A bespoke oak porch means the installation and maintenance may differ.

This guide gives help on understanding these areas.

Strictly speaking, the oak on your oak porch doesn’t need maintenance.

Oak is a very robust timber and can handle most weather conditions for years to come.

When you decide on having an oak porch, it can be coated with an exterior UV oil, normally in a choice of clear, natural (golden) or traditional (a darker oak).

Over time, the weather, especially the sun, will react with the oil and break it down.  This may happen several months or years depending on which direction your oak porch faces and the amount of sun it receives.

You now have a choice.  When you see a slight discolouration in the oak, a more silvery grey appearance, you could apply another coat of external UV oil or allow the oak porch to weather naturally.

This colour change is not detrimental to the oak.  It is not a sign of rot and is purely a natural change in colour.

The change is a reaction between the UV rays of the sun reacting with a naturally present acid in the oak called ‘Tannin Acid’.  This reaction causes the oak to turn silver grey.

It is personal choice how who you want your oak porch to look in the years that follow.

A full installation service can be provided depending on your location.

Your oak porch should be installed by a skilled joiner.  Although not complicated, attention to detail and the weight of the oak should be considered before attempting installation.

The majority of oak porches will be delivered in already constructed and jointed sections.

The [tipso tip=”The triangular oak structure that sits on the legs to create the roof.”]oak truss[/tipso] arrives complete and therefore only needs to be lifted into position.

The side walls are also constructed and need aligning vertically against the house wall.  These need installing using [tipso tip=”A large metal screw designed for attaching timber to masonry.”]frame fixings[/tipso] and provided oak dowels.

At the base of the legs, there are [tipso tip=”Stainless steel is used as normal steel reacts with the tannin acid found in oak beams”]stainless steel[/tipso] pins designed to be located in the stone flags, concrete pad or brick sets on the floor.  The pin protrudes 70mm and is designed to sit within a 60mm deep hole.  This will enable the leg of your oak porch to sit 10mm proud of the floor to encourage rainwater to drain away.

Other components are loose, for example, the common rafters (These are the intermediate diagonal pieces of oak situated between the front truss and the wall of your house. They create the roof structure) and curved brackets and have all been pre-assembled knowing everything fits together.  These final items are simply screwed into place.
