Sand mastic in Aldham, done properly
A silicone bead around a sash window can look out of place and is not always the right material. Sand mastic is the traditional choice and we can swap the silicone for it. We are often asked to deal with gaps where the frame meets the masonry and gaps round a timber door in stone or brick, across stone surrounds, sash and case windows and period & listed homes.
In a village or hamlet like Aldham, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.

Why act early in Aldham
New mastic over crumbling mastic will not hold. We remove the loose material first so the new mastic stays put. In a small place like Aldham, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Combining jobs into one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

Aldham questions
Can you help a landlord with a rental near Marks Tey station?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear quote.
Do you cover smaller places like Aldham?
Yes. Aldham is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can sand mastic be painted?
Sand mastic is normally left unpainted, as guidance on traditional windows advises. Ask us before decorating.
Where are you based?
We work from Crawley. Our applicators cover Aldham.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Do you offer different sealant colours?
Most of the time, yes. We will tell you which colours the right product comes in and agree one before any work starts.
Can you replace silicone on a period window with sand mastic?
Yes. The silicone is cut out and the joint cleaned before the sand mastic goes in.
How long does sand mastic take?
As a guide, most jobs take anything from a few hours to a full day, depending on how many windows. Larger jobs naturally take longer, and we’ll tell you how long to expect.

Signs you need sand mastic in Aldham
Some old mastic was never deep enough. Mastic that’s too thin cracks and drops out so we make sure the new mastic is the right thickness.
The most common problems we see are:
- Wind and rain getting in round a sash window
- Cracked mastic round a front door frame
- Mastic worn away on windows facing the weather
- A silicone bead on a sash window that spoils the look
For an older house near a landmark such as Church of St Margaret and St Catherine, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
What your quote should include
- What the cure time is
- Is the old sealant removed completely?
- Is VAT in the price?
- Whether they’re fully insured
How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Check with your local planning authority if your home is listed
- Avoid heavy scraping on the mastic joint
- Plan mastic work ahead of painting
- Don’t paint over the new mastic
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look before trying a quick fix.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.
What sand mastic looks like in Aldham
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you look after a building such as Holy Trinity CofE Primary School, larger buildings have plenty of frames, and the mastic around each one ages. Letting a property close to Marks Tey station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.

Should I try it myself first?
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.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
