Patio extension quote checklist

Use these checks when a patio add-on looks like a simple square-foot price.

Signal to checkWhat it meansNext step
Added areaThe quote clearly states the new strip, pad, flare, or expansion square footage.Recalculate the added area and compare the same footprint.
Existing edgeThe bid states saw cut, isolation joint, dowels, reinforcement, and how the new work meets the old surface.Ask for a written edge and joint detail before comparing finish prices.
Base and drainageExcavation, gravel depth, compaction, slope, soft spots, and runoff are included or explicitly excluded.Open the gravel base calculator and confirm the water path after widening.
Small-load deliveryThe supplier quote shows minimum yards, short-load, delivery, wait, access, and washout terms.Compare the delivery minimum and bags-vs-ready-mix break-even.
Finish and permitHOA, curb, slope, broom direction, color, sealer, and cleanup responsibility are clear.Keep local approval and finish-match assumptions beside the price.
