A stamped concrete patio is the most-requested upgrade we pour in Montgomery County — and the one homeowners are most often surprised by on price. Not because it’s expensive, but because two quotes for “the same” patio can differ by $4,000. Here’s exactly where that money goes in 2026.
In 2026, a stamped concrete patio in Potomac, Bethesda, and Rockville runs $16 to $28 per square foot, installed and sealed. For a typical 400 sq ft patio — a comfortable size for a dining table and a small seating area — that’s roughly $6,400 to $11,200 finished. Below, we break the number down the way it appears on our own line-item proposals, then show how it stacks up against pavers and a plain broom finish.
01 / The numbers, up frontWhat a stamped patio actually costs in 2026.
For a 400 sq ft stamped concrete patio with a single-color ashlar slate pattern, here’s how a mid-range job breaks down per square foot:
So a 400 sq ft patio lands at roughly $6,400 to $11,200. Add a second color (border + field), a band detail, or a more intricate pattern like herringbone brick and you’re at the top of that range. A bare-bones pour with a thin base and a single broadcast color can come in lower — and telegraph every crack the ground throws at it within a few winters.
02 / The biggest swingWhy two quotes differ by thousands.
The stamping line is where the spread lives. “Stamped concrete” can mean a single integral color with one pattern mat, or it can mean a hand-detailed, two-color, multi-pattern surface with a contrasting border. Both are “stamped.” They are not the same labor, and they are not the same price.
- One color, one pattern. The most common, and the value sweet spot — around $6–$7/sq ft for the decorative work.
- Two colors (base + antique release). Adds depth and realism. Roughly $8–$9/sq ft.
- Border + field, multiple patterns. A stone field with a soldier-course brick border reads custom — and runs $9–$10+/sq ft.
When you’re comparing quotes, the question to ask isn’t “how much per square foot” — it’s “how many colors, which patterns, and is there a border.” That single question explains most of the gap between two numbers.

03 / Stamped vs. pavers vs. broomWhat each surface costs in Maryland.
The three patio surfaces we build most in Montgomery County, priced head-to-head per square foot, installed:
Stamped concrete almost always wins on up-front price against pavers and flagstone, because it’s one monolithic pour instead of hundreds of hand-set units. Where pavers earn back the difference is repairs: a settled or stained paver lifts out and resets; a cracked stamped slab gets patched, and the patch rarely matches. If you want the full durability and resale comparison, we wrote a dedicated head-to-head on stamped concrete vs. pavers vs. flagstone in Maryland.
Clay soil is the hidden cost line.
Most of Potomac, Bethesda, and Rockville sits on expansive clay that swells and shrinks with the seasons. A stamped patio that skips proper base prep will crack right through that beautiful pattern — and on stamped concrete, a crack is permanent. Budget for the base; it’s the line item that protects every dollar above it.
04 / The costs most quotes hideFour lines to look for.
The patios that go over budget almost always do it on the same handful of items — the ones that aren’t glamorous enough to put in a sales pitch:
- Site access & protection. A backyard a wheelbarrow can’t reach means concrete by buggy or pump — real labor and a real line item.
- Grading & drainage. A patio has to shed water away from the house at the correct pitch. Re-grading a flat or sloped yard costs money up front and saves a flooded basement later.
- Tear-out of an old surface. Removing and hauling an existing patio or slab adds $2–$4/sq ft before the new one starts.
- The first sealer coat — and every one after. Stamped concrete must be sealed, and resealed. Confirm the first coat is in the quote.
05 / The cost nobody quotesResealing, every few years.
Stamped concrete’s color and sheen live in a topical sealer, and in Maryland’s freeze-thaw and road-salt climate that sealer wears. Plan to reseal every 2 to 3 years — roughly $200 to $500 for a 400 sq ft patio if you hire it out, less if you roll it yourself. Skip it and the color dulls, the surface gets porous, and freeze-thaw starts working on it. We laid out a realistic schedule in our guide to how often to reseal a stamped concrete patio in Maryland.
It’s a modest recurring cost, but it’s real — and it’s the honest tiebreaker between stamped concrete and pavers, which need no sealing at all. Factor it into a 10-year cost of ownership, not just the install number.
06 / Timeline & seasonWhat affects the schedule (and the price).
A 400 sq ft stamped patio is generally a 3- to 5-day job: a day for excavation and base, a day for forms and reinforcement, the pour-and-stamp day, then cure and seal. The pour day is the one that can’t be rushed — stamping has a tight window while the concrete is at the right firmness, which is exactly why crews charge for it.
Season matters more than most homeowners expect. We don’t stamp into a cold snap or a 95° July afternoon — both ruin the finish — so spring and fall book out first across the DMV. If you’re timing a project, our breakdown of the best time of year to pour concrete in the DMV is worth a read before you lock a start date.
Every patio quote we send is itemized.
Base depth, reinforcement, color count, pattern, sealer — it’s all on the page. If you ever see “stamped patio — lump sum” on a proposal (ours or anyone’s), ask for the breakdown before you sign. A patio is too permanent to buy blind.
07 / Frequently askedStamped patio cost questions, answered.
How much does a stamped concrete patio cost in Maryland?
In 2026, $16 to $28 per square foot installed for most residential jobs in Montgomery County. A 400 sq ft patio typically lands between $6,400 and $11,200 finished, depending on the pattern, number of colors, site access, and how much grading and base work the yard needs.
Is a stamped concrete patio cheaper than pavers?
Usually, yes. Stamped concrete runs $16–$28/sq ft installed versus $22–$38/sq ft for pavers in the Potomac and Bethesda area, because it’s one pour instead of hundreds of hand-set units. Pavers win on long-term repairs, though — a settled paver lifts and resets, while a cracked stamped slab can only be patched.
How much more does stamped concrete cost than a broom finish?
Stamping, color hardener, and release agent add roughly $6 to $10 per square foot over a standard broom-finished patio. On a 400 sq ft patio, that’s about $2,400 to $4,000 more for the decorative finish.
Do I need a permit for a patio in Montgomery County?
A grade-level patio that doesn’t add significant impervious area often doesn’t need a building permit, but stormwater rules kick in past certain impervious-surface thresholds, and a patio attached to a deck, wall, or structure may. Watershed-protected zones near the Potomac River are stricter. A licensed Maryland contractor confirms the requirement before pouring.
How long does a stamped concrete patio last in Maryland?
A properly based, reinforced, and regularly sealed stamped patio lasts 25 to 30+ years in Maryland. The two things that shorten that life are a skimped sub-base (cracking) and skipped resealing (surface wear and freeze-thaw damage).
08 / Final wordPay for the base. Budget for the seal.
A stamped concrete patio is the best-looking square foot you can buy for the money in Maryland — provided two line items are right: a base built for our clay, and a sealing schedule you’ll actually keep. Get those, and a $16–$28/sq ft patio outlasts the house’s next two owners. Skip them, and the cheap quote becomes the expensive one.
