Window & door mastic in Painters Ash, Kent

How it works
You do not need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours for a handful of frames, longer for a whole house in most cases. In a smaller place like Painters Ash, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We start by checking each window and door with you.
- The old mastic is cut out and the surfaces cleaned back.
- Deep gaps are filled with backing rod to set the depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Finally we tidy up and check each joint.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Mention if the joints have been sealed before
- Let us know about parking restrictions

Advice
Window mastic in Painters Ash, done properly
Some gaps around frames are far deeper than they look. Packing it solid with sealant gives a joint that can’t flex, so deep gaps get backing rod first. The sealant then grips the two sides it should. If you have black, perished sealant on frames and draughts coming in around windows and doors, we can put it right.
Houses in smaller places like Painters Ash can stand more in the open than those in a built-up town, so exposed windows and doors face the weather head on. The mastic around frames on those walls tends to age faster.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Wash the frames with mild soapy water
- Avoid blasting the frames with a pressure washer
- Check the mastic once a year
- Make sure the drainage slots are not blocked
Timber frames need their paint kept up, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
When something else is needed
Before booking, it’s worth knowing the limits:
- A sash or casement that won’t close properly
- Penetrating damp from a failed cavity tray or render
- Misting between the panes of a double-glazed unit (that needs a new unit)
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think before you book.
What we seal

Window mastic in Painters Ash: local notes
Painters Ash is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Historic houses like Cobham College (about 3.6 miles south-east) are a reminder that the area around Painters Ash 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.
If you look after a building such as Painters Ash Primary School, the mastic around its windows and doors needs looking after like any other building’s. If you live in an older home near Church of All Saints, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Painters Ash questions
Do you work for landlords with property near Ebbsfleet International station?
Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.
Does living near the coast affect window mastic in Painters Ash?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are generally the first to need attention.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Do you have sealant for grey or black windows?
Generally, yes. Mention the frame colour when you ask for a quote and we’ll use the nearest match.
Will new mastic stop draughts?
It will if the frame joint is the problem. We check where the draught is before work begins.
Do you guarantee window mastic?
Yes, for 12 months. A yearly look at the joints helps them last.
Which products do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.

Why it’s worth doing now in Painters Ash
Working on frames from a ladder with a sealant gun isn’t easy, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. In a smaller place like Painters Ash, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first.

- Neat joints and a tidy finish
- 180+ five-star Google reviews

Signs you need window mastic in Painters Ash
Older frames were often sealed with products that set hard. Once it’s rigid, every bit of frame movement pulls at it, and a gap opens along one edge.
If you can see any of these, it’s time to have the joints looked at:
- Cracked or shrunken mastic around the frame
- Untidy mastic left by window fitters
- A bead that doesn’t match the frame
- Old mastic that has gone black or come away
Rented homes near Ebbsfleet International 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.
