About our window mastic in Brightwalton Green
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 are dealing with mastic that’s falling out in pieces and rain getting in at the frame or under the sill, we can help, on patio & French doors, window sills and aluminium frames alike.
Mastic can only go onto a dry, clean joint, so window work in Brightwalton Green is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Big or small, it’s backed by our one-year guarantee.

What we cannot put right
We’ll always be straight with you, so here’s what new sealant won’t do:
- Damp coming through the wall itself rather than the frame joint
- Faulty window hardware
- A door that needs adjusting, rehanging or new seals
If you’re not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.
Joints and surfaces we work on
- Window sills
- Aluminium frames
- Timber windows & doors
- uPVC windows
- Patio & French doors
- Composite doors
Why deal with it now?
Draughts and leaks do not always mean new windows. If the frames and glass are in good order, resealing the joints is often all that is needed. If we find failed glass units or worn seals, we’ll tell you. Around Brightwalton Green, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, call 0345 464 0079 or drop us an email for an honest opinion and a quote.

FAQs for Brightwalton Green
Can you do window mastic in Brightwalton Green?
Yes, Brightwalton Green is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or drop us an email and let us know what needs doing, and we will give you a clear quote.
Is window mastic in Brightwalton Green guaranteed?
All our work, in Brightwalton Green and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
How much does window mastic cost in Brightwalton Green?
It depends on the job, so we quote each one individually. For a quick quote, phone 0345 464 0079 or send us an email and tell us what needs doing and where.
How long will my window job take?
The work takes a few hours for a handful of frames, longer for a whole house. Access and the amount of old mastic make the biggest difference.
Can new window sealant be painted?
That depends on the product. Some hybrid sealants can be painted; silicone can’t. Mention any painting plans before work begins.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.

What affects the quote in Brightwalton Green
There’s no set price list, because jobs vary so much. What we look at:
- The product the joint needs
- Any mould that needs treating
- The number and length of the joints
- How much old sealant there is and how hard it is to remove
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Helping us quote
Photos help, but a description is a good start. Try to tell us:
- The address or postcode of the job
- How many joints, rooms or windows are involved
- Pictures of the joints, sent by email
- How we’d reach the joints
If you are in Brightwalton Green and need window mastic, phone 0345 464 0079 or drop us an email. A short description of the job and where it is helps us quote, and you will get a clear quote before work begins.
For landlords and businesses
Housing providers, facilities teams and property managers book us too. Several sites can go on one quote, and we are fully insured.
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
What window mastic looks like in Brightwalton Green
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to Church of All Saints include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Advice
Do you need window mastic in Brightwalton Green?
Frames are never completely still. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. If the sealant can’t stretch, it splits.
Any of these means the joints need attention:
- Cracked or shrunken mastic around the frame
- Old mastic that has gone black or come away
- Gaps where the sill meets the wall
- Gaps left after new windows were fitted
If you look after a building such as Brightwalton C.E. Aided Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
Questions to ask before booking
- Who does the work, and how experienced they are
- The length of the guarantee
- Which sealant they’ll use, and why
- What insurance they hold
Aftercare tips
So the new joints stay in good condition:
- Use gentle cleaners on frames and sealant
- Air rooms to keep condensation down around windows
- Keep jet washers away from the mastic
- Don’t paint over the silicone
On timber frames, keep the paintwork in good order, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.
