Ashford Contractors installs and repairs Tremron hardscape systems as an independent contractor offering Tremron in Pacifica and nearby communities. We’re not manufacturer-affiliated, not authorized, and not pushing a brand sales sheet. What we are: crews who know exactly how Tremron Weston Wall, Olde English Wall, Capri Paver, and Barcelona Paver perform in Colma’s fog-belt conditions. That matters more here than anywhere else in San Mateo County.
Colma is a town of roughly 200,000 permanent residents, nearly all of them in cemeteries. There are only a few hundred living residents. So when we’re called to Colma, it’s rarely a backyard patio. It’s a cemetery terrace, a columbarium grade change, a commercial driveway off El Camino Real. The project owner is usually a cemetery district. The ground underfoot may hold more than you planned for. We’ll get into all of that below.
Why Colma Residents Choose Us for Tremron Service
Glen Mossier, our owner, grew up in Foster City’s Marlin Cove and trained in construction technology at Skyline College in San Bruno. He spent his early career watching Bay Area homes get rebuilt after water damage and learning what actually holds together through decades of coastal fog. That background shapes how we approach Tremron work here: detail the drainage first, then set the block.
Colma isn’t a big market for residential pavers. It’s a market for segmental retaining walls, cemetery terraces, and commercial hardscape that has to survive constant damp and institutional maintenance schedules. We carry genuine Tremron caps, corner units, and matching paver lots so repairs don’t turn into two-tone patch jobs. When a cemetery district needs a submittal with block-color approvals, we know how to put the package together. When a property manager on El Camino Real needs a paver field re-sanded and re-edged without closing the lot for a week, we do it.
We’re one of the few general contractors in the Bay Area who works across hardscape, roofing, windows, and full interior remodels. That matters less in Colma than in a residential city, but it means we see the whole site, not just the paver layer. Your project, not our portfolio.

Common Tremron Construction Problems We Solve in Colma
- Efflorescence on Tremron wall units. Colma sits in the fog belt just south of San Francisco. Cool, damp air keeps masonry surfaces wet for weeks at a time. That persistent moisture pulls calcium salts through Tremron segmental units, leaving white bloom that looks like structural damage. Cleaning it off only works if you fix the drainage behind the wall. Otherwise it comes back every fog season.
- Paver joint sand washout and shoulder migration. Tremron pavers on commercial driveways and cemetery paths sit in saturated base aggregate for much of the year. The paver field creeps toward the free edge, joints lose sand, and the edges start to wander. We re-detail the base with free-draining stone and re-sand with the right gradation before resetting the perimeter edge.
- Moss and algae in chamfered joints. Low-sun exposures along cemetery fence lines and north-facing wall faces grow moss inside Tremron paver chamfers. The moss lifts joint sand, holds water against the unit, and accelerates block movement on retaining walls. Colma’s fog makes this a year-round issue, not a seasonal one.
- Base and geogrid failure behind Tremron retaining walls. Cemetery-district grade changes concentrate water behind segmental walls. When the base isn’t free-draining or the geogrid isn’t properly layered, you get wall face rotation and cap displacement. The blocks themselves rarely break. The structure behind them fails.
- Dye-lot mismatch after partial repairs. Cemetery districts often repair one terrace section at a time. If the replacement Tremron units come from a different production lot, the color is off by a shade or two and the repair is visible from across the lawn. We buy genuine Tremron matching lots and keep records of what was installed on each section.
Tremron Service in Colma: What Local Conditions Mean for Your Equipment
There’s a fact about Colma that shapes every Tremron job here: the cemetery districts act as the property owner on nearly every hardscape project in town, and many of them specify segmental retaining wall systems like Tremron for grade changes and columbarium terraces. Submittal and block-color approval runs through a district, not a homeowner. That’s not how it works in Daly City or South San Francisco, where a property owner just signs the change order. In Colma, you’re coordinating with a land-use entity that manages perpetual-care grounds, irrigation, and burial records. That same perpetual-care irrigation keeps the soil behind Tremron walls saturated year-round, which is why drainage detailing matters more here than block strength. A wall that would drain fine in Redwood Shores stands in wet soil for months in Colma. We design for that reality from the first course.
On an El Camino Real service property backing onto cemetery ground, a Tremron Weston Wall retaining a columbarium terrace had rotated about two inches at the face. White efflorescence streaked every unit and the lower courses had lost their joint sand. Our crew pulled the affected courses, reset the base with free-draining aggregate, added a drainage composite and outlet at the district’s easement line, then reinstalled the original Tremron units with fresh caps and clean joint sand. Two fog seasons later the wall is plumb and the bloom has not returned.
Tremron Models & Products We Service in Colma
We work with the full Tremron lineup that Colma’s cemetery districts and commercial property owners specify. Tremron Weston Wall for segmental retaining walls and terrace retaining. Tremron Olde English Wall where an aged finish is requested. Tremron Capri Paver for commercial driveways and parking aprons along El Camino Real. Tremron Barcelona Paver for patio and walkway surfaces with a tighter joint pattern.
For repairs, we buy genuine Tremron wall caps, corner units, and matching paver lots so color and dimension stay consistent across the repair. Mismatched dye lots are the fastest way to make a patched wall look patched. We keep records of product codes and lot numbers for every Colma project we touch, so when a terrace section needs work in five years, we pull the right match.
On a sound wall or paver field, we repair and re-detail drainage rather than tear out. Once base failure or face rotation is structural, replacement of the affected course is the honest call. We’ll tell you which one you’re looking at.

AfterTremron Service Pricing in Colma
What does Tremron work cost in Colma? Here’s where the numbers land for the hardscape services we handle most often in this market. These are installed ranges, not materials-only figures.
| Service | Price Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Concrete Driveway Installation | $4,500 – $12,000 |
| Paver Patio Installation | $3,500 – $11,000 |
What drives the cost in Colma specifically? Cemetery-district approvals and submittals add administrative time. Excavation near burial grounds can trigger archaeological or coroner protocols that most contractors never encounter, and that adds time and documentation. Drainage detailing behind retaining walls in saturated soil is not a step you can skip. A free estimate from us is a site walk, a written line-item quote, and a clear read on whether you’re looking at a repair or a replacement. Call (877) 752-3868 to schedule one.

FAQs – Tremron Construction in Colma
Yes, and this is one of the most common requests we get from Colma’s cemetery districts. We pull the original product code and lot number from the existing wall, then source genuine Tremron units from the same or closest available manufacturing lot. If an exact match isn’t available, we’ll tell you before we quote the job, not after the block arrives on site. A partial repair should not announce itself from across the lawn.
White stains on Tremron block in Colma are almost always efflorescence, not product failure. The town’s persistent coastal fog keeps masonry saturated for weeks at a stretch, and water moving through the wall carries soluble salts to the surface, where they crystallize as white bloom. Cleaning the face removes the stain temporarily but does nothing to the water source. The permanent fix is drainage correction behind the wall: free-draining backfill, a drainage composite, and a proper outlet. We quote that repair as a complete system, not a face wash. Call (877) 752-3868 for an exact quote, estimates are free.
On many parcels along the El Camino Real strip in Colma, yes. The cemetery districts own property that fronts onto El Camino Real, and boundary easements can extend into what looks like a standard commercial parking area. We verify ownership and easement lines before we price the job. If district approval is needed, we prepare the submittal with product specifications, block color, drainage details, and a site plan. You won’t find out after excavation has already started.
Work stops. That’s the protocol, and it’s non-negotiable. Colma has more than a million buried residents, and ground that was never formally mapped as a burial site can still hold remains or vault remnants. If we encounter human remains or what looks like an old vault during excavation, we secure the area and notify the cemetery district and county coroner before any further digging. The project gets redesigned around the find if that’s what the agencies require. This is a cost and timeline risk unique to Colma, and we plan for it in our schedule from day one.
In Colma’s damp, foggy conditions, it usually is. Segmental retaining walls made from Tremron units are more tolerant of the settlement and hydrostatic pressure that saturated soil creates. Poured concrete cracks when the ground behind it moves. Segmental block flexes at the joints and drains through the face if detailed correctly. The catch is that the drainage behind the wall has to be done right, or you’ve built a wet wall that effloresces and rotates. That’s the part we focus on. Call (877) 752-3868 if you’re weighing segmental block against poured concrete for a Colma site. We’ll give you the straight read.
