Concrete pool decks in Bethesda, Potomac and Rockville, Maryland.

01 / Local know-howWhy a pool deck in Montgomery County is its own build.

A pool deck lives a harder life than any other flatwork on the property. It’s wet most of the summer, splashed with pool chemistry, walked on barefoot, baked by afternoon sun, and then asked to survive a Maryland winter of freeze-thaw right next to a body of water. Get any one of four things wrong — traction, drainage, the joint at the coping, or the base — and the deck either becomes a slip hazard or cracks within a couple of seasons. We design around all four from the start.

What it means across our service area:

• Potomac (20854): the large Falls Road and Avenel properties where most of our pool work is — generous decks that tie the pool to a patio, an outdoor kitchen and the house. Bigger decks mean more attention to drainage and more expansion jointing. Avenel and similar HOAs review the design before work starts; we prep that submittal.
• Bethesda (20814 / 20816 / 20817): tighter Edgemoor and Bradley Hills lots where a pool deck has to work in a compact yard, often stepping between grades — we’ll pair the deck with a low seat or retaining wall to carve the flat pad the pool needs.
• Rockville (20850 / 20852) & Silver Spring: classic broom or textured decks around family in-ground pools, permitted through the City of Rockville or the county. Clean, cool-tone, low-maintenance.

Chevy Chase sits in the same envelope. Wherever the pool is, the deck is engineered for grip and drainage first — the good looks come standard on top of that.

02 / The build, in sectionThe four details that keep a pool deck sound.

The drawing below is the part of the deck you never see — and it’s where a deck is won or lost:

1. A slip-resistant, cool-tone finish.

A wet pool deck is exactly where you can’t afford a slick surface, so we finish decks with real texture — a broom drag, a light stamp, a knockdown or “cool-deck” spray, or exposed aggregate — never a steel-troweled shine. We steer you toward lighter colors, too, because dark concrete in Maryland’s July sun gets too hot for bare feet.

2. A slope that drains away from the pool.

The whole deck is pitched about a quarter inch per foot away from the water so rain, splash-out and hose-down all run off away from the pool rather than carrying dirt and lawn chemicals back in. Where the yard won’t let water escape, we build in channel or deck drains so the surface never ponds — and never turns into an ice sheet in winter.

3. A flexible expansion joint at the coping.

This is the detail that saves the deck. The slab is isolated from the pool coping with a flexible expansion joint so the deck and the pool structure can move independently through freeze-thaw. Bond a deck rigidly to the coping and the first hard winter cracks the deck or lifts the coping tile. We keep them separate on purpose.

4. Reinforced concrete on a compacted base.

Air-entrained, reinforced concrete on a compacted crushed-stone base, with proper control joints. Air entrainment builds microscopic bubbles into the mix that give freezing water somewhere to go — the Portland Cement Association has documented for decades that it’s the key to concrete surviving freeze-thaw. On a deck that gets soaked daily, it isn’t optional.

03 / FinishesPool deck surfaces we build across Bethesda, Potomac & Rockville.

Broom & textured concrete

The value pick: a brushed or lightly textured slab that’s grippy, cool in a light color, and easy to keep clean. Understated and durable — the right call for a family pool.

Cool-deck & knockdown overlays

A sprayed, textured cementitious topping that stays cooler underfoot and adds grip and color — excellent for resurfacing a sound but tired existing deck without tearing it out.

Exposed aggregate

Washed-back stone for a naturally high-traction, warm, pebbled surface that hides wear and pool chemistry beautifully. A longtime favorite around Potomac pools.

Stamped concrete

Stone and plank patterns pressed into the pour for a high-end look at a concrete price — sealed with a grit additive for traction. Coordinate it with a matching stamped patio, and mind the same resealing schedule.

Paver pool decks

Interlocking pavers that flex with freeze-thaw instead of cracking, with individually replaceable units — the same system as our paver driveways, sized and drained for poolside.

04 / PricingCost of a concrete pool deck in Bethesda, Potomac & Rockville (2026).

Pool decks price by the square foot, driven by the finish and by how much drainage and jointing the site needs. The honest 2026 band in our service area is $9 to $30 per square foot. Here’s the line-item sheet behind a typical textured deck — the same itemized proposal you get after the site walk.

Put to a real deck: a 700 sq ft deck around an in-ground pool runs roughly $6,500 — $11,000 in a textured finish, or $11,000 — $20,000 stamped. Resurfacing a sound existing deck with a cool-deck overlay costs a fraction of a tear-out — the same reseal-vs-replace math we lay out in our resurfacing & repair service. The cheap deck skips the isolation joint and the drainage to hit a low number, and it’s the one that cracks at the coping first.

05 / Permits & safetyWhat Montgomery County requires around a pool.

• Permits: the pool itself is permitted through Montgomery County DPS (or the City of Rockville inside city limits), and the deck is part of that scope. New impervious surface can also trigger stormwater review. Our guide to building a patio or deck around an existing pool covers permits and costs in detail.
• Barrier & safety: residential pools require a compliant barrier (fence and self-closing, self-latching gates) under the building code — the same layered protection the U.S. Consumer Product Safety Commission promotes to prevent child drownings. We coordinate the deck so the barrier and gates work with it.
• Drainage: the deck must move water away from the pool and off the surface — a code and a common-sense requirement we design in.
• HOA review: Avenel and similar communities review the design first; we prepare the submittal.
