What affects the cost of sand mastic
There’s no set price list. The quote depends on:
- Any mould that needs treating
- Working hours on commercial sites
- How many rooms, windows or areas are involved
- The amount of work
The cost depends on the amount of work, 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.
What we need to know
You do not need to know the technical terms. It helps if you can tell us:
- If it’s domestic, commercial or a hotel
- The address or postcode of the job
- Any previous sealing or DIY work
- Pictures of the joints, sent by email
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we’ll explain what’s involved.
Sand mastic for homes and businesses in St Ives
We renew sand mastic around sash windows and doors set in stone or brick. The old mastic is raked out, and new mastic is applied and shaped by hand. We work on tenement windows, timber door frames and stone surrounds, and the jobs we see most are weathered mastic on the most exposed windows and old sand mastic that has cracked, crumbled or fallen out.
In a village or hamlet like St Ives, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
Your job is guaranteed for a year, as with all our work.

What we do, step by step
There’s no need to move everything out, just the space around the work. We protect the rest, and the work takes a few hours per window, depending on the condition of the joints in most cases. For a village or hamlet like St Ives, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Mention any sign-in or site rules at work premises
- Tell us about any water getting in

Advice
Common problems we fix in St Ives
Water gets into small cracks in the mastic and pushes it out. Exposed elevations normally fail first.
These are the problems we’re asked about most:
- Gaps round a timber door in stone or brick
- Modern sealant on a period surround
- Mastic dropping out of the joint
- Open joints round the window box
If you live in an older home near All Saints, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What sand mastic looks like in St Ives
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Avon Tyrrell House (about 4.5 miles south-east) nearby, there’s older building stock in the area around St Ives as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
If you look after a building such as St Ives Primary & Nursery School, the mastic around its windows and doors needs looking after like any other building’s.

How the job changes by surface
Brick reveals
We rake out the old mastic and pack deep voids before pointing.
Tenement and terrace windows
Where a building is shared, window work may involve neighbours so it’s worth checking responsibilities.
Honest limits
It helps to know what we can’t do too:
- Damaged stone surrounds
- Decayed frames that need repair
- Whether work needs listed building consent
If you’re not sure, just call 0345 464 0079 or email us and we will give you a straight answer before booking.
Surfaces we seal
- Timber door frames
- Sash and case windows
- Period & listed homes
- Brick reveals
- Tenement windows
- Stone surrounds
Looking after it afterwards
Looking after new joints is easy:
- Have rotten timber repaired before new mastic goes in
- Leave the new mastic unpainted
- Check the mastic when you check the paintwork
- Find out about consent before window work on a listed home
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.
Why deal with it now?
Draughts round a sash window aren’t always the sashes. Open mastic joints round the box can let air in and new mastic seals them. Where a wall is exposed, as many are in small places like St Ives, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Can you work on commercial sites?

Which is right for my windows, sand mastic or modern sealant?
We will help you decide. Sand mastic suits many period homes, and modern sealants suit newer frames.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
