How we handle window mastic in Warninglid
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. The old mastic is removed and the joint resealed with a flexible exterior sealant. If you have gaps left after new windows were fitted and gaps where the sill meets the wall, we can put it right, whatever the surface.
Around Warninglid, 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.
Every job is covered by a one-year guarantee, wherever you are in West Sussex.

Quotes for window mastic in Warninglid
Your quote is based on your job. We look at:
- Any mould that needs treating
- The size of the job
- Access and height
- The type of sealant required
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
What we need to know
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- The type of property
- Where the property is
- Whether it has been sealed before
- Photos by email, if that is easy
If you’re in Warninglid and need window mastic, phone 0345 464 0079 or send us an email. Tell us what the problem is and where, and you will get a clear quote before work begins.
Looking after it afterwards
A little care helps the new joints last. Our advice:
- Don’t aim a pressure washer at the joints
- Paint up to the joint, not over it
- Air rooms to keep condensation down around windows
- Clean frames with a soft cloth and soapy water
On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
What we do, step by step
Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and clear up. It usually takes most of a day for a typical house, less for a few frames. Somewhere like Warninglid needs a little journey planning: 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.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
Getting ready for the visit
- Tell us about any water getting in
- Plan for the work area to be out of bounds to pets and children
- Mention if the joints have been sealed before

Windows and doors in Warninglid
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Tyes Place (about 1.8 miles north-east) are a reminder that the area around Warninglid has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
For landlords with property near Balcombe station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Can I do it myself?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Your questions about window mastic in Warninglid
Will you come out to Warninglid?
Yes. Warninglid is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

Yes, Warninglid is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or send us an email and tell us what needs doing, and we’ll give you a clear quote.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
I rent my home. Can I book you?
Yes. Check with your landlord; we can send the quote to them too.
Do you work for landlords and businesses?
Yes, we do. We work in homes, commercial premises and hotels, and we’re fully insured.
Can I do it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Is there any odour?
Possibly a little. It fades as the sealant cures.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint.
When it isn’t the sealant
We’ll always be straight with you, so here’s what sealant cannot fix:
- A sash or casement that won’t close properly
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Penetrating damp from a failed cavity tray or render
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly before booking.

Do you need window mastic in Warninglid?
Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, and it lets go sooner than it should.
Keep an eye out for these signs:
- Gaps where the sill meets the wall
- Gaps between the frame and the inside reveal
- Water coming in at the bottom corners of a door
- Sealant in the wrong colour for the frame
Historic houses such as Tyes Place, about 1.8 miles north-east, show how far back building around Warninglid goes.
