Transforming a Victorian Home with Double Glazing and a Composite Door

Before & After - Transforming a Victorian Home with New Windows & Doors

Posted by | January 9, 2026

Victorian homes are among the most beautiful and characterful properties in the UK, but they can also be some of the hardest to maintain. Original sash windows, draughty timber frames and worn-out doors often mean higher energy bills and a less comfortable living space.

We take a look at how one Victorian home in Scotland was transformed with new windows and doors showcasing the challenges, the process and the stunning results.

The Challenge: Preserving Character While Improving Comfort

Our clients owned a Victorian sandstone home in Edinburgh. Like many period properties, it had:

  • Original timber sash windows that were draughty and prone to condensation.

  • A front door that looked elegant but had gaps that let in cold air.

  • Insulation issues, making heating costs higher than average.

  • The added difficulty of being in a conservation area, meaning upgrades had to be sympathetic to the building’s historic character.

The goal was clear: replace the old windows and doors with modern, energy-efficient alternatives that would still look authentic.

The Process: Careful Planning & Skilled Installation

  1. Survey & Permissions
    We carried out a detailed survey and supported the homeowners in obtaining permission for replacements in a conservation area.

  2. Choosing the Right Windows
    To maintain the traditional appearance, we recommended uPVC sash windows with a woodgrain foil finish. These provided the authentic look of timber but with far better insulation and zero ongoing painting or sealing.

  3. Selecting a New Door
    A composite front door was chosen in a deep heritage green, complete with traditional brass hardware, to complement the Victorian style while offering modern security.

  4. Installation
    Our installation team carefully removed the old frames, preserving the surrounding stonework. New units were fitted with precision, ensuring airtight seals to prevent draughts.

The Results: A Victorian Home Reimagined

The transformation was striking:

  • Before: Cold rooms, rattling windows, condensation and high energy bills.

  • After: Beautiful sash-style windows that retained period charm, a draught-free composite door and dramatically improved warmth and comfort.

The homeowners reported:

  • A noticeable drop in heating bills within the first winter.

  • Quieter interiors, thanks to modern glazing reducing outside noise.

  • The reassurance of added security from modern locks.

  • Compliments from neighbours who couldn’t tell the windows weren’t original timber!

This before and after new doors and windows project is a great example of how traditional style and modern performance can work hand-in-hand.

FAQs

Can you replace windows in listed Scottish buildings?
Yes, but you’ll usually need planning permission. uPVC sash windows and heritage-style composites are often approved in conservation areas as timber alternatives.

Will new windows really reduce my heating bills?
Absolutely. A-rated windows and doors can cut heat loss by up to 20%, making a big difference in older homes.

Do modern sash windows still slide like originals?
Yes. Today’s uPVC sash designs replicate the look and function of traditional timber but without the draughts and maintenance.

Can composite doors be styled to match Victorian homes?
Yes. Composite doors are available in heritage colours like green, red and navy, with classic hardware options to suit period properties.
