When something else is needed
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Damp problems in the wall away from the window
- Rotten timber, which needs a joiner first
- A door that needs adjusting, rehanging or new seals

Window mastic for homes and businesses in Rotherfield
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. That way the new bead bonds to the frame and the wall only. Typical jobs include black, perished sealant on frames and cold air getting in at the frame edge, across window sills, patio & French doors and timber windows & doors.
In a village or hamlet like Rotherfield, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
All our work comes with our 12-month guarantee, wherever you are in East Sussex.

Do you need window mastic in Rotherfield?
A lot of older mastic was never designed to stay flexible. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.
Look out for any of the following:
- Black, perished sealant on frames
- Hard, cracked sealant around windows
- Draughty joints inside around the window
- Whistling draughts around closed windows
Rented homes near Crowborough 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.

Aftercare tips
Aftercare is simple:
- Keep drainage slots and sill grooves clear
- Air rooms to keep condensation down around windows
- Check the mastic once a year
- Keep jet washers away from the mastic
Try not to touch the new joint while it cures, following the cure time we give you. Don’t point a pressure washer at the joints.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
What happens on the day
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take anything from an hour or two to a full day, depending on how many frames there are. Somewhere like Rotherfield needs a little journey planning: 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.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- 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.
How to prepare
- Tell us about any water getting in
- Let us know about stairs, lifts or work at height
- Keep pets and children clear of the area while we work

Related advice
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Window mastic in Rotherfield: local notes
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Managing a site like Rotherfield Primary School? Then the mastic around its windows and doors needs looking after like any other building’s. If you live in an older home near The Parish Church of St Denys, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

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 tidy bead in anthracite grey, black or a matching colour keeps the clean look.
uPVC windows
uPVC expands and contracts noticeably with temperature, so the joint needs a low-modulus sealant that stays flexible. White is the usual colour, with brown, anthracite grey and black for coloured frames.
