Expert Installation With Great Value

Double Glazing Letchworth

Fenster installs high-quality double glazing for Letchworth homeowners. There are many benefits to installing double glazing that you should think about. Your home will benefit from increased security and thermal efficiency, which will save you money on your energy costs because you will not need to utilise central heating or turn on the thermostat as often. It will also improve your comfort and safety.

When you pick Fenster for your double glazing solution, you will benefit from a variety of customisation options, including a variety of colours and finishes. We make it easy to tailor your home improvement to your Letchworth residence. Choose a vivid colour that will help your home stand out, or go for something more muted that will blend seamlessly with your property. The decision is entirely up to you.

We install a vast collection of double glazing products, including: uPVC casement windows, heritage windows, flush casement windows, sliding sash windows, aluminium windows, aluminium bifold doors, uPVC doors, composite doors, bifold doors, French doorspatio doors, and more.

Our double glazing products are all high quality, air tight and watertight. You won’t get cold draughts through joins or edges. Our double glazing helps prevent condensation forming in your home by reducing the amount of moisture on your windows and doors. As a result, your house will be significantly warmer in the long run.

We install high-quality double glazing that allows plenty of natural light into your home. You won’t have to rely on artificial overhead lighting, meaning you’ll save money on your electricity bill. Furthermore, the thick panes form a strong thermal barrier that keeps natural heat in your home during the winter, further lowering your rising energy expenses. Its excellent heat retention and minimized thermal transmission will also help in the summer months by lessening sun glare and keeping excessive heat out of the home.

Each of our double glazing products is carefully designed for security too. You will feel protected from intruders because the windows contain multi-point locking systems and sturdy hinges. This will keep you and your loved ones safer for a longer period of time. The units will also help you boost your privacy, which is great if you live in a noisy place like an airport or a busy road. These noises will be reduced to silence by the noise reducing advanced double glazing.

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’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.
