How we handle sand mastic in Broom Street
Sand mastic suits most period window surrounds. Newer frames usually get a flexible sealant instead and we will explain which is best for yours. Common call-outs are for open joints round the window box and draughty sash windows at the surround, on timber door frames, tenement windows and period & listed homes.
Outdoor sealant needs dry, clean surfaces, so work on frames around Broom Street is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

Your questions about sand mastic in Broom Street
I let a flat near Faversham station. Can you help?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear price.
Is Broom Street within the area you cover?
Yes. Broom Street is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
How long will you be here?
Typically it takes anything from a few hours to a full day, depending on how many windows. Larger jobs naturally take longer.
How long does sand mastic take to go off?
A skin forms quite soon, but full hardening takes longer. We’ll tell you what to expect for your job.
What is sand mastic?
Sand mastic is a traditional material for pointing round windows and doors. It combines sand with a linseed-oil-based binder.
Which is right for my windows, sand mastic or modern sealant?
Sand mastic normally suits period timber windows best. Modern frames normally suit a flexible sealant, and we’ll explain why.
How do I get a quote for sand mastic in Broom Street?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before we start.
Can you do several jobs on one visit?
Yes. Several rooms, windows or areas can go on one quote.
Signs you need sand mastic in Broom Street
Previous repairs in cement or silicone often trap water or crack away. They do not suit the joint and we normally remove them.
It’s worth asking for a quote if you see:
- Old sand mastic that has cracked, crumbled or fallen out
- Gaps round a timber door in stone or brick
- Draughts and rain around sash boxes
- Open joints round the window box
If you look after a building such as Graveney Primary School, its window and door frames need their mastic kept sound, just like a home’s.
Questions to ask before booking

Sand mastic in Broom Street: local notes
Broom Street is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For landlords with property near Faversham station, cracked sand mastic around sash windows lets in the draughts tenants complain about. In the older streets around Church of All Saints, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

How the visit works
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours for a single window, longer for several. In a small place like Broom Street, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Tell us if parking is tricky
- Mention any leaks or damp you’ve noticed
Getting a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email pictures if that’s easy.
Advice
How we quote for sand mastic
The quote reflects the job in front of us. We take into account:
- Working hours on commercial sites
- Mould in or behind the old joints
- The old material and how stubborn it is
- How easy the joints are to reach
We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or email us.
Asking for a quote
What to tell us when you ask for a quote:
- Where the job is, and your postcode
- Any previous sealing or DIY work
- The rough size of the job
- Pictures of the joints, sent by email
Need a quote? Please call 0345 464 0079 or send us an email with a few details. We will explain what we’d do and give you a clear price before work begins.
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Inspect the joints round the windows every year or so
- Ask a joiner to look at soft timber first
- Plan mastic work ahead of painting
- Don’t run silicone over sand mastic
Do not touch or press the mastic while it hardens. It skins over quickly, but takes longer to harden fully.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.

Why it’s worth doing now in Broom Street
Not every filler suits an old window surround. Sand mastic is the like-for-like choice, which can matter on listed and conservation-area homes. Where a wall is exposed, as many are in small places like Broom Street, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.

When something else is needed
