Cambridge Pavers Home Additions & ADU: The Houston Owner’s Guide
A home addition or ADU using Cambridge Pavers materials around Houston typically runs $45,000 – $130,000 depending on the size of the addition, whether it includes a full bathroom or kitchenette, and how the paver work ties into the existing hardscape. We handle the full build including the Cambridge Pavers hardscape elements, and we can usually get started within two to three weeks of the signed contract. Most homeowners don’t even know they have a paver problem until the addition is already framed. You notice a hump in the walkway, a paver that shifted after the last big rain, or a section of the patio that drains toward the new foundation instead of away from it. That is usually when the photos get taken and the texts get sent from a kitchen table somewhere in Meyerland or Memorial.
Here is the straight story: Cambridge Pavers are built well. The failure usually is not the paver itself. It is what sits under it, how the base was compacted, how the drainage was routed, and whether the addition’s roofline is now dumping water onto the paver edge. If you are adding square footage in Houston, the paver work around that addition has to be planned at the same time as the foundation work, not after the drywall is up. We have fixed enough paver failures around new additions in the Energy Corridor and Katy to know the difference between a paver problem and a drainage problem, and they are not the same fix.
Key Takeaways:
- Cambridge Pavers work on additions and ADUs runs $45,000 – $130,000 in Houston, including hardscape tie-in
- Paver failure around a new addition is usually a base compaction or drainage issue, not a bad paver
- We stock Cambridge Pavers-compatible materials from our Houston suppliers, and Trevor Nash leads every estimate
- Every project gets a written price, a written arrival window, and the 365-Day Done Right Promise in writing
Which Cambridge Pavers Models This Applies To
Cambridge Pavers makes three distinct paver lines that show up regularly on Houston home additions and ADU projects: the Ledgestone series (often used for knee walls, fire pit surrounds, and stair risers), the Traditional/Paving Stone series (driveways, walkways, patios), and the RoundTable collection (pool decks and large patios). The key compatibility fact to know before you buy a single replacement paver is the thickness. Cambridge Pavers around Houston are typically installed at 60mm thickness for driveways and 45mm for patios and walkways. If you try to match a 45mm paver to a 60mm driveway field, you will have a visible height difference that will fail the first time a car rolls over it.
The manufacturer stamps a lot number and series code on the underside of most Cambridge Pavers. Before we order anything, we flip a few pavers and check the code against the existing field. Color lot variance is real with concrete pavers, and a paver from a new production run will not perfectly match a paver installed eight years ago. That fade difference matters more on a large ADU patio than a small walkway repair. We tell owners this up front: we can match the series and size exactly, but the sun-faded color will be a close match, not a perfect match. If that bothers you, we will quote a full paver replacement on that section so the new work and the old work read as one surface.
We are an independent service provider, not affiliated with Cambridge Pavers. We use their materials because they hold up in Houston’s clay-heavy soil and summer heat better than most, and because we can source them reliably from local supply houses. For the hardscape adjacent to your addition or ADU, we also work with matching brands like Belgard and Unilock when the Cambridge line does not carry the specific color or finish the original builder used.

Signs Your Cambridge Pavers Home Additions & ADU Is Failing
- Pavers sinking or pooling water near the new foundation. This usually means the base under the pavers was not compacted after the addition’s foundation work disturbed the soil. In Houston’s clay soil, especially near Meyerland where the soil moves with moisture, this gets worse after every heavy rain. Water pooling at the foundation edge is a warning sign, not a cosmetic issue.
- Gaps opening between pavers along the addition’s drip line. When the roofline of a new addition sends concentrated water onto the paver edge, the sand between joints washes out. The gap starts small, then the pavers start to rock underfoot. You will see this most often where a downspout empties onto a paver walkway.
- Edge restraint failure along walkways and driveways. Cambridge Paver fields need a plastic or concrete edge restraint to hold the outside border in place. If the edge restraint was cut during addition work, the border pavers start to drift outward, and the whole field loses tension. Once the edge is gone, the field starts moving one paver at a time.
- Cracked or chipped pavers where construction traffic crossed. During a home addition, wheelbarrows, skid steers, and dumpsters cross your existing paver surfaces. A 45mm paver installed over a patio base was never rated for that kind of point load. We see cracked pavers in straight lines from the dumpster to the addition site all the time.
- Paver color fading unevenly around the new shaded area. A new ADU casts shade on part of the paver field for most of the day. Shaded pavers hold moisture differently than sun-exposed pavers, and the color develops a visible line over two or three years. This is a cosmetic issue, but if you are already repairing a section, it is worth addressing while pavers are being pulled anyway.

AfterReplacement Cost & What’s Included
The full cost of a home addition or ADU with Cambridge Pavers hardscape work in Houston runs $45,000 – $130,000. That range is driven by the square footage of the addition, whether the space includes plumbing (a bathroom or wet bar), the roofline tie-in complexity, and how much paver repair or new paver installation is required around the build. An ADU adds more on the plumbing and foundation side than a simple bedroom addition, and the pavers around an ADU usually include a new walkway and drainage swale. Here are the realistic ranges we quote in the Houston metro:
- Home addition (paver tie-in and walkway work only): $45,000 – $130,000
- ADU construction (with paver patio and walkway): $90,000 – $220,000
- Paver patio installation (standalone, new or replacement): $3,500 – $11,000
- Paver driveway installation (standalone, new or replacement): $7,000 – $18,000
- Drainage correction at paver/foundation edge: typically $1,500 – $4,500 depending on run length and whether a French drain is needed
Every one of those numbers comes with a written line-item price before any work starts. No verbal ballpark, no change order surprises after demo. The paver portion of the work includes new or repaired base material, joint sand, edge restraint replacement if needed, and the pavers themselves. We source the base material from local Houston supply yards that know our clay soil conditions, and the pavers come direct from Cambridge Pavers distribution. The work is covered by our 365-Day Done Right Promise in writing: if the paver work fails within the guarantee period, we return and fix it at no charge. Not a prorated credit, not a service fee. We fix it.
DIY or Call Us?
There are some things worth checking yourself before you call. Walk the paver field with the hose running and watch where the water goes. Check the downspouts from the addition and see whether any of them pour directly onto the paver edge. Pull up one loose paver and look at the base underneath: if the base material is thin, wet, or mixed with Houston clay, that tells you the failure is structural, not cosmetic. That is where your useful DIY work ends. Paver replacement around an addition is not a weekend project. Getting the base recompacted, re-sloping the drainage away from the foundation, and reinstalling edge restraint correctly takes compactors, string lines, and more patience than most homeowners want to spend. And if the pavers are near a foundation wall, getting the water management wrong makes a paver problem into a foundation problem.

FAQs
Cambridge Pavers themselves typically last 25 to 40 years in Houston’s climate, but the base underneath them usually needs attention around the 10 to 15 year mark, especially in areas with clay-heavy soil like Meyerland or Bellaire. The paver on top rarely fails first; the base, the edge restraint, or the drainage is what gives out. Call (254) 527-5340 for an exact assessment of your paver conditions, and we will tell you what is actually failing and what it will cost to fix it.
Yes, in many cases a failing paver section can be lifted, the base recompacted, and the original pavers re-laid, which typically costs 40 to 60 percent less than a full replacement. The exception is when the pavers themselves are cracked from construction traffic or sun-faded to the point that a patch repair would look obvious. Call (254) 527-5340 and we will tell you honestly whether a repair or a replacement makes more sense for your specific situation.
A typical home addition takes 12 to 20 weeks from the first dig to final inspection, and the paver portion alongside it usually runs two to four weeks on its own, depending on the square footage and weather. An ADU runs longer, typically five to seven months from permits to occupancy. We give you a written schedule before we start, and if the timeline moves, we tell you why and what the new date is. If you are planning a paver project or addition, call (254) 527-5340 for a written estimate.
We do not keep large paver inventories on a shelf, because paver series, colors, and thicknesses vary too much to stock efficiently. We order Cambridge Pavers through their Houston distribution network and typically have materials on site within five to ten business days of contract signing. Same with matching brands like Belgard and Unilock when the original installation used a different manufacturer. Call (254) 527-5340 and we will verify what is actually installed at your property, then give you a written price and a delivery window.
No. The price we put in writing before the first shovel goes in the ground is the price you pay on the final invoice. If we find something unexpected beneath the pavers, like an undocumented utility line or a failed base we could not have seen from the surface, we stop, show you what we found, and give you a written change order before any work continues. No surprises at the door. That is the Kingswell Way, and it has been since 2004. If you are planning a paver project or addition, call (254) 527-5340 for a free estimate.
