Window mastic in West Drayton, done properly
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 aluminium frames, timber windows & doors and patio & French doors, and people most often call us about draughty joints inside around the window and rushed sealant from a window installation.
London has a lot of flats and conversions, where windows are often on upper floors. Who looks after the outside of the frames can depend on the lease, so check that first.
There’s a 12-month guarantee on every job, whatever its size.

West Drayton homes and the weather
In a converted house or block, who looks after the windows depends on the lease, so it’s worth checking before booking. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Rented homes near West Drayton station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. West Drayton is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. For an older house near a landmark such as Church of St Martin, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Different surfaces, different methods
uPVC windows
We clean the frame edge carefully so the plastic isn’t marked, then the sealant goes in between frame and wall.
Composite doors
Draughts round the door leaf usually come from worn seals or adjustment, not the mastic. We seal the frame and let you know about anything else.
How it works
At the end, we look at the finished work together and explain the cure time. The work normally takes a few hours for a few frames, or a day or more for a whole house, depending on the size of the job. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- We start by checking each window and door with you.
- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Finally we tidy up and check each joint.
Getting ready for the visit
- Plan for the work area to be out of bounds to pets and children
- Mention any tricky access
- Where the joints are inside, avoid wetting them before we arrive

How do I get a quote for window mastic in West Drayton?
Every job is different, so each one gets its own quote. For a quick quote, ring 0345 464 0079 or send us an email with a short description of the job.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Do you have sealant for grey or black windows?
Yes. Anthracite grey, black, brown and white cover most frames, with clear as an option.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Why act early in West Drayton
Running fresh sealant over the old joint is tempting, but new sealant can’t bond to old, crumbling mastic. It peels before long, and water still gets in behind. The old mastic has to come out. 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.
Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We’ll give you a clear price for the lot.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Keep timber frames painted
- Wipe condensation off the frames
- Keep jet washers away from the mastic
- Do not use solvent cleaners on the joint
On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.
Look out for the warning signs: 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.
What sealant work cannot fix
Some problems need a builder, plumber or other trade rather than us:
- Faulty window hardware
- Soft or decayed wood in the frame
- A failed sealed unit that has misted up
If you’re not sure, just phone 0345 464 0079 or email us and we will give you a straight answer.
