Regulations For Removing And Replacing Windows
Replacing windows and doors must be done in line with regulations and to undertake such work we suggest you first look at our project on replacement windows and doors.
In 2002 building regulations changed dramatically to keep energy in buildings as much as possible. From the roof to the floor, insulation requirements changed and this includes the windows. Please click on and read our project relating to these regulations to find out more.
Measuring up for your new windows or doors an be a bit tricky and needs to be done correctly. More information on how to do this can be found in the Replacing Windows and Doors project mentioned above.
Remove All The Moving Parts From Your Windows
The first step to removing window and door frames is to remove the moving parts such as the door itself or the windows opening sashes. Usually this can be done by unscrewing the hinges but in a few, awkward cases, a wrecking bar and some elbow grease is required.
Once removed, stack all frame sections out of the way, especially those containing glass.
Remove The Central Uprights From The Windows
Saw through the central uprights (mullions) of the frame to remove and fixed sashes or glass panels. Be very careful here as the glass can easily break at this point. When you have made your saw cuts, bang the frame sections away from the glass using a hammer and chisel. All saw cuts should be made at an angle so the timber sections do not bind on each other when pulling apart.
Removing The Main Frame And Side Jambs
With all central frame sections gone its time to cut through the main frame. The sides (jambs) are the first to go and a saw cut is made through them until the saw reaches (but doesn’t touch) the plaster inside and the masonry outside. Again you can see that the saw cut is made at an angle
Once the saw cut is started a chisel or wrecking bar is banged in behind the jamb which is then levered inward. As you lever in the saw cut will open and more of the frame will be exposed. This can be sawn and continued until you have sawn all the way through the jamb. The jamb can then be pulled inwards and wiggled around until it breaks free.
Removing The Cill And Head Timber
Next the cill is cut. Again an angled cut is used. The wrecking bar is inserted under the cill from the outside and levered up ward so all of the cill can be cut.
Finally, using exactly the same process, the head timber is removed. This, if it is an upstairs window, can sometimes present difficulties. Very often, above the window on the outside of the building, there is a soffit board which fills the gap between the inside of the facia board and the wall. With some construction techniques the windows are installed and this soffit board is actually fixed to the top of the window frame. Simply ripping the head down can damage the soffit board so go carefully. If the soffit board is fixed down onto the top of the frame, you will need to slide a hacksaw blade between the soffit board and top of frame to cut through the nails or screws.
There is a huge variety of windows and doors available these days and we would suggest visiting the GRP Designs website to find further information on all types of windows, doors, composite doors and folding doors. Their composite doors are especially worth a look, combining the stunning appearance of natural wood with excellent thermal and security properties.
