What does interlock cost?
Interlock patios start from $25 per square foot and interlock walkways from $20 per square foot, for standard concrete pavers. Premium Techo-Bloc and Permacon products and curved layouts sit above that. Retaining walls and armour stone are quoted per job rather than per square foot, because height, drainage and the stone itself drive the cost far more than the area does. Either way the rate is a starting point, not a quote: tearing out an existing surface, steps and level changes, retaining along the edge and poor machine access all move it. We look at the site and give you one all-in number before anything starts.
How long does a patio or walkway take?
Most residential patios and walkways run two to four days on site, depending on size, access and how much digging the base needs. You get the schedule with the quote. If there is an old patio, deck or walkway in the way, we tear it out and haul it off on the same job, so you are not hiring a second company for the demolition.
Will it sink or heave over the winter?
That is what the base is for. Stone laid on thin or uncompacted fill moves the first time the ground freezes and thaws. We excavate to depth, put in clean granular, compact it in lifts rather than all at once, then screed the bedding layer level. It costs more in machine time up front and it is the whole difference two winters later.
Can you tear out the old patio first?
Yes, and it is normally cheaper to have us do both. The machine is already on site and the trailer is already there, so removing the old surface and hauling it away gets quoted into the same price.
What materials do you work with?
Concrete pavers and slabs, natural flagstone, armour stone, and segmental block wall systems. We will walk you through what suits the site and the budget, and you can pick the exact product at the supply yard before we order.
Do I need a permit?
Most residential patios and walkways do not. Retaining walls above roughly a metre often do, and the threshold and rules vary by municipality across Niagara. We flag it when we quote so you are not finding out afterwards.
When in the year can you build?
Roughly from once the frost is out of the ground in spring through to late fall. Spring and early summer book up first, so if you want a patio for the summer it is worth getting the quote in over the winter.
