How the job changes by surface
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. We cut it out, back any deep gaps and reseal properly.
Composite doors
A composite door generally sits in a plastic outer frame, and the joint around it is sealed like a window. The bead is colour-matched to the frame.
Window mastic for homes and businesses in Curteis' Corner
There are two joints on most windows. Outside, the mastic keeps rain out; the internal joint closes the gap to the plaster and stops draughts. Either or both can be done. If you have rain getting in at the frame or under the sill and mastic that’s falling out in pieces, we can put it right, on timber windows & doors, window sills and aluminium frames alike.
Somewhere as small as Curteis' Corner, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
Whatever the size of the job, it’s backed by our 12-month guarantee in Curteis' Corner and across Kent.

How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Clear any debris from frame drain holes
- Don’t aim a pressure washer at the joints
- Keep timber frames painted
- Wipe condensation off the frames
Wipe the frames with soapy water when you clean the windows, and avoid solvent cleaners on the sealant.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Housing providers, facilities teams and property managers book us too in Curteis' Corner and across Kent. We can quote a run of properties together.
Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Questions from Curteis' Corner
Is Curteis' Corner in your area for window mastic?
Yes, Curteis' Corner is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or send us an email and let us know what needs doing, and we’ll give you a clear price.
Do you cover smaller places like Curteis' Corner?
Yes. Curteis' Corner is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is the new sealant paintable?
Silicone generally will not take paint. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
How much does window mastic cost in Curteis' Corner?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before any work starts.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before resealing.
What do you need from me for a quote?
The location, the problem and the rough size of the job. Photos by email help too.
Can you seal the gap between the frame and the plaster indoors?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We do one or both.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us.
What we’re called out for in Curteis' Corner
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, while a joint packed solid can’t stretch. That’s what backing rod is for.
Keep an eye out for any of the following:
- Cracked or shrunken mastic around the frame
- Untidy mastic left by window fitters
- Damp patches on the reveal after heavy rain
- Cold air getting in at the frame edge
If you let a flat or house near Headcorn station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
Questions to ask before you book

- First, we confirm safe access to each frame.

- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit

Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For site and facilities teams at buildings such as John Mayne Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages. Homes close to Parish Church of All Saints include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What sealant work cannot fix
Sealant isn’t the answer to every problem, and we’d rather say so up front. It won’t solve:
