How we handle sand mastic in Micheldever Station
Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. We rake it out and renew it so the surround looks right again. If you’re dealing with cement or filler used on old window joints that has cracked and gaps round a timber door in stone or brick, we can help.
Mastic can only go onto a dry, clean joint, so window work in Micheldever Station is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Our work is backed for twelve months.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed 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.
Sand mastic in Micheldever Station: local notes

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Have rotten timber repaired before new mastic goes in
- Make sure water runs off the sill
- Check the mastic when you check the paintwork
- Sort the mastic before the decorators arrive
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look before trying a quick fix.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.
For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
What happens on the day
When we arrive, we look over the joints with you first. We protect the surfaces around the joints before work begins. Most jobs take anything from a few hours to a full day, depending on how many windows. In a small place like Micheldever Station, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each surround is checked first.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic isn’t too thick.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Move anything stored near the joints
- Plan for the work area to be out of bounds to pets and children

Related advice
Leave it or put it right?
New mastic over crumbling mastic won’t hold. We remove the loose material first so the new mastic stays put. In a small place like Micheldever Station, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
The cost depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before we start, so you know where you stand.
Why us?
- Every job guaranteed for a year
- Anti-fungal sanitary silicone in wet areas
- Neat joints and a tidy finish
- We never seal over old sealant
Micheldever Station questions
Can you help a landlord with a rental near Overton station?
Yes. We work for landlords and agents as well as homeowners, and several properties can be quoted together. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Is Micheldever Station within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Is it possible to paint over sand mastic?
It’s traditionally left unpainted, as guidance on traditional windows advises. Talk to us before any painting near it.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Can you replace silicone on a period window with sand mastic?
Yes, it’s a common request. All the old silicone is removed first so the mastic beds in well.
Is there any odour?
Sometimes, a little. It fades as the sealant cures.
What affects the cost of sand mastic
Jobs vary more than people expect. What affects the quote:
- Whether old sealant or filler has to be cut out
- Whether the work is at height
- The number and length of the joints
- When we can work, for business premises
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
