A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.

How we handle window mastic in Puddle Dock
Some gaps around frames are far deeper than they look. Filling it with sealant alone leaves a joint that cannot move properly, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. We work on composite doors, uPVC windows and patio & French doors, and the jobs we see most are leaking joints at the ends of sills and gaps between the frame and the inside reveal.
Many London homes are flats, with windows high above the street. In a converted house or block, the lease usually says who is responsible for the windows, so it’s worth checking before booking.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

What window mastic looks like in Puddle Dock
Historic houses like Hare Hall (about 4.1 miles north-west) are a reminder that the area around Puddle Dock has older buildings as well as new. 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. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In the older streets around Moor Lane Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For site and facilities teams at buildings such as The James Oglethorpe Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Around Puddle Dock
Typical jobs here are in homes near Hall Mead School and the streets around them. For rail, the closest station is Upminster station, roughly 1.9 miles west of the centre.

When to call us in Puddle Dock
Water runs down the glass onto the sill, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
Most people get in touch after spotting something like this:
- Gaps where the sill meets the wall
- Whistling draughts around closed windows
- Mastic that has split away from the wall
- Mastic that is falling out in pieces
Rented homes near Upminster station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

How it works
At the end, we look at the finished work together. The work normally takes a few hours for a handful of frames, longer for a whole house, depending on how much there is to do. For a job in Puddle Dock, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.
Before we arrive
- Let us know about earlier repairs to the joints
- Clear the area around the work
- Keep pets and children clear of the area while we work

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, 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.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
Common questions in Puddle Dock
Is parking a problem for a job in Puddle Dock?
Parking in Puddle Dock, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Can you help a landlord with a rental near Upminster station?
Yes. We work for letting agents and landlords as well as homeowners. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before resealing.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us, and we’re fully insured.
Do you guarantee window mastic?
Yes. Each job is covered for 12 months.
Can you do the inside joint as well?
Yes. Draughts often come through the inside gap too, so sealing both is often worthwhile.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you do not need to watch us work.
What affects the cost of window mastic
We quote each job individually. This is what makes a difference:
- Access and height
- When we can work, for business premises
- Any mould that needs treating
- How many rooms, windows or areas are involved
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.
What to tell us for a quote
Photos by email are helpful but not essential. Please mention:
- If it’s domestic, commercial or a hotel
- What’s wrong with the joints now
- Whether it has been sealed before
- Pictures of the joints, sent by email
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, phone 0345 464 0079 or send us an email.
Different surfaces, different methods
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so the joint must stay flexible. The paint or stain needs to be sound where the sealant meets it.
Window sills
Masonry sills can have joints where water gets in, and the joint under the frame can let rain run behind. Those are sealed with a product suited to stone or concrete.
Leave it or put it right?
Running fresh sealant over the old joint is tempting, but it will not grip old, dirty sealant. It soon lifts and the leak carries on behind it. The old mastic has to come out. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
The cost depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before we start.
