DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
How we handle sand mastic in Alfold Bars
A silicone bead around a sash window can look out of place and doesn’t suit the building. Sand mastic gives a finish that matches the age of the house, and we can replace one with the other. If you are dealing with gaps between timber frames and stone or brick and silicone on a period window that looks wrong, we can help.
Around Alfold Bars, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

Common questions in Alfold Bars
Do you cover smaller places like Alfold Bars?
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.
What guarantee comes with sand mastic in Alfold Bars?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
What information do you need?
Let us know what needs doing and where. We’ll ask anything else we need to know.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Which is right for my windows, sand mastic or modern sealant?
For period timber windows in stone or brick, sand mastic is often the better fit. Modern frames normally suit a flexible sealant.
Can I add another job to the visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Are you ARBOMaster approved?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Are you fully insured?
Yes. We are fully insured.
When it is not the sealant
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Decayed frames that need repair
- Whether work needs listed building consent
- Broken panes
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly.

Looking after it afterwards
After the cure time, these simple habits help:
- Have rotten timber repaired before new mastic goes in
- Avoid heavy scraping on the mastic joint
- Look over the window mastic once a year
- Ask the planning authority about consent for listed or conservation-area homes
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
Sound mastic protects the frame. Once it fails, water can sit against the timber and timber that stays wet can rot.

Do you need sand mastic in Alfold Bars?
Sand mastic slowly weathers. It hardens, cracks and starts to come away on the stone or timber.
Most people get in touch after spotting something like this:
- Mastic round period door frames that has failed
- Silicone on a period window that looks wrong
- Failed mastic on an exposed elevation
- Open joints round the window box
If you live in an older home near Church of St Nicholas, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What we do, step by step
We bring everything the job needs with us, so you do not need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes a few hours for a single window, longer for several. Somewhere as small as Alfold Bars, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.

How we quote for sand mastic
There’s no set price list, because jobs vary so much. The quote depends on:
- Whether old sealant or filler has to be cut out
- Which sealant suits the joint
- When we can work, for business premises
- The number and length of the joints
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
