How we handle window mastic in Little Oakley
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 we fit backing rod to set the right depth. The sealant then grips the two sides it should. We work on composite doors, timber windows & doors and window sills, and people most often call us about hard, cracked sealant around windows and water coming in at the bottom corners of a door.
Mastic can only go onto a dry, clean joint, so window work in Little Oakley is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Whatever the size of the job, you get the same one-year guarantee in Little Oakley and across Essex.

When it is not the sealant
A few problems are outside what sealant work can do:
- A sash or casement that will not close properly
- Soft or decayed wood in the frame
- Penetrating damp from a failed cavity tray or render
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think.

How to look after the new joints
A little care helps the new joints last. Our advice:
- Keep jet washers away from the mastic
- Clear any debris from frame drain holes
- Keep paint off silicone joints
- Clean frames with a soft cloth and soapy water
Timber frames need their paint kept up, because bare, wet timber moves more and pulls at the joint. Paint up to the joint, not over the silicone.
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.
What else we do in Little Oakley
The process
The work is kept neat and contained to the joints we are treating. The job normally takes a morning for a couple of windows and a door, and we explain the cure time before we leave. For a village or hamlet like Little Oakley, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. 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.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Getting ready for the visit
- Clear the area around the work
- On commercial sites, let us know about site rules
- Mention if the joints have been sealed before

DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Signs you need window mastic in Little Oakley
Sun, frost and rain wear sealant out. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
It’s worth asking for a quote if you see:
- Black, perished sealant on frames
- Draughty joints inside around the window
- Whistling draughts around closed windows
- Gaps left after new windows were fitted
In the older streets around St Mary's House, the joint between an old wall and a newer frame is generally the first place rain gets in.

Frames and glazing around Little Oakley
Little Oakley is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Schools such as The Harwich School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. For landlords with property near Harwich International station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Little Oakley: your questions answered
Does living near the coast affect window mastic in Little Oakley?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Is Little Oakley within the area you cover?
Yes. Little Oakley is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Do you take out the old sealant first?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
What does window mastic cost?
Size, access and the old material all affect the cost. Call for a quick quote.
Do you guarantee window mastic?
Yes, for 12 months. A yearly look at the joints helps them last.
Will there be a smell?
That depends on the sealant. Some smell for a while, some hardly at all.
