Window mastic for homes and businesses in Slutshole
Frames and walls do not move together. Heat and cold make frames grow and shrink against brick or render that hardly moves. So the sealant has to stretch and recover, which is why we use a low-modulus product. If you are dealing with old mastic that has gone black or come away and a bead that doesn’t match the frame, we can help, whatever the surface.
In a village or hamlet like Slutshole, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Big or small, you get the same 12-month guarantee in Slutshole and across Kent.

When it isn’t the sealant
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Faulty window hardware
- Soft or decayed wood in the frame
- Damp problems in the wall away from the window
If you are not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer.
Surfaces we seal
- Window sills
- uPVC windows

How we quote for window mastic
The price is agreed before any work begins. It takes into account:
- Which sealant suits the joint
- How many rooms, windows or areas are involved
- Working hours on commercial sites
- Access and height
Leaving a failed joint generally makes the job bigger, not smaller. If you are unsure, phone 0345 464 0079 or drop us an email and we will give you an honest view and a quote.
Asking for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Whether it has been sealed before
- A few pictures by email, if you can
- Any access issues, like height or stairs
- If it’s domestic, commercial or a hotel
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email pictures if that is easy.
The process
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. It normally takes a few hours for a few frames, or a day or more for a whole house. In a small place like Slutshole, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away, along with any loose debris.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- Keep children and pets away from the work area
- Let us know if you’ve seen damp or leaks
- Clear the area around the work

For landlords and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
Different surfaces, different methods
Window sills
Every drop off the glass ends up on the sill, so the joints at each end and underneath matter. Each is cleaned out and resealed.
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the threshold joint takes a lot of water. We prepare and reseal every joint, backing the deep ones.
Frames and glazing around Slutshole
Slutshole is within about 3 miles 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. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For site and facilities teams at buildings such as Hernhill Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s. Homes close to Church of St Michael include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For landlords with property near Selling station, renewing tired window mastic between tenants heads off draught and damp complaints.

Looking after it afterwards
So the new joints stay in good condition:
- Air rooms to keep condensation down around windows
- Make sure the drainage slots are not blocked
- Paint up to the joint, not over it
- Do not use solvent cleaners on the joint
Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.
Leaks usually 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.
DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

What else we do in Slutshole
Slutshole: your questions answered
Is window mastic in a coastal place like Slutshole any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Can you help a landlord with a rental near Selling station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can ring 0345 464 0079 or email us with the details for a clear quote.
Is the work guaranteed?
Yes. Each job is covered for 12 months.
Do I have to be there?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.

Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Do you cover Slutshole?
Yes. We’re based in Crawley and work across South East England, London and Scotland, and that includes Slutshole.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Will new mastic stop draughts?
If the draught is coming in around the frame, yes. If it’s coming through the window seals, we’ll tell you.
