Window & door mastic in Matfield, Kent
Problem with your window and door frames in Matfield? We remove the old material, prepare the joints and seal them properly, with a 12-month guarantee.
- Sealant in the wrong colour for the frame
- Cracked internal joints between frame and plaster
- Mastic that is falling out in pieces
What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a few frames, or a day or more for a whole house. Somewhere as small as Matfield, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check each frame and agree which ones need doing.
- Next the failed sealant is cut away and the joint cleaned.
- 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.
How to prepare
- Tell us about any water getting in
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any sign-in or site rules at work premises

Advice
Window mastic in Matfield, done properly
Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We are ARBOMaster approved and fully insured, and every job is covered by a 12-month guarantee. We work on window sills, timber windows & doors and uPVC windows, and people most often call us about mastic that has split away from the wall and draughty joints inside around the window.
Homes in small places like Matfield 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.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

The cost reflects the work involved, not guesswork. That is why we ask a few questions first and agree the price before starting.

- A few pictures by email, if you can
- If it’s domestic, commercial or a hotel

Getting a quote is simple: let us know the job and the location, and roughly how big it is. A few photos by email make the job easier to understand.
Common problems we fix in Matfield
Older frames were often sealed with products that set hard. Once it’s rigid, every bit of frame movement pulls at it, and a gap opens along one edge.
Keep an eye out for any of the following:
- Mastic that is falling out in pieces
- Cracked internal joints between frame and plaster
- Gaps left after new windows were fitted
- Draughts coming in around windows and doors
If you live in an older home near Ebenezer Church (Matfield), frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Check the mastic once a year
- Repaint timber before it’s bare
- Paint up to the joint, not over it
- Keep jet washers away from the mastic
Most silicone sealants will not take paint, so mention any painting plans before any work starts. We can use a paintable sealant where that matters.
Leaks usually show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
What we cannot put right
It helps to know what we can’t do:
- Damp problems in the wall away from the window
- Condensation trapped between the panes
- Draughts through the window seals rather than the frame
Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly before you book.

What window mastic looks like in Matfield
Historic houses like Scotney Castle (about 4.5 miles south) are a reminder that the area around Matfield 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 is traditional sand mastic. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you let a flat or house near Paddock Wood station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Managing a site like Brenchley and Matfield Church of England Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

Matfield: your questions answered
Do you work for landlords with property near Paddock Wood station?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can go on one quote. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Can you do window mastic in Matfield?
Yes, Matfield is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we will send you a clear quote.
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, while a short indoor joint may be within reach.
Do you have insurance?
Yes. We’re fully insured.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Can you quote for more than one area?
Yes, we can. More than one area can go on one quote.
Will resealing my frames help with draughts?
Often, yes. Air often gets in between the frame and the wall, and resealing inside and out closes it.
What happens if it’s left?
Resealing frames is a short job: it takes a few hours for a handful of frames, longer for a whole house. Leave it until water is coming in and you may need plastering and decorating as well. Older cottages and farmhouses around Matfield can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.
