West Blatchington homes and the weather
West Blatchington is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Historic houses like Preston Manor & Gardens (about 1.3 miles east) are a reminder that the area around West Blatchington has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Rented homes near Aldrington station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. For site and facilities teams at buildings such as Aldrington CofE Primary School, its window and door frames need their mastic kept sound, just like a home’s.

About our window mastic in West Blatchington
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. Common call-outs are for hard, cracked sealant around windows and whistling draughts around closed windows, across composite doors, patio & French doors and aluminium frames.
Homes around West Blatchington range from older properties to newer houses, and their windows range just as widely. Each frame material needs the right sealant against the right wall.

DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Questions from West Blatchington
Does living near the coast affect window mastic in West Blatchington?
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.
I let a flat near Aldrington station. Can you help?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Will there be a smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Can you work on commercial sites?
Yes, regularly. We can plan bigger jobs in stages.
What information do you need?
The location, the problem and the rough size of the job. Photos by email help too.
Can I paint over the new sealant?
Not if it’s silicone. Tell us your decorating plans and we’ll pick a sealant to suit.
Can resealing stop a draught around my window?
In many cases. The gap between frame and wall is a common source of draughts, and resealing inside and out closes it.
How do I get a quote for window mastic in West Blatchington?
Every job is different, so each one gets its own quote. For a quick quote, phone 0345 464 0079 or drop us an email and let us know what needs doing and where.
Do you need window mastic in West Blatchington?
Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the brick or render around it hardly moves. If the sealant cannot stretch, it splits.
The problems people generally mention when they call include:
- Cracked internal joints between frame and plaster
- Mastic that’s falling out in pieces
- Cold air getting in at the frame edge
- Cracked sealant at the sill ends
For an older house near a landmark such as St Peter's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

The process
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. It normally takes anything from an hour or two to a full day, depending on how many frames there are. Parking around West Blatchington is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- 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.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Finally we tidy up and check each joint.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Move anything stored near the joints
- Mention any parking rules near the property

Surface by surface
Window sills
Sills catch the water running down the glass, so the joints at each end and underneath matter. They’re cut out and resealed with exterior sealant.
Aluminium frames
Coated aluminium needs a compatible sealant, and acetoxy silicones are not used, as they can attack some metals. Neutral-cure sealant is the safe choice.
Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Air rooms to keep condensation down around windows
- Check the mastic once a year
- Keep drainage slots and sill grooves clear
- Paint up to the joint, not over it
Keep the new mastic undisturbed while it cures, for as long as we advise. Keep jet washers away from the frames.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
