About us

Window glass and door panel repairs by glazing experts.

Our early beings: In the 70’s our first “proper” window and door replacement company was set up, “Wishmore Limited” with a view of getting 35% of our sales from recommendations, whilst dealing with the retail public, a very tall order was set.

The original goal of wanting 35% of the sales from recommendations quickly turned to well over 60% as quality and service was always upmost in our minds.

Around 1976 it was found suppliers and manufacturers were lacking in their quality and service and it was hard to achieve the original goal, so a manufacturing company was set up and it was soon found that by manufacturing a first class product, other window and door companies wanted to buy these products, the view was to set up a company called Wishmore Double Glazing Limited to look after the retail installation work and leave Wishmore Limited to concentrate selling to the window industry, over the years that followed turnover grow to over £7.5M.

In 2009 from a base in Suffolk, a new company was formed called “Mistbegone Limited” mainly to replace double glazed sealed units that have mist in between the two layers of glass of the double glazed sealed units.

Operating at the time in Suffolk, Cambridgeshire and North Essex. A couple of years later the base was moved to the Herts and Essex border changing the brand to “Glazing Masters” mainly operating in Hertfordshire, Essex and East and North London.

We have noticed over the years that the complete windows and doors don’t last as long as some companies tell their customers, with this in mind, we investigated the replacement window and doors industrially and found that the main frame (i.e. the structure) unless damaged, do last a very long time, knowing that the moving parts of a window can be repaired or replace i.e. the locks, hinges, handles, gaskets etc, therefore the only other part of the window, is the double glazed sealed units and we know from experience that there is no problem in replacing the misty, blown or faulty units.

A quote by Pilkington Glass “Why change your windows when you can just upgrade the glass” therefore by installing the latest generation of double glazed sealed units, you will have an energy saving of 56% over the old existing units, saving on heating bills plus by not having the complete windows changed you will save £100’s over having the windows and door replaced.
If you are looking for the complete windows and doors to be replaced, sorry we can’t help! But if you want to save £100’s by keeping your existing frames and having the latest generation double-glazed sealed units installed into your existing frames, we are the company you should be talking to!

Remember, we also offer a complete service of replacing of your misty, blown or failed existing double-glazed sealed units, without replacing your existing frames, together with repairing or replacing locks and handles that are no longer working, replacing the hinges that are letting the draughts through the windows and all our work is fully guaranteed.
