What we do, step by step
We bring everything the job needs with us. After a quick look at the joints together, we protect the area and start. It normally takes anything from a few hours to a full day, depending on how many windows. Somewhere as small as Culverstone Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic isn’t too thick.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.

Signs you need sand mastic in Culverstone Green
Shallow joints are a common cause. A thin layer does not hold well, which is why we pack deep voids first and get the depth right.
Most people get in touch after spotting one of these:
- Old cement repairs round a window that have failed
- Wind and rain getting in round a sash window
- Window mastic to renew ahead of painting
- Gaps round a timber door in stone or brick
If you look after a building such as Culverstone Green Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Culverstone Green questions
Is Culverstone Green within the area you cover?
Yes. Culverstone Green is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you do sand mastic in Culverstone Green?
Yes, Culverstone Green is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear quote.
Can you do several jobs on one visit?
Yes. Several rooms, windows or areas can go on one quote.
Can you seal over the old sealant?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
What do you need from me for a quote?
Tell us what needs doing and where, plus pictures if you have them. If we need more, we’ll ask.
Do you work for landlords and businesses?
Yes, regularly. Several properties can be quoted together, and between tenancies is a good time for the work.
When will the new mastic be hard?
It skins over fairly quickly but takes longer to harden fully. We’ll explain what to expect before we leave.
Where do you work from?
Mr Mastic is based in Crawley. Our applicators cover Culverstone Green, along with the rest of our area.
What happens if it’s left?
An open joint round the frame lets weather in. Left, water can reach the timber and the wall, so dealing with it now protects both. Around Culverstone Green, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
