Sand mastic for homes and businesses in Nob's Crook
Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. We rake it out and renew it so the surround looks right again. We work on stone surrounds, tenement windows and period & listed homes, and common reasons people get in touch are modern sealant on a period surround and old cement repairs round a window that have failed.
In a village or hamlet like Nob's Crook, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
Whatever the size of the job, it’s backed by our one-year guarantee.

What the job involves on each surface
Stone surrounds
The stone is treated with care while raking out the old mastic.
Timber door frames
Period doors in stone or brick openings are often pointed with sand mastic. The method is the same as for windows.
Sand mastic in Nob's Crook: local notes
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like South Stoneham House (about 4.6 miles south-west) are a reminder that the area around Nob's Crook has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you live in an older home near Church of the Holy Trinity, the joint between an old wall and a newer frame is generally the first place rain gets in. For site and facilities teams at buildings such as Colden Common Primary School, its window and door frames need their mastic kept sound, just like a home’s.

What’s near Nob's Crook
Around Nob's Crook, our work takes us to homes and buildings near Wyvern Technology College and The Fox & Hounds pub and the streets around them. For rail, the closest station is Eastleigh station, about 2.2 miles south-west of the centre. Other landmarks nearby include Wolvesey Castle (4.8 miles north) and Moorgreen Hospital (4.2 miles south). The countryside around Nob's Crook includes Twyford Down and Shawford Down.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Check the mastic when you check the paintwork
- Ask the planning authority about consent for listed or conservation-area homes
- Keep modern sealant off the mastic
- Keep sills and gutters clear so water drains away
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
Nob's Crook: your questions answered
Will you come out to Nob's Crook?
Yes. Nob's Crook 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 seal over the old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. It all has to come out first.

Why it’s worth doing now in Nob's Crook
New mastic over crumbling mastic won’t hold. Raking out and preparing the joint gives it a sound base so the new work lasts. Where a wall is exposed, as many are in small places like Nob's Crook, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.
