"I had my foundation and basement waterproofed from the inside by Groundworx. The first bit wasn’t good bc I got my appt cancelled and then the next appt no one showed up. So, by appt #3 I got Carlton. He was great. Super helpful, knowledgeable, etc. I purchased the services bc we really needed it asap as I had major mold growing in my basement from the previous owners negligence. I do feel like the price was too high but that’s a Groundworx issue. NOT a Carlton issue. I understand the rep doesn’t control the cost of services. For two days and waterproofing it was around 13-14k. It was extensive work but I did the demolition and removal myself to save $$. The work started and we had Von, Tim, Will and another gentleman. The guys were great. Beyond awesome. They explained so much and helped me with my silly questions. We really enjoyed them and they made the job site so clean it was like they were never there (except for my new pump and my ripped out basement haha 😂) they clearly know"

"58 foundations came to do waterproofing for my crawl space. The crew was prompt, very professional, and did a fantastic job. They accidently cut an electrical line that no one knew was there...and the service manager insisted on paying for repair...which occurred that afternoon. I was so impressed with their demeanor and their professionalism. They left my crawl space clean and neat. I was very glad I had hired them. I highly recommend this company."

"The workers were outrageously good. The guy that did the estimate was under what it should have been and it cost us double the amount, but the guys who did the work were fabulous and made it work. It cost more, but the basement does not have a smell or anything, so I can't blame them for it. They were done in a week. I was embarrassed, there wasn't a speck of dirt when they were done. It was clean as a whistle, and it wasn't like that when they walked in. They were really good. They recommended an electrician, and so even if they didn't do some part, they support you and help you find them. They check up and make sure everything is okay. They call back every time you call them. They did a great job."

Basement Waterproofing FAQs, answered by experts

When considering finishing your basement, take into account a few pros and cons:

Pros

  • Can increase the value of your home

  • Separate space from the rest of the house 

  • Customize and personalize the basement to suit your needs and style

  • Increase the amount of living space in your home

Cons

  • May not regain enough value to cover the cost of finishing

  • Lack of natural light if it’s below ground level

  • Moisture or flooding can cause costly damage

  • Installing plumbing and electrical can be messy and costly

The most challenging part of finishing a basement is addressing moisture control. Basement waterproofing is an essential task that requires a professional’s skills and knowledge. If you don’t properly waterproof your finished basement, it’ll be vulnerable to dampness, water damage, and mold growth. Ensuring proper insulation and ventilation to combat these issues while meeting building codes adds complexity to your remodeling project.

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.

It is better to have a crawl space that is tailored to the outside temperature, your needs, and the season. For example, it is much better to have a vented space when it’s very hot outside and your AC bills are sky-high. Conversely, when the temperature drops and humidity rises, it is almost always better to have your vents shut and covered if possible.

The primary downside to crawl space encapsulation is the high cost, which can be several thousand dollars. Additionally, the process can make future repairs more complicated by limiting access to plumbing and electrical wiring within the crawl space. Encapsulation also requires sealing off any vents, which can be a disadvantage for home designs that benefit from the airflow they provide. It's recommended to consult with a crawl space contractor to determine if the benefits outweigh these potential drawbacks for your specific home.
