Landlord and commercial work in Mountfield
We work for landlords and agents as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.
In hotels, rooms out of use cost money, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
Sand mastic in Mountfield, done properly
Sand mastic does not last for ever and gaps open up round the frame. Renewing it closes the gap and tidies the surround. We work on period & listed homes, tenement windows and brick reveals, and common reasons people get in touch are cracked mastic round a front door frame and draughts and rain around sash boxes.
Around Mountfield, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
A 12-month guarantee comes as standard.

When to call us in Mountfield
Paint, silicone or cement used over old mastic causes problems. They don’t move with the timber and we normally remove them.
The most common problems we see are:
- Gaps round a timber door in stone or brick
- Window mastic to renew ahead of painting
- Weathered mastic on the most exposed windows
- Modern sealant on a period surround
For an older house near a landmark such as The Parish Church of All Saints, the joint between an old wall and a newer frame is generally the first place rain gets in.

Sand mastic in Mountfield: local notes
With historic houses such as Durhamford Manor (about 2 miles east) nearby, there’s older building stock in the area around Mountfield as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Robertsbridge station change hands often, and any sash windows need sound mastic to keep draughts and rain out. For site and facilities teams at buildings such as Vinehall School, the mastic around its windows and doors needs looking after like any other building’s.

Aftercare tips
So the new joints stay in good condition:
- Inspect the joints round the windows every year or so
- Find out about consent before window work on a listed home
- Take care around the mastic when scraping paint
- Avoid patching sand mastic with silicone
Leave the new mastic unpainted, which is the traditional advice. Ask us before any decorating around it.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.
Questions from Mountfield
Do you work for landlords with property near Robertsbridge station?
Yes, we work for landlords and agents. Just call 0345 464 0079 or drop us an email and tell us about the property, and we’ll send you a clear quote.
Can you do sand mastic in Mountfield?
Yes. We work across London and the South East, and Mountfield is part of that. Just call 0345 464 0079 or email us with a few details of the job.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Can you match the sealant colour?
We help you choose a colour that suits, from white and clear to greys and other shades. The product needed can limit the range.
How long will you be here?
It depends on the size of the job, but most jobs take a few hours per window, depending on the condition of the joints. We’ll tell you when we quote.
Will the old sealant be removed?
Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.
Can you replace silicone on a period window with sand mastic?
Yes, it’s a common request. The old silicone has to come out completely so the mastic beds in well.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
