Should You Consider Waterproofing When Buying or Renovating Your Home?

Waterproofing your home is an important part of protecting it from the damaging effects of water. It can help to protect its structural integrity and ensure a healthy living environment for your family.

Waterproofing helps to prevent moisture from entering the foundation, walls, floors, and other structures of your home. This can help to prevent mould growth and avoid costly repairs due to water damage.


Benefits of Waterproofing

Waterproofing your home comes with many benefits, including:


1) Reduced Risk of Flooding

Waterproofing can help to reduce the likelihood of flooding in your home due to heavy rain or snowfall. This will help to keep the structure and contents safe from water damage.


2) Increased Energy Efficiency

Waterproofing your home can result in better energy efficiency by preventing cold air from entering in the winter and hot air from entering in the summer.


3) Protection from Mould Growth

Waterproofing your home is important not only for preventing water damage but also for preventing the growth of mould and mildew, which can harm your health and weaken the structure of your home.


4) Increased Property Value

Waterproofing your home can also increase its property value, as it is seen as a major selling point for potential buyers.


What Part of the House Requires Waterproofing?

The most common areas of your home that require waterproofing are the basement, crawl spaces, and exterior walls.

  • Crawl Space Waterproofing: Waterproofing the crawl space is important even though it can be challenging to access and examine. Neglecting this area can result in it being more susceptible to water damage.
  • Exterior Wall Waterproofing: Properly sealing exterior walls can prevent rain and snow from getting into the house, helping to reduce the growth of mould and keep your home energy-efficient.

When considering waterproofing, there are a few important things to keep in mind:

1) Seek Professional Advice

To ensure effective waterproofing solutions for your home, it is crucial to consult with a certified waterproofing contractor. They can evaluate your situation and recommend the most suitable course of action.


2) Check Local Regulations

Before starting any waterproofing work, it is important to check for any local regulations or restrictions that may be in place. Doing so could help you save time and money in the future.


3) Research Materials

To ensure proper waterproofing of your home, it is recommended that you conduct research on the various types of waterproofing materials and select the most suitable one.
