“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 .

In the UK, double glazing can cost between £150 to £600 and above per window. There are many factors to consider which will affect the overall cost of double glazing such as the frame and type of glass.

PVC is the most commonly used frame material for double glazing because of its efficiency and lower price. Aluminium and wooden frames are more costly. When it comes to style of double glazed windows, the most popular are casement and sash.

There is a choice of approximately 18 different window types you can have installed or replaced in your home. These have the options of different styles, window frame options, energy efficiency ratings and glass.

The 5 most common types of window frame materials for replacement windows include aluminum windows, composite windows, vinyl windows, fiberglass windows, and traditional wooden window frames.

On average, you can expect to pay somewhere between £500 and £2500 for a standard front door. For a custom-made door, the cost will be between £2000 and £4500.

It will take around five or six hours to replace a front door. An interior door can be done much quicker as it does not require the same caulking, flashing, and other weatherproofing steps.

On average, door repair services usually cost £60 to £100 but this can vary depending on a number of factors.

On average, the cost of repairing a standard sized broken window is between £100 to £150. To repair a large blown window you’re looking at a price closer to £350 all the way up to £850.
