Tremron Home Additions & ADU: The Thousand Oaks Owner’s Guide
If you own a Tremron product and you’re planning a home addition or ADU in Thousand Oaks, the most common starting point is a foundation and hardscape assessment, not a trip to a showroom. We install and build Tremron-compatible additions and ADUs, and in the Thousand Oaks market, a full home addition runs $45,000 to $130,000 while an ADU typically lands between $90,000 and $220,000. Most Thousand Oaks homeowners discover they need our help when an existing hardscape or paver foundation underneath an older addition starts shifting, cracking, or letting water pool against the structure. The good news: we stock Tremron paver and block components on our trucks for quick turnaround on the structural base work, and we’re usually on site within a few days of your call.
Mason Remodeling Co Thousand Oaks is an independent service provider and is not affiliated with Tremron. We work with Tremron products because Thousand Oaks homeowners already have them, and because they hold up well in our dry summers and wet winters when installed correctly.
Which Tremron Models This Applies To
Tremron manufactures a range of concrete pavers, retaining wall blocks, and edge restraints used in residential hardscape and structural base work. When you’re building a home addition or ADU in Thousand Oaks, the Tremron components that matter most are typically the Tremron patio pavers (used for the walkway or patio leading to the new structure) and Tremron wall blocks (used for raised planters, retaining walls, or stem-wall facing). The key identification step is to check the underside of any loose paver or the back face of any wall block for a stamped Tremron name or a date code. Sizes vary by series: the common 12-inch square pavers measure 11-5/8″ x 11-5/8″ with a 3/8″ joint gap, while larger 16-inch series pavers actually measure 15-5/8″ x 15-5/8″. If your addition or ADU sits on a concrete slab, Tremron pavers may not be structural at all, but they often finish the surrounding walkways and patios, which is where Thousand Oaks owners first notice shifting or heaving.
For OEM versus aftermarket on Tremron work, here’s what matters: Tremron pavers and blocks are concrete-based and site-specific. There is no meaningful “generic” equivalent because color blends and surface textures are proprietary. You can use a different manufacturer’s paver for a repair, but the color won’t match, and in direct Thousand Oaks sun, the mismatch becomes obvious within a year. We carry Tremron-compatible edge restraints and joint sand on our trucks, and we order matching Tremron pavers and blocks directly through local Thousand Oaks suppliers when the job calls for exact color matching.

Signs Your Tremron Home Addition or ADU Foundation Work Is Failing
- Pavers are sinking or rocking underfoot. This usually means the base layer beneath the pavers has washed out or was never compacted adequately. In Thousand Oaks, our clay-heavy soil expands and contracts with moisture, which slowly undermines the base over a few wet winters.
- Gaps are opening between pavers near the addition’s edge. Edge restraint failure is the culprit most of the time. Without a solid perimeter restraint, pavers drift outward under foot traffic, and the whole surface begins to spread.
- Water pools against the addition or ADU foundation after rain. This is a grading or drainage issue, often tied to pavers that have settled below the level of the foundation. Standing water against a Thousand Oaks home addition invites moisture intrusion and foundation staining.
- Retaining wall blocks are leaning or bulging. Tremron wall blocks rely on proper drainage behind the wall. When drain rock is missing or a drain pipe is clogged, hydrostatic pressure builds after winter rains and slowly pushes the wall out of plumb.
- You see hairline cracks running across a patio paver adjacent to the new addition. In Thousand Oaks, soil movement is common on hillside lots near Lang Ranch and North Ranch. Cracks often mean the slab or base beneath the pavers moved after a heavy rain cycle.

AfterReplacement Cost & What’s Included
For Tremron-related work tied to a home addition or ADU in Thousand Oaks, pricing breaks into two buckets. Foundation and hardscape repair (re-compacting a washed-out paver base, replacing edge restraints, re-grading drainage) typically runs $3,500 to $11,000 depending on square footage and how much base material needs to be removed and replaced. Full addition or ADU construction that includes new Tremron hardscape runs $45,000 to $130,000 for an addition and $90,000 to $220,000 for a detached ADU in Thousand Oaks.
Every Mason Remodeling job includes a written price before work begins. That price covers demolition of the failed surface (if needed), new base material, Tremron pavers or blocks, edge restraints, joint sand, and labor. We also pull permits when the project requires them, and we include a written guarantee with every project: 365 days from the completion date, covering workmanship and any failure tied to our installation. If something fails inside that year, we return and make it right at no charge.
The biggest driver of cost in Thousand Oaks is access. Hillside lots with narrow driveways or tight side yards require more hand-carrying of material, and that adds labor hours. Flat lots in neighborhoods like Newbury Park or central Thousand Oaks generally come in at the lower end of these ranges.
DIY or Call Us?
There are a few things an owner can safely check: loose edge restraints, pavers that have shifted an inch or two, joint sand that has washed out. You can sweep sand back into joints and reset a loose restraint spike without much risk. What you shouldn’t do is attempt to re-grade a foundation perimeter, rebuild a retaining wall over three feet tall, or remove and re-compact a base layer. That work involves excavating under or near a structure’s foundation, and getting the compaction and drainage wrong will just repeat the failure. In Thousand Oaks, with our expansive soils, an improperly compacted base will settle unevenly within one season.

FAQs
Properly installed Tremron pavers and wall blocks last 25 to 40 years in Thousand Oaks, but the base beneath them typically needs attention every 10 to 15 years due to our clay soil’s freeze-thaw and moisture movement. If your pavers are less than a decade old and already failing, the base or drainage was probably done wrong the first time. Call (805) 309-3386 and we’ll evaluate what’s underneath before recommending a full replacement.
Yes, in many cases we can repair rather than replace. If the issue is localized sinkage, a washed-out base, or a failed edge restraint, the fix is often $3,500 to $6,000 and takes one to three days. Full replacement only becomes necessary when the pavers themselves are cracked or the base has failed across most of the surface. We’ll give you a straight answer on repair versus replace when we inspect the site.
A focused paver or wall repair near a Thousand Oaks home addition takes one to three days on site.
