Cambridge Pavers Home Additions & ADU: The Los Angeles Owner’s Guide
If you have Cambridge Pavers on your driveway, patio, or walkway and you’re planning a home addition or ADU in Los Angeles, the pavers themselves are almost never the problem. The issue is what happens to them during excavation, foundation work, and material staging. A full home addition or ADU project in Los Angeles typically runs $53,100 to $153,400, and a meaningful portion of that cost goes toward protecting or resetting existing hardscape like Cambridge Pavers before and after construction. Most owners discover this the hard way: the concrete truck cracks a corner of the paver driveway, or the skid steer’s treads leave permanent scuff marks across the patio. The good news is that Cambridge Pavers are modular, which means damaged sections can usually be removed, the base re-compacted, and the same (or matching) pavers reset without replacing the whole surface. At Elmstead Remodeling, we handle this as part of the project scope, not as an afterthought.
Which Cambridge Pavers Models This Applies To
Cambridge Pavers manufactures several paver lines commonly seen across Los Angeles driveways and patios: the MaytRx series, Ledgestone, RoundTable, and the permeable Aqua-Bric line. The compatibility issue most owners miss is that Cambridge changed the dimensional tolerances on some MaytRx shapes about eight years ago, so a paver purchased yesterday will not always lock cleanly against one from the original 2012 run. If your pavers were installed before 2017 and you need a patch, we bring the original paver or a photo with a ruler to our supplier and match the actual measured face dimensions rather than trusting the series name alone. For OEM versus aftermarket, the honest answer is that aftermarket pavers that mimic Cambridge shapes look close from a distance but are never a true color or texture match, especially on Los Angeles jobs where UV exposure has faded the original pavers for a decade or more. When the job involves a home addition or ADU, we recommend buying genuine Cambridge Pavers for any visible patch areas and reserving aftermarket only for sections that will be covered by the new structure.

Signs Your Cambridge Pavers Home Additions & ADU Is Failing
Here is what we find when we walk a Los Angeles property before an addition or ADU project starts:
- Settled pavers near the proposed foundation line. This usually means the base material was not compacted deeply enough for the load it has been carrying. Once excavation starts nearby, that settlement accelerates fast.
- Sinking or heaving around tree roots. Los Angeles ficus, magnolia, and camphor trees push roots through paver bases looking for water. When an addition shades a root zone or changes drainage, the pavers shift within the first year.
- Edge pavers separating from the border course. The edge restraint was likely plastic or timber that has failed. Without that border locked in, the entire field begins to drift outward under vehicle or foot traffic.
- Cracked pavers near the old driveway approach. This is a load issue: a vehicle turning repeatedly over a section that was not designed for point loading. Cambridge Pavers hold up, but the base below them can fail from years of the same tire path.
- Efflorescence or surface wear that has changed the paver’s face texture. This is less structural and more cosmetic, but it tells us how the pavers have been treated over the years. If the surface is heavily worn, patching with new pavers will look patchy unless we address the whole visual field.

AfterReplacement Cost & What’s Included
When pavers are part of a home addition or ADU project in Los Angeles, the cost depends on scope: a full driveway paver replacement runs $8,260 to $21,240, while a smaller paver patio sits in the $4,130 to $12,980 range. The paver work is often a separate line item from the addition itself, which is why our written scope breaks out hardscape protection and reset costs before any work begins. What drives the range: how many pavers must be removed and reset, whether the existing base can be re-compacted or must be excavated to 8 inches and rebuilt, whether we are matching UV-faded pavers, and how much access the construction equipment has. Parts and labor are separated on the written price, so you see exactly what the Cambridge Pavers material costs versus the crew time. The reset and replacement work falls under the same 365-Day Done Right Promise as every other Elmstead project. If a reset paver settles within the year, we come back and make it right.
Below are the project price ranges we quote across Los Angeles:
- Home Addition: $53,100 – $153,400
- ADU Construction: $106,200 – $259,600
- Garage Conversion: $35,400 – $94,400
- Paver Driveway Installation: $8,260 – $21,240
- Paver Patio Installation: $4,130 – $12,980
- Driveway Replacement: $5,900 – $16,520
DIY or Call Us?
If you are dealing with a few loose or cracked Cambridge Pavers and the base underneath is still tight, you can often lift and reset them yourself with a rubber mallet and some paver sand. What you should not do is attempt to remove or reset a large paver field that sits under or beside an active construction zone. The danger is not the paver; it is what happens when a paver field is no longer interlocking while heavy equipment moves across it. A cracked paver at the edge of an excavation trench can shift sideways under a loaded wheelbarrow, and now you have a twisted ankle or a dropped load. For any paver work tied to a home addition or ADU, call us at (949) 850-9896. We walk the site, mark the pavers that need to be lifted, photograph the layout so every paver goes back in the same position, and write the scope before any work starts.
FAQs
How long do Cambridge Pavers last in Los Angeles?
Cambridge Pavers themselves will last 30 to 50 years in Los Angeles weather; what fails first is the paver base, which typically needs re-compaction or replacement at the 15 to 20 year mark. Our reset work includes base evaluation as a standard part of the scope, not an add-on.
Can you repair just the damaged section instead of replacing the whole paver field?
Yes, and that is normally the first approach we take. We remove the affected pavers, rebuild the base in that section, and re-set the pavers to match the surrounding field. The challenge is color matching pavers that have been through 10 or 20 Los Angeles summers, so expect the patched area to blend gradually over the first year.
How long does a paver reset take during a home addition or ADU project?
A standard driveway paver reset runs one to two days once the construction equipment is off the field. A larger paver patio reset near an ADU foundation typically takes two to three days, including base re-compaction and the final sand sweep.
Do you stock Cambridge Pavers on the truck?
We do not stock full Cambridge Pavers pallets on the truck because the series and color range is too wide, but we keep paver sand, edge restraints, and base material on board for immediate repairs. For the pavers themselves, we pull exact measurements on the first visit and bring the correct product on the day the work is scheduled.
