UPVC Windows Uxbridge

At Sovereign windows we pride ourselves in providing high-quality installation of UPVC windows in and around the Uxbridge area.

In order to guarantee that they will take the utmost care while installing your windows, we also pay our installers for each day rather than for each product that they install. This means that none of our installers has any incentive to rush any job and will give each job the attention to detail that is needed.

With over 40 years experience as a family business we are more than comfortable quoting in the traditional way in a home consultation with our a friendly team member. However, we also want to give our customers the maximum amount of flexibility and make the process of getting new UPVC windows easy. 

That’s why we now offer remote quotation services via video chat. This means we can even consult with you and a partner at another location, like their workplace. With the latest in quoting technology we can show you a range of styles, frames and partitions and how they will look on your home. 

This makes your free quote for window installation simple to understand, with all the potential costs in black and white, no hidden charges or nasty surprises. 

Benefits of UPVC Windows,

There are a number of advantages to choosing UPVC windows for your home. One of the major ones is that they require such a small amount of ongoing maintenance.

Once fitted, you really have to do very little indeed compared to wooden framed windows, for example, which need to be painted every few years to keep them in top condition. Just a wipe over with a damp cloth is all that is required to keep your UPVC windows looking like they did on day one. This is a very important feature for saving you time and effort while also helping you to keep your home clean.

Another important factor when looking at UPVC rather than wood for your home is that it will make it warmer. Unlike other sorts of materials that have been used in the past, UPVC is thoroughly modern and keeps out water from outside. Even in a howling gale, the frames fit tightly to the glazed panes as well as to the walls of the building to ensure that no draughts are felt.

Once you have experienced the benefit of having UPVC windows in your home, you will wonder how you ever lived without them. By reducing the amount of heat that leaves your home you will therefore be able to reduce the amount that you use your central heating. This will help to reduce the cost of heating in your home as well as reducing your carbon footprint.

Additional Benefits

UPVC windows also offer a great deal of sound isolation. This is ideal for people who live next to busy roads or who want to minimise external noises when they shut their windows.
From a different perspective, this is also a benefit for anyone that tends to make a lot of noise in their home as this will reduce the amount of sound that travels outside as well. For anyone that likes to listen to music regularly, this makes UPVC windows a great choice.

UPVC windows are also designed with your security in mind. By using double glazing rather than single glazing, it is much more difficult for any potential burglar to break through. On top of this, the multi-point locking systems on UPVC windows make it more difficult to force open. Check out our service area location pages for double glazing in Slough and double glazing in Harrow.

Finally, UPVC windows also deny any criminal the opportunity to remove the glass pane from outside in order to enter your home undetected as the glass is internally beaded.

Furthermore, installing new UPVC Windows in your house can also increase the resale value of your home as many potential buyers will be looking for a home that is well insulated, having UPVC windows will also show that your home has had relatively recent renovation work done to the property.

Our Customers Reviews

Don’t take our word for it, see what our clients say

I recently had porch doors fitted by Sovereign Glass. The Price was very competitive. They arrived when they said they would and installed the doors without a hitch. The fitters were very considerate and polite. The doors look very good and have been much admired, the house is certainly warmer. When I Phoned to make the initial appointment I was very satisfied and we created a contract. I had patio and windows fitted the year before . When I hit a hitch with locking the door I phoned and they came within as hour corrected the hinge and explained how to avoid the problem in the future.
