About our window mastic in Kearsney
Whether it’s one leaking patio door or every frame on the house, you will get a clear quote before work begins. Just ring 0345 464 0079 or send us an email and tell us how many frames there are and how they’re reached. If you have rain getting in at the frame or under the sill and whistling draughts around closed windows, we can help, whatever the surface.
Around Kearsney, conservatories, garden rooms and patio doors are often part of the house. Their glazing joints and frame seals are as much a part of the job as the windows, and any older timber or sash windows need a sealant that suits them.

Common problems we fix in Kearsney
A lot of older mastic was never designed to stay flexible. Once it’s rigid, every bit of frame movement pulls at it, leaving a hairline gap down one side.
If you can see any of these, it’s time to have the joints looked at:
- Leaking joints at the ends of sills
- Mastic that has split away from the wall
- A bead that doesn’t match the frame
- Gaps left after new windows were fitted
Letting a property close to Kearsney station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

What the job involves on each surface
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A neat, narrow bead in a colour to match suits the frame.
Patio & French doors
Heavy door frames can move more than windows. A flexible sealant copes with that.

Should I try it myself first?
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Questions from Kearsney
I let a flat near Kearsney station. Can you help?
Yes. We work for landlords and agents as well as homeowners. Just ring 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear price.
Is window mastic in a coastal place like Kearsney any different?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Can I paint over the new sealant?
It depends on the sealant. Some hybrid sealants can be painted; silicone cannot. Tell us if you are decorating and we will choose accordingly.
Can you seal over the old sealant?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us, and we’re fully insured.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Can I add another job to the visit?
Yes. Just list everything you need and we’ll quote it together.
The process
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a morning for a couple of windows and a door. Parking around Kearsney is generally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- 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
- Keep pets and children clear of the area while we work
- Move anything stored near the joints
- Tell us if parking is tricky

Why it’s worth doing now in Kearsney
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. Around Kearsney, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.
Why us?
- Over 20 years’ experience
- Any old sealant cut out fully, not covered over
- Neat joints and a tidy finish

Frames and glazing around Kearsney
Kearsney is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around window and door frames, especially on the side facing the sea. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as Church of St Peter and St Paul, the joint between an old wall and a newer frame is normally the first place rain gets in. If you look after a building such as Temple Ewell Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s.
