About our sand mastic in Nettlebed
A silicone bead around a sash window can look out of place and doesn’t suit the building. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. If you have crumbling sand mastic round a window and draughty sash windows at the surround, we can help.
Homes in small places like Nettlebed 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.
Big or small, it’s backed by our one-year guarantee.

Common questions in Nettlebed
Is sand mastic in Nettlebed guaranteed?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Do you cover Nettlebed for sand mastic?
Yes, Nettlebed is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we will send you a clear quote.
Is it possible to take out silicone and use sand mastic instead?
Yes, it’s a common request. The old silicone has to come out completely so the mastic beds in well.
Will there be a smell?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us, and we’re fully insured.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Honest limits
In fairness, there are a few things sealant won’t fix:
- Rotten sashes, sills or window boxes (a joiner’s job)
- Cracked or broken glass
- Decisions on consent for listed homes
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly.

Sand mastic in Nettlebed: local notes
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Greys Court (about 2.7 miles south-east) nearby, there’s older building stock in the area around Nettlebed 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.
Schools such as Nettlebed Community School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as Church of St Bartholomew, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Nettlebed is about 7 miles north of Caversham, in Oxfordshire. Anywhere in RG9, we cover sand mastic for homes and businesses. Our area takes in 443 places across Oxfordshire, from the larger towns to small villages. We also work in Reading, about 9 miles from Nettlebed.
All of RG9 is within our area for sand mastic. If you need sand mastic at a property on The Ridgeway, Wanbourne Lane and Watlington Street or a nearby road, our applicators can take on the job.

What else we do in Nettlebed
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Check with your local planning authority if your home is listed
- Inspect the joints round the windows every year or so
- Take care around the mastic when scraping paint
- Keep modern sealant off the mastic
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.
Leave it or put it right?
Cement-based fillers and modern sealants don’t always suit a period surround. Sand mastic is the like-for-like choice, which can matter on listed and conservation-area homes. Around Nettlebed, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before work begins.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
How it works
At the end, we look at the finished work together and explain the cure time. The work normally takes anything from a few hours to a full day, depending on how many windows, depending on the size of the job. In a small place like Nettlebed, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we look at the surrounds with you and agree what needs doing.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic isn’t too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.
Preparing for the visit
- On commercial sites, let us know about site rules
- Keep children and pets away from the work area
- For indoor joints, keep the area dry beforehand if you can
