Water in a Lisle basement? Below is what public data says about Lisle's homes, the local rules that matter, and how to get matched with one licensed local pro for free.

Wet basement or sewer backup? Know which one you have

Groundwater seeping through walls or the floor is a waterproofing problem (drain tile, sump pump, crack repair). Water coming up through a floor drain during heavy rain is often a sewer backup, which calls for backflow protection or an overhead sewer. Many Lisle homeowners need to know which before paying for a fix.

What Lisle offers homeowners

Lisle offers an Overhead Sewer Cost-Share Program: after a sewer backup, the Village splits the cost 50/50, up to $2,500, for an overhead sewer or another backup-prevention device.

Housing in Lisle

About 24,223 people lived in Lisle in the 2020 Census. The median home there was built around 1983, and the biggest share of its housing went up between 1970 and 1989 (15% before 1970, 55% from 1970–1989, 20% from 1990–2009, 10% since 2010). Roughly 43% of homes are detached single-family houses and 11% are townhouses or other attached single-family homes; about 56% of households own their home.

Many Lisle homes date from 1970–1989. Those basements often have a sump pit already; check pump age, discharge location and whether you have a battery backup before a storm season.

Ask any waterproofing contractor for a written diagnosis of where the water is coming from, what they'll fix, and whether a village permit is needed.
