A well-planned window replacement seems to have benefits only: it can improve your home’s energy efficiency, security and appearance while reducing exterior noise. The only disadvantage is the fact that it is not the cheapest of home improvement projects. Since the average cost of window replacement is generally high, it would be helpful to estimate window replacement quote before the whole undertaking, right? No window replacement is exactly the same and costs can differ from project to project. Obviously, prices vary depending on the window material, size, number and the fact whether it is a new build or a house renovation project. Whole house window replacement cost would be much higher than one window replacement cost – that’s as clear as a bell. So how much does typical window replacement cost? We hope this article will help you determine house window replacement prices once and for all!

Is it cheaper to replace windows yourself?

Before we go on to discuss the average cost of window replacement, let’s focus on the answer to one of the most common questions our customers ask: is it worth it to install your house windows on your own? Is it a solution for a cheap windows replacement? Well, we have devoted one full blog post to this subject HERE, but let us sum up the most important issues here once again. 

Generally, we think that professional window replacement gives you peace of mind knowing that your installer has experience and expertise to get the job done right. Hiring an experienced window fitting team is simply an assurance that your new windows will be installed properly and last in your home. Even the highest quality windows may fail if they are not installed correctly. Incorrect window installation may result in drafts, which make your home less energy-efficient, and water infiltration, which can cause rotting in your window frames. All of these will result in future costly improvements – and it’s not what you’re hoping for, is it? That’s why in order to eliminate all the possible window installation mistakes and additional costs simply leave this job to professionals. What is more, hiring a professional window fitting team gives very valuable peace of mind – and that’s as important as a window replacement quote! At Fenbro, we offer a full 2-year warranty for installation performed by our fitting teams. We take full responsibility not only for the correct dimensions of the ordered products but also for the quality of the window and door installation or replacement service. 

But how to make sure you choose a trustworthy window fitting team that provides window cost and installation you’ll be satisfied with? Read on to find out!

 

Qualities all good window installers should have

At Fenbro, we understand the importance of selecting the right professionals for the job. And what’s more, we know how to deliver outstanding window replacement services. If you want to know more about our professional fitting teams in Ireland and the UK, go to THIS page and take a look at our impressive realization projects HERE

One of the most important qualities to look for in a window fitter is experience and expertise. Installing windows is clearly a skill that requires thorough knowledge of various window types, materials, and installation techniques. Every home has a unique design and owners have specific expectations, a good window installer must know how to pay close attention to detail. Professional window fitting teams use only high-quality materials and joinery products and will always tell you which windows are worth investing in. They can suggest the best brands and solutions that would be the most suitable for your property, as well as for the climate you live in and weather conditions. 

Secondly, professional window installation teams offer complex services. Obtaining the proper window measurements, removing the old window, installing the new one and sealing the opening correctly after the installation should obviously be the most crucial elements of their offer – as well as effective communication. Good window installers should always inform you about the progress of your project, answer your questions and work respectfully in your home. Demonstrating confidence in the quality of their work and providing homeowners with peace of mind are crucial for a smooth window installation process. Go to our Reviews to learn why Fenbro customers appreciate our fitting teams so much! 

Last but not least: certificates! Always ask your chosen fitting team not only about window replacement cost and replacement windows prices but also about proper certification, like the FENSA certificate in the UK or Building Control in Ireland. They are a declaration by the installation company to the homeowner that the windows they have replaced provide safety and required performance standards. If you want to know more about all the necessary building regulations in the UK and Ireland, go to THIS blog article. 

How much does it cost to replace one window in the UK or Ireland?

Frankly speaking, it is impossible to give one specific cost per window replacement. While installing windows in a newly built building is generally quite simple, estimating the average price to replace windows in e.g. an old English single-family house can be quite challenging. This is primarily due to the fact that the installation work in this case is more extensive and may include, for example, the need to widen window openings. In the Fenbro offer, new windows installation cost or typical window replacement cost differ vastly. While installing 12 uPVC windows in a new build costs €1,950, replacing 8 windows of the same model and type in a house renovation project is priced at €2,520.  In general, in order to estimate window replacement cost you have to know replacement windows prices. In case of more expensive aluminium windows, window replacement cost of 14 items amounts to €5,940. If you want to know how much new windows cost, go to one of our latest blog articles HERE. 

However, the final cost of replacing and installing new windows may be influenced by many other different factors such as:

  • number of windows – single window replacement cost is nothing compared to replacing multiple windows in your home at once;
  • material of window sashes (uPVC window replacement cost is different from the aluminium one);
  • window size – a small window in your bathroom will cost less than a large living room window;
  • type of a building project – there is a difference between new window installation cost and window replacement cost:
    • in case of a new build, the prices start from €25 per window linear metre
    • in case of renovation, it is about €50 per window linear metre
    • in case of renovation with finishing (the so-called  plastering of window reveals) the lowest price you’ll pay is €55 per linear metre
  • method of window installation – in case of the so-called warm installation used mainly in new build projects, new window installation cost may increase up to 3 times depending on the type of tapes and insulation materials used to seal the connection between the window and the wall;
  • the need to carry out preparatory work;
  • the level of complexity of post-installation processing;
  • location – the cost of window installation may vary depending on the region in which you live.

The average cost of window installation is approximately € 30 per linear metre (for new build), with the highest prices for the installation of roof windows (approximately € 40-120 per linear metre). The given rate should also include the cost of carrying out additional works, including: dismantling the old window frame, which can cost up to € 60.

How long does it take to replace and install a window at home?

As you can see, window replacement cost has many variables. Aside from the above mentioned factors, there is also the actual labour time you need to consider before replacing your windows. When deciding to replace old windows and install new joinery, we must be patient because these works may sometimes take longer than it might seem at first glance. A standard window installation can take anywhere from a day to a week, depending on the size of your home and the number of windows that need to be replaced. 

Generally, the whole window installation or replacement process takes place in the following stages:

Measurement of window openings

Window installation specialists assess the technical conditions of installation and determine what parameters new windows should meet and what the size of window openings should be. At Fenbro, our fitters confirm the window opening measurements during the first visit at your home to check for potential errors and suggest some product solutions if you haven’t made your final decisions yet. If you want to know how to properly measure for windows and doors, check our very useful blog posts HERE and HERE.

 

Dismantling the old windows

In most cases, this part of work can be completed by our fitting team in one day, provided there are no complications related to the condition of the building.

Development of new window openings

This process usually takes up to several hours (mainly when a larger space is needed for the installation of new windows). 

New window installation

The actual window installation process can be completed within 0,5-1 hour. However, it is worth remembering that the installation of larger and more complicated window systems may take slightly longer. Of course, if you decide to replace every window in the house, it may take up an entire day.  

Insulation

Insulation and waterproofing may be necessary depending on where you live (coastal areas, regions subjected to the extremes of the British weather, etc.). This typically includes filling the gaps around the window frame to prevent air or water from getting in. The working time here is about 30 minutes per window. Generally, it is assumed that labour related to replacing old windows and installing new ones should not take longer than 2 days. However, this is an estimated time and depends on how many elements are assembled and how much time is needed to dismantle the old window joinery.

Worksite cleaning 

Once the installation work is done, window installers should remove any work-related waste and leave the construction area clean. To be honest, this service is what differentiates top-quality window fitters and installers from the poor ones. Fenbro fitting teams always secure disposal of old windows (we order a skip for garbage) and clean the work areas inside and outside our customers’ home and take away all job-related debris. In the end, we always clean up after ourselves so that there is no trace of our visit. Obviously, the worksite clean-up should be included in the overall window replacement cost. 

Ask for online window replacement quote!

It is clear now that in order to estimate window replacement cost we have to take many different factors into account. Obviously, it is always worth carefully examining the various options and price offers to find the best solution for your needs. Remember that proper installation of windows translates into thermal and acoustic comfort of your household members and savings in heating and electricity bills.

Don’t hesitate to contact the Fenbro Sales Team if you want to transform your home by installing windows that enhance its appearance and energy efficiency.
