About Keystone Outdoor Solutions
Keystone Outdoor Solutions is a locally-owned masonry and outdoor living company serving Lancaster, PA since 2002. Our coating team works across Lancaster County on stucco exteriors, block and poured concrete basements, and brick, stone, and CMU walls of every age. We match the coating system to the wall, the moisture conditions, and the exposure, with no subcontractors and no guesswork.
Our Services
Keystone Outdoor Solutions offers a full range of stucco and protective coating services in Lancaster, PA. Every project starts with a surface and moisture assessment so we understand your walls before a single coat goes on.
New stucco done right is a system, not a finish. Our crew installs the full three-coat stucco system over properly fastened metal lath, with a weather-resistive barrier behind it and weep screeds and control joints placed where the wall needs them. Each scratch, brown, and finish coat is given its correct cure time, because rushing stucco is how cracks start. We install traditional cement stucco on homes, additions, garages, and garden structures across Lancaster County, in the texture and color that suits your property.
Hairline cracks, impact damage, bulging patches, and stained or hollow-sounding stucco are all common on Lancaster homes. Our stucco repair service starts with finding out why the stucco failed, not just covering the symptom. We rout and fill cracks, cut out and rebuild damaged sections with matching texture, and blend the repair so it disappears into the existing wall. Small repairs handled early cost a fraction of what spreading moisture damage costs later.
South Central Pennsylvania is well known for stucco-clad homes from the 1990s and 2000s that trapped water behind the cladding due to missing flashing and drainage details. We inspect for moisture intrusion, open up suspect areas, and correct the underlying flashing and drainage problems before any new stucco goes on. If your home needs full remediation rather than a patch, we tell you honestly and show you why. That distinction matters enormously for Lancaster homeowners, especially before a sale.
Lancaster basements in block, poured concrete, and old limestone all benefit from a properly applied parge coat and masonry coating. We repair spalling and open joints, apply a fresh parge coat to give the wall a clean, uniform surface, and finish with breathable masonry coatings that resist dampness and dusting. The result is a brighter, cleaner basement wall that sheds surface moisture instead of absorbing it.
Elastomeric coatings are far thicker and more flexible than paint. Applied over sound stucco, concrete, or masonry, they bridge hairline cracks and form a durable, waterproof skin that moves with the wall through Pennsylvania’s freeze-thaw swings. We prep the surface properly, repair voids first, and spray or roll the coating to the manufacturer’s specified thickness, because a thin coat of the right product is still the wrong job.
Brick, stone veneer, split-face block, and concrete all absorb water over time, and trapped moisture is what cracks them apart in winter. We test how much water your surface absorbs, then apply penetrating sealers or film coatings suited to the material. Sealing is one of the most cost-effective ways to protect retaining walls, foundations, veneer, and hardscape masonry across Lancaster County.
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.

Lancaster’s hard winters, humid summers, and wind-driven rain put constant stress on exterior and below-grade walls. We select every system based on the substrate, the moisture conditions, and the exposure, so the coating performs for years instead of peeling in two seasons.
Pennsylvania has some of the most publicized stucco failures in the country, and Lancaster County has its share. Most failed stucco from the 1990s and 2000s was not bad stucco. It was missing kick-out flashing, missing weep screeds, and cladding installed tight to the sheathing with no drainage path. Water got in at roof lines and windows, could not get out, and quietly rotted the structure behind a wall that looked fine from the curb.
Keystone Outdoor Solutions addresses the water path before the finish. We check flashing, drainage details, and moisture levels before quoting repair or new installation, and we build those details into every system we apply. We do not skim new stucco over a wet wall and call it fixed. Every coating we install is set up to shed water correctly, which is the difference between a wall that lasts and a repair you pay for twice.
Our Process
Every coating project at Keystone Outdoor Solutions follows a clear process from first visit to final walkthrough. You know what to expect at every stage.
01
We walk your property and inspect every surface you want coated. We check for cracks, spalling, dampness, failed flashing, and prior repairs, and we test moisture where stucco problems are suspected. We listen to your goals and discuss finish options, colors, and budget.
02
Based on the assessment, we recommend the right system for each wall: stucco repair or remediation, parging, elastomeric coating, or sealing. Your written estimate itemizes prep, materials, and application, so you see exactly what you are paying for before any work begins.
03
Our crew pressure washes, routs cracks, fills voids, and masks everything that is not being coated. Stucco coats and coatings go on at the specified thickness with correct cure times between coats. The site is cleaned up at the end of every working day.
04
We walk the finished work with you, check every line and texture against the standard we set, and correct anything that falls short on the spot. You get clear guidance on curing, washing, and recoating timelines, backed by our five-year workmanship warranty.
Lancaster County sits in a true four-season climate. Walls here absorb humid summer air, take wind-driven rain off open farmland, and then go through dozens of freeze-thaw cycles every winter. Any water sitting inside stucco, block, or brick expands when it freezes, which is why unsealed and poorly detailed walls in Lancaster crack, spall, and shed their finishes faster than the same walls would in a milder climate.
Keystone Outdoor Solutions has been working on Lancaster County masonry since 2002. We know which coatings breathe enough for old limestone basements, which systems handle the sun on a south-facing stucco wall, and which sealers actually survive a Pennsylvania winter. Our recommendations come from twenty years of watching products perform on local walls, not from a catalog page.

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 one of South Central Pennsylvania’s most established cities, surrounded by a county that mixes historic stone farmhouses, brick rowhomes, and fast-growing suburbs. Communities like Lititz, Millersville, Manheim Township, East Hempfield, Willow Street, and Strasburg are full of homes where stucco, masonry, and stone surfaces define the look of the property, and where owners invest seriously in keeping them sound.
The county’s climate is hard on those surfaces. Humid summers load walls with moisture, and Lancaster winters freeze and thaw that moisture dozens of times a season, cracking finishes and spalling unprotected masonry. Keystone Outdoor Solutions has been applying stucco and protective wall coatings across Lancaster County since 2002, with a deep understanding of which systems survive here and which ones fail.
FAQ's
Stucco installation in Lancaster, PA typically runs $8 to $14 per square foot for a full three-coat system, depending on wall height, access, prep work, and finish choice. Repairs and patching are priced by the scope of damage rather than by the square foot. Keystone Outdoor Solutions provides free on-site estimates with itemized pricing, so you see exactly what the prep, materials, and application cost before any work begins.
A full three-coat stucco system needs proper cure time between the scratch, brown, and finish coats, which adds roughly six days of drying to the schedule. Most residential stucco projects in Lancaster take one to two weeks depending on size, weather, and detail work. Coatings and sealers are faster, often one to three days. We build realistic cure times into every estimate because rushing stucco is what causes cracking later.
Hairline cracks and isolated damage usually mean repair. Staining below windows, soft or hollow areas, damp interior walls, and high moisture readings point toward water trapped behind the cladding, which means remediation. We test moisture levels and open up suspect spots before quoting, then show you what we find. Many Pennsylvania homes from the 1990s and 2000s have hidden stucco moisture problems, so an honest assessment matters before you spend money.
Many Pennsylvania homes built in the 1990s and 2000s had stucco installed without kick-out flashing, weep screeds, or a drainage path behind the cladding. Water entered at roof lines and windows and stayed there, rotting the sheathing behind walls that looked fine. Lancaster County has plenty of these homes, and buyers and sellers now routinely deal with stucco moisture inspections. We correct the water path first, then apply the finish, which is the fix that actually lasts.
Parging is a thin coat of cement-based mortar applied over basement and foundation walls to give them a smooth, protected surface. It covers rough block, fills minor surface damage, and gives coatings a sound base. If your Lancaster basement walls are dusty, flaking, uneven, or showing white efflorescence stains, a fresh parge coat with a breathable masonry coating will clean up the surface and help it resist dampness.
Surface coatings handle dampness, dusting, and minor surface moisture, and they make basement walls cleaner and brighter. They cannot stop water that is being pushed through the wall by hydrostatic pressure from outside. If your basement takes in standing water, the fix is drainage, grading, or gutter correction, and we will tell you that honestly rather than sell you a coating that will fail. For damp walls without active leaks, our parging and coating systems work very well.
Elastomeric coating is many times thicker than paint and stays flexible after curing, so it bridges hairline cracks and stretches with the wall through Lancaster’s freeze-thaw cycles. Standard exterior paint is a thin decorative film that splits as soon as the surface moves. On stucco, concrete, and masonry walls that see weather, a properly applied elastomeric system lasts years longer and actively sheds water instead of just coloring the surface.
Penetrating masonry sealers on vertical surfaces typically protect for around ten years, while elastomeric coatings commonly perform for ten to fifteen years when applied at the correct thickness over sound, prepared surfaces. Horizontal surfaces wear faster. Surface preparation and application thickness decide most of the lifespan, which is why our process puts so much weight on prep before a drop of product goes on.
Cement stucco and most coatings need temperatures above roughly 40 degrees during application and curing, so the main season in Lancaster runs from spring through late fall. Cold-weather application without proper protection leads to weak, chalky finishes that fail early. If your project lands in winter, we schedule it correctly or use systems rated for the conditions, and we tell you up front what the weather allows.
Yes. Keystone Outdoor Solutions applies stucco, parging, elastomeric coatings, and masonry sealers for homeowners, business owners, property managers, and HOAs across Lancaster County.
