Window mastic in Chilham
Most frames have an outside joint and an inside one. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. We’re often asked to deal with gaps between the frame and the inside reveal and black, perished sealant on frames, on timber windows & doors, aluminium frames and window sills.
Outdoor sealant needs dry, clean surfaces, so work on frames around Chilham is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
All our work is covered by a one-year guarantee, wherever you are in Kent.

Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
For landlords and businesses
If you manage several properties in or around Chilham, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.
What we can’t put right
Some problems need a builder, plumber or other trade rather than us:
- Worn gaskets, brush seals or a door that has dropped
- Penetrating damp from a failed cavity tray or render
- Condensation trapped between the panes
If you are not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer.

FAQs for Chilham
I let a flat near Chilham station. Can you help?
Yes. We work for landlords and agents as well as homeowners. You can phone 0345 464 0079 or email us with the details for a clear quote.
Do you cover Chilham for window mastic?
Yes. We work across London and the South East, and Chilham is part of that. You can phone 0345 464 0079 or send us an email and let us know what needs doing, and we’ll send you a clear quote.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can new window sealant be painted?
Not if it’s silicone. Tell us your decorating plans and we’ll pick a sealant to suit.
Is it messy?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
Can resealing stop a draught around my window?
Yes, if the air is getting in around the frame. If it’s through the window’s own seals or a hinge, that’s a different fix, and we will say so.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Window mastic in Chilham: local notes
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.
Rented homes near Chilham station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. If you live in an older home near Church of St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

How the job changes by surface
uPVC windows
uPVC expands and contracts noticeably with temperature, so we use a flexible, low-modulus sealant. We match white, brown, anthracite grey and black frames.
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We will tell you which suits your home.
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Keep solvents and bleach off the sealant
- Do not aim a pressure washer at the joints
- Clear any debris from frame drain holes
- Wash the frames with mild soapy water
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just ring 0345 464 0079 or send us an email.
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.
