I Have Water In My Basement
Andersen's Waterproofing uses time-tested, expert processes to fix your existing water issues in your basement.
We Work With You! From Start to Finish
As a basement & foundation waterproofing expert for over 37 years & home-building experience for almost 20 years (built over 80 homes), I have experienced an enormous “cry” from homeowners, who have water issues with their basements, even while construction was still going on.
A. Andersen Homes: Building Smart, Saving You More
As both a home builder and homeowner, I understand the challenges of rising land, material, and labor costs. The housing affordability crisis is real, and every dollar counts when building or remodeling your home. That’s why A. Andersen Homes is committed to helping you make the most of your investment—ensuring your hard-earned money is spent wisely.
Built for Strength & Longevity

With over 38 years of waterproofing expertise, we go beyond standard construction practices to ensure your home’s foundation is built to last. Every new home includes our 30-Year Transferrable Basement Guarantee, giving you peace of mind from day one.
30-Year Basement Guarantee at Closing
Your home’s foundation is the most critical element of its structural integrity. That’s why we include a 30-Year Transferrable Basement Guarantee—a level of protection homeowners and investors have been waiting for.
Lower Overhead = More Savings
We don’t operate out of an expensive showroom or shop, which means lower overhead costs—and we pass those savings directly to you.
Direct Buyer to Supplier Savings
Every homeowner works directly with our trusted suppliers, vendors, and subcontractors. That means you get the best possible pricing—the same builder’s discounts we receive—saving you thousands, sometimes even tens of thousands of dollars.
Transparent & Affordable Pricing
Unlike traditional builders who mark up costs significantly, we only charge 6%–12% (depending on the complexity of your home) based on the actual project costs. This straightforward approach ensures you get maximum value without hidden fees or inflated prices.
Superior Foundation & Drainage
Most builders follow state code by backfilling with only 12”–18” of stone and existing soil, which can put excessive pressure on your foundation, leading to cracks and structural damage. We take a different approach—hauling away all excavation debris and replacing it with 70%–80% washed clear stone and 20%–30% pulverized black dirt. This dramatically improves drainage and protects your home from long-term issues.
