Sand mastic in Fishbourne, done properly
On many period windows, sand mastic looks right and suits the building. Newer frames usually get a flexible sealant instead and we’ll explain which is best for yours. We work on period & listed homes, sash and case windows and timber door frames, and the jobs we see most are gaps where the frame meets the masonry and cement or filler used on old window joints that has cracked.
Homes around Fishbourne range from older properties to newer houses, and their windows range just as widely. Each frame material needs the right sealant against the right wall.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Leave the new mastic unpainted
- Keep modern sealant off the mastic
- Get any rot dealt with first
- Go gently near the mastic when preparing windows
Don’t run silicone over the new mastic. If you see a crack, ask us to take a look before trying a quick fix.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry so early renewal protects both.

Fishbourne: your questions answered
Can you help a landlord with a rental near Fishbourne station?

Do you cover smaller places like Fishbourne?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you replace silicone on a period window with sand mastic?
Normally, yes. Once the silicone is out and the joint prepared we point it with sand mastic.
Can sand mastic be painted?
The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we will advise.
What guarantee comes with the work?
All our work has a 12-month guarantee.
How long does sand mastic take to harden?
Not straight away. The skin forms first, and the full set comes later and we will give you an idea for your job.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Can you do several jobs on one visit?
Yes. Several rooms, windows or areas can go on one quote.
Common problems we fix in Fishbourne
Age is the main cause. Even well-laid mastic needs renewing in time, depending on exposure and upkeep.
Any of these means the joints need attention:
- Wind and rain getting in round a sash window
- Mastic that needs renewing before redecorating
- Weathered mastic on the most exposed windows
- Gaps between timber frames and stone or brick
In the older streets around Church of St Peter and St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
What your quote should include
- Whether they’re fully insured
- Whether VAT is included
- Whether all the old sealant comes out first
- What happens if they find a problem under the old sealant
Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
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.
What affects the cost of sand mastic
Your quote is based on your job. We take into account:
- Access and height
- Mould in or behind the old joints
- Whether old sealant or filler has to be cut out
- Which sealant suits the joint
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, phone 0345 464 0079 or email us and we’ll give you an honest view and a quote.
What to tell us for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- How many joints, rooms or windows are involved
- A few photos by email, if you can
- Whether it’s a home or a business
- Whether it has been sealed before
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.
Landlord and commercial work in Fishbourne
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
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.
The process
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours for a single window, longer for several. In a smaller place like Fishbourne, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- First, we look at the surrounds with you and agree what needs doing.
- We rake out the old mastic and clean the joint.
- Deep voids are packed so the mastic is the right thickness.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- We dress the surface so it sits neatly against the masonry.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Tell us about any previous sealing or DIY attempts
- Let us know about stairs, lifts or work at height

Sand mastic in Fishbourne: local notes
Fishbourne is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For landlords with property near Fishbourne station, any sash windows need sound mastic to keep draughts and rain out. Managing a site like Fishbourne CofE Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.
