Belgard Home Additions & ADU: The Jacksonville Owner’s Guide
Belgard home additions and ADU projects in Jacksonville typically run between $45,000 and $130,000 installed, depending on square footage, foundation work, and the Belgard wall block, paver, and permeable pavement systems specified in the plan. We stock and install Belgard hardscape materials for accessory dwelling unit foundations, walkways, and patio connections, and we can source the specific Belgard product line your addition calls for within a week in most cases. The part failure or material mismatch homeowners usually discover is a paver or wall block that has settled, cracked, or separated at the seam where the new addition meets the existing home, often after Jacksonville’s summer rain season pushes water under the base layer.
Most families find us because the Belgard retaining wall behind the addition has started leaning, or the Belgard paver base is holding water against the foundation. The fix is rarely just replacing one block. It’s diagnosing the base, the drainage layer, and the slope so the repair lasts through the next decade of Florida weather. Graham Stein has walked enough of these Jacksonville additions in neighborhoods like Avondale, San Marco, and Mandarin to know the difference between a materials problem and a prep problem.
Which Belgard Models This Applies To
Belgard organizes its hardscape products into families rather than model numbers the way an appliance brand would. The main lines we see spec’d on Jacksonville home additions and ADUs include the Catalina slab and paver series, the Dublin wall system, the Weston wall block, and the Mega and Tandem permeable paver lines for driveway and walkway connections. Each family has its own dimension standard. Catalina pavers run 80mm thick for pedestrian use, Mega pavers typically run 80mm thick as well but use a larger face dimension, and Dublin wall blocks step down in a tongue-and-groove profile that locks differently than the Weston series, which uses pins or lips depending on the generation.
The compatibility gotcha in Jacksonville is the older Belgard Dublin wall block. Pre-2015 lots used a narrower top cap with a different receiving groove, and those caps are no longer in production. If a section of wall cap is cracked on an older addition, we match the remaining caps and source a compatible replacement from Belgard’s current inventory or fabricate a cap from matching material. It’s a small detail that changes the whole repair price. Tell us the wall height, the block face dimension, and whether the caps lip over the front or sit flush, and we can identify the series before the first visit.
OEM Belgard products carry the manufacturer’s warranty and keep your addition’s hardscape matching the original color, texture, and structural intent. For some applications, a quality aftermarket block from a Jacksonville supplier meets spec, but the color match on Belgard’s tumbled finish is specific enough that we recommend OEM for any visible section. Elmstead Remodeling Jacksonville is an independent service provider, not affiliated with Belgard, but we stock the most common Belgard paver and wall block profiles on our truck and order the rest directly from regional distributors.

Signs Your Belgard Home Additions & ADU Is Failing
Most owners don’t need a contractor to tell them something is wrong. The signs are visible from the kitchen window, and they usually start after a heavy Jacksonville rain. Here’s what we look for:
- Water pooling against the foundation where the Belgard pavers meet the house. This means the base layer has settled below the intended slope, and the water isn’t reaching the drainage channel. In Jacksonville’s sandy-loam soil, settlement happens faster than homeowners expect, especially where a downspout discharges near the paver edge.
- A retaining wall that leans outward or shows a horizontal crack near the midpoint. This is hydrostatic pressure building behind the wall, usually because the drainage aggregate or weep hole was skipped during installation. Gravity doesn’t fix itself, and neither does a leaning wall.
- Individual pavers that rock underfoot or sit proud of the surrounding surface. The base has compacted unevenly beneath them. One rocking paver is a call for a leveling repair; a whole section means the sub-base needs reconstruction.
- Gaps opening between the addition’s exterior wall and the hardscape edge. This can signal the addition’s foundation has settled separately from the paver apron. It’s not always structural, but it always needs a look before water finds the opening.
- Efflorescence or white staining creeping across the Belgard wall. Florida humidity pushes mineral content through the block. It doesn’t mean the wall is failing, but if it appears alongside any of the signs above, the moisture path behind the wall needs attention.

AfterReplacement Cost & What’s Included
The price of a Belgard home addition or ADU hardscape repair in Jacksonville varies widely, and we write every estimate the same way: material line items named by product family, labor broken into stages, and no allowance line items that quietly grow. A paver section repair on an existing addition runs $3,500 to $11,000 depending on square footage. A full Belgard paver driveway entry for an ADU runs $7,000 to $18,000. For a new home addition structure with Belgard exterior hardscape, the full project range is $45,000 to $130,000, and an ADU build runs $90,000 to $220,000 when it includes foundation, structure, finishes, and the surrounding hardscape.
Every quote includes the written price before any work starts, the exact Belgard products we’ll use, the disposal of any failed material, and our 365-Day Done Right Promise. If something isn’t right after the job is done, we make it right. That’s the whole promise, and it’s on the estimate in writing. We never charge separately for shoe covers, drop cloths, or the photo of the clean-up we take before the crew leaves.
DIY or Call Us?
For a single rocking paver or a cracked cap block on flat ground, a patient homeowner with a mallet and a bag of polymeric sand can often reset the piece. That’s an honest repair. You can safely check the slope with a four-foot level, clear the drainage channel, and re-apply sand to the joints if the base feels firm. What you shouldn’t do is rebuild a retaining wall or cut pavers against the house without a base assessment. A leaning Dublin or Weston wall under load is a structural hazard, and if it comes down while someone is working on it, the injury isn’t worth the savings. Same goes for any repair within hand’s reach of the addition’s foundation waterproofing.
If the base has settled, if the wall leans, or if water is entering the addition, call (904) 643-6243. We’ll give you a written price before any work starts, not after the crew arrives.
FAQs
Belgard pavers and wall blocks typically last 30 to 50 years in Jacksonville, but the base beneath them usually needs attention at the 15- to 20-year mark. Florida’s rain and humidity shorten the life of the base layer faster than the block itself. Call (904) 643-6243 and we’ll tell you if your repair is a base fix or a full reset.
Yes, a leaning Belgard wall can often be repaired by rebuilding just the affected section after correcting the drainage behind it. If the blocks themselves are intact, we salvage them, re-compact the base, and reset the wall with the right aggregate. The exception is when the wall is load-bearing or the blocks have fractured, which changes the repair scope.
Most paver leveling and wall section repairs take one to three days once the material is on site. A full paver apron replacement around an addition typically runs four to seven days, and we schedule around your family’s noise tolerance, keeping quiet tools during nap and school hours where possible.
We keep the most common Belgard paver and wall profiles on our truck and order project-specific material from regional distributors, which means most repairs start within a week. We carry OEM Belgard for visible sections, and we also work with KraftMaid, Cambria, and Silestone for interior finishes if your addition or ADU needs cabinetry and countertops too.
