What is The Cost of New Double Glazing?

The cost of new double glazing will depend on the materials you choose, your chosen style, size, decorative accents and finishes. For example, uPVC double glazing will be significantly cheaper than aluminium double glazing, and smaller units are cheaper than larger ones.

By using our online quoting system, you will receive prices from double glazing companies operating in St Albans. This means that you get the best local prices for windows and doors. Comparing prices from several installers is the best way to make sure that you are getting the best price possible for your double glazing.

Double Glazing & Window Replacement

Modern double glazing is specifically fabricated to be hardwearing and durable with little necessary maintenance. However, sometimes accidents happen and you may find yourself in need of a repaired or replaced window. The installers we work with offer repair and replacement services and will have your windows and doors looking as good as new.

Repairs can be carried out on broken locks, broken internal beading, condensation trapped in windows, misting and cracks or dents in frames.

Sometimes, however, a repair job is not appropriate and the unit will need to be replaced. We work with honest companies, which means they would never suggest you get a replacement if they thought that a repair would be possible.

How Much Does it Cost to Install Double Pane Windows?

When you receive an online quote, consult our price tables or use our online cost calculator, the price you receive will be the cost of the windows including installation. This ensures that you will not be hit with additional surprise costs further along in your installation.

If you would prefer, we do work with supply-only window companies, which means that you can have the windows delivered and install them yourself.

Ultimately however, installing your own windows can be a difficult and time consuming activity. You will also have to deal with the building regulations which your installer would normally sort out on your behalf. The savings made from purchasing supply only windows are not always necessarily worth the trouble of installing them yourself.

What Is The Cost of uPVC Windows Fitted?

We give prices in our quotes, pricing tables and cost calculators that include the cost of installation as standard. As such, for a small, white, fitted casement window, the guide price of £150-£175 covers the cost of installation as well as the cost of the window itself.
