Window mastic for homes and businesses in Alfriston
Behind a thin line of old mastic there’s sometimes a deep void. Filling it with sealant alone leaves a joint that can’t move properly, so deep gaps get backing rod first. That way the new bead bonds to the frame and the wall only. We work on aluminium frames, timber windows & doors and window sills, and common reasons people get in touch are gaps where the sill meets the wall and cold air getting in at the frame edge.
In a village or hamlet like Alfriston, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.

What we are called out for in Alfriston
Every frame moves through the day. 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.
Signs it’s time to call us include:
- Damp patches on the reveal after heavy rain
- A bead that does not match the frame
- Whistling draughts around closed windows
- Untidy mastic left by window fitters
Schools such as Alfriston School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
Before you book anyone

- Who does the work, and how experienced they are
- How long to leave it before use
- Is the old sealant removed completely?
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Paint up to the joint, not over it
- Keep paint and stain on wooden frames in good order
- Use gentle cleaners on frames and sealant
- Make sure the drainage slots are not blocked
Keep the new mastic undisturbed while it cures, for as long as we advise. Do not point a pressure washer at the joints.
Leaks normally show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
Frames and glazing around Alfriston
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Alfriston Clergy House (about 0.2 miles south-east) are a reminder that the area around Alfriston has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Letting a property close to Berwick (Sussex) station? Then renewing tired window mastic between tenants heads off draught and damp complaints. Homes close to Church of St. Andrew include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Leave it or put it right?
Working on frames from a ladder with a sealant gun is not easy, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, using a product chosen for the frame and wall. Around Alfriston, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
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.
Why us?
- 4.9 on Google from 180+ five-star reviews

What sealant work can’t fix
New sealant can’t fix everything, and we will tell you before any work starts. Sealant will not put right:
- Penetrating damp from a failed cavity tray or render
- A failed sealed unit that has misted up
- Soft or decayed wood in the frame
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly before booking.

What the job involves on each surface
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the threshold joint takes a lot of water. We prepare and reseal every joint, backing the deep ones.
Composite doors
Draughts round the door leaf usually come from worn seals or adjustment, not the mastic. We seal the frame and let you know about anything else.
