Sheldwich Window Mastic
Problem with your window and door frames in Sheldwich? We remove the old material, prepare the joints and seal them properly.
- Gaps where the sill meets the wall
- Whistling draughts around closed windows
- Rain getting in at the frame or under the sill
Window mastic in Sheldwich
Some gaps around frames are far deeper than they look. Packing it solid with sealant gives a joint that cannot flex, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. If you are dealing with draughty joints inside around the window and untidy mastic left by window fitters, we can help.
Outdoor sealant needs dry, clean surfaces, so work on frames around Sheldwich is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
Your job is guaranteed for a year, as with all our work.

What affects the quote in Sheldwich
Jobs vary more than people expect. The main factors:
- How easy the joints are to reach
- When we can work, for business premises
- The amount of work
- Mould in or behind the old joints
Combining jobs into one visit usually makes better use of the time than several visits. We’ll give you a clear quote for the lot.
What to tell us for a quote
To make quoting easier, let us know:
- How many joints, rooms or windows are involved
- A few photos by email, if you can
- The problem you’ve noticed
- Where the property is
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that is easy.
Why deal with it now?
Resealing frames is a short job: it takes anything from an hour or two to a full day, depending on how many frames there are. Leave it until water is coming in and you may need plastering and decorating as well. In a small place like Sheldwich, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What it costs depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts.

How the visit works
When we arrive, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before we start. The work generally takes most of a day for a typical house, less for a few frames. Somewhere as small as Sheldwich, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- 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.
How to prepare
- Tell us about any water getting in
- Mention any sign-in or site rules at work premises
- Clear items away from the joints we are working on

What the job involves on each surface
Aluminium frames
Aluminium needs a sealant that bonds to coated metal and we avoid acetoxy silicones, which can react with some metals. We use a neutral-cure product.
Composite doors
If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We will tell you if that is what we find.

Yes, we work for letting agents and landlords. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.
Can you do window mastic in Sheldwich?
Yes. Our work covers London and the South East, and Sheldwich is part of that. Just phone 0345 464 0079 or email us with a few details of the job.
Can new sealant go over the old?
No, it won’t last. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Can you do several jobs on one visit?
Yes. Several rooms, windows or areas can go on one quote.
Do the sealants smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint.
Do you have sealant for grey or black windows?
Yes. We can use white, brown, anthracite grey, black or clear.
Where is Mr Mastic based?
We are a Crawley-based firm. We work across South East England, London and Scotland.
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Signs you need window mastic in Sheldwich
A lot of older mastic was never designed to stay flexible. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.
These are the problems we’re asked about most:
- Gaps left after new windows were fitted
- Rain getting in at the frame or under the sill
- Cracked sealant at the sill ends
- Cold air getting in at the frame edge
If you live in an older home near Church of St James, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Sheldwich homes and the weather
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Belmont House and Gardens (about 1.6 miles west) nearby, there’s older building stock in the area around Sheldwich as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For site and facilities teams at buildings such as Sheldwich Primary School, the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Selling station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Walk round the house once a year and look at the joints
- Keep drainage slots and sill grooves clear
- Repaint timber before it’s bare
- Wipe condensation off the frames
Check the drainage slots in the frames aren’t blocked, so water can run away instead of sitting against the joint.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
