Different surfaces, different methods
Patio & French doors
Door frames take knocks and movement every time the doors are used. A flexible sealant copes with that without cracking.
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We can talk through the options.
Window mastic in Eccles
Behind a thin line of old mastic there’s sometimes a deep void. Filling it with sealant alone leaves a joint that cannot move properly, so deep gaps get backing rod first. The sealant then grips the two sides it should. If you are dealing with cracked or shrunken mastic around the frame and mastic that’s falling out in pieces, we can help, on timber windows & doors, aluminium frames and window sills alike.
Homes in small places like Eccles often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.

What happens if it’s left?
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, using a product chosen for the frame and wall. Around Eccles, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on the size of the job, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.

When something else is needed
In fairness, some problems need a different trade:
- Soft or decayed wood in the frame
- Damp coming through the wall itself rather than the frame joint
- Draughts through the window seals rather than the frame

How do I get a quote for window mastic in Eccles?
It depends on the job, so we quote each one individually. For a quick quote, call 0345 464 0079 or send us an email and tell us what needs doing and where.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Can you seal over the old sealant?
No, it will not last. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint.
Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Check the mastic once a year
- Do not aim a pressure washer at the joints
- Keep paint off silicone joints
- Repaint timber before it’s bare
Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.
On timber windows, water behind the joint can lead to rot. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.
What affects the cost of window mastic
We don’t publish a price list, because jobs vary so much. What we look at:
- Whether old sealant or filler has to be cut out
- The number of rooms or windows
- The type of sealant required
- The size of the job
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.
Helping us quote
You do not need to know the technical terms. Just tell us:
- What’s wrong with the joints now
- The address or postcode of the job
- The rough size of the job
- Whether it has been sealed before
There’s no standard price list, as no two jobs are quite the same. Instead, we give you a clear quote for your job. To get started, phone 0345 464 0079 or send us an email.
Eccles homes and the weather
Historic houses like Starkey Castle (about 3.2 miles north) are a reminder that the area around Eccles has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In the older streets around Church of St Peter and St Paul, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Managing a site like St Mark's Church of England Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near New Hythe station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

How the visit works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a morning for a couple of windows and a door, and the area is left clean. In a small place like Eccles, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- 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.
How to prepare
- Tell us about any previous sealing or DIY attempts
- For indoor joints, keep the area dry beforehand if you can
- Plan for the work area to be out of bounds to pets and children

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Some sealant jobs are within reach of a careful DIYer, 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.
