"From the minute they got out of the truck to check our project, to give us a bid we knew they were the company we would hire. They seemed to know what we wanted by way of design and finish, before we spoke. Where other companies had said flat out “We won’t do this.” “Too much work removing old concrete.” Poor access.” Moli said, “Yes, this old concrete gotta go. But, it’s no problem. We bust it up. We take it out.” At the end of the first day all of the old concrete had been removed and taken away. At the end of day two all the forms were set. Day three was rebar and detail work making all ready for the pour. Day four The concrete was poured stamped and finished. On day five everything was picked up cleaned up and they were gone. These are good people. They do good work and they are as honest as the day is long."

Basement Waterproofing FAQs, answered by experts

While it’s possible to seal a foundation yourself, it’s not recommended, as it’s a tricky and labor-intensive job. Foundation sealing is best left to the pros to save yourself time, remove the risk of doing it wrong, and keeping yourself safe. Call a foundation repair professional near you to see what the job will cost.

Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.

If not properly maintained, an underground downspout may damage your home's foundation. A clogged downspout can back up, causing water to pool around the base of your home and seep into the foundation. Regular inspections and maintenance keep your downspout in good working order, preventing damage and protecting your home.

Standard homeowners insurance policies may cover basement water damage or flooding, but only if it is caused by a sudden and accidental event that is a covered peril, such as a burst pipe or a failing appliance. Damage caused by natural flooding from extreme weather, groundwater seepage, or heavy rain is typically excluded and requires a separate flood insurance policy. Some insurers also offer an optional water backup endorsement for issues like sewer backups. Review your policy or speak with your agent to understand your specific coverage.

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.
