About Keystone Outdoor Solutions
Keystone Outdoor Solutions is a locally-owned hardscape company rooted in Lancaster County. Over two decades in business, our teams have laid pavers, graded sidewalks, and poured stamped concrete across Lancaster, Reading, Phoenixville, Malvern, and every corner of South Central PA, all fully licensed and insured so you can hand off the project with full confidence.
Our Services
Every project is custom. Pick the material and layout you want and we build it.
A paver patio is the most versatile surface in the hardscape world. Our team hand-sets Unilock and Techo-Bloc pavers over a full-depth compacted gravel base, locking in the pattern you love so your patio stays flat and tight through every Pennsylvania freeze-thaw ahead.
Stamped concrete gives you the look of brick, slate, or natural stone in one seamless pour. We form, color, and seal every stamped patio on site, locking in the pattern depth and color tone so the finish holds through Central PA sun and winter de-icing alike.
Natural flagstone brings character no poured surface can match. Each stone is hand-set over a proper base with polymeric joints, shaping a patio that reads as though it has always belonged to the landscape around your home.
A clean walkway changes how a property feels before anyone walks through the door. Keystone Outdoor Solutions installed paver walkways and poured sidewalks graded for real drainage, pitched away from the foundation, and edged to hold their line long-term.
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 patio contractors 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.
Our Process
Clear stages, clear communication, clear timelines. Here is how a Keystone patio comes together from first conversation to finished surface.
01
We meet you at your property, measure the space, talk through how you want to use it, and map out a patio approach that fits your yard and your budget.
02
Our designers build a full 3D layout of your finished patio, so you can see the materials, pattern, and flow before we order a single pallet.
03
Our in-house crew excavates, compacts the base, and sets the surface piece by piece, keeping you updated every day until the patio is finished.
04
We walk the finished patio with you, clean the site top to bottom, and hand it over ready for grilling, entertaining, and decades of use.

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 is the heart of South Central Pennsylvania, a region known for its Amish farmland, historic downtown, and neighborhoods full of homeowners who take pride in every corner of their property. Outdoor patios have become one of the most requested upgrades in the area, giving families more room to gather, cook, and unwind without leaving home.
The climate here demands real build quality. Humid summers, heavy spring storms, and deep winter freezes expose any patio set on a shortcut base or cheap materials. Keystone Outdoor Solutions has been hardscaping through every Lancaster season for more than twenty years, using the base prep, drainage, and installation standards that actually survive Central PA weather.
FAQ's
In Lancaster, PA, standard concrete paver patios run roughly $18 to $30 per square foot. Premium Unilock or Techo-Bloc paver patios run $25 to $40. Stamped concrete runs $15 to $25. Raised patios and fully custom builds typically start at $40 per square foot.
A standard paver patio takes one to two weeks on site once we break ground. Larger projects with walls, fire features, or integrated lighting run three to four weeks. Design and permitting happen before that on-site window begins.
At-grade patios usually do not require a permit in Lancaster County. Raised patios, covered patios, and patios tied into retaining walls or roofs typically do. We confirm the requirement with your township and handle the paperwork for you.
A properly installed paver patio lasts 25 to 30 years or more in Pennsylvania. Lifespan comes down to base depth, drainage design, and polymeric sand joints. Shortcut installs usually start failing inside five to ten years once freeze-thaw sets in.
For most Central PA homeowners, pavers win. Pavers flex with freeze-thaw instead of cracking, single units can be replaced without tearing out the whole surface, and drainage is easier to control. Stamped concrete is cheaper upfront but harder to repair cleanly.
Yes. We design patios, walkways, and decks as one connected outdoor space all the time. A new patio can step down from your deck, tie into shared stairs, and match materials so the whole backyard reads as one finished build.
Spring and early fall are ideal. The ground is workable, the base compacts cleanly, and polymeric sand cures properly. We install year-round, but winter frost can delay excavation and mid-summer heat can shorten sand cure times.
Yes. We installed paver walkways, flagstone walkways, and poured concrete sidewalks across Lancaster County. Every walkway is graded for drainage, pitched away from the foundation, and finished with edging that holds its shape for the long haul.
At least six inches of compacted gravel over geotextile fabric, with an extra two to four inches on clay-heavy lots. That base depth is what keeps a patio level through Lancaster County freeze-thaw. Shortcut bases are the number one reason patios fail early.
