Window & door mastic in East Cowes, Isle of Wight
Window and door frames in East Cowes need attention? We remove the old material, prepare the joints and seal them properly, with a one-year guarantee.
- Cracked internal joints between frame and plaster
- A bead that does not match the frame
- Mastic that is falling out in pieces
Window mastic in East Cowes
Most frames have an outside joint and an inside one. Outside, the mastic keeps rain out; the internal joint closes the gap to the plaster and stops draughts. Either or both can be done. We work on timber windows & doors, uPVC windows and window sills, and people most often call us about draughty joints inside around the window and water coming in at the bottom corners of a door.
Around East Cowes, conservatories, garden rooms and patio doors are often part of the house. Those joints need the same attention as the main windows, and any older timber or sash windows need a sealant that suits them.
You are covered for a year from the day we finish. If anything isn’t right with it, phone 0345 464 0079 or send us an email.

Signs you need window mastic in East Cowes
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.
Keep an eye out for any of the following:
- Draughty joints inside around the window
- Sealant in the wrong colour for the frame
- Gaps left after new windows were fitted
- Draughts coming in around windows and doors
Homes close to St James's Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

- 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.
Helping us quote
Photos help, but a description is a good start. Try to tell us:
- Any access issues, like height or stairs
- Any previous sealing or DIY work
- Pictures of the joints, sent by email

Windows and doors in East Cowes
East Cowes is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. 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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For site and facilities teams at buildings such as Isle of Wight Studio School, the mastic around its windows and doors needs looking after like any other building’s.

The process
There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for a handful of frames, longer for a whole house for a typical job. In a smaller place like East Cowes, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Mention any sign-in or site rules at work premises
- Keep pets and children clear of the area while we work

Advice
For landlords and businesses
If you manage several properties in or around East Cowes, several properties can be quoted together. Just tell us the addresses and what each one needs, and photos by email help.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.
Surface by surface
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the threshold joint takes a lot of water. We prepare and reseal every joint, backing the deep ones.
uPVC windows
We clean the frame edge carefully so the plastic is not marked, then the sealant goes in between frame and wall and tooled smooth.
Common questions in East Cowes
Is window mastic in a coastal place like East Cowes any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Do you cover smaller places like East Cowes?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Can landlords and businesses book you?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels.
Do you work on first-floor windows?
Yes, if safe access is possible. Higher or awkward frames may need extra access, and we will confirm what’s needed.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
I rent my home. Can I book you?
Of course. Ask your landlord first, and we can send them the quote if that helps.
Why deal with it now?
Choosing the product is half the job. Interior caulk and bathroom silicone are not made for exterior frame joints. An exterior, low-modulus sealant stays flexible in sun and frost. Homes in smaller places like East Cowes can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or drop us an email.
