Expert Installation With Great Value

Double Glazing Stevenage

At Fenster, we install high-quality double glazing in your home in Stevenage. When you choose double glazing, it comes with lots of advantages for you to consider. You will get lots of security and thermal efficiency, which saves you money on your energy bills because you don’t need to use the central heating or turn on the thermostat. It will increase your comfort and safety, too. You have a choice of uPVC and aluminium windows and doors.

 

When you choose Fenster for double glazing, you can benefit from many different customisation options, including a range of colours and finishes that can help you personalise your Stevenage home. Go for a vibrant colour that will help your home stand out, or you can even go for something more muted to blend in with your property. The choice is entirely yours.

 

We install products including uPVC casement windows, flush casement windows, sliding sash windows, French casement windows, tilt & turn windows, bow and bay windows, aluminium windows, heritage windows, aluminium doors, uPVC doors, composite doors, bifold doors, French doors, patio doors, and even roof lanterns.

 

Double glazed windows can also ensure your home has less condensation because they will reduce the amount of moisture on your window or door. This is because the frames are airtight and watertight, so you will not have to worry about water or cold air seeping in. As a result, your home will be much warmer in the long run.

 

The double glazing that we install is very high quality and lets in floods of natural light into your home. This will save you money on your electricity bills because you won’t have to turn on the lights. Furthermore, the thick panes create a robust thermal barrier, which will keep natural heat in your home in the winter, reducing rising energy costs. It also works well in the summer because it can help reduce the glare of the sun while letting in more fresh air. This will save you money on your air conditioning. For an even more advanced shading solution, we also offer integral blinds in between your double glazing.

 

With more double glazing units in your home, you can feel safer from burglars because the windows have multi-point locking systems and robust hinges included. This will keep you and your loved ones safer for longer. The units will also help increase your privacy levels, which is ideal if you live in a noisy area such as an airport or a busy road. These sounds will be reduced to a hush.

Thermally Efficient uPVC Windows and Doors

At Fenster, we offer double glazing for both your windows and doors. One of the main benefits is that they are thermally efficient, while you can feel very confident that they will be secure in the long run. Less energy will be used to heat or cool a room, which means you don’t have to use your central heating or the thermostat.

When you add more layers of glazing, you will save money on rising energy costs, and you can spend money on the things that matter. This way, you will have more control over your temperature, saving you money all year round. The doors contain aluminium extrusions that are separated by polyamide thermal breaks.

They are reinforced with glass fibre and a PU insulated chamber, which help you stay warmer for longer periods.

Additionally, lowering your energy usage will reduce your carbon footprint. You will save the environment and contribute to a greener planet in the process. There is something out there for everyone, so we are confident we will find something for you.

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

Nicky Kent

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’d give 6 stars if I could! I’ve just had a new door fitted by these guys, absolutely amazing service and very fair price! I cannot fault a single thing! Thank you fenster!!

Laura B

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.
