Why Upgrade Your Windows and Doors
Respecting the Character of Older Homes

Draft-Proofing and Window Repplacement
Older windows and doors are one of the biggest sources of heat loss in New Zealand homes. Draughts, condensation, and cold glass surfaces can make rooms uncomfortable and harder to heat, especially during Dunedin winters.
Installing new windows and doors or retrofitting double glazing can deliver immediate benefits, including improved warmth, reduced condensation, less outside noise, and better overall comfort.
Many homeowners tell us it is one of the most noticeable improvements they make to their home.

Repair or Replace. Practical Advice You Can Trust
Dunedin is well known for its character homes, including villas, bungalows, and older timber houses. While full of charm, many still have original windows and doors that are draughty and inefficient by modern standards.
We specialise in solutions that respect the character of older homes while improving their performance. This may include repairing or upgrading existing timber joinery, retrofitting double glazing, or installing new timber windows and doors that suit the style of the property.
Our approach focuses on practical improvements without unnecessary disruption or loss of character.
