About our window mastic in Eastwick
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. If you are dealing with untidy mastic left by window fitters and mastic that’s falling out in pieces, we can help, on patio & French doors, composite doors and timber windows & doors alike.
Somewhere as small as Eastwick, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
A 12-month guarantee comes as standard, so you are covered after we’ve gone.

For landlords and businesses
We work for letting agents and landlords as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Keep solvents and bleach off the sealant
- Check the mastic once a year
- Repaint timber before it’s bare
- Don’t aim a pressure washer at the joints
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. Resealing closes it.
Eastwick questions
Do you work for landlords with property near Harlow Town station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Is Eastwick within the area you cover?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
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’ll plan for it.
Can you get sealant to suit coloured frames?
Yes. Grey and black frames get grey or black sealant, and wood-effect frames generally suit brown.
Can you do several jobs on one visit?
Yes, we can. More than one area can go on one quote.
Do you take out the old sealant first?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Does the work come with a guarantee?
Yes. Our one-year guarantee covers every job.
How long does it take to reseal the windows on a house?
Allow a morning for a couple of windows and a door. Access and how stubborn the old mastic is affect the time most.
What window mastic looks like in Eastwick
Eastwick is part of Harlow, one of the post-war new towns. With many homes from the post-war decades, replacement windows and doors are common. The mastic around replacement frames ages too, and gaps at sills and frame heads are where water gets in. 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.
Homes close to Church of St Botolph include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Letting a property close to Harlow Town station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

When to call us in Eastwick
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, and a gap filled solid cannot flex. Backing rod sets the right depth.
Common reasons people contact us are:
- Whistling draughts around closed windows
- Gaps left after new windows were fitted
- Old mastic that has gone black or come away
- Cracked sealant at the sill ends
If you look after a building such as Pemberley Academy, its window and door frames need their mastic kept sound, just like a home’s.

- How the joint is cleaned and prepared
- Whether they’re fully insured
- When the joint can take water or movement
- Whether they seal over old material or remove it

What we do, step by step
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take most of a day for a typical house, less for a few frames. For a village or hamlet like Eastwick, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Mention any leaks or damp you’ve noticed
- Move anything stored near the joints

Related advice
Surface by surface
Timber windows & doors
Timber moves with moisture as well as heat, so a flexible sealant is essential. We seal onto sound, dry paintwork or timber.
Patio & French doors
Patio and French doors have the longest joints on most houses. Most leaks start at the bottom corners, so we pay close attention there.
DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Why deal with it now?
Failed mastic isn’t a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. If we find failed glass units or worn seals, we’ll tell you. In a small place like Eastwick, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
