Window mastic for Hornton homes and businesses

Window mastic for homes and businesses in Hornton

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, patio & French doors and window sills, and common reasons people get in touch are cracked or shrunken mastic around the frame and cracked internal joints between frame and plaster.

Somewhere as small as Hornton, 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.

Whatever the size of the job, it’s backed by our one-year guarantee.

Your questions about window mastic in Hornton

Can you do window mastic in Hornton?

Yes. Our work covers London and the South East, and Hornton is part of that. You can call 0345 464 0079 or email us and tell us what needs doing, and we’ll send you a clear quote.

What guarantee comes with window mastic in Hornton?

All our work, in Hornton and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.

Is there any odour?

There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.

Where do you work from?

We work from Crawley. Our applicators cover Hornton.

How long before the joint can be used?

Cure times vary by product and the conditions. We tell you how long to leave it before we go.

How long will my window job take?

Allow anything from an hour or two to a full day, depending on how many frames there are. Access and the amount of old mastic make the biggest difference.

Can I do it myself?

Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.

Can you do several jobs on one visit?

Yes. More than one area can go on one quote.

Why deal with it now?

Resealing frames is a short job: the visit takes a morning for a couple of windows and a door. Wait for damp to appear and there may be plaster and decorating to sort out too. Around Hornton, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or email us and we’ll talk you through it.

Frames and glazing around Hornton

With historic houses such as Upton House (about 1.6 miles west) nearby, there’s older building stock in the area around Hornton as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

If you live in an older home near Church of St John the Baptist, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For site and facilities teams at buildings such as Hornton Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Landlord and commercial work in Hornton

What happens on the day

Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a morning for a couple of windows and a door. In a small place like Hornton, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. Each frame is looked over and we agree which ones need resealing.
  2. The old mastic is cut out and scraped back to clean surfaces.
  3. Deep gaps get closed-cell backing rod to set the depth.
  4. A flexible exterior sealant is applied in a colour to suit the frame.
  5. We tool each bead neatly and check every joint is closed.

How to prepare

  • Plan for the work area to be out of bounds to pets and children
  • Mention if the joints have been sealed before
  • Let us know about stairs, lifts or work at height

Quotes for window mastic in Hornton

You will get a clear quote before any work starts. It takes into account:

  • Whether there’s mould to deal with
  • The size of the job
  • The type of sealant required
  • Access and height

Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Asking for a quote

There’s no need for technical detail. It helps if you can tell us:

  • Where the job is, and your postcode
  • What’s wrong with the joints now
  • If it’s domestic, commercial or a hotel
  • How we’d reach the joints

The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is.

What the job involves on each surface

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.

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

In fairness, some problems need a different trade:

  • A door that needs adjusting, rehanging or new seals
  • Damp problems in the wall away from the window
  • A frame that has rotted at the joint

Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly before you book.

Can I do it myself?

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
