Our Basement Waterproofing Process

Here's Exactly What We Do

First, we inspect your basement to find exactly where water is getting in. We check foundation walls, floor joints, window wells, and existing drainage. We’re looking for the real source, not just the obvious wet spots.

Next, we explain what we found and recommend the right waterproofing approach for your specific situation. Sometimes that’s interior sealing, sometimes exterior waterproofing, often a combination. We tell you why we’re recommending what we recommend.

Then we get to work using professional-grade materials and proven techniques. We seal foundation cracks, apply waterproof barriers, install proper drainage where needed, and make sure water has somewhere to go that isn’t your basement floor.

Complete Basement Waterproofing Solutions

What's Included in Our Waterproofing Service

You get a thorough foundation inspection and honest assessment of your water problems. We identify all entry points and explain the best approach for your specific basement and budget.

Our waterproofing work includes crack sealing, foundation wall treatment, and proper drainage solutions. We use materials designed for New England’s freeze-thaw cycles because we know what works in this climate.

We also handle the details that matter – proper grading around your foundation, window well drainage, and making sure your gutters and downspouts direct water away from your house. Water problems usually aren’t just one thing, so we look at the whole picture.

How much does basement waterproofing cost in Waltham?

Basement waterproofing costs vary based on your specific situation, but most Waltham homeowners invest between $3,000 and $8,000 for comprehensive waterproofing. Simple crack sealing might cost less, while extensive exterior waterproofing with drainage systems costs more. The key factors are how much of your foundation needs treatment, whether we’re working inside or outside, and what drainage improvements are needed. We always provide upfront pricing after we inspect your basement, so you know exactly what you’re investing in before we start work.

Should I waterproof my basement from inside or outside?

It depends on where your water is coming from and what’s practical for your property. Exterior waterproofing is often more effective because it stops water before it reaches your foundation walls, but it requires excavation and costs more. Interior waterproofing works well for minor seepage and is less disruptive to install. Many Waltham homes benefit from a combination approach – exterior work where needed and interior sealing for complete protection. We evaluate your specific situation and recommend the approach that makes the most sense for your basement and budget.

Will waterproofing my basement prevent all future water problems?

Professional waterproofing should eliminate your current water intrusion problems when done correctly. However, your foundation and drainage system need occasional maintenance just like other parts of your home. We use proven materials and techniques that last for decades, but things like settling, new cracks, or drainage issues can develop over time. The good news is that proper waterproofing dramatically reduces your risk of water problems and makes any future maintenance much simpler and less expensive than dealing with ongoing leaks.

How long does basement waterproofing take to complete?

Most interior waterproofing projects take 1-3 days depending on your basement size and the work needed. Exterior waterproofing typically takes 3-5 days because of excavation and proper curing time for materials. Weather can affect exterior work timing, especially during Waltham’s wet seasons. We schedule your project to minimize disruption and keep you informed about timing throughout the process. The actual timeline depends on your specific basement conditions, but we always give you realistic expectations upfront so you can plan accordingly.

What causes basement water problems in Waltham homes?

Waltham’s clay soil doesn’t drain well, so water sits against foundation walls longer after rain or snow melt. Many homes here were built before modern waterproofing standards, so foundations weren’t properly sealed originally. Seasonal freeze-thaw cycles create and expand foundation cracks over time. Poor drainage around the house – like clogged gutters, improper grading, or missing downspout extensions – also contributes to basement moisture. The combination of older foundations, challenging soil conditions, and New England weather creates the perfect storm for basement water issues.

Can I use my basement right after waterproofing is finished?

You can usually use your basement normally within 24-48 hours after interior waterproofing, once materials have properly cured. For exterior work, we need to backfill and restore landscaping, which might take an extra day or two. We recommend waiting a full week before storing valuable items against newly waterproofed walls, just to be safe. If we install new drainage systems or sump pumps, we test everything thoroughly before considering the job complete. The goal is making sure your basement is completely ready for normal use without any risk of moisture problems returning.
