Common questions in Kingsley
Will you come out to Kingsley?
Yes. Kingsley is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you do window mastic in Kingsley?
Yes, Kingsley is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll give you a clear quote.
Do you seal inside as well as outside?
Yes, we do both. Indoors, we seal between the frame and the plaster or reveal, using a paintable sealant if you want to decorate.
I’m a tenant. Can you help?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.
Can I add another job to the visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Will the old sealant be removed?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
Are you an approved applicator?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Window mastic in Kingsley, done properly
A cold draught around a closed window often comes from the frame edge. Resealing that joint can make a room feel noticeably less draughty and quietens the whistle on windy days. If the draught is through the window seals instead, we will tell you. If you have water coming in at the bottom corners of a door and gaps where the sill meets the wall, we can put it right, whatever the surface.
Outdoor sealant needs dry, clean surfaces, so work on frames around Kingsley is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

What window mastic looks like in Kingsley
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In the older streets around Church of All Saints, the joint between an old wall and a newer frame is normally the first place rain gets in. For site and facilities teams at buildings such as Mill Chase Academy, the mastic around its windows and doors needs looking after like any other building’s.

What sealant work can’t fix

What the job involves on each surface
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We can talk through the options.
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. We cut it out, back any deep gaps and reseal properly.
How it works
There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes anything from an hour or two to a full day, depending on how many frames there are from start to finish. In a small place like Kingsley, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each window and door with you.
- The old mastic is cut out and the surfaces cleaned back.
- Where gaps are deep, backing rod goes in first.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
How to prepare
- For business premises, tell us about site rules or sign-in
- Mention if the joints have been sealed before
- Let us know if you’ve seen damp or leaks

Related advice
Signs you need window mastic in Kingsley
Joints that are too thin or too deep fail early. A skim of sealant over a wide gap soon tears, and a gap filled solid cannot flex. That is what backing rod is for.
Look out for any of the following:
- Hard, cracked sealant around windows
- Whistling draughts around closed windows
- Draughty joints inside around the window
- Cracked sealant at the sill ends
Rented homes near Bentley (Hampshire) station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.

Aftercare tips
Aftercare is simple, and it makes a real difference:
- Walk round the house once a year and look at the joints
- Keep jet washers away from the mastic
- Keep drainage slots and sill grooves clear
- Avoid harsh chemicals near the mastic
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.
