Retrofit Double Glazing for Thrapston properties
Most Retrofit Double Glazing enquiries we take in Thrapston start with an opening that is not a standard size. Around here it is ironstone cottages, boot-and-shoe terraces and new town expansion housing, and that alone rules out anything bought by the pallet. Add dry inland conditions with limited coastal influence to that and seasonal shrinkage and glazing bead loosening on older painted units becomes the usual trigger for replacement. The detail we will not compromise on 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. Photographs and approximate sizes are all we need to start.
Bear in mind for this area: ironstone reveals absorb water and hold it against frames in wet spells.
