Everything You Need in One Place

Hertford Glass offers a complete range of double glazing and related services.

Perhaps you need to replace your doors and windows or want to extend your home by adding an orangery or conservatory.  Alternatively, you may live in a listed building or property where double glazing isn’t an option – in which case you’ll be looking into the benefits of secondary glazing.

We cover a wide geographical area and our products have been carefully sourced from leading manufacturers to ensure quality. The Hertford Glass team will help you with all aspects of the design, so that your product is tailored to suit your specifications and adds market-appeal.

Customer Comments

May I again compliment your workmen, Rob and Ian, and previously Luke, for their workmanship, tidiness and efficiency in the way the job was done. That now completes our total replacement of all windows and we are very pleased with the end result in both terms of quality and looks. If any of our neighbours enquire, we will be happy to recommend Hertford Glass to them and likewise, if any resident here should go direct to you, we will be happy to show them the quality of work and material carried out at 101. It has been a pleasure dealing with everybody at Hertford Glass from the initial enquiry stage right through to completion. Thank you again.

Liam DeRoe - 2019

What a wonderful, professional set of fitters you sent up. Vince (I think) and his mate were excellent, great work and very tidy. I will certainly recommend you to anyone who asks! Thanks again.

Karl Baker - 2015

Your company recently completed the installation of a further three windows in our property. With regard to Mr Terry Hurt, we would like once again to commend his work as exemplary. What a blessing it is to have a workman with such integrity who works so hard and completes his assignments 100%. We are completely satisfied with our replacement windows and commend your product. Thank you. It has been a real pleasure to do business with you.

Edward & Sylvia Browse - 2015

Can you please pass on this message to whoever is in charge at Hertford Glass. I have just had my windows and front door replaced and I would like to say how pleased my wife and I are with the service we have received from Hertford Glass. Ian and Luke worked extremely hard and completed the work to a very high standard. They started promptly yesterday morning, worked quickly and efficiently, and have left everywhere spick and span. They are both a credit to your company and I will have no hesitation in recommending your service to anyone else. Please also pass on our thanks to Ian and Luke, from two very satisfied customers.

We would like to take this opportunity to say how pleased we are with the service we received recently. We found the tradesmen to be efficient and friendly, and liked that they left our home clean and tidy. All three come highly recommended.

Elaine & Ron Mardling - 2013

Just writing to say a very big thank you for your excellent “after care” service. We have just had new hinges on our back door in relation to draughts and there has been no charge and a very friendly and efficient service throughout. As you know I have used your company since living in this area and will obviously continue to do so. It is so nice and comforting that some firms really care. Wishing you continued success in the future, especially in your new premises.

C Tilbury - 2011

A short note to say how satisfied with the installation team who installed our patio window. I don’t know the installers name but he was efficient and a good worker and we think he made an excellent job of the work he did. Please pass on our thanks for a job well done.

Choose aluminium doors if you want to enjoy long-term benefits that will make your purchase an investment. Here are just a few reasons to make aluminium your material of choice:

Lower U-Values

Choosing aluminium doors that will make your home more effective at retaining heat is important. The double glazing we install will include a polyamide thermal break designed to stop cold air entering your home and heat from escaping.

Lower heating costs will most likely follow the installation of your aluminium doors, and the size of your carbon footprint will shrink. Practically and economically, our doors make sense. Contact us for further details and guideline prices.

Improved Views

Inviting more light into your home will make it feel spacious. Aluminium is incredibly strong, so less of it is needed during the manufacturing process. This results in designs that use less frame and more glass.

Panoramic views of your garden will be created once we’ve installed your aluminium windows. At all times of the year, you’ll be able to enjoy a room space the feels ever-connected to the world beyond your glazing.

Better Durability

Your aluminium doors will be built to last. Strong and weatherproof, they won’t fail when exposed to harsh weather conditions like wind and rain. Instead of rotting or warping, your installation will continue to deliver long-term value.

The inbuilt strength of an aluminium door means it has a second advantage. Intruders attempting to gain access to your home will struggle – even when using great force. This means your installation will protect you from most break-ins.

Unique Designs

The appearance of your aluminium doors matters. Your aim is to match performance with stunning sightlines so that your installation is perfectly balanced. When you choose Hertford Glass, you’ll be able to able to build a product that ticks all your boxes.

Choose from our exquisite range of colours and foils; then complete your installation by selecting your preferred hardware, accessories and glazing. Start creating your dream door now by contacting our team today for a free aluminium doors quote.
