FAQs
Can you replace just the glass without changing the entire window frame?
Yes — in most cases, we can replace only the failed IGU while keeping your existing frame intact.
How long does the replacement process take?
Most standard IGU replacements are completed in 1–2 hours per window, depending on size and accessibility.
Do you offer energy-efficient glass options?
Absolutely — we provide Low-E and argon-filled glass options to improve thermal performance.
Is there a warranty on the replacement work?
Yes — all IGU and window replacements come with a workmanship and materials warranty for peace of mind.
