Kitchener is the largest of the Tri-Cities, and a lot of its interlock is now 15 to 30 years old: driveways and front walks laid when neighbourhoods like Doon, Pioneer Park, Forest Heights and Laurentian Hills were built, plus newer patios in Huron Park and Williamsburg. KWC Interlock & Polymeric Sand connects Kitchener homeowners and property managers with vetted local interlock pros — no national call centres, no middlemen, just someone who actually works in your area.
Most interlock that looks finished isn't. Weeds in the joints, pavers that have sunk where the car tires sit, a walkway that rocks underfoot, a green film on the shaded side of the house: those are joint and base problems, not a reason to tear the whole thing out. In most cases the stone itself is fine.
The usual fix is three steps. Clean the surface and blow out the old joint sand and weeds. Lift and re-level the sections that have sunk, re-compacting the base underneath. Then sweep in fresh polymeric sand and activate it so it locks the pavers and keeps weeds and ants out. Done properly, it costs a fraction of new interlock and the surface looks close to new.
If large areas have heaved after a few winters, pavers are cracked across the surface, or water pools against the foundation because the original slope was wrong, re-levelling won't hold. A crew will tell you that on the quote rather than sell you a resand that fails by next spring.
See polymeric sand resanding, paver re-levelling and interlock cleaning & sealing for what each job includes. Work runs April to October; quotes are taken year-round.

Resanding in Kitchener typically runs $2–$4 per sq ft, or about $600–$2,000 for a 300–500 sq ft patio. Driveways are quoted per sq ft after measurement, and heavy weed or debris removal may add $100–$300.
