About our window mastic in Chidham
Some gaps around frames are far deeper than they look. Packing it solid with sealant gives a joint that cannot flex, so deep gaps get backing rod first. That way the new bead bonds to the frame and the wall only. If you’re dealing with a bead that doesn’t match the frame and cracked internal joints between frame and plaster, we can help, on patio & French doors, window sills and aluminium frames alike.
Around Chidham, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
All our work is covered by our 12-month guarantee, wherever you are in West Sussex.

Frames and glazing around Chidham
Chidham is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around window and door frames, especially on the side facing the sea. Historic houses like Warblington Castle (about 4.1 miles west) are a reminder that the area around Chidham has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you let a flat or house near Nutbourne station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. If you live in an older home near The Parish Church of St Mary, the joint between an old wall and a newer frame is generally the first place rain gets in.

What else we do in Chidham
Surface by surface
Timber windows & doors
Soft or rotten wood cannot be sealed successfully. If we find rot, we’ll tell you before going ahead, as that’s a job for a joiner.
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. It comes out, deep gaps get backing rod and the joint is resealed.
Common questions in Chidham
Do you cover smaller places like Chidham?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Does living near the coast affect window mastic in Chidham?
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 usually the first to need attention.
What information do you need?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Will resealing my frames help with draughts?
If the draught is coming in around the frame, yes. If it’s through the window’s own seals or a hinge, that’s a different fix, and we will say so.
Is the work guaranteed?
Yes. Each job is covered for 12 months.
Can tenants book the work?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we’re done.
Can you do upstairs windows?
Generally, yes. We plan safe access before the job, so mention the height and anything in the way.
When to call us in Chidham
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.
Keep an eye out for any of the following:
- A bead that does not match the frame
- Untidy mastic left by window fitters
- Rain getting in at the frame or under the sill
- Draughty joints inside around the window
Schools such as Chidham Parochial Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Quotes for window mastic in Chidham
Your quote is based on your job. We look at:
- Access and height
- How many areas need sealing
- Which sealant suits the joint
- Mould in or behind the old joints
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or send us an email.
What to tell us for a quote
To make quoting easier, please include:
- The problem you’ve noticed
- Where the property is
- Whether it’s a home or a business
- How many joints, rooms or windows are involved
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Keep drainage slots and sill grooves clear
- Repaint timber before it’s bare
- Wipe condensation off the frames
- Look round the frames every year or so
Silicone cannot usually be painted, so mention any painting plans before work begins. We can use a paintable sealant where that matters.
Look out for the warning signs: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.
What happens on the day
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the work takes anything from an hour or two to a full day, depending on how many frames there are for a typical job. Somewhere as small as Chidham, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Before we arrive
- Clear items away from the joints we’re working on
- Let us know about stairs, lifts or work at height
- Plan for the work area to be out of bounds to pets and children

DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
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 fails, we can still redo it.
