Real People, Honest Reviews

“Vincent and his team were knowledgeable, timely, and highly professional while fixing the drainage in our yard. Vince came out several times prior to starting the work to ensure the measurements were correct and the job would go on smoothly. During the actual work, Vincent and the team worked quickly and efficiently to get it done. Our yard is now covered in beautiful grass (that they seeded and laid the straw) and no longer floods. Thank goodness for Koppers Quality Waterproofing!!”

I highly recommend Koppers Quality Waterproofing for your waterproofing needs. The folks there are professional, prompt, and have considerable knowledge. Tony came out and gave me a fair estimate and within a few days my sump pump has been installed and now I have peace of mind again! They are courteous and patient and they gave me a lifetime transferable warranty! Overall experience was exceptional which prompted me to write a review. Great job guys and thank you!
