When it comes to patio doors, unfortunately, there’s not a simple answer. There are several factors that will affect the cost of the project and the complexity of the installation involved. An obvious statement maybe, but the larger the doors the more glass and framing you will need which will increase the cost.
As a rough guide, sliding patio doors including 2-3 panels cost upwards of £400 on average. Bifold doors are more expensive starting from £1,000, increasing by around £1,000 for every additional panel. However, these figures do not include installation and will be impacted by several other factors.
Full installation or doors only?
Some of the more DIY experienced may feel confident enough to source their own doors and carry out the installation themselves. However, unless you are particularly experienced in this area you run the risk of poor installation which can lead to heat loss, damp or even doors that don’t work! There may also be building regulations to meet. If you then need to get a professional in to fix the job it’s likely to cost you even more money.
Our advice? Get a professional! A qualified and experienced installer will not only be able to carry out the installation but can advise you on the best materials, safety and security features and any building regulations you need to satisfy. The cost of installation will vary from supplier to supplier which is why it’s a very good idea to source quotes from multiple installers in order to compare their advice and costs.
The material you choose for your frame has a big impact on the final cost. The cheapest option is UPVC, followed by aluminium and then timber. It’s also possible to install composite frames which combine different materials. For example, you can opt for timber frames with an aluminium core to strengthen the structure. In addition to the cost of the material you also need to consider security, energy efficiency, ongoing maintenance and weather resistance.
How many panels / doors?
Sliding doors can be made up 2 to 4 panels and bifolding doors can include many more more. Each extra panel of glass and frame will add to the cost of the job.
What type of glass?
It’s really important to get the right type of glazing fitted and each different type has cost implications. Single is obviously the cheapest but not very secure or energy efficient. Double glazed is the minimum but if your budget can stretch further you can also upgrade to triple glazed, toughened glass or laminated glass.
Any finishing touches?
It’s possible to finish your frames in hundreds of different colours and finishes such as metallic and woodgrain, but this will increase the cost.
Any building work needed?
You may be creating a new opening for your doors or replacing windows. If this is the case there will be structural work in the surrounding walls that needs to be carried out in order to meet building regulations. This could includes damp coursing, plastering or introducing extra support like a lintel. This will add to the cost and should be carried out by a qualified professional.
Is there a guarantee included?
Are there any warranties or guarantees included on the doors and any of the fittings or security features? This may add to the initial cost but could be a huge saver in the long run.
