About our window mastic in Shirley Oaks
From a single sill to a whole house of windows, the work is priced before anything is done. To get one, call 0345 464 0079 or drop us an email with the number of frames and any access details. If you’re dealing with rain getting in at the frame or under the sill and sealant in the wrong colour for the frame, we can put it right.
From mansion-block windows to modern glazing in new flats, London has every kind of frame. Over the years, the sealant around them shrinks, cracks and pulls away, which is when draughts and damp patches appear in homes in Shirley Oaks.
You are covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

What window mastic looks like in Shirley Oaks
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking.
For an older house near a landmark such as Shirley Methodist Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Shirley Oaks is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Your questions about window mastic in Shirley Oaks
Is parking an issue for window mastic in Shirley Oaks?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
Do you work for landlords with property near Elmers End station?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Where are you based?
We work from Crawley. Our applicators cover Shirley Oaks.
Can resealing stop a draught around my window?
Yes, where the draught is at the frame edge. We check where the draught is before work begins.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done and we’ll quote it together.
The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a morning for a couple of windows and a door. For a job in Shirley Oaks, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- 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.
- We tool each bead neatly and check every joint is closed.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Mention if the joints have been sealed before
- Keep pets and children clear of the area while we work

Advice
Landlord and commercial work in Shirley Oaks
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Why act early in Shirley Oaks
Resealing frames is a short job: the visit takes most of a day for a typical house, less for a few frames. Leave it until water is coming in and you may need plastering and decorating as well. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Shirley Oaks, the repair is bigger than the sealant job would have been.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and agree the price before starting.
Why us?
- 20+ years of sealant experience
- Anti-fungal silicone where joints get wet
- A sealant colour to suit the surroundings
- Every job guaranteed for a year

Signs you need window mastic in Shirley Oaks
Plenty of failed mastic was poorly applied in the first place. Sealant run over dust, wet brick or loose mortar never bonded as it should, and it lets go sooner than it should.
If you can see any of these, it’s time to have the joints looked at:
- Rain getting in at the frame or under the sill
- Hard, cracked sealant around windows
- Rushed sealant from a window installation
- Gaps where the sill meets the wall
Managing a site like Oasis Academy Shirley Park? Then larger buildings have plenty of frames, and the mastic around each one ages.

Surface by surface
Composite doors
An exposed front door gets wind-driven rain. Those corners get the most care.
Timber windows & doors
Timber moves with moisture as well as heat, so the joint must stay flexible. The paint or stain needs to be sound where the sealant meets it.
