Glazing Replacement

Glazing Replacement in Preston and across the North West.

In most cases you do not need to change your window frames; replacing the glazing is just as effective and can dramatically increase the efficiency of your home whilst reducing heat loss and cost. We install our ‘Maxitherm+ Insulated glass units’ high performance glazing as standard. We want you to have the best for your home. We can replace the glass into existing PVCu, wooden or aluminium frames, as well as upgrading from single to double glazing.


Double glazing insulated against heat and cold and is up to 90% more effective than single glazing windows and doors. Maybe you have old double glazing but do not want the expense or the hassle of replacing your existing frames. We can upgrade your windows more cost effectively whilst improving the efficiency of your home.

Benefits & Features

  • Minimal waste
  • All of your old glass is 100% recycled
  • More energy efficient
  • Quick and easy to install with minimum disruption to your home


With the correct maintenance, your timber windows can last a lifetime. Upgrading glass into your existing timber frames will save you more than 50% of the cost of new timber frames. Our qualified joiners have vast experience and have worked with delicate and narrow frames to carefully rebate or install stepped units.

Nothing quite beats the beauty of original stained glass units A lot of our customers Have had beautiful original stained glass but despite drafts and heat loss have not replaced their windows because of the attractive features.

This is called an encapsulated unit. Please see our blog post of how we master this process.

What Makes A Maxitherm+ Insulated Glass Unit High Performance?

Maxitherm+ insulated glass units can be made as either double or triple glazed units. They include: a warm edge spacer bar, an argon gas filled cavity improving the thermal insulation efficiency and a pane of soft-coated low-emissivity glass designed to prevent heat escaping through the windows to the cold outdoors in Winter – this also keeps it cooler in the summer by reflecting the heat out.

What’s more, we trust in the longevity of our units so much that on top of your 10 year insurance backed guarantee we also offer a LIFETIME GUARANTEE on glass replacements. Yes that’s right, a LIFETIME!


Our glass recycling programme.

We are proud to have recycled thousands of tonnes of glass for over 10 years. We work closely with the URM group who are the UK’s leading company for buying in and recycling glass. Landfill waste sites can be expensive and are not friendly for the environment. Because we are only charged for transportation of our recycling materials, the money we save we give back to our customers which is the reason behind setting up our independent glass recycling program. Staywarm Energy will absorb a proportion of the cost towards upgrading your glazing for recycling your existing.
