Patio Doors

What the job entails

When it comes to renovating the rear of your property, patio doors are one of the most popular features in the UK. They offer convenient access along with great security, while opening up the room with natural light and garden views. The type of patio doors you can use depend on the size of the potential opening, design preferences and of course the available budget. Each type of door has their own benefits and patio door can be any kind of door that opens onto a patio or garden area, including the popular sliding doors, but also bi-folding and French doors too. There is much to consider when installing patio doors, with the costs being a major factor, but also you have to consider choosing a tradesman and dealing with possible planning permission and building regulations. Hopefully, this article will make the process much simpler.

Fitting patio doors will inevitably cause a lot of damage to both interior and exterior plaster, so make sure any quotes you relieve include repairing plasterwork. However, the quotes will not include decoration, which will also be required over the new interior plaster around the door frames. it may also be a good time to consider new double glazing if your windows are looking a bit grubby and faded - the brand new patio doors will make them look even worse! Painting the exterior may also be desirable for the same reasons, a dirty looking exterior will not look great with brand new shiny patio doors!

On a new build you have complete flexibility when it comes to choosing patio doors, but if you are just having new patio doors fitted, then your choices may be restricted as you have to fit in with the rest of the exterior windows (unless getting patio doors as part of a bigger double glazing job). French doors work well with smaller openings and you have the option to open just a single door for access during adverse weather conditions, yet when the sun is shining, you can open both doors wide and enjoy it. Traditional sliding patio doors move along on horizontal tracks in the floor so work well if space outside is restricted, so a good choice for small patio areas. Modern patio systems use up to 3 tracks so multiple doors can slide independently offering great flexibility. Bi-folding patio doors are the most popular design right now and they can truly open up your home with their fully opening operation.

Patio doors are not really a DIY project, you need, as a minimum, to at least consult an architect or structural engineer to determine the need for a lintel. Failure to add in the correct support could cause structural damage to your home. But if you have an existing opening, for example just replacing existing doors, then doing this yourself is feasible, but make sure you measure correctly, once the patio doors arrive made to your measurements you can't send then back!

If you are enlarging or creating a new opening for patio doors, you may need a load-bearing lintel installed as support. When comparing quotes, make sure this work is included in the price as a structural engineer or architect may need to be consulted and they will expect to be paid! If you do not get the correct advice, you could damage the structure of your home, and when it comes to resell time, you will have to remove the doors and insert the correct support in any case, at a much greater cost.

The Fitting Cost of Patio Doors

The actual cost of your patio doors could be completely different depending on your individual circumstances. So, the only way to get an accurate price is to get in touch with window/glazing specialits to measure up and provide quotations. Prices will vary depending on location, design, materials and dimensions.

The average material cost to fit patio doors will ultimately depend on the quality of patio door you choose to fit, how many you would like to fit or if it is double or triple glazed. Extra material costs may be incurred, such as, plastering materials or paint to tidy the edges of the new patio doors.

The average specialist will usually charge around £150 to £200 per day. The tradesman will usually work in pairs as some heavy lifting is required and they may sub-contract work if they themselves cannot do any structural or plastering work to finish the job. If you are modifying/creating an opening for patio doors to be fitted, you may need a load-bearing lintel installed. When comparing quotes between professional builders, make sure this additional work is included. In some cases, a structural engineer may need consulting, expect an additional cost of around £100.
