Tremron Home Additions & ADU: The Los Angeles Owner’s Guide
If you have a Tremron product tied to a home addition or ADU project in Los Angeles and a component has failed or is failing, here’s what you need to know right now: a full home addition in Los Angeles runs $53,100 – $153,400, while ADU construction lands between $106,200 and $259,600. We stock and install Tremron-compatible hardscape and paving components that feed into these larger projects, and we can usually get a technician to your property within a standard scheduling window, not weeks out. Most Southern California owners discover a Tremron paver or wall block has failed when they see shifting, cracking, or drainage problems around a newer addition or ADU foundation line. The good news is that the part-level fix is usually far less expensive than the numbers above suggest.
Mason Remodeling is an independent service provider, not affiliated with Tremron. We work with Tremron products because we see them across Los Angeles driveways, patios, and retaining walls, and we know how they behave in our climate.
Which Tremron Models This Applies To
Tremron manufactures concrete pavers, retaining wall blocks, and hardscape accessories across several product lines, and the compatibility question matters more than most homeowners expect. The Tremron paver lines we work with most in Los Angeles are the Estate Series, the Olde Towne collection, and the Holland stone profiles. Each line uses slightly different dimensional tolerances, which means a replacement paver from the wrong series will sit proud of the surrounding surface by an eighth of an inch or more. You’ll feel it underfoot before you see it.
The quickest way to identify your Tremron part is to check the underside of a loose paver or the back face of a wall block. Tremron stamps most units with a mold code, a series identifier, or a two-letter plant mark. If the stamp has worn away from decades of sun exposure, measure the unit’s depth. Estate pavers typically run 60mm thick for residential use, while Olde Towne units are often 80mm. Mixing those up creates a trip hazard and a drainage problem in one stroke.
For replacement parts, OEM Tremron units are the safest match for color and dimensional consistency. Quality aftermarket equivalents exist, but we’re cautious with them on Tremron jobs because Tremron’s color blending, especially in the charcoal and Sierra tones, is hard to match from a different manufacturer’s palette. If you’re only replacing one or two units, OEM is the way. If you’re redoing a 400-square-foot patio, aftermarket options can save real money with acceptable color drift.
One Los Angeles-specific compatibility gotcha: Tremron pavers installed before 2010 in the San Fernando Valley and coastal zones were often produced at the former Irwindale plant, which used a slightly different aggregate mix than current production. A brand-new replacement unit can weather differently than the surrounding field after one rainy season. We flag this before ordering so you’re not surprised in February.
Styles & brands we work with
Signs Your Tremron Home Additions & ADU Is Failing
- Pavers sinking or settling near the addition’s foundation line. This usually means the base material under the pavers was never compacted properly, or a drainage issue is washing fines out from underneath. In Los Angeles, the freeze-thaw cycle is a non-issue, but our clay-heavy soils in the Valley expand and contract enough to shift a poorly prepared base.
- Retaining wall blocks leaning or bulging outward. A Tremron wall that moves is almost always a drainage failure behind the wall. Water builds up, adds weight, and the wall starts to lean. This is the most common ADU-adjacent failure we see in hillside neighborhoods like Mount Washington and Echo Park.
- Efflorescence, that white chalky film, appearing on pavers or blocks. It’s cosmetic, not structural, but it tells you moisture is moving through the concrete. On its own it’s a cleaning issue. If it keeps coming back after cleaning, you have a water source that needs addressing.
- Cracks running through individual pavers, especially near driveway edges. A cracked paver usually means point loading: a car tire, a heavy planter, or a downspout concentrating force in one spot. One cracked unit is an easy swap. A pattern of cracks across multiple units points to a base failure underneath.
- Gaps opening between pavers where joint sand keeps washing out. This is a drainage and erosion signal. In Los Angeles, our winter rains arrive fast and hard, and if the joint sand isn’t stabilized, those gaps widen every season until the pavers start moving independently.

AfterReplacement Cost & What’s Included
For Tremron-related hardscape work that supports home additions and ADUs in Los Angeles, you’re looking at $4,130 – $12,980 for paver patio installation, $8,260 – $21,240 for paver driveway installation, and $5,310 – $14,160 for concrete driveway installation, depending on scope. A focused repair, like replacing a half-dozen sunken pavers and re-compacting the base, will fall at the lower end or below these ranges. A full paver driveway replacement with new base material and edge restraints lands at the top.
Every job includes the written price before work starts. That price covers the parts, the labor, the base material if needed, and cleanup. You’ll know the crew member’s name and see their photo before arrival, and they’ll show a photo ID badge at the door. Mason Remodeling’s 365-Day Done Right Promise applies: if the work isn’t right within a year of completion, we make it right at no cost to you.
DIY or Call Us?
There are a few things you can safely check before calling anyone. Pull up a loose paver and look at the base underneath. If the base is dry, crumbly sand rather than compacted aggregate, that’s useful information. If a downspout is dumping water directly onto the paver edge, that’s something you can redirect with a simple extension. Those observations help us diagnose faster when we arrive.
What you shouldn’t do is start pulling up large sections of pavers or, worse, rebuilding a retaining wall. A Tremron retaining wall that’s leaning holds back hundreds of pounds of soil and hydrostatic pressure. Removing the wrong block or digging out the base without proper shoring can cause a sudden collapse. That’s not a weekend project. That’s a call to (803) 680-2547, where we’ll send someone who knows exactly how to stage the repair safely and in what order.
FAQs
In Los Angeles, properly installed Tremron concrete pavers typically last 25 – 40 years before the surface shows meaningful wear. The paver itself is not usually the failure point; the base underneath is. Our UV exposure fades color over time, and our clay soils shift with moisture, so the base preparation and drainage matter more than the paver’s age. Call (803) 680-2547 if you’re seeing settlement before year ten; that’s almost always a base problem, not a product problem.
Yes, in most cases a localized failure can be repaired by removing the affected pavers, re-compacting or replacing the base in that area, and relaying the same units. Full replacement is only necessary when the base has failed across a large area or the pavers themselves are cracked and beyond reuse. The free estimate we provide will tell you which path applies to your situation.
A small paver repair, like six to twelve sunken units, is usually a one-day job. A paver driveway section with base rework might take two to three days. A leaning retaining wall rebuild can take four to seven days depending on the wall’s height and whether drainage behind it needs to be installed. We’ll give you a written timeline with your written price, so you’re not guessing.
We carry common Tremron replacement units in standard colors and profiles on our trucks for most Los Angeles service calls, and we source OEM Tremron units for specific series matches through our material suppliers. If we don’t have your exact unit on hand, we’ll have it ordered and scheduled before we start the job. Call (803) 680-2547 and tell us the stamp on the back of your paver or block; we’ll tell you what we have and what we need to source.
