Offers commercial services

We bring something completely different to basement waterproofing and waterproofing in general. We are not the company to call if you have large amounts of water entering your foundation or basement. However, if your foundation is in somewhat decent shape and un-painted. We can stop the moisture from seeping through your walls and floor that cause stored items from being covered in mold and mildew and make your basement far healthier and a truly usable and dry space permanently.\nWith a one-time application using 100% green products that do not change the surface of your concrete surfaces. You can safely store items or furnish your basement and even install hardwood flooring with confidence. Our waterproofing works by using crystalline technology that enters your concrete going where the moisture goes deep into your concrete walls and floors. When moisture is present these crystals expand up to 16 times their size sealing the moisture out of your basement including cracks and joints.

Basement Waterproofing questions, answered by experts

You should take care of any sign of water in your basement, whether it’s dampness after heavy rain or puddles of water on the floor. Besides potentially causing a health hazard, the moisture can damage your home’s structure and foundation. Furthermore, mold can grow quickly and spread throughout the rest of your home. With mold remediation costs ranging between $1,200 and $3,400, it’s best to avoid mold issues by fixing the leak.

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, usually you will need some kind of vapor barrier on the exterior walls when the framing is attached to concrete and masonry surfaces.

You can seal a concrete slab by cleaning the surface, filling in any cracks, etching the surface, applying a sealer, and letting it dry. Concrete slabs don't typically need sealing, but you can use a topical concrete sealer if you notice signs of water damage. If you haven't already fixed the cause of the leak, then you'll want to repair the plumbing before you seal a concrete slab.

The most cost-effective foundation repair is using masonry patches and sealants to seal foundation cracks and offer some support to prevent further damage. These methods are used to fix minor foundation cracks quickly. However, they’re not suitable as a long-term solution, and they only offer minimal stability. On average, masonry patches and sealants cost $500, but a sealant like an epoxy crack injection can total over $2,000. If you’re handy and only looking for a temporary solution until you contact a local foundation repair contractor for a more permanent one, you can save hundreds by DIYing this repair.
