Sand mastic for homes and businesses in Jacobs Well
Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. The old mastic is raked out, and new mastic is applied and shaped by hand. If you are dealing with mastic dropping out of the joint and draughty sash windows at the surround, we can help, on tenement windows, period & listed homes and brick reveals alike.
Around Jacobs Well, 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.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Why deal with it now?
Replacing sash windows is a big decision for a period home and on a listed home, consent may be needed. Where the frames are in good order, new mastic seals the surround. In a small place like Jacobs Well, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

When to call us in Jacobs Well
Rain on the window surround works into any crack and pushes it out. Windows facing the weather tend to go first.
People generally contact us after spotting something like this:
- Patchy fillers round a sash window
- Mastic worn away on windows facing the weather
- Mastic dropping out of the joint
- Silicone on a period window that looks wrong
Schools such as Weyfield Academy are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
Questions to ask before you book
- Whether they’re fully insured
- Which colour the sealant will be
- Is the old sealant removed completely?
- When the joint can take water or movement
Sand mastic in Jacobs Well: local notes
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Guildford Castle (about 2.3 miles south) are a reminder that the area around Jacobs Well has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Homes close to St Peter's Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. Letting a property close to Worplesdon station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about.

Aftercare tips
So the new joints stay in good condition:
- Ask us before painting near the mastic
- Have rotten timber repaired before new mastic goes in
- Sort the mastic before the decorators arrive
- Ask the planning authority about consent for listed or conservation-area homes
Leave the new mastic alone while it firms up. It forms a skin fairly soon but needs longer to fully harden.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
When something else is needed
It helps to know what we can’t do:
- Decayed frames that need repair
- Sash cords, weights and draught-proofing of the sashes
- Damaged stone surrounds
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly before you book.

Common questions in Jacobs Well
Will you come out to Jacobs Well?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Worplesdon station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
When will the new mastic be hard?
It forms a skin fairly soon, then hardens over a longer period. The weather and joint depth both affect it.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us, and we’re fully insured.
Do you remove the old sealant?
Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.
Can I paint the new mastic?
It’s traditionally left unpainted, which is what traditional guidance recommends. Ask us before decorating.
Do I need permission for sand mastic on a listed building?
Check with your local planning authority. They decide whether consent is needed for work to your windows.

Should I try it myself first?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
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.
What we do, step by step
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours per window, depending on the condition of the joints. For a village or hamlet like Jacobs Well, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
