Sand mastic in Woolmer
Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. If you’re dealing with draughty sash windows at the surround and mastic round period door frames that has failed, we can help, on stone surrounds, sash and case windows and brick reveals alike.
Around Woolmer, 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.
You are covered for a year from the day we finish. If anything is not right with it, call 0345 464 0079 or drop us an email.

Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Sort the mastic before the decorators arrive
- Check with your local planning authority if your home is listed
- Keep sills and gutters clear so water drains away
- Ask a joiner to look at soft timber first
Leave the new mastic unpainted, which is the traditional advice. Ask us before any decorating around it.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.
Woolmer questions
Can you help a landlord with a rental near Liss station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Will you come out to Woolmer?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can I paint the new mastic?
It’s traditionally left unpainted, as guidance on traditional windows advises. Talk to us before any painting near it.
Can I choose the sealant colour?
Most of the time, yes. We’ll tell you which colours the right product comes in.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Is the work guaranteed?
All our work has a 12-month guarantee.
Can you do several jobs on one visit?
Yes. Several rooms, windows or areas can go on one quote.
Woolmer homes and the weather
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near St Matthew's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Managing a site like St Matthew's Church of England Aided Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.

Why it’s worth doing now in Woolmer
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic suits the building and finishes neatly against the masonry. Where a wall is exposed, as many are in small places like Woolmer, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

The process
Before we leave, we go over the finished joints with you. The work normally takes a few hours per window, depending on the condition of the joints, depending on how much there is to do. In a small place like Woolmer, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic isn’t too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.
Before we arrive
- Mention if the joints have been sealed before
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any parking rules near the property
