Tremron Home Additions & ADU: The San Diego Owner’s Guide
If you have a Tremron product involved in a home addition or ADU project in San Diego, and something’s not right with it, here’s what you need to know: a full home addition in San Diego typically runs $53,100 to $153,400, while an ADU construction project lands between $106,200 and $259,600. Mason Remodeling Co San Diego works with Tremron hardscape and pavers where they meet these projects, and we can assess, price, and fix what’s failing. Most homeowners discover the problem when a paver shifts, a retaining edge gives way, or a drainage channel stops doing its job, usually after the first heavy rain season or a few years of soil movement.
The reality in San Diego is that our clay-heavy soils and wet-dry cycles put real stress on any Tremron paver system that wasn’t built with proper base compaction. That’s not a knock on Tremron products (they make good concrete pavers and wall block). It’s a fact of our local ground. When the base fails, the pavers fail, and that’s when the calls start. Isaac Pruett, our owner, likes to say it plain: “Tell me what’s broken. I’ll tell you what it takes.”
We’re an independent San Diego contractor, not affiliated with Tremron. We install and repair Tremron-compatible hardscape systems as part of larger home addition and ADU work, and we stock the common repair parts on our trucks.
Which Tremron Products This Applies To

Tremron manufactures a range of concrete pavers, retaining wall blocks, and hardscape accessories. The compatibility question most San Diego homeowners face comes down to which product line they have installed, because not every Tremron block matches every application. The three we handle most often in home addition and ADU projects are standard segmental pavers (typically 60mm, 80mm, or 100mm thick), retaining wall units (which vary wildly in setback, face texture, and corner units), and the edge restraints and drainage fittings that hold the whole system together.
Here’s the compatibility gotcha most people miss: a 60mm Tremron paver is not interchangeable with an 80mm paver, even if it looks identical from above. The base depth, edge restraint height, and bedding sand layer are all built around that specific thickness. When an owner (or a less careful contractor) mixes them, the surface fails within a season because the load transfer isn’t uniform. For replacement, OEM Tremron pavers match color and dimension exactly, but quality aftermarket equivalents from hardscaping suppliers in San Diego exist for many standard patterns. We source both, depending on what the project needs and what’s already down.
If you’re not sure what you have, flip one paver over. The manufacturer name and plant code are usually stamped on the bottom of every Tremron unit. That read takes thirty seconds and saves everyone a lot of guessing.

Signs Your Tremron Home Additions & ADU Hardscape Is Failing
- Wavy or uneven paver surface. This almost always means the base layer has settled or washed out underneath. In San Diego, we see this most often after heavy winter rains, when water finds its way under the edges and carries the bedding sand away. The pavers themselves are usually fine, but the base needs rebuilding.
- Gaps opening between pavers. If your sand joints keep disappearing, the edge restraint has probably failed. Without a solid border holding the field in place, pavers drift outward under foot traffic and vehicle weight, and the joints keep widening.
- Sunken areas around downspouts or drains. This is a drainage failure, not a paver failure. Water is concentrating where it shouldn’t, eroding the sub-base and creating a low spot. You’ll see it get worse every time it rains unless the drainage path gets fixed.
- Cracked or chipped retaining wall blocks. Walls crack when the load behind them exceeds what the block and the setback can carry. Often this is a sign of poor drainage behind the wall, which adds hydrostatic pressure and turns a good block into a cracked one within a few years.
- Pavers shifting or rocking underfoot. A rocking paver means the bedding layer failed under that specific unit. It’s one of the earliest signs, and it’s worth catching before the problem spreads and takes down the neighboring pavers with it.
Replacement Cost & What’s Included

For Tremron-related hardscape repair within a San Diego home addition or ADU project, costs follow the scope. A localized paver repair (removing and resetting a sunken section with proper base material) typically falls in the $2,360 to $7,670 range, which matches general countertop or mid-size repair pricing. Full paver patio reinstallation runs $4,130 to $12,980, and paver driveway installation is $8,260 to $21,240. If the failure is inside the structure of the addition or ADU itself (foundation issues, framing corrections, roof tie-ins), home addition work is $53,100 to $153,400, and ADU construction is $106,200 to $259,600.
What drives the range on the hardscape side is the square footage, how deep the base problem goes, and whether we’re salvaging the existing pavers or bringing in new ones. Parts and labor are quoted separately, so you see exactly where your money goes. Every job gets a written price before work starts, and the repair carries our 365-Day Done Right Promise from the completion date. If something’s not right within that year, we come back and fix it at no cost.

Some things are worth checking yourself. If you see a single paver that’s cracked, you can lift it, look at what’s underneath, and confirm whether the base is solid or washed out. That’s useful information when you call us. What we’d caution against is the temptation to just add more sand and call it fixed. Sand doesn’t rebuild a failed base. It fills the gap for a few weeks and then the problem returns, usually worse.
Where we really recommend a trained set of hands is any repair involving retaining walls or pavers under vehicle load. A retaining wall that’s failing carries real weight behind it, and the failure doesn’t announce itself. A driveway paver system that’s sinking means the base is compromised, and a car parked on a bad enough section can make things considerably worse. We’re not going to talk you out of small fixes, but we’d rather come look at it before you invest a weekend in a repair that won’t hold. Call (619) 673-9302 and we’ll give you an honest read on what you’re dealing with.
FAQs

Tremron pavers installed on a properly compacted base in San Diego weather typically last 25 to 40 years, with most failures traceable to drainage or sub-base issues rather than the pavers themselves. Our wet winters and clay-heavy soils are the main threats, not sun exposure or surface wear. Call (619) 673-9302 if you’re seeing signs of failure and want to know how much life is left in your install.
A failing Section can often be repaired without replacing the entire hardscape, as long as the damage hasn’t spread to the edge restraints or the drainage system. We remove the affected pavers, rebuild the base and bedding layer, and reset the same units or matched replacements. Call (619) 673-9302 for an assessment of your specific area.
A typical localized paver repair near a home addition or ADU in San Diego takes one to two days, which includes base removal, compaction, resetting pavers, and re-sanding the joints. Larger areas like full driveway sections may take three to five days. We’ll give you a clear timeline with your written estimate before any work begins.
We keep common Tremron-compatible pavers, edge restraints, drainage fittings, and bedding materials on our trucks for most San Diego service calls, though exact color and pattern matches may require a quick supplier run. We’ll confirm what we need before we arrive whenever possible. Call (619) 673-9302 to describe what you’re looking at, and we’ll tell you what’s realistic.
