Whenever you replace your windows, you will face a difficult decision about whether scaffolding is required. There are two primary considerations when making this decision.

First, think about the safety of the fitters who need the risks to be reduced as much as possible. Secondly, consider what will help you to achieve the best finish.

Other factors to consider when deciding are whether you will be working above ground floor height and the size of the windows that need to be replaced.

Scaffolding may seem like an extra expense, but it is hard to put a price on safety. Reputable window companies will not compromise on this issue, and neither should you.

When considering which method is best for replacing windows, you must conduct a thorough risk assessment. It would help if you thought about the number of windows being replaced, the size and any difficulties regarding access.

Surprisingly, it is possible to do the whole job from the outside. First, remove the window; then install a new one by fitting the new frame using expanding foam and applying silicone before fitting the glazing.

This method is best suited to small windows where the risk of a fitter falling out of an opening is small. Larger windows pose a considerably more significant threat to the fitter and anybody in the area below.

The choice with external fitting is between using a ladder and using scaffolding. A ladder or ladders may seem like an economical solution, but it is not a perfect method.

Window units are cumbersome and can require more than one person to get them up to the window from the outside. You may need two separate ladders that must be secured.

Climbing a ladder whilst holding a window is not an easy or safe way of working, especially for a larger window. It may well be more appropriate for a small window.

Scaffolding is a safer and more efficient way of installing windows. It produces a broad, stable base for fitters to balance their tools and the window unit.

Scaffolding will allow workers to do a better job since they can focus and concentrate. Fitters should end up with a superior finish.

Many types of property and situations dictate whether scaffolding is required when replacing windows.

Working with glass poses additional risks. It is best to assess all the different aspects of a job before deciding whether to use scaffolding.

There are some standard criteria that you can use to judge the accessibility and safety aspects of replacing windows. For more details about safety, check out the Glazing and Glass Federation Guidelines.

Height – If you are replacing windows above the first floor, your first thought should be that you should use scaffolding unless you are replacing a single small window that could be done from inside.

Windows that are set back – Windows that are set back from under the roofline are awkward to access. Dormer windows are usually difficult to reach safely without scaffolding.

Lintels – If you need to install a steel above a window opening on the second floor, you will need scaffolding to lift this into place safely.

Conservatories or Extensions – Any extension with a sloping roof that cannot be used as a safe place to stand will prevent access by ladder. Scaffolding is the perfect solution to accessing difficult to reach windows above an extension.

Type of Windows – Different frames and window styles will have different requirements. Aluminium framed windows are more lightweight than some and maybe more suited to alternative methods.

Better Quality Finish – Scaffolding allows installers to fit and trim a window accurately and apply the sealant neatly.

Safety – Scaffolding provides more stability and security for installers to work at a height.

Accessibility – Scaffolding can allow installers to reach awkward windows with overhangs or sloped first-floor extensions.

Time – Scaffolding allows installers to work faster, making them more efficient. It may reduce the labour cost considerably.

Whether you are replacing one window or doing your whole property, you can buy readymade windows and fit yourself, get bespoke windows and fit them yourself or use a window company to do the entire job on your behalf.

You may think that fitting windows is a specialist job, but many competent DIYers can do this with a helpful window fitting kit. If you are a builder, you may choose to quote for fitting windows as part of your contract.

The problem with fitting windows yourself is that you probably will not reach the same standards as a professional fitter.

You may well achieve a good looking result. Still, you are less likely to get the 10-year lifespan that an experienced window company guarantees and certainly not the 20 years that many professionally installed windows last.

The operation of the opening parts may also be hindered if the windows are not fitted correctly. Fitting from the inside involves putting the window pieces together in situ.

Commercial Window fitters usually have a FENSA certification which means they can self-certify their work. If you fit your windows, you will need to get the work inspected for building regulation approval, especially if you want to sell your property in the future.

Window companies will give you a quote that includes the method of installation. They may choose to have scaffolding, use ladders or fit from the inside.

If you decide to fit a window yourself, you will need to make the same kind of assessment before going ahead. The additional cost of hiring scaffolding may pay off in the long run.

When getting quotes from a window company, ask them to break down the cost of using scaffolding. It may be less than you think.

If you decide to go ahead and fit your windows yourself, then get in touch with a professional scaffolding company who can give you advice and an estimate of the cost. They will rent you the scaffolding, erect and take it away to make your life easier.
