"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."

"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

In most cases, yes, because the large majority of basements leak or will have moisture issues at some point, and waterproofing methods can mitigate that risk or eliminate it entirely. Plus, water and moisture issues can be quite problematic, as they can lead to mold growth, rotting of building materials, structural damage, poor indoor air quality, increased electric bills, and other problems.

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.

Flooded basement cleanup can take anywhere from a few days to several weeks, depending on the extent of water damage, the type of water involved, and the need for repairs or mold remediation. Severe cases with structural damage or extensive mold may require longer timelines. Quick action and professional help can speed up the process and reduce overall damage.

Proper drainage is the only way to ensure that your crawl space stays dry. Depending on your property and the extent of your issue, you might need to consider a gutter system, a French drain, or sump pumps to avoid and handle water and moisture under your home. Dehumidifiers can also help to prevent moisture from accumulating if you have a high-humidity environment.

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.
