What are the types of sash window fitting we offer?



A basic fitting means removing the old and installing the new. Often the good condition of the existing frame helps reduce costs here. Traditional Basic-Fit is the cheapest and most popular “fix.” It is usually undertaken when replacing-sashes-only is required, or when irregular sashes are not available. In this case, they are replaced with a new pair containing a window fitter’s standard specification of glass and putty. They can also be used to replace rotten wood in older sashes.

Our Basic-Fit service involves the replacement of your existing glass or glazing bar with high-performance low E glass. This will guarantee an immediate improvement in your windows’ energy-efficiency level. Our Basic-Fit sash window fittings are suitable for window sills that aren’t too old or damaged. A Basic-Fit is ideal if you want to make your windows draft-proof or if you have just moved into your property and want it redecorated before you move on with the rest of the work.

Complete Fit

A ‘complete fit’ is when we get everything done at the same time. The complete fitting involves cutting fit, protection of your property and a lot more. This means we come along and fit the window in one visit. Some window fitting companies will only deal with the sashes and frames. However, we offer a complete fit, so you are covered from the moment you call us to well after your sash windows are installed into your property. We offer a complete fitting service that is available 24/7 and never charge extra for weekends, evenings and bank holidays. It includes rough draught-proofing, fixing of existing sash cords, tidying, painting and letterboxing all new glazing.

Frequently Asked Questions

How long will it take to complete a sash window fitting?

This depends on how many windows you are fitting. If you fit one window, it might take less than a day – depending on the size, complexity and difficulty of the repair or replacement job. However, you can rest assured that all of our fitters have many years of experience and will carry out your job at a pace that is comfortable for you.

Do I need to be at home when the sash window fitting is being done?

No, you don’t need to be at home when the sash window fitting is being done. A professional sash window installer normally takes the measurements and then fits the windows on a later date when it is convenient for you. The price will be exactly the same, whether or not you are at home, as we always include our travelling time in our quotes.

How do you ensure the safety of my home?

Our sash windows are fitted using state of the art equipment. Furthermore, all members of our staff undergo comprehensive training before undertaking any work on site. This way, you can rest assured that your property is safe in our hands at all times.

I don’t know what kind of window to go for, how can you help me?
