Cambridge Pavers Home Additions & ADU: The Pasadena Owner’s Guide
Home additions and ADUs built around Cambridge Pavers products in Pasadena typically run $45,000 to $130,000 installed, depending on square footage, foundation work, and whether you’re tying into existing plumbing and electrical. We’re Sawyer Remodel Pasadena, an independent contractor working with Cambridge Pavers materials on additions and ADUs across Pasadena – not affiliated with Cambridge Pavers, but deeply familiar with how their paver systems, wall blocks, and edge restraints behave in Southern California soil. Most owners call us after they notice a failure: a settling corner, a cracked cap on a seat wall, a paver field that’s shifted where the new foundation meets old concrete, or drainage that pools against the addition’s stem wall after the first hard rain.
Which Cambridge Pavers Models This Applies To
Cambridge Pavers splits their catalog into a few families that matter for additions and ADUs. The Maytrx and Ledgestone lines are the most common we see on Pasadena jobs for walls and columns, and the RoundTable and Sherwood paver lines go under patios and walkways that connect to the new structure. Here’s the compatibility gotcha most homeowners don’t know: Cambridge color lots vary year to year, and a paver bought in 2021 won’t match a paver ordered in 2025, even with the same color name. If we’re extending an existing Cambridge patio as part of your addition, we pull a sample from your current field and get the closest current-lot match before ordering. For wall block identification, flip a cap or block and look for the Cambridge stamp on the underside – that stamp tells us the series and whether it’s a current production run or a discontinued shape that needs a custom cut. Aftermarket equivalents exist for some shapes, but Cambridge’s edge profiles and joint spacing are proprietary enough that we spec OEM units on visible work.

Signs Your Cambridge Pavers Home Addition or ADU Is Failing
- Paver field sinking near the new foundation. Pasadena’s clay-heavy soil expands and contracts with moisture. If the base wasn’t compacted to 95% or the subgrade wasn’t stabilized, you’ll see a dip within two seasons. That’s a base failure, not a paver failure, and it means pulling the field and redoing the layers.
- Separating edge restraints. The plastic or aluminum edging that locks pavers in place shifts when a new slab meets old grade. Once an edge lets go, the pavers walk outward and the pattern opens up. You’ll see a widening gap at the perimeter first.
- Cracked wall caps or split block faces. Cambridge wall systems are strong, but a cap that wasn’t adhered with a flexible construction adhesive will pop when the wall settles slightly. Hairline cracks in faces usually mean lateral pressure from drainage problems behind the wall.
- Water pooling against the addition’s stem wall. In Pasadena’s winter rains, a paver patio with insufficient slope (needs about 1/8 inch per foot) sends water into the foundation line instead of away. You’ll see a dark waterline at the base of the stucco or siding.
- Joint sand washing out after rains. Polymeric sand needs a solid edge and proper paver surface prep to set. If you see little channels forming between pavers after storms, the sand didn’t cure correctly or the base is moving, and the pavers will start shifting shortly after.

AfterReplacement Cost & What’s Included
For Pasadena homeowners, a paver patio or walkway that ties into a home addition or ADU typically runs $3,500 to $11,000 just for the hardscape portion. A full home addition on the Cambridge systems we work with lands between $45,000 and $130,000 total, and an ADU goes higher, into the $90,000 to $220,000 range. What drives the spread on additions and ADUs: whether you need new footings and a stem wall ($8,000 to $25,000 depending on the add-on size), whether the existing Cambridge field needs partial or full replacement, and whether your addition triggers Pasadena’s solar-ready and Title 24 requirements. Our written price comes before any work starts, and it includes all base material, compaction, edge restraint replacement, joint sand, and the labor to set the pavers back. If we touch your Cambridge field as part of the addition and it isn’t done right, the 365-Day Done Right Promise covers it: we make it right, in writing, no argument. Call (626) 657-5396 and we’ll give you a line-item quote.
DIY or Call Us?
You can safely reset a single shifted paver if you can lift it by hand and the base underneath is still solid. That’s about it. Anything beyond that, and you’re into base compaction, re-sloping, and matching Cambridge’s current color lots, which is where DIY jobs go wrong. One Pasadena homeowner we worked with near Bungalow Heaven tried patching a settled corner themselves, picked up pavers, laid them back on loose sand, and watched the whole section sink again in March. The work tells you everything. You just have to know how to listen to it. If the failure is deeper than one paver, call (626) 657-5396 for a free estimate. We’ll tell you if the base is shot before we quote anything.
FAQs
Twenty-five to forty years is a realistic lifespan for Cambridge pavers in Pasadena’s climate, assuming the base was compacted properly and the joints were maintained. The pavers themselves are high-strength concrete, and they’ll handle the heat and UV fine; what shortens the lifespan is base movement and edge failure, not the units themselves. Call (626) 657-5396 if you want us to look at yours.
A cracked paver can usually be cut out and swapped, but a sunken field or failing edge restraint can’t be repaired without redoing the base. If the issue is one or two cracked units, we can often match the current Cambridge color lot; if the whole section is moving, the repair is in the layers underneath. Call (626) 657-5396 and we’ll tell you which one you have.
A single paver swap takes under an hour. A wall cap reset takes a day including adhesive cure time. A full paver field that needs base recompaction is two to three days for a typical Pasadena rear patio. We’ll put the timeframe in your written estimate before any work starts, so there’s no mystery.
We don’t stock Cambridge Pavers units on the truck, because color lots change so often and carrying the wrong lot means a visible patch job. We identify your series and color lot first, then order the exact match from Cambridge’s current Pasadena distributor. For accessory parts like edge restraints and polymeric sand, we carry several options and can usually start the repair same week.
