"Although I did not hire them, I was impressed by their honesty. He explained what the problem was, and told me that it could best be solved by a carpenter, as it was not a cement foundation problem as I thought it was. He also gave a price range of what he thought it would cost. Would hire if I had a problem."

Even today they are just a phone call away with any questions or anything I have about the work they perfomed in 2021.

Basement Waterproofing FAQs, answered by experts

The foundation repair that will work best varies based on the extent of the damage, the underlying cause, soil conditions, weather conditions, and more. Permanent foundation solutions like underpinning and exterior drainage solutions are better than temporary fixes that don’t address the source of the issue. Some examples of more temporary solutions include mudjacking or slabjacking, waterproof paint, and dampproofing. The best course of action is to have a reliable foundation specialist inspect your issue, treat the underlying problem, and restabilize your foundation.

If you don’t wish to dig it out and convert it into a finished basement, you can still encapsulate your crawl space to protect it from damage for an average cost of $5,500. Finishing a crawl space beyond this isn’t really worthwhile, as the low ceilings mean you won’t be able to use the area as living space.

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor.

Since basements are prone to water and moisture issues and the resulting problems can be expensive to repair and potentially damaging to your home, basement waterproofing is almost always worthwhile. Even for homes that haven’t experienced water infiltration, waterproofing the basement is insurance against facing expensive repair bills in the future. All basements will leak at some point, so fixing drainage issues and taking steps to prevent moisture and water infiltration is wise.

The primary reason homes have crawl spaces is so the foundation can reach down below the frost line to avoid dangerous soil movement and structural damage when the ground freezes. They’re more popular in colder climates where the ground freezes down to a few feet, and slabs are most popular in warmer areas where there is no frost line. Crawl spaces also provide a space for utility lines to run where they’re at less of a risk of freezing.
