About our sand mastic in Arborfield
For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. We work on sash and case windows, period & listed homes and timber door frames, and common reasons people get in touch are tired mastic found when preparing windows for paint and mastic round period door frames that has failed.
Somewhere as small as Arborfield, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

Sand mastic in Arborfield: local notes
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For landlords with property near Winnersh station, older sash windows in a rental need their mastic kept sound to keep the weather out. For site and facilities teams at buildings such as The Coombes Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around Church of St Bartholomew, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Advice
FAQs for Arborfield
Do you work for landlords with property near Winnersh station?
Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.
Is Arborfield within the area you cover?
Yes, Arborfield is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Are you fully insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Can old silicone round a sash window be swapped for sand mastic?
Often, yes. With the silicone removed and the joint cleaned, sand mastic is applied by hand.
What is sand mastic?
A traditional pointing material made from sand and a linseed-oil-based binder for the joint between timber frames and masonry.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
When will the new mastic be hard?
Not right away. It skins first and hardens fully later and we’ll give you an idea for your job.
Why act early in Arborfield
If you are redecorating, renew the mastic first. Painting over failed mastic does not seal it and traditional guidance is to leave the new mastic unpainted. Older cottages and farmhouses around Arborfield can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
Why us?
- Any old sealant cut out fully, not covered over
- Domestic, commercial and hotel work
- 180+ five-star Google reviews
- An ARBOMaster approved applicator

DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Quotes for sand mastic in Arborfield
There’s no set price list, because no two jobs are the same. The quote depends on:
- Access and height
- Any working-time requirements on site
- The amount of work
- Which sealant suits the joint
The cost depends on the amount of work, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.
Asking for a quote
Photos by email are helpful but not essential. Please mention:
- What’s wrong with the joints now
- Whether it has been sealed before
- Pictures of the joints, sent by email
- Whether it’s a home or a business
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
Looking after it afterwards
So the new joints stay in good condition:
- Clear gutters so water doesn’t pour onto the windows
- Check with your local planning authority if your home is listed
- Renew mastic before redecorating the windows
- Have rotten timber repaired before new mastic goes in
Avoid painting over the new mastic, as traditional guidance advises. If you’re redecorating, ask us first.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.
