Cambridge Pavers Home Additions & ADU: The Orange County Owner’s Guide
Cambridge Pavers home additions and ADUs in Orange County typically run $45,000 to $130,000 for a permitted, turnkey build, depending on square footage, foundation work, and utility runs. We install and service Cambridge Pavers hardscaping as part of larger addition and ADU projects across Orange County, and we stock matching pavers on our trucks for tie-ins where new paving meets existing patios, walkways, and driveways. Most owners call us when they realize their existing Cambridge paver surfaces don’t match the footprint of an addition, or when a slab pour for an ADU leaves a mismatched edge against the original hardscape.
That’s where this page earns its keep. You’ve got a Cambridge Paver surface that has to integrate with new construction, and you need a crew that understands both the structural side and the finishing side. We do.
Which Cambridge Pavers Models This Applies To
Cambridge Pavingstones with ArmorTec manufactures three primary product lines that show up on Orange County properties: the Ledgestone series (tumbled edges, irregular shapes), the RoundTable series (cobblestone profiles), and the Maytrx series (contemporary linear forms). Each line uses different joint widths and edge profiles, which matters when you’re tying new work into old. The Ledgestone series, for example, has a 6% to 8% size variance per stone, so matching it to a clean concrete edge requires a soldier course or a buried aluminum edge restraint. The Maytrx line locks up tight, but it demands a specific 1/8-inch joint; if your installer floats that to 1/4 inch, the interlock fails and you’ll see heaving within two seasons.
Cambridge stamps a four-digit date code on the underside of most pavers. Take a photo of it before you call anyone. That code tells us which production run you have, and whether the current dye lot still matches what’s on your property. This matters more in Orange County than people expect: UV exposure fades pavers differently in Irvine than it does in coastal Newport Beach, so a paver poured in 2019 won’t match a 2024 run even if it’s the same SKU. We carry OEM Cambridge pavers alongside proven aftermarket equivalents for the common sizes, but for color-matched tie-ins, OEM is the only route that won’t leave a visible seam.
We also work with kraftmaid cabinetry, cambria countertops, and silestone surfaces on ADU interiors, so the paver-to-foundation-to-cabinet handoff stays under one roof.

Signs Your Cambridge Pavers Home Additions & ADU Is Failing
- Edge separation at the addition seam. When a new slab or foundation is poured against older Cambridge pavers without a proper expansion joint or edge restraint, the pavers start creeping away from the concrete within the first year. You’ll see a widening gap, usually 3/8 inch to 1 inch, along the pour line.
- Heaving or sinking near the new foundation. OC soil moves. Clay-heavy areas like Fullerton and Placentia expand and contract enough to lift pavers 2 to 3 inches if the sub-base wasn’t compacted to 95% before the addition went in. This is the most common failure we correct on 10- to 15-year-old paver surfaces adjacent to newer construction.
- Water pooling against the addition wall. Cambridge pavers pitch at 1/4 inch per foot when installed correctly. If the grade got disturbed during the addition, water collects at the wall line and wicks into stucco or framing. You’ll see efflorescence, a white chalky film, on the pavers first.
- Mismatched dye lots where new pavers were patched in. Someone added pavers to extend a patio, but the color is off. It looks worse at 5 p.m. in Orange County light than at noon. The fix is either sourcing the correct lot or reworking the seam pattern so the transition reads as intentional.
- Spalling or flaking near the edges. Cambridge pavers with ArmorTec hold up well, but repeated freeze-thaw cycles aren’t the only threat here. Salt air in Huntington Beach, Seal Beach, and Costa Mesa accelerates surface wear on pavers within two miles of the coast. You’ll see the top layer flake off in thin shells.
Replacement Cost & What’s Included
For a Cambridge Paver addition or ADU project in Orange County, expect $45,000 to $130,000 for the full build. That range covers a permitted 400-square-foot addition at the low end up to a full 1,200-square-foot ADU with paver hardscaping, utility trenching, and finish work at the high end. Paver-specific tie-ins and resurfacing, done as part of the project, run $15 to $35 per square foot installed, which includes removal of the failed area, recompaction of the sub-base, new bedding sand, and edge restraints.
The range moves on four things: foundation type (raised floor costs more than slab-on-grade in most OC lots), utility distance (sewer and electrical runs to an ADU can add $8,000 to $20,000), paver area, and whether the existing hardscape needs structural correction or just cosmetic matching. Every Cambridge Paver job we quote includes a written line-item price before any work starts. No numbers move at the door. That’s The Garrison Standard, and it’s been ours since 2004.
All completed work carries the 365-Day Done Right Promise: if anything fails within a full year, Bradford Remodeling returns and corrects it at no charge. The written guarantee is in your hand at close-out, with the scope documented and the site clean.

You can safely check the date codes on your existing Cambridge pavers, photograph the failure area, and mark where water pools after rain. That’s useful reconnaissance, and it saves time when we walk the site. What you should not do is start pulling pavers along a foundation edge without understanding what’s underneath. If a drain line or conduit runs under the failed area, and you pry up pavers with a bar, you can crack a waste line and turn a $3,000 paver repair into a $12,000 excavation.
There’s also a structural honesty issue here: additions and ADUs in Orange County require permits. We pull them. We’ve seen enough unpermitted sunrooms and garage conversions in Santa Ana and Garden Grove to know exactly how they fail, and paver displacement is often the first visible symptom of a foundation that was never engineered. If you’re tying Cambridge pavers into a permitted addition, call (562) 262-2907 and let Curtis Lane walk the property before you touch anything.

FAQs
Cambridge Pavers with ArmorTec typically last 25 to 40 years in Orange County when installed on a properly compacted sub-base. Coastal exposure in places like Newport Beach and Laguna Beach can shorten that to 20 to 30 years due to salt air and UV. The paver itself rarely fails; the sub-base and edge restraints go first, usually within 10 to 15 years if shortcuts were taken.
Yes, most paver failures are repairable. Edge separation, local heaving, and spot spalling can be addressed by lifting the affected area, recompacting the sub-base, reinstalling edge restraints, and relaying the pavers. Full replacement only makes sense when the pavers themselves are cracked through, or when the dye lot is discontinued and a color-matched repair isn’t achievable. Call (562) 262-2907 for an honest read on which one applies to your site.
A typical Cambridge Paver tie-in around a new addition takes 3 to 7 working days, including excavation, sub-base correction, paver installation, and edge restraint work. Larger ADU sites with full driveway or patio replacement can run 2 to 3 weeks. We give you a written schedule with the estimate, and we hit it.
We stock common Cambridge Ledgestone and RoundTable sizes in our Orange County yard, along with edge restraints, bedding sand, and jointing compound. For color-matched OEM pavers from a specific production run, we order directly with the date code you provide and have them on site within 5 to 10 business days. Estimates are free.
