Window mastic for homes and businesses in East Ilsley
Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We are fully insured ARBOMaster approved applicators, and we give a 12-month guarantee on the work. Typical jobs include draughts coming in around windows and doors and rushed sealant from a window installation, across uPVC windows, aluminium frames and composite doors.
Around East Ilsley, 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.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Common questions in East Ilsley
Is East Ilsley within the area you cover?
Yes. East Ilsley 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.
Is East Ilsley in your area for window mastic?
Yes, East Ilsley 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.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
What should I tell you?
Just the basics: where it is, what you’ve noticed and how we reach it. Then ring 0345 464 0079 or send us an email.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
How long will my window job take?
That depends on the number of frames, how they’re reached and the state of the old mastic. We will tell you how long your job needs when we quote.
Can you seal over the old sealant?
No, it will not last. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
I’m a tenant. Can you help?
We are happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Do you need window mastic in East Ilsley?
Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.
If you can see any of these, it’s time to have the joints looked at:
- Draughts coming in around windows and doors
- Hard, cracked sealant around windows
- Rain getting in at the frame or under the sill
- Gaps left after new windows were fitted
In the older streets around Church of St Mary, the joint between an old wall and a newer frame is usually the first place rain gets in.
Before you book anyone
- Is VAT in the price?
- How hidden problems are handled
- When the joint can take water or movement
- Which colour the sealant will be
What the job involves on each surface
Timber windows & doors
Timber moves with moisture as well as heat, so a flexible sealant is essential. The paint or stain needs to be sound where the sealant meets it.
Patio & French doors
Heavy door frames can move more than windows. A flexible sealant copes with that without cracking.
Windows and doors in East Ilsley
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.
Schools such as The Ilsleys Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will quote.
How it works
We keep the work tidy and contained to the area we’re working on. Expect the work to take a few hours for a handful of frames, longer for a whole house, and we tell you how long to leave it before we go. In a small place like East Ilsley, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- Keep pets and children clear of the area while we work
- Mention any tricky access

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Do not aim a pressure washer at the joints
- Keep paint off silicone joints
- Check the mastic once a year
- Repaint timber before it’s bare
Check the drainage slots in the frames aren’t blocked, so rain drains out rather than building up at the sealant.
Leaks normally show up in wet, windy weather, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
