Retrofit Double Glazing for Peterlee properties

Retrofit Double Glazing in Peterlee is rarely a catalogue job. The building stock is colliery terraces, Georgian Durham city stock and Pennine stone housing, so we expect variation before we ever pick up a tape. The exposure here is cold upland winters with heavy rainfall, which is exactly the condition that causes frost and saturation damage on unmaintained painted softwood. The part that matters is reworking the rebate so a sealed unit fits without bulking the section.

Manufacture only starts once the survey figures are agreed with you in writing. A quick call or a photograph of the opening is usually enough to get you a price.

One thing that catches people out here: Durham's cathedral setting carries World Heritage-level design scrutiny.
