Every extension leans on the existing house, literally. Getting the structural interface right is what keeps both the old and new parts crack-free.

Where extensions go structurally wrong

Differential settlement between new and old foundations, openings cut into existing rear walls without adequate support, and roofs tied incorrectly into existing structures cause most extension defects we’re called to. Good structural design prevents all three.

What we provide

• Survey of the existing structure the extension will bear on
• Foundation advice appropriate to your ground (including clay and mining areas)
• Beam and lintel calculations for the new openings
• Drawings and calcs for Building Control approval

Extension cracking after the build?

If an existing or new extension is cracking, we inspect independently, establishing whether it’s normal early settlement or a defect the builder should remedy, with a report you can rely on in any dispute.

Why an independent survey matters

We are an independent firm of structural engineers, not tied to any estate agent, lender or builder. Our only job is to tell you the truth about the building. Established in 1981, we have inspected thousands of homes across Leeds and West Yorkshire, and our reports are accepted by mortgage lenders, solicitors and insurers.

What you get

• A clear written report in plain English, with photographs
• A definite answer: is it serious, is it historic, does it need monitoring or repair
• Repair recommendations and, where needed, outline costs
• Fast turnaround, reports typically delivered within days of inspection

We survey across Leeds, Wakefield, Bradford, Harrogate and all of West Yorkshire, see all areas and services.
