Expert Installation With Great Value

Double Glazing Hitchin


At Fenster, we install premium double glazing in Hitchin homes. There are several benefits to double glazing that you should think about. You’ll benefit from high levels of security and thermal efficiency, which reduces your demand for central heating and thermostat use, and lowers your energy costs.

When you choose Fenster for double glazing, you will benefit from a wide selection of colours and finishes to help you customise your Hitchin home. Choose a vivid colour to make your house stand out, or you can choose a softer hue to let your house blend in with the neighbourhood. The decision is entirely up to you. We install a variety of goods, such as uPVC casement windows, flush casement windows, sliding sash windows, aluminium windows and doors, uPVC doors, composite doors, bifold doors, French doors and patio doors.

The windows are easy to clean, meaning condensation will be reduced in the long run. All you need to do is wipe them down with a damp cloth, and they will look in pristine condition. If you clean them regularly, they will be enjoyable for a very long time.

The double glazing we install is of the highest calibre and lets natural light flow into your home. You won’t need to switch on the lights, reducing your electricity costs. Additionally, the heavy glass creates a strong thermal barrier that will keep the sun’s heat inside your house during the winter, lowering your energy bills. It also performs well in the summer since it can let in more fresh air while assisting in reducing solar glare. You’ll spend less on air conditioning as a result

As more double glazing units are installed, you may feel protected from intruders because the windows have strong hinges and multi-point locking systems. You and your loved ones will remain safer as a result. Additionally, the units will help you feel more private, which is great if you live near a busy road or an airport. All the loud noises will be reduced to a whisper.

Thermally Efficient uPVC Windows and Doors

At Fenster, we offer high-performance double glazing for both windows and doors. The primary advantages of double glazing is that it’s thermally efficient and very secure. You won’t need to rely on central heating or the thermostat as it will use less energy to heat or cool your space.

By increasing the amount of glazing, you can save money on growing energy expenses and invest that money in more important areas. Our doors have aluminium extrusions with polyamide thermal breaks between them, enhancing their thermal efficiency. With our double glazing, you wont lose precious energy through leaky windows and doors. You’ll be able to control your temperature better and save money all year round.

Our double glazing is strengthened with glass fibre and a PU insulated chamber, which will help your home be much warmer. Your carbon impact will also be smaller if you use less electricity. By protecting the environment, you will help make the world greener. At Fenster, we have something for everyone and we’re confident we can help you find exactly what you need.

The SureFlap Cat Flap

Our SureFlap cat flaps are useful if you have a cat who has trouble entering the house. They have a microchip that prevents trespassing animals from accessing your Hitchin home. To make it simpler and more enjoyable for your pet to enter and exit, we may install your cat flap on walls and doors. You can also choose tunnel installations which provide plenty of depth.

We are very pleased with our new front door. Very good service and excellent quality. Would highly recommend Fenster Glazing.

From start to finish, Fenster have been amazing. Great communication, easy to work with, friendly fitters, flawless windows and a very fair price. I’m so happy I chose them over other companies and have already recommended to several of my friends and colleagues.

Dan Alger

Amazing service! Communication was easy from the beginning and both the professional who came to take measures and the one who finally replaced the windows were extremely friendly, quick, and helpful. I can't recommend enough!

Karen Gómez

I expected great service from Fenster Glazing based on the Trustpilot reviews and that is exactly what I received. Very satisfied customer, the whole process from measuring to fitting of my replacement door was made as easy as it could be for me! Well done to all in the Fenster team. You deserve your 5 star review.

Mark Vincent Smith

Excellent from End to End. Fenster originally came out to us and went through ideas, a couple of designs and all the options available to us. We settled and then changed our mind on a couple of things which was accommodated without question. Installation was superb - quick and efficient and the final product looks great!!

This is the second set of windows we’ve had fitted by Fenster. They are brilliant at every stage and I would highly recommend them. The staff are friendly and professional, they got the job done quickly and well, we’re very pleased with both sets of windows they fitted and would definitely use them again.

I contacted Fenster last week to see if they could help me. My French doors were failing to lock meaning we couldn’t leave the house. They sent Ben out the next morning who replaced the mechanism and also adjusted the door, closing up an annoying gap that’s been there for years. I wouldn’t hesitate to recommend Fenster to friends and family, a really helpful and efficient company.

We couldn't be more delighted with the professional service we received from Fenster Glazing. Nick turned up on time for the initial visit/quote which was fair and reasonable. After accepting the quote a survey was was carried out. The installers arrived on time and were polite and friendly. They covered everything up and left everything clean and tidy. After installation Perry called to check we were happy with the service. The quality of the french doors and windows installed were outstanding. We have no problem recommending this company. We would rate Service, installation and aftercare as 5 star.
I live in Milton Keynes, I contacted Fenster Glazing for an uPVC replacement door. From the beginning to the end, they conducted professional communication, from sales to the technicians coming to replace the door everything was perfect. I had a draught issue with my door and it is resolved now. I want to mention that I am also happy with the quality of the material of the door. I am hoping to have the same quality of service in the future if anything comes up—special thanks to Perry for dealing with everything. Ben

Highly recommended. I wanted a very specific style of doors to fit into our 1930s front porch. Fenster designed them, advised on colour & finish and they have produced exactly what I was looking for. The fitters were very polite and made sure everything was to my standards, and no mess left.
