About our window mastic in Doddington
Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We’re ARBOMaster approved and fully insured, and every job is covered by a 12-month guarantee. We work on composite doors, uPVC windows and patio & French doors, and the jobs we see most are white mastic on grey or black frames and black, perished sealant on frames.
Somewhere as small as Doddington, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

Why it’s worth doing now in Doddington
Once mastic fails, rain can get between the frame and the wall. Over time that can mean damp patches, damaged plaster and rotting timber. Resealing now is a small job by comparison. Older cottages and farmhouses around Doddington can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we will go through it with you.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that is fine. We cut it out and start again.

What window mastic looks like in Doddington
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Belmont House and Gardens (about 3.3 miles east) are a reminder that the area around Doddington has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you let a flat or house near Teynham station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

How the visit works
Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes anything from an hour or two to a full day, depending on how many frames there are. In a small place like Doddington, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.
- We fit backing rod in deep gaps so the sealant is the right depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Every joint is checked before we leave.
Preparing for the visit
- Mention if the joints have been sealed before
- For business premises, tell us about site rules or sign-in
- Move anything stored near the joints

FAQs for Doddington
Will you come out to Doddington?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

What does window mastic cost?
Size, access and the old material all affect the cost. Ask us for a quote and we will talk you through it.
How many windows can you do in a day?
It depends on access, the old mastic and the size of the frames. We’ll tell you how long your job needs when we quote.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Is it OK to seal over old sealant?
No, it won’t last. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Common problems we fix in Doddington
Some failures date back to when the windows were fitted. Sealant run over dust, wet brick or loose mortar didn’t grip properly, so it comes away long before its time.
The most common problems we see are:
- Old mastic that has gone black or come away
- Untidy mastic left by window fitters
- Mastic that has split away from the wall
- Damp patches on the reveal after heavy rain
In the older streets around Church of the Beheading of St John the Baptist, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Surface by surface
Aluminium frames
Coated aluminium needs a compatible sealant and we avoid acetoxy silicones, which can react with some metals. Neutral-cure sealant is the safe choice.
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. It comes out, deep gaps get backing rod and the joint is resealed.
