About our window mastic in Rotherbridge
A window frame and the wall around it expand and shrink at different rates. Heat and cold make frames grow and shrink against brick or render that hardly moves. So the sealant has to stretch and recover, which is why we use a low-modulus product. We work on timber windows & doors, composite doors and aluminium frames, and common reasons people get in touch are damp patches on the reveal after heavy rain and whistling draughts around closed windows.
Mastic can only go onto a dry, clean joint, so window work in Rotherbridge is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
A one-year guarantee comes with the work, just as it does everywhere we cover.

What happens if it’s left?
Failed mastic is not a reason to replace sound windows. Where the frames are sound, new mastic generally deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we will say so. Around Rotherbridge, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on how much there is to do, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts.

What affects the quote in Rotherbridge
We don’t publish a price list, because jobs vary so much. The quote depends on:
- Mould in or behind the old joints
- The number of rooms or windows
- When we can work, for business premises
- Whether the work is at height
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
Helping us quote
Photos by email are helpful but not essential. Try to tell us:
- Any previous sealing or DIY work
- What the problem is, such as mould, gaps, leaks or cracking
- Roughly how big the job is
- Any access issues, like height or stairs
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.

What else we do in Rotherbridge
Rotherbridge: your questions answered
Is Rotherbridge in your area for window mastic?
Yes. We work across London and the South East, and Rotherbridge is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing.
I let a flat near Pulborough station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just ring 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear quote.
Can new sealant go over the old?
No, it will not last. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us, and we’re fully insured.
Where do you work from?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Can new window sealant be painted?
That depends on the product. Silicone is not paintable, but some hybrid sealants are. Mention any painting plans before any work starts.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures.
Are you fully insured?
Yes. We are fully insured.
What we’re called out for in Rotherbridge
Some failures date back to when the windows were fitted. Sealant run over dust, wet brick or loose mortar didn’t grip properly, so it comes away long before its time.
Common reasons people contact us are:
- Hard, cracked sealant around windows
- Cracked internal joints between frame and plaster
- Rain getting in at the frame or under the sill
- A bead that does not match the frame
For site and facilities teams at buildings such as Petworth Cof E Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
What your quote should include
- Whether they’re fully insured
- How the surfaces are prepared before sealing
- The length of the guarantee
- Which sealant they’ll use, and why
What happens on the day
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes most of a day for a typical house, less for a few frames. For a village or hamlet like Rotherbridge, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- 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.
How to prepare
- Let us know if you’ve seen damp or leaks
- Let us know about earlier repairs to the joints
- Clear the area around the work

Window mastic in Rotherbridge: local notes
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Petworth House (about 1.2 miles north-east) are a reminder that the area around Rotherbridge 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 an older house near a landmark such as The Parish Church of All Hallows, the joint between an old wall and a newer frame is usually the first place rain gets in. If you let a flat or house near Pulborough station, renewing tired window mastic between tenants heads off draught and damp complaints.

How the job changes by surface
Window sills
Where a sill meets brick or render, the ends often crack first. We reseal them so rain cannot run into the wall.
Patio & French doors
Water at the foot of a door frame is not always the mastic: blocked drain slots, worn brush seals and threshold details can let water in too. We check before we reseal.
