Looking after it afterwards
So the new joints stay in good condition:
- Don’t run silicone over sand mastic
- Find out about consent before window work on a listed home
- Do not paint over the new mastic
- Take care around the mastic when scraping paint
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. Painting over failed mastic hides the problem for a while.
Sand mastic for homes and businesses in Ampfield
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. Renewing it closes the gap and tidies the surround. Typical jobs include failed mastic on an exposed elevation and window mastic to renew ahead of painting, on stone surrounds, sash and case windows and period & listed homes.
Around Ampfield, 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.
Whatever the size of the job, you get the same one-year guarantee in Ampfield and across Hampshire.

Why it’s worth doing now in Ampfield
Draughts round a sash window are not always the sashes. Open mastic joints round the box can let air in, and renewing the mastic closes them. In a small place like Ampfield, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Combining jobs into one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

Ampfield homes and the weather
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.
Homes close to Church of St Mark include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For site and facilities teams at buildings such as Ampfield Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Chandlers Ford station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

Timber door frames
Sand mastic is used round timber door frames too. We renew it the same way as on windows.
Sash and case windows
On a sash window, the mastic joint shows on the outside so we finish it carefully.
What we do, step by step
There isn’t much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes a few hours per window, depending on the condition of the joints, including the tidy-up. In a small place like Ampfield, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.
Before we arrive
- Clear the area around the work
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about earlier repairs to the joints

FAQs for Ampfield
Can you do sand mastic in Ampfield?
Yes. We work across London and the South East, and Ampfield is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job.
I let a flat near Chandlers Ford station. Can you help?
Yes, we work for landlords and agents. Just call 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Is it possible to take out silicone and use sand mastic instead?
Yes, it’s a common request. All the old silicone is removed first so the mastic beds in well.
Can I paint the new mastic?
It’s traditionally left unpainted, as guidance on traditional windows advises. Ask us before decorating.
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
