Cost Guide: why two quotes for the same yard job differ
Two quotes for the same patio, wall or lawn job can differ by a wide margin, and the gap usually comes from things the two bids do not show side by side. This guide explains what moves a price, in the order I would weigh them, and what to ask before you sign. Sunday Backyard is an independent guide, and this page names no companies.
This guide does not give you a price list. The one sourced figure on this site is a national average for bluestone, and it is a baseline for testing a bid, not a Massachusetts price. Where I have no sourced figure, I say so rather than fill the gap.
Start with the job, not the number
A quote is a summary of a job, so when two summaries differ, the first question is whether they describe the same job. Compare the area in square feet, the base under it, the drainage plan, the material and how it reaches the site. If one quote leaves those lines out, a lower total may simply be covering less. The order of the work and the cash side of it live on the planning and budgeting pages, so this page stays with why a number moves.
Five things that move a price, in the order I weigh them
Access comes first for me. The bluestone figure assumes easily accessible conditions, so a yard a truck cannot reach, or where every load is carried by hand, starts above that baseline. Base depth comes second. For a paver patio or walk on well-drained soil, the Concrete Masonry and Hardscapes Association’s construction guide sets a minimum compacted base of 4 inches, and says bases must be thicker in cold climates where the soil stays wet or weak. Drainage is third, because where water stands decides whether that base holds. Material is fourth: the surface you choose changes both the labour and the materials, and the only price I can source is the bluestone one above. Size is last, because a larger area multiplies every line above it.
Questions to put to anyone before you sign
Ask how the contract is written. For home improvement work on an owner-occupied building of one to four units, Massachusetts General Laws chapter 142A says a contract over $1,000 must state the contractor’s registration number, the start and substantial-completion dates, and the owner’s three-day cancellation rights. The advance deposit is capped at the greater of one third of the contract price or the cost of special-order materials. Whether a landscaping or hardscape job falls under that law is not settled by the sources I checked, so ask the contractor how they handle the contract and read the statute yourself.
Ask who is calling Dig Safe before anyone digs. Massachusetts requires notice at least 72 hours ahead, not counting Saturdays, Sundays and legal holidays, and no more than 30 days before the excavation. A patio base, a wall footing and a tree hole all count as digging. A start date that ignores that notice period is a warning sign, and so is a quote that will not put its base depth in writing.
Comparing bluestone, brick and paver surfaces
Surfaces are easier to compare on what you have to check than on a single price. Bluestone is the surface behind the one sourced figure on this page, so it is the only one I can put a number beside. For brick and paver patios I do not have a sourced Massachusetts price, so I do not rank them by cost here, and I will not guess at one.
Upkeep is the other half of the comparison, and it is the half I cannot source either. Ask each bidder which joint material they recommend, what they expect to need after the first winter, and how they would repair one section without lifting the rest. Treat any ranking you read, this one included, as a claim to test against those answers.
