Window mastic in Wigginton

Window mastic in Wigginton, done properly

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. If you have cracked or shrunken mastic around the frame and damp patches on the reveal after heavy rain, we can put it right.

Somewhere as small as Wigginton, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.

You are covered for a year from the day we finish. If anything isn’t right with it, phone 0345 464 0079 or email us.

Looking after it afterwards

A little care helps the new joints last. We recommend:

  • Repaint timber before it’s bare
  • Avoid harsh chemicals near the mastic
  • Keep paint off silicone joints
  • Air rooms to keep condensation down around windows

Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.

A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. A new joint closes it up.

How we quote for window mastic

Jobs vary more than people expect. What affects the quote:

  • Working hours on commercial sites
  • The type of sealant required
  • Whether the work is at height
  • Any mould that needs treating

A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

Asking for a quote

A few details help us give you an accurate quote. When you ask for a quote, tell us:

  • If someone has resealed it before
  • What the problem is, such as mould, gaps, leaks or cracking
  • Pictures of the joints, sent by email
  • Where the property is

Call for a quick quote, or email us if that’s easier. Describe what needs sealing and we’ll talk you through the work and send you a clear quote.

When something else is needed

Some problems need a builder, plumber or other trade rather than us:

  • Faulty window hardware
  • A failed sealed unit that has misted up
  • Soft or decayed wood in the frame

If you’re not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer before you book.

Where we work in Wigginton

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

Surface by surface

Aluminium frames

Coated aluminium needs a compatible sealant, and acetoxy silicones aren’t used, as they can attack some metals. Neutral-cure sealant is the safe choice.

Patio & French doors

Door frames take knocks and movement every time the doors are used. A flexible sealant copes with that.

How it works

Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a morning for a couple of windows and a door. For a village or hamlet like Wigginton, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. We check how each frame can be reached safely.
  2. Old, cracked mastic is removed completely, along with any loose debris.
  3. Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
  4. Deep voids are backed, then the sealant is gunned in.
  5. The joint is shaped to shed water and the area tidied.

Preparing for the visit

  • Keep pets and children clear of the area while we work
  • Tell us about access, such as stairs, a lift or high-level joints
  • Clear the area around the work

Window mastic in Wigginton: local notes

London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Cholesbury Manor House (about 2 miles south) nearby, there’s older building stock in the area around Wigginton as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.

Letting a property close to Tring station? Then renewing tired window mastic between tenants heads off draught and damp complaints. Homes close to Church of St Bartholomew (church of England) include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Managing a site like Bishop Wood Church of England Junior School? Then its window and door frames need their mastic kept sound, just like a home’s.

Why act early in Wigginton

Failed mastic isn’t a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that is needed. Problems with the glass or gaskets are for a window company, and we’ll say so. Older cottages and farmhouses around Wigginton can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Combining jobs into one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.

Should I try it myself first?

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.

Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

Wigginton: your questions answered

Do you cover Wigginton for window mastic?

Yes, Wigginton is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or email us and tell us what needs doing.

Will you come out to Wigginton?

Yes, Wigginton is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Do I have to be there?

Access is agreed with you when the job is booked. Indoors, that generally means someone at home.

Is it worth trying it myself?

It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.

Are you fully insured?

Yes. Full insurance covers our work, and we can confirm the details when we quote.

Do you seal inside as well as outside?

Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We can do either or both.

Will new mastic stop draughts?

It will if the frame joint is the problem. We check where the draught is before we start.

Can I paint over the new sealant?

That depends on the product. Some hybrid sealants can be painted; silicone can’t. Tell us if you are decorating and we will choose accordingly.
