How we handle window mastic in Wivelsfield Green
Most frames have an outside joint and an inside one. Outside, the mastic keeps rain out; the internal joint closes the gap to the plaster and stops draughts. Either or both can be done. We work on composite doors, patio & French doors and uPVC windows, and the jobs we see most are cracked internal joints between frame and plaster and untidy mastic left by window fitters.
Mastic can only go onto a dry, clean joint, so window work in Wivelsfield Green is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Big or small, you get the same 12-month guarantee in Wivelsfield Green and across West Sussex.

Windows and doors in Wivelsfield Green
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Ockenden Manor (about 4.3 miles north-west) are a reminder that the area around Wivelsfield Green 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 is traditional sand mastic.
Letting a property close to Wivelsfield station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. For an older house near a landmark such as Ote Hall Chapel, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Do you need window mastic in Wivelsfield Green?
Mastic ages in the weather. UV light hardens the outside of the bead, and over the years it loses its give, cracks and comes away.
If you can see any of these, it’s time to have the joints looked at:
- Mastic that’s falling out in pieces
- Cold air getting in at the frame edge
- Damp patches on the reveal after heavy rain
- Rushed sealant from a window installation
Managing a site like Wivelsfield Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.

Why it’s worth doing now in Wivelsfield Green
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished. In a small place like Wivelsfield Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
Why book with us
- Fully insured
- Colour picked to suit the job
- Quality sealants from Arbo and Everbuild
- A choice of colours where the product allows

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Repaint timber before it’s bare
- Look round the frames every year or so
- Don’t use solvent cleaners on the joint
- Don’t aim a pressure washer at the joints
Most silicone sealants won’t take paint, so if you’re planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. A new joint closes it up.
Questions from Wivelsfield Green
I let a flat near Wivelsfield station. Can you help?
Yes, we work for letting agents and landlords. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.
Do you cover Wivelsfield Green for window mastic?
Yes. Our work covers London and the South East, and Wivelsfield Green is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing, and we will give you a clear quote.
Do you seal inside as well as outside?
Yes. Draughts often come through the inside gap too, so it can be worth sealing both.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in.
Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
Can you reach windows above the ground floor?
Yes, where they can be reached safely. Tell us about access when you get in touch and we’ll plan for it.
How long should I leave it?
Cure times vary by product and the temperature. Before we leave, we will tell you the cure time.
Can resealing stop a draught around my window?
Yes, where the draught is at the frame edge. We check where the draught is before any work starts.
Surface by surface
Patio & French doors
Heavy door frames can move more than windows. A flexible sealant copes with that, where a rigid one would crack.
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. If we find rot, we will tell you before going ahead, as a joiner will need to deal with it.
DIY versus a professional finish
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.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
The process
You do not need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the job takes a few hours for a handful of frames, longer for a whole house for a typical job. Somewhere as small as Wivelsfield Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Getting ready for the visit
- Mention if the joints have been sealed before
- Keep children and pets away from the work area
- Clear the area around the work
