Glazing silicone for homes and businesses in Hexton

Sealant on glazing doesn’t last for ever. Weather and movement take their toll and cracked joints let water in. Renewing it keeps glazing joints doing their job. Common call-outs are for black or yellowed silicone on glass joints and leaks from the base of a shower screen, on glass-to-glass joints, glass balustrade bases and rooflights.

Somewhere as small as Hexton, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.

We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Windows and doors in Hexton

Historic houses like Harlington Manor (about 4.3 miles west) are a reminder that the area around Hexton 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 is traditional sand mastic. 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.

Managing a site like Hexton Junior Mixed and Infant School? Then its window and door frames need their mastic kept sound, just like a home’s. For landlords with property near Harlington station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.

Hexton is in Hertfordshire. From the centre of Hexton to the outskirts, glazing silicone is available for homes and businesses alike, from flats and houses to offices and hotels. Our area takes in 381 places across Hertfordshire, from the larger towns to small villages. London is on our list too, around 34 miles away.

Aftercare tips

Joint life depends on how it’s used and looked after. Here’s what we suggest:

  • Keep harsh solvents off the silicone
  • Use a gentle glass cleaner and a soft cloth
  • Run a squeegee over the glass when you are done
  • Inspect the sealant on glazing annually

Gentle products are best near the sealant. Strong solvents can soften or mark it.

Cracked glazing silicone means the joint has failed. Renewing it early keeps it simple compared with fixing water damage later.

What we are called out for in Hexton

Heat and cold make glass and frames move at different rates. Over years, that movement tears the silicone.

Most people get in touch after spotting one of these:

  • Leaking glazing joints on a rooflight
  • New silicone smeared over old sealant
  • Stained, discoloured glazing silicone
  • Conservatory leaks at frame and glazing joints

Homes close to Church of St Faith (Church of England) include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

  • Whether the sealant suits the joint
  • How hidden problems are handled

10 questions to ask before booking

DIY versus a professional finish

If you’ve already had a go yourself, that’s fine. We cut it out and start again.

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Different surfaces, different methods

Conservatory frames

Frame joints face sun and rain all year. Renewed sealant keeps water out.

Rooflights

A rooflight faces rain and sun from above. Its sealant ages faster than vertical joints.

For landlords and businesses

Landlords and letting agents in Hexton can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.

What affects the quote in Hexton

Call for a quick quote. The main things that affect it are:

  • Whether the work is at height
  • Mould in or behind the old joints
  • When we can work, for business premises
  • Which sealant suits the joint

There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

Helping us quote

To help us quote quickly, please include:

  • What’s wrong with the joints now
  • How many joints, rooms or windows are involved
  • Pictures of the joints, sent by email
  • Any access issues, like height or stairs

Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we will talk you through the work.

How it works

Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from an hour or two to most of a day, depending on the size of the job. Somewhere like Hexton 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 trace the leak and confirm it’s a sealant joint.
  2. We remove the old sealant carefully.
  3. We clean the glass and frame so the new silicone bonds.
  4. We lay the new bead and tool it smooth.
  5. We check the finished joints and test with water where it’s safe.

Getting ready for the visit

  • Tell us if parking is tricky
  • Let us know about stairs, lifts or work at height
  • On commercial sites, let us know about site rules
