Common Questions
Answers on cost, systems, insurance, and warranty.
Cost depends on the size of your basement and the type of system needed — interior drainage systems are typically less expensive than full exterior excavation, and a foundation crack injection is less involved than either. Every estimate is free and includes a written price specific to your home, so you'll know the actual cost before committing to anything. Our cost guide has the ranges we quote.
Interior systems install a drainage channel along the inside perimeter of your basement floor, tied to a sump pump, and are generally faster and less expensive to install. Exterior systems excavate down to the foundation footing and apply a waterproof membrane and drain tile from the outside, which is more thorough but more involved. We'll recommend the right option based on how water is actually entering your specific basement.
Most standard homeowners insurance policies do not cover basement waterproofing as routine maintenance, since foundation seepage is typically considered a gradual issue rather than a sudden, accidental event. Coverage can vary by policy and by the cause of the water intrusion, so it's worth checking directly with your insurance provider about your specific situation.
Common signs include damp or discolored walls, a musty smell, white mineral staining (efflorescence), peeling paint, visible cracks in the foundation, or standing water after heavy rain. Catching these signs early is usually less expensive to fix than waiting until there's visible mold or structural damage. Our free Wet Basement Diagnosis gives you an instant read.
Most interior drainage system installs are completed in one to two days. Full exterior excavation projects can take two to four days depending on the size and depth of excavation needed. We'll give you a specific timeline as part of your written estimate.
Yes — our basement waterproofing systems come with a written, transferable warranty, meaning it stays valid even if you sell your home. Sump pump installations include a warranty on both equipment and labor. Ask about specific warranty terms during your free estimate.
Yes — crack injection is a standalone, one-visit repair, and it's the least expensive waterproofing work we do. The free inspection tells you whether the crack is the whole problem or a symptom of one. See our Foundation Crack Repair page.
Yes — drainage and sump pumps, sealed vapor barriers, dehumidifiers, and cleanouts for crawl spaces that are damp, musty, or taking on water. See our Crawl Space Encapsulation page.
