About our window mastic in Ham
Some gaps around frames are far deeper than they look. Packing it solid with sealant gives a joint that can’t flex, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. Typical jobs include whistling draughts around closed windows and gaps between the frame and the inside reveal, on uPVC windows, window sills and composite doors.
Around Ham, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
Whatever the size of the job, you get the same 12-month guarantee.

Window mastic in Ham: local notes
Historic houses like Walmer Castle (about 4.4 miles south-east) are a reminder that the area around Ham has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Sandwich station, renewing tired window mastic between tenants heads off draught and damp complaints. In the older streets around Church of St George, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For site and facilities teams at buildings such as Worth Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

How the visit works
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the work takes a morning for a couple of windows and a door for a typical job. In a small place like Ham, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- 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.
How to prepare
- Move anything stored near the joints
- Let us know if you’ve seen damp or leaks
- Mention any tricky access

Common questions in Ham
Do you cover Ham for window mastic?
Yes. We work across London and the South East, and Ham is part of that. You can ring 0345 464 0079 or drop us an email and let us know what needs doing.
Is Ham within the area you cover?
Yes, Ham is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do I have to be there?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Can you do upstairs windows?
Yes, as long as they can be reached safely. Tell us about access when you get in touch so we can plan the job.
Is the new sealant paintable?
It depends on the sealant. Some hybrid sealants can be painted; silicone cannot. Mention any painting plans before any work starts.
How many windows can you do in a day?
That depends on the number of frames, how they’re reached and the state of the old mastic. We’ll tell you how long your job needs when we quote.
Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Paint up to the joint, not over it
- Look round the frames every year or so
- Wipe condensation off the frames
- Wash the frames with mild soapy water
Silicone cannot normally be painted, so if you are planning to paint the frames or walls, tell us beforehand. There are paintable sealants for joints that need it.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
How we quote for window mastic
For a quick quote, just ask. What matters most is:
- Working hours on commercial sites
- Whether old sealant or filler has to be cut out
- Mould in or behind the old joints
- The type of sealant required
Combining jobs into one visit generally makes better use of the time than several visits. You will get one clear quote for the whole job.
What we need to know
What to tell us when you ask for a quote:
- Roughly how big the job is
- A few pictures by email, if you can
- If someone has resealed it before
- What’s wrong with the joints now
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. Whenever you are ready, ring 0345 464 0079 or email us.

What we cannot put right
We’ll always be straight with you, so here’s what new sealant will not do:
- Worn gaskets, brush seals or a door that has dropped
- A failed sealed unit that has misted up
- Broken hinges, locks or handles
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly before booking.
Where we work in Ham
- Timber windows & doors
- Composite doors
- uPVC windows
- Patio & French doors
- Window sills
- Aluminium frames
How the job changes by surface
Window sills
Stone and concrete sills have their own joints, including the one between the sill and the frame above. Those are sealed with a product suited to stone or concrete.
Patio & French doors
Water at the foot of a door frame isn’t always the mastic: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We check before we reseal.
What happens if it’s left?
If you’re 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. Older cottages and farmhouses around Ham can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and send you a clear quote before we start.
