Aftercare tips

After the cure time, these simple habits help:

  • Squeegee the shower screen after each use
  • Avoid scraping close to the bead
  • Clean glass with a mild cleaner and a soft cloth
  • Inspect the sealant on glazing annually

Keep the new joints dry for as long as we advise so the silicone can set properly. From then on, a mild glass cleaner is all it needs.

Act on black or lifting silicone early. Peeling silicone lets water in behind and the problem grows.

Glazing silicone in Headley

Glass and frames expand and contract differently, so the sealant between them does a lot of work. When it cracks or lets go, water gets in. We cut it out and reseal with a glazing silicone suited to the joint. We work on glass-to-glass joints, glass-to-frame joints and glass balustrade bases, and people most often call us about new silicone smeared over old sealant and split or lifting silicone on glass.

Around Headley, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.

Every job is covered by our 12-month guarantee, wherever you are in Hampshire.

Quotes for glazing silicone in Headley

You’ll get a clear quote before we start. It’s based on:

  • How much there is to do

  • How easy the joints are to reach
  • How much old sealant there is and how hard it is to remove

No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.

  • The rough size of the job
  • The address or postcode of the job

Frames and glazing around Headley

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 live in an older home near Church of All Saints, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For landlords with property near Liphook station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. Managing a site like The Holme Church of England Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.

The process

Most of a good job is in the preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours for most jobs. Somewhere like Headley needs a little journey planning: 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 look at the glazing and agree which joints need resealing.
  2. Old sealant is removed from the glass and frame.
  3. We clean and prepare the joint.
  4. New glazing silicone goes in and is finished neatly.
  5. We inspect the work and test it where we can.

How to prepare

  • Tell us about any water getting in
  • Mention any parking rules near the property
  • On commercial sites, let us know about site rules

Advice

Can I do it myself?

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Leave it or put it right?

Silicone around glazing needs the right product. General-purpose sealant from a DIY shop may not suit glass or the frame, so we use neutral-cure glazing silicone. Older cottages and farmhouses around Headley can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.

Why us?

  • Sealant colour chosen to suit
  • Neat joints and a tidy finish
  • Colour agreed with you before we start
  • We never seal over old sealant
