Window mastic in Tunstall, done properly
Behind a thin line of old mastic there’s sometimes a deep void. Filling it with sealant alone leaves a joint that can’t move properly, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. Typical jobs include sealant in the wrong colour for the frame and mastic that has split away from the wall, across composite doors, window sills and aluminium frames.
Homes in small places like Tunstall often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
All of our work is guaranteed for twelve months, in Tunstall and everywhere else we cover.

Tunstall homes and the weather
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 look after a building such as Tunstall Church of England (Aided) Primary School, the mastic around its windows and doors needs looking after like any other building’s. Homes close to Church of St John the Baptist include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in.
Tunstall is about 1 mile south-west of Sittingbourne, in Kent.

Questions from Tunstall
Can you help a landlord with a rental near Sittingbourne station?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.
Will you come out to Tunstall?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you reach windows above the ground floor?
Yes, as long as they can be reached safely. Let us know about access when you ask for a quote and we will plan for it.
Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
How much does window mastic cost in Tunstall?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
Can you do several jobs on one visit?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a morning for a couple of windows and a door. Somewhere as small as Tunstall, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Mention if the joints have been sealed before
- Let us know about stairs, lifts or work at height
Ask for a quote
Asking for a quote is easy: let us know the job and the location and its rough size. Photos by email help us understand the job, and we will come back to you with a quote.
Advice
Honest limits
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- A sash or casement that won’t close properly
- Condensation trapped between the panes
- Worn gaskets, brush seals or a door that has dropped
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly before booking.

Signs you need window mastic in Tunstall
On timber frames, paint and putty build up around the joint. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
Keep an eye out for any of the following:
- Cracked sealant at the sill ends
- Draughts coming in around windows and doors
- Water coming in at the bottom corners of a door
- Cracked internal joints between frame and plaster
Letting a property close to Sittingbourne station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

- Which sealant they’ll use, and why
- Whether VAT is included
- Whether you can choose the colour
- Whether they seal over old material or remove it

Work for landlords, hotels and businesses
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What affects the cost of window mastic
Every job gets its own quote. This is what makes a difference:
- Access and height
- Which sealant suits the joint
- Whether there’s mould to deal with
- How much old sealant there is and how hard it is to remove
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.
Asking for a quote
Photos by email are helpful but not essential. Try to tell us:
- Any access issues, like height or stairs
- A few pictures by email, if you can
- The type of property
- Where the job is, and your postcode
If you’re in Tunstall and need window mastic, phone 0345 464 0079 or email us. A short description of the job and where it is helps us quote, and we’ll agree the price before any work begins.
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Avoid blasting the frames with a pressure washer
- Keep paint off silicone joints
- Wash the frames with mild soapy water
- Make sure the drainage slots aren’t blocked
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
