Sash Window Opening

Fitting Sash Windows

Sash windows are becoming more and more popular every year.

They can give your home the right balance between a traditional and modern style.

The problem is that sash windows have a bit of a reputation for being difficult to fit and maintain.

They often need replacing but this doesn’t have to be the case.

To help our customers, we’ve written this brief guide on fitting replacement sash windows to help you out.

Measuring the frame

First of all, you need to measure the frame that is already there in the wall.

Make sure you measure straight across from the jamb to the opposite jamb for the width.

Then measure from the sill to the head jamb for the height.

Removing old sashes

Now you need to pry off any window stops on the sides of the sashes.

Locate the lower sash, pull it out, and disconnect the chain.

Next is the parting bead, a trim in a recessed sort of groove – remove it in pieces and discard them.

The upper sash needs to be removed as well, and also disconnect the chain like before.

The pulleys need to be removed next but you can discard them straight away.

Inspecting the frame

Take a look at the existing frame – is it in good condition?

Replace or repair the rotted sections, and make sure the head and sill jambs are both level.

Lastly, check that the side jambs are both plumb.

Jamb liners

Install the liner clips.

You need to check the manufacture’s specifications, but usually one is needed about four inches from the head jamb and another at four inches up from the sill.

Place several more in between this – the number is based on the height of the window jamb.

The clips can be installed by putting them up against the outer window trim, then taking them back about an eighth of an inch.

Drill a hole for starters, then put your nail in place using one-inch roofing nails that are galvanised.

Make sure you don’t get the nails in too tight – if you do, you might not be able to move them around if necessary.

Also make sure to install the brackets evenly to ensure the tabs fit in the jamb liners. On each side, snap the jamb liner into place.

Installing the sashes

The top sash is the best place to start – tilt it into the opening and engage the lower pin in the metal cam in the liner.

The other side needs to be lowered until the pin also hits the metal cam.

Lift the sash, push the jamb liner, and ease the sash to its position.

Do this for the lower sash as well now.

Sash Windows Alternatives

Alternative Options to Sash Windows

Most people want traditionally styled sash windows for their homes, but it isn’t always possible due to prices and design issues.

There are many other types of windows you can have though, and we’ve written this short guide to help you decide.

Casement windows

The first window on our list, the casement window, is the oldest style of window.

Casement windows are the most versatile and suit most types of properties.

You can choose single or double panels (or more panels if you have the space), and they are highly energy efficient.

Tilt and Turn windows

Popular for their uPVC double glazing, tilt and turn windows are hung either on their sides so they can swing fully open, or they are hung at the bottom to tilt inwards.

It is this ability to open in different ways that makes them even more popular.

One benefit of opening them completely is that you can clean the glass from inside the property.

You’ll find tilt and turn windows on more modern properties.

Sliding windows

A sliding window means allowing the frame to slide horizontally like a patio door.

They are perfect for kitchens, where you can easily slide them open and walk out to a patio with food or drinks in your hands.

They are often large and function as doors, but they can also be small like serving hatches.

Sliding windows suit modern properties.

They are usually very energy efficient and suitable for keeping out noise.

Bay windows

Bay windows are usually seen in classic Edwardian and Victorian houses, and for this reason they are considered very stylish.

The bay window serves as a focal point for the house, projecting from the wall with extended brickwork.

They are not just for style, however, as the extended are a gives more space and light to the room, lets in more air, and allows for more of a panoramic view.

The only downside to new bay windows is that they need planning permission.

Bow windows

Similar to the bay window, a bow window also projects from the wall but without adding any extra bricks.

Bow windows sort of float without anything underneath.

Just like bay windows, bow windows let in more light and more air and they offer panoramic views.

However, they are also handy for creating extra shelving space, and often they can also make rooms feel that little bit bigger.

People often choose bow windows if they don’t want to go through the hassle of getting planning permission for bay windows.
