Window mastic for homes and businesses in Easebourne
The mastic around a window or door seals the gap between the frame and the wall. When it cracks, hardens or pulls away, draughts and rain get in. The old mastic is removed and the joint resealed with a flexible exterior sealant. We work on window sills, uPVC windows and aluminium frames, and people most often call us about sealant in the wrong colour for the frame and draughts coming in around windows and doors.
Mastic can only go onto a dry, clean joint, so window work in Easebourne is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Can I do it myself?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
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.
Different surfaces, different methods
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. We will point out any rot we find, as that is a job for a joiner.
Composite doors
Front doors take the weather head on, and the top and bottom corners tend to fail first. We pay most attention there.
Quotes for window mastic in Easebourne
We do not publish a price list, because jobs vary so much. The quote depends on:
- Working hours on commercial sites
- Mould in or behind the old joints
- The type of sealant required
- How many rooms, windows or areas are involved
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.
What we need to know
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Where the job is, and your postcode
- Whether it’s a home or a business
- Any previous sealing or DIY work
- What the problem is, such as mould, gaps, leaks or cracking
Getting a quote is simple: let us know what needs doing and where, and roughly how big it is. Photos by email help us understand the job.
Easebourne homes and the weather
With historic houses such as Cowdray House (about 0.6 miles south) nearby, there’s older building stock in the area around Easebourne as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to The Parish Church of St Mary include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you look after a building such as Easebourne CofE Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can go on one quote.
When it is not the sealant
In fairness, there are a few things sealant will not fix:
- Worn gaskets, brush seals or a door that has dropped
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Rotten timber, which needs a joiner first

The process
When we arrive, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before we start. The work generally takes a few hours for a few frames, or a day or more for a whole house. Somewhere like Easebourne needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- 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.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children

Advice
Easebourne: your questions answered
Will you come out to Easebourne?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Is window mastic in Easebourne guaranteed?
Every job comes with our one-year guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. We remove it all first.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Can I add another job to the visit?
Yes. Just list everything you need and you’ll get one quote.
Will resealing my frames help with draughts?
Yes, where the draught is at the frame edge. We check where the draught is before any work starts.
How long will my window job take?
Allow a few hours for a handful of frames, longer for a whole house. Access and the amount of old mastic make the biggest difference.
What should I tell you?
The location, the problem and the rough size of the job. If you can, email a few pictures.
Why deal with it now?
Getting a straight, even bead on an outside frame takes practice, especially upstairs. A professional job is cut out properly, backed where needed and finished neatly, using a product chosen for the frame and wall. Around Easebourne, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Ask us for a quote and we’ll go through it with you.
