About our sand mastic in Victoria
Across Victoria, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand, finished to suit the masonry. If you have weathered mastic on the most exposed windows and modern sealant on a period surround, we can put it right, on timber door frames, brick reveals and sash and case windows alike.
Many London homes are flats, with windows high above the street. In a converted house or block, the lease usually says who is responsible for the windows, so it’s worth checking before booking, and access in Victoria is something to talk through when you book.
Big or small, you get the same one-year guarantee in Victoria and across Greater London.

Can I do it myself?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Leave it or put it right?
An open joint round the frame lets weather in. Water can get to the frame and the masonry so renewing it early protects the window. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble for homes in Victoria.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and give you a clear quote before work begins.

How do I get a quote for sand mastic in Victoria?
Every job is different, so each one gets its own quote. To get one, ring 0345 464 0079 or email us with a short description of the job.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
How long does sand mastic take to harden?
The surface skins quite quickly and it hardens fully over a longer time. The weather and joint depth both affect it.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
Can I choose the sealant colour?
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.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
How we quote for sand mastic
Your quote is based on your job. We look at:
- Any working-time requirements on site
- The size of the job
- The type of sealant required
- How much old sealant there is and how hard it is to remove
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.
Asking for a quote
When you call or email, it’s useful to know:
- Access, such as stairs, a lift or height
- Photos by email, if that’s easy
- What the problem is, such as mould, gaps, leaks or cracking
- Whether it’s a home or a business
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. Whenever you are ready, call 0345 464 0079 or email us.
How to look after the new joints
To keep the joints looking good and working properly:
- Keep sills and gutters clear so water drains away
- Avoid patching sand mastic with silicone
- Find out about consent before window work on a listed home
- Take care around the mastic when scraping paint
Leave the new mastic alone while it firms up. It skins over quickly but needs longer to fully harden.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.

Windows and doors in Victoria
Historic houses like Buckingham Palace (about 0.4 miles north) are a reminder that the area around Victoria has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Victoria is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. Schools such as St Peter's Eaton Square CofE Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
