Sand mastic in Wissenden
Silicone on a period window often looks wrong and is not always the right material. Sand mastic gives a finish that matches the age of the house, and we can replace one with the other. If you have mastic round period door frames that has failed and a silicone bead on a sash window that spoils the look, we can put it right, whatever the surface.
Mastic can only go onto a dry, clean joint, so window work in Wissenden is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

What affects the cost of sand mastic
There’s no set price list, because jobs vary so much. The quote depends on:
- Whether there’s mould to deal with
- How much old sealant there is and how hard it is to remove
- The size of the job
- Working hours on commercial sites
Doing several joints on one visit is usually more efficient than separate 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 ask for a quote, tell us:
- The rough size of the job
- A few photos by email, if you can
- If it’s domestic, commercial or a hotel
- How we’d reach the joints
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
Windows and doors in Wissenden
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. Historic houses like Godinton House (about 4.8 miles east) are a reminder that the area around Wissenden 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.
For landlords with property near Pluckley station, older sash windows in a rental need their mastic kept sound to keep the weather out. For site and facilities teams at buildings such as Bethersden Primary School, the mastic around its windows and doors needs looking after like any other building’s.

FAQs for Wissenden
Is Wissenden within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Pluckley station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.
Can you seal over the old sealant?
No, because it fails. The old sealant always comes out first.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Can I choose the sealant colour?
Yes. White, clear and grey are common, and other colours are available for many products, and we’ll agree it with you first.
Can I add another job to the visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will explain our choice.
How it works
We keep the work tidy and contained to the joints we are treating, so you can carry on as normal. Expect the work to take anything from a few hours to a full day, depending on how many windows, and we explain the cure time before we leave. For a village or hamlet like Wissenden, the journey is planned in advance: 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 look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
Preparing for the visit
- Tell us if parking is tricky
- Let us know about earlier repairs to the joints
- Where the joints are inside, avoid wetting them before we arrive

How the job changes by surface
Stone surrounds
We take care not to mark the stone while raking out the old mastic.
Brick reveals
Brick reveals round timber windows are often pointed with sand mastic. It gives a traditional finish.
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Find out about consent before window work on a listed home
- Keep modern sealant off the mastic
- Make sure water runs off the sill
- Do not paint over the new mastic
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber and timber that stays wet can rot.
When something else is needed
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Crumbling stone or brickwork round the window
- Cracked or broken glass
- Decisions on consent for listed homes
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly before booking.
