About our window mastic in Warningcamp
Most frames have an outside joint and an inside one. Outside, the mastic keeps rain out; inside, the joint between frame and plaster stops draughts and tidies the reveal. We seal one or both, depending on what’s needed. If you have mastic that’s falling out in pieces and mastic that has split away from the wall, we can put it right.
Around Warningcamp, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
You are covered for a year from the day we finish. If anything isn’t right with it, phone 0345 464 0079 or send us an email.

The process
You do not need to clear the whole room or building, just the space around the work. We protect the rest, and the work takes most of a day for a typical house, less for a few frames for a typical job. For a village or hamlet like Warningcamp, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Getting ready for the visit
- Tell us if parking is tricky

Common problems we fix in Warningcamp
On timber frames, paint and putty build up around the joint. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
Look out for any of the following:
- Leaking joints at the ends of sills
- Damp patches on the reveal after heavy rain
- Whistling draughts around closed windows
- Cracked internal joints between frame and plaster
Letting a property close to Arundel station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
Questions to ask before booking
- How the joint is cleaned and prepared
- Which sealant they’ll use, and why
- When the joint can take water or movement
- Whether they seal over old material or remove it
DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

- Any working-time requirements on site
- How many rooms, windows or areas are involved
Combining jobs into one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will give you a clear quote for the lot.

How the job changes by surface
Composite doors
Front doors take the weather head on, and the top and bottom corners tend to fail first. We pay most attention there.
Window sills
Where a sill meets brick or render, the ends often crack first. We reseal them so rain cannot run into the wall.

Your questions about window mastic in Warningcamp
Can you help a landlord with a rental near Arundel station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.
Will you come out to Warningcamp?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
How long before the joint can be used?
Cure times vary by product and the temperature. We tell you how long to leave it before we go.
What should I tell you?
A short description and the location, with photos by email if possible. If we need more, we’ll ask.
Do you seal inside as well as outside?
Yes. Draughts often come through the inside gap too, so it can be worth sealing both.
Will resealing my frames help with draughts?
If the draught is coming in around the frame, yes. If it’s coming through the window seals, we’ll tell you.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.

Window mastic in Warningcamp: local notes
With historic houses such as Ecclesden Manor (about 2.8 miles south-east) nearby, there’s older building stock in the area around Warningcamp as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you look after a building such as The Littlehampton Academy, its window and door frames need their mastic kept sound, just like a home’s. Historic houses such as Ecclesden Manor, about 2.8 miles south-east, show how far back building around Warningcamp goes, and older homes nearby need a sealant that suits their walls.

What’s near Warningcamp
For rail, the closest station is Arundel station, roughly 1 mile west of the centre. Nearby you will also find Arundel and District Hospital (1.8 miles west) and Lyminster Siege Castle (0.6 miles west). Green spaces nearby include WWT Arundel and Highdown Hill.
Why deal with it now?
Not every sealant suits a window. Interior caulk and bathroom silicone aren’t made for exterior frame joints. An exterior, low-modulus sealant stays flexible in sun and frost. Where a wall is exposed, as many are in small places like Warningcamp, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.
