Pricing & Dispatch Questions
Common questions about Des Moines estimates, scheduling, and scope options.
Is Des Moines Window Well Covers the manufacturer that installs the covers?
No. Des Moines Window Well Covers is an independent local referral and dispatch service. When you submit a request, we route your project details to one vetted window well cover and egress specialist serving the Des Moines Metro who contacts you directly.
How much weight can a custom polycarbonate window well cover hold?
Unlike $30 hardware-store plastic bubbles that crack under 15 lbs of snow, custom 1/4-inch and 3/8-inch UV-stabilized polycarbonate covers reinforced with anodized aluminum ribs are rated to support 400 to 500 lbs of distributed load, keeping children, pets, and lawn crew safe.
Are covered egress window wells legal under Iowa building code?
Yes, provided the cover can be opened fully from inside the well by a child or adult without a key, tool, or excessive force (IRC Section R310). All bedroom egress covers installed by local specialists use interior quick-release pins or hinged escape hatches.
Will a sloped cover stop rainwater from leaking through my basement window?
A sloped cover with a sealed foundation backplate diverts 95%+ of roof splash and direct rainfall away from the well. If hydrostatic groundwater is rising from beneath the well, the specialist can also clear the vertical footing drain and replace silted gravel.
Do you cover West Des Moines, Ankeny, Waukee, Urbandale, Johnston, and Ames?
Yes. We route measurement and installation requests across Des Moines, West Des Moines, Ankeny, Waukee, Urbandale, Johnston, Clive, Altoona, Norwalk, and Ames.
