Tremron Construction in San Francisco, CA | Ashford Contractors
We’re Ashford Contractors, an independent Tremron installer serving San Francisco homeowners since our first paver driveway in the Outer Sunset and now offering Tremron in Mission District and across the city. We are not manufacturer-affiliated or authorized by Tremron; we’re a full-scope general contractor that chooses their pavers and wall block because they hold up. The one thing that makes our Tremron work different here? We plan every paver and wall project around San Francisco’s seismic hazard zones, fog-belt moisture, and soft-story garage aprons, not just the product specs. Call (877) 752-3868 for a free estimate on any Tremron paver driveway, patio, or retaining wall in San Francisco.
Why San Francisco Residents Choose Us for Tremron Service
Most contractors in San Francisco can lay a paver. Few can tell you why your Olde Towne driveway is blooming white after two foggy summers, or whether your Noe Valley slope needs geogrid before the base goes down. We work with Tremron’s full hardscape line, from Tremron sales & service through our own in-house crews, and we source genuine Tremron units plus matching cap and connector pieces so partial rebuilds match the original color and profile.
Glen Mossier, our owner, grew up in Foster City watching lagoon-side homes get rebuilt after water damage. He learned early that a paver is only as good as what’s under it. That’s why our Tremron work in San Francisco starts with the base, the drainage, and the soil, not the pretty top layer. We answer to the homeowner, not to a manufacturer program. If a Tremron paver is the wrong call for your site, we’ll tell you before you spend a dollar.

Common Tremron Construction Problems We Solve in San Francisco
- Efflorescence bloom on gray Olde Towne pavers. San Francisco’s cool, foggy summers slow the curing process and trap surface salts in the paver face. You get a chalky white film that won’t rinse off. We clean it properly and adjust the joint sand and sealing approach so it doesn’t return next fog season.
- Polymeric sand joint failure and base settlement on sloped driveways in Noe Valley and Bernal Heights. Wet winters saturate the sand, it washes out, and the base starts migrating downhill. The pavers heave, the surface ponds, and the joints open. We over-excavate, re-compact, and re-sand with a spec-grade polymeric blend that holds in San Francisco’s rain window.
- Paver spalling and edge chipping where units meet soft-story garage aprons. Soft-story retrofits under the city’s ordinance flex the framing at street level. That movement transfers to the pavers at the apron edge. We reset and re-restrain those edges after the seismic work is done, using properly compacted fill and edge restraint that tolerates the flex.
- Retaining wall face cracking and algae staining on shaded Stonewall II walls. North-facing walls in San Francisco’s fog belt stay damp for months. Algae takes hold, and moisture cycles through the block face. We rebuild with proper drainage behind the wall, geogrid where the soil’s sloped, and a cap detail that sheds water instead of holding it.
- Driveway replacement where the base has failed but the pavers are still sound. We pull the units, rebuild the base and drainage, and reset the same Tremron pavers when they’re structurally good. No upsell to a full tear-out unless the units themselves are done.
Tremron Service in San Francisco: What Local Conditions Mean for Your Equipment
Here’s the thing about San Francisco that most hardscape guides skip: because so much of the city sits inside Seismic Hazard Mapping Act liquefaction or landslide zones, Marina, South of Market, and the eastern waterfront especially, a Tremron paver driveway or retaining wall here often needs a geotechnical report and an over-excavated, geogrid-reinforced base before the first paver goes down. That’s not a suggestion. It’s the difference between a driveway that stays flat through ten wet winters and one that heaves after two. On a soft-story garage apron off Sanchez Street in Noe Valley, our crew pulled up a heaving Tremron Olde Towne driveway whose polymeric joints had washed out and whose base had settled over a wet winter, prompting us to expand our Tremron service in Noe Valley. We over-excavated to compacted aggregate, added geogrid, reset the sound pavers with fresh edge restraint, and re-sanded the joints. The garage door now clears a flat, drained surface instead of a ponding one. In San Francisco, the base is the project. The paver is the finish.
Tremron Models & Products We Service in San Francisco
We install and service the Tremron lines that actually show up in San Francisco yards and driveways: Olde Towne pavers, Plaza Series pavers, Brussels Block pavers, and Stonewall II retaining wall block. When we rebuild part of a wall or driveway, we source genuine Tremron units and matching manufacturer connector and cap pieces so color and profile stay consistent. For base aggregate, polymeric sand, and geogrid, we specify quality aftermarket materials that outperform the boxed kit. We stock common Tremron profiles locally for fast San Francisco turnaround, and we keep the full catalog on order for larger phased projects. If you need a specific series matched, we’ll pull the manufacturer code before we quote.

FAQs – Tremron Construction in San Francisco
The Planning Department’s discretionary review can add weeks to any exterior project in San Francisco, especially on sloped lots or in neighborhoods with active neighborhood associations. A paver driveway that would take two days in Foster City can take two months here once review and permits are factored in. We handle the paperwork and the sequencing so the hardscape work slots in cleanly once approvals land. Call (877) 752-3868 and we’ll walk you through what your specific site triggers.
No, and that’s deliberate. We’re an independent general contractor. We choose Tremron pavers and wall block because they perform, not because a manufacturer program tells us to. That independence means we’ll tell you when a Tremron unit is wrong for your San Francisco site and recommend something else from our hardscape roster instead.
For pavers, cap pieces, and connector units, we source genuine Tremron so color and profile match on partial rebuilds. For polymeric sand, base aggregate, and geogrid, we specify aftermarket materials that perform better than boxed kits in San Francisco’s wet winters and sloped lots.
A standard paver patio is done in three to five working days once the base is prepped. A driveway replacement with over-excavation and geogrid runs a week to ten days depending on slope and access. Soft-story garage aprons that need seismic coordination add time on the front end, not the back. We’ll give you a schedule with your estimate.
Paver driveway installation in San Francisco runs $8,260 to $21,240. Driveway replacement, where existing pavers or concrete are pulled and the base rebuilt, runs $5,900 to $16,520. The spread comes down to slope, soil, and whether your site sits in a liquefaction zone requiring geogrid. Call (877) 752-3868 for an exact quote. Estimates are free.
