Belgard Home Additions & ADU: The Fort Myers Owner’s Guide
A Belgard home addition or ADU in Fort Myers typically runs $45,000 to $130,000 installed, and most detached units are permitted and framed within six to ten weeks once engineering clears. Homeowners usually reach out when their existing patio or driveway pavers are showing settlement, or when the original Belgard block used on a lanai wall has started spalling from years of direct Florida sun and salt air. It is rarely the block itself that fails outright. More often, the base underneath washed out during a heavy summer storm, or a sprinkler line leaked behind a retaining course, and now everything has shifted enough to crack coping and open joints. We stock Belgard-compatible components across the Dimensions, Dublin, and Arbel lines, and we carry matching edge restraint, polymeric sand, and base aggregate on every truck.
Which Belgard Models This Applies To
Home additions that tie into an existing Belgard hardscape in Fort Myers usually involve one of three product families. The Belgard Dimensions series is the most common for paver patios that get expanded into an ADU foundation skirt or outdoor kitchen. Dublin cobble and Arbel stone are the other two we see regularly, especially on older Fort Myers homes where the original installer used a three-piece modular pattern. Matching requires more than just grabbing the same color name. Belgard changes dye lots over time, and UV exposure in Southwest Florida fades surface pigment faster than what you would see in a northern climate. That means a “Grayson” paver installed in 2019 next to a factory-fresh “Grayson” block will not blend without a polymeric sand that bridges the color gap.
When we quote a Belgard ADU addition, we pull a field sample from your existing hardscape first. We check the mold pattern on the bottom of the paver, the chamfer profile, the thickness tolerance, and the joint width. Dimensions pavers are made in both a standard 60mm and a heavier 80mm gauge. If your existing patio used 60mm pavers and you want the ADU driveway apron rated for vehicle loads, we will recommend stepping up to the 80mm gauge and planning a transition course so the two sections read as intentional rather than mismatched. For retaining walls that double as seating, we specify Belgard’s tandem wall system because it gives us the pin connection needed for taller courses when the ADU sits on a sloped Fort Myers lot.
Signs Your Belgard Home Addition or ADU Pavers Are Failing
- Widening joints between pavers near downspouts. This is base material washing out. We see it most in Fort Myers neighborhoods like McGregor and Whiskey Creek where older homes have undersized gutters and no splash blocks. Water concentrates at one corner of the Belgard patio and erodes the aggregate base over a single rainy season.
- Efflorescence that keeps coming back after cleaning. A chalky white haze on Belgard block signals moisture moving through the wall from behind. It is not a surface problem. It means the drainage aggregate or weep holes are clogged and hydrostatic pressure is pushing mineral salts out the face of the block. Ignore it and the block face will eventually spall.
- Sunken pavers in a straight line across the ADU entry. That line is almost always a collapsed irrigation pipe or an old tree root that rotted out after a lot-clearing. The pavers themselves are fine, but the void underneath will keep growing until we pull the section and recompact the base.
- Retaining wall leaning out after a storm. Fort Myers gets hit with tropical downpours that saturate the soil behind the wall in hours. If the original installer skipped geogrid reinforcement on a wall over three feet, the block face will start to lean. Belgard Dublin and Arbel walls can be rebuilt with proper grid and a gravel chimney drain behind them.
- Edge restraint popping up around the perimeter. The plastic edging spikes have lost their bite in sandy Lee County soil. Without solid edge restraint, the outer paver courses spread, joints open, and the whole section loses interlock. We replace failed edge restraint with a concrete haunch on every Belgard project because Florida sand does not hold plastic spikes long-term.
Replacement Cost & What’s Included
A full Belgard addition or ADU hardscape tie-in in Fort Myers falls between $45,000 and $130,000, depending on square footage, wall height, and how much of the existing base needs to be excavated and rebuilt. At the lower end of that range, you are looking at a simple paver patio expansion with no retaining wall, using a standard three-piece Belgard pattern on a fresh compacted base. At the upper end, we are building a detached ADU with a block stem wall, full Belgard paver driveway approach, a sitting wall with built-in lighting, and re-grading the lot for positive drainage.
Every quote includes a line-item breakdown: demolition and haul-off of failed sections, base excavation to 8 to 10 inches, geotextile fabric separation, compacted limerock base, bedding sand, Belgard block or paver material matched to your existing color, edge restraint, polymeric sand in the joints, and a final compaction pass. Our work is covered by the 730-Day Done Right Promise. If something settles or shifts during that window, we come back and make it right at no charge. Upfront pricing means the number you see on the estimate is the number you pay, no change orders buried in the fine print.
DIY or Call Us?
What you can safely do yourself is spot-check the condition. Walk the perimeter and look for any edging that has pulled free. Note where water pools after a rain. Run a hose at low pressure along the base of a retaining wall and watch whether water drains out through the weep holes or backs up behind the block. That kind of inspection helps you understand the scope before anyone quotes the job.
The actual rebuild is not a weekend project. A Belgard wall over three feet tall carries a lateral load that will push it over if the geogrid is not embedded at the right elevation and compacted in lifts. Cutting pavers to fit against an ADU foundation and maintaining the correct joint pattern takes a wet saw and experience matching Belgard’s specific chamfer profile. And in Fort Myers, any ADU addition that attaches to or impacts the primary structure’s foundation requires a permit with Lee County or the City of Fort Myers building department. We pull those permits and schedule the inspections so the final sign-off is clean. Call (844) 638-7249 and we will walk the property together, pull samples to match the color, and give you an exact number.
FAQs
How long do Belgard pavers last in Florida?
The Belgard block itself can last 30 years or more, but the functional lifespan of the installation in Fort Myers depends entirely on the base. A properly compacted limerock base with geotextile separation underneath will hold for decades. A thin sand-only base on clay will fail in five to seven years.
Can you repair just the sunken section, or does the whole patio need to come up?
We can often remove and reset only the affected area if the edge restraint is still solid and the pattern is one we can match. We saw-cut the perimeter, excavate the bad section, rebuild the base, and re-lay the pavers. For a small settle zone, this can save thousands compared to a full replacement.
How long does a Belgard driveway addition take?
A typical paver driveway addition for an ADU in Fort Myers runs three to five working days from excavation to final compaction. That assumes dry weather, which during the rainy season can add a day or two if we need to cover open excavation overnight.
Do you stock Belgard pavers in Fort Myers, or do you special-order them?
We keep the most common Dimensions, Dublin, and Arbel colors on hand in our Fort Myers yard, including Grayson, Danville Beige, and Rio. If your project needs a less common color or a specialty block profile, we order direct from Belgard’s Florida distribution center and typically have it on site within a week.
