Trusted window mastic in Beckley Furnace

How we handle window mastic in Beckley Furnace

The new joint doesn’t have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the line suits the frame instead of standing out. We work on patio & French doors, composite doors and timber windows & doors, and the jobs we see most are draughty joints inside around the window and sealant in the wrong colour for the frame.

Around Beckley Furnace, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.

We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Honest limits

New sealant can’t fix everything, and we will tell you before we start. Sealant won’t put right:

  • 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)
  • Worn gaskets, brush seals or a door that has dropped

If you are not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer.

The process

The work is kept neat and contained to the joints we’re treating. The job normally takes anything from an hour or two to a full day, depending on how many frames there are. In a small place like Beckley Furnace, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We check how each frame can be reached safely.
  2. Old, cracked mastic is removed completely.
  3. Frame and wall are cleaned and must be dry before sealing.
  4. Backing rod fills deep voids and the sealant goes in on top.
  5. The joint is shaped to shed water and the area tidied.

Before we arrive

  • Mention any sign-in or site rules at work premises
  • Tell us about any water getting in
  • Let us know about earlier repairs to the joints

Landlord and commercial work in Beckley Furnace

For anyone letting property in or around Beckley Furnace, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs.

Landlords and agents in Beckley Furnace can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.

Why deal with it now?

Failed mastic is not a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. If we find failed glass units or worn seals, we’ll tell you. Older cottages and farmhouses around Beckley Furnace can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, phone 0345 464 0079 or email us for an honest opinion and a quote.

  • You choose the colour before work begins

Take a look at what affects the cost or what customers say.

Can I do it myself?

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Surface by surface

Patio & French doors

Water at the foot of a door frame is not always the mastic: blocked drain slots, worn brush seals and threshold details can let water in too. We look for the cause first.

Window sills

Every drop off the glass ends up on the sill, so the joints at each end and underneath matter. Each is cleaned out and resealed.

How we quote for window mastic

Some jobs are bigger than they look, and some smaller. The main factors:

  • The old material and how stubborn it is

  • The amount of work

Asking for a quote

Before you ask for a quote, have a think about:

  • The rough size of the job
  • How we’d reach the joints
  • The type of property
  • What the problem is, such as mould, gaps, leaks or cracking

A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email pictures if that’s easy.

What window mastic looks like in Beckley Furnace

In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. 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.

Great Dixter, about 2.7 miles north, is one of the historic houses in the wider area around Beckley Furnace, and older homes nearby need a sealant that suits their walls.
