Basement waterproofing questions, answered

We look at every basement wall, the floor joint, the sump, window wells, downspouts and the slope of the yard, take moisture readings where water shows, and explain what we found. You get a written price for the fix we recommend.

Usually under an hour for a typical basement.

Only a rough range. The real price depends on how much wall is involved and how the water gets in, which takes a look. See the cost guide.

No. Some basements need a drain, some a crack injection, some just a downspout extension. The estimate says why.

Ohio does not license waterproofing at the state level. The crews are registered and insured; plumbing and electrical parts of a job go to licensed tradespeople.

We do, where one is required. Exterior excavation and foundation work usually need one from the City of Columbus or Franklin County building department.

Yes, in Delaware, Fairfield and Licking county towns close to Columbus. See service areas.

Crack injection: a few hours. A sump: a day or less. An interior drain: two to four days. Exterior work: several days per side, depending on depth and access.

Concrete cutting is loud and dusty. Crews use dust control, cover what they can and haul away debris.

For the inspection, yes. For the work, someone needs to let the crew in and see the finished system.

It depends on the work and is written on the estimate. We don't promise anything that isn't on paper.

Wet springs saturate the clay; dry years don't. Sumps age and footer drains silt up. A basement can be dry for years and then start leaking.

No. Water from a floor drain during a storm can be a sewer backup, which is a plumbing problem. We tell you if that's what we see.

Yes. That's one of the main reasons people waterproof first.
