Surface by surface
Patio & French doors
Not every patio door leak is a mastic problem: blocked drain slots, worn brush seals and threshold details can let water in too. We check before we reseal.
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. We cut it out, back any deep gaps and reseal properly.
Window mastic in Charing Heath, 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’re often asked to deal with cracked sealant at the sill ends and black, perished sealant on frames, across timber windows & doors, window sills and composite doors.
In a village or hamlet like Charing Heath, 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.
There’s a 12-month guarantee on every job, whatever its size.

Window mastic in Charing Heath: local notes
With historic houses such as Godinton House (about 4.7 miles south-east) nearby, there’s older building stock in the area around Charing Heath as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Charing station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

How it works
We work through the job in order: protect, prepare, seal, tidy. Typically it takes anything from an hour or two to a full day, depending on how many frames there are, and the area is left clean. In a small place like Charing Heath, access is generally the main thing to plan. 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
- Clear items away from the joints we’re working on
- For business premises, tell us about site rules or sign-in
- Keep pets and children clear of the area while we work

When to call us in Charing Heath
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.
These are the problems we are asked about most:
- Gaps left after new windows were fitted
- Cracked or shrunken mastic around the frame
- Black, perished sealant on frames
- Draughty joints inside around the window
For an older house near a landmark such as Church of the Holy Trinity, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
What your quote should include
- What guarantee comes with the work
- Who does the work, and how experienced they are
- Which colour the sealant will be
- What the cure time is
Questions from Charing Heath
I let a flat near Charing station. Can you help?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Will you come out to Charing Heath?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
How long before the joint can be used?
It depends on the product and the conditions. Before we leave, we will tell you the cure time.
Will the old sealant be removed?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
How many windows can you do in a day?
A handful of frames is a short visit. You’ll get a timescale with the quote.
What does window mastic cost?
Every job is different, so each one gets its own quote. For a quick quote, ring 0345 464 0079 or email us and tell us what needs doing and where.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Are you fully insured?
Yes. Full insurance covers our work.
Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
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.

What affects the cost of window mastic
You will get a clear quote before any work starts. It’s based on:
- How much old sealant there is and how hard it is to remove
- Any mould that needs treating
- The number and length of the joints
- Which sealant suits the joint
Leaving a failed joint normally makes the job bigger, not smaller. If you are not sure whether it needs doing, call 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
What we need to know
Photos by email are helpful but not essential. Try to tell us:
- Where the job is, and your postcode
- The type of property
- What the problem is, such as mould, gaps, leaks or cracking
- Access, such as stairs, a lift or height
Every job is quoted individually. Just ring 0345 464 0079 or send us an email with the details, and photos are welcome.
Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
