"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."

★★★★★
"The experience working with BAM basements was very positive! They recommended ways to improve our basement. Very knowledgeable and professional! Completed in timely manner! Great improvement to our home!"
★★★★★
"I've put off getting my basement waterproofing for many years. If only I had reached out to B.A.M! the first time my basement flooded. Excellent experience all around. From receiving my initial quote to coming home after the work to a dry basement that looks better than ever. Great people, service and craftsmanship."
★★★★★
"I had B.A.M.! replace a basement wall, secure the foundation, and stop the water leaking into my garage — some heavy-duty work. These guys expect the unexpected when it crops up and adapt to get the job done. Don't hesitate — these are the kind of honest people who obviously care about the quality of work they do."
★★★★★
"Eric inspected my foundation and quickly located the issue. He gave me my options for addressing the issue and BAM quickly worked around my schedule to ensure the issue was addressed. Honest and very professional — did not try to fix anything that did not need fixed!"
★★★★★
"The service is extraordinary beginning with the sale process. The follow up to all preparations and details is professional and thorough. The most impressive people were the crew who installed my new window wells. They were very courteous and professional."
★★★★★
"Thank you B.A.M.! for your great service. We just had our egress window replaced and your crew was the best. I appreciated that they came out a few days before the job was to be done to double check things and to make sure that everything went smoothly. I would not hesitate to use your services again."
★★★★★
"Egress Installation. Above and beyond all of our expectations!! The office staff was great. Scheduling was super quick. The guys who came from inspection, digging and installation were so amazing!! They were quick, friendly and clean!!"
★★★★★
"Thank you B.A.M.! for your great service. My driveway was a cracked up mess but they managed to straighten most of it out. The foam pillars under the foundation of my addition lifted it enough to make the windows open easier. There was little to clean up after they were done. I would use them again."
★★★★★
Commercial Project
"BAM raised the floor at St John Lutheran Church. They did a great job from determining the correct solution to the completion of the job. Nicholas suggested we include TE Forensic engineering to confirm it was the floor and not the foundation that was sinking. TJ was always available to answer our questions and get the project scheduled to fit our needs, including sending 2 crews! Tim and Hunter knew exactly how to get the floor raised without issues and perfect cleanup when done!"

"Neil, PJ and Tyler were prompt, friendly and efficient. They did a nice job of explaining the process and answering all my questions."

Read All 258 Google Reviews ↗Why BAM Basements Has a Perfect 5-Star Rating
A 5-star reputation is not built with marketing. It is built one honest job at a time. Here is what drives BAM's perfect rating across 258 reviews:
01
Honest Assessments
BAM technicians will tell you if you do not need a repair. Multiple reviewers specifically mention that BAM saved them thousands of dollars by recommending a less expensive solution — or no solution at all. That honesty is rare in the home services industry, and it is why customers return and refer.
02
Lifetime Transferable Warranty
BAM is one of the only basement companies in Iowa that offers a Lifetime Warranty that transfers to a new property owner. This is not a marketing claim — it is a structural commitment backed by 13 years of standing behind every job. When you sell your home, the warranty goes with it.
03
Crews That Respect Your Home
Reviewers consistently mention crew professionalism, cleanliness, and communication. BAM crews explain what they are doing, why they are doing it, and what to expect. They clean up completely before leaving. This is the standard, not the exception.
04
New Methods and Materials Only
BAM does not use outdated techniques. Every waterproofing system, every foundation repair method, and every concrete lifting process uses the most current materials available. This is why BAM can offer a Lifetime Warranty — they are not patching problems, they are solving them permanently.
