Retrofit Double Glazing for Porthmadog properties
What makes Retrofit Double Glazing work in Porthmadog is usually invisible once it is finished. Around here it is slate-quarry terraces, Victorian resort stock and stone farmhouses, and that alone rules out anything bought by the pallet. Because of severe Irish Sea exposure with very high rainfall, we see salt and rain combining to strip finishes and open glazing joints more often here than in most of the country. Where we put the effort is reworking the rebate so a sealed unit fits without bulking the section.
The site visit comes first, because assumptions made in an office get paid for on site. Get in touch and we will be straight with you about cost and timescale.
Bear in mind for this area: Llandudno's Victorian frontages are protected as a coherent conservation set.
