Posted this here because I spent 3 months comparing quotes and I know other GTA homeowners go through the same process. We had a 400 sq ft rear patio in terrible shape — heaved slabs from the 2022 frost cycle, half the joints had washed out, and one section near the foundation had a negative slope draining toward the house. Got four quotes ranging from $7,800 to $19,200 for the same project. Went with [The Local Builders](https://thelocalbuilders.ca) after talking through the base prep specs with them. They were the only contractor who told me upfront that the clay sub-base under my yard would need an extra 4" of granular A compared to the standard spec, and priced it into the quote rather than hitting me with an add-on after excavation started. The actual process: - Full excavation to 14" (clay condition required the extra depth) - 4" clear stone drainage layer at the base - 10" Granular A in two compacted lifts - 1" bedding sand - Permacon pavers (chose the Roma series, 80mm thick) - Polymeric sand joints with sealer applied 30 days after install Total came in at $14,400 which was mid-range. Timeline was 4 working days for a crew of 3. Six months later — through the 2026 freeze-thaw — zero heave, joints still tight. The foundation drainage slope runs 2% away from the house, which I measured myself after install. Happy to answer questions on the quote comparison process if anyone is going through it.
