For landlords and businesses
We work for landlords and letting agents as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
How we handle window mastic in Standon
The new joint does not have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the line suits the frame instead of standing out. We work on timber windows & doors, window sills and uPVC windows, and the jobs we see most are draughts coming in around windows and doors and old mastic that has gone black or come away.
In a village or hamlet like Standon, 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.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Frames and glazing around Standon
With historic houses such as Much Hadham Palace (about 2.7 miles south-east) nearby, there’s older building stock in the area around Standon 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. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you look after a building such as Roger De Clare First CofE School, its window and door frames need their mastic kept sound, just like a home’s. For an older house near a landmark such as Church of St Mary, the joint between an old wall and a newer frame is generally the first place rain gets in.
Standon is about 5 miles north-east of Ware, in Hertfordshire. Across the SG11 area, our applicators can take on window mastic. Standon is one of 381 towns and villages in Hertfordshire we cover for window mastic. There’s also a page for Chelmsford, roughly 22 miles from Standon.

Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Wash the frames with mild soapy water
- Ventilate rooms so frames do not stay wet inside
- Repaint timber before it’s bare
- Check the mastic once a year
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
Honest limits
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- Condensation trapped between the panes
- Faulty window hardware
- Rotten timber, which needs a joiner first
If you’re not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer.

DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
If you’re set on DIY, put the effort into 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.
Common questions in Standon
Do you cover smaller places like Standon?
Yes. Standon 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 window mastic in Standon?
Yes, Standon is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access.
What should I tell you?
Let us know what needs doing and where, with photos by email if possible. If we need more, we will ask.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
How long will my window job take?
The work takes a morning for a couple of windows and a door. Access and the amount of old mastic make the biggest difference.
Is the new sealant paintable?
Silicone generally will not take paint. Let us know beforehand, and we will use a paintable product where it suits.
Leave it or put it right?
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. In a small place like Standon, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What you pay reflects the work, not guesswork. That’s why we ask about the job first and agree the price before starting.

What the job involves on each surface
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. Most leaks start at the bottom corners, so they get particular care.
Window sills
Masonry sills can have joints where water gets in, and the joint under the frame can let rain run behind. We seal those with a sealant suited to masonry.
