CWS Driveway & Pavers Nationwide

CWS Driveway & Pavers: The West Covina Owner’s Guide

CWS driveway and paver systems in West Covina typically cost $7,000 to $18,000 for full paver driveway installation, with repairs to failing sections running $250 to $700 for sealing or resurfacing depending on the damage. We stock CWS-compatible pavers, edge restraints, joint sand, and base materials on our trucks and can have a crew out to your property within a couple of days for an assessment. Most West Covina homeowners discover a failing paver system the way you probably did: a sunken section near the garage apron, shifting pavers that rock underfoot, or joint sand washing out after every rain and leaving gaps where weeds push through.

Which CWS Models This Applies To

CWS driveway and paver systems come in three primary paver thicknesses: 60mm for pedestrian patios and walkways, 80mm for residential driveways, and 100mm for heavy vehicle or commercial-grade applications. The 80mm residential paver is what we see on most West Covina driveways, and it has a specific interlock profile that does not mate correctly with pavers from other manufacturers. Here is the compatibility gotcha: mixing a CWS paver with a generic paver of the same nominal size will leave a visible seam and a weak point at the joint because the spacer lugs sit at different positions. If you are patching a section, we match the original CWS profile. If the original is discontinued, we can often source it through our supplier network or cut a matching section from a compatible profile and document the transition for you. We are an independent service provider, not affiliated with CWS, which means we give you an honest read on whether an aftermarket equivalent will hold up or whether you should stick with the original spec.

Signs Your CWS Driveway & Pavers Are Failing

• Sunken or low spots near the garage apron. This is almost always a base failure, not a paver failure. In West Covina, we deal with clay-heavy soil that expands and contracts with moisture, and a base that was never compacted in lifts will settle unevenly. The pavers drop with it, and the fix means pulling the section, rebuilding the base, and relaying the pavers.
• Pavers rocking or shifting under foot traffic. This usually means the edge restraint has failed or was never installed. Without a solid edge, the interlock loosens and pavers migrate outward, opening joints. We see this most on driveways where the restraint is a thin plastic strip instead of a concrete haunch.
• Joint sand washing out after every heavy rain. West Covina gets short, intense downpours, and if the joint sand is not a polymeric or stabilized product, it will wash down the slope toward the street. Once joints stay empty, pavers lose lateral support and the whole surface starts working loose.
• Efflorescence or white haze that keeps coming back. This is mineral staining from moisture moving through the paver, and it is common on CWS concrete pavers in our area. It is cosmetic, not structural, but it signals that water is not draining away from the surface as it should. A good sealer and a drainage check usually corrects it.
• Cracks or spalling on individual pavers. Spalling on the surface is often from salt exposure if you have salted the driveway in winter, or from repeated hot-cold cycling here in the San Gabriel Valley. Cracked pavers are cheap to swap individually, but if you are seeing cracks across many pavers, the base has moved underneath and you are looking at a section rebuild.

Replacement Cost & What’s Included

For a full paver driveway replacement in West Covina, expect $7,000 to $18,000. The spread comes down to square footage, access, base condition, and whether you are matching a CWS-specific paver profile or starting fresh with a new design. A smaller driveway under 400 square feet with good existing base runs near the bottom of that range. A long driveway with a failed base, a slope, or drainage work needed runs toward the top. Every quote from us includes line items for demo and haul-off of the old material, base excavation and compaction, edge restraints, the pavers themselves, joint sand, and labor. That is the part we insist on: you get a written price before any work starts, and the number on that paper is the number you pay. No change orders unless you ask for something different mid-job, and no surprise invoices at the end. The work is covered by our 365-Day Done Right Promise, which means if anything is not right within a year of completion, we come back and fix it at no cost to you.

DIY or Call Us?

There are a few checks you can do without touching a tool. Walk the driveway and mark every paver that rocks or sounds hollow when you tap it with a rubber mallet. Check the edges where the driveway meets lawn or soil and look for gaps where pavers are drifting outward. And after the next rain, watch where water pools: standing water on pavers is a drainage problem, not a paver problem, and fixing it starts with the base. What you should not do is pull and reset pavers on a failed base and expect it to hold. Without recompacting the base in lifts and re-establishing proper slope, you will be back to the same sunken, shifting surface within a season. If the base has failed, the fix is a section rebuild, and that needs compaction equipment and a crew who knows how to cut and relay the CWS profile without damaging the interlock. Give us a call at (707) 760-7579 and we will come out, assess what is actually failing, and give you a written price for exactly what needs to happen.
