Sand mastic for homes and businesses in Batt's Corner
On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant, and we will talk through which suits your home. We work on stone surrounds, period & listed homes and timber door frames, and people most often call us about modern sealant on a period surround and cracked mastic round a front door frame.
Somewhere as small as Batt's Corner, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
Whatever the size of the job, it’s backed by our 12-month guarantee in Batt's Corner and across Surrey.

Why deal with it now?
Before painting the windows, it pays to renew the mastic. Painting over failed mastic does not seal it, and the new mastic is traditionally left unpainted. Where a wall is exposed, as many are in small places like Batt's Corner, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

What affects the cost of sand mastic
The quote reflects the job in front of us. We take into account:
- Which sealant suits the joint
- The size of the job
- Any mould that needs treating
- The number of rooms or windows
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- The problem you’ve noticed
- Where the job is, and your postcode
- The type of property
- Photos by email, if that’s easy
For a quote, ring 0345 464 0079 or drop us an email with the location and a short description of the problem. You will have a clear quote before work begins.
DIY versus a professional finish
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
Windows and doors in Batt's Corner
Historic houses like Farnham Castle (about 4 miles north) are a reminder that the area around Batt's Corner has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. 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.
If you let a flat or house near Bentley (Hampshire) station, older sash windows in a rental need their mastic kept sound to keep the weather out. For an older house near a landmark such as The Church Of The Good Shepherd, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
