"Let me start by saying that I would ABSOLUTELY recommend Weather – Tite Waterproofing to anyone who has water in their basement. They were incredibly professional and did top notch work. I had been getting water in my basement on and off for years. After fixing the gutters and fixing the roof it was time to address the basement. I consulted with three different Angie’s List companies (all very highly rated). Each company had a slightly different price but more importantly a different approach to resolving the problem. I picked Weather – Tite because I was comfortable with the approach that they proposed, and the price was in line with the other quotes. The work took 2 days. Day 1 was spent digging the trenches around the interior of the basement. Day 2 was spent putting in the stones and piping and hooking it all up to the sump pump. As you can imagine, putting in a drainage system is messy work – you would have been none the wiser – my whole house was spotless (including the basement) – no dust anywhere. The work was so professional that I had them come back and put up the baseboard and sheet rock. I can happily say that since the work has been completed, we have had quite a few heavy rains, and my basement has stayed dry."

"First attempt at remediation was disappointing, but subsequently a more aggressive effort was made. I must say I was pleasantly surprised at the level of customer service and concern. In a time when warranties and customer satisfaction are just lip service, it is a refreshing experience to deal with a company that values its customerâ s concerns. I would recommend you consider Once And Done for your basement waterproofing needs.."

Basement Waterproofing questions, answered by experts

Yes, crawl spaces can attract bugs, especially since moisture tends to build up in the space, and moisture attracts pests. A good way to prevent pest infestation in your crawl space is to install a vapor barrier—called crawl space encapsulation—on the interior to seal the space, along with a French drain or some other kind of foundation drainage system outside to keep runoff out of your crawl space. You can also seal foundation cracks and repair damages to cut off access to pests.

You can DIY basement waterproofing in some ways to help save on the overall costs. If your basement isn’t experiencing a lot of water but is noticeably humid, you can try running a dehumidifier that will pull the excess water out of the air. If you notice water leaking due to outdoor drainage issues, you can add downspout extensions to keep rainwater away from your home. 

However, if the problem is more severe and requires a more extensive solution, it’s best to call a basement waterproofing professional to assess the treatment you need and install waterproofing safeguards properly. Since keeping water out of your basement is important, ensuring this job is done correctly the first time is best.

Yes, water coming up from the floor should be treated as an emergency. If you're unable to either identify or stop the source of the water on your own, contact an emergency plumber right away. In addition to harming your flooring, standing or pooled water can lead to water-damaged concrete.

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.

A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can’t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it’s legal to do so.
