due to a temperature difference between the air inside the ducts and the surrounding air, similar to how a cold drink develops condensation in the heat. This sweating is a sign that your HVAC system is not operating at peak efficiency. The best way to keep ductwork from sweating is to wrap it in proper insulation, which also improves your system's energy efficiency. Another option is to close off your crawl space and install a dehumidifier to dry the air and lower its dew point.

While a standard gutter system is widely considered the most effective way to prevent water damage to your home's foundation, several alternatives are available. These options can be used on their own in certain climates or as supplementary protection.

Common alternatives include:

  • Rain Chains: These are decorative chains that hang from the roof's edge, guiding rainwater to the ground.

  • Drip Edges: These metal strips are installed at the edge of the roof to direct water away from the fascia. While often used with gutters, they can be paired with a ground-level solution but are typically not sufficient on their own.

  • Rain Dispersal Systems: These systems work by breaking up the heavy sheet of water flowing off the roof, dispersing it over a wider area.

  • French Drains: This ground-level system uses a perforated pipe in a gravel-filled trench to collect and redirect water runoff away from the house.

  • Drip Paths: Placed directly below the roofline, these paths made of concrete, stone, or other materials prevent soil erosion and guide water away.

It's important to note that some alternatives like rain chains and dispersal systems may not be adequate in regions with heavy rainfall because they don't divert water away from the foundation as effectively as a full gutter system. Ground-based solutions like French drains can be very effective but are often more expensive and can affect your landscaping and curb appeal. Many experts recommend installing a full gutter system for maximum protection and using alternatives as supplementary measures.

The best way to ensure the ground next to your home’s foundation drains properly is to divert water away from it as much as possible. While a flood wall can stop water from entering the house, gutters and spouts can help direct rainwater and melting snow away from the foundation. Keep your gutters as clear as possible from dead leaves and other yard debris so they can effectively divert water from your house. Add extenders to the spouts so the water runs out and away from your home, not into the surrounding soil.
