Egress Window Installation Experts in Johnston
BAM has served Johnston and Polk County since 2012, installing safe, code-ready egress windows that protect families and property. Johnston sits on clay-rich soils and experiences freeze-thaw cycles that can undermine window wells and foundation openings, so proper drainage and waterproofing are essential. Our crews evaluate soil, grade, and existing foundation conditions before recommending a solution tailored to your home. Every installation includes our lifetime warranty for lasting performance and peace of mind.
How BAM Installs Egress Windows in Johnston
We begin with a site assessment to locate utilities, check sill height, and confirm egress dimensions for safety and code compliance. Next we excavate a window well, install a corrosion-resistant well and ladder, and integrate a sealed window unit with a waterproof membrane and proper flashing to the foundation. Drainage is tied into a rock bed or the home's existing drainage system, and we backfill with free-draining material to reduce hydrostatic pressure. Finally we restore exterior grade and finish the interior jamb and trim so the new egress looks and functions like part of your home.
Johnston homeowners need egress window upgrades because Iowa's heavy clay soils hold moisture and expand, increasing the risk of water intrusion and settling around old openings. Freeze-thaw cycles can widen gaps and cause leaks if wells and seals are not properly installed and drained.

Frequently Asked Questions — Egress Window Installation in Johnston, Iowa
Permits are commonly required in Johnston and Polk County for egress window openings because they affect emergency egress and structural openings. BAM handles permit paperwork and coordinates inspections with local authorities so your project meets city requirements.
Most residential installs in Johnston take one to three days, depending on soil conditions, well size, and whether foundation modifications are needed. Scheduling can vary seasonally—spring and fall fill quickly—so we recommend booking a free estimate to confirm timing.
Cost varies with opening size, well type, soil and drainage needs, and interior finishes; we provide transparent, itemized estimates after inspection. Every BAM egress window installation comes with a lifetime warranty on waterproofing and workmanship for the life of the repair.
Look for water staining, dampness, mold, standing water in the well, cracked concrete, or a window that sticks—these are common in homes built on Iowa's clay soils. Early fixes prevent larger foundation and interior moisture problems caused by swelling clay and freeze-thaw damage.
