Window mastic in Woolbridge
Every window and door frame has a gap around it, and mastic is what closes it. When it cracks, hardens or pulls away, draughts and rain get in. Our applicators cut it out and replace it with a flexible, weatherproof sealant. If you have black, perished sealant on frames and mastic that has split away from the wall, we can put it right, whatever the surface.
Outdoor sealant needs dry, clean surfaces, so work on frames around Woolbridge is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
Our work is backed for twelve months, in Woolbridge and everywhere else we cover.

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Common problems we fix in Woolbridge
Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. If the sealant can’t stretch, it splits.
These are the problems we are asked about most:
- Gaps between the frame and the inside reveal
- Untidy mastic left by window fitters
- Whistling draughts around closed windows
- Cracked sealant at the sill ends
Managing a site like Mayfield Church of England Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.
Questions to ask before booking
- Whether all the old sealant comes out first
- Whether you can choose the colour
- How long the guarantee is
- Whether they’re fully insured
How it works
There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The work itself takes most of a day for a typical house, less for a few frames, including the tidy-up. Somewhere like Woolbridge 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.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- Clear items away from the joints we’re working on
- Mention if the joints have been sealed before
- For indoor joints, keep the area dry beforehand if you can

Advice
What window mastic looks like in Woolbridge
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Rented homes near Crowborough station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. In the older streets around Church of St. Dunstan, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Is there any odour?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.

No, because it fails. The old sealant always comes out first.

Yes, regularly. We can plan bigger jobs in stages to suit the site.
Different surfaces, different methods
Composite doors
A composite door usually sits in a plastic outer frame, and the joint around it is sealed like a window. We match the colour to the frame.
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. It comes out, deep gaps get backing rod and the joint is resealed.
Landlord and commercial work in Woolbridge
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
For anyone letting property in or around Woolbridge, several properties can go on one quote. Just tell us the addresses and what each one needs.
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Do not use solvent cleaners on the joint
- Wipe condensation off the frames
- Clear any debris from frame drain holes
- Check the mastic once a year
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and a cold room gets colder. A new joint closes it up.
