Why Jacksonville Homeowners Choose Unilock Construction
Elmstead Remodeling Jacksonville is an independent contractor providing Unilock paver and wall system installation, repair, and Jacksonville Unilock service across Jacksonville, FL. We work on Brussels Block driveways, Richcliff patios, Beacon Hill Flagstone walkways, and U-Cara retaining walls, and we see the same failure patterns repeat across Northeast Florida: settling from sandy soils, efflorescence from coastal humidity, and joint sand washout after summer thunderstorms. Our crews fix these issues with genuine Unilock units when the line is still in production, and we repair the underlying base, not just the surface. Call (904) 643-6243 for a free estimate on Unilock work anywhere in Jacksonville.
We are not affiliated with or authorized by Unilock, and we say that plainly because it matters. What we are is a local remodeling contractor that has pulled apart enough failed paver installations in Jacksonville to know exactly what holds up and what does not. Graham Stein, owner of Elmstead Remodeling Jacksonville, writes every scope of work in plain language: materials listed by name, labor broken into stages, no allowance line items that quietly grow. If a Unilock patio is sinking in Avondale or a paver driveway is spreading in Mandarin, the fix starts with a written price before any work begins.
Why Trust Elmstead Remodeling Jacksonville for Your Unilock Construction?
Trust with Unilock work comes down to one thing: knowing what is under the pavers. Anyone can lay stones on sand. Keeping them flat through Jacksonville’s wet-dry cycles, intense UV, and sandy subgrade takes a crew that has excavated, recompacted, and re-laid enough paver jobs to know when a base is failing before the surface shows it. Our technicians have pulled up Unilock installations across Jacksonville’s older neighborhoods and newer master-planned communities alike, and we have learned the same lesson in all of them: the failure is almost never the paver. It is the prep underneath it.
Graham grew up in Los Angeles and learned construction fundamentals at Los Angeles Trade-Technical College before spending close to two decades on residential and light commercial projects across Southern California. For the past several years he and his crew have worked steadily across Jacksonville, including kitchen and bathroom rebuilds in the Avondale neighborhood where older Craftsman bungalows demand careful demo and patient trim work. That patience carries over to hardscape. We do not rush a base because the weather is closing in. We tarp the excavation, wait out the rain, and compact in lifts. We also stock color-matched polymeric sand and edge restraints locally so a repair call does not turn into a two-week parts wait.

Common Unilock Construction Problems We Fix in Jacksonville
- Settling and heaving on sandy soils. Jacksonville’s subgrade varies block to block, and in neighborhoods built on loose sandy fill, an inadequately compacted base will settle within two or three wet seasons. Brussels Block driveways in Arlington and the Westside often show lippage at paver joints and low spots that pond after rain. We fix this by removing the affected area, recompacting the base in lifts, and re-laying the same pavers wherever possible. The pavers themselves are rarely the problem.
- Efflorescence on coastal and high-humidity lots. White salt deposits on Beacon Hill Flagstone and other Unilock lines are common within a few miles of the coast and along the St. Johns River, where humid air keeps moisture moving through the paver body. It is not permanent staining in most cases, and it is not a product defect. We clean it with the appropriate efflorescence remover and then address the moisture path so it does not return in the same pattern.
- Edge restraint failure on driveways and pool decks. When a Unilock paver driveway spreads at the edges, the cause is usually a missing or undersized edge restraint, not the pavers themselves. Heavy vehicle loads and seasonal wetting-drying cycles push pavers outward over time. We re-set the edge with proper restraint and re-tension the field so the pattern stays locked.
- Polymeric sand washout and joint erosion. Jacksonville’s summer thunderstorms drop intense rain in short bursts, and if the joint sand was never activated properly or the wrong grade was used, it washes out within a season or two. We see this constantly on Richcliff patios and walkways, with weeds sprouting through open joints and pavers starting to shift. The fix is proper joint prep, the right sand for the joint width, and correct activation with controlled water.
- Sunken U-Cara wall blocks and retaining wall bulges. The U-Cara wall system works well when the base course is set on compacted aggregate and the wall has proper drainage behind it. When it bulges or a single block sinks, water is usually the culprit. Jacksonville’s high water table in neighborhoods like Riverside and Avondale means groundwater is often present at shallow depths, and a wall without weep drainage or clean backfill will fail from hydrostatic pressure, not from the blocks themselves.
Unilock Parts & Our Repair-vs-Replace Approach
We use genuine Unilock pavers and wall units for color-matched repairs whenever the product line is still in production. Brussels Block, Richcliff, and Beacon Hill Flagstone are all active lines, so matching a recent installation is straightforward. For discontinued blends or colors that have shifted from years of UV exposure, we source high-quality compatible aggregate pavers and color-matched polymeric sand to blend the repair into the surrounding field. A patch that calls attention to itself is a failed repair, and we would rather tell a homeowner the honest truth about a discontinued color than pretend a poor match is good enough.
We recommend full replacement only when the structural base has failed or the heaving is severe enough that spot repair would be uneconomical over the long term. If we can pull the affected section, rebuild the base, and re-lay the original pavers, that is almost always the right call. It preserves the original look and costs less than a full tear-out. If you are not sure which path makes sense for your Jacksonville paver job, call (904) 643-6243 and we will walk you through what we are seeing.
Our Unilock Service Process – Step by Step
- 1
Diagnosis and site walk. We start by looking at the whole installation, not just the visible problem. For a sunken paver area, we check the pattern around it, the edge restraints, the drainage path, and the subgrade. For efflorescence, we ask about irrigation overspray and recent weather. The goal is to name the actual cause, not treat a symptom.
- 2
Written scope and price. Before any work starts, you get a written price with materials listed by name, labor broken into stages, and no allowance line items that quietly grow. Graham writes these scopes himself. If it is a repair, the scope says exactly which pavers come up, how deep we excavate, and what goes back in. If it is a new paver driveway or patio, the scope includes base depth, geotextile fabric, edge restraint type, and joint sand specification.
- 3
Site protection and preparation. Our crews use shoe covers and drop cloths inside the house if the job involves any interior access, and we lay protection on adjacent hardscape and landscape areas. Quiet tools during family rest hours where possible. We ask before moving anything, and we photograph the protected areas so you can see exactly what we did.
- 4
Excavation, base rebuild, and re-installation. This is where most Unilock repairs succeed or fail. We excavate to the depth the job requires, install geotextile fabric over compacted aggregate where the subgrade warrants it, compact in lifts, and then re-lay or install the pavers with proper joint spacing and edge restraint. For retaining wall work, we install clean drainage aggregate and weep drainage behind the wall so groundwater does not push it forward.
- 5
Joint sand activation and clean-up. Polymeric sand is swept into the joints, compacted, and activated with controlled water. Too much water is as bad as too little. We photograph the finished clean-up before the crew leaves, because that photo is your proof the site was left right.
- 6
365-Day Done Right Promise. Every completed project is covered by our 365-Day Done Right Promise. If something is not done right after the job is complete, we make it right. That is not a warranty buried in fine print; it is stamped on the scope of work.

AfterUnilock Products We Service & Install in Jacksonville
We install and repair the Unilock lines most common in Northeast Florida hardscapes. Brussels Block is the workhorse for paver driveways and high-traffic areas, with its tumbled edges and tight joint spacing. Richcliff shows up on patios and pool decks where a cleaner, more contemporary surface is wanted. Beacon Hill Flagstone works well for walkways and garden paths. The U-Cara wall system handles retaining walls, seat walls, and planter surrounds. We stock color-matched polymeric sand, edge restraints, and repair pavers for these lines locally, including Unilock in Orange Park and across Jacksonville, so most repairs do not wait on shipping.

FAQs – Unilock Construction Service in Jacksonville
Is Elmstead Remodeling Jacksonville authorized by Unilock?
No. We are an independent construction and remodeling contractor with extensive hands-on experience installing and repairing Unilock products throughout Jacksonville. We are not affiliated with, authorized by, or endorsed by Unilock, and we say that clearly so there is no confusion. Our expertise comes from doing the work, not from a manufacturer relationship.
How do you match discontinued Unilock colors on a 2010-era Richcliff patio after Hurricane Ian displaced several pavers?
We start by pulling an undamaged paver from an inconspicuous area, cleaning it, and comparing it against current Richcliff production colors and our inventory of stock pieces from past jobs. If the original color is still in production, we order genuine Unilock units. If it has been discontinued or UV has shifted the color significantly, we source a compatible aggregate paver and use color-matched polymeric sand and targeted sealing to blend the patch. We will tell you if a perfect match is not possible before we start, not after. Call (904) 643-6243 and we can look at your specific patio, including Unilock repair in Atlantic Beach and surrounding areas.
Will Unilock pavers crack under the weight of my SUV on a paver driveway in Jacksonville’s clay pockets?
Unilock paver driveways can handle passenger vehicle loads without cracking when the base is built correctly. The pavers themselves are engineered for vehicular traffic. What fails in Jacksonville is the base underneath when it is undercompacted or too thin for the subgrade. In clay pockets, we use a deeper aggregate base, geotextile fabric, and proper compaction in lifts so the pavers do not flex or settle. A properly built Unilock driveway on the right base will carry your SUV without cracking for years. If you are planning a new paver driveway in Jacksonville, call (904) 643-6243 and we will price the base depth your soil actually needs.
What causes white powder on my Unilock Beacon Hill Flagstone walkway, and can you remove it?
Efflorescence is the technical term, and in Jacksonville’s humid coastal air it is common. Water moves through the paver body, carries dissolved salts to the surface, and leaves a white residue when the water evaporates. It is not permanent staining in most cases and it does not mean the pavers are defective. We remove it with an appropriate efflorescence cleaner and then look at the moisture path: irrigation overspray, poor drainage, or a low spot that holds water. If we do not address the moisture source, the white powder returns. Call (904) 643-6243 and we will assess your walkway.
Can you repair just a sunken U-Cara wall block in my retaining wall, or do I need to rebuild the whole wall?
In most cases, we can repair a single sunken or displaced U-Cara block without rebuilding the entire wall. We remove the affected block and the few around it, re-set the base course on compacted aggregate, check the drainage behind the wall, and re-stack with proper alignment and backfill. If the wall shows multiple points of movement or a bulge, that usually indicates a broader drainage problem, and we will tell you honestly whether a repair will hold or whether the wall needs to be rebuilt. You will get that assessment in writing before any work starts.
Is it normal for the sand between Unilock pavers to wash away every summer in Jacksonville, and how do you stop it?
It is common, but it is not normal in the sense that it should be happening every year. Polymeric sand that is properly installed and activated should last for years. When it washes out every summer, something is wrong: the wrong sand grade for the joint width, improper activation with too much or too little water, poor drainage concentrating runoff through the joints, or a base that is moving and opening the joints. We diagnose the specific cause, correct it, and re-sand with the proper product. Call (904) 643-6243 for an exact assessment and quote, and our estimates are free.
