How to Read a Hardscape Bid Before You Sign

Most hardscape bids look more complete than they actually are. A single line like "paver patio install — $18,400" can hide a dozen decisions that materially affect both the price and how the finished project holds up. Here's what a bid should actually spell out, trade by trade.

Base prep, not just the finish material

Whatever's under the surface — compacted base gravel for pavers, sub-base and reinforcement for concrete — matters more to long-term durability than the material on top. A bid that jumps straight from "excavation" to "paver installation" without naming a base depth or compaction standard is skipping the part of the job that actually prevents sinking, shifting, and cracking.

Ask for the base material and depth in writing, not just "properly prepared base."

Material grade and specific products

"Pavers" or "concrete" isn't a spec — it's a category. Material grade, thickness, and finish all swing price significantly within the same category, and a vague bid line gives a contractor room to substitute a cheaper product than what you were picturing when you agreed to a number. Ask for the specific product line, color, and thickness in the contract, not just the category.

Allowances should be scoped, not just priced

An "allowance" (a placeholder dollar amount for a scope that isn't fully designed yet — electrical, plumbing tie-ins, fixture selections) is normal on a bid. What's not normal is an allowance with no detail behind it. A $2,200 electrical allowance should say how many fixtures, what wattage, and roughly how much trenching — not just a number. Vague allowances are one of the most common places change orders show up after you've already signed.

Permits and engineering — don't assume they're included

If your project needs a permit (common for structures, retaining walls above a certain height, some electrical/gas work) or a stamped engineering review, confirm explicitly whether that's included in the bid price or billed separately. This is a frequent point of disagreement after the fact, and it's cheap to clarify up front.

Drainage is easy to skip and expensive to fix later

Pool decks, retaining walls, and patios all need a plan for where water goes — slope, drains, weep holes, backfill material. It's rarely called out explicitly in a one-page bid, and it's one of the most consequential omissions, since drainage problems usually don't show up until well after the check has cleared.

What to do with all of this

None of this means a bid is dishonest — most contractors aren't trying to hide anything, and plenty of solid bids are still written informally. But a bid that doesn't answer these questions puts the burden on you to catch the gaps, at a point in the process (before signing) where you have the most leverage to ask.

If you'd rather have someone who builds this kind of work read your specific bid and tell you what's missing or overpriced, that's exactly what Bid Review is for — a flat-fee, personally-written second opinion before you sign anything.
