Double Glazing Repairs & Window Replacement
While double glazing has advanced to be highly durable and hardwearing, there may come a point where one of your windows breaks. Our installers offer repair and replacement services to have your windows looking as good as new in no time.
Repairs can usually be carried out on broken locks, internal beading, cracked and dented frames and misting windows with trapped condensation.
Sometimes however, a repair job is not appropriate and your installer will recommend you get the unit replaced. We only work with honest and trustworthy companies to ensure that you will never be told that you need a replacement if a repair is a viable option.
How Much Does it Cost to Install Double Pane Windows?
When you use our pricing guide tables, our cost calculators or our online quotes, the price you receive will reflect the cost of the double glazing itself, as well as installation, surveying, a warranty, VAT and compliance certification. This helps to ensure that you aren’t surprised by unexpected costs later on in your installation.
For people that would prefer to receive the products and install them themselves, we work with companies that offer supply only double glazing.
Bear in mind, however, that installing your own windows and doors is a time-consuming and difficult task for even the most experienced of DIY enthusiasts. You also will have to deal with building regulations, which your installer would normally take care of on your behalf.
What is The Cost of New Double Glazing?
The cost of new double glazing will depend on the size, style, decorative options and finishes you choose. A 500mm x 500mm casement window in white can cost as little as £150. However, larger and more ornate windows with wood grain finishes or decorative glass will cost significantly more.
Try our online costing calculators to get prices for windows of your choice.

Should I replace my old sash windows with uPVC?
Sash windows are a key feature for many traditional period homes and are traditionally made using timber. Timber windows, however, are notoriously high maintenance and over time are prone to becoming draughty, as well as cracking or warping. uPVC sash windows are a great way to keep your home’s beautiful traditional aesthetic while enjoying all the benefits of modern double glazing, such as increased thermal performance and security.
How much is a conservatory?
If you are in need of more space in your home and are considering getting an extension, a conservatory could be a much more cost effective option that won’t require you to apply for planning permission. They also add a significant amount to the value of a property. A lean-to conservatory starts at £6000, with other styles of conservatory normally being more expensive. Use our pricing table to get the costs for your ideal conservatory.
How much do composite doors cost?
Composite doors are an ideal way to replicate the classic look and feel of timber, but with increased soundproofing, thermal performance, durability, security and weatherproofing. Composite doors feature an insulating core which works to keep warm air trapped inside your home, meaning that you will rely less heavily on your central heating and save money on your energy bills. They are then covered with a durable outer skin which is extremely weatherproof and scratch resistant as well as incredibly strong. Composite doors are available in a number of colours and with a range of decorative glazing. They can also be fitted with practical items such as catflaps. Prices for composite doors, being that they are such a top of the range product, do start fairly high at £1000. For different glazing styles, this price can increase to £1500. However, if this is within your home improvement budget, a composite door is a welcome addition to any home.
