Window & door mastic in Newchurch, Isle of Wight
We cover Newchurch for mastic around window and door frames, sills and patio doors. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Draughty joints inside around the window
- Cold air getting in at the frame edge
- A bead that does not match the frame
Window mastic in Newchurch
A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. We work on patio & French doors, uPVC windows and window sills, and the jobs we see most are a bead that doesn’t match the frame and leaking joints at the ends of sills.
Outdoor sealant needs dry, clean surfaces, so work on frames around Newchurch is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
The work is covered for a year after we finish. If anything isn’t right with it, phone 0345 464 0079 or email us.

What we do, step by step
When we arrive, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before work begins. Most jobs take a few hours for a few frames, or a day or more for a whole house. In a small place like Newchurch, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit

- Let us know about parking restrictions

Related advice
DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
How the job changes by surface
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A tidy bead in anthracite grey, black or a matching colour suits the frame.
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. We will point out any rot we find, as that is a job for a joiner.
Signs you need window mastic in Newchurch
Mastic ages in the weather. UV light hardens the outside of the bead, until it loses its stretch and starts to crack.
Signs it’s time to call us include:
- Water coming in at the bottom corners of a door
- A bead that does not match the frame
- Old mastic that has gone black or come away
- Cracked internal joints between frame and plaster
Homes close to All Saints' Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Window mastic in Newchurch: local notes
Newchurch 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. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For landlords with property near Sandown station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Schools such as Newchurch Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Newchurch: your questions answered
Do you work for landlords with property near Sandown station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just call 0345 464 0079 or email us with the address and what needs doing, and we’ll send you a clear quote.
Does living near the coast affect window mastic in Newchurch?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done.
Do you work on first-floor windows?
Yes, if safe access is possible. For high or awkward windows, we’ll tell you what access is needed.
Can you work on commercial sites?
Yes, regularly. Larger jobs can be planned room by room or area by area.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Can resealing stop a draught around my window?
It will if the frame joint is the problem. We check where the draught is before any work starts.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.

Looking after it afterwards
After the cure time, these simple habits help:
- Clear any debris from frame drain holes
- Use gentle cleaners on frames and sealant
- Keep jet washers away from the mastic
- Ventilate rooms so frames do not stay wet inside
Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.
What happens if it’s left?
A quick bead over the top of old mastic looks like an easy fix, but it will not grip old, dirty sealant. It peels before long, and water still gets in behind. The old mastic has to come out. In a small place like Newchurch, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
