Wall Building FAQs

Do I need planning permission for a wall?

Not always. Walls under a certain height usually don’t require permission, but taller or boundary walls might. We’ll let you know if approval is needed.

How much will it cost?

Costs depend on size, materials, and site conditions. We offer free site visits and no-obligation quotes so you know exactly what to expect.

How long does it take to build a wall?

Most garden or boundary walls are completed within a few days to a week. Larger or more complex walls may take longer.

What materials can you use?

We work with brick, block, and stone. We can match your existing walls or recommend durable, attractive options to suit your property.

Will the wall have proper foundations?

Yes. Every wall we build includes strong, well-prepared foundations to ensure long-term stability.

Can you remove my old wall first?

Absolutely. We’ll safely take down and dispose of your old wall before starting the new build.

Do you guarantee your work?

Yes. All of our walls are covered by a workmanship guarantee for your peace of mind.
