Frequently Asked Questions (FAQs)
What is a Lean-To?
A lean-to is a garden structure that is installed against an existing wall or building. It typically uses posts and rafters that extend outward from the wall, creating a supported outdoor space that feels like a natural extension of your home.
What is the difference between a Pergola and a Lean-To?
A pergola can be either freestanding or attached, while a lean-to pergola is specifically designed to be fixed to an existing structure such as a house or outbuilding. Lean-to pergolas are ideal when you want:
-
A space-saving garden structure
-
More stability from wall support
-
A bright, semi-sheltered area connected to your home
This product is a lean-to pergola, meaning it must be installed against a wall and securely fixed.
Are the pergola components pressure treated?
Yes. All timber components are fully pressure treated, helping to protect the wood from rot, moisture, and decay. This significantly extends the lifespan of the pergola and keeps maintenance low.
(Roofing materials may vary depending on the option selected.)
Do you make bespoke pergolas?
Yes, we do. We offer fully bespoke pergolas, tailored exactly to your required dimensions and layout.
For a custom quote, contact our Sales team.
Can I install a pergola without planning permission?
In most cases, planning permission is not required for a pergola, provided it meets permitted development rules. These rules can vary depending on location, property type, and size of the structure, so we always recommend checking with your local council before installation.
Installation FAQs
Does the lean-to pergola arrive fully assembled?
No. The pergola is delivered flat-packed for safe transport. However, detailed step-by-step assembly instructions are included, making installation straightforward for competent DIYers or professional installers.
Are fixings included?
Yes. All required fixings are included with your pergola components, so you’ll have everything needed for installation.
Please note: the pergola must be securely fixed to the ground and wall for safety and stability.
Aftercare & Maintenance
Can I paint my pergola?
Yes, the pergola can be painted.
-
Only water-based paints should be used
-
Ensure the timber is completely dry before painting
-
We recommend applying a UV protection treatment prior to painting for best results
What maintenance is required?
To keep your pergola in excellent condition, we recommend:
-
Treating the timber every 6 months with Osmo Oil
-
Periodically checking fixings and joints
-
Cleaning away dirt, moss, or debris to prevent moisture build-up
Regular maintenance will significantly extend the life of your pergola.
How long will the pergola last?
With proper care and regular treatment, our wooden pergolas can last between 10 and 20 years. Pressure-treated timber combined with routine maintenance ensures long-term durability and performance outdoors.

Help with my new garage roof!
Trade Warehouse could not have been more helpful. They very patiently guided a roofing newbie through all of the stuff I would need to do the job and provided helpful tips along the way. It's rare to find a company offering such a fantastic level of customer service as standard. I would highly recommend them and will certainly use them again.

Garden Storage
My contractor (Charlie Keep) recommended you to me so I could order the materials online for delivery direct to my home. These were for a project to construct a Garden Storage Area. The materials were perfect and the whole process was simple and slick with materials delivered on time and very well packaged. Charlie has since completed the project & I am very happy with the outcome.
