Window & door mastic in Cliffe, Medway
Window and door frames in Cliffe need attention? We remove the old material, prepare the joints and seal them properly.
- Black, perished sealant on frames
- Untidy mastic left by window fitters
- Cracked sealant at the sill ends
Can I do it myself?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
How we handle window mastic in Cliffe
Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We’re ARBOMaster approved and fully insured, and we give a one-year guarantee on the work. Typical jobs include a bead that doesn’t match the frame and whistling draughts around closed windows, on patio & French doors, window sills and aluminium frames.
In a village or hamlet like Cliffe, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
You are covered for a year from the day we finish. If anything isn’t right with it, phone 0345 464 0079 or send us an email.

How it works
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a handful of frames, longer for a whole house. For a village or hamlet like Cliffe, the journey is planned in advance: let us know about lanes, gates and parking. 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.
- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
Preparing for the visit

Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
We also work for property managers and facilities teams in Cliffe and across Medway. We can quote a run of properties together, and we’re fully insured.
When to call us in Cliffe
Joints that are too thin or too deep fail early. A skim of sealant over a wide gap soon tears, and a gap filled solid cannot flex. That’s what backing rod is for.
If you can see any of these, it’s time to have the joints looked at:
- Cracked or shrunken mastic around the frame
- Gaps left after new windows were fitted
- Cracked sealant at the sill ends
- Rain getting in at the frame or under the sill
If you live in an older home near Church of St Helen, the joint between an old wall and a newer frame is generally the first place rain gets in.

Different surfaces, different methods
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We can talk through the options.
Patio & French doors
Heavy door frames can move more than windows. The sealant must cope with it without cracking.
Questions from Cliffe
Does the coastal weather in Cliffe affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Can you help a landlord with a rental near Higham station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or drop us an email and tell us about the property, and we will send you a clear quote.
Do you have sealant for grey or black windows?
Yes, in most cases. Tell us the frame colour when you get in touch and we will use the nearest match.
How long before the joint can be used?
Cure times vary by product and the conditions. We tell you how long to leave it before we go.
Can you seal the gap between the frame and the plaster indoors?
Yes. Plenty of draughts come through the inside joint as well as the outside, so it can be worth sealing both.
Do you work on first-floor windows?
Yes, where it’s safe. Higher or awkward frames may need extra access, and we’ll confirm what’s needed.
How long will my window job take?
It depends on access, the old mastic and the size of the frames. You will know the timing when we quote.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
What happens if it’s left?
A quick bead over the top of old mastic looks like an easy fix, but new sealant can’t bond to old, crumbling mastic. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. Around Cliffe, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, phone 0345 464 0079 or email us and we’ll give you an honest view and a quote.

Cliffe homes and the weather
Cliffe is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around window and door frames, especially on the side facing the sea. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For landlords with property near Higham station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. If you look after a building such as St Helen's Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s.
