Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Leave the new mastic unpainted
- Clear gutters so water does not pour onto the windows
- Sort the mastic before the decorators arrive
- Ask the planning authority about consent for listed or conservation-area homes
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
The process
We bring everything the job needs with us. Once we have agreed what’s being done, the area is protected and the work begins. Most jobs take anything from a few hours to a full day, depending on how many windows. Somewhere like Stuppington needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- Each surround is checked first.
- The joint is raked out and cleaned.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
Before we arrive
- Move anything stored near the joints
- Tell us about access, such as stairs, a lift or high-level joints
- Where the joints are inside, avoid wetting them before we arrive

What the job involves on each surface
Stone surrounds
Old stone surrounds are often uneven, so the joint varies in width. Sand mastic is shaped by hand to suit.
Tenement and terrace windows
Tenements and terraces often have many sash windows with ageing mastic. We work on single windows or whole elevations.
Stuppington questions
Is Stuppington within the area you cover?
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.
I let a flat near Canterbury East station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can call 0345 464 0079 or email us with the details for a clear quote.
Is it OK to seal over old sealant?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
Can I add another job to the visit?
Yes. Just list everything you need and you will get one quote.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
Does someone need to be in?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Common problems we fix in Stuppington
Previous repairs in cement or silicone often trap water or crack away. They don’t suit the joint, and they generally need raking out.
If you can see any of these, it’s time to have the joints looked at:
- Draughty sash windows at the surround
- Gaps where the frame meets the masonry
- Window mastic to renew ahead of painting
- Crumbling sand mastic round a window
For an older house near a landmark such as Church of St Nicholas, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
