The process
We bring everything the job needs with us, so you do not need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. It normally takes a morning for a couple of windows and a door. Somewhere like Hulverstone 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 confirm safe access to each frame.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- 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
- Move anything stored near the joints
- Mention any tricky access

Advice
About our window mastic in Hulverstone
If you can feel air around a shut window, the gap is often at the frame. A new joint stops the air getting through and quietens the whistle on windy days. If the draught is through the window seals instead, we’ll tell you. If you have rain getting in at the frame or under the sill and cracked sealant at the sill ends, we can help.
Homes in small places like Hulverstone often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

Window mastic in Hulverstone: local notes
Hulverstone is within about 1 mile 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. Historic houses like Mottistone Manor (about 0.5 miles east) are a reminder that the area around Hulverstone has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Around Hulverstone, as everywhere, window mastic is only as good as the preparation behind it.

Common questions in Hulverstone
Will you come out to Hulverstone?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is window mastic in a coastal place like Hulverstone 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.
Can I paint over the new sealant?
Silicone generally won’t take paint. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
Does the work come with a guarantee?
Yes. Every job comes with our 12-month guarantee, and we’re fully insured.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.
Do you seal inside as well as outside?
Yes. Inside, the joint between frame and plaster is sealed neatly, using a paintable sealant if you want to decorate.
What we are called out for in Hulverstone
Mastic ages in the weather. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
Look out for these signs:
- Cracked sealant at the sill ends
- Rushed sealant from a window installation
- White mastic on grey or black frames
- Mastic that is falling out in pieces
In the older streets around St. Mary's Church, the joint between an old wall and a newer frame is generally the first place rain gets in.

- Whether all the old sealant comes out first

How the job changes by surface
uPVC windows
uPVC expands and contracts noticeably with temperature, so the joint needs a low-modulus sealant that stays flexible. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Composite doors
Draughts round the door leaf generally come from worn seals or adjustment, not the mastic. We seal the frame and let you know about anything else.

How to look after the new joints
So the new joints stay in good condition:
- Keep timber frames painted
- Make sure the drainage slots aren’t blocked
- Keep solvents and bleach off the sealant
- Walk round the house once a year and look at the joints
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early.
Look out for the warning signs: 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.
Why act early in Hulverstone
Running fresh sealant over the old joint is tempting, but new sealant can’t bond to old, crumbling mastic. It soon lifts and the leak carries on behind it. The old mastic has to come out. Where a wall is exposed, as many are in small places like Hulverstone, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
