1. Measure the hole and take off 2mm from each side.


2. remove molding around window this will allow you to see the window frame usually a piece of 1 by measure from the inside of the 1 by sideways and top to bottom the store you order through will subtract from the measurements you have to give you the right size good luck


3. Once the old window has been removed,measure the opening from the out side making allowances that you want a tight fit not too tight about 2 to 3 mm.


4. Get no obligation quotes from several established suppliers.Ask to see sites where their products have been fitted and select from these options.

   It's inadvisable for the average D.I.Y person to measure and/or fit replacement windows,the size of the window opening may vary.Unless the existing window is a standard size a replacement would have to be specially made,if the measurements proved incorrect the product would be non-returnable.



5. It is tempting to go the DIY route particularly in today's economy, but unless you have experience then it will likely end up being less costly in the long run to have a professional install your windows.

   There is a complimentary e-book on replacement windows that contains a ton of useful information on the subject.

6. You need to measure the hole in the brickwork not the window itself and make sure you take into account the height of the windowsill. Measure the height and width in at least three places then take the smallest measurement.

   When you buy the window take off 5mm from the width and 10mm from the height, (and 30mm for the height of the sill). or give the hole measurements to the sale guy and make sure he adjusts the measurements

   If you get them from someone from Kent plastics they will provide everything you need including spacers for the glass panes. Budget for about £250 per window and you should have change.

   However consider buying self tapping bolts instead of the roulplug type with the expanding sleeve as you just have to slot the window in and then drill through the frame and screw in the fastener. Put two screws in each side and two in the base through the sill. dont bother with the top.

   When you fit the window take the protective film off the inside prior to fitting but leave it on the outside. Fit the window and then apply masking tape around the brickwork. If the window is large brace the middle of the frame to prevent the frame sagging and then fill the gap all round the window with expanding foam. Leave to dry for 90 mins then remove the bracing and stick in the packares and glaze the window.

   Leave it 24 hours and then trim off the exces foam & remove the protective film from the outside of the window seal with silicone sealant and apply finishing quadrant around the edge of the window sticking it in place with sealant.

   Do not try to clean up the foam while it is wet or it will go everwhere and will be a nightmare to get off. Dry it will pick off easilly!.

   Lastly, get your windows FENSA certified by the council. Read the regulations!!! or you may end up having to change your windows again.

   Bank on doing a window a day, i could do two / three by the end.
