Longparish Sand Mastic
Window and door surrounds in Longparish need attention? We remove the old material, prepare the joints and seal them properly, with a 12-month guarantee.
- A silicone bead on a sash window that spoils the look
- Gaps round a timber door in stone or brick
- Cement or filler used on old window joints that has cracked
How the job changes by surface
Timber door frames
Door frames get knocked and soaked, so their mastic can fail sooner. We rake it out and renew it.
Stone surrounds
Stone surrounds suit sand mastic well. The finish blends with the masonry.
Sand mastic for homes and businesses in Longparish
Silicone on a period window often looks wrong and is not always the right material. Sand mastic gives a finish that matches the age of the house, and we can replace one with the other. We work on timber door frames, sash and case windows and brick reveals, and the jobs we see most are cracked mastic round a front door frame and modern sealant on a period surround.
In a village or hamlet like Longparish, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
All our work is covered by a 12-month guarantee.

How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Sort the mastic before the decorators arrive
- Avoid patching sand mastic with silicone
- Go gently near the mastic when preparing windows
- Don’t paint over the new mastic
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.
What happens on the day
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours per window, depending on the condition of the joints. Somewhere as small as Longparish, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Mention any parking rules near the property
- Tell us about access, such as stairs, a lift or high-level joints

Advice
Why deal with it now?
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic is the traditional material and finishes neatly against the masonry. Around Longparish, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Windows and doors in Longparish
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Rented homes near Whitchurch (Hampshire) station change hands often, and any sash windows need sound mastic to keep draughts and rain out. If you look after a building such as Longparish Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s. Homes close to Church of St Nicholas include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in.

For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Are you fully insured?
Yes, we’re fully insured for every job we do.

Do I need permission for sand mastic on a listed building?
Checking first is sensible. Your local planning authority can say if consent is needed for work on a listed home or in a conservation area.
