Window Mastic in Whatlington
Window and door frames in Whatlington need attention? We cut out the old, prepare the joints and apply the right sealant, with a 12-month guarantee.
- Old mastic that has gone black or come away
- Draughty joints inside around the window
- A bead that does not match the frame
Window mastic in Whatlington
Every window and door frame has a gap around it, and mastic is what closes it. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. We work on patio & French doors, uPVC windows and aluminium frames, and people most often call us about rain getting in at the frame or under the sill and sealant in the wrong colour for the frame.
Mastic can only go onto a dry, clean joint, so window work in Whatlington is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Big or small, it’s backed by our one-year guarantee in Whatlington and across East Sussex.

The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a morning for a couple of windows and a door. Somewhere like Whatlington needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.
- We fit backing rod in deep gaps so the sealant is the right 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
- Tell us about access, such as stairs, a lift or high-level joints
- For business premises, tell us about site rules or sign-in

Advice
When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- A door that needs adjusting, rehanging or new seals
- Damp coming through the wall itself rather than the frame joint
- A failed sealed unit that has misted up
If you’re not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer before booking.
Joints and surfaces we work on

What window mastic looks like in Whatlington
With historic houses such as Durhamford Manor (about 0.6 miles east) nearby, there’s older building stock in the area around Whatlington as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. 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.
If you let a flat or house near Battle station, renewing tired window mastic between tenants heads off draught and damp complaints. Schools such as Vinehall School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Why it’s worth doing now in Whatlington
Choosing the product is half the job. Decorators’ caulk and bathroom silicone are not designed for outside joints that move. An exterior, low-modulus sealant stays flexible in sun and frost. In a small place like Whatlington, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

Common questions in Whatlington
Will you come out to Whatlington?
Yes. Whatlington is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you do window mastic in Whatlington?
Yes. Our work covers London and the South East, and Whatlington is part of that. You can ring 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll send you a clear quote.
What do you need from me for a quote?
A short description and the location, with photos by email if possible. We will ask anything else we need to know.
Do you remove the old sealant?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Can you seal the gap between the frame and the plaster indoors?
Yes. Plenty of draughts come through the inside joint as well as the outside, so sealing both is often worthwhile.
Where do you work from?
We’re based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
How many windows can you do in a day?
The work takes a few hours for a few frames, or a day or more for a whole house. Access and how stubborn the old mastic is affect the time most.
Is the work guaranteed?
Yes. Our 12-month guarantee covers every job.
Aftercare tips
So the new joints stay in good condition:
- Clean frames with a soft cloth and soapy water
- Do not aim a pressure washer at the joints
- Keep drainage slots and sill grooves clear
- Wipe condensation off the frames
Most silicone sealants won’t take paint, so if you’re planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. Resealing closes it.
What we are called out for in Whatlington
Sun, frost and rain wear sealant out. UV light hardens the outside of the bead, until it loses its stretch and starts to crack.
If you can see any of these, it’s time to have the joints looked at:
- White mastic on grey or black frames
- Rushed sealant from a window installation
- Old mastic that has gone black or come away
- Cracked or shrunken mastic around the frame
Homes close to St Mary Magdalene's Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
