Mississauga Skylight FAQs

Do I need a permit for a new skylight?

Many replacements don’t require permits. New openings or structural changes may — we’ll advise during your site visit and help with guidance.

Will a skylight make my home too hot?

Modern skylights use Low-E glass and UV coatings to reduce heat gain while providing bright daylight. Venting options add airflow to release heat and humidity.

How long does installation take?

Standard installs take 1–2 days including interior finishing. Larger custom projects can take longer.

What causes skylight leaks?

Most leaks come from failed flashing or seals. Our repairs focus on proper re-flashing, sealing, and ensuring correct drainage paths.
