What Our Customers Say

I contracted with Gary for a basement dig-out project where his team lowered the basement floor of a 100 year old home. This was a large project in which Gary’s team worked 10 hours days, 6 days per week over 2-plus months. The work involved removing an existing concrete floor, pouring new reinforced concrete footings, and installing new lolly columns, a drainage system and new concrete floor. New drain pipes and a sewage ejector pump were also installed for a future bathroom. Gary and his crew were knowledgeable and experienced in this type of specialized work. I highly recommend Alliance.

From the initial consultation to the completion of the project, they were incredibly accommodating, ensuring that all of our needs and concerns were addressed promptly and effectively. Their proactive approach to waterproofing solutions gave us peace of mind knowing that our property was in good hands. Not only did they deliver on their promises, but they exceeded our expectations at every turn. If you’re in need of exterior waterproofing services and want to work with a company that is honest, dedicated, professional and truly cares about their clients, look no further.
