Slim Cavity Units for Wellingborough properties

People come to us about Slim Cavity Units in Wellingborough once the cheap option has already failed. Because the area is mainly ironstone cottages, boot-and-shoe terraces and new town expansion housing, no two openings measure quite the same. 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. Where we put the effort is narrow cavities that perform while keeping the sightline historic.

We check on site before committing anything to the saw, and we query what does not add up. A quick call or a photograph of the opening is usually enough to get you a price.

One thing that catches people out here: ironstone reveals absorb water and hold it against frames in wet spells.
