Cambridge Pavers Home Additions & ADU: The Escondido Owner’s Guide
We stock and install Cambridge Pavers-compatible hardscape systems for home additions and ADU projects in Escondido, with typical installed pricing from $45,000 to $130,000 for additions and $90,000 to $220,000 for detached ADUs. Most Cambridge Pavers patio, walkway, and driveway components integrate with our standard addition and ADU foundations without special ordering. Call (858) 683-6538 to schedule your free estimate.
Most owners discover their Cambridge Pavers surface is failing when they see efflorescence whitening, settling that creates trip hazards, or joint sand washing out after Escondido’s seasonal Santa Ana wind and rain cycles. The paver itself is rarely the problem; it’s usually the base preparation, edge restraint, or drainage layer beneath it that has shifted on our local decomposed granite and clay soils.
Which Cambridge Pavers Models This Applies To
Cambridge Pavers produces several product lines we regularly integrate into Escondido home additions and ADUs. The ArmorTec series, with its through-body color and surface-hardening process, is the most common choice for outdoor living spaces tied to additions because the color remains consistent even if surface wear occurs. The Olde English line, thicker at 80mm versus the standard 60mm, is specified when the paver surface will bear vehicle loads on an ADU driveway or shared courtyard.
To identify your existing Cambridge Pavers installation, look for the manufacturing stamp on the paver edge, which includes the production run date and series code. Measure the paver thickness with a tape measure; 60mm pavers are roughly 2.36 inches, while 80mm pavers run about 3.15 inches. The joint width matters too: Cambridge recommends 1/16 to 3/16 inch for their proprietary polymeric sand systems to activate correctly.
We are an independent service provider, not affiliated with Cambridge Pavers. For warranty-matched replacement of failed pavers still under Cambridge’s limited lifetime warranty, we source direct from authorized distributors in San Diego County. For out-of-warranty repairs or color-matched expansions, we use equivalent-spec pavers from Belgard or Techo-Bloc, both vetted brands in our fifty-plus supplier list, which keeps the written quote honest rather than inflated by single-source pricing.
Signs Your Cambridge Pavers Home Additions & ADU Is Failing

- Efflorescence that returns after cleaning. White mineral deposits on the paver surface indicate moisture is moving through the base material and carrying soluble salts upward. In Escondido’s inland climate with low average humidity but intense winter rain events, this usually means the bedding sand layer was contaminated with clay or the vapor barrier beneath the base was omitted or punctured during original installation.
- Sinking or tilting pavers in isolated patches. When a section drops below grade while adjacent areas remain level, the compacted aggregate base has washed out or decomposed. We see this frequently near downspout outlets on Escondido additions where roof drainage was directed onto the paver surface without a proper channel or dry well.
- Joint sand washing out repeatedly. Polymeric sand that fails to harden and stays loose, or washes away within a season, typically means the joint was too wide at installation, the sand was applied to a damp surface, or the activation water was applied unevenly. Cambridge’s polymeric sand requires a completely dry surface and controlled water misting to set the polymer binders.
- Edge restraints pulling away from the perimeter. The plastic or aluminum edging that holds the outer course of pavers in place is secured with long spikes into the base. When these work loose, the entire field of pavers loses lateral support and spreads outward. This accelerates rapidly on sloped sites common in Escondido’s hillside neighborhoods near Dixon Lake and the Kit Carson Park area.
- Chipping or spalling on the paver surface. ArmorTec pavers resist this well, but cheaper imported pavers or non-ArmorTec Cambridge lines can show surface degradation when subjected to de-icing salts, pressure washing at close range, or the thermal shock of Escondido’s 100-plus-degree summer days followed by rapid evening cooling.

AfterReplacement Cost & What’s Included
For Cambridge Pavers repair or replacement integrated with a home addition or ADU project in Escondido, our installed pricing ranges from $45,000 to $130,000 for additions and $90,000 to $220,000 for full detached ADUs. Within that range, the hardscape portion typically runs $7,000 to $18,000 for paver driveways and $3,500 to $11,000 for patios, with walkways and courtyards falling between.
What drives the range: base depth and compaction requirements vary with soil conditions, which we test before quoting; drainage complexity increases on sloped lots; and paver series selection affects material cost per square foot. Our quote includes removal of failed material, recompaction or replacement of the aggregate base, bedding sand, pavers, joint sand, edge restraint, and cleanup. Under Clause 1 of the Haven Standard, the price is written before anyone starts, and no change proceeds without a signed change order.
The 365-Day Done Right Promise applies: if the joint sand settles, pavers shift, or drainage fails within a year, we return and make it right. Every visit includes a documented photo record, standard, not an upgrade.
DIY or Call Us?

There’s a clear line between what an Escondido homeowner can check safely and what requires our crew.
What you can do: verify the paver series by reading the edge stamp; measure the affected area in square feet; photograph the failure pattern from multiple angles; and check whether your original installation included Cambridge’s warranty registration, which may still be active. This documentation helps us prepare an accurate quote before we arrive.
Where DIY goes wrong: removing pavers without understanding the base layer risks collapsing the entire field. Recompacting aggregate base requires a plate compactor and moisture control that most homeowners don’t have access to. Polymeric sand installation demands bone-dry conditions and precise water activation; get it wrong and you’re scraping wet sand out of joints for hours. More critically, if your addition or ADU’s paver surface ties into a retaining wall, drainage system, or structural foundation, disturbing it without knowing the load path can compromise the structure.
We carry Cambridge Pavers-compatible base materials, edge restraints, and joint sand on our trucks. For paver color matches, we sample from your existing installation and source from San Diego distributors, usually within 48 hours. Measure twice, quote once, show your work. Call (858) 683-6538 for your free estimate.
FAQs
Properly installed Cambridge Pavers should last 25 to 50 years in Escondido’s Mediterranean climate, with the ArmorTec surface warranty covering 25 years against manufacturing defects. The limiting factor is almost always the base and drainage system beneath the pavers, not the paver itself, which is why we inspect substrate conditions before quoting any repair. Call (858) 683-6538 for an exact quote on your specific installation.
Individual pavers can be lifted and reinstalled if the base is sound, which costs significantly less than full replacement. However, if the base has washed out or the bedding sand is contaminated, lifting pavers without addressing the underlying failure guarantees the problem returns within one to two rainy seasons. We provide a written assessment of whether repair or replacement is the honest recommendation for your situation.
Most paver repairs for additions and ADUs run two to five working days, depending on base reconstruction needs and weather. Polymeric sand requires 24 hours of dry curing after activation, so we schedule around Escondido’s forecast and avoid application when rain is predicted within that window. Full ADU hardscape installations with integrated drainage take one to three weeks.
We stock base materials, bedding sand, edge restraints, and polymeric joint sand on every truck. Cambridge Pavers themselves are sourced to match your existing color and series from San Diego-area distributors; we do not carry full paver inventory because color matching requires sampling from your actual installation. Most special orders arrive within 48 hours, and we coordinate delivery to arrive when the base prep is complete.
