"The technician that did the service, let me know specifically one thing that turned not to be possible. I would never known, because the issue was below the ground. He also gave me post sales advice to recommend to my A/C who would be installing a unit near the repair."

Customers say: True professional

"Marlon Tuckpointing did a professional and seamless job on my chimney. I had missing mortar, discoloration, and a cracked and worn down chimney crown. Marlon came out right away and performed an assessment, made everything clear (including the price), and stayed in contact with me during the entire process. What impresses me most is their accuracy in workmanship, including the type/color match of mortar as well as the waterproofing work that protects my home from damage. When homes are 60+ years old, it is time to start thinking about the mortar and brick that holds your home together. While durable, over time, sacrificial mortar degrades and it's time to call in a professional to maintain the look and stability of your biggest asset. I am confident that you can trust Marlon Tuckpointing to do the job and am happy to recommend them."

Basement Waterproofing FAQs, answered by experts

While water in your basement is unlikely to make you sick unless it’s coming from a sewage backup, mold is likely to start to grow in wet areas within 24 hours, and mold can make you sick. According to the Centers for Disease Control and Prevention (CDC), inhaling mold spores can cause allergy symptoms, including runny nose, itchy eyes, difficulty breathing, wheezing, and itchy skin. Individuals with pre-existing respiratory issues like asthma and immunocompromised individuals are at an elevated risk of symptoms when inhaling mold spores.

If a crawl space isn’t vented, there can be moisture buildup, which can lead to mold damage, easily destroying the foundation of your home. A closed-off crawl space can trap heat, which can be useful in the winter, but can also trap dangerous gases and prevent clean air from entering the home through the floorboards.

Anything having to do with the structure of your home, such as raising the ceiling, is usually the most expensive part of finishing a basement. Another project component that could be a surprisingly high expense is adding an exterior entrance. 

The cost of a walkout basement can be anywhere from $5,000 to $35,000.

Rigid foam board insulation is one of the safest insulation materials for basement walls. The panels offer a moisture barrier to prevent mold and mildew build-up. At the same time, this material is also fire-resistant, so you don’t have to worry as much about a fire breaking out as you would with spray foam insulation. 

Many prevention methods can be used individually or in combination to waterproof your basement. Some of the most common waterproofing methods include:

  • Using dehumidifiers 

  • Silicate concrete sealers

  • Vapor barriers 

  • Baseboard channels 

  • Drain tile systems

  • Waterproofing paint

  • Drainage systems

  • Epoxy injection

  • Interior French drains

  • Exterior excavation and waterproofing

  • Cement waterproofing

  • Weep tiles

  • Liquid membrane

  • Sheet membrane 

  • Yard grading

  • Gutters and downspouts
