Sand mastic across Windsor and Maidenhead: what to expect
Fresh sand mastic forms a skin quite soon, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted and we’ll advise if you are redecorating. We work on sash and case windows, brick reveals and tenement windows, and people most often call us about open joints round the window box and a silicone bead on a sash window that spoils the look.
At the end, we look at the finished work together and explain the cure time. The work normally takes a few hours per window, depending on the condition of the joints, depending on the size of the job.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
What you will pay
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.

Windows and doors across Windsor and Maidenhead
Windsor and Maidenhead has everything from older homes with timber frames to newer ones with uPVC. Exposed walls are where window sealant normally fails first, wherever they are in Windsor and Maidenhead.
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings. For any job in Windsor and Maidenhead, joints are cleaned back properly before anything new goes in.
Maidenhead: For landlords with property near Maidenhead station, any sash windows need sound mastic to keep draughts and rain out. For site and facilities teams at buildings such as Claires Court Schools, the mastic around its windows and doors needs looking after like any other building’s.
When it isn’t the sealant
We will not take on work that will not last, so here’s what sealant can’t put right:
- Sashes that need overhauling
- Rotten sashes, sills or window boxes (a joiner’s job)
- Cracked or broken glass
Different surfaces, different methods
Timber door frames
Period doors in stone or brick openings are often pointed with sand mastic. The method is the same as for windows.
Sash and case windows
On a sash window, the mastic joint shows on the outside, so a neat, even finish matters.
Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Quotes for sand mastic in Windsor and Maidenhead
The price is agreed before any work begins. It’s based on:
- The size of the job
- The type of sealant required
- Whether there’s mould to deal with
- Working hours on commercial sites
The cost depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts.
Asking for a quote
Photos help, but a description is a good start. Try to tell us:
- How many joints, rooms or windows are involved
- What’s wrong with the joints now
- Pictures of the joints, sent by email
- Access, such as stairs, a lift or height
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Sort the mastic before the decorators arrive
- Take care around the mastic when scraping paint
- Keep sills and gutters clear so water drains away
- Leave the new mastic unpainted
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Sound mastic protects the frame. Failed mastic lets water reach the timber, which can lead to rot.

Should I check with the council before work on a listed or conservation-area home?

All our work has a 12-month guarantee.
