Window mastic for Bidborough homes and businesses

Window mastic for homes and businesses in Bidborough

The mastic around a window or door seals the gap between the frame and the wall. When it cracks, hardens or pulls away, draughts and rain get in. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We work on window sills, timber windows & doors and aluminium frames, and people most often call us about a bead that doesn’t match the frame and rushed sealant from a window installation.

Somewhere as small as Bidborough, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.

Each job carries a 12-month guarantee, whatever its size.

Windows and doors in Bidborough

With historic houses such as Penshurst Place (about 2.3 miles west) nearby, there’s older building stock in the area around Bidborough as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

For an older house near a landmark such as Parish Church of St Lawrence, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Schools such as Southborough CofE Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Looking after it afterwards

How long the joints last depends on use and care. Here’s what we suggest:

  • Keep solvents and bleach off the sealant
  • Keep jet washers away from the mastic
  • Check the mastic once a year
  • Make sure the drainage slots are not blocked

Check the drainage slots in the frames aren’t blocked, so rain drains out rather than building up at the sealant.

Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.

Quotes for window mastic in Bidborough

You’ll get a clear quote before any work starts. It’s based on:

  • The old material and how stubborn it is
  • The size of the job
  • Any working-time requirements on site
  • Any mould that needs treating

Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will explain what it covers.

What to tell us for a quote

Photos by email are helpful but not essential. Try to tell us:

  • What’s wrong with the joints now
  • How we’d reach the joints
  • Photos by email, if that is easy
  • If it’s domestic, commercial or a hotel

Need a quote? Please call 0345 464 0079 or send us an email and tell us about the job. You will know what we plan to do, and what it will cost, before any work begins.

The process

When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes anything from an hour or two to a full day, depending on how many frames there are. In a small place like Bidborough, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We start by checking each window and door with you.
  2. Next the failed sealant is cut away and the joint cleaned.
  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

  • Mention any parking rules near the property
  • Keep pets and children clear of the area while we work
  • Try not to wet indoor joints just before the visit

What the job involves on each surface

Window sills

Masonry sills can have joints where water gets in, including the one between the sill and the frame above. Those are sealed with a product suited to stone or concrete.

uPVC windows

Plastic frames move a lot between a hot afternoon and a cold night, so the joint needs a low-modulus sealant that stays flexible. White is the usual colour, with brown, anthracite grey and black for coloured frames.

When it is not the sealant

New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:

  • A sash or casement that won’t close properly
  • Damp coming through the wall itself rather than the frame joint
  • Misting between the panes of a double-glazed unit (that needs a new unit)

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

Signs you need window mastic in Bidborough

A lot of older mastic was never designed to stay flexible. Once it’s rigid, every bit of frame movement pulls at it, and a gap opens along one edge.

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

  • Gaps between the frame and the inside reveal
  • Whistling draughts around closed windows
  • Cracked or shrunken mastic around the frame
  • Sealant in the wrong colour for the frame

Letting a property close to Leigh (Kent) station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
