About our sand mastic in Guestling Green
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It suits period and listed homes where a modern sealant bead would stand out. If you have mastic dropping out of the joint and cracked mastic round a front door frame, we can help, on sash and case windows, tenement windows and timber door frames alike.
Somewhere as small as Guestling Green, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
We stand behind the work with a one-year guarantee, so you are covered after we’ve gone.

Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Inspect the joints round the windows every year or so
- Don’t run silicone over sand mastic
- Check with your local planning authority if your home is listed
- Avoid heavy scraping on the mastic joint
Leave the new mastic unpainted, as traditional guidance advises. Ask us before any decorating around it.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
Windows and doors in Guestling Green
Guestling Green is close to 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 older windows and doors, especially on the side facing the sea. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Three Oaks station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about. Managing a site like Guestling Bradshaw Church of England Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as St Laurence's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Questions from Guestling Green
Is Guestling Green 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.
Does living near the coast affect sand mastic in Guestling Green?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
How do I get a quote for sand mastic in Guestling Green?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we will talk you through it.
Which is right for my windows, sand mastic or modern sealant?
We will talk it through with you. Period homes often look best with sand mastic and newer frames suit modern sealant.
Do you offer different sealant colours?
Normally, yes. Sealants come in white, clear, grey and other colours for many products, and we agree the colour with you before any work starts.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
Do you work for letting agents?
Yes. As well as householders, we work for landlords, agents, businesses and hotels across East Sussex.
Are you fully insured?
Yes. We are fully insured, and we can confirm the details when we quote.
Why deal with it now?
New mastic over crumbling mastic won’t hold. Raking out and preparing the joint gives it a sound base so the new mastic stays put. Older cottages and farmhouses around Guestling Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
Why us?
- Fully insured
- Trusted Arbo and Everbuild sealants

How the visit works
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 Guestling Green, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we look at the surrounds with you and agree what needs doing.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic is not 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.
Getting ready for the visit
- Keep children and pets away from the work area
- Tell us about any water getting in
- Mention any sign-in or site rules at work premises

Your quote is based on your job. We take into account:
- The product the joint needs
- The amount of work
- The old material and how stubborn it is

What to tell us for a quote
Before you ask for a quote, have a think about:
- Access, such as stairs, a lift or height
- The rough size of the job
- If it’s domestic, commercial or a hotel
