"Situation resolved!!!! This started off as a little bit of water in the corner of the basement but escalated very quickly with the snow melt. Sean was here the same day I called to assess the situation and began work shortly after. They had to chop up the entire perimeter of the basement floor to install the french drains. This is definitely messy work and they never left a mess behind. All the guys were great and the work was well done and in a very timely manor. HUGE amount of stress has been lifted and thank you to Century Masonry and Waterproofing for making the process relatively painless."

"I had a previous company come in to waterproof my basement and they charged me more than Once and Done and did a horrendous job. They didn't do it correctly and more mold grew. Once and down came in, tore out the previous work and put in their system and my basement is completely dry even during the wettest months & completely mold-free. They gave excellent customer service and priced the job VERY reasonably. This is an honest company and do super work. I would give them 10 stars if I could."

"John & his crew did an excellent job repairing my foundation & also cleaned & painted using epoxy on my basement walls...no more musty smell! Without me asking, John did other small repairs unrelated to what I hired him for. John & his men did a very neat job in a timely fashion. I would highly recommend him."

Basement Waterproofing questions, answered by experts

To ensure your basement walls are waterproof, it's crucial to address any existing moisture issues before finishing. Inspect for signs of water seepage, such as dampness or discoloration, and repair any leaks or cracks. Install a vapor barrier to prevent moisture from penetrating the walls, and consider waterproofing paints or coatings.

Proper drainage systems, such as interior or exterior waterproofing, can also be beneficial.

In perfect conditions—meaning, no overexposure to the elements without roofing material on top of it—an ice and water shield can last for decades. In fact, many come with a limited lifetime warranty because they should last for a long time. If, however, the membrane is exposed to the elements during building or if there is a delay in installing the roofing material, it might only last up to 180 days if exposed to the elements. The key is to make it a layer of protection and then protect that layer by installing the roofing.

You should always hire a structural engineer or a professional and licensed foundation repair company for crawl space repair. These professionals will often be able to treat the symptoms of the issue as well as the underlying problem so that you don’t have ongoing damage. They’ll also often take preventative measures to stop the issue from recurring in the future.

Yes, you can technically make a crawl space liveable, but the only way to do so is by converting it into a basement. While some crawl spaces are big enough to walk through and store large items, they lack appropriate insulation and space to be liveable.

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.
