Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Get any rot dealt with first
- Take care around the mastic when scraping paint
- Inspect the joints round the windows every year or so
- Leave the new mastic unpainted
Don’t run silicone over the new mastic. If anything cracks, get it looked at before trying a quick fix.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.
Sand mastic in Halfway Houses
Sand mastic doesn’t last for ever and gaps open up round the frame. Renewing it closes the gap and tidies the surround. If you’re dealing with crumbling sand mastic round a window and mastic that needs renewing before redecorating, we can put it right, whatever the surface.
Around Halfway Houses, conservatories, garden rooms and patio doors are often part of the house. Those joints need the same attention as the main windows.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What else we do in Halfway Houses
What sand mastic looks like in Halfway Houses
Halfway Houses is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. 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.
For landlords with property near Queenborough station, older sash windows in a rental need their mastic kept sound to keep the weather out.

What happens on the day
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours per window, depending on the condition of the joints and we leave things clean and tidy. For a job in Halfway Houses, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Mention if the joints have been sealed before
- Move anything stored near the joints

Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What sealant work cannot fix
It helps to know what we cannot do too:
- Decayed frames that need repair
- Crumbling stone or brickwork round the window
- Planning or listed building consent (your local planning authority decides)
If you’re not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer.
What we seal
- Timber door frames
- Tenement windows
- Period & listed homes
- Brick reveals
- Stone surrounds
- Sash and case windows

Common questions in Halfway Houses
Does the coastal weather in Halfway Houses affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Will you come out to Halfway Houses?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can old silicone round a sash window be swapped for sand mastic?
Usually, yes. With the silicone removed and the joint cleaned, sand mastic is applied by hand.
What information do you need?
A short description and the location. If we need more, we’ll ask.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Can you seal over the old sealant?
No, it won’t last. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Can I add another job to the visit?
Yes, we can. More than one area can be quoted together.
Where is Mr Mastic based?
We work from Crawley. We cover Halfway Houses and the rest of Kent.
Signs you need sand mastic in Halfway Houses
Sand mastic slowly weathers. It hardens, cracks and starts to come away from the frame or the masonry.
Most people get in touch when they notice something like this:
- Old sand mastic that has cracked, crumbled or fallen out
- A silicone bead on a sash window that spoils the look
- Failed mastic on an exposed elevation
- Gaps round a timber door in stone or brick
For site and facilities teams at buildings such as Halfway Houses Primary School, its window and door frames need their mastic kept sound, just like a home’s.
