How we handle sand mastic in Small Hythe
A silicone bead around a sash window can look out of place and isn’t always the right material. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. If you are dealing with window mastic to renew ahead of painting and gaps between timber frames and stone or brick, we can help, on period & listed homes, sash and case windows and tenement windows alike.
Around Small Hythe, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or email us.

Sand mastic in Small Hythe: local notes
With historic houses such as Smallhythe Place (about 0.2 miles south) nearby, there’s older building stock in the area around Small Hythe as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
If you look after a building such as Homewood School and Sixth Form Centre, the mastic around its windows and doors needs looking after like any other building’s.

Do you need sand mastic in Small Hythe?
Age is the main cause. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.
Common reasons people contact us are:
- Draughts and rain around sash boxes
- Open joints round the window box
- Silicone on a period window that looks wrong
- Mastic that needs renewing before redecorating

How the visit works
On the day, we look over the joints with you first, so you know exactly what we’re doing. Surfaces next to the work are protected before we start. Most jobs take a few hours per window, depending on the condition of the joints. Somewhere like Small Hythe needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- The mastic is mixed, pressed into the joint by hand and shaped.
- We dress the surface so it sits neatly against the masonry.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Plan for the work area to be out of bounds to pets and children
- Move anything stored near the joints

Related advice
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

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 and that can be important for listed homes. Around Small Hythe, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, ring 0345 464 0079 or send us an email and we will give you an honest view and a quote.

How we quote for sand mastic
Jobs vary more than people expect. The main factors:
- Mould in or behind the old joints
- Whether the work is at height
- How much old sealant there is and how hard it is to remove
- The product the joint needs
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.
Asking for a quote
There’s no need for technical detail. It helps if you can tell us:
- Photos by email, if that is easy
- What’s wrong with the joints now
- How many joints, rooms or windows are involved

Small Hythe: your questions answered
Will you come out to Small Hythe?
Yes. Small Hythe 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.
Is Small Hythe in your area for sand mastic?
Yes. Our work covers London and the South East, and Small Hythe is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear quote.
Do you do commercial work?
Yes. Larger jobs can be planned room by room or area by area.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you do not need to watch us work.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Do you work for landlords and businesses?
Yes. We work in homes, commercial premises and hotels, and we’re fully insured.
Can new sealant go over the old?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
When it is not the sealant
Before you book, it’s worth knowing the limits:
- Rotten sashes, sills or window boxes (a joiner’s job)
- Cracked or broken glass
- Sashes that rattle, stick or won’t open
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly before you book.
