Frames and glazing around Crossbush
Crossbush 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. That is hard on the mastic around window and door frames, especially on the side facing the sea. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around The Parish Church of St Mary Magdalen, the joint between an old wall and a newer frame is generally the first place rain gets in. For landlords with property near Arundel station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Window mastic for homes and businesses in Crossbush
If you can feel air around a shut window, the gap is often at the frame. Resealing that joint can make a room feel noticeably less draughty. If the draught is through the window seals instead, we’ll tell you. We’re often asked to deal with cracked sealant at the sill ends and cracked internal joints between frame and plaster, across aluminium frames, uPVC windows and timber windows & doors.
Homes in small places like Crossbush often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

Questions from Crossbush
Does the coastal weather in Crossbush affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Will you come out to Crossbush?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us and we’re fully insured.
Can you do the inside joint as well?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We can do either or both.
How long does it take to reseal the windows on a house?
Allow a few hours for a few frames, or a day or more for a whole house. Access and the amount of old mastic make the biggest difference.
Can tenants book the work?
We are happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Is it OK to seal over old sealant?
No, because it fails. We remove every bit of old sealant first, so the new sealant bonds properly.

What else we do in Crossbush
Landlords, agents and businesses in Crossbush
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together.
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
When to call us in Crossbush
Timber windows bring their own problems. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
Any of these means the joints need attention:
- Rushed sealant from a window installation
- Whistling draughts around closed windows
- Cracked sealant at the sill ends
- Cracked internal joints between frame and plaster
For site and facilities teams at buildings such as The Littlehampton Academy, its window and door frames need their mastic kept sound, just like a home’s.

Leave it or put it right?
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 Crossbush can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not guesswork. That is why we ask about the job first and give you a clear quote before we start.

Should I try it myself first?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

Surface by surface
uPVC windows
The frame is cleaned with a product that won’t harm the plastic, then the new bead is laid against the frame and the wall.
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A tidy bead in anthracite grey, black or a matching colour suits the frame.
What we do, step by step
We keep the work tidy and contained to the joints we’re treating. The job generally takes a morning for a couple of windows and a door, and we tell you how long to leave it before we go. Somewhere like Crossbush 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.
- First we look at every frame and agree the list.
- The old mastic is cut out and the surfaces cleaned back.

- Finally we tidy up and check each joint.
