Double Glazing Costs

Replacing the windows in your home will not only improve its aesthetic appeal, but also its security and energy efficiency.  In many cases it’s possible to cut fuel bills by anything up to 25% and, if you should wish to sell your home in the future, recently replaced windows can add real value to your home.

For these reasons choosing the right windows for your home needs to be considered as an investment in your home. If you have an older – possibly Georgian or Victorian – home, for example, you may find that modern uPVC, or aluminium, double glazed windows will not complement the remainder of the architecture. It is worth doing a little research in your area, looking at the different types of windows on similar properties before committing to one type over another.

Double Glazing Considerations

It can be difficult to estimate the cost of replacement windows because there are so many factors to consider.  Replacement windows range from economical uPVC to costly, finely crafted wood, and in quality of construction, and there can be dramatic differences in price as a result. Generally speaking, however, you can typically expect to pay between £300 and £800 per window, subject to any discounts, or special offers that may be available.

Double-glazed, or triple-glazed, replacement windows – and especially those filled with inert argon, or krypton, gas for extra insulation – are, unsurprisingly, more expensive. Making good of dry rot, or other damage, around existing window frames may add to the cost of replacement windows, as may window sizes that are non-standard. In the case of the latter, custom built windows or the enlargement of the existing window opening to accommodate a window of standard size are possibilities, but may, in turn, increase the cost by up to 100% per window.

It is obviously important to obtain a number of no obligation quotes for a double glazing project, but remember to look beyond the bottom line figure.  You should look at the company behind the quote, materials, etc. uPVC, for example, is generally considered to be a “cheap and cheerful” solution for double glazed windows, but some uPVC windows are cheaper in construction than others.

Mechanically fixed – that is, partially screwed together – uPVC windows, for example, may have a shorter lifespan than those that are fully welded. Inferior quality uPVC can also lead to distortion, leaking and discolouration in a relatively short time, so the cheapest solution is not necessarily the best.

One method of saving money on double glazed windows is to purchase the windows from a home improvement outlet and have them installed by a local handyman or builder.  You need to ensure your installer is sufficiently competent – and aware of the requirements with regard to moisture, weatherproofing, etc. Many established replacement window companies, on the other hand, offer a comprehensive, 10-year guarantee on their products and this is the preferred route for many homeowners.
