Techo-Bloc Home Additions & ADU: The Los Angeles Owner’s Guide
If you’re planning a home addition or ADU in Los Angeles with Techo-Bloc hardscape and masonry products, the full project typically lands between $53,100 and $153,400 installed, with dedicated ADU construction running $106,200 to $259,600 depending on size, site prep, and finish level. We work with Techo-Bloc pavers, walls, and steps as part of the larger build, and we can tell you exactly how the material package fits into your overall budget before any work starts. Most owners call us because they’ve been quoted a number by one contractor, then watched it climb once the job got going, and they want a written price that holds.
Here’s what we see across LA neighborhoods from Silver Lake to Woodland Hills: a homeowner has a Techo-Bloc paver patio or retaining wall that’s shifting, cracking, or separating, and they’re trying to figure out whether to patch it or fold the repair into a bigger addition. That’s where this page starts.
Key Takeaways
- Full home additions with Techo-Bloc work in Los Angeles: $53,100–$153,400
- Standalone ADU construction: $106,200–$259,600
- We’re an independent contractor, not a Techo-Bloc dealer or affiliate
- Written price before work starts, no change orders unless you approve them first
Which Techo-Bloc Models This Applies To
Techo-Bloc’s product lines show up all over LA additions and ADUs, and they are not interchangeable. The Blu 60 paver, for example, is a 60mm-thick unit rated for driveways and heavier loads, while the Mista and Travertina lines run thinner and are meant for patios, walkways, and pool decks. If someone installs a patio-rated paver where a car will drive, you’ll get cracked units within a season or two. Same goes for walls: the Mini-Creta retaining wall block is not the same structural animal as the Presencia or Raffinato lines, and the wrong pick on a sloped LA lot is a wall that leans by the second winter rain.
For OEM versus aftermarket: Techo-Bloc manufactures its own units in proprietary molds, so there is no true generic equivalent that matches color, texture, or joint spacing. You can find lower-cost paver brands that approximate the look, but the edge profiles and color blends will not match a partial repair. If you’re extending an existing Techo-Bloc surface, buy Techo-Bloc. If you’re starting fresh and the budget is tight, we’ll show you comparable alternatives and let you decide with real numbers in front of you.

Signs Your Techo-Bloc Home Additions & ADU Is Failing
- Pavers settling or sinking in traffic areas. Usually a base-prep problem, not a paver problem. LA’s clay-heavy soils expand and contract with moisture, and if the aggregate base wasn’t compacted in lifts, the surface follows the soil.
- Joint sand washing out after rain. Polygon jointing sand was either skipped or installed dry. Once water gets under the pavers, the base erodes and the whole section starts moving.
- Retaining wall leaning or bulging. This is a drainage and backfill failure. Without proper weep holes and gravel behind the wall, hydrostatic pressure pushes the wall out. We see this constantly in hillside areas like Echo Park and Mount Washington.
- Efflorescence, the white chalky haze on the surface. Common with concrete pavers in LA’s dry-wet cycles. It’s cosmetic and removable, but if it keeps returning, moisture is trapped under the sealer or the paver bed isn’t draining.
- Edge restraints failing along borders. When the plastic or aluminum edge is staked too shallow, pavers walk outward and the clean line of your patio or walkway turns wavy within a year.

Every quote includes parts, labor, base prep, haul-away, and a written line-item breakdown. The price you approve is the price on the invoice. The 365-Day Done Right Promise covers the work in writing for a full year after close-out.
DIY or Call Us?
For a few loose pavers on a small patio, a homeowner with a rubber mallet, some joint sand, and patience can often reset them. But here’s the honest version: if you’re seeing multiple pavers shift, a wall lean, or water pooling where it didn’t before, the problem is usually underneath the surface. Digging out and re-compacting a base on a Los Angeles hillside lot is not a weekend project, and getting it wrong means paying for the same repair twice.
If it’s a retaining wall that’s leaning or bulging, do not stand near it and do not try to brace it yourself. That wall can come down fast when the soil behind it is saturated. Call us at (254) 272-5876 and we’ll come look at it before it becomes an emergency.
FAQs
With proper base prep and drainage, Techo-Bloc pavers installed in LA hold up for 25 to 35 years before the surface shows real wear. The base underneath typically fails before the paver does, which is why we spend more time on subgrade than on laying the units.
Yes, if the rest of the surface is sound and the failing section is localized. We can match existing Techo-Bloc units and blend the repair area, but understand that color matching on older concrete pavers is close, not exact. Call (254) 272-5876 for a site look and we’ll tell you plainly whether a repair makes sense or replacement is the better spend.
Most Los Angeles home additions run 3 to 6 months from permit to punch list. ADUs run 6 to 10 months depending on utility work and city inspections. Techo-Bloc paver and wall work within the build usually occupies 1 to 3 weeks of that timeline.
We order Techo-Bloc directly per project, so the units arrive matched from the same production run. We don’t stock pallets on a truck, which means no mismatched colors or sun-faded units stacked in a yard. If you need us to source a specific Techo-Bloc line for your addition or ADU, we’ll pull pricing and lead times before you commit.
