When to call us in Tide Mills
Some old mastic was never deep enough. Mastic that is too thin cracks and drops out so we make sure the new mastic is the right thickness.
It’s worth asking for a quote if you see:
- Cracked mastic round a front door frame
- Draughty sash windows at the surround
- Mastic dropping out of the joint
- A silicone bead on a sash window that spoils the look
If you let a flat or house near Bishopstone (Sussex) station, any sash windows need sound mastic to keep draughts and rain out.
What to look for in a quote
- The length of the guarantee
- When the joint can take water or movement
- Are they insured?
- Whether all the old sealant comes out first
Sand mastic in Tide Mills
A silicone bead around a sash window can look out of place and does not suit the building. Sand mastic gives a finish that matches the age of the house, and we can replace one with the other. We work on stone surrounds, brick reveals and tenement windows, and the jobs we see most are draughty sash windows at the surround and mastic that needs renewing before redecorating.
Homes in small places like Tide Mills 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.
Every job comes with our 12-month guarantee, wherever you are in East Sussex.

Common questions in Tide Mills
Is Tide Mills within the area you cover?
Yes, Tide Mills is covered. Our work covers 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 Bishopstone (Sussex) station?
Yes. We work for landlords and agents as well as homeowners, and several properties can go on one quote. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.
Can you work on commercial sites?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
Is consent needed for window work on a listed home?
Check with your local planning authority. They’ll tell you if consent is needed for work to your windows.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Can I choose the sealant colour?
In most cases you can choose. We will explain which colours are available and agree one before any work starts.
Can sand mastic be painted?
It’s traditionally left unpainted, which is what traditional guidance recommends. Talk to us before any painting near it.
Can old silicone round a sash window be swapped for sand mastic?
Usually, yes. With the silicone removed and the joint cleaned, sand mastic is applied by hand.
How it works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for a single window, longer for several, and the area is left clean. Somewhere as small as Tide Mills, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.

What affects the quote in Tide Mills
Every job gets its own quote. These are the things that affect it:
- How much old sealant there is and how hard it is to remove
- Whether the work is at height
- When we can work, for business premises
- How many rooms, windows or areas are involved
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.
Helping us quote
To make quoting easier, let us know:
- Photos by email, if that is easy
- Any access issues, like height or stairs
- Roughly how big the job is
- If it’s domestic, commercial or a hotel
Call for a quick quote, or email us if that’s easier. Describe what needs sealing and we’ll explain what’s involved before giving you a price.
Why it’s worth doing now in Tide Mills
If you are redecorating, renew the mastic first. Paint over cracked mastic won’t stop the gaps, and the new mastic is traditionally left unpainted. Around Tide Mills, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
What you get with us
- Full insurance on every job
- Anti-fungal sanitary silicone in wet areas
- ARBOMaster approved applicator
- Every job guaranteed for a year
Landlords, agents and businesses in Tide Mills
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
Landlords and letting agents in Tide Mills can book us as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.
DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.

Sand mastic in Tide Mills: local notes
Tide Mills is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Historic houses like Alfriston Clergy House (about 4.1 miles north-east) are a reminder that the area around Tide Mills has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
If you live in an older home near Church of St Andrew, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you look after a building such as UTC@Harbourside, larger buildings have plenty of frames, and the mastic around each one ages.
