Window & door mastic in East End, Kent
Window mastic in East End from a team with over 20 years’ experience. Rated 4.9 on Google from 180+ five-star reviews.
- Mastic that is falling out in pieces

- A bead that doesn’t match the frame
Do you need window mastic in East End?
Water runs down the glass onto the sill, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
Signs it’s time to call us include:
- Water coming in at the bottom corners of a door
- Whistling draughts around closed windows
- Untidy mastic left by window fitters
- Draughty joints inside around the window
In the older streets around St Margaret's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Window mastic in East End
Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We’re ARBOMaster approved and fully insured, and every job is covered by a 12-month guarantee. If you’re dealing with mastic that’s falling out in pieces and draughty joints inside around the window, we can help.
In a village or hamlet like East End, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

What happens on the day
There isn’t much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes a morning for a couple of windows and a door, including the tidy-up. Somewhere like East End needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Tell us if parking is tricky
- Mention any leaks or damp you’ve noticed

Advice
How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Don’t aim a pressure washer at the joints
- Clear any debris from frame drain holes
- Walk round the house once a year and look at the joints
- Keep paint off silicone joints
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. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.
What affects the cost of window mastic
For a quick quote, just ask. What matters most is:
- Whether old sealant or filler has to be cut out
- Access and height
- The amount of work
- Any working-time requirements on site
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.
What to tell us for a quote
To make quoting easier, let us know:
- The rough size of the job
- The address or postcode of the job
- Photos by email, if that’s easy
- What the problem is, such as mould, gaps, leaks or cracking
Getting a quote is simple: let us know what needs doing and where, and roughly how big it is. Photos by email help us understand the job.
Honest limits
We will always be straight with you, so here’s what new sealant won’t do:
- A sash or casement that will not close properly
- A door that needs adjusting, rehanging or new seals
- Soft or decayed wood in the frame
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly.
What we seal
- uPVC windows
- Patio & French doors
- Timber windows & doors
- Aluminium frames
- Composite doors
- Window sills
Leave it or put it right?
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished. Around East End, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or drop us an email and we will talk you through it.

How the job changes by surface
Patio & French doors
Patio and French doors have the longest joints on most houses. Most leaks start at the bottom corners, so we pay close attention there.
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We will tell you which suits your home.
Your questions about window mastic in East End
Will you come out to East End?
Yes. East End is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you cover East End for window mastic?
Yes, East End is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear price.
I rent my home. Can I book you?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Can resealing stop a draught around my window?
In many cases. The gap between frame and wall is a common source of draughts, and resealing inside and out closes it.
How many windows can you do in a day?
Allow a morning for a couple of windows and a door. Access and how stubborn the old mastic is affect the time most.
Are you fully insured?
Yes, we are fully insured for every job we do.
How long should I leave it?
Cure times vary by product and the conditions. Before we leave, we’ll tell you the cure time.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
East End homes and the weather
With historic houses such as Smallhythe Place (about 5 miles south-east) nearby, there’s older building stock in the area around East End as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. 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.
