How to maintain your Wooden Garden Sheds, Summerhouses and Log Cabins

  1. Check your base: With most wooden sheds and structures the key to maintaining the building is ensuring that it remains on a firm and level base and protected against moisture penetration, monitor this regularly. Any movement of the base under the building can lead to twisting of the timber or dropping of the doors.
  2. Seal your windows: It is essential that all windows are sealed inside and out as soon as is possible after assembly. This could be achieved via the application of silicone, timber beading or any other suitable ‘water tight’ solution at your own preference.
  3. Treat your building annually: Although it may come with a factory basecoat you should treat your new garden building shortly after installation with a good quality water resistant treatment. This process should then be repeated annually with care taken to brush the treatment into all wooden components involved within the construction of the building, inside and out.
  4. Ensure nothing is in contact with your building: Any overhanging tree or hedge growth poses a threat to your garden building and should be cut back at regular intervals. If a tree branch makes contact with your building it may pierce the roofing felt and encourage water ingress.
  5. Check and replace any damaged felt:  If you do find any damage sustained to your roofing felt over time it is essential that you act upon this without delay. Should you discover a rip or tear in the felt it is recommended that this area be stripped from the roof and a new covering of high grade, heavy duty, mineral felt (which can be purchased from all our branches) be affixed immediately.
  6. Ventilation: It is important to ensure adequate ventilation to your garden building as this will help to prevent condensation which could lead to deteriation of the timber, this is highly necessary when using as a workshop and may be advisable to fit an air vent.
  7. Lubrication: All hinges and locks should be lubricated with suitable oil to ensure continued ease of use.
  8. Conclusion: Our tips and advice offered above should help you keep that Garden Building in tip top condition and add value to any property.
