Window mastic for homes and businesses in Hollingbourne
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that cannot flex, so we fit backing rod to set the right depth. That way the new bead bonds to the frame and the wall only. If you have rain getting in at the frame or under the sill and mastic that’s falling out in pieces, we can help, on composite doors, patio & French doors and window sills alike.
Homes in small places like Hollingbourne often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
All our work is covered by our one-year guarantee.

Hollingbourne homes and the weather
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Leeds Castle (about 1.3 miles south-west) are a reminder that the area around Hollingbourne has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
In the older streets around All Saints Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Rented homes near Hollingbourne station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. For site and facilities teams at buildings such as Hollingbourne Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Questions from Hollingbourne
Will you come out to Hollingbourne?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is Hollingbourne in your area for window mastic?
Yes, Hollingbourne is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear price.
How long does it take to reseal the windows on a house?
The work takes a few hours for a handful of frames, longer for a whole house. Access and the amount of old mastic make the biggest difference.
Are you insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can you do several jobs on one visit?
Of course. Combining jobs makes good use of the visit.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint.
Do the sealants smell?
There can be a smell while the sealant cures. Ventilation helps.
What affects the quote in Hollingbourne
We don’t publish a price list, because no two jobs are the same. The quote depends on:
- The size of the job
- The old material and how stubborn it is
- Working hours on commercial sites
- Any mould that needs treating
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, call 0345 464 0079 or email us for an honest opinion and a quote.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- What’s wrong with the joints now
- Where the job is, and your postcode
- Pictures of the joints, sent by email
- The type of property
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. Whenever you are ready, ring 0345 464 0079 or drop us an email.
How the job changes by surface
Composite doors
A composite door normally sits in a plastic outer frame, and the joint around it is sealed like a window. We match the colour to the frame.
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A neat, narrow bead in a colour to match keeps the clean look.
DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Why it’s worth doing now in Hollingbourne
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. Around Hollingbourne, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on the amount of work, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Do not use solvent cleaners on the joint
- Paint up to the joint, not over it
- Look round the frames every year or so
- Repaint timber before it’s bare
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.
