What sand mastic looks like in Sarisbury Green
Sarisbury Green is within about 2 miles of 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. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For landlords with property near Swanwick station, older sash windows in a rental need their mastic kept sound to keep the weather out. If you look after a building such as Sarisbury Infant School, its window and door frames need their mastic kept sound, just like a home’s.

How we handle sand mastic in Sarisbury Green
We renew sand mastic around sash windows and doors in stone and brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. If you are dealing with mastic dropping out of the joint and weathered mastic on the most exposed windows, we can put it right, on sash and case windows, stone surrounds and tenement windows alike.
Homes around Sarisbury Green range from older properties to newer houses, and their windows range just as widely. Each frame material needs the right sealant against the right wall.
Every job comes with our 12-month guarantee.

What affects the cost of sand mastic
Call for a quick quote. What matters most is:
- Access and height
- When we can work, for business premises
- How many rooms, windows or areas are involved
- The old material and how stubborn it is
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.
Asking for a quote
There’s no need for technical detail. Just tell us:
- The address or postcode of the job
- How we’d reach the joints
- What the problem is, such as mould, gaps, leaks or cracking
- The rough size of the job
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, ring 0345 464 0079 or drop us an email.
Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Leave the new mastic unpainted
- Ask the planning authority about consent for listed or conservation-area homes
- Have rotten timber repaired before new mastic goes in
- 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. Once it fails, water can sit against the timber, which can lead to rot.
Leave it or put it right?
New mastic over crumbling mastic won’t hold. We remove the loose material first so the new work lasts. Around Sarisbury Green, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
Doing several joints on one visit is usually more efficient than separate visits. We’ll give you a clear price for the lot.

Questions from Sarisbury Green
Can you help a landlord with a rental near Swanwick station?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. You can call 0345 464 0079 or email us with the details for a clear quote.
Will you come out to Sarisbury Green?
Yes. Sarisbury Green is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you match the sealant colour?
In most cases you can choose. We will tell you which colours the right product comes in and agree one before work begins.
Will the old sealant be removed?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
What exactly is sand mastic?
It’s sand mixed with a linseed-oil-based binder, used between timber frames and stone or brick.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
How long does sand mastic take to go off?
It takes a while. The skin forms first, and the full set comes later and we will give you an idea for your job.
Different surfaces, different methods
Brick reveals
An open joint at a brick reveal lets weather in. Renewing the mastic closes it.
Timber door frames
Period doors in stone or brick openings are often pointed with sand mastic. We renew it the same way as on windows.
Should I try it myself first?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
What we are called out for in Sarisbury Green
Shallow joints are a common cause. A thin layer doesn’t hold well, which is why we pack deep voids first and get the depth right.
Most people get in touch after spotting something like this:
- Wind and rain getting in round a sash window
- Failed mastic on an exposed elevation
- Open joints round the window box
- Cracked mastic round a front door frame
If you live in an older home near Church of St Paul, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Questions to ask before you book
- Are they insured?
- What happens if they find a problem under the old sealant
- Is the old sealant removed completely?
- Whether you can choose the colour
How the visit works
We bring everything the job needs with us. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours for a single window, longer for several. In a smaller place like Sarisbury Green, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
How to prepare
- For business premises, tell us about site rules or sign-in
- Keep children and pets away from the work area
- Where the joints are inside, avoid wetting them before we arrive
