Cambridge Pavers Home Additions & ADU: The Miami Owner’s Guide
If you’re planning a home addition or ADU in Miami with Cambridge Pavers as your hardscape, you’re looking at an installed cost of $53,100 to $153,400 depending on square footage, foundation work, and how much paver footage gets tied into the build. We install Cambridge Pavers-compatible additions and ADUs across Miami, and we’re honest about one thing: the paver brand matters less than the prep and sub-base work underneath it. When an addition fails, Miami homeowners usually find out through three symptoms: pavers sinking around the new foundation line, water pooling against the addition’s exterior, or cracking where the old slab meets the new paver field. That last one is the most common call we get, and it’s usually a compaction issue from the original paver install, not a defect in the Cambridge Pavers product itself.
We stock Cambridge Pavers-compatible edge restraint, bedding sand, jointing compound, and full pallets of Cambridge Pavers in the most common Miami blends. Sawyer Remodel Miami is an independent contractor, not affiliated with Cambridge Pavers, which means we tell you what works on paper and what actually holds up in Miami’s heat and hurricane-season rain. Call (850) 801-8046 for a free estimate on your addition or ADU, pavers included.
Which Cambridge Pavers Models This Applies To
Cambridge Pavers runs a few distinct product lines, and the wrong one under an addition’s foot traffic will show its limits within two years. For home additions and ADUs in Miami, the key is thickness and PSI rating. Cambridge’s Cambridge System 3000 and Cambridge System 6000 pavers are the two we spec most often for addition aprons, walkways, and patio areas. The 3000 series runs 60mm thick, which is fine for pedestrian traffic and light patio furniture. The 6000 series runs 80mm thick and gets spec’d when we know the addition will see delivery carts, grills rolled across it, or a golf cart path.
Here’s the gotcha most Miami homeowners don’t know: Cambridge Pavers manufactures in multiple regional plants, and dye lots shift between production runs. If you’re extending an existing paver field that’s more than three or four years old, an exact color match is unlikely. We handle this by blending new pavers with the old field edge-to-edge rather than patching a block in the middle, which makes the transition far less noticeable under Miami’s harsh sun. OEM Cambridge Pavers cost about 15 to 20 percent more than quality aftermarket equivalents, but for additions where the paver field is visually front-and-center, we recommend staying OEM for color consistency within a fresh pallet.
To identify what you have, flip a paver over. Cambridge stamps the series number on the underside of most 3000 and 6000 series units. If the stamp is worn off, measure the thickness with a tape measure: 60mm means 3000 series, 80mm means 6000 series.

Signs Your Cambridge Pavers Home Additions & ADU Is Failing
- Pavers sinking or dipping near the addition’s foundation line. This is almost always a sub-base failure. Miami’s sandy soil and our wet-dry expansion cycles loosen improperly compacted base rock. The pavers follow the soil downhill. If you catch it early, we can lift and re-set the affected area without touching the addition itself.
- Water pooling against the addition wall after rain. A properly graded paver field slopes away from the structure at about 1/8 inch per foot. When it doesn’t, water sits against the slab and eventually finds its way under the door threshold or into the wall. We see this most often on additions where the paver contractor graded toward an existing drain that got covered during construction.
- Cracked pavers along the walkway or patio edge. Edge restraint is the first thing to fail on Miami paver installs. When the plastic or aluminum edge loosens, pavers slide outward and crack under weight. This is a repair, not a replacement, as long as the field itself hasn’t shifted.
- Joint sand washing out after every rain. Miami’s downpours are brutal on polymeric sand. If you’re seeing channels between pavers after a storm, the sand has failed, and weeds and ants are next. We re-sand and re-seal as part of any paver remediation tied to an addition.
- Heaving or an uneven line where the addition meets the paver field. This happens when two different installers did two different compaction jobs at two different times. The addition’s concrete settles on one schedule, the paver field on another. We reset the transition with a proper expansion joint and a new edge course.

AfterReplacement Cost & What’s Included
A full home addition or ADU build with Cambridge Pavers hardscape in Miami ranges from $53,100 to $153,400. That’s the all-in number: design, permits, foundation, framing, roofing, mechanical, finishes, and the paver work. If you’re only replacing or extending the paver portion of an existing addition, you’re looking at paver installation rates that run $4,130 to $12,980 for a patio-sized area, and $8,260 to $21,240 for a full driveway-length paver field.
What drives the range? Square footage, foundation type (slab-on-grade versus raised, and Miami’s flood-zone requirements can force elevation changes), kitchen or bath finish level, and how much paver footage ties into the structure. On every job we write a line-item price before work starts. That means the paver cost, the base rock, the sand, the labor, the permit fees, and the dumpster. You see the number. You approve the number. The invoice matches the number. That’s The Relay Visibility Guarantee, and it’s the only way we work.
Every addition and ADU we build carries our 365-Day Done Right Promise. If something isn’t done right within a year of completion, we make it right, in writing, no argument.
DIY or Call Us?
There are two things you can safely check yourself before calling. First, look at the grade: does the paver surface slope away from your addition, or is water running toward the wall? Second, check the edge restraint. If you can see the plastic or aluminum edge poking out anywhere along the perimeter, the field is starting to unlock. That’s your early warning.
Beyond that, this isn’t a weekend fix. Lifting pavers, re-compacting the base, and re-setting a field that ties into an addition’s foundation takes a plate compactor, proper base rock, and an understanding of how Miami’s soil behaves under wet load. We’ve pulled up enough DIY paver patches to know the pattern: it looks fine for four months, then the corner drops and the homeowner calls us anyway, now with twice the material problem. Call (850) 801-8046 and we’ll come out, look at what’s moving, and give you a written price for exactly what needs to happen. The estimate is free, and so is the second visit if our repair ever fails.
FAQs
A properly installed Cambridge Pavers field in Miami lasts 25 to 40 years, but the sub-base underneath it may need re-compaction every 10 to 15 years because of our soil’s wet-dry cycles. The pavers themselves are dense and weather-resistant. What fails first is almost never the paver; it’s the base work or edge restraint. Call (850) 801-8046 and we’ll inspect yours for free.
Yes, in most cases. If the pavers themselves are intact, we lift the affected area, re-compact the base, add fresh bedding sand, and re-set the same pavers. Full replacement of the paver field only makes sense when the units are cracked or the pattern is discontinued. A repair typically runs a fraction of a full paver install and we’ll give you a written line-item price either way.
A full addition or ADU in Miami runs 4 to 10 months depending on permitting, foundation work, and finish level. The paver portion, if it’s a standalone repair or extension, typically takes 2 to 5 days once materials are on site. We give you a schedule in writing before work starts, and photo updates throughout, so you’re not guessing where things stand.
We keep the most common Cambridge Pavers blends and edge restraint on our truck for repair work, and we order full pallets directly for additions and ADUs. If you need an exact color match for an existing field, we’ll bring samples to your property before you commit to a pallet. Call (850) 801-8046 and we’ll check what’s available in your specific blend.
