Window mastic for homes and businesses in Shorwell
Colour matters on a frame. White, brown, anthracite grey, black and clear sealants are all available, so the bead blends with the window rather than framing it. We are often asked to deal with mastic that has split away from the wall and cracked internal joints between frame and plaster, on aluminium frames, window sills and timber windows & doors.
Homes in small places like Shorwell 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.
All our work is covered by a one-year guarantee, wherever you are in the Isle of Wight.

Your questions about window mastic in Shorwell
Is window mastic in a coastal place like Shorwell any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Will you come out to Shorwell?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you have insurance?
Yes. We are fully insured.
Do I have to be there?
Access is agreed with you when the job is booked. Indoors, that normally means someone at home.
How long will my window job take?
The work takes most of a day for a typical house, less for a few frames. Access and the amount of old mastic make the biggest difference.
Do you work on first-floor windows?
Yes, where they can be reached safely. Tell us about access when you get in touch and we’ll plan for it.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Can you do the inside joint as well?
Yes. Plenty of draughts come through the inside joint as well as the outside, so it can be worth sealing both.
Leave it or put it right?
Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. Around Shorwell, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
We do not show prices on the website, because each job is priced on what it involves. For a quick quote, please call 0345 464 0079 or send us an email.

Common problems we fix in Shorwell
Joint shape matters as much as the product. A thin smear across a wide gap has nothing to it, while a joint packed solid cannot stretch. That is what backing rod is for.
Keep an eye out for any of the following:
- Hard, cracked sealant around windows
- Gaps left after new windows were fitted
- Draughty joints inside around the window
- Cold air getting in at the frame edge
Homes close to St. Peter's Church include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.
What your quote should include
- Is VAT in the price?
- How the joint is cleaned and prepared
- Who does the work, and how experienced they are
- Which sealant they’ll use, and why

Different surfaces, different methods
Patio & French doors
Heavy door frames can move more than windows. The sealant must cope with it without cracking.
uPVC windows
The frame is cleaned with a product that won’t harm the plastic, then the new bead is laid against the frame and the wall and tooled smooth.
Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
What we can’t put right
To be straight with you, there are a few things sealant won’t fix:
- A failed sealed unit that has misted up
- A sash or casement that won’t close properly
- A frame that has rotted at the joint
Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly before booking.

The process
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. It generally takes a morning for a couple of windows and a door. Somewhere like Shorwell needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- 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.
Preparing for the visit
- Clear the area around the work
- Tell us about any previous sealing or DIY attempts
- Plan for the work area to be out of bounds to pets and children

Frames and glazing around Shorwell
Shorwell is close to 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. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In and around Shorwell, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.
