Window and door installation can really open up a home and help bring in more light, a new door can improve access and a new window can frame that beautiful view.

Whether you are planning a window or door installation the first step is to check what type of wall you have that you are planning to knock into and at this stage your advised to get professional help.

Your local planning office is where you will have to apply for permits for your window and door installation. There are numerous reasons for regulations regarding window and door installation regarding the amount you can have and where and how you are allowed to intall them.

By making sure that your project for window and door installation comes up to your local building code standards - it will give you a better chance that the work done will actually add value to your home.

However, really the main reason that we do any additional window and door installion in our homes is to improve the quality of home life - this is what makes it a really worthwhile home improvement project.

A structural engineer will be able to advise you as to the feasability of your proposed window and door installation project - if the wall is a "supporting wall" or not.

He will also be able to advise you on the thickness of the walls - this is key to the method and tools you will need to open up the required hole AND... this will enable you to select the right pre-frame.

What type of Window

What type of window do you want to install, remembering that it should be in keeping with the style and era of your home...

All windows should be made up of five essential elements:

  • The FRAME - attaches window to the wall
  • The SASH - the inner frame that holds the glass
  • The GLASS - clear, tinted or reflective - single or double pane
  • The HARDWARE - hinges, handles/nobs and locks
  • Window SECURITY - glass vibrate or break sensors, window opening alarms, additional locks

With these elements in mind, which type of window do you want to install...

  • A Guilotine type of window has two inner sash frames where at least one moves up and down to open - popular in victorian style houses

  • A Sliding window or SLIDER has one, two or multiple sash glass frames that move from side to side

  • A Central Opening CASEMENT is a double window that opens out from the center - two windows are hinged vertically to open like a double door

  • A Single CASEMENT window is hinged at one side and opens out like a door - this is one of the most common of the smaller window types

  • An Oscillating Window turns on a central hinge and can swing out or even to and fro like a pendulum - these are popular in attic conversions

  • A Fixed Pane window - also known as a picture window which doesn't open

  • A Bespoke window - especially made for unconventional window openings - like the ever more popular round porthole window

The next consideration is the type of material you are going to use, if you are renovating old windows or creating a new aperture for an additional window installation you will want to match the existing materials and style.

A lovely victorian home should have traditional wooden sash windows, the only exception that I can think of is if you live near the sea - salt water spray or particles in the air can seriously deteriorate wooden windows in an alarmingly short time - vinyl or even better, wood-vinyl combination replacement windows would perhaps be a wiser choice in this case.

Generally, replacing or installing additional windows in keeping with your home and even with the style of windows in the area you live in is recommended to ensure that this project helps add value to your home and that approval is granted as required for your building or alterations permit.

Also take into consideration that a sympathetic window and door installation is more likely to be seen as a capital improvement that qualifies for equity based home financing which in turn should make this project eligible for tax deductions!

Marking and Making the Opening

This is how we prepared the opening for a window for a normal thickness wall - a simple window installation.

opening for a window

Measure from the floor upwards to find the lowest point of where you want your window to sit, take into consideration additional space for a window shelf if you are going to include one - (you will need to especially if you get a lot of rain).

Mark an outline of the opening you need to make just larger than the size of the window frame you are going to insert.

With your hammer and chisel - ALWAYS start from the bottom of this area and work upwards to the top taking special care as you hammer near the outline mark top and sides.

Clear away any debris and "Offer up" the window to make sure that the opening is sufficient on all sides.

Use packers to keep the window firmly in place while you carefully seal off and close all holes around the frame and leave it to set dry.

Sand the area near the frame to a smooth finish and paint the wall around the area and to the frame to match the rest of the room.

Before you know it... it will seem like the new window was always there!

Differences in window
and Door Installation

If replacing a door - check to make sure that you choose one of the same height to make use of the original frame if it is still valid.

If you are installing an extra door - perhaps to the side of your home, select the height of the door you want to install, if it is an entry door, both it and the frame should be solid, if it is an interior door you should try to match others in your home - not just in size but also in style.

Standard door heights are 2.10 metres, widths are minimum 60 centimetres but are usually around 1 meter - 1.20 meter. Double doors are the same height of 2.10 meters and usually 2.40 meter wide.

A very important consideration when planning installation is the direction you want your door to open - in our out!, surprisingly in some countries a lot of exterior doors open outwards which is bad for the wood as they are subject to rain and sun and often end up being deformed.

An interior door usually opens inwards to create easy access into a room from a hallway.

This door picture shows a rather a heavy looking door for the interior of a home but this door was initially installed as an entry door - opening inwards...

later part of the outside space was developed as an addition to this home - creating another beautiful and useful room.

The door was then flipped on the frame by changing the hinges to the other side so that it opened out into the new room.
