"we had concrete pads added after home construction. One pad had a 2 inch settlement on one corner. Complicating this was a stone wall sitting atop the pad. Excellent restoration was done by Groundworks From Bozeman. After a thorough evaluation by Ben, Chelsea and Tyler were prompt, educational and successful. I Highly recommend this company for your concrete/foundation needs."

"They came to my residence and provided a cost and time estimate in a friendly neighborly manner. They stayed in touch to confirm our scheduled work date and time. They were punctual and thorough in explaining how the work would be done and listened when I commented on the locations of sprinklers and best approaches as to keep our lawn from unsightly track marks. The work was completed professionally as per our agreement. I would highly recommend them, and will use them for future landscaping work."

Basement Waterproofing questions, answered by experts

Yes, cleaning a crawl space is worth the cost. Although it's an out-of-sight area, neglecting it can lead to significant problems like pest infestations (including termites and carpenter ants), mold, and fungal growth, which can cause structural damage. Regular cleaning helps prevent these issues. While hiring a contractor has ongoing costs, the price for cleaning—typically between $0.50 and $4 per square foot—is much lower than the cost to remediate a pest or mold problem. Additionally, a clean crawl space can lead to improved indoor air quality and more comfortable temperatures in your home.

There are a few downsides to a wet room, the most important of which is the risk of mold growth from the moisture and humidity. Standard bathrooms can have the same issue, but wet rooms are more likely to experience problems because water is less carefully contained. You also have less privacy since the entire bathroom is open, and the room must include waterproofing, which makes wet rooms more expensive to install than regular bathrooms.

Although the two terms are closely related and often used interchangeably, pier and beam foundations and crawl spaces are different things. A pier and beam foundation is made up of concrete piers and wooden beams and creates a space under the home known as a crawl space. There are several types of foundations that create crawl spaces, often collectively known as “crawl space foundations,” but the crawl space itself is separate from the foundation. 

The purpose of crawl space encapsulation is to prevent mold by blocking moisture and reducing humidity. If the vapor barrier is properly installed, it significantly reduces the chance of mold developing within the crawl space. However, mold can sometimes grow behind the encapsulation material, but it will be sealed away from the main area. Additionally, moisture can still condense inside the encapsulated space, so if you notice excess humidity, installing a dehumidifier is recommended to prevent mold and mildew growth.

Yes, basement insulation needs a vapor barrier due to its susceptibility to moisture seeping in from the outside of the house. You should install a moisture barrier before you install insulation or purchase insulation that comes prebuilt with a moisture barrier to avoid water damage in your insulation and costly mold and water remediation expenses.
