Window mastic in Clanfield
Every window and door frame has a gap around it, and mastic is what closes it. Once that seal fails, wind and rain find the gap. Our applicators cut it out and replace it with a flexible, weatherproof sealant. Typical jobs include sealant in the wrong colour for the frame and mastic that has split away from the wall, on patio & French doors, window sills and aluminium frames.
In a village or hamlet like Clanfield, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Different surfaces, different methods
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. It comes out, deep gaps get backing rod and the joint is resealed.
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so the joint must stay flexible. We seal onto sound, dry paintwork or timber.
Frames and glazing around Clanfield
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.
Rented homes near Rowlands Castle station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. For an older house near a landmark such as Church of St James, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Managing a site like Clanfield Junior School? Then the mastic around its windows and doors needs looking after like any other building’s.

What else we do in Clanfield
The process
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take a few hours for a handful of frames, longer for a whole house. For a village or hamlet like Clanfield, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Preparing for the visit
- Clear the area around the work
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any water getting in

How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Look round the frames every year or so
- Do not use solvent cleaners on the joint
- Clear any debris from frame drain holes
- Keep paint and stain on wooden frames in good order
A yearly look round the frames is enough. Small splits are simple to catch before they leak, and if anything looks wrong, just call 0345 464 0079 or send us an email.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and a cold room gets colder. A new joint closes it up.

Yes. Clanfield is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can new window sealant be painted?
That depends on the product. Some hybrid sealants can be painted; silicone cannot. Mention any painting plans before we start.
Can new sealant go over the old?
No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.

Yes, in most cases. Access is planned before we start.
Why it’s worth doing now in Clanfield
Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. Older cottages and farmhouses around Clanfield can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
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.

When it isn’t the sealant
Sealant isn’t the answer to every problem, and we’d rather say so up front. It won’t solve:
- Draughts through the window seals rather than the frame
- Damp coming through the wall itself rather than the frame joint
- Condensation trapped between the panes
If you’re not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer before booking.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
