Trusted window mastic in Nevendon

Looking after it afterwards

After the cure time, these simple habits help:

  • Avoid harsh chemicals near the mastic
  • Avoid blasting the frames with a pressure washer
  • Check the mastic once a year
  • Do not paint over the silicone

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

A small gap around a frame only grows. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. A new joint closes it up.

When to call us in Nevendon

Sun, frost and rain wear sealant out. UV light hardens the outside of the bead, and over the years it loses its give, cracks and comes away.

Signs it’s time to call us include:

  • Rushed sealant from a window installation
  • Cracked sealant at the sill ends
  • Damp patches on the reveal after heavy rain
  • A bead that does not match the frame

Rented homes near Wickford 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.

What your quote should include

  • When the joint can take water or movement
  • Whether they seal over old material or remove it
  • Whether they’re fully insured
  • What guarantee comes with the work

Our hiring checklist

What the job involves on each surface

Patio & French doors

Heavy door frames can move more than windows. The sealant must cope with it, where a rigid one would crack.

Timber windows & doors

On period timber windows, traditional sand mastic is sometimes the better choice. We can talk through the options.

Why deal with it now?

Not every sealant suits a window. Decorators’ caulk and bathroom silicone aren’t designed for outside joints that move. An exterior, low-modulus sealant stays flexible in sun and frost. Older cottages and farmhouses around Nevendon can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and agree the price before starting.

What you get with us

  • Homes, businesses and hotels
  • We leave the area clean and tidy
  • Fully insured
  • White, clear, grey or another colour, product permitting

The process

When we arrive, we look over the joints with you first. Surfaces next to the work are protected before work begins. Most jobs take anything from an hour or two to a full day, depending on how many frames there are. For a village or hamlet like Nevendon, 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. First we look at every frame and agree the list.
  2. We remove the old mastic and clean the frame and the wall.
  3. We fit backing rod in deep gaps so the sealant is the right depth.
  4. New exterior sealant goes on in a matching colour and is tooled smooth.
  5. We clear up and check every joint is fully closed.

Getting ready for the visit

  • Mention any parking rules near the property
  • Tell us about any previous sealing or DIY attempts
  • Keep pets and children clear of the area while we work

What sealant work cannot fix

Honest advice matters more to us than a booking, so here’s what new sealant will not do:

  • Worn gaskets, brush seals or a door that has dropped
  • Penetrating damp from a failed cavity tray or render
  • Misting between the panes of a double-glazed unit (that needs a new unit)

If in doubt, phone 0345 464 0079 or send us an email and we will say what we think.

Joints and surfaces we work on

  • Aluminium frames
  • Timber windows & doors
  • Patio & French doors
  • uPVC windows
  • Window sills
  • Composite doors

Nevendon homes and the weather

London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Managing a site like Abacus Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. Homes close to Church of All Saints include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in.
