CWS Door Replacement in San Antonio: What to Know First

We’re an independent CWS service provider in San Antonio, and we replace CWS doors on a typical turnaround of one to three days once parts land. Most CWS door replacement work in San Antonio runs between $480 and $1,850 depending on slab versus full-frame replacement, glass package, and hardware. This page is for CWS owners who want straight answers about their door failure, what it actually costs, and whether the frame can be saved.

Call (903) 488-7019

If you’re standing in front of a CWS door that won’t close square or has fogged glass you can’t see through, call (903) 488-7019 and we’ll talk through what you’re seeing.

How CWS Products Fail – and How We Fix Them

• Warped slab on CWS 6400-series swinging patio doors. San Antonio’s July heat pushes surface temps past 140°F on west-facing exposures. The 6400’s slab can deflect enough that the sweep catches the threshold and the deadbolt no longer aligns. We check slab flatness with a straightedge before quoting replacement – if the frame is still square, a new slab drops in. If the frame pulled too, it’s a full-tear out. We’ll show you the measurement so you’re not replacing parts you don’t need.
• Seal failure between CWS insulated glass panels. When a CWS door’s glass fogs between the panes, it means the perimeter seal has failed. Moisture is inside the IGU. The fix is replacement of the glass unit or the slab itself, never scraping or re-sealing. We match Low-E coatings and grid patterns to the original CWS spec so the new pane doesn’t look like a patch.
• Roller degradation on CWS sliding door tracks. CWS sliding doors ride on steel-wheel rollers that eventually grind flat against aluminum track. The symptom is a door that feels like it’s dragging sand, then binds halfway. On CWS sliders, we’ll replace worn rollers with OEM where available or a quality aftermarket equivalent we’ve tested on San Antonio’s dusty limestone soil. Replacing rollers before the track grooves too deep saves you from a new frame.
• Threshold leaks around CWS entry doors. We see CWS entry doors in older San Antonio homes where the threshold pan was set without an effective sill pan flashing. Water that gets past the wooden buck wicks up into the stucco and rots the rough opening from the inside out. Our fix includes the door replacement plus a proper sill pan and backer rod, not just a tube of caulk.
• Frame rot at the bottom corners of CWS hinged patio doors. CWS frames spec aluminum with a thermal break. When that break fails near the sill, condensation collects at the corner joint and the frame corrodes from within. You’ll notice a white powdery oxidation or a soft spot at the bottom corner. This is a frame-level failure – we replace the entire unit and flash it so the new one doesn’t inherit the same problem.

Our CWS Door Replacement Process

1. 1
   The call and the conversation. You call (903) 488-7019. We ask what you’re seeing: sticking, fogging, leaks, drag. Sean Mackey or one of our senior techs walks through the CWS failure we suspect so you know what to expect before we even show up.
2. 2
   The on-site diagnostic. We measure slab flatness, frame square, roll function, and glass seal status. We check the rough opening for hidden water damage. Then we give you a written price before any work starts – a hard number, not a range that changes at the door.
3. 3
   The parts call. We source OEM CWS parts where they’re actually available. If the factory line is discontinued or the lead time is obscene, we tell you honestly and offer the aftermarket option we’ve vetted. You decide. No one sells you a surprise.
4. 4
   The replacement. We remove the old door, address any rough-opening rot or missing flashing, and set the new CWS-or-equivalent unit with continuous shims and a proper sill pan. We seal every penetration and trim the exterior so it drains.
5. 5
   The test. We run the door through full open-close cycles, check the deadbolt throw, test the sweep contact, and verify the glass is seated clean. We hand you photos of everything we did.
6. 6
   The guarantee. Your replacement carries our 365-Day Done Right Promise. If it’s not done right, we make it right – 365 days, parts and labor, in writing.

What CWS Door Replacement Costs in San Antonio

Honest numbers, because you shouldn’t have to call us just to know if this is a $500 problem or a $2,000 problem.

• Slab-only replacement (new door panel, existing CWS frame): $480 to $900
• Full-frame CWS patio door replacement: $950 to $1,450
• CWS entry door with new frame and re-flash: $780 to $1,400
• Full-frame CWS sliding door with Low-E glass: $1,100 to $1,850

What moves the price: whether the CWS frame is still alive, the size of the rough opening, whether we’re replacing one lite or the whole slab, and the glass package (standard clear, Low-E, or impact-rated). A full-frame replacement is always pricier than a slab because we’re disassembling the rough opening, correcting framing, and re-flashing everything.

Every project gets a free, written, line-item estimate before we order anything. Call (903) 488-7019 and we’ll quote your exact CWS door in San Antonio.

Why San Antonio Homeowners Call Juniper Windows San Antonio for CWS Work

We’re the windows-and-doors shop, not a general remodeler with a door guy on the side. If your CWS door failed because the original install skipped a flashing step, we catch it. If the frame is too far gone, we’ll tell you before we quote the part. If a repair we made doesn’t hold, the second visit is free – no charge, no argument.

We also carry multiple lines so you’re never cornered into one option: PGT, CGI, ES Windows, and ECO Window Systems all sit alongside CWS. That matters when a CWS part is backordered and you don’t want to wait three months for a door that seals. We’ll present the alternatives in plain language and let you pick.

If the numbers don’t make sense on paper, they won’t make sense on your wall either.
