Sand mastic in Harbridge, done properly
We renew sand mastic around sash windows and doors set in stone or brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. Typical jobs include cement or filler used on old window joints that has cracked and old sand mastic that has cracked, crumbled or fallen out, across timber door frames, period & listed homes and brick reveals.
Somewhere as small as Harbridge, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Whatever the size of the job, you get the same one-year guarantee.

Harbridge: your questions answered
Is sand mastic in Harbridge guaranteed?
All our work, in Harbridge and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Can you do sand mastic in Harbridge?
Yes, Harbridge is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or send us an email and let us know what needs doing, and we will send you a clear quote.
Should I use sand mastic or silicone?
It depends on the window. On many period windows, sand mastic looks right and suits the building and newer frames usually get a flexible sealant.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Can you replace silicone on a period window with sand mastic?
Often, yes. With the silicone removed and the joint cleaned we point it with sand mastic.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Can tenants book the work?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
Can landlords and businesses book you?
Yes, regularly. We can quote for several properties at once, and between tenancies is a good time for the work.
Surface by surface
Stone surrounds
The stone is treated with care while raking out the old mastic.
Period and listed homes
Sand mastic is the like-for-like choice for many period homes. On listed buildings, check with your planning authority first.
What we cannot put right
New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:
- Planning or listed building consent (your local planning authority decides)
- Sash cords, weights and draught-proofing of the sashes
- Putty and glazing repairs
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly.

How it works
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a single window, longer for several. In a small place like Harbridge, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
How to prepare
- For business premises, tell us about site rules or sign-in
- Mention any tricky access
- Keep pets and children clear of the area while we work

Advice
Common problems we fix in Harbridge
Water gets into small cracks in the mastic and loosens it further. Windows facing the weather tend to go first.
Any of these means the joints need attention:
- Mastic worn away on windows facing the weather
- Mastic dropping out of the joint
- Wind and rain getting in round a sash window
- Modern sealant on a period surround
For an older house near a landmark such as Church of All Saints, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
What your quote should include
- Whether they’re fully insured
- What happens if the job turns out different
- Is VAT in the price?
- Whether all the old sealant comes out first
What affects the quote in Harbridge
Jobs vary more than people expect. The main factors:
- How much old sealant there is and how hard it is to remove
- How much there is to do
- The product the joint needs
- Any mould that needs treating
What you pay reflects the work, not guesswork. That’s why we ask about the job first and give you a clear price before any work starts.
What to tell us for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- How we’d reach the joints
- The problem you’ve noticed
- Whether it has been sealed before
- The address or postcode of the job

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Sort the mastic before the decorators arrive
- Keep sills and gutters clear so water drains away
- Check the mastic when you check the paintwork
- Find out about consent before window work on a listed home
Do not touch or press the mastic while it hardens. It forms a skin fairly soon but needs longer to fully harden.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
Why deal with it now?
New sash windows are a major, costly change, and in listed buildings it may need consent. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Older cottages and farmhouses around Harbridge can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

- Homes, businesses and hotels
- Approved under the ARBOMaster scheme
