Sand mastic in Maplescombe, done properly
For a listed home or one in a conservation area, ask your local planning authority if consent is needed before window work. Sand mastic is often favoured as a like-for-like material. We work on tenement windows, brick reveals and timber door frames, and the jobs we see most are open joints round the window box and old sand mastic that has cracked, crumbled or fallen out.
Mastic can only go onto a dry, clean joint, so window work in Maplescombe is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

Frames and glazing around Maplescombe
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. Historic houses like Lullingstone Castle (about 1.9 miles west) are a reminder that the area around Maplescombe has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Lullingstone Castle, about 1.9 miles west, is one of the historic houses in the wider area around Maplescombe, and older homes nearby need a sealant that suits their walls.

Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

What happens on the day
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours per window, depending on the condition of the joints, and the area is left clean. In a small place like Maplescombe, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each surround and agreeing the joints to renew.
- 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.
- The mastic is finished to sit tidily against the stone or brick.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- On commercial sites, let us know about site rules
- Mention if the joints have been sealed before

Looking after it afterwards
To keep the joints looking good and working properly:
- Check with your local planning authority if your home is listed
- Take care around the mastic when scraping paint
- Make sure water runs off the sill
- Do not run silicone over sand mastic
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look before trying a quick fix.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.

Should I use sand mastic or silicone?
We will talk it through with you. Period homes often look best with sand mastic and newer frames suit modern sealant.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We will tell you what we’re using and why.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Is consent needed for window work on a listed home?
It’s best to ask your local planning authority first. Sand mastic is often favoured as like for like but the decision is theirs.
What’s sand mastic made of?
A traditional pointing material made from sand and a linseed-oil-based binder, used between timber frames and stone or brick.
Work for landlords, hotels and businesses

How we quote for sand mastic
We quote each job individually. This is what makes a difference:
- Which sealant suits the joint
- Whether there’s mould to deal with
- The number and length of the joints
- How easy the joints are to reach
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, call 0345 464 0079 or email us and we’ll give you an honest view and a quote.
Asking for a quote
When you call or email, these details help:
- If someone has resealed it before
- Where the job is, and your postcode
- The type of property
- The rough size of the job
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.
When to call us in Maplescombe
Shallow joints are a common cause. A thin layer does not hold well, which is why we pack deep voids first and get the depth right.
The problems people generally mention when they call include:
- Crumbling sand mastic round a window
- Draughts and rain around sash boxes
- Gaps between timber frames and stone or brick
- Mastic round period door frames that has failed
If you let a flat or house near Eynsford station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

- How long to leave it before use
Leave it or put it right?
Cement-based fillers and modern sealants don’t always suit a period surround. Sand mastic matches what was there, which can matter on listed and conservation-area homes. In a small place like Maplescombe, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost depends on the size of the job, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.
