Common questions in Tide Mills
Does the coastal weather in Tide Mills affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Do you work for landlords with property near Bishopstone (Sussex) station?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can go on one quote. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll send you a clear quote.
Will resealing my frames help with draughts?
Yes, where the draught is at the frame edge. We check where the draught is before work begins.
Do you cover Tide Mills?
Yes, we do. Our applicators work in Tide Mills.
Are you fully insured?
Yes, we’re fully insured for every job we do.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used before we leave.
Can I add another job to the visit?
Yes, we can. More than one area can be quoted together.
Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected.

What else we do in Tide Mills
When it isn’t the sealant
In fairness, there are a few things sealant won’t fix:
- Condensation trapped between the panes
- Damp coming through the wall itself rather than the frame joint
- Rotten timber, which needs a joiner first
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly.
What we seal
- Timber windows & doors
- Aluminium frames
- uPVC windows
- Composite doors
- Window sills
- Patio & French doors
When to call us in Tide Mills
Water runs down the glass onto the sill, and the ends of the sill, where it meets the wall, are where it gets in. Failed sealant there lets rain into the wall or behind the frame.
People normally contact us when they notice one of these:
- Mastic that has split away from the wall
- Untidy mastic left by window fitters
- Whistling draughts around closed windows
- Old mastic that has gone black or come away
Homes close to Church of St Andrew include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Different surfaces, different methods
Window sills
The end joints of a sill tend to fail before the rest. We reseal them so rain cannot run into the wall.
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A neat, narrow bead in a colour to match keeps the clean look.
Landlord and commercial work in Tide Mills
Letting agents often deal with us directly. Tell us the address, the job and how access works and we will quote.
If you manage several properties in or around Tide Mills, jobs at different addresses can go on one quote. Just tell us the addresses and what each one needs.
How it works
At the end, we look at the finished work together and explain the cure time. The work normally takes a few hours for a handful of frames, longer for a whole house, depending on the size of the job. In a small place like Tide Mills, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check each frame and agree which ones need doing.
- The old mastic is cut out and the surfaces cleaned back.
- Deep gaps are filled with backing rod to set the depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
How to prepare
- Let us know about parking restrictions
- Let us know about earlier repairs to the joints
- Move anything stored near the joints
Ask for a quote
Getting a quote is simple: let us know what needs doing and where, and roughly how big it is. A few pictures by email make the job easier to understand, and we will come back to you with a quote.
Related advice
Why act early in Tide Mills
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. Resealing now is a small job by comparison. Older cottages and farmhouses around Tide Mills can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting. If you are unsure, call 0345 464 0079 or send us an email for an honest opinion and a quote.

Frames and glazing around Tide Mills
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 window and door frames, which can dry out and crack sooner where a building faces the weather. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you look after a building such as UTC@Harbourside, its window and door frames need their mastic kept sound, just like a home’s. Letting a property close to Bishopstone (Sussex) station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

A little further out are Arlington Castle (4.8 miles north-east) and Chailey Heritage Marine Hospital (less than half a mile south-west). For a walk, there’s Itford Hill.
Looking after it afterwards
Looking after new joints is easy:
- Avoid blasting the frames with a pressure washer
- Keep paint off silicone joints
- Walk round the house once a year and look at the joints
- Use gentle cleaners on frames and sealant
Timber frames need their paint kept up, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.
Leaks normally show up in wet, windy weather, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.
