Johnson City Concrete & Masonry serves Unicoi, TN homeowners with stone veneer installation, retaining wall construction, and foundation repair. We have worked throughout Unicoi County since 2015 and understand the hillside lots, freeze-thaw concrete damage, and older housing stock that shape masonry work in this tight-knit mountain community.

Many Unicoi homes have plain concrete block or older wood siding exteriors that were always intended to be finished with something more durable. Stone veneer gives these homes the look of natural stone at a fraction of the weight - and in this mountain setting, natural stone fits the character of the area. A proper installation here requires a moisture barrier that can handle the area's high annual rainfall and freeze-thaw cycles. See what goes into a lasting installation on our stone veneer installation page.
Unicoi properties on sloped or hillside lots deal with water that runs toward the home from above and soil that shifts with every wet season. A retaining wall built without proper drainage will fail here - water pressure behind the wall has nowhere to go, and freeze-thaw cycles expand that pressure into cracks. We build walls with footer depth, gravel backfill, and weep hole spacing calibrated to the slope and the volume of water this mountain valley sees in a typical spring.
Crawl space foundations are the norm under Unicoi homes, and the mountain terrain makes them particularly exposed to moisture. Hard freezes push crawl space piers and block courses out of position over years of frost heave, and homes built on hillsides can see concentrated drainage against the uphill foundation wall. Sticking doors and uneven floors are usually the first signs a homeowner notices - by the time you see those, the foundation has been moving for a while.
At 1,600 feet in the Appalachian Mountains, Unicoi's winters are cold enough to crack mortar joints in a single season if water is already in the joint. Many homes here were built before 1980, and their mortar has never been touched. Tuckpointing replaces the deteriorated material before freeze-thaw cycles open the joint wide enough to let water into the wall cavity - where it does far more damage than a surface repair can fix.
Unicoi homes with fireplaces put their chimneys through significant seasonal stress - cold mountain winters on the outside, fire heat on the inside, and heavy annual rainfall hitting the cap and crown year-round. A cracked or missing chimney cap is one of the most cost-effective repairs a homeowner can make, because an open flue collects water that then works down through the liner and mortar during every winter freeze. We check the full stack, not just the visible problem area.
Wood-frame homes dominate Unicoi, but older properties near the town center and along the Nolichucky River corridor sometimes have brick elements that have been through decades of mountain weather. When mortar fails and water gets behind a brick face, the freeze-thaw cycle spalls the face off - sometimes quickly. Matching the original brick on an older Unicoi home takes sourcing effort, and we do that work before starting the repair so the finished result does not look patched.
Unicoi sits in a mountain valley in Unicoi County at roughly 1,600 feet elevation, tucked between Erwin and Johnson City along the Nolichucky River. The elevation brings real winter cold - temperatures regularly drop below freezing from December through February, and the area sees freeze-thaw cycles throughout late fall and early spring. That repeated expansion and contraction puts stress on any masonry surface, concrete driveway, or retaining wall on the property. The area receives 45 to 50 inches of rain per year, and because the valley is ringed by steep slopes, much of that water runs off the surrounding terrain and collects near homes rather than draining away cleanly. A homeowner in Unicoi deals with both cold stress and persistent moisture at the same time - a combination that is harder on masonry than either one would be alone.
The housing stock in Unicoi adds a layer of complexity. Most homes were built before 1980, and a large share date to the mid-20th century or earlier. These are older wood-frame homes with crawl space foundations and exteriors that have been through a lot of seasons without major renovation. Sloped lots are common across town - the mountain valley terrain leaves very little flat ground - so driveways, walkways, and retaining walls are under constant slope-related stress in addition to the cold and wet. Homeowners in Unicoi tend to be long-term residents who take their properties seriously and want repairs that hold up, not patches that fail after the next hard winter.
Our crew works throughout Unicoi regularly, and we understand the local conditions that affect masonry work here. Unicoi sits about 10 miles from Johnson City, and many residents commute to the city for work while living in a quieter, more rural setting. The properties we see most often in this area are older single-family homes on wooded lots, often with hillside grading that requires careful attention to drainage whenever masonry work touches the foundation or yard. Because Unicoi is within Unicoi County, permit inquiries for structural work go through the Unicoi County building department.
Iron Mountain rises above Unicoi and is part of the Appalachian Trail corridor that passes through this part of northeast Tennessee - nearly every homeowner in town can see it from their yard. The Nolichucky River runs along the valley floor and is known locally for fishing and kayaking. Homes near the river deal with higher moisture conditions than those up on the ridges - a difference that matters when assessing crawl space foundations and drainage around masonry. We also serve neighboring Erwin, the county seat a few miles south, where the same terrain and climate create similar masonry demands on a similar older housing stock.
Word-of-mouth matters in a town this size. Unicoi residents are careful about who they bring onto their properties, and we take that seriously. When we work on a home here, we give you a clear picture of what we found, what we did, and what to watch for - no surprises in the final invoice and no disappearing after the job is done.
Call us or use the contact form. We respond within 1 business day and ask a few questions about what you are dealing with - location of the problem, age of the home, and anything you have already noticed. You do not need to know the technical term for what is happening. Just describe what you see.
We come to your Unicoi property, look at the area in question, and check the surrounding conditions - drainage, slope, access, and anything adjacent that affects the job. You get a written estimate that explains what we recommend and why. For stone veneer or larger projects, we discuss material options at this visit so there are no surprises at selection time. The estimate is not a commitment - you decide what comes next.
We pick a date that works for you and watch the weather forecast as the day approaches. At 1,600 feet in the mountains, cold snaps and rain events can push a schedule by a day or two from November through March. We communicate that clearly in advance - no day-of surprises. Spring and early fall are the most reliable windows for exterior mortar and veneer work in Unicoi.
When the work is done, we clean up the site and walk you through what was completed. We explain the curing window for any fresh mortar or veneer, point out anything you should keep an eye on, and answer any questions before we leave. You do not need to be present for the full job, but we do ask that you be available for the final walkthrough.
We serve Unicoi and all of Unicoi County. Reach out and we will get back to you within 1 business day with a clear answer - no runaround, no upsell.
(423) 672-1860Unicoi is a small town in Unicoi County, Tennessee, with a population of roughly 3,500 to 4,000 people. The town sits in a narrow mountain valley between Erwin and Johnson City along the Nolichucky River, with Iron Mountain rising to the east and the surrounding Appalachian ridges defining the landscape on all sides. Almost all housing is single-family detached homes on individual lots - there are very few condos, apartment complexes, or townhomes. Most properties have yards, driveways, and outbuildings, and a significant share are on hillside terrain that requires retaining walls, graded driveways, and attention to drainage.
The town has a close-knit, rural character despite its proximity to Johnson City. Long-term homeownership is common - many residents have lived here for decades, and homes have often been in the same family for generations. The housing stock reflects this: most homes were built before 1980, and many have never had a major exterior renovation. Nearby Elizabethton to the north is a larger community in Carter County that we also serve, with its own mix of older brick homes and hillside residential properties.
