Trusted Waterproofing Professionals Protecting Homes Across the USA

When water finds its way into your home or commercial building, the consequences can be devastating. Structural damage, mold growth, ruined belongings, and compromised air quality are all too familiar to property owners who waited too long to act. At Koppers Waterproofing, we built our entire operation around one mission: stopping water intrusion before it causes irreversible harm.

Our team of licensed and insured waterproofing specialists brings hands-on expertise to every project we take on. We are not a call center dispatching random contractors. We are trained professionals who understand how water moves through soil, how hydrostatic pressure builds against foundation walls, and how the local climate in different parts of the country creates unique moisture challenges. That knowledge shapes every recommendation we make and every system we install.

We serve homeowners, commercial property managers, real estate investors, and contractors nationwide. Whether you are dealing with a leaky basement that floods every time it rains, a crawl space filled with standing water, or a commercial structure showing signs of foundation moisture, our diagnostic process gets to the root cause rather than just treating the symptoms. We believe in doing the job right the first time, which is why our workmanship stands behind a solid guarantee.

Reaching out to Koppers Waterproofing means you get a team that communicates clearly, shows up when promised, and explains exactly what we are doing and why. No pressure tactics, no inflated scopes of work, and no surprise charges when the job is done. We take pride in the relationships we build with property owners across the country, and most of our business comes from referrals because we treat every home as if it were our own.

  • Fully licensed, bonded, and insured in every state we operate
  • 24/7 emergency response for urgent water intrusion situations
  • Upfront pricing with no hidden fees or post-job surprises
  • Industry-grade materials backed by comprehensive warranties
  • Dedicated project managers from assessment through completion

My basement had been taking on water for three years. I had two other companies look at it and neither of them gave me a straight answer. Koppers Waterproofing came out, diagnosed a failed exterior membrane in one visit, and had the whole thing sealed within a week. Dry ever since.

MR
Michael R.
Homeowner

Called at 11pm when I discovered water pouring through a crack in my foundation wall. They answered immediately, talked me through emergency steps, and had a crew at my house first thing in the morning. Professional from start to finish and the price was exactly what they quoted.

SL
Sandra L.
Property Owner

I manage a small commercial strip mall and had persistent moisture issues in two of the units. Koppers Waterproofing assessed all three buildings, gave me a consolidated proposal, and completed everything on schedule without disrupting the tenants. Would absolutely hire again.

How fast can a Koppers Waterproofing technician arrive?
For emergency situations, we aim to have a technician on-site within hours of your call, depending on your location. For standard inspections and non-emergency work, we typically schedule within 24 to 48 hours. When you call, our dispatch team will give you a realistic arrival window based on your area and the current call volume.
Do you provide upfront pricing?
Yes. Every proposal we present is fully itemized. You will know exactly what materials are being used, what labor is involved, how long the job will take, and what the final cost is before any work begins. We do not add charges after the fact. If unforeseen conditions require scope changes, we discuss and get your approval first.
Is your work guaranteed?
Our workmanship is backed by a satisfaction guarantee. If a system we install fails to perform as described within the warranty period, we return and correct the issue at no charge to you. We also use materials from manufacturers who stand behind their products with their own coverage, giving you multiple layers of protection.
What emergency services do you offer?
Our emergency services include active flood containment, water extraction using industrial-grade pumps, emergency crack injection and sealing, sump pump failure response, and temporary protective measures to stop water intrusion while a permanent solution is prepared. We are available 24 hours a day, 7 days a week, including holidays.
How do I know if I need waterproofing?
Common signs include water stains or damp patches on basement walls, a musty smell in the lower level of your home, visible mold or efflorescence on concrete surfaces, peeling paint in below-grade areas, cracks in your foundation walls, standing water after rain, and humidity that seems unusually high. You do not need to wait until you see standing water to call us.
Do you service commercial properties?
Yes. We handle commercial waterproofing for retail buildings, warehouses, multi-unit residential structures, parking structures, and more. Commercial jobs are assigned dedicated project managers to handle scheduling, coordination, and communication throughout the project.
