"Chris and his crew did a great job encapsulating my crawl space. They showed up when they said they would and communication with them was good. They actually did most of the multi-day job while I was gone on vacation, but I was always kept in the loop and given daily updates along with pictures of the progress. Everything they cleared out from under the house was hauled away with no traces left behind. When part of the crawl space access door frame was damaged in the final stages of the project, Chris returned with all materials to restore it and made sure the door was completely sealed. I had several quotes for this job and Crawl Space Jam was more than competitive and did as much, or more, than what some higher bids were going to do. Highly recommend."

"Kendal King came and gave us an estimate on our project, explaining our options and the pros and cons of each way of handling our drainage issues. Friendly, respectful service that I would recommend to Anyone. It was pouring rain on both days and he couldâ ve easily rescheduled- but he worked in the rain and completed project on time."

"I can’t say enough good things about Derrick with Fortress Vapor Solutions. From the first inspection to the final walkthrough, everything was handled professionally and efficiently. He showed me exactly what was going on in my crawlspace with pictures and explained it in a way that actually made sense. The work itself was outstanding—clean, thorough, and done right the first time. The encapsulation completely transformed my crawlspace, and the musty smell in my home is completely gone. You can tell he takes real pride in what he does. What really surprised me was the price. After getting a couple other quotes, I was expecting to pay a lot more for this kind of work. Derrick came in very fair without cutting any corners, which made the whole decision easy. If you’re dealing with moisture or crawlspace issues, do yourself a favor and call Fortress Vapor Solutions. Honest work, great results, and pricing that actually makes sense."

Basement Waterproofing questions, answered by experts

Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.

Standing water under your house can threaten its structural integrity. If water pools in your crawl space, it can damage the foundation and the structure above ground, causing wood rot, mold, and other problems. If you have a concrete foundation, standing water under your house can also make your foundation slabs crack.

A vapor barrier keeps moisture out of the crawl space, while insulation reduces the amount of unconditioned air—and sometimes moisture—that enters the space. Coupling a vapor barrier with insulation can help prevent humidity and related moisture damage in a crawl space while also making your home more energy-efficient. Just be sure to use insulation that won’t get damaged from moisture, like rigid foam board or expanding spray foam insulation.

A crawl space can be as little as 42 inches below the grade of your house, but this is not always recommended in flood-prone areas. At a minimum, there must be at least 16 inches of clearance between the ground and the floor joists to access the space in an emergency.

The most challenging part of finishing a basement is addressing moisture control. Basement waterproofing is an essential task that requires a professional’s skills and knowledge. If you don’t properly waterproof your finished basement, it’ll be vulnerable to dampness, water damage, and mold growth. Ensuring proper insulation and ventilation to combat these issues while meeting building codes adds complexity to your remodeling project.
