FREQUENTLY ASKED QUESTIONS

Please reach us at

if you cannot find an answer to your question.

Will you handle planning permission / building regs?

Our teams can assist with what you require for your planning permission and can liaise with structural engineers to provide building regulation compliance.

How do you ensure the glazing integrates cleanly with new extensions?

We plan all junctions carefully (lintels, flashings, seals) and use compatible profiles / systems to ensure there’s no weak point or leak.

What timelines are typical?

Depending on the scale — a small orangery might take 8–12 weeks, a full extension could be 4–6 months. We provide a project schedule during quotation.

Can you match existing styles/materials?

Absolutely. We aim to blend new work with your property’s character — whether masonry, cladding, window style, etc.

What warranties or guarantees do you provide?

We stand behind structural work, glazing, and finishes. We’ll outline warranties in your contract and offer maintenance support.
