Community Tips

TipKasa Team

Remove debris and standing water immediately after rain, as stagnant water in window wells attracts mosquitoes and accelerates foundation damage through moisture infiltration. A garden trowel efficiently scrapes out packed sediment and leaf matter that standard vacuums cannot reach.

WarningKasa Team

Never allow window wells to accumulate more than 2 inches of standing water, as this creates hydrostatic pressure that forces moisture through foundation cracks and basement walls. Metal window well covers like those from Bilco ($60-120) prevent debris accumulation and eliminate this risk entirely.

Cost InfoKasa Team

Installing a basic plastic window well drain system costs $15-40 per well and redirects water away from the foundation, preventing the $500-2,000 basement water damage repairs that commonly result from neglected wells. This low-cost preventive step eliminates the need for costly dehumidifiers and mold remediation later. ---
