Schluter Windows & Doors Nationwide

Schluter Windows & Doors: The Irvine Owner’s Guide

We stock and install Schluter-compatible windows and doors across Irvine, with most replacements quoted in the $4,500-$15,000 range for full window replacement and $8,000-$25,000 for impact-rated installations. Same-day assessment visits are available, and we carry common Schluter flashing membranes, Kerdi collar adapters, and prefabricated sill pans on our trucks. Most Irvine homeowners discover a Schluter window or door has failed when they spot water staining on drywall beneath a sill, feel a draft that wasn’t there last season, or notice the exterior trim pulling away from the stucco after Santa Ana wind cycles.

Which Schluter Models This Applies To

Schluter entered the window and door market through its Kerdi-Window and Kerdi-Door lines, integrated systems built around bonded waterproofing membranes rather than traditional flashing tape. We also service Schluter-compatible rough openings where Kerdi-Board or Kerdi-Flex membrane was used as the primary water barrier with third-party window units. To identify your exact system, check the interior jamb for a printed Schluter label (usually on the upper right corner of vinyl units) or measure the membrane overlap: Kerdi systems require a 2-inch minimum overlap at the sill, which is narrower than the 4-inch standard many competing membranes use.

The OEM-versus-aftermarket decision for Schluter is specific. Schluter’s Kerdi collar adapters and preformed sill pans are proprietary in dimension, their ⅜-inch bonding flange thickness matches only Kerdi-Fix adhesive or specified thin-set mortars. Generic flashing tapes will not bond chemically to Schluter’s fleece surface. We stock OEM Schluter membrane rolls, corner pieces, and pipe collars; for the window or door unit itself, we source matching specifications from Andersen, Marvin, or Jeld-Wen where Schluter does not manufacture the sash directly. Measure twice, build it once, write it down - that’s how we avoid a mismatch on an integrated system.

Signs Your Schluter Windows & Doors Is Failing

• Water staining on interior drywall below the sill. This usually means the Kerdi membrane at the sill pan has delaminated or the corner dam (a preformed piece that bridges the sill-to-jamb transition) was omitted during original installation. In Irvine’s coastal-influenced climate, salt air accelerates adhesive fatigue at membrane seams.
• Draft around the frame perimeter despite closed sash. The compression seal between window unit and Schluter Kerdi-Board rough opening may have shrunk, or the spray-foam backer was installed without proper low-expansion specification, creating gaps as the framing cycles with temperature.
• Exterior trim or stucco cracking in a radiating pattern from the frame. This indicates structural movement at the rough opening, often because the Schluter system was installed without proper shimming or because the Kerdi-Board substrate flexed where a wood buck should have been used for rigidity.
• Condensation between panes on dual-glazed units. The insulated glass seal has failed; this is a sash issue, not a membrane issue, but in Schluter-integrated systems the sash must be removed without disturbing the waterproofed rough opening, which requires specific technique.
• Difficulty latching or visible sash warp. Vinyl sash profiles in direct south or west exposure in Irvine can experience thermal deformation exceeding ⅛-inch over a 6-foot span, especially on older units predating Schluter’s current reinforcement schedule.

Replacement Cost & What’s Included

For Schluter-integrated window and door replacement in Irvine, our installed pricing follows the ranges above. What drives the spread: unit size (a 3-foot by 5-foot casement runs toward the lower end; a 6-foot sliding door or impact-rated picture window toward the upper), whether the Kerdi membrane rough opening must be rebuilt, and stucco repair scope after removal.

Every quote we write itemizes parts, labor, and permit fees separately. Under Clause 1 of the Haven Standard, that written price is fixed before work starts; no change proceeds without a signed change order. Our work carries the 365-Day Done Right Promise, and every visit includes a documented photo record of the rough opening condition, membrane installation, and final seal testing. We pull permits where Irvine requires them and schedule inspections as part of the scope.

DIY or Call Us?

An owner can safely inspect: check the Schluter label for model and date code, photograph any staining pattern for our review, and verify whether the sill pan corner dams are visible from the exterior (they should form a continuous upturned leg at each jamb). What you should not attempt: removing a Schluter-integrated unit without proper shoring of the rough opening, or applying new membrane over compromised substrate. The waterproofing warranty is void if the fleece surface is contaminated with dust or previous adhesive residue, and in Irvine’s variable humidity, improper curing invites mold within the wall cavity.

We’re an independent service provider, not affiliated with Schluter Systems. If you’re seeing any of the symptoms above, call (657) 227-2502 to schedule your free estimate. We’ll assess the membrane condition, identify the exact unit specification, and give you a written price before any work starts.
