Window Mastic in Folkington
Problem with your window and door frames in Folkington? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Rushed sealant from a window installation
- Cracked sealant at the sill ends
- Cracked or shrunken mastic around the frame
Different surfaces, different methods
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. We will point out any rot we find, as that’s a job for a joiner.
uPVC windows
uPVC expands and contracts noticeably with temperature, so we use a flexible, low-modulus sealant. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Window mastic for homes and businesses in Folkington
Whether it’s one leaking patio door or every frame on the house, the work is priced before anything is done. Just call 0345 464 0079 or drop us an email and tell us how many frames there are and how they’re reached. Common call-outs are for old mastic that has gone black or come away and cold air getting in at the frame edge, across timber windows & doors, uPVC windows and patio & French doors.
Somewhere as small as Folkington, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
We stand behind the work with a one-year guarantee, so you are covered after we have gone.

Folkington homes and the weather
Historic houses like Alfriston Clergy House (about 2.5 miles west) are a reminder that the area around Folkington has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Letting a property close to Polegate station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Managing a site like Willingdon Community School? Then the mastic around its windows and doors needs looking after like any other building’s.

Landlords, agents and businesses in Folkington

We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Walk round the house once a year and look at the joints
- Avoid harsh chemicals near the mastic
- Repaint timber before it’s bare
- Don’t aim a pressure washer at the joints
Silicone cannot normally be painted, so if you are planning to paint the frames or walls, tell us beforehand. There are paintable sealants for joints that need it.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. A new joint closes it up.
What we are called out for in Folkington
Frames are never completely still. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. If the sealant can’t stretch, it splits.
The problems people generally mention when they call are:
- Draughty joints inside around the window
- Hard, cracked sealant around windows
- Mastic that’s falling out in pieces
- Leaking joints at the ends of sills
Homes close to The Parish Church of Saint Peter include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What affects the quote in Folkington
Every job gets its own quote. This is what makes a difference:
- Mould in or behind the old joints
- The number of rooms or windows
- How easy the joints are to reach
- Which sealant suits the joint
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Asking for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- If someone has resealed it before
- Any access issues, like height or stairs
- A few pictures by email, if you can
- The problem you’ve noticed
For window mastic in Folkington, ring 0345 464 0079 or send us an email. Tell us what the problem is and where, and you will get a clear quote before we start.
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Folkington: your questions answered
Can you do window mastic in Folkington?
Yes, Folkington is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or email us with a few details of the job.
Do you work for landlords with property near Polegate station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Is it OK to seal over old sealant?
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.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Where is Mr Mastic based?
We’re based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
How long before the joint can be used?
It depends on the product and the temperature. We tell you how long to leave it before we go.
