Everything you need to know before buying Windows, Doors or a Conservatory

Window Installers and Double Glazing Installers

So you have selected the best profile for your windows, they have been manufactured to the highest standards using the best locking system, gaskets and most efficient glass.  The final stage is the fitting the windows in to your home.   In my opinion this is were customers are most critical.

The unprofessional removal of old window frames can damaged external render and brickwork, Internal plaster and tiling as well as expensive wall paper and paintwork that could cost thousands to repair.

Subversively bad fitting of windows can leave them drafty andDouble Glazing Map leaking with badly finished mastic lines.

It really breaks down into 3 main categories of Double glazing firms: -

  • National Companies
  • Large Local Companies
  • Small one man bands

 

National Window Companies

The fitting from large national companies like Anglian, Everest and coldseal can be very hit and miss. These double glazing firms are setup to sell as many windows as they can. I have seen some very good fitting and some very BAD fitting.  Remember that when these fitters turn up it is the first time they are seeing the property, they didnít survey the windows and are paid per window or a percentage of the overall job value.  Because of this the quicker they can fit the windows and move on to the next job the better, they are not interested in recommends The only real way to be happy with the fitting from a national company is to have retained enough of the

money until your happy with the finished product that the company is interested in rectifying the problems.

Large Local Window Companies

I have categorized a large local company as one that have numerous fitting teams but only works in local area. They could manufacture there own windows or buy in. These are easier to see the quality as you can ask to see local installations that have been completed.  Also as a local company they will rely on their reputation as ask neighbors and friends for recommendations. The same applies to retaining a large proportion of the money until you are happy.

Small One Man Bands

These could be one or two fitter with a van, should be FENSA or CERTass registered.  In my option this is where the best fitting can come from. As a small company they will rely very heavily on recommendations so a bad job can be very harmful. Also they will probably sell and survey their own windows so you can build a relationship with them, there is more chance that the things you discussed at the sale or survey will be executed during the installation.  The same rules apply ask to see other installations, speak to friends and neighbors and retain as much money as you can until you are happy
