"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."

"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."

"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. His contract clearly outlined the scope of work and pricing. 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. He gave a start and finish date, offered fair and reasonable pricing for the service and even completed the project ahead of schedule with photos.

"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."

Basement Waterproofing questions, answered by experts

The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in. 

If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.

Below-ground shelters are the best in terms of durability, but there is a risk of flooding and obstruction. Modern technology and rigorous construction requirements make above-ground shelters a better option for accessibility, safety, and, usually, your budget. They may not have the same aesthetic appeal, but many of their features make above-ground shelters a better option. 

Physically, the most challenging part of finishing a basement is installing egress windows or doors when the space is below ground level. Mentally, the hardest part may be envisioning the project and planning around load-bearing and mechanical obstacles.

A vapor barrier can last over 20 years, but they are vulnerable to pests, flooding, and other natural disasters. If your home weathers a storm or is treated for any pest infestation, make sure to have a drywall pro come check the integrity of your vapor barrier. It’s also important to have a pro install a vapor barrier since improper installation can lead to tears or leaks in the barrier that shorten its lifespan.

Foundation repair uses methods such as underpinning, slab jacking, or application of hydraulic piers. Each technique is chosen based on structural needs, soil conditions, and damage extent, ensuring a stable and secure foundation.
