Window & door mastic in Newbridge, Isle of Wight
We cover Newbridge for mastic around window and door frames, sills and patio doors. Old material cut out, joints cleaned and sealed neatly.
- Water coming in at the bottom corners of a door
- Hard, cracked sealant around windows
- Draughty joints inside around the window
Do you need window mastic in Newbridge?
Sills take more water than any other part of a window, so the sill ends and the joint below the frame are common leak points. When that sealant fails, water gets into the wall or under the frame.
These are the problems we’re asked about most:
- Leaking joints at the ends of sills
- Hard, cracked sealant around windows
- Damp patches on the reveal after heavy rain
- Cold air getting in at the frame edge
Homes close to Church of St. Michael the Archangel include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

How we handle window mastic in Newbridge
A cold draught around a closed window often comes from the frame edge. Resealing that joint can make a room feel noticeably less draughty. Where the air is getting in through the window itself, we’ll say so. We work on window sills, timber windows & doors and aluminium frames, and people most often call us about mastic that’s falling out in pieces and gaps between the frame and the inside reveal.
Somewhere as small as Newbridge, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
We stand behind the work with a one-year guarantee, so you’re not left on your own once the job is done.

Windows and doors in Newbridge
Newbridge is within about 3 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around window and door frames, especially on the side facing the sea. Historic houses like Swainston Manor (about 1.8 miles east) are a reminder that the area around Newbridge has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Schools such as Shalfleet Church of England Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

What happens if it’s left?
Working on frames from a ladder with a sealant gun isn’t easy, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, using a product chosen for the frame and wall. Older cottages and farmhouses around Newbridge can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.

DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
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.
How it works
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours for a handful of frames, longer for a whole house. Somewhere like Newbridge needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Before we arrive
- Let us know about stairs, lifts or work at height
- Mention any leaks or damp you’ve noticed
- For business premises, tell us about site rules or sign-in

Advice
Looking after it afterwards
After the cure time, these simple habits help:
- Ventilate rooms so frames don’t stay wet inside
- Avoid blasting the frames with a pressure washer
- Wash the frames with mild soapy water
- Walk round the house once a year and look at the joints
Silicone can’t generally be painted, so if you’re planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
Leaks generally show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
Common questions in Newbridge
Is window mastic in a coastal place like Newbridge any different?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Do you cover Newbridge for window mastic?
Yes, Newbridge is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or send us an email and let us know what needs doing, and we’ll give you a clear price.
I’m a tenant. Can you help?
Yes. Check with your landlord; we can send the quote to them too.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Do you have sealant for grey or black windows?
Yes. White, brown, anthracite grey, black and clear sealants are all available, so the joint suits the frame.
Can you do the inside joint as well?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We can do either or both.
Can new window sealant be painted?
Not usually, if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
