How we handle window mastic in Swan Street
Every window and door frame has a gap around it, and mastic is what closes it. Once that seal fails, wind and rain find the gap. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We are often asked to deal with gaps left after new windows were fitted and a bead that doesn’t match the frame, on window sills, aluminium frames and composite doors.
Homes in small places like Swan Street often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
All of our work is guaranteed for twelve months, in Swan Street and everywhere else we cover.

How much does window mastic cost in Swan Street?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Can you quote for more than one area?
Of course. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
Signs you need window mastic in Swan Street
Plenty of failed mastic was poorly applied in the first place. Sealant run over dust, wet brick or loose mortar never bonded as it should, so it comes away long before its time.
Most people get in touch after spotting one of these:
- Hard, cracked sealant around windows
- Old mastic that has gone black or come away
- Gaps between the frame and the inside reveal
- Whistling draughts around closed windows
For landlords with property near Chappel & Wakes Colne station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
What affects the cost of window mastic
We quote each job individually. This is what makes a difference:
- Which sealant suits the joint
- How much old sealant there is and how hard it is to remove
- Mould in or behind the old joints
- How many rooms, windows or areas are involved
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
Helping us quote
What to tell us when you ask for a quote:
- Whether it has been sealed before
- How many joints, rooms or windows are involved
- A few pictures by email, if you can
- If it’s domestic, commercial or a hotel
Every job is quoted individually, so start by telling us what you need. Just call 0345 464 0079 or drop us an email with the details and send photos if you have them.
Honest limits
In fairness, there are a few things sealant won’t fix:
- A door that needs adjusting, rehanging or new seals
- A sash or casement that will not close properly
- Damp coming through the wall itself rather than the frame joint
If you’re not sure, just call 0345 464 0079 or email us and we will give you a straight answer before you book.

How the visit works
There is not much for you to do on the day. Show us the job and we will take it from there. The work itself takes a morning for a couple of windows and a door from start to finish. Somewhere as small as Swan Street, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check how each frame can be reached safely.
- All the failed sealant is cut away, 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.
- We tool the joint so water runs off, then clear up.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Clear the area around the work
- Tell us if parking is tricky

Window mastic in Swan Street: local notes
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near Church of St Barnabas, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Managing a site like Chappel Church of England Controlled Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.

How the job changes by surface
Patio & French doors
Heavy door frames can move more than windows. The sealant must cope with it without cracking.
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so a flexible sealant is essential. The paint or stain needs to be sound where the sealant meets it.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Don’t use solvent cleaners on the joint
- Wipe condensation off the frames
- Clear any debris from frame drain holes
- Do not aim a pressure washer at the joints
Wipe the frames with soapy water when you clean the windows, and avoid solvent cleaners on the sealant.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.
