About our window mastic in Willington
The mastic around a window or door seals the gap between the frame and the wall. When it cracks, hardens or pulls away, draughts and rain get in. Our applicators cut it out and replace it with a flexible, weatherproof sealant. If you’re dealing with a bead that doesn’t match the frame and draughty joints inside around the window, we can put it right, on window sills, uPVC windows and timber windows & doors alike.
In smaller places like Willington, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. The right sealant depends on the frame and on what it sits in.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

Landlords, agents and businesses in Willington
We also work for property managers and facilities teams. We can quote a run of properties together, and we’re fully insured.
Failed sealant is one of the commonest items on a check-out report. Several properties can go on one quote.
Honest limits
Sealant is not the answer to every problem, and we will tell you before work begins. Sealant won’t put right:
- Penetrating damp from a failed cavity tray or render
- A frame that has rotted at the joint
- Misting between the panes of a double-glazed unit (that needs a new unit)
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think before you book.
Where we work in Willington
- Patio & French doors
- Composite doors
- uPVC windows
- Aluminium frames
- Timber windows & doors
- Window sills
Different surfaces, different methods
uPVC windows
We clean the frame edge carefully so the plastic is not marked, then the new bead is laid against the frame and the wall.
Composite doors
Draughts round the door leaf usually come from worn seals or adjustment, not the mastic. We seal the frame and let you know about anything else.
Quotes for window mastic in Willington
There’s no set price list. The quote depends on:
- Any mould that needs treating
- Working hours on commercial sites
- The type of sealant required
- The number of rooms or windows
Combining jobs into one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
What we need to know
You do not need to know the technical terms. Just tell us:
- How we’d reach the joints
- The rough size of the job
- Photos by email, if that’s easy
- Where the job is, and your postcode
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.
Common problems we fix in Willington
Timber windows bring their own problems. Mastic painted over many times cracks with the paint, and the wood moves with damp as well as heat.
These are the problems we’re asked about most:
- Gaps left after new windows were fitted
- Cracked or shrunken mastic around the frame
- Old mastic that has gone black or come away
- Cold air getting in at the frame edge
Letting a property close to Bearsted station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

What we do, step by step
You do not need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the work takes most of a day for a typical house, less for a few frames in most cases. Parking around Willington is usually easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We check how each frame can be reached safely.
- 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.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- On commercial sites, let us know about site rules
- Clear items away from the joints we’re working on
How to get a quote
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. When it suits you, phone 0345 464 0079 or email us.

Window mastic in Willington: local notes
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Stoneacre (about 0.9 miles east) are a reminder that the area around Willington has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
If you live in an older home near St Martin's Church, the joint between an old wall and a newer frame is normally the first place rain gets in. If you look after a building such as Senacre Wood Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Aftercare tips
So the new joints stay in good condition:
- Avoid harsh chemicals near the mastic
- Clean frames with a soft cloth and soapy water
- Clear any debris from frame drain holes
- Don’t aim a pressure washer at the joints
Check the drainage slots in the frames aren’t blocked, so water can run away instead of sitting against the joint.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
