Questions and Answers
Where a public office has the final say, the answer names it, so confirm anything important there first.
What is this site, and who pays for it?
Basement Waterproofing Omaha NE is a referral and advertising service, not a waterproofing company or a plumber. Once you send the form, one independent local contractor receives your request to be contacted and handles everything from there. You owe nothing and are given nothing. A contractor may pay a flat fee to advertise, though a free trial means none is charged yet.
Why do basements around Omaha take on water?
The ground and the age of the houses both play a part. USGS mapping shows wind-blown loess across the uplands with clayey glacial till mostly buried below it, and that pairing can hold water against a wall or drain unevenly. Census survey data dates close to half of Omaha's homes to before 1970, and older poured, block, brick or stone walls can let moisture through joints and cracks.
Water came up through my floor drain. Who should I tell?
Water rising from a floor drain is usually a sewer backup, a different problem from seepage and one waterproofing can't fix. For an Omaha address, the City takes street flooding and sewer backup reports at 402-444-5332, and Public Works answers sewer questions at 402-444-5220. The towns have their own offices: Bellevue, NE at 402-293-3135, Papillion, NE at 402-597-2043, Ralston, NE at 402-331-6677, Blair, NE at (402) 426-6698 and Plattsmouth, NE at 402-296-2522 ext. 1101.
Will the CSO Program keep sewage out of my basement?
Not by itself. Parts of older, eastern Omaha still have pipes that carry rainwater and wastewater together. The City's CSO Program, which started in 2009 and runs to 2037, is working through nearly 60 projects, aiming to capture or treat 85% of combined sewage in an average year. Its target is overflows into the Missouri River and Papillion Creek, and homeowners still reported basement backups after the Sept. 30–Oct. 1, 2026 storm.
Where should a sump pump send its water?
Outdoors, well away from the foundation and from the neighbors' yards, and never into a floor drain, laundry tub or sewer line. A licensed plumber or your city office can tell you where the outlet should land. Hooking a pump into any drain, or adding a backwater valve, calls for an Omaha-licensed plumber or sewer layer and a permit; in a town, ask which plumbing license the city accepts.
How much does waterproofing a basement cost?
For 2026, Fixr's national figures put most jobs between $3,000 and $10,000, averaging about $5,000. Its line items, smallest first: epoxy injection at $250 to $1,000 a crack, a sump pump put in for $600 to $2,500, and interior perimeter drain at $40 to $120 a linear foot. Nebraska has no price source of its own, so the contractor's written estimate is what counts.
Does Nebraska license waterproofing contractors?
Nebraska has no statewide general contractor license. Instead, contractors must register with the Department of Labor before doing construction work; look one up at dol.nebraska.gov or (402) 471-2239. Inside Omaha, the City separately licenses building and plumbing contractors and sewer layers, which you can check at omahapermits.com or with Permits & Inspections at (402) 444-5350. Each town sets its own rules, so ask its building office.
What should the paperwork look like, and can I cancel?
Nebraska's Attorney General suggests a written contract covering what will be done, which materials, the full price, when it will be finished and how to reach the contractor. Put down a reasonable amount up front, pay the rest once the work is complete and don't pay in cash. Collect a lien waiver with each payment. Sign in your home and you may have three business days to back out. For complaints, the Attorney General's consumer line is (800) 727-6432.
Will my homeowners policy cover a sewer backup?
Maybe not. A basic policy often leaves backups out unless you bought a sewer-backup rider or endorsement, and flood damage sits outside standard homeowners coverage. Only your policy's wording settles it, so go over it with your insurer or agent; the Nebraska Department of Insurance fields general questions at (402) 471-2201. This site plays no part in any insurance matter.
