Steel Foundation Support & Epoxy Injection System
If your foundation walls are bowing or leaning inward, our wall support systems stop the movement now — and can gradually restore your wall toward its original position over time.
A bowing foundation wall is one of the most urgent problems a homeowner can face. As soil pressure pushes inward — accelerated by water saturation and freeze-thaw cycles — your wall is actively moving. Every inch it bows makes repair more expensive and more complex. 207 BulletProof Basement’s steel beam and Epoxy injection systems are engineered to fix cracks and halt that movement immediately and, over time, can actually restore the wall toward its original position.
The right system depends on the severity of the bowing, the type of foundation material, and the available space on your property. We evaluate each situation individually and recommend the method that delivers the most durable result for your specific conditions.
Immediately halts active inward movement — no more waiting and watching it get worse
Steel I-beams can be tightened over time to gradually restore the wall toward plumb
Systems are engineered for Midcoast Maine’s specific soil and frost conditions

Crawlspace Encapsulation
A damp, exposed crawlspace is one of the most common causes of moisture problems in a home. Ground vapor rises constantly, bringing humidity, musty odors, and the conditions for mold and wood rot. In Maine, this is made worse by seasonal moisture, snowmelt, and temperature swings. Left untreated, that moisture doesn’t stay below—it affects your floors, air quality, and even structural components over time.
207 BulletProof Basement’s crawlspace encapsulation systems are designed to fully seal the space using heavy-duty vapor barriers, air sealing, and proper drainage when needed. By isolating the crawlspace from the earth and outside air, we stop moisture intrusion and stabilize the environment beneath your home.
The right approach depends on the condition of the crawlspace, existing moisture levels, and how air and water are moving through the space. We evaluate each crawlspace individually and recommend a system that delivers long-term protection and a cleaner, healthier home above.
Full crawlspace inspection to identify moisture and air leaks
Ground leveled and prepped, with drainage if needed
Heavy-duty vapor barrier installed over floor and walls
All seams, vents, and penetrations fully sealed to lock out outside air and moisture
Dehumidification or conditioning is added if needed to maintain a dry, stable environment

"Our 1890s farmhouse had serious water intrusion every spring. We tried two other companies. Conor diagnosed the real problem in 20 minutes and fixed it permanently. Dry basement for three years now."

Frequently Asked Questions
Not sure what’s going on with your basement or crawlspace? Start here—these are the questions most homeowners ask before getting started.
-
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.
