About our window mastic in Throwley
Homes in Throwley have every kind of window: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We work on window sills, uPVC windows and composite doors, and people most often call us about gaps where the sill meets the wall and whistling draughts around closed windows.
Homes in small places like Throwley often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
Your job is guaranteed for a year, as with all our work.

Quotes for window mastic in Throwley
We quote each job individually. These are the things that affect it:
- The amount of work
- How much old sealant there is and how hard it is to remove
- Mould in or behind the old joints
- When we can work, for business premises
Combining jobs into one visit is normally more efficient than separate visits. You will get one clear quote for the whole job.
What we need to know
To help us quote quickly, let us know:
- The problem you’ve noticed
- Any access issues, like height or stairs
- Photos by email, if that is easy
- Where the job is, and your postcode
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. Whenever you’re ready, call 0345 464 0079 or send us an email.
Why deal with it now?
Running fresh sealant over the old joint is tempting, but it won’t grip old, dirty sealant. It soon lifts and the leak carries on behind it. The old mastic has to come out. Older cottages and farmhouses around Throwley can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please ring 0345 464 0079 or email us.

Throwley: your questions answered
Can you help a landlord with a rental near Faversham station?
Yes, we work for landlords and agents. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.
Do you cover smaller places like Throwley?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
What should I tell you?
Just the basics: where it is, what you’ve noticed and how we reach it. Then phone 0345 464 0079 or email us.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
Can you do upstairs windows?
Usually, yes. We plan safe access before the job, so mention the height and anything in the way.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. We remove it all first.
What we do, step by step
We keep the work tidy and contained to the area we are working on, so you can carry on as normal. Expect the work to take a few hours for a few frames, or a day or more for a whole house, and we tell you how long to leave it before we go. For a village or hamlet like Throwley, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First we look at every frame and agree the list.
- The old mastic is cut out and the surfaces cleaned back.
- Where gaps are deep, backing rod goes in first.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Mention any tricky access
- Let us know about parking restrictions

Related advice
Different surfaces, different methods
Composite doors
Draughts round the door leaf usually come from worn seals or adjustment, not the mastic. We will tell you if that is what we find.
Window sills
Where a sill meets brick or render, the ends often crack first. We reseal them so rain can’t run into the wall.
Aftercare tips
A little care helps the new joints last. Our advice:
- Look round the frames every year or so
- Keep timber frames painted
- Clear any debris from frame drain holes
- Do not paint over the silicone
Silicone can’t normally be painted, so if you are planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.
When it is not the sealant
We’ll always be straight with you, so here’s what new sealant won’t do:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Faulty window hardware
- Worn gaskets, brush seals or a door that has dropped
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly.
Surfaces we seal
- Timber windows & doors
- Aluminium frames
- Composite doors
- Patio & French doors
- uPVC windows
- Window sills
Can I do it myself?
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What window mastic looks like in Throwley
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. Historic houses like Belmont House and Gardens (about 0.6 miles north-west) are a reminder that the area around Throwley 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.
Rented homes near Faversham station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. In the older streets around Church of St Michael and All Angels, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
