"Concrete Unlimited installed a septic tank and septic bed, trenched and installed a long water line, removed and hauled stumps, made log decks, cleared slash, graded and prepped our cabin site, artfully placed rocks and boulders that were uncovered in the process. Our remote lot had many constraints and he navigated through them beautifully -- and on time. My husband has seen heavy landmoving equipment operated by many people during his career and interacted with many companies on projects. Following the Carr and Dixie fires, where we lost our home and our family cabin, we again saw how various contractors approached and completed projects throughout our neighborhoods. Jesse Gorbet, Concrete Unlimited, and his crew are among the very best we've seen. Deft, nuanced, insightful, graceful, and considerate are not adjectives that normally come to mind with these types of projects but they do here. He was refreshingly excellent in communication, keeping us up to date, suggesting ways to save money and also setting up the project to make it easier for building in the future. Jesse was an absolute pleasure to work with, an unexpected gift. To have one contractor work with us to handle all these tasks themselves, and so professionally, was stress free. We highly recommend him."

Basement Waterproofing FAQs, answered by experts

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. The chances of mold developing depend on several factors, including the severity of the damage and how quickly the area is cleaned and dried. To prevent mold, you must act quickly—ideally within the first 24 hours. Clean up all water and thoroughly dry the affected area. If the damage is extensive, you were unable to address it immediately, or you suspect mold has already started to grow, it is best to assume it is present and hire a professional mold inspector or removal expert to assess the situation.

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. 

The best basement waterproofing method depends on the specific issue causing the water intrusion. For minor problems, simple solutions like installing a properly functioning gutter system to direct runoff away and grading the soil to slope away from your foundation can be effective.

If you have more significant water problems, the solution will need to be more robust:

  • For standing water on the basement floor, a floor drain or a sump pump system may be the best solution.

  • For water pooling around the foundation, installing an exterior French drain can intercept water before it reaches the basement walls.

Other effective waterproofing methods, which can be used depending on your home's specific needs, climate, and soil type, include sealing the interior walls, landscape alteration, installing interior drainage systems, and using a dehumidification system to control moisture levels.

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.

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.
