Trusted window mastic in Long Green

Window mastic in Long Green, done properly

There are two joints on most windows. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. We work on composite doors, timber windows & doors and aluminium frames, and common reasons people get in touch are a bead that doesn’t match the frame and black, perished sealant on frames.

Homes in small places like Long Green often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.

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

Common questions in Long Green

Can you help a landlord with a rental near Braintree Freeport station?

Yes, rental work is part of what we do. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we will send you a clear quote.

Will you come out to Long Green?

Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Will there be a smell?

It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.

Can you do the inside joint as well?

Yes. Inside, the joint between frame and plaster is sealed neatly, using a paintable sealant if you want to decorate.

What information do you need?

The location, the problem and the rough size of the job. Photos by email help too.

How long does it take to reseal the windows on a house?

It depends on access, the old mastic and the size of the frames. You’ll know the timing when we quote.

Can resealing stop a draught around my window?

Yes, if the air is getting in around the frame. If it’s through the window’s own seals or a hinge, that is a different fix, and we will say so.

Are you insured?

Yes. Full insurance covers our work, and we can confirm the details when we quote.

How the visit works

At the end, we look at the finished work together and explain the cure time. The work normally takes a morning for a couple of windows and a door, depending on the amount of work. For a village or hamlet like Long Green, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. Each frame is looked over and we agree which ones need resealing.
  2. We remove the old mastic and clean the frame edge and wall.
  3. Deep gaps get closed-cell backing rod to set the depth.
  4. The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
  5. We tool each bead neatly and check every joint is closed.

Getting ready for the visit

  • Plan for the work area to be out of bounds to pets and children
  • Mention any tricky access
  • Let us know if you’ve seen damp or leaks

What we are called out for in Long Green

Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. If the sealant cannot stretch, it splits.

Most people get in touch when they notice one of these:

  • Gaps left after new windows were fitted
  • Draughty joints inside around the window
  • Old mastic that has gone black or come away
  • Cold air getting in at the frame edge

If you live in an older home near St Barnabas, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What your quote should include

  • Whether they’re fully insured
  • How long to leave it before use
  • Whether the sealant suits the joint
  • How hidden problems are handled

How to choose a mastic man

Why deal with it now?

If you’re painting or rendering, reseal at the same time. Fresh joints finish the job neatly. Around Long Green, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

There are no prices on our website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.

Why book with us

  • One-year guarantee on every job
  • Fully insured
  • Arbo and Everbuild products
  • Any old sealant cut out fully, not covered over

Read our cost guide and what customers say.

DIY sealant or a professional job?

If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Keeping the joints in good condition

Simple care keeps the joints in good condition. We recommend:

  • Keep solvents and bleach off the sealant
  • Look round the frames every year or so
  • Make sure the drainage slots aren’t blocked
  • Repaint timber before it’s bare

Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak, and if anything looks wrong, just ring 0345 464 0079 or drop us an email.

Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.

Quotes for window mastic in Long Green

We don’t publish a price list, because no two jobs are the same. What we look at:

  • Which sealant suits the joint
  • Whether there’s mould to deal with
  • How many areas need sealing
  • How easy the joints are to reach

Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

What to tell us for a quote

To help us quote quickly, let us know:

  • Where the job is, and your postcode
  • Any access issues, like height or stairs
  • Roughly how big the job is
  • The type of property

For a quick quote, get us on the phone, or email us if that is easier. Tell us about the joints that need doing and we’ll talk you through the work before giving you a price.

What we cannot put right

New sealant cannot fix everything, and we’ll tell you before we start. It will not solve:

  • Penetrating damp from a failed cavity tray or render
  • Soft or decayed wood in the frame
  • Condensation trapped between the panes

If in doubt, phone 0345 464 0079 or email us and we’ll say what we think.
