How to Bid a Concrete Job: Pricing That Protects Your Margin

Concrete work punishes a sloppy bid faster than almost any other trade. Material prices swing, a slab pour has almost no room to fix a mistake after the fact, and a missed line item in the bid comes straight out of your profit margin. Here's how to bid a concrete job so the number you send actually holds up once the pour starts.

How do you quote concrete work?

A real concrete bid has four parts, priced separately:

• Scope of work. Slab, driveway, footing, decorative concrete — write down dimensions, thickness, and finish before pricing anything. "Pour a slab" isn't a scope; "20x20 slab, 4-inch, broom finish" is.
• Materials. Concrete by the yard at current supplier pricing (it moves — don't quote off last month's number), rebar or mesh, forms, and finishing materials.
• Labor. Crew size and hours for prep, forming, pour, and finishing — concrete finishing in particular takes skilled labor hours that shouldn't be underpriced.
• Overhead and profit margin. Equipment, insurance, and a real markup — not what's left over after materials and labor. Bid the margin in, don't hope it survives.

How much should a 20x20 concrete slab cost?

Pricing varies a lot by region, slab thickness, site prep needed, and finish — a plain broom-finish slab costs meaningfully less than decorative concrete with a stamped or stained finish. Rather than anchoring to a number you saw online, price your own market: your material cost per yard, your crew's real labor hours for that size and finish, plus overhead and margin. That's the number that protects you, not a generic average.

Win more concrete jobs by bidding faster

Contractors and general contractors sourcing subcontractors for concrete work usually move fast — the crew that gets back with a credible bid first often wins the job, even over a lower bid that arrives two days later. For jobs where the scope is visible from photos (slab area, existing surface, access to the site), you don't need to schedule a visit just to put a number together.

Fast Snap Pro lets a customer or general contractor send photos and a description through a link, and it comes back scoped and priced against your own concrete rates — material cost per yard, your labor hours, your margin — so you can respond to a bid request in minutes instead of losing the job to whoever showed up first.

Bidding concrete jobs as a sub vs. direct to the customer

How you price a concrete project can shift depending on who you're bidding to. A general contractor sourcing subcontractors for a bigger build usually wants a fast, itemized bid they can slot straight into their own numbers — pricing per yard, labor, and a clear scope of work. Bidding concrete jobs direct to a homeowner is more about the pitch: showing options (plain slab vs. decorative concrete, different finishes) alongside the price. Either way, the trade fundamentals — material cost, labor, overhead, margin — stay the same; only the presentation changes.

Price it right the first time

Concrete doesn't give you a second pour to fix an underpriced bid. Build your line items — material, labor, overhead, margin — once, and use them on every concrete job so your bids stay fast and your margin stays intact.
