Farthingloe Sand Mastic
We cover Farthingloe for traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Old cement repairs round a window that have failed
- Mastic dropping out of the joint
- Modern sealant on a period surround
Sand mastic for homes and businesses in Farthingloe
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s made from sand and a linseed-oil-based binder, applied by hand. On older homes, it suits the building far better than silicone. Common call-outs are for gaps where the frame meets the masonry and draughts and rain around sash boxes, on brick reveals, timber door frames and stone surrounds.
Somewhere as small as Farthingloe, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Big or small, you get the same one-year guarantee.

- Putty and glazing repairs
If in doubt, ring 0345 464 0079 or email us and we will say what we think.

DIY sealant or a professional job?
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.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
What affects the quote in Farthingloe
The quote reflects the job in front of us. We look at:
- How much old sealant there is and how hard it is to remove
- Access and height
- The number and length of the joints
- The product the joint needs
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.
Helping us quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- The type of property
- Access, such as stairs, a lift or height
- Pictures of the joints, sent by email
- The rough size of the job
There’s no standard price list, as no two jobs are quite the same. Instead, we send you a clear quote for your job. To get started, call 0345 464 0079 or send us an email.
Farthingloe homes and the weather
Farthingloe is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Managing a site like Aycliffe Community Primary School? Then its window and door frames need their mastic kept sound, just like a home’s. Letting a property close to Dover Priory station? Then any sash windows need sound mastic to keep draughts and rain out.

Farthingloe: your questions answered
I let a flat near Dover Priory station. Can you help?
Yes. We work for landlords and letting agents as well as householders. You can call 0345 464 0079 or email us with the details for a clear quote.
Will you come out to Farthingloe?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
How long does sand mastic take to harden?
It takes a while. It skins first and hardens fully later, and we’ll tell you what to expect.
Do you guarantee sand mastic work?
There’s a 12-month guarantee on every job, sand mastic included.
Will there be a smell?
Possibly a little. It fades as the sealant cures.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
For landlords and businesses
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
We also work for property managers and facilities teams. We can quote a run of properties together, and we are fully insured.
How it works
Every visit runs the same way: we check the joints, protect the area around them, do the work and tidy away. It generally takes anything from a few hours to a full day, depending on how many windows. In a small place like Farthingloe, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check the window surrounds and agree which joints need renewing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic isn’t too thick.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Plan for the work area to be out of bounds to pets and children
- On commercial sites, let us know about site rules

What we’re called out for in Farthingloe
Rain on the window surround works into any crack and pushes it out. Exposed elevations normally fail first.
Common reasons people contact us include:
- A silicone bead on a sash window that spoils the look
- Old cement repairs round a window that have failed
- Mastic that needs renewing before redecorating
- Open joints round the window box
Homes close to Aycliffe Church Centre include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Questions to ask before booking
- Who turns up on the day
- How the surfaces are prepared before sealing
- When the joint can take water or movement
- Whether VAT is included
Different surfaces, different methods
Period and listed homes
Sand mastic is the like-for-like choice for many period homes. If your home is listed, ask your local planning authority about consent.
Timber door frames
Doors face weather and wear, so their mastic can fail sooner. It’s renewed by hand.
