Concrete pool decks in Bethesda, Potomac and Rockville, Maryland.
A pool deck has to do three things at once: look like part of the house, stay cool and grippy under bare wet feet, and survive chlorine and a Maryland winter without cracking around the coping. We build decks that do all three — textured for traction, sloped to drain away from the water, isolated from the pool with a flexible joint, and sealed against the chemistry. New builds, replacements, and resurfacing a tired deck you already have.

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.
A salt-chlorinated pool is still salt on your concrete.
Salt-water pools are easier on your eyes, not on your deck — the generator makes chlorine from dissolved salt, and that salty splash-out attacks concrete the same way road salt does. On a salt-water pool we treat sealing as mandatory and reapply on schedule. It’s the same chloride problem behind our guide to how often to seal a driveway — the deck just gets it every single day of the summer.
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.
$12,000 — $40,000
Generous decks on Falls Road and Avenel properties tying pool, patio and outdoor kitchen together — stamped or exposed aggregate.
$8,000 — $22,000
Compact Edgemoor and Bradley Hills yards, often paired with a low seat wall to level the pad the pool sits on.
$6,000 — $16,000
Broom and textured decks around family in-ground pools — cool-tone, low-maintenance, City of Rockville permitted.
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.
- 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.

Most of our pool decks are part of a bigger backyard — one crew grading, decking, and building the kitchen and fire pit on one warranty.
06 / FAQWhat pool owners ask before they sign.
How much does a concrete pool deck cost in 2026?
About $9 to $16 per square foot for broom or textured concrete, $12 to $20 for exposed aggregate, $16 to $28 for stamped, and $18 to $30 for pavers. A 700-square-foot deck is roughly $6,500 to $11,000 textured or $11,000 to $20,000 stamped. Resurfacing a sound existing deck costs far less than replacement. Every Kempf proposal itemizes base, slab, joints and drainage.
What is the best non-slip pool deck finish?
Any real texture — broom, light stamp, knockdown / cool-deck spray, or exposed aggregate. We never leave a pool deck steel-troweled smooth, because it’s dangerous the moment it’s wet. Lighter colors also stay cooler underfoot in Maryland summer sun.
Why do pool decks crack around the coping?
Usually because the deck was poured tight to the coping with no isolation joint, so freeze-thaw movement had nowhere to go and cracked the slab or lifted the coping. A flexible expansion joint between deck and coping, plus a compacted base and proper control joints, prevents it. That joint is one of the first things we check on a deck we’re asked to repair.
Can you resurface my existing pool deck instead of replacing it?
If the slab underneath is structurally sound — no major settlement or deep cracking — yes. A cool-deck or knockdown overlay renews the surface, adds grip and color, and costs a fraction of a tear-out. If the base has failed, resurfacing only buys a little time and replacement is the honest answer. We’ll tell you which you’re looking at.
Is a salt-water pool harder on a concrete deck?
Yes. A salt-chlorine generator means salty splash-out, and that chloride attacks concrete like road salt does. On a salt-water pool we treat sealing as mandatory and keep it on a reapplication schedule so the surface stays protected.
Do I need a permit for a pool deck in Montgomery County?
The pool is permitted through the county (or City of Rockville), and the deck is part of that scope; new hard surface can also trigger stormwater review. Pools also require a compliant safety barrier with self-closing, self-latching gates. We coordinate the deck with the permit and the barrier.
