Does your waterproofing contractor have a full-service Service Department?

As part of the decision process of hiring a waterproofing or crawl space contractor, the warranty is important, as is making sure that the company has a service department to maintain the system. Most waterproofing contractors in Connecticut offer lifetime warranties, as do we. However, we understand that the best warranty is the one you never have to use -- especially in the case of basement waterproofing. The only time you need to use the warranty is when you get flooded -- exactly what you invested in originally to prevent! A service program from a professional service department can maintain your system through the years to keep it in optimal working order. Make sure that service and an annual maintenance program is a real part of the company's philosophy.
