Your summer house will probably see a lot of activity in the warm weather. Whether you are about to open it up for the new season or you need to keep it in good condition over the winter, this guide provides the essential steps to maintain your wooden garden house lovely and fresh for when you’re ready to enjoy it.
Do Inspections on Both the Exterior and Interior
Regular inspections are crucial to catch potential issues early. Don’t wait for cracks in the walls or mould growth on the ceiling to appear. Make it a habit to inspect your summer house at least once a year to identify signs of wear and tear, and take action before small problems escalate into costly repairs. That way, you can take measures before issues get worse.
Begin by examining the base or foundation to see if it provides the stability you need. Next, check for leaks or holes, as these will allow pests to enter and water to seep in. Seal any openings you find, including on the windows and doors, with putty or wood filler. Allow the sealant to dry and harden up before sanding it flat.
Roof maintenance
The roof is one of the most vulnerable parts of your summer house and can suffer some wear and tear from harsh weather conditions. Inspect the roof regularly for damage, including worn mineral felt or shingles, and repair any issues immediately. After a storm in your area, check for damage caused by falling branches and debris. This is when the majority of damage occurs.
Tip: If you’re unable to perform the repairs yourself, we recommend hiring an expert to handle the task for you.
Ventilate the Summer House
While your summer house serves its purpose as a retreat to enjoy during summer, it’s important to let air out. As the weather warms up, you may notice more condensation building up inside. This routine helps control moisture, improve air quality, and deter pests.
Simply open the doors for a couple of hours regularly to allow condensation to dry out and dissipate, and maybe put a fan inside to help with airflow. When the summer house isn’t used during winter, you can come back in spring to find it musty or with a strong odor. Airing out also creates less favourable conditions for pests to nest and feed. Try to also remove anything which could be a source of humidity, such as plants, over the winter.

Treat and Paint your Wooden Summerhouse
Perhaps the most important maintenance task for a wooden building is treatment, which is achieved by painting it with either wood stain or coloured wood paint. If left untreated, timber can absorb moisture, leading to rot and damage. Prevent this and enhance your summerhouse protection by applying the right wood treatment. Do so as soon as the structure is installed, and repeat once a year for effective moisture repellence. It is important to apply a fresh coat even if you can’t see any gaps or flaking, to make sure water can’t possibly seep through. This maintenance is also crucial for upholding the manufacturer’s warranty on your summerhouse.
The best time to treat your wooden summer house is towards the end of summer, perhaps in early September, after the summer storms have finished but before the cold weather begins. This gives you the opportunity to do the job on a day where it’s still warm outside, while providing fresh protection ahead of when it’s most needed.
A fresh coat of paint or stain will also renew the appearance of your summerhouse, keeping it looking its best and enhancing its aesthetic value. You might as well do the same for the interior using these summer house paint ideas.
Tip: Consider investing in a pressure-treated summerhouse for less frequent re-retreatment. Read our guide, ‘How Long Does Pressure Treated Wood Last?’ to learn more.
