About our window mastic in Shirkoak
Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. We work on window sills, aluminium frames and uPVC windows, and people most often call us about whistling draughts around closed windows and cracked internal joints between frame and plaster.
Around Shirkoak, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

For landlords and businesses
Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll quote.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
Can I do it myself?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What sealant work can’t fix
We’d rather tell you now than do work that will not last, so these are the limits:
- Soft or decayed wood in the frame
- Worn gaskets, brush seals or a door that has dropped
- A failed sealed unit that has misted up
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think before booking.

Do you need window mastic in Shirkoak?
Some failures date back to when the windows were fitted. Sealant run over dust, wet brick or loose mortar never bonded as it should, and it lets go sooner than it should.
Common reasons people contact us are:
- Black, perished sealant on frames
- Leaking joints at the ends of sills
- Hard, cracked sealant around windows
- White mastic on grey or black frames
If you let a flat or house near Ham Street station, renewing tired window mastic between tenants heads off draught and damp complaints.

How the visit works
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a morning for a couple of windows and a door. For a village or hamlet like Shirkoak, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, 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.
- We tool the joint so water runs off, then clear up.
Before we arrive
- Clear the area around the work
- Let us know about parking restrictions
- Let us know if you’ve seen damp or leaks

Common questions in Shirkoak
Is Shirkoak within the area you cover?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you do window mastic in Shirkoak?
Yes, Shirkoak is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or email us with a few details of the job, and we’ll send you a clear quote.
Where do you work from?
We work from Crawley. We cover Shirkoak and the rest of Kent, along with the rest of our area.
Do you remove the old sealant?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you do not need to watch us work.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can I add another job to the visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
What window mastic looks like in Shirkoak
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Smallhythe Place (about 4.8 miles south-west) nearby, there’s older building stock in the area around Shirkoak 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.
If you live in an older home near Parish Church of All Saints, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For site and facilities teams at buildings such as Woodchurch Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
Shirkoak is about 5 miles south-west of Ashford, in Kent. Homes, rented property, offices and hotels in Shirkoak can book us for window mastic, old or new, large or small. The work is guaranteed for a year. Our Kent coverage runs to 922 places, and Shirkoak is one of them. We also work in Crawley, about 42 miles from Shirkoak.

Around Shirkoak
We work in homes and buildings around Stone Wood and The Bonny Cravat Inn and the streets around them. The nearest railway station is Ham Street station, roughly 4 miles south-east. Other landmarks nearby include Romden Castle (4.6 miles north-west) and Woodchurch Village Life Museum (0.7 miles south). Not far away are Orlestone Forest.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Air rooms to keep condensation down around windows
- Wash the frames with mild soapy water
- Keep jet washers away from the mastic
- Keep drainage slots and sill grooves clear
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.
What the job involves on each surface
Window sills
Masonry sills can have joints where water gets in, and the joint under the frame can let rain run behind. We seal those with a sealant suited to masonry.
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. Most leaks start at the bottom corners, so we pay close attention there.
