Harrow is largely 1920s and 1930s Metro-land housing, with older properties around Harrow on the Hill and Pinner. It sits on London Clay, so clay shrinkage near trees and hedges is a common cause of cracking, and many homes have been extended, converted or had walls removed over the years. We regularly work in HA1, HA2, HA3, HA5 and HA7.
Common reasons clients in Harrow call us
• Cracking linked to London Clay, trees and hedges
• Movement in bays and older extensions
• Loft conversions and hip-to-gable extensions
• Rear extensions and wall removals
• Pre-purchase checks after a RICS survey flags a concern
Because we also design drainage, we can identify when a leaking drain is behind the movement and design the fix.
Local questions
Can a hedge cause cracking?
Yes. Large hedges, especially fast-growing conifers, close to a house on London Clay can dry the ground as much as a tree. It’s a common cause of cracking in Harrow, Pinner and Kenton.
I want to extend my 1930s house in Harrow, but it already has an old extension. Can you help?
Yes. We check the existing extension’s structure and foundations first, as they often need strengthening or rebuilding before you build on or alongside them.
Guide prices: specific inspection of one defect £950 + VAT, general inspection of the whole property approx. £1,700 + VAT.
12+ years’ experience · £1,000,000 PI insurance · Site visit within 3 working days · 48-hour reports
