"From the first visit to my home from Sean for an estimate, to the crew that arrived to do the project I was impressed. Everyone was extremely professional. The crew arrived on time, the crew leader introduced me to the rest of the crew and explained how they would proceed with the project. They protected the work spaces with plastic from my garage to the crawl space opening in side my closet. They went to work and kept me informed about the progress. The whole crew worked very efficiently and got the project done in one day. They left work area spotless when they were done. I would highly recommend this company for any waterproofing project!!"

"Overall the Crawlspace Crew did some great work for our basement area. The initial phone call was very informative, then they came on-site for a walk-thru and provided an itemized estimate we could understand. We expressed that budget was a concern and only elected to do some of the work, they were supportive of this and we were scheduled in within a week. The work was completed in a timely and thorough manner and we are very satisfied. Shout out to Dillon, for working within our budget, and being flexible on the specifics, I would definitely recommend this company/service to a friend or anyone in need."

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.

Installing a bathroom in a basement isn’t a project for most homeowners. Many parts—plumbing, electricity, and carpentry—go into this project, each requiring expert-level knowledge and tools. One miscalculation can lead to very expensive repairs. Plus, some homeowner’s insurance might not pay for damages caused by a homeowner DIYing this project. You can protect yourself by allowing the pros to complete this job for you. 

You should plan on waiting at least a year and ideally two to three years after construction before finishing your basement. This will give the foundation time to settle in response to the weight of your home and the expansion of the surrounding soil. You can then repair your foundation and seal any cracks as needed before finishing it to reduce your risk of future leaks or other issues.

A sump pump can remove excess moisture from under a house if standing water is present. Other ways to protect your crawl space from moisture include installing a vapor barrier, using a dehumidifier, installing insulation, and using a fan to dry the space. Finally, keeping your gutters clear of debris and positioning your downspouts away from the home’s foundation can prevent moisture from getting into the crawl space in the first place.

One handy thing about whole-house dehumidifiers is, once installed, you don’t have to worry about placement or changing the dehumidifier’s position. But if you are using a portable dehumidifier, we suggest keeping it away from walls, vents, and furniture. It needs a central, unobstructed spot with access to lots of air to do its job.
