CGI Construction in Moss Beach, CA | Ashford Contractors
We provide independent CGI service across Moss Beach, from exterior siding and trim assemblies to deck systems and coastal re-sides. We also serve CGI in El Granada and the broader San Mateo coast. The thing that sets our CGI work here apart is that we treat every job as a moisture and corrosion investigation first, because Moss Beach’s salt fog punishes fasteners, flashing, and hidden framing in ways inland contractors never see. If you’re looking at CGI repairs or a full re-side in the 94038 area, call (877) 752-3868 and we’ll come look at it properly.
Our team has spent years rebuilding CGI-clad exteriors along the San Mateo coast. We’re not manufacturer-affiliated, and we’ll tell you that up front. What we are is a full-scope general contractor that knows CGI sales & service from the substrate out, so when we quote a repair we’re quoting what’s actually behind the panel, not just what you can see from the driveway.
Why Moss Beach Residents Choose Us for CGI Service
Most contractors approach CGI work as a surface problem: replace the board, caulk the joint, paint it, done. That approach fails early in Moss Beach. Glen Mossier, our owner, trained in framing and mechanical systems at Skyline College in San Bruno, and he’s spent two decades pulling apart coastal assemblies to see how they actually fail. What he’s taught our crew is simple: read the system from the back side out. Check the flashing, check the fasteners, check the sheathing, then quote. That’s the only way a CGI job survives here.
We carry stainless and copper flashing and fasteners sized for coastal exposure, and we keep OEM-matched CGI trim and accessory profiles on our order list where they’re still made. For older CGI lines where the OEM parts are gone, we source quality aftermarket stock and we tell you exactly what we’re using and why. You get a straight answer, a written line-item quote, and a crew that doesn’t cut corners on what’s hidden behind the siding.

Common CGI Construction Problems We Solve in Moss Beach
- Salt-fog corrosion on fasteners and flashing. Galvanized screws and cut-edge steel flashings pit and bleed rust within a few seasons on the ocean-facing side of town. We routinely find CGI trim that looks fine but is held on by fasteners that crumble when touched. We spec stainless or copper from the start.
- Fog-driven moisture trapped behind CGI panels. Wind-driven rain off the Pacific gets past caulk joints and sits against wood sheathing. Panels look fine from the street, but behind them the framing is spongy and mold-stained. We open up suspect sections before quoting anything.
- Paint and finish failure on trim and fascia. Persistent wet-dry cycling on salt-laden air chalks and peels CGI trim edges long before interior surfaces show any problem. If the substrate is sound, we repair and recoat. If it’s not, we replace and re-detail.
- Deck ledger and guard deterioration. The back side of ledgers and hidden fastener lines at guard posts rot from constant damp. Decades-old unpermitted decks in Moss Beach often hide this until railings get loose, which is a safety issue that can’t wait.
- Unpermitted additions with failing CGI cladding. A lot of older coastal cottages here were added onto informally over the years, and those additions often got whatever siding was handy. We inspect the framing behind the CGI, correct what’s rotted or undersized, and re-clad to current coastal code.
CGI Service in Moss Beach: What Local Conditions Mean for Your Equipment
Moss Beach sits directly on the San Mateo coast fog belt, where salt-laden marine air and wind-driven rain attack every exterior assembly. This changes what CGI service actually means here. On the ocean-facing side of town, constant salt fog keeps surfaces wet for long stretches, so even newer galvanized flashings and fasteners fail years ahead of inland schedules. We’ve seen galvanized flashing on a four-year-old re-side already pitted through, while the same spec in San Mateo or CGI in Half Moon Bay inland would run another decade without complaint. That’s why every CGI re-side or roof detail we quote in Moss Beach starts with a stainless-or-copper spec and a look at the back side of the deck ledger, not just the visible face.
We also work around the housing stock here. Moss Beach has older coastal cottages and mid-century homes with wood siding, older decks, and unpermitted additions from decades of informal building, plus newer custom homes on infill lots. Every one of those situations demands different detailing. A mid-century home with original CGI and a fog-exposed west wall needs a full moisture investigation before we touch the cladding. A newer infill build might just need corroded fasteners swapped and trim re-sealed. Knowing which situation you’re standing in front of is what separates a real repair from a patch job that fails in three years.
CGI Models & Products We Service in Moss Beach
We service CGI exterior siding and trim assemblies in both fiber-cement and composite lap and panel profiles, along with CGI deck and railing systems including fascia, ledger, and guard components. That covers the CGI flashing, fascia, and soffit trim packages used on coastal re-sides, plus the CGI window and door trim surrounds common on mid-century and infill-lot replacements in Moss Beach.
For parts, we spec OEM-matched trim and accessory profiles wherever the manufacturer still makes them, and we stock common stainless fasteners and copper flashing locally so a Moss Beach repair doesn’t wait on a freight order. When an OEM profile has gone obsolete, we use a quality aftermarket match and we tell you that’s what we’re doing, with the option to upgrade the detail while we’re in there. We also handle Moss Beach service area roof repair and metal roofing, which often ties directly into the flashing and fascia work a coastal CGI job needs.

AfterCGI Service Pricing in Moss Beach
Pricing for CGI-related work in Moss Beach depends on what we find when we open the assembly up. A simple repair with sound framing runs on the lower end; rotted sheathing, ledger replacement, or a full re-detail with copper flashing pushes the number up. Here are the price ranges we work within for the roof and exterior scopes that most often accompany CGI service here:
| Scope | Typical Range |
|---|---|
| Roof Repair | $400 – $1,800 |
| Roof Replacement | $8,000 – $20,000 |
| Metal Roof Installation | $15,000 – $40,000 |
| Standing Seam Metal Roof | $15,000 – $40,000 |
Those numbers shift with roof size, pitch, tear-off conditions, and how much of the flashing and fascia needs re-done in stainless or copper. Call (877) 752-3868 and we’ll give you a written line-item estimate after we’ve actually looked at the job. Estimates are free.

FAQs – CGI Construction in Moss Beach
Start with the framing behind the CGI, especially on the addition’s exterior walls and any deck ledger attached to them. Unpermitted coastal additions in Moss Beach often have undersized framing, no flashing at the CGI-to-foundation transition, and hidden rot where fog-driven rain has been getting in for years. We’ll open a few strategic sections, check the sheathing and fasteners, and tell you whether you’re buying a re-clad or a rebuild. Call (877) 752-3868 and we’ll do that inspection before you close.
No, and we’re upfront about that. Ashford Contractors is an independent Moss Beach General Contractor. We service, repair, and re-side with CGI products, but we have no manufacturer affiliation. That independence means we spec the right material for the coastal conditions, not the product with the best rebate.
OEM first, always, where the manufacturer still makes the trim, accessory, or panel profile you need. For older CGI lines where the OEM parts are gone, we use quality aftermarket stock and we tell you exactly what we’re spec’ing and why. On coastal jobs, we upgrade fasteners and flashing to stainless or copper regardless of what the original spec called for.
A targeted repair with sound framing is usually one to three days. A full re-side with framing correction, re-flashing, and trim runs longer, especially if weather windows force us to work around the fog and wind. We give you a schedule with the written estimate, and we don’t quote weather-dependent work we can’t stand behind.
For a small to mid-sized repair with sound framing, expect $400 to $1,800 depending on how many sections we open and how much flashing gets replaced in copper or stainless. If the rot has spread into the sheathing, the scope shifts into a re-side and the number goes up accordingly. Call (877) 752-3868 and we’ll put a real number on it, not a guess.
