How we handle window mastic in Sholing
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We work on composite doors, timber windows & doors and patio & French doors, and the jobs we see most are cold air getting in at the frame edge and mastic that’s falling out in pieces.
Homes around Sholing range from older properties to newer houses, and their windows range just as widely. Each frame material needs the right sealant against the right wall.
We stand behind the work with a one-year guarantee, so you are covered after we have gone.

Sholing homes and the weather
Sholing is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Historic houses like Medieval Merchant's House (about 2.2 miles west) are a reminder that the area around Sholing has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you let a flat or house near Sholing station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Schools such as St Monica Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. Homes close to Church of St Mary include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Your questions about window mastic in Sholing
Do you cover smaller places like Sholing?
Yes, Sholing 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.
Is window mastic in a coastal place like Sholing any different?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are generally the first to need attention.
Will new mastic stop draughts?
It will if the frame joint is the problem. We check where the draught is before any work starts.
Can you get sealant to suit coloured frames?
Yes. We can use white, brown, anthracite grey, black or clear, so the joint suits the frame.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Where do you work from?
We are a Crawley-based firm. Our area covers South East England, London and Scotland.
Does the work come with a guarantee?
Yes. Each job is covered for 12 months, inside or out.
Is it OK to seal over old sealant?
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.
Why it’s worth doing now in Sholing
Resealing frames is a short job: it takes a morning for a couple of windows and a door. Wait for damp to appear and there may be plaster and decorating to sort out too. Around Sholing, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Aftercare tips
A little care helps the new joints last. We recommend:
- Avoid blasting the frames with a pressure washer
- Repaint timber before it’s bare
- Keep drainage slots and sill grooves clear
- Use gentle cleaners on frames and sealant
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.
Leaks generally show up in wet, windy weather, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.
Different surfaces, different methods
Composite doors
If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We will tell you if that is what we find.
Patio & French doors
Door frames take knocks and movement every time the doors are used. The sealant must cope with it, where a rigid one would crack.
What happens on the day
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. It usually takes a few hours for a handful of frames, longer for a whole house. Parking around Sholing is normally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.
- Where gaps are deep, backing rod goes in first.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
Preparing for the visit
- Tell us if parking is tricky
- Tell us about any previous sealing or DIY attempts
- Where the joints are inside, avoid wetting them before we arrive

Should I try it myself first?
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 fails, we can still redo it.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
When it is not the sealant
We’ll always be straight with you, so here’s what new sealant will not do:
- Soft or decayed wood in the frame
- A door that needs adjusting, rehanging or new seals
- A failed sealed unit that has misted up
If in doubt, call 0345 464 0079 or email us and we will say what we think.
