How to Maintain a Dry Basement in Chicago this Fall


How to Maintain a Dry Basement in Chicago this Fall

Despite all the jokes about the seasons of the year in Chicago, there really are four.  Sure, sometimes spring and fall are a long time coming and may not last very long but they do exist here and they bring with them some characteristic weather that can determine whether or not basements stay dry.

Fall in Chicago may be hot, may be cold or may be both – sometimes in the same day.  Pretty predictable, though, is that two things are going to be falling – leaves and rain.  Both of these natural phenomena play a part in creating wet basements in Chicago homes and both need to be managed, along with several other factors, to keep Chicago basements dry.

How Do I Keep my Chicago Basement Dry this Fall?

For a Chicago homeowner who wants to do everything he or she can to keep a basement dry when fall rains hit, the key is preparation and that starts in late summer.  There are a number of things a homeowner can do or have done that will go a long way toward keeping water out of the basement.

Extend Downspouts – Water that ends up in the basement starts out in the ground.  Some of that is always going to be there and some of it will soak in during periods of heavy rain but there’s no reason to make it worse by allowing downspouts to dump water right next to the foundation.  Because of the way a typical new foundation is excavated, the ten-foot space around a home is particularly vulnerable to saturation.  When downspouts just end at the corners of a home, all the water shed by the roof during a rain gets concentrated in this area and will likely end up in the basement.  Extending downspouts more than ten feet away from the foundation will decrease the likelihood of this happening; running the extensions underground will eliminate unsightly surface piping and leave the extensions far less subject to disturbance by landscapers, high winds and neighbors’ kids.

Clean Gutters – Extended downspouts are very helpful in maintaining a dry basement but if the gutters that drain into them are clogged with debris, the water will sheet over the edge of the roof and never reach the downspouts.  Instead, it will end up in that 10-foot “zone of failure” that surrounds the foundation.  Prepare for falling leaves by cleaning out spring and summer debris and making sure gutters are solidly attached and not leaking.  A one-inch rainfall on the typical Chicago home can produce as much as 1500 gallons of water; keeping gutters clean will direct that water where it belongs, not into the basement.

Check Window Wells – Window wells allow air and sunlight into the basement but they can also allow water in when they are not properly maintained.  Check to make sure that window well liners are securely attached to the foundation and that wells themselves are free of debris such as lawn clippings, weeds and trash.   If the window well has a drain, make sure it is clear; if not, consider having one installed to avoid having the basement window turn into an aquarium with the first downpour.  All window wells should have a durable cover to keep the crud out, not a flimsy plastic “bubble” from the big box store.

Gutter cleaning can be done by a homeowner, handyman or gutter service but designing and installing downspout extensions, window wells and covers is best done by an expert at keeping basements dry – a basement waterproofing contractor.  At U.S. Waterproofing, we have the experience and expertise, not only at keeping water out of a basement but at preventing it from returning if it happens – our more than 300,000 satisfied customers can vouch for that.  Why not ask for our free advice before fall arrives?
