Tremron Home Additions & ADU: The Los Angeles Owner’s Guide
If you’re planning a home addition or ADU and want Tremron-compatible hardscape and paver work tied into it, we install and match Tremron products as part of full additions and ADU builds across Los Angeles. A complete home addition with Tremron pavers, walkways, or retaining walls typically runs $53,100 to $153,400 installed, while a full ADU construction project lands between $106,200 and $259,600. Most owners reach out to us after they’ve already pulled permits and hit a snag: the paver base has shifted, the drainage got undersized, or a retaining wall started leaning because the original contractor cut corners on compaction.
We’re an independent Los Angeles remodeling and construction company. We’re not affiliated with Tremron, but we work with their pavers, walls, and hardscape systems regularly on additions and ADU projects, and we stock common Tremron-compatible materials on our trucks for small fixes and matching work.
Before we get into pricing and process, here’s what matters most: every addition or ADU we touch gets a written price before any work starts. You’ll know who’s showing up, by name and photo, before they ring the bell. And the work is covered by our 365-Day Done Right Promise: if something isn’t right within a year of completion, we make it right at no cost to you. That’s how Isaac Pruett has run Mason Remodeling Co since we started serving Los Angeles homeowners.
Which Tremron Models This Applies To
Tremron manufactures segmental retaining wall blocks, concrete pavers, and permeable paver systems across several product lines. The ones we see most often on Los Angeles additions and ADUs are the Olde Towne paver series, Village paver series, and the StoneWall retaining block line. Each has different joint widths, bed depths, and edge restraint requirements, so matching the right Tremron product to an existing patio or walkway matters more than most people expect.
Here’s the compatibility gotcha we run into constantly: Tremron pavers are manufactured in regional plants, and color lots vary. If you’re adding onto an existing Tremron patio, you can’t just order “the same color” and expect a match. You need the original lot number, or we need to pull a physical sample and have it matched at the distributor. Los Angeles sun also fades pavers unevenly depending on exposure, so a five-year-old patio will almost never match a brand-new paver, even from the same lot. We’ll tell you that up front and show you what a realistic match looks like before you spend a dollar.
For OEM versus aftermarket: Tremron doesn’t sell “parts” in the traditional sense. The product is the paver, block, or cap itself. What fails on an addition or ADU is almost always what’s under the Tremron product: the base rock, sand bed, geotextile fabric, or edge restraint. We stock the right gradations of crushed stone and sand, geotextile, paver restraints, and polymeric joint sand on our trucks. When it comes to replacing individual pavers or wall caps, we source directly from Tremron-authorized distributors in Los Angeles, which means you’re getting genuine Tremron product, not a lookalike.
Styles & brands we work with
Signs Your Tremron Home Additions & ADU Is Failing
- Pavers are sinking or creating a low spot where water pools. This almost always means the base wasn’t compacted properly, or the original contractor skimped on base depth. Los Angeles clay soil expands and contracts with moisture, and a thin base will shift within the first year or two.
- Sand or joint material washes out after rain. If you see sand collecting at the edge of your Tremron patio or walkway after a storm, the joints are failing. Left unaddressed, the pavers will start to shift and chip against each other.
- A retaining wall is leaning or bulging outward. This is the one we treat with real urgency. A leaning wall usually means inadequate drainage behind it, insufficient geogrid reinforcement, or both. In Los Angeles hillside neighborhoods, a failed retaining wall can threaten a foundation or ADU structure.
- Edge pavers are separating from the border or sinking along the perimeter. Edge restraints that weren’t installed or were undersized let the whole field drift. This shows up first along walkways and driveway edges.
- Efflorescence or color loss that’s uneven across the surface. White chalky residue is common to a degree, but if large patches look washed out while others look fine, you’re seeing sun damage combined with sealer failure. Some Los Angeles homes with southern exposure get hit hard by UV on one side of a patio.
Replacement Cost & What’s Included
For a full home addition that includes Tremron hardscape work, expect $53,100 to $153,400 in Los Angeles depending on square footage, site prep, and design complexity. A complete ADU build runs $106,200 to $259,600. If you’re repairing or replacing existing Tremron pavers or a retaining wall on an addition that’s already built, smaller paver patio repairs in Los Angeles typically fall in the $4,130 to $12,980 range, and driveway or retaining wall fixes scale from there depending on scope.
What’s included in every Tremron-related job we quote: a written line-item price before work starts, all base preparation and compaction, geotextile fabric where needed, edge restraints, polymeric sand, and the Tremron product itself. We pull permits when the scope requires it, and we schedule inspections so you’re never guessing about code compliance. The finished work carries our written guarantee, and if anything fails within 365 days of completion, we come back and fix it at no charge. That’s not a verbal promise. It’s in writing, every time.

AfterDIY or Call Us?
If you have loose pavers or a popped edge restraint, you can safely inspect the area and take a few photos to send us. Checking whether a low spot collects water or whether sand is washing out is something any homeowner can do. Replacing a single paver that’s cracked is also manageable if you’re comfortable lifting it and re-setting it on fresh sand.
What you shouldn’t DIY: anything involving a retaining wall that’s leaning, a base that has failed over a large area, or drainage that’s undermining an ADU foundation or hillside slope. Retaining wall failures in Los Angeles can destabilize soil quickly, especially after heavy rain. If a wall is visibly moving, call us at (213) 632-5711 before you park anything heavy near it or walk under it. We’ll send a crew lead with the name and photo you already have in hand, and you’ll get a written assessment without pressure.
How Much Does a Tremron Paver Repair Cost in Los Angeles?
A small Tremron paver repair in Los Angeles, like resetting a dozen sunken pavers or re-sanding joints, typically costs $470 to $2,125 depending on access and the condition of the base underneath. If the base itself has failed, you’re looking at a partial or full re-installation, which pushes the job into the $4,130 to $12,980 range for a typical patio. We’ll give you a written line-item quote before anything gets torn out, and the price doesn’t change once work starts. Call (213) 632-5711 for a free estimate and an honest assessment of what’s worth repairing versus replacing.
FAQs
Tremron concrete pavers typically last 25 to 40 years in Los Angeles when installed on a properly compacted base with adequate drainage. The pavers themselves rarely fail. What shortens their useful life is base failure, poor drainage, and Los Angeles sun degrading sealers faster than most manufacturers predict.
Yes, in most cases. If the base is still stable and the failure is limited to a specific area, we can lift the affected pavers, re-compact or add base material, and reset them. If the base has washed out or the compaction was never done right across the whole field, a full re-install is the honest long-term fix, and we’ll tell you which one you’re actually facing. Call (213) 632-5711 and we’ll assess it on site.
A small paver repair is usually a one-day job. A full patio re-install takes two to four days. A retaining wall repair or rebuild depends on height, access, and whether drainage improvements are needed, but most Los Angeles residential walls take three to seven days once permits are cleared.
We stock common Tremron-compatible base materials, joint sand, and edge restraints on our trucks, and we source genuine Tremron pavers and wall blocks from authorized Los Angeles distributors with a one-to-three-day turnaround for most product lines. If you need an exact color match for an existing installation, we’ll pull a sample and have it matched before you commit to anything.
