How much will new windows or doors cost?

Every home is different, so we don't give one-size-fits-all prices. We arrange a free, no-obligation survey to take accurate measurements and understand exactly what you need, then give you a clear, fixed written quote. That way the figure you get is real, not a rough guess over the phone.

Do I need planning permission for new windows or doors?

For most homes, like-for-like replacements don't need planning permission. Listed buildings and properties in conservation areas often do, and the rules can vary across Dundee and Tayside. We know the local requirements and will guide you through what's needed, including the application where required.

Will new windows make my home warmer and lower my bills?

Yes. Every window we fit is A-rated and double glazed, with low U-values that keep the heat in and the draughts out. Most homeowners notice a warmer, quieter home and savings on their energy bills year on year.

How secure are your windows and doors?

Very. Our sash windows use high-security locking and a built-in anti-jemmy bar to resist forced entry, and our doors are built around multi-point locking. For extra peace of mind we can supply Secured by Design options, a police-backed standard for safer homes.

Will they suit my period or older home?

Absolutely. Our sash windows are made to measure with authentic detailing like deep bottom rails, sash horns and astragal or Georgian bars, plus a wide range of colours and woodgrain foils, so they keep the character of an older property. We can match almost any RAL or Farrow and Ball colour, and we fit modern styles for contemporary homes too.

What guarantee comes with my windows and doors?

Every installation is FENSA registered and covered by a 10-year guarantee, so your windows meet building regulations and stay protected long after we leave. As a local Dundee and Tayside team, we're always nearby if you ever need us.
