Basement flooding and sewer backup in Quad Cities (Davenport)
Plumbers for backwater valves, sump pumps and drains.
11 pros in Quad Cities (Davenport)
The Quad Cities sit on the Mississippi, and in spring 2019 the river gauge at Rock Island Lock and Dam broke the all-time record flood crest set in 1993. During that flood, Davenport's water pollution control plant diverted sanitary sewer water into the river. That history shapes how you think about a wet basement here: river flooding, a stressed sewer system and a failed sump pump are different problems, and each calls for a different fix. Before you hire, ask the contractor which problem the work addresses, whether a backwater valve, a sump pump, a drain or waterproofing is proposed, and why. Ask whether a permit is needed in your town and who pulls it, and check that any plumbing work is done by someone licensed for it. Also check your insurance. The Iowa Insurance Division says water and sewer backup coverage is different from flood insurance, and that neither is automatically part of a regular homeowners policy.

Before you hire
Ask which permits the job needs and who will get them; your municipal building department can tell you before work starts.
Get written quotes from at least three contractors for the same work, and check references from recent clients.
Put it in a written contract: the work, price, deposit, start and finish dates, warranty, permits and clean-up. Paying cash to skip it leaves you no recourse.
Questions about hiring in Quad Cities (Davenport)
Does my homeowners policy cover a basement that floods?
Not automatically. The Iowa Insurance Division says water and sewer backup coverage is different from flood insurance, and neither is automatically part of a regular homeowners policy. Each needs a special endorsement. Read your policy or ask your agent before the work, so you know what is covered. Iowa Insurance Division (source, opens in a new tab)
If I buy flood insurance now, am I covered right away?
Probably not. The Iowa Insurance Division says flood insurance through the NFIP typically has a 30-day waiting period before it takes effect. It also says flood damage is often a standard exclusion in homeowner, renter and property insurance policies. Plan ahead rather than waiting for a forecast. Iowa Insurance Division (source, opens in a new tab)
What should a quote for basement flooding prevention include?
Ask for a written quote that names the work: which backwater valve, sump pump, drain or waterproofing system, where it goes, and how water will be discharged. It should state who handles permits, what is guaranteed and for how long, and what happens if the crew finds hidden damage.
Why does sewer backup matter for Davenport basements?
During the May 2019 Mississippi River flood, Davenport's water pollution control plant diverted sanitary sewer water into the river. High river levels strain the sewer system, so ask any contractor whether a backwater valve suits your home and whether a permit is needed before it is installed.
