Retrofit Double Glazing for Northampton properties
Retrofit Double Glazing in Northampton rewards patience at the setting-out stage. 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. The other factor is dry inland conditions with limited coastal influence, which is why seasonal shrinkage and glazing bead loosening on older painted units is the most common reason people call us. Our focus on this is reworking the rebate so a sealed unit fits without bulking the section.
We survey before anything is cut, so the schedule reflects the opening as built rather than as drawn. We will price it properly in writing, and we will tell you if it is not worth doing.
One thing that catches people out here: ironstone reveals absorb water and hold it against frames in wet spells.
