Slim Cavity Units for Heathfield properties

We take a fair volume of Slim Cavity Units work across Heathfield, and almost none of it repeats. Around here it is Regency bows and bays, weatherboarded cottages and cliff-top villas, and that alone rules out anything bought by the pallet. severe salt exposure combined with strong UV on south-facing frontages is the local complication, and UV breakdown of clear finishes and rapid degradation of putty lines is what it eventually causes. Our focus on this is narrow cavities that perform while keeping the sightline historic.

The site visit comes first, because assumptions made in an office get paid for on site. A quick call or a photograph of the opening is usually enough to get you a price.

A local consideration we always raise: Regency bow windows demand curved-glass and matched-profile joinery.
