Why this pattern is common
Hail is a regular part of early summer along the Front Range. Besides denting cars and roofs, it fills gutters with ice and shredded leaves in minutes. Water that cannot get through the gutter goes over the edge, and on many houses that means straight down beside the foundation. In older neighborhoods where backfill has settled and the ground slopes toward the house, one storm can deliver a surprising amount of water to a single basement wall.
The situation
Illustrative example. Not a real job or customer.
A hypothetical 1950s ranch in south Englewood has a finished basement family room with carpet and paneled walls. A short, intense June hailstorm passes through in the late afternoon. That evening the owners notice the carpet along the north wall is wet about a foot out from the paneling.
- The owners check the floor drain and laundry area, find them dry and conclude water came through the wall.
- They pull back the carpet and find the pad soaked along the whole north wall, with white residue on the concrete at the base of the wall.
- A waterproofing salesperson visits the next day and recommends an interior drain system along every wall.
- Before deciding, the owners walk outside during the next rain and see water sheeting over the north gutter, which is still packed with hail debris, onto soil that slopes toward the house.
- They clean the gutter, add a downspout extension and rebuild the soil slope along that wall. A cleanup provider removes the wet pad and dries the slab and the paneled wall cavity.
Through the rest of the summer, including two more heavy storms, the north wall stays dry. The owners decide against the interior drain system and keep a note to clear gutters after every hailstorm.
What went right and what could have gone better
| Went right | Could have gone better |
|---|---|
| Checking the floor drain first ruled out a sewer backup | Gutters had not been checked after the storm |
| Pulling back the carpet showed how far water had spread | The settled soil slope had been noticed years earlier but not fixed |
| Watching the house in the rain revealed the true source | Paneling over bare concrete hid the wall condition |
| Getting the slab dried before relaying carpet | Nearly signing for a large system before identifying the cause |
