About Keystone Outdoor Solutions
Keystone Outdoor Solutions is a family-owned landscape contractor serving Lancaster and Harrisburg, Middletown, Columbia, and surrounding areas. Since 2002, our team of expert builders has designed and installed custom decks across South Central PA, offering licensed and insured services to ensure your safety and confidence throughout the build.
Our Services
Every deck is custom. Pick the material and style you want and we build it.
A natural wood deck brings warmth and character that synthetic boards cannot replicate. Keystone Outdoor Solutions builds cedar and pressure-treated wood decks cut and finished to match your home, your yard, and the way you plan to live on it for years ahead.
A PVC deck is the easiest deck you will ever own. Fully synthetic boards shrug off moisture, sun, and insects, so there is no staining or sealing to chase every spring. Our team installs PVC decks built to hold their color and finish for decades in Central PA weather.
No two backyards are the same, and your deck should not be a template either. Our designers shape every custom deck around your home, your sight lines, and how you actually plan to use the space, from quiet morning coffees to full weekend gatherings with the whole family.
A multi-level deck turns an awkward slope into your favorite room of the house. Our team builds staged levels with dedicated zones for dining, lounging, and grilling, tied together with built-in benches, planters, and wide stairs that feel natural underfoot.
We had Keystone Outdoor Solutions build a paver patio and sitting wall off our kitchen last spring, and it turned out exactly what we hoped for. The team showed up when they said they would, cleaned up every single day, and the finished space looks better than the 3D rendering.
After getting three quotes for a retaining wall, we went with Keystone Outdoor Solutions because they actually walked our slope and explained why the base needed to go deeper than the other guys quoted. One year in, zero settling. Worth every penny.
From the first phone call to the final walkthrough, this was the best contractor experience we have had as homeowners. No runaround, no subcontractors we had never met. Just one team that handled our driveway, stone veneer, and stood behind every piece of it.
Our township is a nightmare with outdoor kitchen permits. Keystone Outdoor Solutions pulled everything, submitted the drawings, and scheduled the inspection without us lifting a finger. The project passed the first time. That alone was worth hiring them.
We already had a paver patio and wanted a deck, fence, and fire feature added. Keystone Outdoor Solutions was the only contractor who could actually picture all of it as one connected space. The materials, the sight lines, and the finish all match. It looks like it was always there.
A better backyard starts with one phone call. Our Lancaster deck builders handle the design, the permits, and the build under one roof, so you spend less time managing the project and more time enjoying the finished space.

Areas We Serve
Based in Lancaster, PA, Keystone Outdoor Solutions designs and builds custom hardscaping and outdoor living spaces for homeowners across South Central Pennsylvania. From paver patios and retaining walls to outdoor kitchens and custom decks, our crew serves the greater Lancaster area and surrounding counties.
Lancaster, PA sits in the middle of South Central Pennsylvania, surrounded by rolling farmland, historic boroughs, and tight-knit neighborhoods where homeowners genuinely care how their yards look. Backyard upgrades have become one of the most popular investments across Lancaster County, with custom decks leading the way as families spend more time entertaining at home.
Central PA weather is not forgiving. Hot, humid summers swell and fade the wrong boards, and freeze-thaw winters punish any deck built on shallow footings or cheap fasteners. Keystone Outdoor Solutions has been building in these conditions since 2002, using the materials and installation methods that actually stand up to what Lancaster throws at them.
FAQ's
In Lancaster, PA, pressure-treated wood decks run roughly $30 to $50 per square foot. Composite runs $50 to $80. PVC runs $70 to $100. Multi-level, covered, or fully custom builds typically start at $100 per square foot.
A standard deck takes one to two weeks on site once we break ground. Larger builds with roofs, multiple levels, or custom railings run three to five weeks. Design and permitting happen before that window starts. If you’re looking for reliable mold removal services in Pittsburgh, contact Mold Men of Pittsburgh for expert assistance.
In most cases, yes. Attached decks and any deck over 30 inches off grade need a township permit. We handle the drawings, submissions, and inspections so you never deal with the township directly.
A properly installed composite deck lasts 25 to 50 years in Pennsylvania. Lifespan comes down to the board brand, the quality of the substructure, and whether the ledger and footings were flashed and set to frost depth.
For most Central PA homeowners, composite wins. It resists rot, holds color through freeze-thaw, and needs almost no upkeep. Wood is cheaper upfront and warmer in hand, but plan on sealing it every two to three years.
Yes. We design decks and paver patios as one connected outdoor space all the time. We can move a new deck down to your existing patio, tie in shared stairs, and match materials so the two surfaces read as one build.
Spring and early fall are ideal. The ground is workable, concrete cures cleanly, and stain sets properly. We build year-round, but winter frost can delay footings and mid-summer heat can rush composite installations.
At least 36 inches. That is the frost line across Lancaster County and most of Central PA. Footings set shallower than that will heave within a season or two once the first hard freeze-thaw cycle hits.
