Window mastic for Dibden homes and businesses

How it works

At the end, we look at the finished work together. The visit itself normally takes a morning for a couple of windows and a door, depending on the size of the job. A visit to Dibden is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. First, we go round the frames with you and agree the list.
  2. The old mastic is cut out and scraped back to clean surfaces.
  3. Where the gap is deep, backing rod goes in first.
  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.

Getting ready for the visit

  • Clear the area around the work
  • Tell us if parking is tricky
  • Keep children and pets away from the work area

Mr Mastic applicator sealing the top of a white uPVC door frame on a red-brick house

Different surfaces, different methods

uPVC windows

We clean the frame edge carefully so the plastic isn’t marked, then the sealant goes in between frame and wall and tooled smooth.

Aluminium frames

Coated aluminium needs a compatible sealant. Neutral-cure sealant is the safe choice.

When something else is needed

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

  • Misting between the panes of a double-glazed unit (that needs a new unit)
  • A sash or casement that will not close properly
  • A door that needs adjusting, rehanging or new seals

Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly.

What we seal

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

Your questions about window mastic in Dibden

Is Dibden within the area you cover?

Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Do you work for landlords with property near Southampton Town Quay station?

Yes. We work for landlords and letting agents as well as householders, and several properties can be quoted together. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.

How long before the joint can be used?

It depends on the product. We tell you how long to leave it before we go.

Do you do commercial work?

Yes. We can plan bigger jobs in stages.

Does someone need to be in?

It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.

Where is Mr Mastic based?

We work from Crawley. Our applicators cover Dibden, along with the rest of our area.

What should I tell you?

The location, the problem and the rough size of the job. If you can, email a few photos.

What do you put in the joint?

It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.

Leave it or put it right?

Working on frames from a ladder with a sealant gun isn’t easy, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. In an older home around Dibden, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.

Combining jobs into one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.

Why us?

  • Arbo and Everbuild products
  • One-year guarantee on every job
  • You choose the colour before work begins
  • An ARBOMaster approved applicator

How we quote for window mastic

Call for a quick quote. What matters most is:

  • The type of sealant required
  • Whether old sealant or filler has to be cut out
  • The amount of work
  • The number of rooms or windows

Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, call 0345 464 0079 or send us an email for an honest opinion and a quote.

What to tell us for a quote

When you contact us, it’s useful to know:

  • What’s wrong with the joints now
  • A few pictures by email, if you can
  • If someone has resealed it before
  • The rough size of the job

If you are in Dibden and need window mastic, phone 0345 464 0079 or send us an email. Tell us what the problem is and where, and you’ll get a clear quote before work begins.

How to look after the new joints

Once the sealant has cured, a few habits help it last:

  • Air rooms to keep condensation down around windows
  • Keep paint off silicone joints
  • Check the mastic once a year
  • Make sure the drainage slots aren’t blocked

On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.

Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.

Windows and doors in Dibden

Dibden is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

If you look after a building such as Applemore College, the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Southampton Town Quay station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. For an older house near a landmark such as Church of All Saints, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
