Sand mastic for homes and businesses in Brimpton Common
Sand mastic skins over fairly quickly, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted and we will advise if you are redecorating. We work on timber door frames, tenement windows and sash and case windows, and the jobs we see most are silicone on a period window that looks wrong and cement or filler used on old window joints that has cracked.
Around Brimpton Common, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
All of our work is guaranteed for twelve months.

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Why deal with it now?
An open joint round the frame lets weather in. Left, water can reach the timber and the wall so renewing it early protects the window. Where a wall is exposed, as many are in small places like Brimpton Common, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and send you a clear quote before we start.

The process
When we arrive, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before we start. The work usually takes a few hours for a single window, longer for several. Somewhere as small as Brimpton Common, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about earlier repairs to the joints

Advice
Work for landlords, hotels and businesses
We work for letting agents and landlords as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.
In hotels, rooms out of use cost money, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
When to call us in Brimpton Common
Rain on the window surround works into any crack and pushes it out. Exposed elevations generally fail first.
Look out for these signs:
- Tired mastic found when preparing windows for paint
- Crumbling sand mastic round a window
- Silicone on a period window that looks wrong
- Cement or filler used on old window joints that has cracked
Managing a site like The Hurst School? Then larger buildings have plenty of frames, and the mastic around each one ages.
What your quote should include
- Whether all the old sealant comes out first
- Whether you can choose the colour
- How much experience the applicator has
- When the joint can take water or movement

What sand mastic looks like in Brimpton Common
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For an older house near a landmark such as Church of St Nicholas, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For landlords with property near Midgham station, any sash windows need sound mastic to keep draughts and rain out.

Aftercare tips
After the cure time, these simple habits help:
- Get any rot dealt with first
- Sort the mastic before the decorators arrive
- Check the mastic when you check the paintwork
- Avoid heavy scraping on the mastic joint
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look before trying a quick fix.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
Your questions about sand mastic in Brimpton Common
I let a flat near Midgham station. Can you help?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.
Do you cover Brimpton Common for sand mastic?
Yes, Brimpton Common is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job, and we’ll send you a clear quote.
Are you insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
How long does sand mastic take?
That depends on the amount of work, but as a guide it takes a few hours for a single window, longer for several. We’ll give you a better idea when we quote.
Is there any odour?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Can sand mastic be painted?
Sand mastic is normally left unpainted, which is what traditional guidance recommends. Ask us before decorating.
Which is right for my windows, sand mastic or modern sealant?
It depends on the window. Period windows in stone or brick normally suit sand mastic and newer frames usually get a flexible sealant.
