Window Well Covers and Drainage in South Bend

Window well covers and drainage are the two things that keep an egress well from becoming a basement flood. We install clear polycarbonate covers ($150 to $600) that shed South Bend’s snow and leaves while opening from inside, and we repair or build well drainage ($300 to $1,000): gravel beds, tie-ins to the footing drain tile or sump, and dry wells dug below frost depth for houses that have neither. Both are included on every new well we set; both are available on wells somebody else set.

The South Bend water problem, specifically

Three facts explain most of the flooded wells we see.

The snow. On the 1991 to 2020 normals, South Bend averages 64.5 inches of snowfall a year: 13.7 inches in December, 21.6 in January, 16.1 in February. That is lake-effect, Lake Michigan sitting 20 miles to the northwest and rarely freezing over. A window well is a bucket that fills with drifting snow all winter and melts in a hurry in March, when the ground beside it is still frozen and cannot absorb anything. The National Weather Service calls mid-winter through early spring the wettest stretch of the year here.

The ground. The Indiana Department of Natural Resources describes the South Bend and Mishawaka area as surface sand and gravel over a clay and glacial till layer 20 to 100 feet thick, with thick clay locally under both cities. Water runs down through the sand fast and stops on the clay. A well bottom that sits at or near that transition is exactly where the water pools.

The river. The U.S. Geological Survey notes that depth to water in the St. Joseph aquifer system is small and that groundwater flows toward the St. Joseph River. Along the Near Northwest, Keller Park, River Park, and the Mishawaka riverfront, the water table itself can rise into the well during a wet spring.

What the code says about drainage

Section R310.2.3.2 of the 2020 Indiana Residential Code requires window wells to be designed for proper drainage by connecting to the building’s foundation drainage system (the footing tile required by R405.1) or by an approved alternative method. There is an exception for foundations on well-drained sand and gravel soils, Group I in the Unified Soil Classification System.

Some Michiana lots genuinely qualify for that exception, particularly on the sandier ground north of the river. Many do not, and the ones that look like they do are the dangerous ones: sand at the surface, clay at four feet. We do not rely on the exception. Every well gets an outlet.

How we drain a well

Tie-in to footing drain tile. The best case. Most South Bend houses from the 1950s on have a perforated drain loop at the footing that runs to a sump. We dig to it, add a perforated drop from a gravel bed under the well, and connect. The well drains the way the foundation does.

Tie-in to the sump line. Where the tile is silted shut but the sump is working, we run a dedicated line from the well bed to the sump crock. Common in 1920s and 1930s houses that got a sump added in the 1980s or 1990s.

Dry well. Where there is no tile and no sump, the usual situation in the Near Northwest, Sunnymede, and River Park houses that predate footing drains, we dig a gravel-filled pit below the 36-inch footing depth Indiana’s code table sets for St. Joseph County, sized to hold and slowly release a lake-effect melt. On clay this is what makes the difference; the gravel volume is the storage.

Gravel bed and fabric. Under every well, whichever outlet we use: washed stone over filter fabric so silt does not clog the bed in five years.

Grading. The well should not be the low point of the yard. We backfill in lifts and slope the surface away from the house. A surprising number of “well leaks” are really downspouts dumping next to the well.

Covers

A cover keeps snow, leaves, mulch, and small animals out of the well, which is most of what clogs a drainage bed. In South Bend a cover is the difference between a well that holds a foot of packed snow and one that holds none.

What we install:

• Clear polycarbonate, bubble or flat, so the window still gets light.
• Sized to the well, sitting on the rim or clipped to it, with a snow load rating that means something in Michiana.
• Openable from inside without tools or a key. The 2020 Indiana Residential Code requires that bars, grilles, covers, and screens on an egress opening be releasable or removable from inside without keys, tools, or excessive force. A cover screwed down from outside turns an escape route into a trap, and it fails an inspection.
• Load-rated so a child or an adult stepping on it does not go through.

Standard sizes are the low end of $150 to $600. Deep wells, oversized walkout-style wells, and composite wells with odd geometry get custom-fit covers at the high end.

Signs your well needs this work

• Water line or silt stain inside the well after a thaw
• Rust-through or bowing on a corrugated well
• Efflorescence or damp drywall on the basement wall below the window
• A sump that runs constantly in March while the well is full
• Snow packed into the well all winter with no cover
• Mulch or leaves filling the bottom of the well

Any of those is a reason to book the free measure. Drainage repair on an existing well is often a same-week job in season. Full well replacement, if the steel is gone, is covered on the window well installation page, and a new egress opening comes with all of this built in on the egress window installation page.

Where we work

South Bend, Mishawaka, Granger, Osceola, Elkhart, and Goshen. Drainage work needs thawed ground, roughly April through November. Covers install any month. Prices are on the pricing page.
