Questions from Labour-in-vain
Do you cover smaller places like Labour-in-vain?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Yes, Labour-in-vain is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or email us with a few details of the job.
Should I check with the council before work on a listed or conservation-area home?
Speak to your local planning authority before work starts. Like-for-like sand mastic is often the preferred finish, but they decide.
Can new sealant go over the old?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Which products do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
What should I tell you?
Tell us what needs doing and where. If we need more, we’ll ask.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
Can sand mastic be painted?
Traditional guidance is not to paint over sand mastic. If you’re redecorating the window, ask us first and we will advise.
About our sand mastic in Labour-in-vain
We renew sand mastic around sash windows and doors in stone and brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. Common call-outs are for open joints round the window box and cracked mastic round a front door frame, on stone surrounds, sash and case windows and brick reveals.
Around Labour-in-vain, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
All of our work is guaranteed for twelve months.

Sand mastic in Labour-in-vain: local notes
With historic houses such as Old Soar Manor (about 4 miles south) nearby, there’s older building stock in the area around Labour-in-vain as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Managing a site like Wrotham School? Then the mastic around its windows and doors needs looking after like any other building’s. Letting a property close to Borough Green & Wrotham station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about.

Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Keep modern sealant off the mastic
- Look over the window mastic once a year
- Take care around the mastic when scraping paint
- Plan mastic work ahead of painting
Leave the new mastic alone while it firms up. It forms a skin fairly soon, but takes longer to harden fully.
Sound mastic protects the frame. Once it fails, water can sit against the timber and timber that stays wet can rot.
How the visit works
Every visit runs the same way: we check the joints, protect the area around them, carry out the job and clear up. It usually takes a few hours for a single window, longer for several. In a small place like Labour-in-vain, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic isn’t too thick.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
How to prepare
- For business premises, tell us about site rules or sign-in
- Let us know about stairs, lifts or work at height
- Clear the area around the work

What we are called out for in Labour-in-vain
Water gets into small cracks in the mastic and loosens it further. Exposed elevations normally fail first.
The problems people generally mention when they call include:
- Mastic that needs renewing before redecorating
- Crumbling sand mastic round a window
- Mastic round period door frames that has failed
- Draughts and rain around sash boxes
In the older streets around Church of St George, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

- Who does the work, and how experienced they are

Leave it or put it right?
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. Around Labour-in-vain, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Can I do it myself?
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, and the work is guaranteed for a year.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
