FAQs

What is Tanalised timber?

The process of tanalising involves pressure treating timber with Tanalith E wood preservative. The hydraulic pressure forces the preservative deep into the wood.

Does tanalised timber need maintenance?

Yes, we recommend the use of a high-performance oil-based treatment.  We offer our own high-performance oil-based treatment which is available to buy in tins or we also offer a service where we apply the oil in our factory prior to your building being installed.  The use of water-based treatments is not recommended; please note that no liability will be accepted if the incorrect type of treatment is applied to the building.

Do the buildings come with a floor?

Yes, all of our buildings come with a floor, however, all buildings will also require a base which is not supplied as standard.

What type of base is required?

A solid, flat, level base is essential – an uneven base can result in the building twisting, which will affect the ability to open and close doors and windows. Flagstones, concrete, or slabs are good options, or we offer Tanalised Timber Airtech bases; these are an excellent choice as they suitable for use on any surface.

What access is needed to install my building?

Fair and reasonable access must be given on the day of installation.  Please bear in mind that all sizes are external but do not include the roof/overhang, please allow at least 6-8 inches all the way around the building for the roof overhang.  Please check any obstacles that will prevent access, including height and width. Certain size buildings will not fit through a standard house door, through a ginnel or under an arched gate for example. We can manufacture buildings in modular form for tight access at an additional fee of 20% of the overall cost of the building.  We do NOT under any circumstances carry buildings over roofs, carports, outdoor buildings, fences, walls or over long distances due to insurance purposes.  It is your responsibility to inform us upon ordering, of any issues regarding access to your garden.

What size vehicles are used to deliver my building?

We use 3.5 tonne Ford Transit flat-bed vans.

Do you have buildings on display we can look at?

Yes, we have an extensive show site and we are open 7 days a week for you to come and view them.

Do you make custom builds?

Yes.  We would require a rough sketch of the building emailing to us, which includes sizes, window/door positions and any other information relevant so that we can give you a quotation.

What does nominal sizes mean?

Nominal sizes refer to timber size prior to machining. The finished size after machining is normally around 4mm less than the nominal size.

Are there any planning restrictions?

Planning restrictions may vary depending on where you are located and where the proposed building is going in the garden. The normal restriction is if the building is going within 2m of the boundary line then it needs to be below 2.5m to the highest point. We would always recommend checking with your local office
