How we handle external mastic in Clanfield
Ground-floor and low-level joints are straightforward to reach. Where joints are higher up, tell us about the building when you get in touch and we’ll confirm what’s needed to reach them safely. If you’re dealing with sealant that has lost its bond to the brick or render and weeds or debris growing in open joints, we can put it right, on concrete & block, copings & trims and brickwork movement joints alike.
In a village or hamlet like Clanfield, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
You get a one-year guarantee, the same in Clanfield as everywhere else we work.

Clanfield questions
Do you work for landlords with property near Rowlands Castle station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or email us and tell us about the property, and we’ll send you a clear quote.
Is Clanfield in your area for external mastic?
Yes. Our work covers London and the South East, and Clanfield is part of that. You can phone 0345 464 0079 or send us an email and tell us what needs doing, and we’ll give you a clear price.
Do the sealants smell?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
Does someone need to be in?
Access is agreed with you when the job is booked. Indoors, that usually means someone at home.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply ring 0345 464 0079 or drop us an email.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Can new sealant go over the old?
No, it won’t last. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Walls and rooflines in Clanfield
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.
In the older streets around Church of St James, an extension built onto an older house moves differently, and the joint between them takes the strain. If you look after a building such as Clanfield Junior School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Rented homes near Rowlands Castle station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Walk round the building once a year and look at the joints
- Keep soil, plants and ivy away from the joints
- Check the sealant is paintable before painting near it
- Tell anyone working on the walls about the movement joints
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
A joint that has stopped moving pushes the movement elsewhere, normally as cracking in the brickwork or render nearby. Resealing it early helps prevent that.
For landlords and businesses
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can be quoted together.
Why it’s worth doing now in Clanfield
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. 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.
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 any work starts, so you know where you stand.

Should I try it myself first?
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
