Sand mastic for homes and businesses in West Lavington
Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. Common call-outs are for crumbling sand mastic round a window and cracked mastic round a front door frame, on tenement windows, period & listed homes and timber door frames.
Mastic can only go onto a dry, clean joint, so window work in West Lavington is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
You get a 12-month guarantee, the same in West Lavington as everywhere else we work.

Aftercare tips
How long the joints last depends on use and care. We suggest:
- Inspect the joints round the windows every year or so
- Take care around the mastic when scraping paint
- Renew mastic before redecorating the windows
- Get any rot dealt with first
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
Sound mastic protects the frame. Once it fails, water can sit against the timber and timber that stays wet can rot.
Signs you need sand mastic in West Lavington
Shallow joints are a common cause. Mastic that’s too thin cracks and drops out so we make sure the new mastic is the right thickness.
Any of these means the joints need attention:
- Draughty sash windows at the surround
- Cracked mastic round a front door frame
- Silicone on a period window that looks wrong
- Mastic that needs renewing before redecorating
For an older house near a landmark such as The Parish Church of St Mary Magdalene, the joint between an old wall and a newer frame is usually the first place rain gets in.

What sealant work cannot fix
Before booking, it’s worth knowing the limits too:

- Whether work needs listed building consent

West Lavington: your questions answered
Is there a guarantee on sand mastic in West Lavington?
All our work, in West Lavington and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Will you come out to West Lavington?
Yes, West Lavington is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Can tenants book the work?
Of course. Ask your landlord first, and we can send them the quote if that helps.
How much does sand mastic cost in West Lavington?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before any work starts.
How long does sand mastic take to go off?
It forms a skin fairly soon, then hardens over a longer period. The weather and joint depth both affect it.
Will there be a smell?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
How long does the job take?
Typically it takes anything from a few hours to a full day, depending on how many windows. Bigger jobs take longer.
How the visit works
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The job generally takes a few hours for a single window, longer for several. Somewhere like West Lavington needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We check the window surrounds and agree which joints need renewing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.
How to prepare
- Mention any leaks or damp you’ve noticed
- Mention any tricky access
- For business premises, tell us about site rules or sign-in

West Lavington homes and the weather
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Cowdray House (about 0.6 miles north) are a reminder that the area around West Lavington has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Managing a site like Midhurst CofE Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.

What the job involves on each surface
Timber door frames
Doors face weather and wear and the mastic can crack early. We rake it out and renew it.
Period and listed homes
On a listed home or in a conservation area, the right material matters. Sand mastic is often the preferred finish.
DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
A careful DIYer can reseal a simple joint, 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.
