What’s the difference between interior & exterior waterproofing?

Interior and exterior waterproofing are two methods used by homeowners to prevent water infiltration into their homes. Here are the main distinctions between the two:


Interior waterproofing can be performed at any time, regardless of weather conditions. However, exterior waterproofing services are weather-dependent and may be more difficult to provide at certain times of the year.


Interior waterproofing work typically include the installation of a drainage system, such as a sump pump, to remove water from the home. Exterior waterproofing, on the other hand, is done to keep water from entering the home's foundation walls.


Interior waterproofing is usually less expensive than exterior waterproofing services. This is because interior waterproofing services require less excavation and are generally easier to install.


While both interior and exterior waterproofing services can prevent water infiltration, exterior waterproofing is generally thought to be more effective in the long run. This is because it addresses the underlying cause of the issue by preventing water from entering the foundation walls in the first place.


Interior waterproofing is done inside the house, whereas exterior waterproofing is done outside the house.
