What the job involves on each surface
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. It comes out, deep gaps get backing rod and the joint is resealed.
Composite doors
Composite doors are normally hung in an uPVC-type frame, so its perimeter joint is sealed much like a window. The bead is colour-matched to the frame.
Window mastic in Clatterford
Colour matters on a frame. White, brown, anthracite grey, black and clear sealants are all available, so the line suits the frame instead of standing out. We’re often asked to deal with gaps between the frame and the inside reveal and rain getting in at the frame or under the sill, on window sills, composite doors and patio & French doors.
Homes in small places like Clatterford often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
Whatever the size of the job, you get the same 12-month guarantee.

Where do you work from?

What do you put in the joint?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Can I paint over the new sealant?
Not usually, if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.
Will there be a smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Look round the frames every year or so
- Keep timber frames painted
- Keep solvents and bleach off the sealant
- Paint up to the joint, not over it
Silicone cannot generally be painted, so if you are planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
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.
Window mastic in Clatterford: local notes
The South East is one of the drier parts 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 Carisbrooke Castle (about 0.3 miles east) nearby, there’s older building stock in the area around Clatterford as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
If you look after a building such as St Thomas of Canterbury Catholic Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
Clatterford is about 1 mile south-west of Newport, in the Isle of Wight. We carry out window mastic for homes and businesses in Clatterford and the surrounding area. 125 places in the Isle of Wight are on our list, from the larger towns to small villages. There’s also a page for Portsmouth, about 13 miles away.
We cover every part of PO30 for window mastic. You will find streets such as Down Lane, Castle Lane and High Street. Nearby, we also carry out window mastic in Carisbrooke (1 mile north), Plaish (1 mile south-west), Gunville (1 mile north), Bowcombe (1 mile south-west) and Gatcombe (2 miles south). We also work in nearby towns such as Ryde (7 miles east), Cowes (5 miles north), Sandown (7 miles east), Shanklin (7 miles south-east), Ventnor (8 miles south-east) and East Cowes (5 miles north). If you are somewhere remote, a little more planning is needed.
What’s near Clatterford
We work in homes and buildings around The Waverley pub, Island Innovation VI Form Campus and Christ The King College. Nearby you will also find Whitecroft Hospital (1.3 miles south-east) and Carisbrooke Castle (under half a mile east). Not far away are Brighstone Down and Briddlesford Nature Reserve.
DIY versus a professional finish
If you’re set on DIY, put the effort into 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.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Why deal with it now?
If you’re painting or rendering, reseal at the same time. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. Around Clatterford, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Combining jobs into one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll give you a clear price for the lot.

What we are called out for in Clatterford
On timber frames, paint and putty build up around the joint. Old mastic gets painted over and cracks under the paint, and the wood moves with damp as well as heat.
People generally contact us when they notice one of these:
- Untidy mastic left by window fitters
- White mastic on grey or black frames
- Gaps where the sill meets the wall
- Damp patches on the reveal after heavy rain
Homes close to Church of St. Nicholas in Castro include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What happens on the day
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it generally takes most of a day for a typical house, less for a few frames. Somewhere as small as Clatterford, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- Mention if the joints have been sealed before
- On commercial sites, let us know about site rules
- Tell us about access, such as stairs, a lift or high-level joints

We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:
- Penetrating damp from a failed cavity tray or render
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Soft or decayed wood in the frame
