Sand mastic in Kingsnorth
A silicone bead around a sash window can look out of place and does not suit the building. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. We work on period & listed homes, timber door frames and brick reveals, and the jobs we see most are silicone on a period window that looks wrong and mastic dropping out of the joint.
Somewhere as small as Kingsnorth, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
Our work is backed for twelve months, in Kingsnorth and everywhere else we cover.

Why act early in Kingsnorth
A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic suits the building and blends with the stone or brick. Older cottages and farmhouses around Kingsnorth can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
