How the job changes by surface
Sash and case windows
Sash windows are where we do most sand mastic work. We renew the mastic round each box.
Timber door frames
Sand mastic is used round timber door frames too. The method is the same as for windows.
Sand mastic in Highbridge, done properly
Sand mastic skins over fairly quickly, but it takes longer to harden fully. Traditional guidance is not to paint over it, so ask us before you decorate. Common call-outs are for window mastic to renew ahead of painting and mastic worn away on windows facing the weather, on brick reveals, period & listed homes and sash and case windows.
Mastic can only go onto a dry, clean joint, so window work in Highbridge is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
You get a 12-month guarantee, the same in Highbridge as everywhere else we work.

What else we do in Highbridge
Landlord and commercial work in Highbridge
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
We work for landlords and agents as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.
Why deal with it now?
Filling over old, loose mastic doesn’t last. We remove the loose material first so the new work lasts. Older cottages and farmhouses around Highbridge can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Combining jobs into one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will give you a clear price for the lot.

Advice
Do you need sand mastic in Highbridge?
Decorating can disturb tired mastic. Many people find it crumbling when they prepare the windows.
It’s worth asking for a quote if you see:
- Mastic dropping out of the joint
- Weathered mastic on the most exposed windows
- Draughty sash windows at the surround
- Gaps round a timber door in stone or brick
Rented homes near Eastleigh station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.

What sand mastic looks like in Highbridge
With historic houses such as South Stoneham House (about 4.2 miles south-west) nearby, there’s older building stock in the area around Highbridge as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For an older house near a landmark such as St Mary's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Managing a site like Colden Common Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.

If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Highbridge: your questions answered
Do you work for landlords with property near Eastleigh station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear price.
Will you come out to Highbridge?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
How much does sand mastic cost in Highbridge?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we will talk you through it.
Is it possible to take out silicone and use sand mastic instead?
Yes, it’s a common request. The old silicone has to come out completely so the mastic can sit properly.
Can you quote for more than one area?
Of course. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
Where do you work from?
We’re a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
