Window mastic in Chessington

Homes in Chessington have every kind of window: uPVC, aluminium, timber and composite, plus patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. We work on uPVC windows, aluminium frames and window sills, and people most often call us about mastic that has split away from the wall and untidy mastic left by window fitters.

London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. The mastic around them dries out and cracks with age, which is when draughts and damp patches appear in homes in Chessington.

The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

Why act early in Chessington

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. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler.

There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

How the job changes by surface

Composite doors

If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We seal the frame and let you know about anything else.

Aluminium frames

Aluminium needs a sealant that bonds to coated metal, and acetoxy silicones aren’t used, as they can attack some metals. We use a neutral-cure product.

Frames and glazing around Chessington

Historic houses like Fitznells Manor (about 2.2 miles east) are a reminder that the area around Chessington 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. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

In the older streets around Church of St Mary the Virgin, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Letting a property close to Chessington North station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

What we’re called out for in Chessington

Some failures date back to when the windows were fitted. Mastic laid onto dusty, damp or crumbling surfaces never bonded as it should, and it lets go sooner than it should.

Signs it’s time to call us include:

  • Untidy mastic left by window fitters
  • Sealant in the wrong colour for the frame
  • Leaking joints at the ends of sills
  • Hard, cracked sealant around windows

For site and facilities teams at buildings such as Castle Hill Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Choosing a sealant specialist

Should I try it myself first?

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.

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

Keeping the joints in good condition

So the new joints stay in good condition:

  • Do not paint over the silicone
  • Avoid blasting the frames with a pressure washer
  • Do not use solvent cleaners on the joint
  • Walk round the house once a year and look at the joints

Timber frames need their paint kept up, because bare, wet timber moves more and pulls at the joint. Paint up to the joint, not over the silicone.

On timber windows, water behind the joint can lead to rot. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.

You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.

Which products do you use?

It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
