About our window mastic in Twitham

There are two joints on most windows. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. Either or both can be done. We’re often asked to deal with mastic that has split away from the wall and mastic that’s falling out in pieces, on patio & French doors, timber windows & doors and uPVC windows.

Somewhere as small as Twitham, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.

We stand behind the work with a 12-month guarantee, so you are covered after we have gone.

Should I try it myself first?

Some sealant jobs are within reach of a careful DIYer, 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.

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

What we can’t put right

We’ll always be straight with you, so here’s what sealant cannot fix:

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

If you’re not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.

What we seal

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

What we’re called out for in Twitham

Sun, frost and rain wear sealant out. UV light hardens the outside of the bead, until it loses its stretch and starts to crack.

Signs it’s time to call us include:

  • Gaps between the frame and the inside reveal
  • Whistling draughts around closed windows
  • Hard, cracked sealant around windows
  • Untidy mastic left by window fitters

In the older streets around Church of St James, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

10 questions to ask before booking

Surface by surface

Window sills

The end joints of a sill tend to fail before the rest. We reseal them so rain cannot run into the wall.

Aluminium frames

Aluminium moves with heat, and the frames are often slimmer than uPVC. A neat, narrow bead in a colour to match keeps the clean look.

Your questions about window mastic in Twitham

Can you help a landlord with a rental near Adisham station?

Yes, we work for landlords and letting agents. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.

Do you cover smaller places like Twitham?

Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

Do you have insurance?

Yes. We’re fully insured.

Do I need to be at home?

For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.

Can new window sealant be painted?

Most silicone can’t be painted. Let us know beforehand, and we’ll use a paintable product where it suits.

Is the work guaranteed?

Yes. Each job is covered for 12 months, inside or out.

What should I tell you?

Let us know what needs doing and where. If we need more, we will ask.

How many windows can you do in a day?

Allow a few hours for a few frames, or a day or more for a whole house. Access and how stubborn the old mastic is affect the time most.

Twitham homes and the weather

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. With historic houses such as Goodnestone Park (about 1.6 miles south) nearby, there’s older building stock in the area around Twitham as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.

For landlords with property near Adisham station, renewing tired window mastic between tenants heads off draught and damp complaints.

Landlord and commercial work in Twitham

Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.

We also work for property managers and facilities teams. Several sites can be quoted together, and we are fully insured for the work.

What affects the cost of window mastic

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

  • Working hours on commercial sites
  • Which sealant suits the joint
  • How many rooms, windows or areas are involved
  • The amount of work

Instead of a standard rate, 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.

What to tell us for a quote

When you contact us, these details help:

  • If someone has resealed it before
  • Pictures of the joints, sent by email
  • How many joints, rooms or windows are involved
  • If it’s domestic, commercial or a hotel

A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.

The process

There’s no need to move everything out, just the space around the work. We protect the rest, and the work takes a few hours for a handful of frames, longer for a whole house in most cases. Somewhere as small as Twitham, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First, we confirm safe access to each frame.
  2. All the failed sealant is cut away, along with any loose debris.
  3. Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
  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.

Preparing for the visit

  • Try not to wet indoor joints just before the visit
  • Mention any tricky access
  • Mention any sign-in or site rules at work premises
