About our sand mastic in Bell's Corner
Across Bell's Corner, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand, finished to suit the masonry. We work on stone surrounds, sash and case windows and timber door frames, and people most often call us about tired mastic found when preparing windows for paint and failed mastic on an exposed elevation.
Around Bell's Corner, 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 covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

Why deal with it now?
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic is the traditional material and finishes neatly against the masonry. In a small place like Bell's Corner, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs. Ask us for a quote and we’ll explain what it covers.

What else we do in Bell's Corner
When it isn’t the sealant
New sealant can’t fix everything, and we’d rather say so up front. It will not solve:
- Sash cords, weights and draught-proofing of the sashes
- Putty and glazing repairs
- Whether work needs listed building consent
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly.

What the job involves on each surface
Brick reveals
Loose mastic comes out and deep gaps are packed before pointing.
Period and listed homes
On a listed home or in a conservation area, the right material matters. Like-for-like sand mastic is generally favoured.
Landlords, agents and businesses in Bell's Corner
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
How to look after the new joints
Aftercare is simple:
- Find out about consent before window work on a listed home
- Clear gutters so water does not pour onto the windows
- Take care around the mastic when scraping paint
- Do not run silicone over sand mastic
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.
The process
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and clear up. It usually takes anything from a few hours to a full day, depending on how many windows. In a small place like Bell's Corner, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Before we arrive
- Mention any parking rules near the property
- For indoor joints, keep the area dry beforehand if you can
- Mention any sign-in or site rules at work premises

Is sand mastic in Bell's Corner guaranteed?
All our work, in Bell's Corner and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Do you remove the old sealant?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.

Can old silicone round a sash window be swapped for sand mastic?
In most cases. We remove the silicone and clean the joint, then point it with sand mastic.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
I’m a tenant. Can you help?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
What affects the cost of sand mastic
Every job gets its own quote. This is what makes a difference:
- How many areas need sealing
- The product the joint needs
- How much old sealant there is and how hard it is to remove
- The number and length of the joints
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

- A few pictures by email, if you can

Bell's Corner homes and the weather
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to Church of St Mary include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you look after a building such as Stoke-by-Nayland Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
