"We are the 2nd owners of a 15 year old home. Don't know why the original owner/builder did not put a sump pump in the basement, as it would have been a cheaper option in the end. If you are building a new home with a basement, put a sump pump in, don't scrimp on what is a very valuable insurance policy. After looking at a handful of other companies to retrofit a sump pump in our cellar, we picked All Aspects Waterproofing, LLC. They did a great job! Very high quality work, and outstanding service. They did a great job! We enthusiastically recommend All Aspects Waterproofing to any homeowner!"
