Sand mastic in Crookham, done properly
A silicone bead around a sash window can look out of place and doesn’t suit the building. Sand mastic is the traditional choice and we can swap the silicone for it. Typical jobs include cracked mastic round a front door frame and mastic that needs renewing before redecorating, across brick reveals, period & listed homes and stone surrounds.
In a village or hamlet like Crookham, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Every job is covered by our one-year guarantee, wherever you are in West Berkshire.

Different surfaces, different methods
Brick reveals
Sand mastic is also used where timber frames meet brick. It suits older brickwork.
Sash and case windows
On a sash window, the mastic joint shows on the outside, so a neat, even finish matters.
What sand mastic looks like in Crookham
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Shaw House (about 5 miles north-west) nearby, there’s older building stock in the area around Crookham as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
For landlords with property near Thatcham station, cracked sand mastic around sash windows lets in the draughts tenants complain about. For an older house near a landmark such as Church of St Peter, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Schools such as Brimpton C.E. Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Do not run silicone over sand mastic
- Find out about consent before window work on a listed home
- Ask a joiner to look at soft timber first
- Keep sills and gutters clear so water drains away
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
Once mastic starts to crumble, rain gets in. That water can reach the timber frame and the wall so early renewal protects both.

Can I do it myself?
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.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
What we do, step by step
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours for a single window, longer for several. Somewhere like Crookham 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.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.
How to prepare
- Mention any sign-in or site rules at work premises
- Tell us about any previous sealing or DIY attempts
- Move anything stored near the joints

Advice
Crookham: your questions answered
Is Crookham in your area for sand mastic?
Yes. Our work covers London and the South East, and Crookham is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job.
Is Crookham within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can landlords and businesses book you?
Yes, regularly. Several properties can go on one quote, and between tenancies is a good time for the work.
How long does sand mastic take to harden?
It forms a skin fairly soon, then hardens over a longer period. The weather and joint depth both affect it.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
How long does the job take?
Typically it takes a few hours for a single window, longer for several. Bigger jobs take longer, and we will tell you how long to expect.
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 tell you what we are using.
