CWS Construction in Redwood Shores, CA | Iron Beam Contractors
We provide Redwood Shores Home Remodeling with independent CWS window and sliding door service across the area, from one two-story stucco home to the next. The thing that makes CWS work different here isn’t the hardware, it’s the ground underneath it: bay fill and former salt ponds settle, and when they do, window frames go out of square in ways you won’t see ten minutes inland. Call (833) 756-5936 for a free estimate, and we’ll tell you exactly what’s happening before we touch a single frame.
Why Redwood Shores Residents Choose Us for CWS Service
We’ve been in and out of CWS Series 700 and 800 windows and CWS sliding glass patio doors in Redwood Shores long enough to know their habits. These units were installed by the hundreds during the 1980s and 1990s build-out of the planned developments, and they are now hitting the same age-related failures at roughly the same time. Nolan Driscoll and our crew have replaced fogged insulated glass units on north-facing elevations where the bayside fog keeps the seals working harder than they ever should, and we have rebuilt more bottom rails on CWS sliders than we can count. We’re an independent CWS service provider, which means we work for you, not the manufacturer. We use OEM CWS glass, sash, and hardware whenever it’s available, and when a profile has been discontinued or the factory lead time doesn’t work for a family living with a draughty slider, we spec high-quality aftermarket insulated glass units and rollers that meet or beat the original. Our CWS sales & service work is built on knowing which route makes sense for each specific failure.

Common CWS Construction Problems We Solve in Redwood Shores
- Fogged double-pane insulated glass on north-facing windows. Marine air off the bay keeps moisture cycling against the glass, and the constant thermal expansion and contraction breaks the seal. We replace the insulated glass unit itself when the sash and frame are still sound, which saves thousands over a full window replacement.
- Failed roller tracks and corroded bottom rails on CWS sliding doors. Lagoon-side patios and low-lying lots see winter ponding that sits against the track, and the salt in the bay air works on the aluminum. We replace rollers, rebuild or replace bottom rails, and re-set the track so the door actually slides again.
- Rotted or soft wood jambs and sills at original CWS vinyl units. Many original Redwood Shores installs were flashed with materials and details that did not anticipate this much moisture. When storm ponding wicks into the rough opening, the wood goes soft behind the vinyl. We pull the unit, repair or replace the jamb and sill, re-flash properly, and re-install.
- Perimeter air and water infiltration from settlement. Bay-fill ground settles unevenly, and when it does, CWS frames get pulled out of square. The weatherstripping no longer meets, and you feel the draft or see the water streak. We check the rough opening before we order anything, because a square replacement unit in a skewed opening still leaks.
- Warped or binding sashes on two-story stucco homes. The afternoon sun on the west-facing elevations heats the vinyl unevenly, and twenty-year-old CWS sashes warp enough to bind in the track. We rebuild or replace the sash and adjust the balance system so the window opens and stays open.
CWS Service in Redwood Shores: What Local Conditions Mean for Your Equipment
Redwood Shores sits on bay fill and former salt ponds, and that changes everything about how CWS windows and sliders age. Foundation settlement here is not a rare defect; it is the baseline condition. When the slab moves, the rough openings move with it, and the window frame follows. So before we order any CWS replacement unit, we check plumb and level on the rough opening and look for slab moisture at the threshold. In the Shorebird and Pelican Cove areas around Redwood Shores Parkway, we routinely find original CWS sliders that are not square by an eighth of an inch or more. That does not sound like much, but it is enough to kill weatherstripping contact and let marine air in. It also means a simple pull-and-replace with the same size unit will fail again in a few years, because the opening is still out of square. We shim, re-flash, and set the new unit to the corrected plane. If the structure makes sense on paper, it’ll hold in the field. If it doesn’t make sense on paper, we fix it before we touch a beam.
CWS Models & Products We Service in Redwood Shores
We work on the full range of CWS units still in service across Redwood Shores: Series 700 and 800 vinyl single-hung and double-hung windows from the original 1980s and 1990s builds, CWS sliding glass patio doors on two-story stucco homes, vinyl retrofit replacement windows from the 2000s remodels, and the aluminum-clad and vinyl sliders found on townhome elevations around the office campuses. When OEM CWS glass and hardware are available, that’s our first call, because the match is clean and the warranty path is straightforward. When a CWS profile has been discontinued or the lead time stretches into months, we source high-quality aftermarket insulated glass units, rollers, and balances and install them to the same standard. Nolan will tell you plainly when a fogged unit is a seal repair and not a replacement. That honesty is the point.

AfterCWS Service Pricing in Redwood Shores
Here’s what you can expect to budget for our CWS-related work in Redwood Shores. A small repair, like replacing rollers or resealing a sash, sits at the lower end of these ranges. A full replacement with new construction or retrofit methods, especially on a settled opening that needs shimming and re-flashing, lands higher. Impact window installation runs more because the laminated glass and heavier frames cost more, period. A home addition is a different scale of work entirely, and it often triggers our General Contractor in Redwood Shores to manage Redwood City shoreline permits and BCDC review when you’re near the lagoon or bay. Every free estimate includes a written line-item quote, so you see the cost before you commit.
| Service | Price Range |
|---|---|
| Window Replacement | $4,500 – $15,000 |
| Impact Window Installation | $8,000 – $25,000 |
| Home Addition | $45,000 – $130,000 |
Call (833) 756-5936 to schedule a free estimate, and we will measure, assess the opening, and give you a number that holds. No vague allowances, no change orders hiding in the fine print.

FAQs – CWS Construction in Redwood Shores
No, we are an independent CWS service provider. We are not affiliated with or authorized by the manufacturer. That means we answer to you, not to a factory quota or a dealer network. Our recommendations on OEM parts versus high-quality aftermarket options are based on what’s best for your home, not on what a manufacturer mandates from its channel.
We use OEM CWS glass, sash, and hardware where it’s available and makes sense for the project. When a CWS profile has been discontinued, or the factory lead time would leave a Redwood Shores home exposed to bay air for months, we source high-quality aftermarket insulated glass units and rollers and install them to the same specification. You’ll know which route we are using and why before we order anything.
Most single-unit repairs, like a fogged glass swap or roller replacement, are done in one visit. A full retrofit window replacement across multiple openings typically takes two to five working days, depending on how much shimming and re-flashing the settled openings require. A home addition is a months-long project. We will give you a schedule with the estimate, and we hold to it.
We service CWS Series 700 and 800 vinyl single-hung and double-hung windows, CWS sliding glass patio doors, CWS vinyl retrofit replacement windows, and CWS aluminum-clad and vinyl slider units on townhome elevations. If you’re not sure what you have, send us a photo of the window label or the hardware, and we’ll tell you.
Window replacement in Redwood Shores runs $4,500 to $15,000 depending on the number of openings, the frame condition, and whether settlement has pulled the rough opening out of square. Impact window installation runs $8,000 to $25,000. Call (833) 756-5936 for an exact quote, the estimate is free and you’ll get a written line-item price.
