Why act early in Charlwood
Draughts and leaks do not always mean new windows. Where the frames are sound, new mastic usually deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we’ll say so. Around Charlwood, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.

About our window mastic in Charlwood
If you can feel air around a shut window, the gap is often at the frame. A new joint stops the air getting through and quietens the whistle on windy days. Where the air is getting in through the window itself, we’ll say so. If you’re dealing with gaps where the sill meets the wall and mastic that’s falling out in pieces, we can put it right.
Homes in small places like Charlwood often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

What the job involves on each surface
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A neat, narrow bead in a colour to match suits the frame.
Window sills
Masonry sills can have joints where water gets in, and the joint under the frame can let rain run behind. Those are sealed with a product suited to stone or concrete.
Honest limits
In fairness, there are a few things sealant will not fix:
- A door that needs adjusting, rehanging or new seals
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Damp coming through the wall itself rather than the frame joint
If you are not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer.

What we do, step by step
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and clear up. Most jobs take a few hours for a handful of frames, longer for a whole house. For a village or hamlet like Charlwood, 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.
- 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.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Getting ready for the visit
- Clear the area around the work
- Tell us about any previous sealing or DIY attempts
- Keep pets and children clear of the area while we work

FAQs for Charlwood
I let a flat near Ifield station. Can you help?
Yes, we work for landlords and agents. Just call 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear quote.
Is Charlwood within the area you cover?
Yes, Charlwood is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Will the old sealant be removed?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Are you insured?
Yes. We’re fully insured.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all.
How do I get a quote for window mastic in Charlwood?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Does the work come with a guarantee?
Yes. All our work carries a 12-month guarantee, and we are fully insured.
Can I do it myself?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Signs you need window mastic in Charlwood
Frames are never completely still. Sun on a frame makes it expand, and it contracts again overnight, while the brick or render around it hardly moves. A sealant that can’t keep up eventually tears.
Most people get in touch when they notice one of these:
- Gaps left after new windows were fitted
- Black, perished sealant on frames
- Gaps between the frame and the inside reveal
- Draughts coming in around windows and doors
If you look after a building such as Charlwood Village Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
What your quote should include
- Which sealant they’ll use, and why
- How much experience the applicator has
- The length of the guarantee
- Whether they seal over old material or remove it
Windows and doors in Charlwood
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.
If you live in an older home near Church of St Nicholas, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you let a flat or house near Ifield station, renewing tired window mastic between tenants heads off draught and damp complaints.
