Your trusted underpinning experts
As a homeowner in Toronto, you know that lowering your basement floor will make additional living space and give you freedom from claustrophobia. The process of digging deeper beneath the footings of your home is referred to as underpinning. The next step involved is digging the floors deeper without undermining the support of your basement’s foundation walls. Thereby providing your low ceiling and awkward-looking basement a new life. It allows you to expand into a more livable space.

After getting a few quotes, we decided on Quality Age Build because of a trusted friend’s recommendation. I was impressed by the professionalism throughout the process. The quotation process was thorough and went through the waterproofing process in detail. The job was done in a timely matter and the job was fully completed without any loose ends. I will definitely be contacting them in the future for further services. Thank you

Underpinning is very helpful as a remedy to any damage that may be caused to your property’s foundation or structure. It addresses the following issues:
- One of the major faults is due to subsidence that happens due to mining or pumping activities. Underpinning is your solution when you want to strengthen your building’s structure and provide it with much-needed additional support in case of loss of its original strength.
- In a case when your home’s foundation, at the time of pouring, was not reinforced with rebars, it could be prone to side effects posed by the weight of your home. It could easily lead to movement or settling. Our underpinning services in Toronto can prevent the risk of occurrence of any of these issues.
Underpinning requires a complete survey of the condition of the foundation of your home. Once the preliminary study is concluded, the next step is an expert recommendation that will help restore your home’s lifespan. Upon receipt of planning permissions, work can be executed to bolster the structural integrity of the house.
