Tremron Home Additions & ADU: The Pasadena Owner’s Guide
Home additions and ADU projects built with Tremron products in Pasadena typically run $45,000 – $130,000 installed, depending on square footage, foundation work, and how much of the existing structure we’re tying into. Most Pasadena homeowners find out something’s failed when they notice a crack along a Tremron paver seam, a shifting step, or water pooling where it didn’t before. We stock Tremron-compatible replacement materials and matching pavers, and we can usually source exact-match pieces within a few business days.
What we see most often in Pasadena isn’t a catastrophic failure. It’s the slow stuff: a paver edge that’s drifted, a retention wall block that’s tilted forward after a wet winter, a step that’s settled half an inch and now catches the toe of a kid’s shoe. Tremron products are solid, but Pasadena’s clay-heavy soil expands and contracts through our dry summers and wet winters, and that movement finds every weak joint eventually. The good news is that most of these failures are repairable without tearing out the whole addition or ADU. We’ll walk you through what’s actually wrong and what it costs to fix, in writing, before we touch anything.

Which Tremron Models This Applies To
Tremron makes a wide range of concrete pavers, retaining wall blocks, and segmental wall systems used in home additions and ADU builds across Pasadena. The compatibility question matters because Tremron has changed their product lines over the years, and a paver that was manufactured in 2015 may not have an exact color or texture match in today’s lineup. Here’s what to check before you assume a replacement part will blend.
First, look at the back or bottom of any loose paver or block you can safely lift. Tremron stamps most products with a manufacturing code and batch number. That code tells us which plant it came from, which is useful because Tremron runs multiple production facilities and there can be slight color variation between them. Second, measure the actual dimensions: Tremron pavers are metric-sized in many cases (80mm, 60mm thickness), which means a “standard” paver from another manufacturer won’t sit flush. We’ve seen Pasadena homeowners buy what looked like the same paver at a big-box store, only to have it ride a quarter inch high because the metric thickness didn’t match.
For retaining walls and ADU foundations, the key spec is the block’s structural rating. Tremron wall systems are engineered for specific load heights, and swapping in a lighter block because it looks similar is a real problem. We always match the original Tremron series, and where an exact OEM match is discontinued, we source quality aftermarket equivalents that match the dimension and load spec, not just the color. We keep common Tremron replacement pavers and edge restraints in stock, and we can order odd-size or discontinued pieces direct through our supplier network, usually within three to five business days in Pasadena.

Signs Your Tremron Home Additions & ADU Is Failing
Most of these show up gradually, then suddenly feel urgent. Here’s what we look for when we walk a Pasadena property:
- Water pooling against the addition or ADU foundation. This usually means the Tremron pavers have settled or the slope has flattened over time, so runoff no longer drains away from the structure. In Pasadena’s winter rains, that standing water works its way under the slab and accelerates cracking.
- Cracked or chipped pavers along walkways and steps. Often the result of clay soil movement, tree roots, or a heavy delivery truck. A single cracked paver is a quick swap. A line of cracks across the whole pad suggests shifting below the surface, and that needs regrading, not just replacement.
- A retaining wall that’s leaning or bulging forward. This is the one we take most seriously. A Tremron segmental wall that’s moving outward means the soil pressure behind it has changed, usually from poor drainage. If it’s more than a few degrees out of plumb, the fix is rebuild, not patch.
- Gaps opening between pavers and the house foundation. The soil under the pavers has compacted unevenly, and those gaps let water in. We fill and compact those zones, but we also check whether the original base was deep enough for Pasadena’s soil conditions. If it wasn’t, we’ll tell you honestly that patching will fail again.
- Uneven step heights or a sunken pad near the ADU entrance. This is how families notice first: a child trips, an older parent catches a shoe. It’s usually localized base failure. The fix is lifting the section, re-compacting the base, and relaying the Tremron units to match the surrounding grade.

AfterReplacement Cost & What’s Included
For Tremron home additions and ADU repair work in Pasadena, you’re looking at a range that shifts based on scope. A single cracked paver or a small section of settled walkway is a repair call, typically in the low hundreds. Rebuilding a retaining wall or replacing a large paver pad that’s failed runs into the thousands. A full ADU addition or new build beyond the existing structure lands in that $45,000 – $130,000 range.
Every quote we write includes the same things, and that’s a promise Graham Stein makes every time he walks a Pasadena property: line-item parts and materials with the Tremron product name on the page, labor broken out so you can see what you’re paying for, waste hauling, and the base or drainage repair if that’s what’s actually wrong underneath. No allowances buried in the fine print. The price you see on paper is the price you pay at the end – no footnotes.
We pull permits when Pasadena’s building department requires them, and we stand behind the work with a 365-Day Done Right Promise: if it’s not done right, we make it right. Named-brand materials from Tremron, plus our partner cabinet and surface brands like KraftMaid, Cambria, and Silestone, carry their own manufacturer warranties you can verify independently.
DIY or Call Us?
A single cracked paver in the middle of an otherwise sound pad is a job a handy homeowner can handle: lift the damaged unit, check the base, drop in the replacement. If you’re comfortable with that, go for it. Where we draw the line is anything involving a retaining wall above knee height, a settled foundation, or a drainage problem that’s sending water toward the structure. A leaning Tremron wall under soil pressure can fail suddenly if you start pulling blocks without the right shoring, and that’s a risk no weekend project is worth.
What you can safely do before calling: take photos of the damaged area from a few angles, note where water sits after a rain, and measure the paver dimensions so we know what we’re matching. Then call us at (626) 714-2992. We’ll send someone out to look, and the estimate is always free.
FAQs
Tremron concrete pavers in Pasadena’s climate typically last 25 – 40 years or more when the base was installed correctly and drainage is maintained. The pavers themselves rarely fail first. What shortens their life here is clay soil movement and poor drainage, which undermine the base and cause settling, shifting, and cracking long before the paver material itself wears out. Call (626) 714-2992 and we’ll tell you whether the paver or the base is the problem.
No, a cracked paver can’t be repaired in place; it’s swapped for a matching unit. The repair is usually quick and inexpensive if we can find an exact match, though color matching gets harder with older Tremron batches. We’ll tell you honestly if the replacement will be visible, and whether rotating an existing paver from a less noticeable spot gives a better look.
A single paver swap or small section rebuild usually takes one day on site. A retaining wall rebuild or large pad replacement typically runs three to seven days, depending on access and whether we need to recompact the base. We work with quiet tools during family rest hours where possible, and we leave a photo of the clean-up before the crew pulls out of your driveway.
We keep common Tremron paver sizes, edge restraints, and wall caps in stock, and we can order less common or discontinued pieces through our supplier network, typically arriving in Pasadena within three to five business days. If you have the stamped code from the back of an existing paver, send us a photo and we’ll confirm the exact match before we quote the work. Estimates are free.
If you’re dealing with a failed Tremron surface on a home addition or ADU in Pasadena, call us at (626) 714-2992 and we’ll send someone out to look. You’ll get a written, line-item price before any work starts, and we’ll leave your home the way we found it: floors protected, site cleaned, and a photo of the finished clean-up in your hand.
