West Ealing Window Mastic
Mastic around window and door frames, sills and patio doors for homes and businesses in West Ealing and across Greater London. Fully insured, ARBOMaster approved and guaranteed for a year.
- Draughts coming in around windows and doors
- Old mastic that has gone black or come away
- A bead that does not match the frame
How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Wipe condensation off the frames
- Check the mastic once a year
- Avoid blasting the frames with a pressure washer
- Make sure the drainage slots are not blocked
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
How we handle window mastic in West Ealing
If you can feel air around a shut window, the gap is often at the frame. A new joint stops the air getting through. If the draught is through the window seals instead, we’ll tell you. We are often asked to deal with black, perished sealant on frames and white mastic on grey or black frames, on window sills, timber windows & doors and aluminium frames.
Many London homes are flats, with windows high above the street. Who looks after the outside of the frames can depend on the lease, so check that first.
Every job comes with our 12-month guarantee, wherever you are in Greater London.

Common problems we fix in West Ealing
Joint shape matters as much as the product. A thin smear across a wide gap has nothing to it, while a joint packed solid can’t stretch. That is what backing rod is for.
It’s worth asking for a quote if you see:
- Gaps where the sill meets the wall
- Cracked internal joints between frame and plaster
- White mastic on grey or black frames
- Mastic that is falling out in pieces
Managing a site like St Joseph's Catholic Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.
What to look for in a quote
- What the cure time is
- Is VAT in the price?
- What preparation is included
- Which sealant they’ll use, and why
Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

What we do, step by step
You don’t need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the job takes a few hours for a handful of frames, longer for a whole house for a typical job. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in West Ealing. A visitor permit or a nearby bay makes the visit run more smoothly.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Before we arrive
- Mention any parking rules near the property
- Keep children and pets away from the work area
- Clear the area around the work

What affects the quote in West Ealing
We quote each job individually. This is what makes a difference:
- The size of the job

Combining jobs into one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll give you a clear price for the lot.
Asking for a quote
To help us quote quickly, let us know:
- How many joints, rooms or windows are involved
- What the problem is, such as mould, gaps, leaks or cracking
- Access, such as stairs, a lift or height
- If someone has resealed it before
Quotes start with a quick conversation. Describe the problem, the location and the size of the job. Whenever you are ready, ring 0345 464 0079 or send us an email.
Why act early in West Ealing
If you are painting or rendering, reseal at the same time. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble for homes in West Ealing.
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and give you a clear price before any work starts.

What the job involves on each surface
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.
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. It comes out, deep gaps get backing rod and the joint is resealed.
Window mastic in West Ealing: local notes
With historic houses such as Pitzhanger Manor (about 1.4 miles east) nearby, there’s older building stock in the area around West Ealing as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking.
If you live in an older home near St Mary's Cathedral, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. West Ealing is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
