Sand Mastic in Penton Mewsey
Problem with your window and door surrounds in Penton Mewsey? We cut out the old, prepare the joints and apply the right sealant.

About our sand mastic in Penton Mewsey
Sand mastic does not last for ever and gaps open up round the frame. Renewing it closes the gap so the surround looks right again. Common call-outs are for open joints round the window box and crumbling sand mastic round a window, on sash and case windows, brick reveals and stone surrounds.
Homes in small places like Penton Mewsey often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
Every job is covered by our 12-month guarantee, wherever you are in Hampshire.

How it works
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes anything from a few hours to a full day, depending on how many windows. In a small place like Penton Mewsey, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- 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.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Clear items away from the joints we are working on
- Let us know about stairs, lifts or work at height

Advice
What sand mastic looks like in Penton Mewsey
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.
For site and facilities teams at buildings such as Harrow Way Community School, larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near Andover station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Leave it or put it right?
If you are redecorating, renew the mastic first. Painting over failed mastic doesn’t seal it, and the new mastic is traditionally left unpainted. Around Penton Mewsey, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

When to call us in Penton Mewsey
Decorating can disturb tired mastic. Many people find it crumbling when they prepare the windows, which is a good time to renew it.
These are the problems we are asked about most:
- Draughty sash windows at the surround
- Old sand mastic that has cracked, crumbled or fallen out
- Cracked mastic round a front door frame
- Patchy fillers round a sash window
If you live in an older home near Holy Trinity Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Questions to ask before you book
- What guarantee comes with the work
- Which colour the sealant will be
- What the quote includes, VAT included or not
- Whether all the old sealant comes out first
What the job involves on each surface
Sash and case windows
On a sash window, the mastic joint shows on the outside so we finish it carefully.
Period and listed homes
On a listed home or in a conservation area, the right material matters. Like-for-like sand mastic is normally favoured.
Penton Mewsey: your questions answered
Do you work for landlords with property near Andover station?
Yes, we work for letting agents and landlords. Just call 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear price.
Do you cover Penton Mewsey for sand mastic?
Yes, Penton Mewsey is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or email us with a few details of the job.
Do you work for hotels and businesses?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
Is it possible to take out silicone and use sand mastic instead?
Usually, yes. With the silicone removed and the joint cleaned we point it with sand mastic.
Can you quote for more than one area?
Yes. Several rooms, windows or areas can go on one quote.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
Do I need permission for sand mastic on a listed building?
Speak to your local planning authority before work starts. Like-for-like sand mastic is often the preferred finish, but they decide.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
