Window mastic for homes and businesses in Walberton

Most frames have an outside joint and an inside one. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. Either or both can be done. If you have damp patches on the reveal after heavy rain and whistling draughts around closed windows, we can help, whatever the surface.

Outdoor sealant needs dry, clean surfaces, so work on frames around Walberton is planned for dry weather. Let us know about access to all the frames, upstairs ones included.

Every job is covered by our one-year guarantee.

Surface by surface

Timber windows & doors

Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We’ll tell you which suits your home.

Composite doors

Front doors take the weather head on, and the top and bottom corners tend to fail first. Those corners get the most care.

FAQs for Walberton

Do you cover Walberton for window mastic?

Yes. Our work covers London and the South East, and Walberton is part of that. Just phone 0345 464 0079 or email us with a few details of the job, and we will give you a clear quote.

Do you work for landlords with property near Barnham station?

Will resealing my frames help with draughts?

If the draught is coming in around the frame, yes. If it’s through the window’s own seals or a hinge, that’s a different fix, and we’ll say so.

What should I tell you?

Let us know what needs doing and where, plus pictures if you have them. If we need more, we’ll ask.

What sealant do you use?

The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.

Is the work guaranteed?

Yes. All our work carries a 12-month guarantee, and we are ARBOMaster approved applicators.

Where are you based?

Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.

Are you an approved applicator?

Yes. We hold ARBOMaster approved applicator status, and we’re fully insured.

Leave it or put it right?

Draughts and leaks don’t always mean new windows. Where the frames are sound, new mastic normally deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we will tell you. In a small place like Walberton, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

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

Why us?

  • A sealant colour to suit the surroundings
  • Every job guaranteed for a year
  • We agree the colour with you first
  • Any old sealant cut out fully, not covered over

The process

At the end, we look at the finished work together. The visit itself generally takes a few hours for a few frames, or a day or more for a whole house, depending on the size of the job. Somewhere like Walberton needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  1. First we look at every frame and agree the list.
  2. We remove the old mastic and clean the frame and the wall.
  3. Deep gaps are filled with backing rod to set the depth.
  4. We apply a weatherproof sealant to match the frame and tool it neatly.
  5. Finally we tidy up and check each joint.

Getting ready for the visit

  • Let us know if you’ve seen damp or leaks
  • Tell us if parking is tricky
  • Move anything stored near the joints

Do you need window mastic in Walberton?

Sills take more water than any other part of a window, and the ends of the sill, where it meets the wall, are where it gets in. When that sealant fails, water gets into the wall or under the frame.

Keep an eye out for any of the following:

  • Draughty joints inside around the window
  • White mastic on grey or black frames
  • Whistling draughts around closed windows
  • Cracked sealant at the sill ends

Letting a property close to Barnham station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

10 questions to ask before booking

Looking after it afterwards

To keep the joints looking good and working properly:

  • Look round the frames every year or so
  • Keep timber frames painted
  • Ventilate rooms so frames don’t stay wet inside
  • Don’t use solvent cleaners on the joint

Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak.

Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.

Quotes for window mastic in Walberton

There’s no set price list. The quote depends on:

  • The product the joint needs
  • How many rooms, windows or areas are involved
  • Working hours on commercial sites
  • Access and height

Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will explain what it covers.

Helping us quote

Photos help, but a description is a good start. Try to tell us:

  • Where the property is
  • The problem you’ve noticed
  • Whether it’s a home or a business
  • Photos by email, if that’s easy

Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is. Whenever you’re ready, phone 0345 464 0079 or email us.

When something else is needed

Before booking, it’s worth knowing the limits:

  • Condensation trapped between the panes
  • Draughts through the window seals rather than the frame
  • A frame that has rotted at the joint

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

Windows and doors in Walberton

London and the South East are among the drier parts of the UK, 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 Walberton and Binsted CofE Primary School, the mastic around its windows and doors needs looking after like any other building’s.
