Belgard Home Additions & ADU Nationwide

Belgard Home Additions & ADU: The Los Angeles Owner’s Guide

Belgard home addition and ADU projects in Los Angeles typically run $53,100 – $153,400 for a full build, depending on square footage, foundation work, and finish level. We install Belgard pavers, retaining walls, and outdoor living systems as part of larger addition and ADU scopes, and we can usually get your project priced within a week of the site visit. Most owners come to us after a previous contractor left the hardscape unfinished, sloped wrong, or spalling two years in, and the fixing always starts with the same question: what failed first, the base or the Belgard product itself.

One thing worth saying clearly: Penhallow Remodeling is an independent remodeling contractor. We are not affiliated with Belgard, and we don’t pretend to be. We use their products because the pavers and wall units hold up well in Los Angeles weather, and because our buyers expect brand-name materials behind the written guarantee.

Which Belgard Models This Applies To

Belgard makes hundreds of SKUs across paver lines, wall blocks, and outdoor living components. The compatibility questions we get most in Los Angeles involve the Catalina, Dublin Cobble, Lafitt, and Mega-Arbel paver lines, plus Belair Wall and Weston Wall block for retaining walls and seat walls. Your product’s series name is usually stamped on the packaging label, but on installed product that label is long gone. The reliable identifiers are the unit’s face dimensions and thickness: Mega-Arbel runs large-format at roughly 24″ x 24″ with a 3-1/8″ thickness, Dublin Cobble is a smaller modular unit around 6″ x 9″, and Lafitt is a slab-style paver that reads closer to a natural stone finish.

The OEM-versus-aftermarket question comes up a lot. For Belgard specifically, we recommend matching the original series when the product is still in production. Belgard lines change subtly over the years, and a paver made today won’t always sit flush against a paver made in 2016 even within the same series name. That’s the compatibility gotcha that trips up well-meaning DIY runs to the local hardscape yard. If the original line is discontinued, we’ll match color and dimension with the closest current product and tell you straight that it won’t be a perfect match. That honesty gets written into the quote.

Signs Your Belgard Hardscape or ADU Addition Is Failing

• Pavers rocking underfoot: A paver that shifts when you step on it means the sand bed underneath has eroded or washed out. In Los Angeles, this is almost always drainage related, especially around downspouts and patio edges where runoff pools. The fix is resetting the affected area, not just sweeping more sand into the joint.
• Joint sand disappearing between pavers: If the gaps between stones are getting deeper every year, water is getting under the system. That water softens the base, and the cycle repeats. This is the first thing we check on hillside lots in the San Fernando Valley, where runoff never gives up.
• Retaining wall units tilting or bulging out of plane: A wall block that’s leaning forward means the deadman anchors or geogrid behind it has failed, or the wall was built without proper drainage gravel at the base. This one gets worse quietly, and by the time you see it, the repair often means rebuilding the lower courses.
• Efflorescence or white streaking across the paver face: That white powder is salt being pulled through the concrete by moisture. It’s cosmetic in most cases, but it tells you water is trapped somewhere it shouldn’t be. In Los Angeles’s dry-wet cycles, this is more common on shaded patios that never fully dry out.
• Settlement dips near the foundation or along the ADU slab edge: If the pavers have dropped an inch or more next to a new addition or ADU foundation, the structural backfill wasn’t compacted in lifts. That’s not a Belgard issue at all. That’s a preparation issue, and it means pulling up the sunken section, recompacting, and relaying the product.

Replacement Cost & What’s Included

For Los Angeles work, a partial Belgard paver reset or hardscape repair falls on the low end of the spectrum, usually $4,130 – $12,980 depending on square footage, while full addition and ADU projects sit in the $53,100 – $153,400 range. What separates those numbers is the base work. If the existing soil is stable and the issue is isolated, the repair is quick. If the base has failed or the slope is fighting you, the digging and recompacting become the real cost driver, not the pavers themselves.

Every quote includes the product, the labor, the disposal of failed material, and a written line-by-line price before you sign anything. The number on day one is the number on the invoice. And if the work fails inside 365 days, we come back and fix it at no charge under the Done Right Promise. No re-inspection fee, no second invoice. That promise is written into every project we do in Los Angeles.

DIY or Call Us?

There are a few things you can safely check: walk the area and mark every loose paver with sidewalk chalk, take photos after heavy rain to see where water pools, and dig one test spot at the edge to see whether the base material is crushed rock or just sand over dirt. That information helps us price faster. What you shouldn’t do is start pulling pavers off a retaining wall or digging next to a loaded foundation. The danger there is real: a wall under load can shift while you’re working it, and a undermined paver edge at the top can drop stones you weren’t expecting onto your feet.
