Frames and glazing around Wellow
Wellow is close to 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. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Managing a site like Shalfleet Church of England Primary School? Then its window and door frames need their mastic kept sound, just like a home’s. If you live in an older home near Wellow Baptist Church, 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 Wellow
Every window and door frame has a gap around it, and mastic is what closes it. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. We work on aluminium frames, timber windows & doors and window sills, and the jobs we see most are draughts coming in around windows and doors and draughty joints inside around the window.
Mastic can only go onto a dry, clean joint, so window work in Wellow is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Every job is covered by our 12-month guarantee, wherever you are in the Isle of Wight.

For landlords and businesses
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can be quoted together.
DIY versus a professional finish
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How we quote for window mastic
Call for a quick quote. What matters most is:
- Whether old sealant or filler has to be cut out
- How many rooms, windows or areas are involved
- How easy the joints are to reach
- Any working-time requirements on site
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.
What to tell us for a quote
To help us quote quickly, please include:
- Photos by email, if that is easy
- If someone has resealed it before
- Where the job is, and your postcode
- Whether it’s a home or a business
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Do not use solvent cleaners on the joint
- Use gentle cleaners on frames and sealant
- Paint up to the joint, not over it
- Keep paint and stain on wooden frames in good order
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
When something else is needed
We will always be straight with you, so here’s what sealant can’t fix:
- Condensation trapped between the panes
- Penetrating damp from a failed cavity tray or render
- Soft or decayed wood in the frame
If you’re not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer.
Joints and surfaces we work on
- Timber windows & doors
- Patio & French doors
- Window sills
- Composite doors
- uPVC windows
- Aluminium frames
Different surfaces, different methods
Patio & French doors
Not every patio door leak is a mastic problem: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We check before we reseal.
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We will tell you which suits your home.
How the visit works
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours for a handful of frames, longer for a whole house. Somewhere like Wellow needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- 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.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Let us know about parking restrictions
- Tell us about any water getting in
