Window & door mastic in Pembury, Kent
Mastic around window and door frames, sills and patio doors for householders, landlords and businesses in Pembury. Fully insured, ARBOMaster approved and guaranteed for a year.
- Leaking joints at the ends of sills
- Draughts coming in around windows and doors

Can I do it myself?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Window mastic for homes and businesses in Pembury
Over two decades of sealing frames has taught us which products suit which walls. We are fully insured ARBOMaster approved applicators, and every job is covered by a 12-month guarantee. Common call-outs are for black, perished sealant on frames and water coming in at the bottom corners of a door, across composite doors, timber windows & doors and window sills.
Many houses in smaller places like Pembury have conservatories, garden rooms or patio doors. Their glazing joints and frame seals are as much a part of the job as the windows.
All our work is covered by our 12-month guarantee.

Aftercare tips
Good habits help new joints last longer. A few tips:
- Do not aim a pressure washer at the joints
- Keep paint off silicone joints
- Keep drainage slots and sill grooves clear
- Wash the frames with mild soapy water
Try not to touch the new joint while it cures, following the cure time we give you. Do not point a pressure washer at the joints.
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 it pays to reseal before that happens.
What window mastic looks like in Pembury
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as Pembury School, the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near High Brooms station, renewing tired window mastic between tenants heads off draught and damp complaints.

Questions from Pembury
Do you cover smaller places like Pembury?
Yes. Pembury is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you do window mastic in Pembury?
Yes. Our work covers London and the South East, and Pembury is part of that. Just call 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear quote.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Can new sealant go over the old?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
What information do you need?
Let us know what needs doing and where, plus pictures if you have them. We will ask anything else we need to know.
What does window mastic cost?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Can you do upstairs windows?
Yes, where they can be reached safely. Tell us about access when you get in touch so we can plan the job.
Signs you need window mastic in Pembury
Every frame moves through the day. Sun on a frame makes it expand, and it contracts again overnight, while the brick or render around it hardly moves. A sealant that can’t keep up eventually tears.
Any of these means the joints need attention:
- White mastic on grey or black frames
- Cold air getting in at the frame edge
- Cracked internal joints between frame and plaster
- Leaking joints at the ends of sills
If you live in an older home near Upper Church of St Peter, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Questions to ask before you book
- Is the old sealant removed completely?
- What preparation is included
- How much experience the applicator has
- How long to leave it before use

Asking for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:

What happens if it’s left?
Failed mastic is not a reason to replace sound windows. Where the frames are sound, new mastic generally deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we will say so. In an older home around Pembury, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, call 0345 464 0079 or drop us an email for an honest opinion and a quote.

What we can’t put right
We will always be straight with you, so here’s what sealant cannot fix:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Draughts through the window seals rather than the frame
- Faulty window hardware
If you’re not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer.

What we do, step by step
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take most of a day for a typical house, less for a few frames. In a smaller place like Pembury, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
How to prepare
- Clear items away from the joints we are working on
- For indoor joints, keep the area dry beforehand if you can
- On commercial sites, let us know about site rules
