Why Pure “Window Companies” Fall Short — And Where SkillSee Steps In
Competitors like Window King LA, Metropolitan, or American Deluxe focus solely on quick drop-in retrofits. When your vision involves expanding openings, cutting walls, moving electrical wires, or repairing stucco, they walk away. We handle the entire structural envelope under one licensed roof.

Everything You Need to Know About Windows & Sliders in LA
What is the difference between Retrofit and Full-Frame New Construction?
Retrofit windows (Z-Bar / Flush Fin) fit neatly inside your existing structurally sound aluminum or wood frames. No exterior stucco or interior drywall is touched, making it fast (usually 1 day) and budget-friendly. Full-Frame (New Construction) removes the old frame completely down to the structural studs, allowing us to install heavy-duty waterproof flashing, inspect framing, or expand the opening size.
Can SkillSee turn a standard window into a large sliding glass patio door?
Yes! That is our primary competitive advantage as a licensed General B Contractor. Pure window companies cannot touch framing or structural walls. SkillSee handles precision diamond-saw cutting of the exterior stucco, engineered structural header installation, load-bearing king and jack studs, permit approvals with LADBS, plus all exterior stucco patching and interior drywall/paint.
What happens if there are electrical wires, outlets, or light switches in the wall you need to cut?
Because SkillSee holds both a California General B building license and an in-house C-10 Electrical Contractor license, our crews safely disconnect, reroute, and relocate circuits, outlets, and switches without needing to wait weeks for outside electricians. Everything is permitted and up to current NEC and California Title 24 code.
Do your vinyl windows meet California Title 24 energy code requirements?
Yes, 100%. Our dual-pane vinyl windows and multi-panel sliding doors are manufactured with high-performance Low-E3 reflective microscopic coatings and filled with inert Argon gas. They exceed Title 24 U-factor and Solar Heat Gain Coefficient (SHGC) standards, keeping intense Southern California sun heat out in summer and retaining cozy warmth in winter.
Will you patch the exterior stucco and paint after cutting new openings?
Yes. Unlike window subcontractors who leave rough stucco scars and unsealed seams, SkillSee provides a complete turnkey exterior finish. Our master plasterers apply multi-coat stucco (scratch, brown, and texture coats) matched to your home's existing stucco pattern (smooth, Spanish lace, dash, or sand finish), followed by premium exterior facade painting.
How long does a typical window replacement or slider conversion take?
A standard whole-home retrofit window replacement (6–12 windows) is completed in just 1 to 2 business days with zero mess. A custom sliding door structural conversion (including diamond wall cutting, header framing, door install, and 3-coat stucco) typically takes 3 to 5 business days, including proper cure time for stucco and paint.
