Sherfield English questions
Do you cover smaller places like Sherfield English?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
I let a flat near Mottisfont & Dunbridge station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We will tell you what we’re using and why.
Do I have to be there?
Access is agreed with you when the job is booked. Indoors, that normally means someone at home.

Yes. We are fully insured for domestic and commercial work.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Will the old sealant be removed?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.

Sand mastic for homes and businesses in Sherfield English
Sand mastic does not last for ever and gaps open up round the frame. Renewing it closes the gap so the surround looks right again. We work on timber door frames, tenement windows and sash and case windows, and the jobs we see most are window mastic to renew ahead of painting and patchy fillers round a sash window.
Somewhere as small as Sherfield English, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
We stand behind the work with a 12-month guarantee.

Common problems we fix in Sherfield English
Previous repairs in cement or silicone often trap water or crack away. They don’t suit the joint and we normally remove them.
The most common problems we see are:
- Old sand mastic that has cracked, crumbled or fallen out
- Mastic that needs renewing before redecorating
- Cement or filler used on old window joints that has cracked
- A silicone bead on a sash window that spoils the look
For an older house near a landmark such as Church of St Leonard, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
What to look for in a quote
- Whether the sealant suits the joint
- Whether they seal over old material or remove it
- Who does the work, and how experienced they are
- Is VAT in the price?
Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.

Advice
What sand mastic looks like in Sherfield English
With historic houses such as Landford Manor (about 2.2 miles south-west) nearby, there’s older building stock in the area around Sherfield English 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’s traditional sand mastic. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Go gently near the mastic when preparing windows
- Plan mastic work ahead of painting
- Don’t paint over the new mastic
- Inspect the joints round the windows every year or so
Avoid painting over the new mastic, as traditional guidance advises. Ask us before any decorating around it.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
Why act early in Sherfield English
Cement-based fillers and modern sealants don’t always suit a period surround. Sand mastic is the like-for-like choice and that can be important for listed homes. Older cottages and farmhouses around Sherfield English can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
