Aftercare tips
Aftercare is simple, and it makes a real difference:
- Don’t aim a pressure washer at the joints
- Repaint timber before it’s bare
- Use gentle cleaners on frames and sealant
- Do not paint over the silicone
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
Windows and doors in Little Dunmow
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.
For an older house near a landmark such as Church of St Mary the Virgin, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Managing a site like The Flitch Green Academy? Then the mastic around its windows and doors needs looking after like any other building’s.

What we do, step by step
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a morning for a couple of windows and a door and we leave things clean and tidy. Parking around Little Dunmow is normally 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.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Mention any leaks or damp you’ve noticed
- Keep children and pets away from the work area

FAQs for Little Dunmow
Will you come out to Little Dunmow?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is window mastic in Little Dunmow guaranteed?
Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
Do you work on first-floor windows?
Yes, where they can be reached safely. Tell us about access when you get in touch and we will plan for it.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Can you do several jobs on one visit?
Yes, we can. More than one area can be quoted together.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
When something else is needed
It helps to know what we cannot do too:
- A sash or casement that will not close properly
- A door that needs adjusting, rehanging or new seals
- Rotten timber, which needs a joiner first
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly before booking.
What we seal
- Timber windows & doors
- uPVC windows
- Patio & French doors
- Window sills
- Aluminium frames
- Composite doors
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.

What happens if it’s left?
The work is quick compared with the damage it prevents: the visit takes a few hours for a handful of frames, longer for a whole house. Leave it until water is coming in and you may need plastering and decorating as well. In a smaller place like Little Dunmow, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.
Why us?
- White, clear, grey or coloured to suit, where the product allows
- Old sealant always removed completely
- 4.9 on Google from 180+ five-star reviews
- Experience in homes, commercial sites and hotels
What affects the quote in Little Dunmow
There’s no set price list, because no two jobs are the same. The quote depends on:
- Which sealant suits the joint
- Working hours on commercial sites
- Whether there’s mould to deal with
- Access and height
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.
What we need to know
You don’t need to know the technical terms. It helps if you can tell us:
- If it’s domestic, commercial or a hotel
- The address or postcode of the job
- The problem you’ve noticed
- If someone has resealed it before
