Slim Cavity Units for Gainsborough properties

People come to us about Slim Cavity Units in Gainsborough once the cheap option has already failed. Given the Georgian Stamford limestone, fenland farmhouses and coastal resort bungalows that dominates locally, standard sizes are the exception not the rule. Then there is low rainfall with severe exposed easterly wind off the North Sea, which reliably produces wind-driven rain ingress and sand abrasion on coastal finishes given enough seasons. Everything we do here comes back to narrow cavities that perform while keeping the sightline historic.

The site visit comes first, because assumptions made in an office get paid for on site. Send what you have, even if it is only a phone photo, and we will take it from there.

Worth knowing locally: Stamford is one of England's most tightly controlled conservation towns.
