"Felt rushed to approve the work and pay the balance. Discovered multiple issues later. Just inside the door there's a rock they missed, so now it's under the plastic, which will sooner or later puncture through. I asked for a better door than the one the first installed, but the second was also poorly made and didn't come close to sealing. Called/talked to someone about the issues, but afterward they stopped returning my calls. They also left lots of debris on the ground. The inspection didn't pass for multiple reasons. Waiting for them to come back and address the issues the inspector found. Update: THBS did follow up and fix the issues. They constructed a new crawlspace door that seals, which was the biggest issue. They took out the problematic rock. The inspection passed."

What’s more, you can enjoy the peace of mind that comes with our lifetime warranty and our industry-unique money-back guarantee!

"Donâ t believe everything they tell you about their system. We hired this company because during heavy rains (4inches or more), our basement tended to flood. We discussed this with the sales rep who came out, Albert Morrow, and told him we didnâ t have problems unless it was heavy rain. He recommended his company and told us the system was designed for this. After we had the system installed, we had no problems but also no heavy rains for 2-3 months. However, in December we had 5 inches of rain during one storm, and OUR BASEMENT FLOODED once again. A technician came out and basically told us the system worked the way it was supposed to but during flooding conditions the system was overwhelmed . So basically we paid $7500 for them to come out and install a system that does not work when it should. We would have been better off just to keep our money in our pocket and just wet-vac the water out when we have heavy rain. NO,WE DO NOT RECOMMEND THIS COMPANY OR THEIR SYSTEM. We are basically screwed out of $7500."

"I want to share my experience with Chris, owner of Crawl Space Jam, who recently completed an encapsulation project for me. I received quotes from several companies, but Chris truly stood out.

He was very thorough in explaining the problem with water standing beneath my house, how it could be resolved and what the finished results would look like. He not only provided pictures of the space before work began, but kept me informed daily of progress updates and photos. He welcomed questions and answered immediately with clear explanations.

"They have deceptive business practices where they inflate their billing to your insurance company for services they did not perform and threatened try to place lines on your property instead of adjusting the billing for the work they did perform. If this company comes to your home beware. The will subject you to scrutiny from your insurance company due to their overbilling. They stacked my wood floors against my wall and the damage is still there. They left debris in my yard. They will not admit nor correct their errors."

Basement Waterproofing questions, answered by experts

Crawl spaces are prone to issues caused by excess humidity and improper ventilation, but that doesn’t mean you should avoid buying a house with a crawl space. A home that is encapsulated and well-maintained shouldn’t have any more issues than a slab or basement home.

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.

Sandbags are the most common and efficient way to create a flood barrier at home. Some local authorities pass them around to homes before the risk of a flood. Otherwise, you can use flood-proof house materials, like burlap or woven plastic bags, to make sandbags and fill them with sand or cat litter. Make sure that when you stack them, they’re tightly laid on top of each other, creating the effect of a firm wall against accumulating water.

Yes, barndominiums can have basements. Barndominiums are typically built over concrete slabs, so barndo basements are not very common. However, it is possible to include a basement in a barndominium blueprint as long as you’re building completely from scratch. Barndos can have the same types of basements as traditional homes, including full or walk-out basements.

In most cases, a crawl space will not dry out on its own unless the moisture comes from an uncommon flood and isn’t expected to be a recurring issue. For most homeowners, moisture problems in the crawl space will only continue to get worse over time, so addressing the underlying problem with gutter systems or a foundation drainage system and setting up a preventative solution like a dehumidifier is necessary.
