No matter the image it's framing, whether you're looking out or looking in, the art of crafting a truly exceptional window installation, the kind that grabs the attention of any passerby, is something we here at GLS Windows pride ourselves on. When it comes to making a mark on your home, delivering a unique sense of modernity can be on the top of the list but it is easy to forget the dramatic effect windows and doors can have.
I wanted a local company who were well known and came highly recommended and they fit the bill. The quote was reasonable and there were no hidden extras. Everything went according to their promise and I was delighted with the finished job. I would be happy to recommend them to any company or individual as I now know they have a good name in this area.
With over 40 years of experience in domestic glazing including; windows, conservatories, doors, roofline repair, and upgrades GLS Windows & Doors is a name that is trusted throughout the Midlands for delivering quality. We don't just provide quality glazing products but deliver quality workmanship and a commitment to customer care that you can rely on.
A conservatory can truly revolutionise the living space in your home. Teaming with natural light and offering a real connection to the outdoors from the safety and comfort of your house, there's little wonder that properties all over the UK are currently building conservatories of all shapes and sizes.
Just like the habitats they protect, the doors that stand at the entrance to our homes should be beautiful, functional and welcoming. A stylised door can dramatically increase the curb appeal of a property, whilst providing an array of security benefits as well, making them one of the most popular choices for home improvement up and down the country.

Terrible communication from the start. I finally got my windows fitted in October last year after taking several months and being messed around. It was stated that I would receive a FENSA certificate and 10 year guarantee. GLS emailed to ask for my details to send the paperwork, but they never registered my windows with FENSA and I still haven't received the certificate. They have not replied to any of my emails, so I have had to resort to reporting them the FENSA and may have to take further action.
AVOID.

GLS helped us out of a dreadful situation when a double glazing firm in Oadby went out of business taking our money with them. They quoted us to finish our conservatory with compassion in their hearts. They were superb, finished the project with the minimal amount of fuss and disruption and built us a fabulous place to sit in to view our garden. We would highly recommend GLS Windows as they are very professional and hardworking boys. They are extremely neat and tidy workers too.
