Paver Patio & Hardscape Installation in the Greater Seattle Area
All Pro Landscaping & Construction Services LLC builds interlocking paver patios, walkways, steps, and courtyards across King & Snohomish County — on bases engineered for the soil under them, because that’s where patio performance is decided.
✓ Excavated & compacted base systems ✓ Drainage designed in, not added later ✓ Residential & commercial hardscape
The performance of a paver patio is determined by what’s beneath the surface. Properly excavated subgrade, compacted base layers, and drainage integration are why a well-built paver system in Seattle-area glacial soils performs for 25–30+ years — and why pavers typically outperform poured concrete here, where ground movement cracks slabs but only asks pavers to flex.
Paver Hardscape We Build
Paver Patios & Outdoor Living Areas
Entertaining spaces, dining areas, and fire-pit surrounds on fully prepared bases — laid out for how you’ll actually use the space, with drainage routed away from the house.
Walkways & Front Entries
Paths and entry hardscape that stay level and safe through wet winters — with edge restraint and base compaction that keep lines straight for decades.
Steps, Landings & Terraces
Elevation transitions coordinated with grading and retaining walls — a constant requirement on sloped Seattle-area lots, and a scope most patio-only installers can’t take on.
Raised Patios & Slope Mitigation
Retaining wall and paver systems designed together to create level, usable outdoor space on sloped properties — engineered and, where required, permitted as one system.
Courtyards & Multi-Element Spaces
Larger outdoor rooms combining paver surfaces, seat walls, planting areas, lighting conduit, and drainage as one coordinated construction scope.
Permeable Paver Systems
Where stormwater management matters, permeable paver systems let rain infiltrate through the surface into engineered base layers — an option worth evaluating on many Seattle-area sites.
Pavers vs. Poured Concrete — the Honest Comparison
In Seattle-area soils, pavers usually win on long-term performance. Here’s the reasoning, not just the claim:
- Ground movement: our glacial soils shift with moisture cycles. A concrete slab is monolithic — movement means cracks. A paver system is thousands of small units with flexible joints — movement is absorbed.
- Repairability: a settled paver section can be lifted, the base corrected, and the same pavers relaid — invisible repair. A cracked slab is patched (visible) or replaced (expensive).
- Drainage: paver joints and base layers move water; permeable systems do it by design. Slabs shed water to their edges, concentrating it where you often don’t want it.
- Where concrete wins: lowest upfront cost for simple, flat, low-movement sites. We’ll tell you when that’s genuinely your situation.

What’s Under a Patio That Lasts 30 Years
Every paver project we build follows the same base discipline — the part you never see and always feel:
- Excavation to design depth — Subgrade dug to the depth the soil profile and use case require — a driveway base is not a patio base.
- Subgrade evaluation & correction — Soft spots, organics, and water paths corrected before base material goes in — this is where future settlement is prevented.
- Compacted base in lifts — Angular base material placed and mechanically compacted in layers, not dumped and topped.
- Drainage integration — Grading, edge drainage, or subsurface drainage as the site requires — water always has somewhere to go that isn’t under your patio or against your foundation.
- Bedding, laying, edge restraint & joints — Screeded bedding layer, pattern-true laying, secured edges, and joint sand compacted in — the finish work that keeps everything locked.
Permits — the Short Version for Patios
At-grade paver patios generally don’t require a permit. Raised patios can: Seattle exempts platforms and walks under 18 inches above grade; Bellevue and Snohomish County exempt up to 30 inches. And a raised patio built on a retaining wall system follows retaining wall permit rules — over 4 feet from the bottom of the footing, or any height with a surcharge, means permits and engineering. We confirm your city’s requirements during planning.
What Determines Paver Patio Cost
- Square footage and layout complexity — curves, patterns, and multiple levels add labor
- Material selection — concrete pavers, natural stone, and permeable systems price differently
- Excavation depth and base requirements for your soil
- Drainage integration and grading scope
- Site access — machine access vs. hand-carry changes the labor picture
- Related structures: seat walls, steps, retaining walls, lighting conduit
Paver Patio Questions, Answered Straight
Are pavers better than poured concrete here?
Usually, yes. Pavers absorb the ground movement of our glacial soils, repair invisibly, and integrate drainage. Concrete wins on upfront cost for simple flat sites — and we’ll say so when that’s your situation.
Do I need a permit for a patio?
At grade, generally no. Raised patios: Seattle’s exemption stops at 18 inches above grade, Bellevue and Snohomish County at 30 inches — and patios on retaining walls follow wall permit rules.
How long will it last?
25–30+ years on a properly prepared base with drainage — base and drainage decide longevity, not the surface material.
Why do patios sink?
Base failure, almost always. Insufficient excavation, uncompacted base, or water in the base layers. Prevention happens before the first paver is laid.
When’s the best time to install?
Nearly year-round in Seattle’s climate. Extended heavy rain can affect base-work scheduling, but the finished system performs the same regardless of season.
What will it cost?
It depends on size, materials, base depth, drainage, and access — we price from a site evaluation and give you clear scope and cost expectations at consultation.
