Answers Homeowners Look For
No two houses drain alike, so confirm anything important with the office each answer names.
Does this site do basement work, and what does asking cost?
It does no work, and asking costs nothing. It is a referral and advertising service, not a contractor or a plumber, and it never prices or agrees to a job. Your request to be contacted reaches one independent local contractor. Contractors may pay a flat fee to advertise here, waived during a free trial; no homeowner is ever charged or rewarded.
Why do basements around Indianapolis take on water?
Soil and age both matter. The Encyclopedia of Indianapolis describes glacial till ranging from clay to boulders across the uplands, with sand and gravel terraces beside the larger streams. Dense till can hold water against a wall, and those gravels can carry groundwater. Census survey data dates about 16% of the city's homes to 1939 or earlier, and aging brick, block or poured walls can admit moisture at joints and cracks.
Water came up through a floor drain. What does that mean?
That pattern points to a sewer backup more than to groundwater seepage. At an Indianapolis address, report it to Citizens Energy Group at (317) 924-3311. If Citizens finds its public sewer clear, the trouble sits on the private side, which is a job for a licensed plumber. Outside Citizens' area, start with your town's sewer utility.
DigIndy is finished, so why can backups still happen?
Citizens built the DigIndy tunnels, 28 miles of them, to keep at least 95% of sewer overflows out of the rivers, and construction wrapped up in 2025. That cuts overflows; it was never described as a cure for basement backups. In April 2026 a short, heavy rain still forced water up through basement drains on one Broad Ripple block.
Where should a sump pump send its water?
Outdoors or to a storm sewer, never the sanitary line. Citizens Energy points out that state utility regulators prohibit clear-water discharges to the sewer, and through Correct Connect it mails a letter requiring a fix when it finds one. Any connection between a sump and a drain or sewer pipe counts as plumbing, so it belongs with a licensed plumbing contractor and the right permit.
What does basement waterproofing usually cost?
Fixr's 2026 national table says a typical project costs $3,000 to $10,000, with an average of roughly $5,000. It also lists $40 to $120 per linear foot for an interior perimeter drain, $600 to $2,500 to install a sump pump and $250 to $1,000 per crack for epoxy injection. With no Indiana-only figures, the contractor's written estimate is what counts.
Does Indiana license waterproofing contractors?
Not statewide. The Indiana Attorney General says licensing requirements vary from one community to another. Ask any contractor which local license or registration it holds for your address, then check it with the permit office, which for an Indianapolis address means the City's Department of Business and Neighborhood Services, (317) 327-8700. Plumbing is separate and needs a license from the Indiana Plumbing Commission.
What belongs in the contract?
For any job over $150, Indiana's Home Improvement Contracts Act calls for a written contract that the contractor signs before you do. Check for a reasonably detailed description of the work, the price, rough start and finish dates, and whether an unnamed subcontractor will supply labor or materials. No down payment can be required until the contractor has signed, and the Attorney General advises paying no more than a third up front.
Can I back out after signing?
Possibly. For certain deals you didn't seek out that were made face to face away from the seller's place of business, you may have until midnight of the third business day to cancel. Whether that fits a request you started online is unsettled, so read the contract's cancellation terms. The Attorney General's Consumer Protection Division answers questions at 1-800-382-5516 or 317-232-6330.
Will homeowners insurance pay for a backup?
Often not unless you added coverage. Citizens Energy says most policies leave sewer backups out without a separate endorsement, typically about $40 to $160 a year. Your policy wording decides it, so check it and ask your agent or insurer. Insurance is outside what this site does.
Still Have Questions?
Some answers only come clear once someone has seen the walls and floor. The estimate request form lets one independent local contractor know you'd like to be contacted.
