Leave it or put it right?
Draughts and leaks do not always mean new windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. Problems with the glass or gaskets are for a window company, and we will say so. In a small place like Mistley, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

How we handle window mastic in Mistley
Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the bead blends with the window rather than framing it. Common call-outs are for mastic that’s falling out in pieces and cracked sealant at the sill ends, on composite doors, timber windows & doors and uPVC windows.
Outdoor sealant needs dry, clean surfaces, so work on frames around Mistley is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
All of our work is guaranteed for twelve months, in Mistley and everywhere else we cover.

What affects the cost of window mastic
There’s no set price list. What we look at:
- How many areas need sealing
- The amount of work
- How much old sealant there is and how hard it is to remove
- How easy the joints are to reach
What it costs depends on how much there is to do, 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.

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
How the visit works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes most of a day for a typical house, less for a few frames and we leave things clean and tidy. Somewhere like Mistley needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely.
- The surfaces are cleaned and left dry.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Getting ready for the visit
- Plan for the work area to be out of bounds to pets and children
- On commercial sites, let us know about site rules
- For indoor joints, keep the area dry beforehand if you can

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Don’t paint over the silicone
- Wipe condensation off the frames
- Wash the frames with mild soapy water
- Keep jet washers away from the mastic
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.

How the job changes by surface
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.
Window sills
Stone and concrete sills have their own joints, including the one between the sill and the frame above. Those are sealed with a product suited to stone or concrete.
When it is not the sealant
We’ll always be straight with you, so here’s what new sealant won’t do:
- Damp problems in the wall away from the window
- A failed sealed unit that has misted up
- Draughts through the window seals rather than the frame
If you are not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer before you book.

What window mastic looks like in Mistley
Mistley is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. 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, 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 Site of Old St Mary's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you look after a building such as Mistley Norman Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s. If you let a flat or house near Mistley station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Do you work for landlords with property near Mistley station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.
Will you come out to Mistley?
Yes. Mistley is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Where do you work from?
Our base is Crawley. Our area covers South East England, London and Scotland.
Do you take out the old sealant first?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
Is it worth trying it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Are you an approved applicator?
Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply ring 0345 464 0079 or email us.
