Common questions in Lower Common
Do you work for landlords with property near Crowthorne station?
Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.
Do you cover Lower Common for sand mastic?
Yes, Lower Common is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we will give you a clear quote.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in.
Do you remove the old sealant?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Should I check with the council before work on a listed or conservation-area home?
It’s best to ask your local planning authority first. Like-for-like sand mastic is often the preferred finish but the decision is theirs.
Where are you based?
Mr Mastic is based in Crawley. We cover Lower Common and the rest of Hampshire.
What guarantee comes with the work?
Every job comes with our 12-month guarantee, and we are fully insured.
How we handle sand mastic in Lower Common
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s made from sand and a linseed-oil-based binder and built up by hand. On period homes, it looks right where silicone wouldn’t. Typical jobs include patchy fillers round a sash window and failed mastic on an exposed elevation, on brick reveals, sash and case windows and stone surrounds.
Mastic can only go onto a dry, clean joint, so window work in Lower Common is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
There’s a 12-month guarantee on every job, large or small.

Do you need sand mastic in Lower Common?
Most of it is simply age. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.
Keep an eye out for these signs:
- Open joints round the window box
- Tired mastic found when preparing windows for paint
- Cement or filler used on old window joints that has cracked
- Wind and rain getting in round a sash window
Letting a property close to Crowthorne station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about.

Windows and doors in Lower Common
Historic houses like Stratfield Saye House (about 4.3 miles west) are a reminder that the area around Lower Common has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Schools such as Charles Kingsley's Church of England Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. In the older streets around Church of St Mary, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Aftercare tips
To keep the joints looking good and working properly:
- Make sure water runs off the sill
- Do not paint over the new mastic
- Don’t run silicone over sand mastic
- 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.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens.
What happens on the day
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a single window, longer for several. For a village or hamlet like Lower Common, 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.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
Preparing for the visit
