Water in a Addison basement? Below is what public data says about Addison'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 Addison homeowners need to know which before paying for a fix.

What Addison offers homeowners

Addison says the homeowner is responsible for the sewer lateral from the house to the sidewalk, and the Village handles qualifying blockages on the public side. The Village recommends backflow prevention devices or overhead sewers for homes that get backups.

Housing in Addison

About 35,702 people lived in Addison in the 2020 Census. The median home there was built around 1972, and the biggest share of its housing went up before 1970 (45% before 1970, 35% from 1970–1989, 18% from 1990–2009, 2% since 2010). Roughly 57% of homes are detached single-family houses and 7% are townhouses or other attached single-family homes; about 67% of households own their home.

Older Addison homes (45% pre-1970) are more likely to have block or poured walls with old clay drain tile and floor drains tied into the sewer. Several DuPage programs require disconnecting drain tile from the sanitary sewer and sending it to a sump pump — a common part of waterproofing jobs here.

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.
