Window mastic in Hankham
Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We are fully insured ARBOMaster approved applicators, and every job is covered by a 12-month guarantee. We work on patio & French doors, composite doors and aluminium frames, and the jobs we see most are rushed sealant from a window installation and mastic that’s falling out in pieces.
Mastic can only go onto a dry, clean joint, so window work in Hankham is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
All our work is covered by a one-year guarantee, wherever you are in East Sussex.

When it is not the sealant
A few problems are outside what sealant work can do:
- Soft or decayed wood in the frame
- Draughts through the window seals rather than the frame
- Faulty window hardware

What we do, step by step
There isn’t much for you to do on the day. Point us to the joints and we’ll get on with it. The work itself takes most of a day for a typical house, less for a few frames. Somewhere like Hankham 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.
- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Finally we tidy up and check each joint.
Getting ready for the visit
- Clear items away from the joints we are working on
- For indoor joints, keep the area dry beforehand if you can
- Tell us about any water getting in

It all starts with a short chat. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. Whenever you’re ready, phone 0345 464 0079 or drop us an email.

Windows and doors in Hankham
Hankham is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around window and door frames, especially on the side facing the sea. With historic houses such as Michelham Priory (about 4.4 miles north-west) nearby, there’s older building stock in the area around Hankham as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Homes close to St Luke's Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you let a flat or house near Pevensey & Westham station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Hankham: your questions answered
Is Hankham within the area you cover?
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.
I let a flat near Pevensey & Westham station. Can you help?
Yes, we work for landlords and agents. Just call 0345 464 0079 or send us an email and tell us about the property, and we’ll send you a clear quote.
Is it OK to seal over old sealant?
No, because it fails. We remove every bit of old sealant first.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
How many windows can you do in a day?
That depends on the number of frames, how they’re reached and the state of the old mastic. You’ll know the timing when we quote.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned.
Can you do several jobs on one visit?
Yes. Just list everything you need and you’ll get one quote.
Why deal with it now?
The work is quick compared with the damage it prevents: it takes a few hours for a few frames, or a day or more for a whole house. Wait for damp to appear and there may be plaster and decorating to sort out too. Where a wall is exposed, as many are in small places like Hankham, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Signs you need window mastic in Hankham
Water runs down the glass onto the sill, and the ends of the sill, where it meets the wall, are where it gets in. Failed sealant there lets rain into the wall or behind the frame.
Keep an eye out for these signs:
- A bead that doesn’t match the frame
- Water coming in at the bottom corners of a door
- Hard, cracked sealant around windows
- Cold air getting in at the frame edge
For site and facilities teams at buildings such as Hankham Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Surface by surface
Window sills
The end joints of a sill tend to fail before the rest. We reseal them so rain cannot run into the wall.
Composite doors
An exposed front door gets wind-driven rain, and the top and bottom corners tend to fail first. We pay most attention there.
