Why San Francisco Homeowners Choose Unilock Construction
We provide Unilock in San Francisco, repairing and installing paver driveways, patios, and walkways across neighborhoods from the Outer Sunset to the Richmond District. Our crews work on Unilock systems every week, which means we know how this city’s sandy soil, seasonal fog, and seismic settling affect the product in ways a pop-up installer never sees. We are not a Unilock dealer or authorized installer, but we stock common Unilock replacement pavers locally and source genuine units for larger repairs.
What separates our Unilock work from the rest is not a slogan. It’s the written price you receive before any work starts, the drop cloths and shoe covers on every visit, and the 365-Day Done Right Promise that covers every completed project. If something isn’t right after we leave, we come back and make it right. Call us at (831) 480-4497 for a free estimate on Unilock paver work in San Francisco.
Why Trust Elmstead Remodeling San Francisco for Your Unilock Construction?
Elmstead Remodeling San Francisco, a Cedarwell company, has been serving families across San Francisco for years. Graham Stein, our owner, learned the trade at Los Angeles Trade-Technical College and has spent nearly three decades running crews across California before building our San Francisco team. He’s the one who writes out every cost before a single tool touches the floor, and he’s the one who sets quiet hours so families aren’t chased out of their own homes during a paver project.
When it comes to Unilock specifically, our technicians handle Eco Dublin, Brussels Block, Courtstone, and Richcliff product lines regularly. We keep common Unilock replacement pavers and edge restraints in stock so most driveway and patio repairs don’t wait on shipping. For anything larger, we source genuine Unilock units directly. This means you’re not getting a substitute product that looks vaguely similar; you’re getting the actual paver that matches your existing installation, with the same dimensional tolerances and color blend. And we always use commercial-grade aggregates and polymeric sands for sub-base and joint work, materials that match or exceed OEM specifications for San Francisco’s soil conditions.
Every project runs through the Cedarwell Care Promise, which names exactly what the crew will protect and how: drop cloths on the floors, shoe covers at the door, a photo of the clean-up before the crew leaves, quiet tools during rest hours where possible, and pet-safe product choices where there is a choice.

Common Unilock Construction Problems We Fix in San Francisco
- Rusted or failed edge restraints on Courtstone and Brussels Block driveways. San Francisco’s ocean air accelerates corrosion on steel or low-grade plastic restraints, especially in coastal districts like the Outer Sunset and the Richmond. When the restraint lets go, pavers drift outward, gaps open up, and the whole edge starts to unravel. We replace failed restraints with heavy-gauge aluminum, which holds its shape through years of damp, salty air.
- Low spots and settling across paver patios and driveways. The sandy, loosely compacted soil under many pre-1940 San Francisco homes settles unevenly, especially after heavy winter rains saturate the ground. Unilock pavers shift, low spots form near drains, and water pools instead of running off. We recompact the base with a plate compactor and re-level the affected area, which fixes the rut without tearing out the whole installation.
- Cracked or chipped pavers from vehicle turning stress. In narrow San Francisco neighborhoods, driveways often double as turning zones for delivery trucks and even Muni buses. We see cracked Courtstone units along drive edges where the turning radius cuts tight. We pull the affected rows, replace the broken pavers with matching units, and reinforce the edge so the next bus doesn’t do the same damage.
- White efflorescence staining on pavers near the ocean. Salt air and consistent fog leave mineral deposits on Unilock surfaces, especially on Richcliff and Eco Dublin with their textured faces. The white haze is not paver failure; it’s mineral salts wicking through the concrete. We clean the surface with appropriate cleaners and, where needed, reapply joint sand that’s been washed out by coastal moisture.
- Joint sand washout from San Francisco’s rainy winters. Fog drip and winter storms slowly flush polymeric sand from between pavers, leaving joints open to weed growth and paver movement. We re-sweep and re-activate commercial-grade polymeric sand that locks up tight against the next wet season, which keeps pavers stable and keeps the weeds out.
Unilock Parts & Our Repair-vs-Replace Approach
We stock common Unilock replacement pavers and edge restraints in San Francisco so most paver driveway and patio repairs can start the same week we diagnose the problem. For larger repair jobs, we order genuine Unilock units directly. We don’t substitute look-alike pavers because dimensional variation and color drift show up immediately on a driveway that gets afternoon sun.
For sub-base and joint work, we use commercial-grade aggregates and polymeric sands that meet or exceed OEM specs. These are not bargain-bin materials; they’re selected for San Francisco’s sandy soil, seasonal rain, and the constant moisture fog brings. We recommend full driveway or patio replacement only when base failure is beyond local recompaction. If the base is sound and the problem is surface-level, we repair the paver system and save the family thousands of dollars versus a full teardown. Call (831) 480-4497 if you’re not sure whether your Unilock system needs repair or replacement; we’ll tell you straight.
Our Unilock Service Process – Step by Step
- 1
Diagnosis and written price. Our technician walks your paver driveway, patio, or walkway, identifies the specific Unilock product line, inspects edge restraints, joint sand, and base compaction, and writes out a line-item price before any work begins. You’ll know exactly what the repair involves and what it costs, with no change orders appearing after the crew arrives.
- 2
Repair or installation. We lay drop cloths, put on shoe covers, and set quiet hours before tools come out. The crew pulls damaged pavers, replaces edge restraints where needed, recompacts the base with a plate compactor, and installs matching Unilock units with commercial-grade joint sand. For full paver driveway or patio installations, we build the base up properly for San Francisco’s soil from day one.
- 3
Testing and clean-up. We run the surface for drainage, check edge stability, and make sure joint sand is locked in place. Then we photograph the clean-up before the crew leaves, so you have proof the site was left right.
- 4
Warranty. Every completed project carries the 365-Day Done Right Promise. If it’s not done right, we make it right. That’s the whole promise.

We Also Service These Brands
While this page covers Unilock, our General Contractor services also include KraftMaid and Wellborn cabinets, Cambria and Silestone countertops, and Kohler fixtures.

FAQs – Unilock Construction Service in San Francisco
No. We are an independent Unilock service provider in San Francisco, not a Unilock dealer or authorized installer. That independence means we can repair or install Unilock paver driveways, patios, and walkways using genuine Unilock units without pushing a dealership’s inventory or markup. Our crew sees Unilock systems every week, so we know the product lines and failure points intimately.
Yes. We stock common Unilock replacement pavers and edge restraints locally, and we source genuine Unilock units for any large repair. For sub-base and joint materials, we use commercial-grade aggregates and polymeric sands that match or exceed OEM specifications. You’re getting the actual paver product you already own, not a generic substitute that doesn’t match the color or dimensions.
Most single-area repairs, like replacing cracked pavers or failed edge restraints, take one to three days depending on scope and San Francisco weather. Full paver driveway or patio installations typically run one to two weeks, including base preparation, compaction, and joint sand activation. We’ll give you a written timeline with your price so there’s no mystery about how long the crew will be at your home. Call (831) 480-4497 to schedule a free estimate and get a specific timeline for your Unilock project.
We service and install Eco Dublin, Brussels Block, Courtstone, and Richcliff product lines. If you have a different Unilock series, call us; we can source genuine units for any line the manufacturer currently produces, and we’ll confirm before scheduling. Our local stock covers the models most common in San Francisco driveways and patios.
Using an independent contractor does not void your Unilock product warranty. We use genuine Unilock replacement pavers and materials that meet or exceed OEM specs precisely so your warranty stays intact. What voids a warranty is a botched installation or the wrong sub-base material, not the contractor’s authorized status. We build every repair and installation to the manufacturer’s specifications so you keep the coverage you paid for.
Unilock paver work in San Francisco typically falls within these ranges:

Every project gets a written, line-item price before any work starts, so the number you see is the number you pay. Call (831) 480-4497 for an exact quote on your Unilock paver repair or installation in San Francisco.
Yes. If your pavers are a current-production Unilock line like Courtstone, Brussels Block, Eco Dublin, or Richcliff, we can order matching genuine units. Color and dimensional match is reliable on current production lines. If your pavers are a discontinued series, we’ll discuss blending strategies or a full-row replacement approach that minimizes visible mismatch. Call (831) 480-4497 with a photo of your damaged area, and we’ll tell you what’s possible.
Low spots near a drain usually indicate the base under those pavers is washing out or compacting unevenly. In San Francisco’s sandy soil, winter rain and fog drip saturate the ground, and the fines in the base migrate out over time. Sweeping sand into the joints doesn’t fix the problem; it just fills the surface gap while the base keeps sinking. We lift the affected pavers, recompact the base with a plate compactor, and reset the units so drainage flows correctly. Call (831) 480-4497 and we’ll diagnose whether it’s a simple recompaction or a deeper base failure.
Yes, and this is one of the most common repairs we do in San Francisco. When edge restraints rust out or snap, the pavers at the edge drift outward and the whole installation starts to loosen. We can pull the affected edge pavers, install heavy-gauge aluminum restraints, reset the row, and recompact the edge without touching the interior of the driveway. It’s a focused repair, not a teardown. Call (831) 480-4497 for a written price on edge restraint replacement.
White stains are efflorescence, which happens when mineral salts wick through the concrete and crystallize on the surface. It’s common in San Francisco’s coastal neighborhoods where salt air and fog keep paver surfaces damp. For a simple cleaning, we apply a paver-safe efflorescence cleaner and rinse thoroughly. The condition usually diminishes over time, but recurring heavy deposits near the ocean may need periodic professional cleaning. Call (831) 480-4497 and we’ll recommend the right product and process for your specific Unilock surface.
It depends on the base. If the base is stable and the cracking is limited to surface pavers, we can replace the broken units, recompact settled areas, and re-sand the joints for a fraction of a full replacement cost. If the base has failed across a large portion of the patio, patching becomes a recurring expense and replacement is the honest recommendation. We’ll tell you which situation you’re in, and you’ll get a written price for either path before you decide. Call (831) 480-4497 for a free assessment.
