About our window mastic in Burlings
If you can feel air around a shut window, the gap is often at the frame. A new joint stops the air getting through. If the draught is through the window seals instead, we’ll tell you. Common call-outs are for draughty joints inside around the window and mastic that has split away from the wall, across patio & French doors, timber windows & doors and composite doors.
In a village or hamlet like Burlings, 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.
We stand behind the work with a 12-month guarantee.

What we do, step by step
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes a morning for a couple of windows and a door. Somewhere as small as Burlings, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- 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
- Let us know about stairs, lifts or work at height
- Try not to wet indoor joints just before the visit
- Mention if the joints have been sealed before

How to look after the new joints
After the cure time, these simple habits help:
- Wash the frames with mild soapy water
- Avoid harsh chemicals near the mastic
- Keep paint off silicone joints
- Check the mastic once a year
Check the drainage slots in the frames aren’t blocked, so rain drains out rather than building up at the sealant.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.
Frames and glazing around Burlings
Historic houses like Down House (about 2.2 miles north-west) are a reminder that the area around Burlings 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. 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.
Homes close to St Katharine's Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you let a flat or house near Knockholt station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

DIY sealant or a professional job?
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 fails, we can still redo it.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Why act early in Burlings
A quick bead over the top of old mastic looks like an easy fix, but it will not grip old, dirty sealant. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. Around Burlings, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not guesswork. That is why we ask a few questions first.

Common problems we fix in Burlings
Joints that are too thin or too deep fail early. A skim of sealant over a wide gap soon tears, and a gap filled solid cannot flex. That is what backing rod is for.
Any of these means the joints need attention:
- Cracked or shrunken mastic around the frame
- Cracked internal joints between frame and plaster
- Rain getting in at the frame or under the sill
- Black, perished sealant on frames
For site and facilities teams at buildings such as Charles Darwin School, the mastic around its windows and doors needs looking after like any other building’s.
What your quote should include
- Which colour the sealant will be
- What product goes in the joint

Different surfaces, different methods
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. The threshold and the bottom corners take the most water, so they get particular care.
Window sills
Masonry sills can have joints where water gets in, including the one between the sill and the frame above. Those are sealed with a product suited to stone or concrete.
Honest limits
We will always be straight with you, so here’s what sealant cannot fix:
- A failed sealed unit that has misted up
- A door that needs adjusting, rehanging or new seals
- Faulty window hardware
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly before you book.
