Retrofit Double Glazing for Durham properties
Half the Retrofit Double Glazing problems we fix in Durham started as a sizing assumption. Local property is overwhelmingly colliery terraces, Georgian Durham city stock and Pennine stone housing, which is why we never quote from a catalogue. Add cold upland winters with heavy rainfall to that and frost and saturation damage on unmaintained painted softwood becomes the usual trigger for replacement. In practice that means reworking the rebate so a sealed unit fits without bulking the section.
We check on site before committing anything to the saw, and we query what does not add up. We will price it properly in writing, and we will tell you if it is not worth doing.
A local consideration we always raise: Durham's cathedral setting carries World Heritage-level design scrutiny.
