You’re reading this right. Quote 2 is the classic underprepared-base scenario.

A few things stand out immediately:

**“Standard base”** is not a spec. It is a non-answer. In Brampton, a proper residential driveway base runs 10 to 12 inches of compacted Granular A stone, laid in 2-3 inch lifts with a plate compactor after each pass. If a contractor cannot tell you the base depth in inches and the material by name, they are not prepared to do the job properly.

**No polymeric sand** is a serious red flag. Regular sand washes out within a season or two. Polymeric sand locks the joints, resists ants, and keeps the field stable. On a driveway — where you have vehicle loads — this is not optional.

**The math:** Quote 2 at $9,800 for 480 sq ft is about $20 per square foot installed. Quality interlock work in the GTA right now runs $25 to $45 per square foot for a standard residential driveway. The gap between Quote 1 and Quote 2 is almost entirely base prep and joint material. That difference will show up as heaving and joint failure within 3 to 5 years.

**Quote 1 at $14,200 ($29.58/sq ft)** is a reasonable number for the scope described, assuming they actually deliver the base depth they are promising. Get that in writing — specifically the depth and material for the granular base, compaction method, and the polymeric sand brand.

**Quote 3** is reasonable for Brussels premium with a decorative border.
