Window mastic for homes and businesses in Shorne
Over two decades of sealing frames has taught us which products suit which walls. We’re fully insured ARBOMaster approved applicators, and we give a one-year guarantee on the work. Typical jobs include gaps where the sill meets the wall and old mastic that has gone black or come away, across uPVC windows, composite doors and window sills.
Mastic can only go onto a dry, clean joint, so window work in Shorne is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

What the job involves on each 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.
Composite doors
If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We seal the frame and let you know about anything else.
Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Look round the frames every year or so
- Keep timber frames painted
- Clean frames with a soft cloth and soapy water
- Don’t use solvent cleaners on the joint
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just phone 0345 464 0079 or email us.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.
Frames and glazing around Shorne
Shorne is within about 3 miles 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. Historic houses like Cobham College (about 2.3 miles south-west) are a reminder that the area around Shorne has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Rented homes near Higham station change hands often, and 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 Peter and St Paul, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What affects the quote in Shorne
Jobs vary more than people expect. The main factors:
- Whether the work is at height
- The number and length of the joints
- Whether there’s mould to deal with
- How many areas need sealing
Doing several joints on one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.
What we need to know
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- The type of property
- The problem you’ve noticed
- Photos by email, if that is easy
- The rough size of the job
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 email photos if that’s easy.
What we do, step by step
On the day, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work begins. Most jobs take anything from an hour or two to a full day, depending on how many frames there are. In a small place like Shorne, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- 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
- Tell us about access, such as stairs, a lift or high-level joints
- Keep children and pets away from the work area
- For business premises, tell us about site rules or sign-in

Advice
Shorne: your questions answered
Does the coastal weather in Shorne affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Do you work for landlords with property near Higham station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.
Can I do it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Can you do upstairs windows?
Yes, where they can be reached safely. Tell us about access when you get in touch so we can plan the job.
Can new window sealant be painted?
Not if it’s silicone. Tell us your decorating plans and we will pick a sealant to suit.
Do you have sealant for grey or black windows?
Yes. Anthracite grey, black, brown and white cover most frames, with clear as an option.
Do you work in Shorne?
Yes. We work in Shorne. For a quote, call 0345 464 0079 or drop us an email.
How long does it take to reseal the windows on a house?
It depends on access, the old mastic and the size of the frames. We’ll tell you how long your job needs when we quote.
What happens if it’s left?
A quick bead over the top of old mastic looks like an easy fix, but it will not grip old, dirty sealant. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. Around Shorne, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Do you need window mastic in Shorne?
Sills take more water than any other part of a window, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
Keep an eye out for these signs:
- Draughts coming in around windows and doors
- Water coming in at the bottom corners of a door
- Cracked internal joints between frame and plaster
- Untidy mastic left by window fitters
If you look after a building such as Shorne Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s.
