Retrofit Double Glazing for Grantham properties
Retrofit Double Glazing around Grantham is a different job from one street to the next. Most of what we survey locally is Georgian Stamford limestone, fenland farmhouses and coastal resort bungalows, which is not built to any modern module. Add low rainfall with severe exposed easterly wind off the North Sea to that and wind-driven rain ingress and sand abrasion on coastal finishes becomes the usual trigger for replacement. The part that matters is reworking the rebate so a sealed unit fits without bulking the section.
Each opening is recorded individually, since a terrace of identical houses rarely is. Photographs and approximate sizes are all we need to start.
One thing that catches people out here: Stamford is one of England's most tightly controlled conservation towns.
