“Jeremy came out to do an estimate today and probably saved us $40k based on previous estimates. He was knowledgeable, honest and direct. He chose to tell us the truth instead of selling us something. We are very appreciative.”
“Thank you B.A.M.! for your great service. The crew showed up on time and worked their butts off. My driveway was a cracked up mess but they managed to straighten most of it out. I would use them again.”
“BAM raised the floor at St John Lutheran Church. They did a great job from determining the correct solution to completion. TJ was always available to answer our questions. Tim and Hunter knew exactly how to get the floor raised without issues and perfect cleanup when done!”

Common questions from Iowa homeowners about basement waterproofing and foundation repair
Iowa basements commonly face water seepage due to hydrostatic pressure from the state’s clay-heavy soils, foundation cracks from expansive soil movement, and mold growth from humidity. The freeze-thaw cycles of Iowa winters accelerate these problems significantly each year.
The cost of basement waterproofing in Iowa typically ranges from $3,000 to $15,000 depending on the severity of the problem, the size of the basement, and the method required (interior drain tile, exterior waterproofing, or sump pump installation). A professional inspection is needed for an accurate estimate. BAM provides free estimates.
Common signs include cracks in basement walls (horizontal, vertical, or stair-step), bowing or leaning walls, sticking doors and windows, uneven floors, and gaps around window and door frames. Exterior signs include cracks in brickwork or chimney separation from the house.
Yes. Iowa building codes require egress windows in basement habitable spaces (like bedrooms) to provide an emergency exit. Specific requirements include minimum opening size, sill height, and window well dimensions per IRC Section R310. BAM installs all egress windows to full code compliance.
The best approach for a wet basement in Des Moines typically combines interior drain tile, a high-quality sump pump with battery backup, crack sealing, and proper exterior grading. A professional assessment is crucial to identify the root cause and the most cost-effective solution for your specific home.
