About our window mastic in Yeading
Frames and walls don’t move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. We work on window sills, composite doors and uPVC windows, and people most often call us about mastic that has split away from the wall and leaking joints at the ends of sills.
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, letting in draughts and water.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Frames and glazing around Yeading
In a converted house or block, who looks after the windows depends on the lease, so it’s worth checking before booking. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Southall station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Managing a site like Brookside Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.

Yeading: your questions answered
Is parking an issue for window mastic in Yeading?
Parking in Yeading, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Is Yeading in your area for window mastic?
Yes, Yeading is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or email us with a few details of the job.
Do you remove the old sealant?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We’ll tell you what we’re using and why.
Can tenants book the work?
Of course. Ask your landlord first, and we can send them the quote if that helps.
Can you quote for more than one area?
Yes. Just list everything you need and we’ll quote it together.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
Can you get sealant to suit coloured frames?
Normally, yes. Tell us the frame colour when you get in touch and we’ll use the nearest match.
What we do, step by step
When we arrive, we look over the joints with you first. We protect the surfaces around the joints before we start. The work normally takes a morning for a couple of windows and a door. In Yeading, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Getting ready for the visit
- Tell us if parking is tricky
- Clear the area around the work
- For indoor joints, keep the area dry beforehand if you can
Ask for a quote
Every job is quoted individually, so the first step is telling us about yours. Just call 0345 464 0079 or send us an email with the details and send pictures if you have them.
Advice
How to look after the new joints
After the cure time, these simple habits help:
- Keep solvents and bleach off the sealant
- Keep timber frames painted
- Avoid blasting the frames with a pressure washer
- Make sure the drainage slots aren’t blocked
On timber frames, keep the paintwork in good order, because bare, wet timber moves more and pulls at the joint. Paint up to the joint, not over the silicone.
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. Any of these is worth a call.
Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
When something else is needed
Before you book, it’s worth knowing the limits too:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Broken hinges, locks or handles
- Worn gaskets, brush seals or a door that has dropped
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly.
What we seal
- Timber windows & doors
- Aluminium frames
- uPVC windows
- Window sills
- Patio & French doors
- Composite doors
Different surfaces, different methods
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. We cut it out, back any deep gaps and reseal properly.
Timber windows & doors
Soft or rotten wood cannot be sealed successfully. We will point out any rot we find, as a joiner will need to deal with it.
Quotes for window mastic in Yeading
You will get a clear quote before any work starts. It’s based on:
- Whether there’s mould to deal with
- How much old sealant there is and how hard it is to remove
- The number of rooms or windows
- Which sealant suits the joint
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Helping us quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- If it’s domestic, commercial or a hotel
- How we’d reach the joints
- The address or postcode of the job
- Whether it has been sealed before
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. When it suits you, phone 0345 464 0079 or send us an email.
Signs you need window mastic in Yeading
A lot of older mastic was never designed to stay flexible. Once it’s rigid, every bit of frame movement pulls at it, and a gap opens along one edge.
Look out for these signs:
- Gaps left after new windows were fitted
- Hard, cracked sealant around windows
- Gaps where the sill meets the wall
- A bead that doesn’t match the frame
Homes close to St Joseph the Worker & Dovetail Centre include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
