Window Questions, Answered
How long does a typical window replacement take?
Most homes are completed in 1–2 days depending on the number of windows and any prep work. We'll give you a clear timeline at your consultation.
Do you handle both replacement and new construction windows?
Yes. We install retrofit replacements as well as new-construction windows for additions and remodels.
Are your installers in-house?
Yes — installations are performed by our trained Mighty Builders team, not subcontracted to third parties.
Will new windows really help with energy efficiency?
Modern dual-pane, Low-E glass packages can meaningfully reduce heat gain and drafts compared to older single-pane windows.
Do you pull permits?
When a permit is required by your city or HOA, we coordinate the paperwork so the job is done to code.
