"Called company on Monday and got an appointment for an inspection on Wednesday. That following Monday, the technician arrived and went through each step is sealing off the concrete foundation to the water leak. The fix worked well and was put to the test with the recent record rains. Not one drop of water came into the basement."

"We had our basement waterproofed last year and were very happy. This year's project was adding two support beams. Again, we were very happy with the quality of the work and the people we dealt with. Both Gunnar and his team and Perfecto were skilled, efficient, and very professional. Highly recommend."

"My husband and I had a wonderful experience with The Real Seal in July 2024. They fixed a bowing foundation and waterproofed the basement for future finishing. Their team was prompt, respectful, organized and thoroughly educated us on the drainage tile system, installation process and prevention. Thank you, Real Seal for being the flawless first step to our dream basement/family space!"

Basement Waterproofing FAQs, answered by experts

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.

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. 

Typically, waterproofing a basement should last up to 10 years. However, it’s worth noting that with proper maintenance and depending on the waterproofing method and installation quality, you can probably squeeze another decade out of it.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. The chances of mold developing depend on several factors, including the severity of the damage and how quickly the area is cleaned and dried. To prevent mold, you must act quickly—ideally within the first 24 hours. Clean up all water and thoroughly dry the affected area. If the damage is extensive, you were unable to address it immediately, or you suspect mold has already started to grow, it is best to assume it is present and hire a professional mold inspector or removal expert to assess the situation.

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.
