Sand mastic in Hannington, done properly
We renew sand mastic around sash windows and doors in stone and brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. We work on period & listed homes, stone surrounds and brick reveals, and people most often call us about old cement repairs round a window that have failed and mastic worn away on windows facing the weather.
Around Hannington, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
Big or small, you get the same 12-month guarantee in Hannington and across Hampshire.

Hannington questions
Do you cover smaller places like Hannington?
Yes, Hannington is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Overton station?
Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or email us and tell us about the property, and we’ll send you a clear quote.
How long does sand mastic take?
That depends on how much there is to do, but as a guide it takes a few hours for a single window, longer for several. We’ll give you a better idea when we quote.
Do I need permission for sand mastic on a listed building?
It’s best to ask your local planning authority first. Like-for-like sand mastic is often the preferred finish, but they decide.
What’s sand mastic made of?
It’s a mix of sand and a linseed-oil-based binder. It’s applied by hand and finished to sit neatly against the masonry.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Do you remove the old sealant?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
Which is right for my windows, sand mastic or modern sealant?
It depends on the window. Period windows in stone or brick normally suit sand mastic, while modern frames normally get a flexible sealant.
For landlords and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
If you manage several properties in or around Hannington, several properties can go on one quote. Just tell us the addresses and what each one needs, and pictures by email help.
When something else is needed
In fairness, some problems need a different trade:
- Cracked or broken glass
- Sash cords, weights and draught-proofing of the sashes
- Rotten sashes, sills or window boxes (a joiner’s job)
If you’re not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer.

Frames and glazing around Hannington
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.
If you live in an older home near Church of All Saints, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Look over the window mastic once a year
- Avoid heavy scraping on the mastic joint
- Leave the new mastic unpainted
- Keep sills and gutters clear so water drains away
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber, which can lead to rot.
Signs you need sand mastic in Hannington
Sand mastic slowly weathers. It hardens, cracks and starts to come away from the frame or the masonry.
Signs it’s time to call us include:
- Mastic that needs renewing before redecorating
- Gaps where the frame meets the masonry
- Mastic worn away on windows facing the weather
- Mastic dropping out of the joint
For landlords with property near Overton station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

How we quote for sand mastic
Every job gets its own quote. This is what makes a difference:
- Whether the work is at height
- When we can work, for business premises
- Mould in or behind the old joints
- The product the joint needs
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
What we need to know
What to tell us when you ask for a quote:
- Where the property is
- What the problem is, such as mould, gaps, leaks or cracking
- Any previous sealing or DIY work
- Pictures of the joints, sent by email
Getting a quote is simple: let us know the job and the location and its rough size. Photos by email help us understand the job, and we will come back to you with a quote.
Leave it or put it right?
Draughts round a sash window aren’t always the sashes. Open mastic joints round the box can let air in, and renewing the mastic closes them. Where a wall is exposed, as many are in small places like Hannington, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, call 0345 464 0079 or send us an email and we will give you an honest view and a quote.
