Tremron Home Additions & ADU: The Sacramento Owner’s Guide
If you’re planning a Tremron home addition or ADU project in Sacramento, you’re looking at an installed cost between $45,000 and $130,000 for the addition itself, with ADU construction running $90,000 to $220,000 depending on square footage, foundation work, and finish level. We’re Penhallow Remodeling Sacramento, and while we’re an independent general contractor, not affiliated with Tremron, we work with Tremron products regularly on additions and accessory dwelling units throughout the city. Most homeowners reach out when their existing Tremron pavers, retaining wall blocks, or patio surfaces are failing, or when they’re ready to expand and want a contractor who’ll price the whole job in writing before a single block gets set.
The typical call starts the same way: “We’ve got Tremron pavers out back that are sinking,” or “We’re adding a room and we want the new hardscape to match the existing Tremron.” Either way, you’ve got a project that touches both structure and site work, and you need someone who can handle the addition and the Tremron-compatible surfaces as one job, not two separate crews with two separate schedules.
Which Tremron Models This Applies To
Tremron manufactures a broad line of concrete pavers, retaining wall blocks, and slab products, and the Sac-and-Transfer region sees heavy use of their Estate, Villa, and Olde Towne paver lines, along with Tremron’s Anchor and Diamond retaining wall systems. The compatibility gotcha most homeowners miss: Tremron pavers are sized in metric dimensions (typically 60mm, 80mm, or 100mm thickness), which means your existing patio or walkway has a specific depth profile. If you’re matching an addition’s hardscape to existing Tremron work, the new material has to match not just the face pattern but the thickness, or you’ll end up with a visible step where the old meets the new.
For identification, Tremron stamps the product series on the underside edge of most pavers, and retaining wall blocks will have a mold code cast into the back face. If the stamp has worn off, measure the thickness with a tape measure and note the paver’s surface texture. OEM Tremron material is what we recommend for any visible match work, because the concrete mix consistency and color batch process are more predictable than aftermarket equivalents. For buried or structural applications like base course and retaining wall fill, a quality aftermarket block from a Sacramento supplier can save real money without any performance difference.
Styles & brands we work with
Signs Your Tremron Home Additions & ADU Is Failing
- Pavers sinking or settling in low spots: In Sacramento’s clay-heavy soil, the ground expands and contracts with moisture through our wet winters and dry summers. If the base material under the Tremron pavers was skimped on during the original install, you’ll see puddling after rain and trip hazards along walkways.
- Retaining wall blocks leaning or bulging: A Tremron wall that’s starting to lean is usually a drainage problem. Water builds up behind the wall, saturates the soil, and pushes the blocks forward. Left alone, a bulging wall can fail completely within a season or two.
- Edge restraint failure along driveways and patios: When the plastic or aluminum edging that holds the outer row of pavers in place breaks loose, the pavers start creeping outward. You’ll see a widening gap along concrete abutments or the edges of the driveway slab.
- Cracks spreading through the paver surface: Hairline cracks in Tremron concrete are often from point loads, like a heavy vehicle on a driveway rated for pedestrian traffic, or from a base that wasn’t compacted in lifts. Surface cracks usually mean the paver is damaged, not the whole installation, but the cause needs checking.
- Weed and grass growth through joints between pavers: Polymeric sand joints fail over time, especially through Sacramento’s freeze-thaw cycles in winter. Once the sand washes out, weeds take hold, and the pavers start shifting because the joint material that locked them together is gone.

AfterReplacement Cost & What’s Included
For a Tremron home addition or ADU project in Sacramento, the $45,000 to $130,000 range for additions covers framing, foundation work, roofing, insulation, HVAC, electrical, plumbing, drywall, and finish work like flooring and paint. ADUs run higher, $90,000 to $220,000, because they include a full kitchen and bathroom build-out plus separate utility connections. The biggest cost drivers are square footage, the condition of your existing foundation, whether sewer or electrical service needs upgrades, and the level of finish, carpet and builder-grade fixtures land at the bottom of the range, while Cambria countertops, custom cabinetry, and premium flooring push toward the top.
Every job includes a written price before we start, a written 365-Day Done Right Promise, and material choices drawn from names like James Hardie for siding and Moen for fixtures. You get one number on day one, and that’s the number on the final invoice.
DIY or Call Us?
A home addition or ADU is not a DIY project, full stop. Foundation work, structural framing, electrical, plumbing, and HVAC all require permits and inspections here in Sacramento, and the city’s building department will not sign off on work that wasn’t done by properly licensed trades. Where Tremron hardscape is concerned, you can safely inspect the existing paver and wall condition yourself, checking for the settling, leaning, and edge failure signs we listed above. What you shouldn’t do is start pulling up pavers and re-setting them without understanding the base material underneath, because that base is what determines whether the repair lasts five months or twenty years.

FAQs
A properly installed Tremron paver patio or walkway should last 25 to 40 years in Sacramento, provided the base was compacted correctly and the edges are restrained. Tell me what you want the room to feel like, and I’ll tell you what it actually takes to get there. Call (279) 300-1177 for a paver assessment, estimates are free.
Yes, in many cases a leaning Tremron wall can be repaired by excavating behind it, installing proper drainage and filter fabric, and re-setting the affected blocks. If the wall has moved more than a few inches or the blocks are cracked, a partial rebuild is the honest fix. Call (279) 300-1177 and we’ll give you a straight assessment of what’s repairable and what isn’t.
A detached ADU in Sacramento typically runs 6 to 12 months from permit submission to final inspection, depending on the size, the site conditions, and how quickly the city reviews your plans. Garage conversions are usually faster, around 4 to 8 months. Call (279) 300-1177 for a timeline specific to your property.
We source Tremron products per job from local Sacramento supply yards, because the specific series, color, and thickness has to match your existing work. We also work with KraftMaid, Cambria, and Silestone materials when the project calls for them. Call (279) 300-1177 and we’ll verify availability for your exact Tremron pattern before we quote the work.
