Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Avoid patching sand mastic with silicone
- Plan mastic work ahead of painting
- Ask a joiner to look at soft timber first
- Clear gutters so water does not pour onto the windows
Do not run silicone over the new mastic. If you see a crack, ask us to take a look before trying a quick fix.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
Sand mastic for homes and businesses in Warborough
Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. Out comes the old, loose mastic, and new mastic is applied and shaped by hand. Typical jobs include open joints round the window box and mastic that needs renewing before redecorating, across tenement windows, sash and case windows and brick reveals.
Around Warborough, 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.
Every job comes with a one-year guarantee.

Questions from Warborough
Is Warborough in your area for sand mastic?
Yes, Warborough is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll send you a clear quote.
Do you work for landlords with property near Culham station?
Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.
Do you work for hotels and businesses?
Yes. We’ve worked for hotels, offices and other businesses, and we’re fully insured.
Is consent needed for window work on a listed home?
Yes, it’s worth checking. Your local planning authority can say if consent is needed for work on a listed home or in a conservation area.
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. We remove it all first.
Are you fully insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
What sealant work cannot fix
It helps to know what we cannot do:
- Broken panes
- Planning or listed building consent (your local planning authority decides)
- Sashes that rattle, stick or won’t open
If you’re not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer.

What sand mastic looks like in Warborough
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Brightwell Manor (about 2.2 miles south-west) nearby, there’s older building stock in the area around Warborough as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Rented homes near Culham station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about. If you live in an older home near Church of St Lawrence, frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you look after a building such as St Laurence Church of England (A) School, its window and door frames need their mastic kept sound, just like a home’s.

Can I do it myself?

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

Advice
Why act early in Warborough
Draughts round a sash window are not always the sashes. Gaps between the frame and the wall can be just as bad and new mastic seals them. Around Warborough, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on the amount of work, how hard the old material is to remove and access to the work. We give a clear quote before work begins, so you know where you stand.
