Cambridge Pavers Home Additions & ADU: The Los Angeles Owner’s Guide
Cambridge Pavers home additions and ADU projects in Los Angeles typically run $53,100 to $153,400 installed, depending on square footage, foundation work, and whether you’re building a ground-up ADU or tying into the existing structure. Mason Remodeling works with Cambridge Pavers-compatible hardscape and structural specifications on these projects, and we’ll deliver a written price before any work starts. Most owners call us after they’ve noticed cracking in an existing paver patio or walkway connected to the house, or when they’re planning an ADU and realize the existing paver hardscape won’t survive the construction traffic.
Here’s the reality with Cambridge Pavers in Los Angeles: the pavers themselves are dense and well-made, but the base underneath them is what fails first. We see it constantly in neighborhoods like Sylmar, Sherman Oaks, and Woodland Hills. Clay-heavy soil, heat expansion, and years of irrigation overspray break down the bedding sand and compacted base. The pavers shift, crack, or sink. If you’re adding square footage or building an ADU, that compromised base means the new hardscape won’t sit level either. Fix the base, match the pavers, and the addition sits on something that lasts.
Key Takeaways
- Installed home addition and ADU projects involving Cambridge Pavers hardscape run $53,100 to $153,400 in Los Angeles.
- The paver base fails before the paver does in LA’s clay soil and heat.
- Mason Remodeling is an independent contractor, not a Cambridge Pavers dealer or affiliate.
- Every project gets a written price before the first tool is unpacked, and every crew member arrives with a photo ID badge you can verify at the door.
Which Cambridge Pavers Models This Applies To
Cambridge Pavers manufactures several lines that end up in Los Angeles hardscape projects, and the compatibility question matters more than most owners expect. The Maytrx and Ledgestone lines are common for patios and walkways tied to home additions. The RoundTable and Olde English collections show up on driveways and pool decks. Here’s the gotcha: Cambridge Pavers changes color blends and surface textures between production runs, so a paver you bought five years ago may not be available as an exact match today. Even the same named color can shift slightly between batches.
That’s why we photograph and measure every existing paver before quoting a home addition or ADU project. We check the size, thickness, edge profile, and color blend. Most Cambridge Pavers in residential use are 60mm or 80mm thick, but some older installations used 45mm units that won’t carry construction traffic. If we’re tying new paver work into an existing patio, we’ll tell you honestly whether a seamless match is possible or whether a deliberate design break looks better than a near-miss color match. For pavers we can’t match, we look at OEM spec first, then quality aftermarket equivalents that meet the same load rating.

Signs Your Cambridge Pavers Home Additions & ADU Is Failing
- Pavers sinking in a low spot near the foundation. This usually means the base layer has eroded or settled. In Los Angeles, it’s often water from irrigation or poor drainage working its way under the edge of the hardscape. If you’re building an addition, that low spot will only get worse under construction traffic.
- Cracks running across multiple pavers in a straight line. One cracked paver is a material flaw. A line of cracked pavers is a base failure. The subgrade under that strip is shifting, and the pavers are absorbing the movement. Adding an ADU next to that area will accelerate it.
- Pavers rocking or wobbling when you step on them. That’s bedding sand that has washed out or compacted unevenly. Over time the paver edges chip against each other and the surface stops draining properly.
- Weeds or ants pushing up between pavers. Joint sand has failed. Water gets in, the base softens, and biological material takes root. It starts as a cosmetic issue and becomes structural.
- Water pooling on the surface after rain. Cambridge pavers are designed to shed water when the base is pitched correctly. Pooling means the pitch is gone, the base has shifted, and the water is now working against your foundation instead of away from it.

AfterReplacement Cost & What’s Included
For Los Angeles home addition and ADU projects that involve Cambridge Pavers hardscape work, plan on $53,100 to $153,400 installed. The spread comes down to whether we’re repairing an existing paver field before building, installing new pavers alongside an addition, or handling the full hardscape for a ground-up ADU. At the lower end, you’re looking at base repair and selective paver replacement. At the upper end, you’re getting full excavation, new base, new pavers, drainage, and tying the hardscape into the new structure’s foundation line.
Every quote includes materials, labor, haul-away, base preparation, and the written guarantee. You’ll see the parts cost, the labor cost, and the scope in writing before you sign anything. The 365-Day Done Right Promise applies: if the work is not right within a year of completion, we make it right at no cost to you. No surprise invoices, no verbal estimates that grow on the final bill.
DIY or Call Us?
If you’re troubleshooting an existing Cambridge Pavers surface, there are a few things you can safely check before calling: look for pooling water after rain, walk the perimeter to spot low edges, and note any pavers that rock underfoot. That information helps us quote faster. What we don’t recommend is pulling up pavers yourself. Once you disturb the bedding sand and expose the base, water gets in, and a $2,000 repair becomes a $15,000 re-excavation. Same rule applies if you’re planning an addition: don’t let a landscaper or handyman run a compactor anywhere near existing pavers without knowing what’s underneath. We’ve seen too many good patios ruined by someone who didn’t know the base was already failing.

FAQs
In Los Angeles, Cambridge Pavers themselves can last 25 to 40 years, but the base underneath them typically needs attention every 10 to 15 years due to clay soil movement, irrigation overspray, and heat cycling. The paver rarely fails first; the base does. Call (803) 680-2547 and we’ll assess yours before you spend money guessing.
Yes, in many cases we can lift, clean, and re-lay existing Cambridge Pavers if the base is still structurally sound and the pavers aren’t cracked through. If the base has failed or the pavers are spalled from water damage, replacement is the honest answer. We’ll show you the evidence either way, and the estimate is free.
A hardscape repair tied to a home addition usually takes 3 to 7 days, while a full ADU with paver hardscape can run 8 to 16 weeks depending on permitting and foundation scope in Los Angeles. We’ll put the schedule in writing with the price, and we’ll tell you upfront if city permitting adds time.
We match and order Cambridge Pavers per project so you get the correct color blend, thickness, and edge profile rather than whatever happens to be on a shelf. For urgent repairs we keep common base materials and a limited selection of paver profiles on the truck. Call (803) 680-2547 and we’ll tell you what’s available for your job.
Mason Remodeling also works with other specification-grade brands on these projects, including KraftMaid, Cambria, and Silestone for interior finishes that tie into your new space. Know who’s coming, know what it costs, know it’s backed up – everything else is just noise.
