Sash & Case Windows

Replacing your Windows

How do I measure a sash & case window?

We ask you to provide rough measurements of your windows during the estimate process. The best way to do this is to measure the width, from pulley stile to pulley stile and to wall, and the height, from sill to lintel. Diagram.

Do you install uPVC windows?

Yes, as well as traditional timber windows, we offer uPVC alternative. We also supply and fit various types of external doors.

What is the difference between wood and uPVC windows?

There are pros and cons to both options. Both will give excellent energy efficiency and will look great. Both are available with double glazed units.

Timber frames are precision-made for smooth movement. These will require regular maintenance, but proper upkeep will ensure they last a lifetime, adding value to your home.

uPVC is low maintenance and cost effective. However, plastic can discolour and can become brittle over time, and if a fault occurs, repairs are difficult to carry out and windows may need replaced if over 10 years old.

Can you replace the glass only?

No, we recommend seeking advice from a glazier.

My windows aren’t sash and case, do you install other types?

We are primarily sash and case, but we also offer other types of windows such as casement uPVC and Velux. Please get in touch to discuss your window project.

How do I care for my new sash & case windows?

Please refer to our handy guide to maintaining your sash & Case windows.

What type of glazing do you offer?

We offer 3 types: single-glazing; Double-glazing; and Heritage Double-glazing.

Renovating your Windows

Should I renovate or replace my windows?

A lot will depend on condition and what repairs are required. In some instances it may be more cost effective to replace which will give you a better performing, energy efficient window.

Benefits of replacing will instantly add value to your property, reduce heating bills and save energy, reduce outside noise while improving the overall look of your property.

It’s a tough choice if cost is an issue.

Here is a handy guide to assessing your windows.

What type of services do you offer for a window refurbishment?

We offer a solution to most common problems; re-roping sash cords; draughtproofing; sand mastic replacement; replace parting beads and brushes, baton rods, ironmongery and Simplex fittings.

Do you fit double glazed units into a single glazed sash?

No. We do not provide this service as the original sashes were made for 4mm glass. Fitting double-glazed unit into an existing single-glazed sash would compromise the strength and integrity of the sashes. We would propose a complete replacement as it is more cost effective and gives a better performing window, this is due to the draughtproofing system being fitted during the manufacturing process, ensuring precision and overall quality.

What is secondary glazing?

Secondary glazing involves adding another slimline glazed panel to the inside of your existing windows. It is an extremely cost-effective method of insulating and soundproofing your windows whilst reducing waste and resource consumption. This is more popular in A-listed buildings due to strict regulations in place.

Listed Buildings & Conservation Areas

Can I install new windows and doors in my listed property?

If you live in a listed home, windows and doors cannot be changed without listed building consent. We have a guide to help you determine if your windows require listed building consent.

How do I know if I live in a conservation area or if my property is listed?

If you are unsure of your home’s status search the Historic Environment Scotland portal

Are your windows fully compliant with current building regulations?

Yes, our windows are fully manufactured to replicate traditional features, on a like for like basis, in line with listed building and conservation regulations.

Is your timber sustainably sourced?

We carefully select reputable timber suppliers who take their environmental responsibility seriously, ensuring that every material, from chipboard and MDF to quality hardwood is 100% sourced from FSC Certified manufacturers and processors.
