What the job involves on each surface
Window sills
Masonry sills can have joints where water gets in, and the joint under the frame can let rain run behind. Those are sealed with a product suited to stone or concrete.
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, 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.
About our window mastic in Halling
Most frames have an outside joint and an inside one. Outside, the mastic keeps rain out; inside, the joint between frame and plaster stops draughts and tidies the reveal. We seal one or both, depending on what’s needed. Typical jobs include gaps left after new windows were fitted and whistling draughts around closed windows, across composite doors, timber windows & doors and aluminium frames.
Around Halling, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
All our work is covered by our one-year guarantee.

How the visit works
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours for a handful of frames, longer for a whole house. Somewhere as small as Halling, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any leaks or damp you’ve noticed

Advice
Halling homes and the weather
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. With historic houses such as Starkey Castle (about 1 mile north-east) nearby, there’s older building stock in the area around Halling as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Homes close to Church of St John the Baptist include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in. For landlords with property near Halling station, renewing tired window mastic between tenants heads off draught and damp complaints.
Halling is about 3 miles south-west of Rochester, in Medway. Anywhere in ME2, our applicators can take on window mastic. Halling is one of 68 towns and villages in Medway where we work. London is on our list too, around 25 miles away.

Honest limits
A few problems are outside what sealant work can do:
- A door that needs adjusting, rehanging or new seals
- A sash or casement that won’t close properly
- A failed sealed unit that has misted up
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.

Common problems we fix in Halling
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, and a gap filled solid can’t flex. That is what backing rod is for.
If you can see any of these, it’s time to have the joints looked at:
- Draughts coming in around windows and doors
- Draughty joints inside around the window
- Rain getting in at the frame or under the sill
- Gaps left after new windows were fitted
Schools such as Halling Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

Common questions in Halling
Is Halling in your area for window mastic?
Yes. Our work covers London and the South East, and Halling is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing.
Can you help a landlord with a rental near Halling station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.
Is it OK to seal over old sealant?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Can you seal the gap between the frame and the plaster indoors?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We do one or both.
Do you hold any approvals?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Do you work for hotels and businesses?
Yes. We have worked for hotels, offices and other businesses and we’re fully insured.
How long does it take to reseal the windows on a house?
The work takes a few hours for a handful of frames, longer for a whole house. Access and how stubborn the old mastic is affect the time most.
Can new window sealant be painted?
That depends on the product. Some hybrid sealants can be painted; silicone cannot. Tell us if you’re decorating and we will choose accordingly.
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Landlord and commercial work in Halling
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Looking after it afterwards
Aftercare is simple:
- Keep paint off silicone joints
- Ventilate rooms so frames do not stay wet inside
- Walk round the house once a year and look at the joints
- Clear any debris from frame drain holes
Check the drainage slots in the frames aren’t blocked, so water can run away instead of sitting against the joint.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.
