Window mastic in Wickham Common

Honest limits

We’ll always be straight with you, so here’s what new sealant will not do:

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

If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think before you book.

Joints and surfaces we work on

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

Window mastic in Wickham Common, done properly

Behind a thin line of old mastic there’s sometimes a deep void. 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. Common call-outs are for damp patches on the reveal after heavy rain and cracked internal joints between frame and plaster, on patio & French doors, window sills and composite doors.

Homes in small places like Wickham Common often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.

A 12-month guarantee comes as standard.

Wickham Common homes and 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.

Rented homes near Fareham station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Managing a site like Wickham Church of England Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.

How it works

On the day, we look over the joints with you first, so you know exactly what we are doing. We protect the surfaces around the joints before any work begins. The work normally takes anything from an hour or two to a full day, depending on how many frames there are. Somewhere as small as Wickham Common, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. First we look at every frame and agree the list.
  2. The old mastic is cut out and the surfaces cleaned back.
  3. We fit backing rod in deep gaps so the sealant is the right depth.
  4. New exterior sealant goes on in a matching colour and is tooled smooth.
  5. Finally we tidy up and check each joint.

How to prepare

  • Mention if the joints have been sealed before
  • For indoor joints, keep the area dry beforehand if you can
  • For business premises, tell us about site rules or sign-in

Signs you need window mastic in Wickham Common

Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, and a gap filled solid can’t flex. That is what backing rod is for.

People usually contact us after spotting one of these:

  • Leaking joints at the ends of sills
  • Gaps left after new windows were fitted
  • Mastic that has split away from the wall
  • Cold air getting in at the frame edge

For an older house near a landmark such as Church of St Nicholas, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Questions to ask before you book

  • Who does the work, and how experienced they are
  • Which colour the sealant will be
  • The length of the guarantee
  • Are they insured?

10 questions to ask before you book

Can I do it myself?

Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

How the job changes by surface

Composite doors

Front doors take the weather head on. Those corners get the most care.

Patio & French doors

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

Why deal with it now?

Failed mastic is not a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. Problems with the glass or gaskets are for a window company, and we’ll say so. In a small place like Wickham Common, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, phone 0345 464 0079 or send us an email for an honest opinion and a quote.
