Common questions in Rough Common
Can you help a landlord with a rental near Canterbury West station?
Yes. We work for letting agents and landlords as well as homeowners. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Will you come out to Rough Common?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you work on first-floor windows?
Yes, if safe access is possible. For high or awkward windows, we’ll tell you what access is needed.
Can I add another job to the visit?
Yes, we can. More than one area can go on one quote.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
What do you put in the joint?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
How long should I leave it?
It depends on the product. We tell you how long to leave it before we go.
How many windows can you do in a day?
That depends on the number of frames, how they’re reached and the state of the old mastic. You will know the timing when we quote.
Window mastic in Rough Common, done properly
Frames and walls don’t move together. Heat and cold make frames grow and shrink against brick or render that hardly moves. So the sealant has to stretch and recover, which is why we use a low-modulus product. We work on uPVC windows, patio & French doors and window sills, and common reasons people get in touch are old mastic that has gone black or come away and whistling draughts around closed windows.
Homes in small places like Rough Common 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.
Each job carries a 12-month guarantee, whatever its size.

Common problems we fix in Rough Common
Plenty of failed mastic was poorly applied in the first place. Sealant run over dust, wet brick or loose mortar didn’t grip properly, and it lets go sooner than it should.
It’s worth asking for a quote if you see:
- Gaps between the frame and the inside reveal
- Cracked sealant at the sill ends
- Untidy mastic left by window fitters
- Black, perished sealant on frames
For site and facilities teams at buildings such as Blean Primary School, its window and door frames need their mastic kept sound, just like a home’s.

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Don’t paint over the silicone
- Walk round the house once a year and look at the joints
- Avoid harsh chemicals near the mastic
- Make sure the drainage slots are not blocked
Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and a cold room gets colder. Resealing closes it.
Window mastic in Rough Common: local notes
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.
If you let a flat or house near Canterbury West station, renewing tired window mastic between tenants heads off draught and damp complaints. If you live in an older home near Church of St. Gabriel, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Why it’s worth doing now in Rough Common
Running fresh sealant over the old joint is tempting, but it will not grip old, dirty sealant. It soon lifts and the leak carries on behind it. The old mastic has to come out. Around Rough Common, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
The process
You don’t need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the work takes anything from an hour or two to a full day, depending on how many frames there are in most cases. Somewhere as small as Rough Common, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check each frame and agree which ones need doing.
- The old mastic is cut out and the surfaces cleaned back.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.
Before we arrive
- Clear the area around the work
- Let us know about stairs, lifts or work at height
- Tell us about any water getting in
