Our Basement Waterproofing Process

Here's Exactly What We Do

First, we inspect your basement to identify exactly where water is entering and why. This isn’t guesswork – we need to understand the source before we can solve the problem permanently.

Next, we address any existing cracks or damage in your foundation walls. These get properly sealed with professional-grade materials that can handle the pressure and movement that comes with settling and seasonal changes.

Then we apply the appropriate waterproofing system for your situation. This might involve interior sealing, exterior waterproofing, or drainage solutions like sump pump installation. The approach depends on your specific water issues and your property’s layout.

Finally, we test everything to make sure water stays out. You’ll know exactly what we did and how to maintain your newly protected basement.

The cost of basement waterproofing depends on several factors: the size of your basement, the extent of current water damage, and which waterproofing methods your situation requires. Interior sealing projects typically start around $3,000-$5,000 for smaller basements, while comprehensive exterior waterproofing can range from $8,000-$15,000 or more for larger homes with significant drainage issues. The investment makes sense when you consider the cost of dealing with repeated flooding, mold remediation, or foundation repairs down the road. We provide detailed estimates after inspecting your specific situation, so you know exactly what you’re paying for and why.
Interior waterproofing works from inside your basement and focuses on managing water that’s already trying to enter. This includes sealing cracks, applying waterproof coatings to walls, and installing drainage systems or sump pumps to handle water collection. Exterior waterproofing addresses the problem at its source by creating a barrier on the outside of your foundation walls and improving drainage around your home’s perimeter. Exterior methods are often more comprehensive but require excavation around your foundation. The right approach depends on your specific water issues, your property’s layout, and your budget. Sometimes a combination of both methods provides the most effective long-term solution.
Most interior basement waterproofing projects take 2-4 days to complete, depending on the size of your basement and the extent of the work needed. This includes crack repair, surface preparation, and application of sealers or coatings. Exterior waterproofing projects typically take 5-7 days because they involve excavation, foundation work, and proper backfilling around your home. Weather can affect exterior work timelines, especially during New England’s wet seasons. Sump pump installation usually adds 1-2 days to any project. We’ll give you a realistic timeline upfront and keep you informed if anything changes during the work.
Professional waterproofing dramatically reduces your risk of basement flooding, but the level of protection depends on the methods used and the severity of water issues around your property. Interior waterproofing with proper drainage and sump pump systems can handle most typical water intrusion from rain and snow melt. Exterior waterproofing provides more comprehensive protection by preventing water from reaching your foundation walls in the first place. However, extreme weather events like major storms or rapid snow melts can overwhelm any system. The goal is to protect your basement under normal and moderately severe conditions while giving you proper drainage to handle excess water when it does occur.
Several signs indicate you need basement waterproofing: visible water stains on walls or floors, musty odors that don’t go away, white chalky deposits on foundation walls, or actual water pooling after rain. You might also notice increased humidity throughout your home, mold growth in corners or along walls, or paint peeling from basement walls. Even minor dampness shouldn’t be ignored because it typically gets worse over time, especially in older East Somerville homes. If you’re seeing any moisture issues, it’s worth having a professional assessment. Early intervention costs less than dealing with major water damage or foundation problems later.
Waterproofed basements need minimal maintenance, but a few simple steps help ensure long-term protection. Check your sump pump periodically to make sure it’s working properly, especially before heavy rain seasons. Keep gutters clean and make sure downspouts direct water away from your foundation. Inspect your basement walls occasionally for new cracks or signs of moisture, and address small issues before they become bigger problems. If you have a dehumidifier, maintain it according to manufacturer recommendations. Most professional waterproofing work comes with warranties, so document any concerns and contact us if you notice changes in your basement’s condition.
