About our window mastic in Beltinge
Around Beltinge we seal all kinds of frames: uPVC, aluminium, timber and composite, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. Typical jobs include gaps where the sill meets the wall and damp patches on the reveal after heavy rain, across uPVC windows, window sills and patio & French doors.
Houses in smaller places like Beltinge can stand more in the open than those in a built-up town. That is hard on the mastic around frames and sills.
You are covered for a year from the day we finish. If anything isn’t right with it, phone 0345 464 0079 or email us.

Common questions in Beltinge
Can you help a landlord with a rental near Herne Bay station?
Yes. We work for landlords and agents as well as homeowners. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Will you come out to Beltinge?
Yes. Beltinge is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
What do you need from me for a quote?
A short description and the location, with pictures by email if possible. If we need more, we’ll ask.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Can you quote for more than one area?
Yes. Several rooms, windows or areas can go on one quote.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.

Different surfaces, different methods
Window sills
Every drop off the glass ends up on the sill, so the joints at each end and underneath matter. Each is cleaned out and resealed.
Composite doors
Composite doors are normally hung in an uPVC-type frame, so its perimeter joint is sealed much like a window. We match the colour to the frame.
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Beltinge homes and the weather
Beltinge is close to 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. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you let a flat or house near Herne Bay station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. In the older streets around Church of St Bartholomew, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Why deal with it now?
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, using a product chosen for the frame and wall. Homes in smaller places like Beltinge can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please call 0345 464 0079 or email us.

When to call us in Beltinge
Mastic ages in the weather. Sunlight dries the surface out, until it loses its stretch and starts to crack.
If you can see any of these, it’s time to have the joints looked at:
- Cold air getting in at the frame edge
- Cracked internal joints between frame and plaster
- Cracked or shrunken mastic around the frame
- Water coming in at the bottom corners of a door
If you look after a building such as Reculver Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s.
Before you book anyone
- How hidden problems are handled
- When the joint can take water or movement
- Which sealant they’ll use, and why
- The length of the guarantee
What happens on the day
Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a handful of frames, longer for a whole house. A visit to Beltinge is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- 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.
- We tool each bead neatly and check every joint is closed.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Where the joints are inside, avoid wetting them before we arrive
- Tell us if parking is tricky
