Unless you live in a conservation or heritage area, you don’t need planning permission to install a new patio door. 

However, any replacement doors are subject to building control regulations. This means that your new doors must comply with thermal performance and safety standards. 

Don’t stress though, if you hire a qualified installer, they will ensure your new patio doors meet these requirements. 

What and Who Do You Need?

There is a huge range of patio doors to choose from, but not all options are suitable for all homes. The last thing you want is to buy a new patio door that doesn’t fit or isn’t the correct type for the opening. 

This is why it’s important to consult a professional. A builder will be able to measure the patio door opening and give you a range of options that will work in the space. 

They’ll also be able to give you specific doors they recommend from reputable suppliers to ensure your new doors meet regulations and look fantastic. 

How Long Does It Take To Install A Patio Door?

The entire process takes less than a day to complete. Although it is possible to install patio doors yourself, you’ll get the best finish if you hire a professional who knows what they’re doing. 

Let’s take a look at how you install patio doors so you know what to expect:

The process of installing patio doors

1. Old doors removed

First, the old patio door is taken off its hinges and the frame is removed. Removing patio doors may require a reciprocating saw if the frame or door jamb are difficult to pop out.

2. Cill fitted

The cill is the first part to be installed. High-grade silicone sealant is used to attach it and give a waterproof seal. 

3. Outer frame fitted

Next, the outer frame is fitted using the same silicone sealant. Fittings are also used to attach the frame securely to the wall using a hammer drill. Once done, the handles and locks will be installed in the frame. 

4. Glass fitted

This takes at least two people since the glass is large and heavy to lift into place. If you’re doing it yourself, make sure you have someone to help you fit the glass. 

Beads and packers are used to keep the glazing in place. These need to be firmly pushed into place with a rubber mallet.  

What Should I Look For When Buying A Patio Door?

When it comes time to buy patio doors, there are several key factors to look for:

Type of patio door

There are many different types of patio doors, all with distinct styles:

  • Full glass sliding doors: modern, minimal and the most affordable. 
  • French doors: more traditional, country style, and slightly more expensive. 
  • Bifold doors: Ultra-modern, give the largest opening, most expensive.

Door frame material

Most patio doors are either uPVC or aluminium. These are two popular options, both with their own advantages:

  • uPVC: durable, low maintenance, low cost, but can degrade over time. 
  • Aluminium: extremely durable, low maintenance, looks modern, more expensive.

Colour

It’s important to think about both the interior and exterior of your home when choosing the best colour. Popular choices are white and anthracite grey, but there is a whole range of colours to choose from. 

White is the most popular because it goes with any style and interior palette. Although grey, black, or a bright pop of colour might look great from the outside, they can end up clashing with your interior decor if it’s more neutral. 

Consider the colour carefully and remember, your patio doors are going to last much longer than your interior colour palette, so make sure it’s a timeless choice.
