Basement waterproofing is the process of preventing water from entering your basement or foundation. This can be done from the inside using systems like French drains, sump pumps, and interior drainage channels, or from the outside by sealing the foundation and installing proper drainage to keep water away from the structure. When we come out to give you your free inspection, we will inform you of your options and which is best for your basement’s specific issues.

A properly installed waterproofing system is designed to last for decades. Interior systems like drainage channels and sump pumps can perform reliably long-term with basic maintenance, while exterior waterproofing (membranes and foundation sealing) is built to provide long-lasting protection against groundwater intrusion. Every installation we do comes with a transferrable lifetime warranty, so you can rest assured that your basement will be dry and safe for decades to come.

In most cases, yes. Waterproofing is especially important in Midcoast Maine due to high water tables, seasonal snowmelt, and frequent rainfall. Many homes experience moisture issues over time, so having a proper waterproofing system helps prevent damage, mold growth, and structural problems.

We provide both interior and exterior waterproofing systems. Interior solutions include French drains, sump pumps, and drainage channels to manage water that enters. Exterior solutions involve excavation, foundation sealing, and perimeter drainage systems that stop water before it reaches your foundation.

Costs vary depending on the size of the basement, severity of the issue, and the solution required. Smaller interior systems may cost a few thousand dollars, while full exterior waterproofing projects can be more significant due to excavation. We provide straightforward estimates after evaluating your property.

Common signs include standing water, damp walls or floors, musty odors, mold growth, efflorescence (white powder on walls), or cracks in the foundation. Even minor moisture can indicate a larger issue, so it’s best to address it early before it leads to more expensive damage.
