Not only do windows bring light and air into your home, and keep out the cold and noise of the streets outside, they also make a big difference to the character of your house. A change of windows makes a property better heat-insulated (saving on energy bills) and sound-proofed, and can update it in an instant. Nothing says unkempt like dingy windows with rotting sills.
If your windows are reflecting badly on your house, then it’s time to make a change. But buying and installing windows – particularly double-glazing – has always been seen as an expensive job which must be left to the professionals. Maybe, like many home-owners, you’re saving up to replace the guest beds in the spare room, the units in the kitchen or the shower in the en-suite. New windows, however, are not necessarily out of budget, if you do the job yourself.
Before you start altering any windows, ensure the new ones will comply with any regulations regarding fire escapes and safety issues. In addition to this, the success or failure of your installation will depend on your measurements. Measuring from the outside, find the narrowest point and then deduct 5mm from the width and height. Make sure you include the sill thickness (normally 30mm), and include details about this when you order the windows. Choose your supplier carefully. Just as if you were buying a new king size bed, you’d go to a reputable firm like Bensons For Beds, make sure you go to a supplier whose products are guaranteed and have reasonable delivery charges.
Fit the frame from the outside. Handling the frame should not be too difficult as most frames when not glazed, are fairly light. However, it is always helpful to have another pair of hands, particularly if the window-frame is large. Screw the frame into the brick or block-work, using 6” frame-fixers. Next, fit the glass into the frame. Packers are used to lift the glass so water can freely drain out of the frame. A common cause of unit failure is water freezing around the bottom seal. Fill any large gaps between the frame and the wall with expandable foam. Don’t do the gap-filling before fitting the glass, as it can distort the frame and then the glass would not fit. Then, using a quality silicon and plenty of kitchen towel to clean up as you go along, finish the edges around the window frame, and you’re done.
