Common questions in West Blatchington
Does living near the coast affect sand mastic in West Blatchington?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Do you work for landlords with property near Aldrington station?
Yes. We work for landlords and agents as well as homeowners. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
How long does the job take?
A typical job takes a few hours per window, depending on the condition of the joints, including the preparation. Your quote will say how long we expect yours to take.
Do you hold any approvals?
Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
How long does sand mastic take to go off?
Not right away. The skin forms first, and the full set comes later, and we’ll tell you what to expect.
What’s sand mastic made of?
Sand plus a binder based on linseed oil. It’s built up in the joint by hand and shaped to suit the surround.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
What information do you need?
Let us know what needs doing and where. If we need more, we will ask.
Sand mastic in West Blatchington
For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. If you’re dealing with gaps where the frame meets the masonry and mastic worn away on windows facing the weather, we can put it right.
Houses in smaller places like West Blatchington can stand more in the open than those in a built-up town. The mastic around frames on those walls tends to age faster.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Signs you need sand mastic in West Blatchington
Water gets into small cracks in the mastic and pushes it out. Exposed elevations generally fail first.
Look out for any of the following:
- Silicone on a period window that looks wrong
- Weathered mastic on the most exposed windows
- Cracked mastic round a front door frame
- Old cement repairs round a window that have failed
In the older streets around St Peter's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Questions to ask before booking
- Whether VAT is included
- How the colour is chosen
- Whether they’re fully insured
- What product goes in the joint
Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Leave it or put it right?
A silicone bead can be quicker, but on period stone or brick it often looks out of place. Sand mastic is the traditional material and blends with the stone or brick. In a smaller place like West Blatchington, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Make sure water runs off the sill
- Have rotten timber repaired before new mastic goes in
- Do not run silicone over sand mastic
- Inspect the joints round the windows every year or so
Avoid painting over the new mastic, as traditional guidance advises. If you’re redecorating, ask us first.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber, which can lead to rot.
What affects the cost of sand mastic
Your quote is based on your job. We take into account:
- Access and height
- Any mould that needs treating
- Which sealant suits the joint
- Whether old sealant or filler has to be cut out
Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.
Helping us quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Where the job is, and your postcode
- The type of property
- Whether it has been sealed before
- What’s wrong with the joints now

The process
There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes anything from a few hours to a full day, depending on how many windows, including the tidy-up. For a job in West Blatchington, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- For business premises, tell us about site rules or sign-in
- Plan for the work area to be out of bounds to pets and children
How to get a quote
We quote each job on its own. Simply ring 0345 464 0079 or drop us an email and describe the job, and pictures are welcome.

Sand mastic in West Blatchington: local notes
West Blatchington 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 is hard on the mastic around older windows and doors, especially on the side facing the sea. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you look after a building such as Aldrington CofE Primary School, larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Aldrington station, cracked sand mastic around sash windows lets in the draughts tenants complain about.
