About our window mastic in Little Braxted

Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that can’t flex, so deep gaps get backing rod first. That way the new bead bonds to the frame and the wall only. If you are dealing with water coming in at the bottom corners of a door and mastic that’s falling out in pieces, we can help, whatever the surface.

Homes in small places like Little Braxted 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.

The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or email us.

Should I try it myself first?

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

Aftercare tips

A little care helps the new joints last. Our advice:

  • Keep solvents and bleach off the sealant
  • Keep paint and stain on wooden frames in good order
  • Do not aim a pressure washer at the joints
  • Make sure the drainage slots aren’t blocked

Try not to touch the new joint while it cures, for as long as we advise. Keep jet washers away from the frames.

Leaks generally show up in wet, windy weather, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.

What sealant work can’t fix

Honest advice matters more to us than a booking, so here’s what sealant can’t fix:

  • Rotten timber, which needs a joiner first
  • A failed sealed unit that has misted up
  • Faulty window hardware

If you are not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer before you book.

What happens on the day

Before we leave, we go over the finished joints with you. The work normally takes a few hours for a few frames, or a day or more for a whole house, depending on the size of the job. For a village or hamlet like Little Braxted, the journey is planned in advance: 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.

  1. We check each frame and agree which ones need doing.
  2. The old mastic is cut out and the surfaces cleaned back.
  3. Where gaps are deep, backing rod goes in first.
  4. We apply a weatherproof sealant to match the frame and tool it neatly.
  5. Finally we tidy up and check each joint.

Preparing for the visit

  • Tell us if parking is tricky
  • Let us know about earlier repairs to the joints
  • Clear the area around the work

Advice

Frames and glazing around Little Braxted

London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

If you look after a building such as Maltings Academy, larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near Witham station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Little Braxted is about 1 mile east of Witham, in Essex. Anywhere in CM8, our applicators can take on window mastic. Little Braxted is one of 644 places in Essex where we work. For nearby work, see our Chelmsford page.

What the job involves on each surface

Window sills

Sills catch the water running down the glass, so the joints at each end and underneath matter. Each is cleaned out and resealed.

Composite doors

Front doors take the weather head on, and the top and bottom corners tend to fail first. We pay most attention there.

What happens if it’s left?

Choosing the product is half the job. Decorators’ caulk and bathroom silicone aren’t designed for outside joints that move. A low-modulus exterior sealant keeps its stretch through hot and cold weather. Where a wall is exposed, as many are in small places like Little Braxted, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

What it costs depends on the amount of work, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts.

Signs you need window mastic in Little Braxted

Some failures date back to when the windows were fitted. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, so it comes away long before its time.

If you can see any of these, it’s time to have the joints looked at:

  • Gaps where the sill meets the wall
  • Draughts coming in around windows and doors
  • Old mastic that has gone black or come away
  • Hard, cracked sealant around windows

For an older house near a landmark such as Church of St Nicholas, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What to look for in a quote

  • How the colour is chosen
  • Is the old sealant removed completely?
  • Whether the sealant suits the joint
  • What insurance they hold
