The process
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to a full day, depending on how many windows. Somewhere as small as Catsfield, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each surround is checked first.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic isn’t too thick.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Where the joints are inside, avoid wetting them before we arrive
- Clear items away from the joints we’re working on

Can I do it myself?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
What we cannot put right
Before you book, it’s worth knowing the limits too:
- Broken panes
- Decayed frames that need repair
- Crumbling stone or brickwork round the window

Sand mastic in Catsfield: local notes
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. Historic houses like Durhamford Manor (about 4.4 miles north-east) are a reminder that the area around Catsfield has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
If you look after a building such as Catsfield Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages. Rented homes near Battle station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about. For an older house near a landmark such as The Parish Church of St Laurence, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Do you offer different sealant colours?
In most cases you can choose. We will explain which colours are available.
Can I paint the new mastic?
Sand mastic is normally left unpainted, which is what traditional guidance recommends. Talk to us before any painting near it.
Do I need permission for sand mastic on a listed building?
Your local planning authority is the one to ask. They decide whether consent is needed for work to your windows.
Should I use sand mastic or silicone?
We’ll talk it through with you. Period homes often look best with sand mastic, and modern sealants suit newer frames.
How long does the job take?
Most jobs take a few hours for a single window, longer for several. We’ll confirm how long 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
To keep the joints looking good and working properly:
- Check the mastic when you check the paintwork
- Take care around the mastic when scraping paint
- Check with your local planning authority if your home is listed
- Have rotten timber repaired before new mastic goes in
Leave the new mastic alone while it firms up. It skins over quickly, but takes longer to harden fully.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
Why deal with it now?
An open joint round the frame lets weather in. Left, water can reach the timber and the wall, so dealing with it now protects both. Older cottages and farmhouses around Catsfield can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and agree the price before starting.
