About our window mastic in Sutton at Hone

Every window and door frame has a gap around it, and mastic is what closes it. When it cracks, hardens or pulls away, draughts and rain get in. The old mastic is removed and the joint resealed with a flexible exterior sealant. We work on aluminium frames, patio & French doors and timber windows & doors, and common reasons people get in touch are rain getting in at the frame or under the sill and draughts coming in around windows and doors.

Outdoor sealant needs dry, clean surfaces, so work on frames around Sutton at Hone is planned for dry weather. Let us know about access to all the frames, upstairs ones included.

Our work is backed for twelve months, and the guarantee is the same wherever you are.

Leave it or put it right?

Resealing frames is a short job: it takes a few hours for a few frames, or a day or more for a whole house. Wait for damp to appear and there may be plaster and decorating to sort out too. In a small place like Sutton at Hone, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.

Different surfaces, different methods

Timber windows & doors

Timber moves with moisture as well as heat, so a flexible sealant is essential. We seal onto sound, dry paintwork or timber.

Patio & French doors

Door frames take knocks and movement every time the doors are used. The sealant must cope with it.

Sutton at Hone homes and the weather

The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Lullingstone Castle (about 3.9 miles south-west) nearby, there’s older building stock in the area around Sutton at Hone as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.

For site and facilities teams at buildings such as Sutton-At-Hone Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s. In the older streets around Church of St John the Baptist, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For landlords with property near Farningham Road station, renewing tired window mastic between tenants heads off draught and damp complaints.

Aftercare tips

A little care helps the new joints last. We recommend:

  • Wipe condensation off the frames
  • Repaint timber before it’s bare
  • Keep solvents and bleach off the sealant
  • Make sure the drainage slots are not blocked

On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.

Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. A new joint closes it up.

When something else is needed

We will not take on work that will not last, so these are the limits:

  • Faulty window hardware
  • Misting between the panes of a double-glazed unit (that needs a new unit)
  • Draughts through the window seals rather than the frame

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

Joints and surfaces we work on

  • Aluminium frames
  • Composite doors
  • Patio & French doors
