Retrofit Double Glazing for Farnham properties
The hard part of Retrofit Double Glazing in Farnham is not the making, it is the measuring. With interwar detached stock, Arts and Crafts houses and 1930s semis making up much of the area, off-the-shelf sizes rarely line up. mild but damp, with heavy tree cover holding moisture against elevations is the local complication, and sap staining and green growth on north elevations followed by joint opening is what it eventually causes. The detail we will not compromise on 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. One call is usually enough for us to tell you roughly where the price will land.
Something particular to this area: high-value stock where owners specify hardwood over softwood as standard.
