Local Expertise
Underpinning for Ajax Homes
Ajax homeowners looking to maximize their living space find underpinning to be a cost-effective solution compared to adding an addition. Many Ajax homes from the 1990s have basements with 6.5–7 foot ceilings that can be extended with underpinning. We bring honest, competitive Durham Region pricing to every Ajax underpinning project.
