FAQ

Frequently Asked Questions

Yes. Milton's Building Services portal handles same-day intake for like-for-like replacements; structural changes need P.Eng-sealed lintel details. Our in-house engineer turns those drawings around within 48 hours so the file isn't waiting on us.
Yes. Old Milton's Main Street has 1860s stone and brick cottages with low-headroom openings — we measure each opening individually and build shorter sashes rather than dropping a header to fit a stock unit, so the daylight opening isn't lost.
Often — builder-grade dual-pane installed 15–20 years ago commonly shows seal failure now. Triple-pane upgrades pay back in comfort and bills.
Yes — we upgrade frame reinforcement and sealing on homes with direct wind exposure.
Most Milton jobs go from measurement to install in 7–9 weeks. Beaty and Willmott new-build retrofits usually wrap in a single day on site; Old Milton heritage projects with brick repair and trim work run 2–3 days.
