Belgard Home Additions & ADU Nationwide

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

Belgard pavers and hardscape systems used in Los Angeles home additions and ADU projects typically cost $53,100-$153,400 installed for a complete addition, with Belgard-specific paver patio and driveway components running $4,130-$21,240 depending on series and scope. We stock Belgard-compatible hardscape materials and can source OEM or equivalent-grade pavers for same-day project starts on most Los Angeles ADU and home addition jobs. Most homeowners discover their Belgard installation needs attention when settling, staining, or drainage failure appears in the hardscape surrounding their new living space.

Which Belgard Models This Applies To

Belgard’s product lines for residential hardscape in Los Angeles fall into three categories: the Bergerac and Dublin cobble-style pavers common in Silver Lake and Echo Park ADU courtyards, the sleek Lafitt and Mega-Lafitt plank pavers popular in Venice and Mar Vista modern additions, and the Catalina and Victorian pavers used in traditional Pasadena and Altadena home extensions. Each series carries a specific edge profile and spacer lug design that affects compatibility with existing base prep.

To identify your Belgard series, check the paver edge for the molded brand stamp (typically on the spacer lug, not the face) or measure the unit: Bergerac runs roughly 6×6 and 6×9 inches, Mega-Lafitt comes in 4.75×9.5 and 4.75×14.25 inches, and Catalina slabs are 15.75×15.75 or 15.75×23.625. The color code matters too - Belgard’s Los Angeles distribution carries region-specific blends like “Sable Blend” and “Cotswold Mist” that may not match catalog photos from other markets.

We source OEM Belgard through the local distributor in Vernon, but we also stock quality-equivalent pavers from Techo-Bloc when the Belgard lead time runs long or the specific color lot is discontinued. The base material and edge restraint are where most Belgard hardscape failures actually start, not the paver itself, so we quote the full system, not just the surface unit.

Signs Your Belgard Home Additions & ADU Is Failing

• Sunken or uneven pavers near the addition foundation. This usually means the aggregate base compacted poorly or the utility trench backfill settled after the ADU rough-in. In Los Angeles, the clay-heavy soils in the Baldwin Hills and Mid-City areas make this more common than on sandier coastal lots.
• Efflorescence - white powder rising through the paver face. Calcium hydroxide migration from the cement in the pavers or bedding sand. It’s cosmetic, not structural, but in Belgard’s darker color lines it shows dramatically and often prompts replacement calls.
• Joint sand washing out, leaving gaps between units. Polymeric sand failure from premature wetting during installation, or simply age and UV breakdown in south-facing Los Angeles yards. Gaps let water reach the bedding layer, accelerating freeze-thaw damage even in our mild climate.
• Chipped or spalled paver edges, especially on driveway installations. Belgard’s thinner plank pavers (under 60mm) weren’t designed for vehicle loading; we see this on ADU driveway extensions in Koreatown and West Adams where owners added parking without upgrading to 80mm commercial-grade units.
• Standing water 48 hours after rain. Indicates a failed or missing permeable base, or a Belgard installation that wasn’t pitched correctly away from the new addition’s slab. In Los Angeles, this pools against stucco weep screed and causes interior moisture issues that get blamed on the ADU build.

Replacement Cost & What’s Included

The range depends on four factors: whether we’re matching existing Belgard color lots (discontinued blends require full-area replacement), the condition of the aggregate base (reusable or complete re-excavation), access for equipment in tight Los Angeles side yards, and whether the project needs permit coordination with LADBS for the hardscape tied to the addition. Every quote we deliver is a flat written price with line-item scope - under Clause 1 of the Haven Standard, the number you agree to is the number you pay, with signed change orders required before any additional work proceeds.

DIY or Call Us?

There’s no high-tension danger in paver work the way there is with garage door springs or electrical panels, but Belgard installations fail fastest where the prep work is rushed. A homeowner can safely check: whether the settlement is isolated to a few units or widespread, whether the edge restraint is still pinned, and whether drainage flows away from the structure. A rubber mallet and level will tell you most of what you need to know.

Where DIY goes wrong is in the base: compacting in lifts, achieving the right moisture content in the aggregate, and maintaining uniform slope. We’ve been called to redo more Belgard patios in Los Angeles that were installed over 2 inches of bedding sand (it should be 1 inch, screeded) than we can count. The paver itself is the easy part; the substrate is where the money and skill go. If the failure involves your ADU’s waterproofing integration, the weep screed, or any gas or electrical lines trenched beneath the hardscape, that’s permit territory and trained crew work.

Call (213) 652-7670 and we’ll come out, document the condition with our standard photo record, and give you a written price before any work starts.
