Local or National Double Glazing Installers?

Both! It’s best to consider both national and local double glazing installers for your home renovation project, or if you’re just updating your home. Get quotes from both local and national double glazing installers and compare which quotes fit within your budget.

Whilst double glazing cost is important, so is the support you receive throughout the project from start to finish.

You might prefer a local company so that you can have more of a personal service, although you might prefer a national company who can simply get the job done and treat is as any other job.

However, national companies may run promotions and discounts from time to time, financing options are more available from national companies. These could save you costs overall, whereas, you might be paying more top level prices for a smaller company but the level of personal service you receive could be greater than that of a national company.

The same variables apply, you may get charged extra for style, design, finish and other accessories. Customisation can also be quite costly and bump up the price. But as long as you have budgeted for these options with a realistic figure, then you should be fine.

As with new double glazed windows, replacement windows can also be quite expensive and is a competitive market. So it’s best to find multiple quotes from different companies in and around your area, then, compare those quotes from national quotes which you could enquire about.

By doing so, you get the best price available for your budget and your project.

Comparing Double Glazing Prices

Researching has never been more important than it has in the home improvement market. It will make you more in-tune with double glazing prices and put you in a better position to be able to buy double glazing windows at a competitive price.

Furthermore, your knowledge of the different types of window styles and designs will improve as you get to understand the different costs for the different styles.

There are many things to consider when buying double glazing, these include;

Energy Efficiency Ratings

In the long run investing into high energy rated double glazed windows can reduce energy costs and in turn save you money, but upfront they are likely to be more expensive.

Double glazed windows are ranked on a simple grading scale with G being the least energy efficient and A++ being the most energy efficient. So when shopping around, consider budget but also consider energy bills for the next 10 years plus as you will more than likely be keeping your windows for that amount of time at least. This is why we would advise on spending a little more money to get the A++ energy rated windows.

Types of Glass and Colours

The type of glass you choose to install with your windows will also impact the double glazing cost. Whether you go with toughened, frosted or self-cleaning, they each come with benefits and each add to the cost of your double glazing. Although in some cases, the toughened glass may be a requirement. In such cases, it’s best to speak to your installer for specifics and any other questions you have, as they will be able to best advise you on what to do.

The colour of the frames will also bump up the price. White is the most popular,  however there are many colours to choose from. Contemporary colours such as black, grey or green are available to use. There’s even different effects and finishes such as the wood effect which can look nice but comes with a higher cost.

Accessories and hardware is also available for your windows. Different types of handles, colours and styles to suit your property rather than look out of place with the rest of your house.

It’s best to compare prices and quotes of different double glazing companies to make sure you’re getting a good deal. Then if you already have the budget at your disposal you can look at installing your new or replaced double glazing windows. If you need to look at other alternatives,  a lot of companies provide schemes such as financing options which include monthly instalments to pay for double glazing and other financing repayments. Be sure to find these out so that you know what’s available to you.

How Much Do Replacement Windows Cost?

For something such as a standard single double glazed replacement window, you may be expected to pay between £200 – £500. This is quite vague due to the amount of options there are.

Specification, style, size and other variables will increase the price for replacement windows and sometimes, you have to accept these price increases because of the style of your other windows.

If you have Georgian bars for all your other windows in your property, then you more than likely need to include Georgian bars in your new windows so they don’t look out of place.

Most manufacturers offer a 10 year guarantee on all their double glazed units as generally, this is the lifespan of units.

You may need to replace failing units in the meantime or if a quick and cheap double glazing fix is what you’re after, whilst this may fix the issues, long term you may run into more problems. Instead, look at comparing quotes for repair costs and replacement costs.

In retrospect, you may find you can afford to make these changes rather than a short term quick fix, such as a double glazed unit. It’s best to research and look around – with a budget in mind – to see if replacement windows is affordable to you.

Sash Windows Prices

As with all uPVC products, prices will vary according to the style and design of the windows. For a full breakdown of pricing and costs, see the table below.

Taking a traditional design such as sliding sash windows as an example, because it’s more difficult to manufacture, the price will then be more expensive than a casement window, which takes quicker to make. Then consider replacing the whole house with sash windows and the price will go up and be more expensive.

Customers frequently ask, how much is it to double glaze each window separately? Well, the size of the unit will ultimately decide the cost of the unit. However, we would advise creating several quotes for different styles and then, getting quotes from various companies to find the best prices available.

Aluminium Windows vs uPVC Window Prices

Overall uPVC windows are usually cheaper than aluminium windows. This is primarily down to the fact that the materials cost less. And this is why it’s popular with homeowners because of the material which costs less than other materials.

Purchasing new double glazing windows is a big investment which is why it’s important to choose high quality uPVC windows for your home. These windows will come with a warranty for 10 years as that’s how long they usually last before you might want to start thinking about renewing and replacing your uPVC windows.

uPVC windows are the main choice for residential properties as they are stylish, enhancing the look of the home as well as being relatively affordable for homeowners.

With many customisation options to choose from including styles, colours and materials, prices can rise, so be sure to shop around for the best quotes possible.

You will usually find that aluminium windows are more common in commercial properties. Speak to your double glazing supplier for more information regarding aluminium windows prices.

Does Window Material Affect The Price?

The material of the frames is one of the most important factors when determining the price and is dependant on the material. There are three base materials in the U.K. to choose from – uPVC, wood and aluminium.

Each come with their own pros and cons, but for the consumer, the price is the most important consideration to make to see what you can afford, at the very least, most people will be able to afford uPVC and this will generally be the most popular choice anyway because of the stylish, contemporary design which improves the overall look and quality of the home.
