Factors Affecting the Cost of Replacing Sash Windows 

There are many variables that come into play when budgeting for new double glazed sash windows. The following factors should be considered. 

Profile

The profile of your replacement sash windows is one of the largest factors affecting the cost. Whether you select uPVC windows, aluminium windows or timber, each material varies in cost. uPVC is the cheapest and timber is the most expensive option. 

It’s worth noting that some people who like the look of traditional timber sash windows will opt for wood grain uPVC sash windows to save on costs, convenience, easy maintenance, and never needs repainting.

Colour

Colour can have a large impact on the cost of sash windows. The cheapest uPVC sash window is white, and you can expect to pay 30% to 40% more for any other colour. The finish of the colour, such as a woodgrain effect, can also influence the price.

Window Measurements & Number of Windows

Of course, the number of windows and the size of your replacement windows all differ from property to property. You may wish to replace a window one at a time, or budget for the entire house to be completed at once.

Window Style

There are a huge variety of window styles available when it comes to replacing your windows, and these all differ in price. 

Glazing Type

The type of glass you select, whether that be single, double, triple, or frosted, affects the cost. Many people opt for double glazing which offers many benefits when compared to single glazing. 

Location

Your location can have a significant impact on the cost of your windows due to the higher living costs in certain areas such as London. 

Installation

The cost of installation is one of the biggest factors to consider, and the number of windows. The more time-consuming the job influences the amount and cost of labour needed.

Another huge factor to consider depends on whether you’re having new windows fitted or replacing old windows. The cost of removing sash windows can take time, along with the number of windows needed to be fitted. 

Many double glazing installers and window companies in Leicester will offer competitive prices but the cheapest option doesn’t always mean the best quality windows or installation. Consider reviews and accreditations before making your final decision.

Professional, skilled, great communication from the on-site team - honestly, the best workmen I’ve ever had. They left the place tidy and neat. Thanks guys! They did a great job on a dreary, winter’s day with a smile. I love the new porch, which was a decent price. Honestly though, the sales guy Tom and the crew of Cal, Jake and Aaron were great. After having had a bad experience before with a different company, I’ll be using Phair Windows to replace my windows in the near future as well.
