"I am 64 years old and have never done an online recommendation previously. I am in this instance due to their superior performance on my basement waterproofing and wall anchor project. Everyone affiliated with the company personified competence, conscientiousness and customer service. Have never had a better customer experience-could not recommend them any more highly."

"I would strongly recommend Kris Weaver and Baker's Waterproofing. Kris is extremely knowledgable about basement waterproofing, there's that. But he also did an excellent job of aligning scope and our budget. Baker's Waterproofing was highly recommended to us from friend and Kris exceeded all our expectations. He appears to be a top notch human being and we hired Baker's immediately. We are looking forward to getting started on the work and resolving our basement waterproofing issues."

"Highlander exceeded my expectations! Mr. Kevin Adams (Senior Inspector), did a thorough assessment of my basement and garage needs, clearly answered all my questions and proposed an easy to understand solution in writing. Mr. Cameron Shoemaker (Customer Care) made me feel like I was his most important customer ever. He kept me informed throughout the entire project and gladly worked with me when I had to postpone the start date of my project due to personal reasons. Wesley (Foreman) and his crew showed up on time and worked tirelessly to get the job done right and on time. When I brought up a couple of concerns at the end of the project, they quickly and without hesitation did what needed to be done to keep me satisfied. Great company and people who are 100% customer oriented!"

"I was having a hard time getting financing from the big box lenders but Mark was able to find me one and at short notice. When it looked like the deal would fall through because of title issues from the seller, Mark offered his guidance and expertise and was right there throughout the whole process. The whole 5 months! No call was to early, late or frequent. Mark was always accessible and immediately responsive. A man of his word. This property virgin and veteran is now living the American dream thanks to Mark Principi and the Central Lending staff. I would definitely recommend."

Basement Waterproofing questions, answered by experts

Make sure you're calling in the right expert to help repair and/or clean your crawl space. A serious issue may require multiple experts that include a local mold remediation pro, an HVAC pro, a foundation pro, and a plumber. You should also consider using a nearby junk removal service to avoid handling debris that could be covered in mold, fungi, rot, or asbestos.

Topical sealers adhere to the surface of concrete to create a protective layer. In many cases, this is all you need for concrete that sees light to moderate traffic, such as your basement. Penetrating sealers, on the other hand, bond with the free lime in the top layer of concrete to form calcium silicate, which prevents liquid from passing through. This type of sealer protects the surface from water, oil, and gasoline spills.

Unfortunately, mold can grow pretty much anywhere, on any kind of surface. However, you’re most likely to see it in damp areas like basements or bathrooms, as well as anywhere there has been a water leak. Consult a local mold specialist to determine if certain areas of your home are prone to mold based on climate and other factors.

The purpose of crawl space encapsulation is to prevent mold by blocking moisture and reducing humidity. If the vapor barrier is properly installed, it significantly reduces the chance of mold developing within the crawl space. However, mold can sometimes grow behind the encapsulation material, but it will be sealed away from the main area. Additionally, moisture can still condense inside the encapsulated space, so if you notice excess humidity, installing a dehumidifier is recommended to prevent mold and mildew growth.

Yes, you can finish a basement that leaks, as long as you address the leak first. Before finishing a basement, you’ll need to repair any cracks in the walls and waterproof the basement to prevent future leaks. It’s much harder to clean up a water leak from a finished basement than an unfinished one, so preemptively addressing any leaking areas prevents expensive repairs in the future.
