Sand mastic in Elvendon: local notes
With historic houses such as Basildon Park (about 2.1 miles south-west) nearby, there’s older building stock in the area around Elvendon as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For landlords with property near Goring & Streatley station, older sash windows in a rental need their mastic kept sound to keep the weather out. Historic houses such as Basildon Park, about 2.1 miles south-west, show how far back building around Elvendon goes.

How we handle sand mastic in Elvendon
Sand mastic skins over fairly quickly, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted, so ask us before you decorate. We are often asked to deal with old sand mastic that has cracked, crumbled or fallen out and gaps between timber frames and stone or brick, across tenement windows, sash and case windows and stone surrounds.
Mastic can only go onto a dry, clean joint, so window work in Elvendon is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
All our work is covered by our one-year guarantee, wherever you are in Oxfordshire.

Why act early in Elvendon
Before painting the windows, it pays to renew the mastic. Painting over failed mastic doesn’t seal it, and the new mastic is traditionally left unpainted. Older cottages and farmhouses around Elvendon can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
