  ⭐⭐⭐⭐⭐

An absolutely exceptional experience from start to finish. The quality of both the products and the service has been unrivalled, and every single member of the team has been a genuine pleasure to deal with.

Alan in Sales was fantastic — knowledgeable, helpful and professional throughout. Kierra in Billing was equally brilliant and made everything straightforward and easy.

A special mention has to go to the fitting team, Ewan and Tyler. Their workmanship was of an exceptional standard, and their professionalism was second to none. They were a joy to have around — polite, respectful, tidy and clearly took great pride in what they do.

The finished windows look fantastic, and the quality is outstanding. From the initial sales process right through to the fitting and aftercare, the whole experience has been first class.

We honestly couldn’t recommend this company highly enough. Exceptional people, exceptional products and exceptional service — absolutely delighted with the result!

  We had replacement windows throughout and a new front door from St Helens Windows, installed on June 8, 2026. Everything went brilliantly from the very start - from when the rep Alan came to measure and price (who was not at all pushy, just very nice and helpful), from phone calls and communications with the company, to the actual installation. All excellent. The team arrived on time - Ewan and Tyler - and got stuck in promptly with enthusiasm. The whole process took only two days. At the same time the company installed a new front door for my son at another local address, and he was equally happy with the entire process. I would not hesitate to use the company again in the future for any further work required and would wholeheartedly recommend them. Thank you once again to all at St Helens Windows.

  Very good information on the order taking visit and on the measuring up visit. Quick service from order being placed to the instalation date.
The removal of old fittings and fitting of replacements was completed in the set time and to a very high stanadard by the fitter and he made sure that he kept everything neat and tidy.
The total service from first visit to completion of the job was first rate and we could not of been more satisfied.
WELL DONE  to all concerned.

Upgrade To Energy-Efficient Double-Glazed Windows

Modern double-glazed windows can help improve your home’s energy efficiency throughout the year.
Two panes of glass separated by a sealed cavity help reduce heat transfer through the window.
Improved insulation can help keep your home warmer during colder months and more comfortable throughout the year.
Energy-efficient replacement windows may also help reduce heating costs over time.
A-rated window options are available depending on the chosen frame and glazing specification.
Different glazing options can help reduce the amount of outside noise entering your home.
This can be particularly useful for properties near busy roads or in built-up areas.
The level of noise reduction will depend on the glass and overall window specification selected.

What Are the Advantages of Double-Glazed Windows?

Double glazing uses two panes of glass separated by a sealed cavity. Depending on the glazing specification, the space between the panes may contain air or an inert gas such as argon to help improve thermal performance.

Benefits of modern double glazing can include:

– Reduced heat loss through windows
– Improved thermal comfort throughout the year
– Reduced outside noise
– Improved window security when combined with modern locking systems
– Reduced likelihood of condensation forming on the inside surface of the glass
– Low-maintenance frame options
– A wide choice of styles, colours and finishes

The exact performance of a double-glazed window depends on the frame, glass, spacer system and overall specification chosen.

Other Benefits Of Double Glazing

Energy efficiency
Noise reduction
Security
Condensation reduction

Double glazing improves insulation because two panes of glass create a barrier that reduces heat transfer and noise. We create our double-glazed windows in-house at our St Helens plant, utilising materials from leading profile suppliers VEKA and ALUK. Our window and door ranges include modern locking options designed to improve security.

Double Glazing FAQs

Double glazing consists of two panes of glass separated by an air or gas-filled gap. The layer functions as insulation, minimising heat loss, boosting energy efficiency, and offering superior noise reduction compared to single-glass windows.

Double glazing improves insulation and can help your home achieve an A+ energy rating. Lowering heat loss in winter and keeping your home cooler in summer may help lower your energy costs over time.

We manufacture high-quality uPVC windows in-house at our St Helens factory, using trusted VEKA profiles. With over 30 years of experience, excellent customer service, and local expertise, we are one of the leading double glazing companies in St Helens.
