For those DIY inclined amongst us, fitting your new UPVC windows may seem like a interesting challenge. While it is a mammoth task requiring time and hard graft, it is by no means impossible. It will require preparation, accuracy and pleanty of research to simplify the process sufficiently. If this is your debut installation, it would be good to start on a small scale. After you have finished your first window, you can move onto something larger. Always take time to make sure you are doing a job right, to avoid paying out later. The first thing you will need is the correct set of tools. To fit a window you will need: A drill A chisel A screwdriver A spirit level Door sealant and frame sealant A saw Frame fixings An 8mm drill bit Before you do anything, check if there is a lintel above the window before you start to remove it. Something to bear in mind is that uPVC windows are not load bearing. Get rid of all items of a breakable nature and anything that could be ruined by any dust. The final step before starting is to check the size of the window matches what you have ordered. On to the removal of any existing windows. The first parts of the window you should remove are the opening sections Use a screwdriver or nail bar to gently remove them. Start off in the top corner and work your way down, removing from the inside by safely cracking the glass pane. Remove any grout or plaster from the frame with a sharp knife carefully. Use a saw to cut through the uprights at an angle, so it makes it easier to pull apart. But don't cut all the way through as you may end up damaging the plaster. Using a chisel, lever where the cut is behind the frame, so that you can cut through at the end. Wiggle the frame and pull to cleanly remove it. Repeat the process again to remove the head timber and sill. Clean up the area, removing any dangerous debris and protrusions. Moving on to the fitting of the new window: If you have decided to install a sill,make sure that the up stand lines up with the plaster line. Level the sill with a 5mm clearance from the brickwork, using the plastic packers. Fix the sill in place with fixing bolts, ensuring that it is level, then apply a sealant at the back edge of the up stand. Finish off with superglue to stick the end caps on. Remove all glazing beads, mark where you have taken them out so that you can put them back in the same position . Slowly place the window into position, between the sill and up stand. Any excess silicone needs to be removed as you go along to avoid a big clean up job later. Pick up a spirit level and ensure that the window is fully vertical against the silicone line. While taking care not to over-pack or damage the framework, wedge the window in to position using the plastic packers. Using plastic packers, wedge the window into place making sure that you don't damage the framework. Secure the base with screws. Then you need to drill it into the brick and insert the frame fixers and screws. Put the glass in place after inserting glazing bridges in the recess located in the frame. Place a bead of silicone between the outside masonry and window frame, then between the plaster and the window. Wipe away any excess silicone before removing any protective tape you may have used. Finally, leave the window for a few hours to let the seals set before opening.
