Mr-Glass Home Additions & ADU: The Irvine Owner’s Guide

Mr-Glass home additions and ADU systems in Irvine typically run $45,000-$130,000 installed, depending on whether you’re extending an existing structure or building a detached unit from slab to roof. We stock Mr-Glass-compatible framing hardware, glazing channels, and weatherseal kits for same-day assessment, and we carry KraftMaid, Cambria, and Silestone lines for the interior finish work that usually follows the shell. Most Irvine owners first notice trouble when the thermal break seal fails between glass panels, or when the aluminum frame tracks start collecting condensation that stains interior drywall.

Which Mr-Glass Models This Applies To

Mr-Glass produces three primary series relevant to Irvine home additions and ADUs: the Residential 5000 Series (single-pane retrofit, common in 1980s-1990s Irvine tract expansions), the Thermal 7000 Series (dual-pane with integrated thermal break, used in most post-2005 additions), and the ProLine ADU Series (slim-profile frames designed for units under 800 square feet). The part you need depends on the etched code in the frame corner, not the invoice - the 5000 Series uses a 1.75-inch frame depth, while the 7000 and ProLine ADU both spec 2.25 inches but with incompatible glazing gaskets.

We’ve replaced 5000 Series thermal breaks in Northwood and Woodbridge homes where the original silicone edge seal hardened in the dry Santa Ana cycles, and we’ve swapped ProLine ADU header tracks in Portola Springs where the lighter frame gauge flexed under the weight of dual-pane low-E glass. OEM Mr-Glass parts ship from their Ontario, CA distribution center in 3-5 business days; we also source aftermarket equivalents from C.R. Laurence that match the 7000 Series thermal break spec at roughly 60 percent of OEM cost, though we won’t use them on load-bearing header assemblies. Bring your frame corner code or a photo of the etched label - we’ll tell you which path makes sense.

Signs Your Mr-Glass Home Additions & ADU Is Failing

• Fog between dual panes that won’t wipe away. The thermal break seal has failed, and the desiccant inside the spacer bar is saturated. In Irvine’s coastal-influenced climate, this usually starts at the south-facing edge where daily expansion cycles stress the sealant.
• Frame tracks that collect water or show white oxidation. The weep holes are clogged with construction debris or the sill pan flashing was omitted during original install. The aluminum oxidizes, the track swells, and the operable sash binds.
• Operable panels that stick, rattle, or won’t lock. The roller carriage wears unevenly when tracks deform, or the multipoint lock mechanism loses alignment. We’ve found this in Woodbridge second-story additions where summer heat expansion threw off the strike plate.
• Draft or temperature stratification near the glass. The compression seal has flattened past recovery, or the argon fill has leaked through a compromised edge seal. Your HVAC runtime increases before you notice the comfort problem.
• Visible separation of the glass from the frame edge. The structural silicone bond is failing - this is a safety issue, as the glass is no longer fully retained. We flag this immediately and temp-secure the panel before ordering parts.

Replacement Cost & What’s Included

The spread depends on three factors: access (second-story additions need scaffolding or interior protection), whether the original install included proper sill pan and head flashing (fixing someone else’s shortcut adds labor), and whether the interior trim is still available or needs custom matching. Under Clause 1 of the Haven Standard, you get the written price before we touch a tool - every line item listed, no category called “miscellaneous.” The 365-Day Done Right Promise covers the installation and the parts; if the seal fails or the track binds inside a year, we return and correct it at no charge.

DIY or Call Us?

There’s a safe middle ground here. You can check the etched frame code, photograph any fogging or separation, and confirm whether your weep holes are visible and clear - a straightened paper clip, gentle pressure, no disassembly. What you should not do: remove a fixed glass panel yourself (the suction cups rated for the weight cost more than our service call, and a dropped dual-pane unit is a serious laceration hazard), or attempt to re-bed a thermal break seal with consumer-grade silicone (the expansion coefficient is wrong for aluminum, and you’ll void any remaining warranty).

We carry 7000 Series gaskets and ProLine ADU roller sets on our Irvine trucks, and we can assess whether the problem is the part, the installation, or the structure settling around it. Call (657) 227-2502 - we’ll schedule a free estimate, bring the parts that match your frame code, and give you the written price before any work starts.
