Window mastic in Swanton
The mastic around a window or door seals the gap between the frame and the wall. When it cracks, hardens or pulls away, draughts and rain get in. The old mastic is removed and the joint resealed with a flexible exterior sealant. If you have cold air getting in at the frame edge and mastic that’s falling out in pieces, we can put it right, on patio & French doors, aluminium frames and uPVC windows alike.
Around Swanton, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
A 12-month guarantee comes as standard, so you’re covered after we’ve gone.

How the visit works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from an hour or two to a full day, depending on how many frames there are, and the area is left clean. For a village or hamlet like Swanton, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Move anything stored near the joints
- Mention any sign-in or site rules at work premises

What affects the cost of window mastic
For a quick quote, just ask. The main things that affect it are:
- How many areas need sealing
- Any mould that needs treating
- Access and height
- Which sealant suits the joint
What it costs depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts.
What we need to know
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- What the problem is, such as mould, gaps, leaks or cracking
- Whether it’s a home or a business
- How many joints, rooms or windows are involved
- How we’d reach the joints
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we will talk you through the work.
Leave it or put it right?
The work is quick compared with the damage it prevents: it takes a few hours for a handful of frames, longer for a whole house. Leave it until water is coming in and you may need plastering and decorating as well. Where a wall is exposed, as many are in small places like Swanton, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Ask us for a quote and we’ll explain what it covers.

- Colour picked to suit the job

When to call us in Swanton
Water runs down the glass onto the sill, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
The most common problems we see are:
- Draughts coming in around windows and doors
- Sealant in the wrong colour for the frame
- Mastic that has split away from the wall
- Cracked internal joints between frame and plaster
For an older house near a landmark such as Church of St Dunstan, the joint between an old wall and a newer frame is normally the first place rain gets in.
Before you book anyone
- Which colour the sealant will be
- What happens if they find a problem under the old sealant
- What product goes in the joint
- What guarantee comes with the work
When it is not the sealant
To be straight with you, there are a few things sealant will not fix:
- Damp coming through the wall itself rather than the frame joint
- Worn gaskets, brush seals or a door that has dropped
- Faulty window hardware
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think.

Aftercare tips
To keep the joints looking good and working properly:
- Keep jet washers away from the mastic
- Repaint timber before it’s bare
- Use gentle cleaners on frames and sealant
- Do not use solvent cleaners on the joint
Check the drainage slots in the frames aren’t blocked, so water can run away instead of sitting against the joint.
Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. Any of these is worth a call.
Surface by surface
Composite doors
Draughts round the door leaf normally come from worn seals or adjustment, not the mastic. We will tell you if that is what we find.
uPVC windows
We clean the frame edge carefully so the plastic isn’t marked, then the new bead is laid against the frame and the wall.
Window mastic in Swanton: local notes
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Old Soar Manor (about 1.5 miles west) nearby, there’s older building stock in the area around Swanton as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Managing a site like Mereworth Community Primary School? Then its window and door frames need their mastic kept sound, just like a home’s. Letting a property close to Wateringbury station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
