Sand mastic for sash & case windows in Farlington, Portsmouth
Sand mastic across Farlington and nearby, with every bit of old sealant taken out first.
- Gaps where the frame meets the masonry
- Old sand mastic that has cracked, crumbled or fallen out
- Draughts and rain around sash boxes
Sand mastic in Farlington
Fresh sand mastic forms a skin quite soon, but it takes longer to harden fully. Traditional guidance is not to paint over it and we’ll advise if you are redecorating. We work on tenement windows, period & listed homes and timber door frames, and common reasons people get in touch are cement or filler used on old window joints that has cracked and gaps where the frame meets the masonry.
In a smaller place like Farlington, some walls face open ground and catch the full force of the weather. That’s hard on the mastic around frames and sills.
Whatever the size of the job, you get the same 12-month guarantee.

When to call us in Farlington
Timber frames move with the seasons. The movement cracks the mastic over time.
It’s worth asking for a quote if you see:
- Mastic round period door frames that has failed
- Tired mastic found when preparing windows for paint
- Failed mastic on an exposed elevation
- Crumbling sand mastic round a window
Schools such as Solent Infant School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

What happens on the day
All our tools and materials come with us in the van. Once we have agreed what’s being done, we protect the area and start. It normally takes a few hours per window, depending on the condition of the joints. A visit to Farlington is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
Getting ready for the visit
- Clear items away from the joints we are working on
- Mention any sign-in or site rules at work premises
- Mention if the joints have been sealed before

Windows and doors in Farlington
Farlington is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around older windows and doors, especially on the side facing the sea. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For landlords with property near Cosham station, older sash windows in a rental need their mastic kept sound to keep the weather out. Homes close to Church of St Andrew include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Common questions in Farlington
Do you cover smaller places like Farlington?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you work for landlords with property near Cosham station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
How long will you be here?
Most jobs take a few hours for a single window, longer for several, including preparation and clearing up. Your quote will say how long we expect yours to take.
Should I check with the council before work on a listed or conservation-area home?
Yes, it’s worth checking. Your local planning authority can say if consent is needed for work on a listed home or in a conservation area.

Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or email us.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.

When will the new mastic be hard?
Not right away. The skin forms first, and the full set comes later, and we’ll tell you what to expect.
Landlords, agents and businesses in Farlington
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will quote.
Keeping the joints in good condition
Looking after new joints is easy:
- Check the mastic when you check the paintwork
- Have rotten timber repaired before new mastic goes in
- Take care around the mastic when scraping paint
- Keep modern sealant off the mastic
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger as more mastic falls out.
What we can’t put right
We won’t take on work that will not last, so here’s what sealant cannot put right:
- Planning or listed building consent (your local planning authority decides)
- Rotten sashes, sills or window boxes (a joiner’s job)
- Masonry that needs repairing
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly before you book.
Surfaces we seal
- Stone surrounds
- Brick reveals
- Sash and case windows
- Period & listed homes
- Timber door frames
- Tenement windows
Why act early in Farlington
Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry so renewing it early protects the window. In an older home around Farlington, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
