Window mastic in Paddlesworth, done properly

Behind a thin line of old mastic there’s sometimes a deep void. Filling it with sealant alone leaves a joint that can’t move properly, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. If you have cracked sealant at the sill ends and sealant in the wrong colour for the frame, we can put it right, on timber windows & doors, composite doors and aluminium frames alike.

Mastic can only go onto a dry, clean joint, so window work in Paddlesworth is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.

All of our work is guaranteed for twelve months, in Paddlesworth and everywhere else we cover.

Leave it or put it right?

The work is quick compared with the damage it prevents: it takes anything from an hour or two to a full day, depending on how many frames there are. Leave it until water is coming in and you may need plastering and decorating as well. Older cottages and farmhouses around Paddlesworth can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.

Surface by surface

Window sills

Every drop off the glass ends up on the sill, so the sill ends and the joint under the frame are vital. They’re cut out and resealed with exterior sealant.

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.

When something else is needed

Before you book, it’s worth knowing the limits too:

  • Soft or decayed wood in the frame
  • A failed sealed unit that has misted up
  • Broken hinges, locks or handles

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

Joints and surfaces we work on

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

Frames and glazing around Paddlesworth

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. With historic houses such as Starkey Castle (about 2.8 miles north-east) nearby, there’s older building stock in the area around Paddlesworth as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.

Rented homes near Snodland 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. Schools such as Snodland CofE Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around St Benedict's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What happens on the day

Before we leave, we go over the finished joints with you. The work normally takes most of a day for a typical house, less for a few frames, depending on the size of the job. For a village or hamlet like Paddlesworth, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. First, we confirm safe access to each frame.
  2. Old, cracked mastic is removed completely.
  3. The surfaces are cleaned and left dry.
  4. Deep voids are backed, then the sealant is gunned in.
  5. We tool the joint so water runs off, then clear up.

Before we arrive

  • Move anything stored near the joints
  • Try not to wet indoor joints just before the visit
  • Tell us about access, such as stairs, a lift or high-level joints

Advice

Paddlesworth questions

I let a flat near Snodland station. Can you help?

Yes. We work for landlords and agents as well as homeowners. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.

Can you do window mastic in Paddlesworth?

Yes. We work across London and the South East, and Paddlesworth is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job.

Do you guarantee window mastic?

Yes. All our work carries a 12-month guarantee, and we are ARBOMaster approved applicators.

Can you seal the gap between the frame and the plaster indoors?

Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We do one or both.

What sealant do you use?

Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.

Where do you work from?

Mr Mastic is based in Crawley. Our applicators cover Paddlesworth, along with the rest of our area.

Can you seal over the old sealant?

No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.

Will the old sealant be removed?

Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.

Looking after it afterwards

Once the sealant has cured, a few habits help it last:

  • Keep timber frames painted
  • Paint up to the joint, not over it
  • Wipe condensation off the frames
  • Keep drainage slots and sill grooves clear

Most silicone sealants will not take paint, so mention any painting plans before we start. There are paintable sealants for joints that need it.

Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.
