Cambridge Pavers Home Additions & ADU: The Fort Myers Owner’s Guide
We get calls almost weekly from Fort Myers homeowners who built with Cambridge Pavers and now want to expand their living space. The big question is usually the same: can we build an addition or ADU that actually matches the existing paver work without it looking like two different houses? The answer is yes. We install Cambridge Pavers-compatible home additions and ADUs in Fort Myers, with total project costs typically ranging from $45,000 to $130,000 for an addition and $90,000 to $220,000 for a full ADU. Most owners discover the need for this not because something “failed” in the traditional sense, but because their paver patio or driveway layout suddenly needs to integrate with a new foundation, new drainage requirements, and new hardscape tie-ins that a standard addition crew won’t touch.
What makes Cambridge Pavers specifically relevant here is that their modular sizing system and color-through body construction mean you can match existing stone exactly, provided whoever’s doing the work knows how to order from the correct production run and account for Fort Myers’ high water table during site prep. A lot of addition contractors in Lee County will pour the slab and call it done, then hand you a business card for “a paver guy.” We handle the whole scope under one roof so your new living space and your hardscape don’t feel like two separate projects.
Which Cambridge Pavers Models This Applies To
Before we touch a shovel, we identify exactly which Cambridge product line you have on the ground. Cambridge runs three main residential series compatible with home additions and ADU tie-ins in our market: the Ledgestone Series (most common for Fort Myers pool decks and patios), the Roundtable Series (frequent on driveways), and the Maytrx Series (often used for larger outdoor living areas). Each uses different joint widths and base-layer requirements. The quickest way to confirm your pavers is to check the underside of a loose stone for a stamped lot code. If you saved the original install paperwork from when the patio went in, that’s even better, though in our experience about eight out of ten homeowners in Fort Myers bought the house with the pavers already there.
For the actual addition or ADU structure itself, the paver specification matters most at the foundation transition points: stoops, walkway connections, and any covered porch areas where the roofline ties into existing hardscape. We use OEM Cambridge Pavers for match-critical areas because color consistency across dye lots is precise, and the compaction tolerance is engineered for Florida’s sandy-loam base. We do stock limited Cambridge-compatible aftermarket edge restraints for minor repairs, but for a structural addition project, we only install factory product to keep the warranty intact.
Signs Your Cambridge Pavers Home Additions & ADU Is Failing
- Settling or sinking near the foundation line. This usually means the original base wasn’t compacted deep enough for Fort Myers’ soil, which shifts noticeably between wet and dry seasons. When you add the weight of a new structure, the paver transition zone gives out first.
- Water pooling at the addition’s drip edge. Cambridge Pavers are permeable to a point, but if the slab was poured without accounting for the paver runoff plane, you’ll get standing water that slowly erodes the polymeric sand joints.
- Cracking in the paver-to-structure connection. Different materials expand at different rates in Florida heat. Without a proper expansion joint between the addition’s slab and the paver field, one or both will crack within two years.
- Color fade mismatch on newer sections. Cambridge uses color-through manufacturing so the stone itself doesn’t fade, but if someone patched in a different production run without checking lot numbers, the tint is permanently off and the only fix is re-laying that section.
- Root intrusion from nearby live oaks or palms. Fort Myers has aggressive root systems. If the addition’s foundation trenching disrupted roots near the paver area, you’ll see lifting within 12 to 18 months as the tree recovers and pushes new growth.
Replacement Cost & What’s Included
For a home addition or ADU project in Fort Myers that ties into existing Cambridge Pavers, installed costs land between $45,000 and $220,000 depending on square footage and structural complexity. On the lower end, that covers a single-room bump-out with basic paver re-lay at the connection points. The upper range gets you a full detached ADU with kitchen, bath, foundation, roofing, and complete hardscape integration. What drives the price: foundation type (slab-on-grade runs less than a stem-wall in flood zones), paver square footage that needs resetting, and whether we’re tying into existing drainage or cutting new swales per Lee County code.
Every project includes the materials, labor, site prep, base compaction, joint sand, edge restraint, and a written line-item estimate so you know exactly where the money goes before we start. The work is covered by our 730-Day Done Right Promise: if it’s not done right, we make it right. We also pull permits and coordinate inspections so you’re not left holding a stop-work order six months later.
DIY or Call Us?
Here’s the honest breakdown. If you notice a few loose pavers near an existing slab edge and you’re just curious whether the base is still solid, you can lift one with a flathead screwdriver and check for washout yourself. That’s reasonable. But the moment you’re talking about tying paver work into new construction, you are dealing with foundation loads, floodplain elevations, and structural connections that fail expensively if they’re off by even an inch. We’ve fixed enough DIY addition tie-ins in Fort Myers to know the pattern: the homeowner spends a weekend on YouTube, rents a compactor, and then calls us six months later when the corner of the patio sinks two inches and channels water toward the house.

FAQs
How long do Cambridge Pavers last in Fort Myers’ climate?
Cambridge Pavers are rated for a 50-plus-year structural lifespan, but the joints and base layer in Fort Myers typically need attention every 15 to 20 years due to seasonal soil movement and tropical rainfall cycles.
Can you repair a failing paver-to-addition connection instead of replacing it?
Sometimes yes, if the issue is limited to joint sand erosion or a small localized dip. If the base is compromised or the slab has shifted, a repair just buys time, and full re-lay of the affected section is the only lasting solution. We’ll tell you which one you actually need after we look at it.
How long does a home addition or ADU project take when pavers are involved?
A straightforward addition with paver tie-in work usually runs 8 to 14 weeks in Fort Myers, depending on permitting timelines with Lee County and weather windows for the hardscape phase. ADUs add roughly 4 to 6 weeks for full utility rough-in and finish-out.
Do you stock Cambridge Pavers in Fort Myers?
We keep the most common Ledgestone and Roundtable colors on hand for immediate tie-in work, and we have direct-order access to the full Cambridge catalog with lead times typically under two weeks. If we don’t have your exact paver on the truck, Derek Hollenbeck can usually track it down faster than you’d get through a retail desk.
