Sand mastic in Finglesham, done properly
On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant, and we will talk through which suits your home. If you have old sand mastic that has cracked, crumbled or fallen out and gaps between timber frames and stone or brick, we can put it right, on period & listed homes, timber door frames and sash and case windows alike.
In a village or hamlet like Finglesham, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Landlords, agents and businesses in Finglesham
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Aftercare tips
A little care helps the new joints last. We recommend:
- Ask a joiner to look at soft timber first
- Leave the new mastic unpainted
- Don’t run silicone over sand mastic
- Take care around the mastic when scraping paint
Leave the new mastic unpainted, which is the traditional advice. Ask us before any decorating around it.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber and timber that stays wet can rot.
Frames and glazing around Finglesham
Finglesham is close to 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 older windows and doors, which can dry out and crack sooner where a building faces the weather. 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.
For landlords with property near Sandwich station, older sash windows in a rental need their mastic kept sound to keep the weather out. If you live in an older home near Church of St George, frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you look after a building such as Northbourne Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
Finglesham is about 2 miles north-west of Deal, in Kent. Jobs in Finglesham get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee.

When it is not the sealant
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Sash cords, weights and draught-proofing of the sashes
- Crumbling stone or brickwork round the window
- Putty and glazing repairs
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think before you book.

The process
When we arrive, we start by going over the job with you. Surfaces next to the work are protected before any work begins. Most jobs take anything from a few hours to a full day, depending on how many windows. In a small place like Finglesham, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
How to prepare
- Mention any tricky access
- Let us know about parking restrictions
- For indoor joints, keep the area dry beforehand if you can

Finglesham: your questions answered
Is Finglesham within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Is sand mastic in a coastal place like Finglesham any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
I rent my home. Can I book you?
Yes. Check with your landlord; we can send the quote to them too.
Is it OK to seal over old sealant?
No. We remove every bit of old sealant first, so the new sealant bonds properly.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little.
Which products do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
What’s sand mastic made of?
It’s the traditional filler for the joint round timber windows and doors. It combines sand with a linseed-oil-based binder.
Can you quote for more than one area?
Yes. Just list everything you need.
Why deal with it now?
Replacing sash windows is a big decision for a period home, and in listed buildings it may need consent. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Around Finglesham, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
