"Great results from waterproofing. Turned my spring flooding anxiety to calm. As humidity rose in summer, I put in a small dehumidifier. Made basement noisy as it struggled to dry and produced a lot of heat. As temperatures rose to about 83 down there and the humidity rose to over 68%, I had same people put in a whole basement commercial-grade dehumidifier. The small unit dropped the humidity to around 50% in less than an hour. Incredible performance and have me peace of mind and peace and quiet downstairs. Temperature dropped gas as well. Weel worth the price to save my most expensive investment."

"Nixon was amazing. I never have good experiences with handymen but he was able to fix my front door, weatherproof my doors, and fix my dehumidifier basement issue that have been huge issues before now. He’s reliable and does a great job. Highly recommend!"

Basement Waterproofing questions, answered by experts

Most people consider a French drain to be one of the most effective solutions for foundation leaks, but it’s not always a standalone solution. French drains will help keep water away from your foundation to reduce the risk of leaking and structural damage from soil expansion, but depending on your foundation type and location, you might need other systems or techniques—like soil gradation and gutter and leader installation—to resolve the underlying problem.

Living in a finished basement is acceptable, but only if the space has the proper points of egress and includes smoke and carbon monoxide (CO) detectors to ensure the safety of the occupants. A good way to ensure your finished basement is suitable for use as living space is to get the basement finishing project properly permitted.

As the first layer of water protection for your roof deck and the building materials below, underlayment is designed to prevent water damage, so it’s okay if it gets wet. However, you shouldn’t rely solely on underlayment for protection. If rain interrupts your roof project and you have all of the underlayment down, you’ll likely be fine, but you should install shingles over that layer as soon as possible, as long-term exposure can lead to water damage.

Foundation repair uses methods such as underpinning, slab jacking, or application of hydraulic piers. Each technique is chosen based on structural needs, soil conditions, and damage extent, ensuring a stable and secure foundation.

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.
