How it works
You don’t need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the job takes a few hours for a single window, longer for several in most cases. Somewhere as small as Albourne Street, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we look at the surrounds with you and agree what needs doing.
- Old, loose 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.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Try not to wet indoor joints just before the visit
- Mention any parking rules near the property

Leave it or put it right?
Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry, so dealing with it now protects both. In a small place like Albourne Street, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, phone 0345 464 0079 or send us an email and we will give you an honest view and a quote.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Windows and doors in Albourne Street
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In the older streets around The Parish Church of St Bartholomew, the joint between an old wall and a newer frame is generally the first place rain gets in. For landlords with property near Hassocks station, any sash windows need sound mastic to keep draughts and rain out. For site and facilities teams at buildings such as Albourne CofE Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Quotes for sand mastic in Albourne Street
We quote each job individually. These are the things that affect it:
- How many rooms, windows or areas are involved
- Mould in or behind the old joints
- Working hours on commercial sites
- The number and length of the joints
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first.
What to tell us for a quote
There’s no need for technical detail. It helps if you can tell us:
- If it’s domestic, commercial or a hotel
- A few photos by email, if you can
- Access, such as stairs, a lift or height
- The problem you’ve noticed
Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we’ll talk you through the work and give you a clear price.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Make sure water runs off the sill
- Check the mastic when you check the paintwork
- Ask a joiner to look at soft timber first
- Take care around the mastic when scraping paint
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.

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.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
What information do you need?
A short description and the location, plus pictures if you have them. If we need more, we’ll ask.
How long does sand mastic take to go off?
It forms a skin fairly soon and it hardens fully over a longer time. The weather and joint depth both affect it.
I’m a tenant. Can you help?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
Can you replace silicone on a period window with sand mastic?
Yes, it’s a common request. All the old silicone is removed first so the mastic beds in well.
Different surfaces, different methods
Brick reveals
Sand mastic is also used where timber frames meet brick. It suits older brickwork.
Timber door frames
Door frames get knocked and soaked and the mastic can crack early. It’s renewed by hand.
