Can I do it myself?
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.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
About our window mastic in Shatterling
Every window and door frame has a gap around it, and mastic is what closes it. Once that seal fails, wind and rain find the gap. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We work on composite doors, uPVC windows and timber windows & doors, and people most often call us about draughts coming in around windows and doors and damp patches on the reveal after heavy rain.
Mastic can only go onto a dry, clean joint, so window work in Shatterling is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Do I need to be at home?

Do you have sealant for grey or black windows?
Yes. We can use white, brown, anthracite grey, black or clear.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Is it OK to seal over old sealant?
No. The old sealant always comes out first.
Aftercare tips
Good habits help new joints last longer. Our tips:
- Keep paint and stain on wooden frames in good order
- Keep solvents and bleach off the sealant
- Clear any debris from frame drain holes
- Don’t paint over the silicone
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
Wet, windy weather is when failed mastic shows itself, 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.
How the visit works
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a handful of frames, longer for a whole house. For a village or hamlet like Shatterling, 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.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Let us know about parking restrictions
- Let us know about earlier repairs to the joints

Window mastic in Shatterling: local notes
With historic houses such as Goodnestone Park (about 2.5 miles south) nearby, there’s older building stock in the area around Shatterling as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around St Mary's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Letting a property close to Adisham station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Why act early in Shatterling
Running fresh sealant over the old joint is tempting, but new sealant can’t bond to old, crumbling mastic. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. Where a wall is exposed, as many are in small places like Shatterling, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
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, so you know where you stand.

When to call us in Shatterling
Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, so it comes away long before its time.
It’s worth asking for a quote if you see:
- Whistling draughts around closed windows
- Rain getting in at the frame or under the sill
- Gaps between the frame and the inside reveal
- Cracked or shrunken mastic around the frame
For site and facilities teams at buildings such as Wingham Primary School, its window and door frames need their mastic kept sound, just like a home’s.
