Window mastic for homes and businesses in Canterbury
Whether it’s one leaking patio door or every frame on the house, you will get a clear quote before we start. Just ring 0345 464 0079 or send us an email and tell us how many frames there are and how they’re reached for window mastic in Canterbury. We work on uPVC windows, timber windows & doors and composite doors, and the jobs we see most are whistling draughts around closed windows and a bead that doesn’t match the frame.
Town-centre flats, shops and offices in Canterbury have long runs of frames and glazing. Failed joints up there let in water that can go unnoticed for a while.
Big or small, it’s backed by our 12-month guarantee.
What we cannot put right
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Penetrating damp from a failed cavity tray or render
- A sash or casement that won’t close properly
- Rotten timber, which needs a joiner first
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think.

The process
We bring everything the job needs with us. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take a morning for a couple of windows and a door. Commercial jobs in Canterbury can be planned out of hours where a building cannot close, while home visits are arranged within our normal working hours, Monday to Saturday.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- 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.
- Every joint is tooled smooth and checked before we leave.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Where the joints are inside, avoid wetting them before we arrive
- Keep pets and children clear of the area while we work

FAQs for Canterbury
Is window mastic in Canterbury guaranteed?
All our work, in Canterbury and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Is Canterbury in your area for window mastic?
Yes, Canterbury is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us and we are fully insured.
I’m a tenant. Can you help?
Of course. Check with your landlord; we can send the quote to them too.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
What should I tell you?
Just the basics: where it is, what you’ve noticed and how we reach it. Then phone 0345 464 0079 or send us an email.
What happens if it’s left?
Running fresh sealant over the old joint is tempting, but it will not grip old, dirty sealant. It peels before long, and water still gets in behind. The old mastic has to come out. For businesses in Canterbury, a room closed because of a leak or mould costs more than the sealant, so failing joints are best replaced on a planned basis.
What it costs depends on how much there is to do, how hard the old material is to remove and access to the work. We give a clear quote before any work starts, so you know where you stand.

What we are called out for in Canterbury
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. Backing rod sets the right depth.
People generally contact us when they notice something like this:
- Sealant in the wrong colour for the frame
- Rushed sealant from a window installation
- Whistling draughts around closed windows
- Water coming in at the bottom corners of a door
Letting a property close to Canterbury East station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
Before you book anyone
- Which sealant they’ll use, and why
- What insurance they hold
- What the quote includes, VAT included or not
- Whether they seal over old material or remove it
How to look after the new joints
So the new joints stay in good condition:
- Check the mastic once a year
- Don’t aim a pressure washer at the joints
- Paint up to the joint, not over it
- Wipe condensation off the frames
Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.
What affects the quote in Canterbury
Call for a quick quote. What matters most is:
- Which sealant suits the joint
- The old material and how stubborn it is
- Any working-time requirements on site
- Mould in or behind the old joints
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.
What to tell us for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Photos by email, if that’s easy
- Access, such as stairs, a lift or height
- How many joints, rooms or windows are involved
- What’s wrong with the joints now
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. Whenever you’re ready, ring 0345 464 0079 or send us an email.
Canterbury homes and the weather
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as St Peter's Methodist Primary School, the mastic around its windows and doors needs looking after like any other building’s. Homes close to Church of St Margaret include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
