Mr-Glass Custom & Geometric Windows in Los Angeles: What to Know First
Mr-Glass custom and geometric windows in Los Angeles – arched tops, radius corners, trapezoids, oversized fixed panes – are typically serviced within 5 to 10 business days from our first measurement visit. Most repairs on these units run $380 to $1,400 depending on the shape, glass type, and whether the sash or frame needs work, and you’ll have a written price before we lift a tool. This page is for homeowners in Los Angeles who own Mr-Glass specialty windows and want a straight answer on what’s wrong, what it costs, and who can fix it without voiding the warranty. Call (509) 265-6387 and we’ll start with a measured survey you keep.
As an independent Mr-Glass service provider, we’re not authorized by or affiliated with the manufacturer. We service their products because we know the lines, the failure patterns, and what Los Angeles sunlight does to a geometric unit over five to ten years. Sonia Raman, our owner, has been measuring and setting custom openings across Los Angeles County for the better part of two decades, and she built this company on the principle that the measurement and the written quote are the same document.
How Mr-Glass Products Fail – and How We Fix Them
Geometric windows fail differently than standard rectangles. The stress concentrates at the corners and along the radius cuts, and Los Angeles temperature swings between inland heat and coastal marine layer do the rest. Here’s what we see on Mr-Glass units in this market:
- Radius corner seal separation on Mr-Glass Geometric Series fixed units. The bent-glass corners on shaped units – arches, half-rounds, quarter-rounds – carry more sealant stress than flat edges. After five to seven years of Los Angeles sun, the butyl seal at the apex of an arch can lose adhesion, letting moisture between the panes. You’ll see a milky fog that never clears, starting at the top curve. We remove the sash, isolate the failed IG unit, and replace with a new sealed unit cut to the exact radius – not a caulk patch that hides the problem for one season.
- Frame racking on oversized Mr-Glass Custom Impact windows. Mr-Glass impact-rated units are heavy, and when they’re specified in widths beyond 72 inches, the frame can deflect slightly if the rough opening wasn’t reinforced to spec. In neighborhoods like Sherman Oaks and Studio City where mid-century homes get retrofitted with big fixed glass, we regularly find sagging headers causing the operable sash to bind. Our fix starts with a frame reading – we measure the diagonal and level before touching the glass – then shim and re-anchor the frame, or replace the header support if the structure’s the culprit.
- Condensation between panes on Mr-Glass Arched Series transoms. Arched transoms over entry doors take direct afternoon sun on west-facing walls in Los Angeles. The solar load breaks down the desiccant inside the spacer bar faster than on shaded windows. When the desiccant’s spent, humidity inside the airspace condenses on the glass. It’s a sealed unit replacement, not a repair. We order a matching new IG unit with the same Low-E coating and spacer color, so the replacement doesn’t read as a patch from the street.
- Hardware wear on Mr-Glass casement and awning geometric units. Geometric casements – especially triangular and pentagon-shaped vents – use multi-point locking hardware that other brands don’t carry. When the crank operator strips or the locking points fall out of alignment, you’ll feel the handle go loose before the lock catches. We replace with OEM hardware where the unit’s still under warranty, and quality aftermarket equivalents that match the screw pattern when it’s not. The key is keeping the original geometry: a misaligned replacement operator will crack the sash corner over time.
- Perimeter flashing failures on Mr-Glass custom trapezoid windows. Trapezoids and angled units create awkward flashing intersections, especially on stucco exteriors common across Los Angeles. Water finds the low corner where the sill pan meets the angled jamb. We pull the trim, inspect the pan, and rebuild the flashing with new adhesive membrane before resetting the unit. It’s the kind of repair that looks done from the outside but fails from the inside if the pan’s not right.
Our Mr-Glass Custom & Geometric Windows Process

- 1
Call and schedule the measured survey. You call (509) 265-6387. We schedule a visit, and a live person answers the phone – 24/7, not a callback queue. You’ll know who’s coming and when.
- 2
On-site diagnostics and measurement. Our technician arrives in uniform, background-checked, and identified by license number before setting foot on the property. We measure the unit, the rough opening, the diagonal, the sightlines, and the existing glazing specs. You keep a copy of that survey.
- 3
Written scope and price. We hand you a written quote before any work starts. It specifies the part number or fabricated part dimensions, OEM versus aftermarket, the labor, and the warranty on our work. That written price does not change once we begin – Haven Clause 1 is the whole point of how we operate.
- 4
The repair or replacement. We remove the sash or the entire frame as the job requires, install the new IG unit or hardware, and rebuild flashing or seals where needed. Every step respects the original geometry of the window.
- 5
Testing and documentation. We check the unit for alignment, seal integrity, and smooth operation. You get a documented photo record of the work, before and after, as standard evidence – not an upsell.
- 6
365-Day Done Right Promise. If the repair doesn’t hold, we make it right. That’s written into the Haven Standard, not a verbal assurance.

AfterWhat Mr-Glass Custom & Geometric Windows Costs in Los Angeles
Here’s what we charge for common Mr-Glass custom and geometric window repairs in Los Angeles. These are real numbers, not ranges that expand once we’re in the door:
| Scenario | Typical Cost |
|---|---|
| Stuck or stripped casement/awning crank operator replacement | $185 – $340 |
| Fogged IG unit replacement (arched or radius top, up to 36″ x 48″) | $420 – $780 |
| Fogged IG unit replacement (oversized custom fixed, 60″ – 96″) | $900 – $1,800 |
| Full geometric sash replacement (shaped unit, standard glazing) | $1,200 – $2,600 |
| Flashing and sill pan rebuild on a trapezoid or angled unit | $380 – $750 |
| Full frame replacement on an impact-rated geometric window | $2,800 – $6,500+ |
What moves the price: the glass size and shape (radius cuts cost more to fabricate than straight edges), whether the unit is impact-rated, whether the frame needs stripping or can stay in place, and access – a second-story arch over a stairwell takes longer than a ground-floor trapezoid. You’ll get the written line-item price before work starts. Call (509) 265-6387 and we’ll schedule the free estimate.
Why Los Angeles Homeowners Call Sightline Windows & Doors for Mr-Glass Work

We’re not the cheapest in Los Angeles, and we don’t try to be. We’re the installer that hands you the written price before a tool is lifted – the measurement and the quote are the same document, and that’s been true for every one of the 18,000+ openings we’ve touched since 2012. When a Mr-Glass geometric unit fails, you can call us and get a technician who knows the line, knows the Los Angeles climate reality, and will tell you straight whether a repair makes sense or a replacement is the better dollar. If a replacement’s the call, we specify across eight manufacturer lines – PGT, CGI, CWS, ES Windows, and others – by performance tier and price range, not by margin. And if we quoted you a repair and the fix doesn’t hold within 365 days, the Done Right Promise means we come back and make it right. That’s the standard we work under. It’s named, it’s written, and we’ve never treated it as a courtesy.
FAQs
No, not when the repair is done correctly with appropriate parts. If your Mr-Glass unit is still under the manufacturer’s warranty, we use OEM hardware and IG units where the warranty requires it. If it’s out of warranty, we’ll specify quality aftermarket equivalents that match the original specs – and we’ll tell you which we’re quoting and why before you decide.
Yes. We measure the existing glazing – the glass thickness, the Low-E coating type, the spacer color, the tint – and order a new IG unit made to those specs. The goal is a replacement that doesn’t read as a replacement from the street, especially on a visible front-facing arch or oversized fixed pane in Los Angeles where the light hits it all day. Call (509) 265-6387 for an exact quote on your unit.
For standard arched and radius shapes, the glass fabricator typically turns the new IG unit in 5 to 10 business days. Complex geometry, unusual tints, or impact-rated glass can extend that to 2 to 3 weeks. We’ll give you a written timeline when we hand you the price, and it updates if the fabricator’s schedule shifts. The survey, the quote, and the schedule are all in writing – that’s the standard.
If the frame is sound and the failure is a fogged IG unit or worn hardware, repair is almost always the better dollar – typically $420 to $1,800 versus $2,800 to $6,500+ for a full frame replacement on a shaped or impact-rated unit. If the frame is racked, the flashing has been leaking for years, or the geometry of the rough opening was never right, replacement may be the honest call. We’ll show you the frame readings and the written scope so you can decide with numbers, not a sales pitch. Call (509) 265-6387 to schedule a free measured survey.
Measure once, write it down, then measure again. That’s how we start every Mr-Glass job in Los Angeles, and it’s why the written price you get is the price you pay.
