High Park Corner Window Mastic
We cover High Park Corner for mastic around window and door frames, sills and patio doors. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- Gaps left after new windows were fitted
- Draughts coming in around windows and doors
- Draughty joints inside around the window
Should I try it myself first?
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

When it is not the sealant
We will always be straight with you, so here’s what sealant can’t fix:
- A door that needs adjusting, rehanging or new seals
- A sash or casement that will not close properly
- Rotten timber, which needs a joiner first
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly.
Surfaces we seal
- Timber windows & doors
- Composite doors
- Patio & French doors
- uPVC windows
- Window sills
- Aluminium frames
Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Make sure the drainage slots aren’t blocked
- Repaint timber before it’s bare
- Keep jet washers away from the mastic
- Paint up to the joint, not over it
Check the drainage slots in the frames aren’t blocked, so water can run away instead of sitting against the joint.
A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.
What happens on the day
The work is kept neat and contained to the joints we’re treating. Expect the work to take a few hours for a handful of frames, longer for a whole house, and we explain the cure time before we leave. Somewhere as small as High Park Corner, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- 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.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Mention if the joints have been sealed before
- For business premises, tell us about site rules or sign-in

High Park Corner homes and the weather
High Park Corner is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around window and door frames, especially on the side facing the sea. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as The Church of St Mary, the joint between an old wall and a newer frame is normally the first place rain gets in. For landlords with property near Wivenhoe station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
High Park Corner is about 4 miles south-east of Colchester, in Essex. Every kind of property in High Park Corner can book us for window mastic. Every job comes with our one-year guarantee. High Park Corner is one of 644 towns and villages in Essex we cover. There’s also a page for Chelmsford, about 22 miles away.

FAQs for High Park Corner
Do you work for landlords with property near Wivenhoe station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear price.
Does the coastal weather in High Park Corner affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are normally the first to need attention.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Do you work in High Park Corner?
We do. High Park Corner is part of the area we cover, and the service is the same as everywhere else.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in.
Can you match the sealant to my frames?
Usually, yes. Tell us the frame colour when you get in touch and we’ll match it as closely as we can.
Will new mastic stop draughts?
If the draught is coming in around the frame, yes. If it’s coming through the window seals, we will tell you.
How we quote for window mastic
Call for a quick quote. The main things that affect it are:
- Any mould that needs treating
- The product the joint needs
- How many rooms, windows or areas are involved
- How easy the joints are to reach
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.
What we need to know
Before you ask for a quote, have a think about:
- A few photos by email, if you can
- Any access issues, like height or stairs
- What the problem is, such as mould, gaps, leaks or cracking
- Where the property is
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, phone 0345 464 0079 or drop us an email.
Why deal with it now?
If you’re painting or rendering, reseal at the same time. A clean new bead makes new paint or render look finished. Where a wall is exposed, as many are in small places like High Park Corner, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
What you get with us
- We leave the area clean and tidy
- White, clear, grey or coloured to suit, where the product allows
- Anti-fungal silicone where joints get wet
- You choose the colour before work begins

When to call us in High Park Corner
Joint shape matters as much as the product. A thin smear across a wide gap has nothing to it, and a gap filled solid can’t flex. That’s what backing rod is for.
These are the problems we’re asked about most:
- Damp patches on the reveal after heavy rain
- Cracked sealant at the sill ends
- Gaps between the frame and the inside reveal
- Old mastic that has gone black or come away
For site and facilities teams at buildings such as Fingringhoe Church of England Voluntary Aided Primary School, the mastic around its windows and doors needs looking after like any other building’s.
