Basement Waterproofing in Portland, Biddeford, Kennebunk and Southern Maine
Basements throughout Southern and Central Maine face moisture from heavy rain, spring snowmelt, changing groundwater levels, freeze-thaw cycles, and drainage systems that direct water too close to the foundation. Conditions can vary significantly from one property to another, so the water source should be identified before a waterproofing system is recommended.
Basement Improvements serves homeowners throughout York and Cumberland counties, as well as surrounding Maine communities. Our team evaluates the basement, foundation, drainage, sump system, and visible moisture patterns to determine which repairs are necessary and which concerns can continue to be monitored.
Not Sure Where the Water Is Coming From?
A wet basement does not always require the largest or most expensive waterproofing system. The right solution depends on how the water is entering, how often the problem occurs, and which parts of the basement are affected.
Schedule an inspection with Basement Improvements to identify the source of the moisture and understand your repair options.
COMMON BASEMENT ISSUES AND WATER DAMAGE RISKS
MOLD GROWTH
A telltale sign of moisture problems is the presence of mold in your basement. Mold thrives in damp, dark environments, indicating excessive moisture.
Beyond property damage, it poses health risks by deteriorating air quality, potentially causing respiratory issues among household members.
WATER INTRUSION
Finding water in your basement isn’t just an inconvenience; it’s a symptom of a potential breach in your home’s defenses against moisture.
Water intrusion can lead to structural damage, ruin personal belongings, and create an environment conducive to mold and mildew growth.
FOUNDATION CRACKS
Visible cracks in your foundation can be alarming signals of structural stress. They are often caused by water seepage or soil movement beneath your home.
Structural cracks not only compromise the integrity of your foundation but also provide pathways for water to enter, exacerbating moisture issues.
TAILOR-MADE SOLUTIONS FOR BASEMENT WATERPROOFING
SUMP PUMPS
Sump pump systems are the heart of any proper waterproofing system. They move excess water from beneath the concrete slab (floor) and pump it outside.
Sumps operate automatically around the clock so you can sleep easy knowing it’s working hard to keep your basement dry night and day. For even more peace of mind, you can add additional pumps and battery backup pumps for protection during power outages.
DEHUMIDIFIERS
Lots of New England basements can benefit from a professional-grade dehumidifier. This can be thought of as a finishing touch to your waterproofing system.
Pulling any remaining moisture out of the air, a dehumidifier creates a comfortable environment that combats mold growth and musty odors. Our dehumidifiers operate automatically so you’ll have no more pesky buckets to dump.
DRAINAGE SYSTEMS
If the sump is the heart of the waterproofing system, then our Guardian perimeter drain can be considered the veins. Guardian carries water from all corners of the basement to the pump ensuring that the entire basement remains dry.
We offer an industry-leading “lifetime of the structure” warranty on our full waterproofing systems. Confidence is key and you can feel confident because we always stand behind our work.

FREQUENTLY ASKED
QUESTIONS
What are the signs that a basement needs waterproofing?
Common signs include standing water, damp walls or floors, musty odors, peeling paint, white mineral deposits, visible mold, and water entering after heavy rain or snowmelt. A frequently running sump pump may also indicate that the current drainage system is struggling to manage the amount of water reaching the basement.
Why do Maine basements develop water problems?
Heavy rainfall, spring snowmelt, freeze-thaw cycles, poor grading, foundation cracks, and high groundwater can all contribute to basement moisture. The cause should be identified before a repair is recommended because water can enter through several different areas.
How does professional basement waterproofing work?
The solution may include an interior drainage system, sump pump, battery backup, dehumidifier, crack repair, vapor barrier, or exterior drainage improvements. The right combination depends on where the water is entering and the condition of the basement.
How much does basement waterproofing cost in Maine?
The cost depends on the basement’s size, the source and severity of the water problem, and the system required. An inspection is needed before an accurate recommendation and estimate can be provided.
Can I waterproof my basement myself?
Simple maintenance such as cleaning gutters and extending downspouts may help with minor drainage issues. Recurring water, leaking cracks, standing water, or foundation movement should be professionally inspected so the underlying cause is not overlooked.
