Questions from Holly Green
Do you cover smaller places like Holly Green?
Yes, Holly Green is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Princes Risborough station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear quote.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Can I paint the new mastic?
It’s traditionally left unpainted, which is what traditional guidance recommends. Ask us before decorating.
Can you work on commercial sites?
Yes. We’ve worked for hotels, offices and other businesses and we are fully insured.
Do you take out the old sealant first?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Sand mastic in Holly Green
Silicone on a period window often looks wrong and is not always the right material. Sand mastic is the traditional choice and we can swap the silicone for it. Typical jobs include gaps between timber frames and stone or brick and mastic dropping out of the joint, across brick reveals, period & listed homes and tenement windows.
Homes in small places like Holly Green often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
You get a 12-month guarantee, the same in Holly Green as everywhere else we work.

How the job changes by surface
Stone surrounds
Sand mastic sits naturally against stone. The finish blends with the masonry.
Timber door frames
Door frames get knocked and soaked and the mastic can crack early. It’s renewed by hand.
What happens on the day
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. Once we have agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours per window, depending on the condition of the joints. Somewhere like Holly Green needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

Related advice
Leave it or put it right?
Not every draught comes from the sashes themselves. Gaps between the frame and the wall can be just as bad and new mastic seals them. In a small place like Holly Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
We do not show prices on the website, because each job is priced on what it involves. For a quick quote, please ring 0345 464 0079 or send us an email and we will talk you through it.

How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Leave the new mastic unpainted
- Keep sills and gutters clear so water drains away
- Do not run silicone over sand mastic
- Check with your local planning authority if your home is listed
Do not run silicone over the new mastic. If anything cracks, get it looked at before trying a quick fix.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens as more mastic falls out.
Work for landlords, hotels and businesses
We work for landlords and agents as well as householders. Resealing between tenancies is a simple way to keep a property in good order.
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can go on one quote.

Holly Green homes and the weather
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In the older streets around Church of the Holy Trinity, the joint between an old wall and a newer frame is generally the first place rain gets in. If you look after a building such as Princes Risborough School, its window and door frames need their mastic kept sound, just like a home’s.

Shallow joints are a common cause. Mastic that is too thin cracks and drops out so we make sure the new mastic is the right thickness.
Any of these means the joints need attention:
- Open joints round the window box
- Weathered mastic on the most exposed windows
- Mastic that needs renewing before redecorating
- Crumbling sand mastic round a window
If you let a flat or house near Princes Risborough station, cracked sand mastic around sash windows lets in the draughts tenants complain about.
