Sand mastic for homes and businesses in Southover
Traditional burnt sand mastic that sits naturally against stone and brick. It suits period and listed homes, where modern sealant can look out of place.

Around Southover, conservatories, garden rooms and patio doors are often part of the house. Their glazing joints and frame seals are as much a part of the job as the windows, and any older timber or sash windows need a sealant that suits them.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
What happens on the day
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to a full day, depending on how many windows. Parking around Southover is generally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic is not too thick.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Try not to wet indoor joints just before the visit
- Move anything stored near the joints

Why it’s worth doing now in Southover
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic suits the building and blends with the stone or brick. Around Southover, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
The cost reflects the work involved, not guesswork. That is why we ask about the job first and agree the price before starting.

Where is Mr Mastic based?

Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Can you replace silicone on a period window with sand mastic?
Often, yes. Once the silicone is out and the joint prepared, sand mastic is applied by hand.

Most of the time, yes. We’ll tell you which colours the right product comes in and agree one before we start.
Can you seal over the old sealant?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.

What sand mastic looks like in Southover
With historic houses such as Anne of Cleves House (about 0.2 miles south-west) nearby, there’s older building stock in the area around Southover as well as newer homes. 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. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you look after a building such as Western Road Community Primary School, the mastic around its windows and doors needs looking after like any other building’s. For landlords with property near Lewes station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Do you need sand mastic in Southover?
Scraping and sanding before painting can loosen old mastic. It’s often found when windows are being prepared for paint, which is a good time to renew it.
It’s worth asking for a quote if you see:
- Gaps round a timber door in stone or brick
- Old cement repairs round a window that have failed
- Gaps between timber frames and stone or brick
- Draughty sash windows at the surround
Homes close to Church of St Michael include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
