Cambridge Pavers Home Additions & ADU: The Los Angeles Owner’s Guide
If you already have Cambridge Pavers on your property and you’re planning a home addition or an ADU in Los Angeles, the pavers you’ve got aren’t just landscaping, they’re a match line for the whole project. A Cambridge Paver-compatible home addition or ADU typically runs $53,100 – $153,400 installed in Los Angeles, depending on square footage, foundation work, and how much paving needs to be cut, salvaged, or extended. Most owners discover the paving angle the hard way: the new foundation line doesn’t meet the old patio cleanly, and suddenly you’re looking at a 3-foot strip of mismatched concrete where your Cambridge pavers used to be.
We’re Penhallow Remodeling Los Angeles, and we handle Cambridge Pavers integration on additions and ADUs as a regular part of the job. That means we don’t just frame walls and pull permits. We match the paver pattern, replace cracked units with the right series and color, and make sure the transition from new structure to old hardscape looks like it was planned from day one. Trevor Nash, our owner, will tell you plainly what the paving piece costs before we ever put a shovel in the ground. Give you a number first, then pick up the tools.
Which Cambridge Pavers Models This Applies To
Cambridge Pavers runs several paver lines across Los Angeles driveways, patios, and pool decks, and not all of them mix well. The most common series we see on additions and ADUs are the Ledgestone, Maytrx, RoundTable, and Pavingstone Collection lines. Here’s the compatibility gotcha most homeowners don’t know: Cambridge changes mold dimensions between production runs, and a paver bought in 2017 is often not a true dimensional match for the same-named series bought this year. A 3/8-inch difference per unit doesn’t sound like much until you’re laying forty pavers in a row and the pattern drifts by more than a foot.
On the OEM-versus-aftermarket question: Cambridge Pavers are manufactured to tight specs, but they’re not like appliance parts where aftermarket means risky. Quality aftermarket pavers from brands like Belgard and Unilock can work if you’re replacing an entire section rather than patching a few units. If you’re weaving into an existing Cambridge field, you want genuine Cambridge product with the same series name and, ideally, the same lot code. We photograph the back of one paver before ordering so the match is based on measurements, not memory. That’s saved more than a few Los Angeles homeowners from a patch that looks like a scar.

Signs Your Cambridge Pavers Home Additions & ADU Is Failing
- The pavers next to the old foundation are sinking or tilting. This usually means the base material under the original installation wasn’t compacted deep enough for the new drainage pattern created by the addition. Water is now pooling where it didn’t before, and the base is washing out.
- Cracks running in a straight line across multiple pavers. That’s not a paver failure; that’s the soil underneath settling unevenly where the new foundation trench was backfilled. The pavers are just following the ground down.
- Color mismatch at the transition line between old paving and new. Cambridge Pavers fade differently depending on sun exposure. A south-facing Los Angeles patio will be noticeably lighter than a north-facing strip after five years. New pavers next to old look wrong unless the rest of the area is reset or blended.
- Weeds or ants pushing up between pavers near the new structure. When the original paver joint sand is disturbed during construction and not replaced with polymeric sand, weeds find the gap within a season. Ants love those joints too.
- Water pooling against the new stem wall after rain. The addition changed the grade, and now runoff sits against the foundation instead of draining away. This will eventually compromise both the paver base and the structure’s moisture protection.

AfterReplacement Cost & What’s Included
The full home addition or ADU with Cambridge Paver integration runs $53,100 – $153,400 in Los Angeles. Where you land in that range depends on square footage, whether the addition ties into existing plumbing and electrical or needs new service, foundation type, and how much paver work the site demands. At the lower end, a modest bump-out with a small paver repair and reset might stay near $53,000. At the upper end, a full ADU with a kitchenette, bathroom, and 800 square feet of new Cambridge paving to match the old is going to climb toward $150,000 and beyond.
What’s included: we write the price before work starts, and that number includes permits, materials, labor, paver matching and reset, and the written guarantee. The 365-Day Done Right Promise covers the workmanship on the project for a full year. If a paver settles or a seam opens up inside that year, we come back and fix it at no charge. No re-inspection fee, no “that’s normal settling” conversation. Just done right. For reference, we also work with KraftMaid and Cambria on the interior side of additions and ADUs, and Silestone when the project calls for quartz surfaces.
DIY or Call Us?
There are a few things you can check yourself before you pick up a phone. Walk the line where the new work meets the old pavers and look for sinking or separation. Check whether water drains away from the foundation or toward it after a rain. If a few pavers are cracked, you can lift them with a screwdriver and look at the base underneath. If the base is solid and dry, that’s a simple unit replacement. If the base is wet, muddy, or has ants tunneling through it, the problem is underneath, and resetting pavers on a bad base means doing the job twice.
Where DIY goes wrong is the base work and the match. Compacting a paver base properly requires a plate compactor and knowing how many inches of crushed rock belong under the sand for your soil type and drainage pattern. Most Los Angeles yards sit on a mix of clay and fill that shifts with the seasons. If the base wasn’t right the first time, redoing just the pavers gives you a pretty floor over a failing foundation. That’s the kind of repair that cracks again six weeks later, which is exactly what we don’t want for you. Call (213) 277-6578 and we’ll give you a written price and a real answer about what’s actually going on under your pavers.
FAQs
Cambridge Pavers typically last 25 – 40 years in Los Angeles when installed on a properly compacted base, but the base itself may need rework after 15 – 20 years, especially where soil expands and contracts through wet and dry seasons. The pavers rarely fail first; the ground under them does. Call (213) 277-6578 if your pavers are shifting near a foundation line and we’ll tell you what you’re actually looking at.
Yes, individual cracked pavers can be swapped with matching units, and sunken sections can often be lifted, re-based, and reset without buying new material, though a true repair means fixing the base underneath, not just replacing the surface. If the base is intact, repair is straightforward and costs a fraction of replacement. Call (213) 277-6578 and we’ll give you a written price for the repair before any work starts.
A small paver reset around a new foundation usually takes one to two days, while a full Cambridge Paver reinstallation across a patio or driveway can run three to five days depending on square footage and base conditions. We’ll give you a defined arrival window and a written schedule before we start. Call (213) 277-6578 to get a time estimate for your specific project.
We keep a limited stock of common Cambridge Paver series units on hand for quick repairs, and we order specific colors and sizes for larger additions and ADU projects, which typically takes a few days to a week in Los Angeles. We’ll match by series name and physical measurement, not just the color name. Call (213) 277-6578 and we’ll check stock and lead time for your specific paver line.
