Aftercare tips

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

  • Wipe condensation off the frames
  • Keep solvents and bleach off the sealant
  • Avoid blasting the frames with a pressure washer
  • Do not paint over the silicone

Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.

Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and a cold room gets colder. A new joint closes it up.

How we handle window mastic in Nutbourne

Some gaps around frames are far deeper than they look. Filling it with sealant alone leaves a joint that cannot move properly, so deep gaps get backing rod first. That way the new bead bonds to the frame and the wall only. We work on uPVC windows, composite doors and window sills, and the jobs we see most are water coming in at the bottom corners of a door and cracked or shrunken mastic around the frame.

Mastic can only go onto a dry, clean joint, so window work in Nutbourne is booked around the forecast. Let us know about access to all the frames, upstairs ones included.

Whatever the size of the job, you get the same one-year guarantee.

Different surfaces, different methods

Patio & French doors

Door frames take knocks and movement every time the doors are used. The sealant must cope with it without cracking.

Composite doors

Draughts round the door leaf usually come from worn seals or adjustment, not the mastic. We seal the frame and let you know about anything else.

What affects the quote in Nutbourne

We quote each job individually. These are the things that affect it:

  • The old material and how stubborn it is
  • Whether the work is at height
  • Whether there’s mould to deal with
  • When we can work, for business premises

No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.

Asking for a quote

The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:

  • Any access issues, like height or stairs
  • Whether it has been sealed before
  • Photos by email, if that’s easy
  • How many joints, rooms or windows are involved

A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.

DIY versus a professional finish

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.

Work for landlords, hotels and businesses

We also work for property managers and facilities teams. We can quote a run of properties together, and we are fully insured.

Landlords and agents in Nutbourne can book us as well as householders. Resealing between tenancies is a simple way to keep a property in good order.

Questions from Nutbourne

Do you work for landlords with property near Pulborough station?

Yes, rental work is part of what we do. Just call 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.

Is Nutbourne in your area for window mastic?

Yes, Nutbourne is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or email us and let us know what needs doing, and we will give you a clear quote.

What does window mastic cost?

Size, access and the old material all affect the cost. Ask us for a quote.

Do you do commercial work?

Yes. We have worked for hotels, offices and other businesses.

Do I have to be there?

Access is agreed with you when the job is booked. For inside work, that normally means someone being in.

Is there any odour?

Possibly a little. Any smell clears as the sealant cures, and ventilation helps.

Does the work come with a guarantee?

Yes, with our 12-month guarantee. Keeping drainage clear and checking the joints yearly helps them last.

Will you leave a mess?

Not at all. We work neatly, protect the area around the joints and tidy up afterwards.

What we cannot put right

Honest advice matters more to us than a booking, so here’s what new sealant won’t do:

  • A frame that has rotted at the joint
  • Worn gaskets, brush seals or a door that has dropped
  • Damp coming through the wall itself rather than the frame joint

Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly.

What we seal

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

How the visit works

The work is kept neat and contained to the joints we are treating. Expect the work to take a morning for a couple of windows and a door. Somewhere like Nutbourne 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. We check each frame and agree which ones need doing.

Advice

Nutbourne homes and the weather

Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Old Place Manor (about 1.8 miles west) are a reminder that the area around Nutbourne has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.

For an older house near a landmark such as St Mary's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Letting a property close to Pulborough station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Managing a site like West Chiltington Community Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.
