How To Prepare Your Oak Building For Winter

As each year closes, knowing how to prepare your Oak Framed Building for winter is crucial.


Although Britain may not experience the harshest winters in the world, our weather conditions can still put Oak buildings at risk. The seemingly relentless rain, snow, frost and driving cold winds can all take their toll.


Proper preparation could save your serious money in the maintaining and care of your building.


Whether this is from reduced heating costs or avoiding costly repair jobs in the spring, now is the time to act.


Luckily, most of these methods are preventative and easy for the owner to carry out without professional help. All apply equally to newly built Oak Frames, Extensions and Garden Rooms or established structures standing for many years.


By following the steps outlined below, you can be sure your property is ready for the worst that winter can throw at it.


1. Treating Exterior Oak

Oak is perfectly suited to exterior use as its natural resistance to water penetration means the British climate will cause little harm.


Some owners prefer to keep the original colour rather than allowing the natural silvering that comes with age.


This can be achieved by applying clear wood preservative followed by UV protection oil.


Most Oak preservatives will need to be refreshed every 12 months and the perfect time to do it is late summer/early autumn.


Treating exterior Oak for blackening from water reacting to tannins in the timber should also be done during these months. Wet winter conditions will only make watermarks worse and will make treatment almost impossible.


2. Protecting Outdoor Furniture

In gazebos or summerhouses with fitted benches, simply covering them with waterproof sheets can prevent build ups of snow or rainwater.


Freestanding benches and other furniture secured to the ground can be similarly protected.


Any unsecured wooden furniture can be stored in garages or sheds until springtime if space is available.


3. Clearing Guttering

During the summer, plants can grow in the guttering of your Oak Framed structure.


Obscured from view and in the autumn, leaves can accumulate, blocking the flow of water. Left unchecked this can cause overflows during heavy rainfall or when snow thaws. Thus leading to blackening and encouraging mould.


Clearing any debris from guttering before winter allows water to flow freely away from Oak roofing and Cladding.


Standing water in prolonged contact with Oak can cause dry rot if the moisture content of the timber rises above 20%.


This can spread to other structural elements of the building, causing massive damage.


4. Clearing Debris from Floors

Leaves and dirt that have built up at the base of Oak structures can retain water, making this more likely. Clearing them away now allows the Oak to remain as dry as possible during winter.


Freestanding Oak structures are often secured to concrete footings with steel fixtures to leave a gap to avoid this. However, wet debris collected around these can also lead to rusting that will weaken the overall structure.


5. Checking for Damage

Over the course of the year, Oak Cladding or roofing on outdoor buildings can suffer minor damage that goes unnoticed. In the winter, this can allow cold winds to penetrate houses, increasing heating costs.


Water can also flow through any cracks or holes, causing damp that can damage the structure and contents. If this freezes, it will expand, widening the gap and further damaging the timber.


All exterior timber should be visually inspected for damage and repaired if necessary to avoid these issues.

6. Checking Window Seals

As the Oak around window fittings shrinks over time it can create gaps and compromise the seals. While this should be factored into the design of new buildings to prevent gaps, it may be an issue in older structures.


Again, this can drive up heating costs and allow water to penetrate the building. Any gaps can be easily remedied by applying clear silicone sealant to prevent rain or snow entering.


With our full Oak Capping Systems, this should never be a problem with your Oak Framed structure.


7. Insulation

Oak has a lower thermal mass than many construction materials. Therefore Oak buildings lose less heat in winter and warm up quickly.


However, additional insulation will be necessary. For contemporary Oak Framed Houses there are a wealth of options for wall insulation, from structural insulation panels (SIPs) to synthetic foam boards and natural fibre wools.


In older Oak buildings, tearing open walls to fit modern insulation is impractical, time consuming and expensive. Loft insulation is one possible solution to this. As heat rises, a huge amount can be lost through an uninsulated roof.


Solving this can be one of the best energy saving improvements you can make.


Mineral wool rolls are readily available, relatively cheap and easy to install. Insulating the interior surface of the roof and between the rafters of the loft will dramatically reduce heat loss.


Just following these simple steps will go a long way to keeping your Oak Framed building cosy in winter.


Combined with the natural hardiness of oak they should ensure years of trouble-free winters protected from the elements.
