Glazing silicone in Kennington

How we handle glazing silicone in Kennington

We don’t replace glass and a misted double-glazed unit needs a glazier. What we do is the silicone around the glass, which is where many leaks start. If you have failed joints on frameless glass and silicone pulling away from the glass, we can help.

Around Kennington, conservatories, garden rooms and patio doors are often part of the house. Their glazing joints and frame seals are as much a part of the job as the windows, and any older timber or sash windows need a sealant that suits them.

Your job is guaranteed for a year, as with all our work.

FAQs for Kennington

Can you help a landlord with a rental near Radley station?

Yes. We work for landlords and agents as well as householders, and several properties can go on one quote. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.

Is Kennington in your area for glazing silicone?

Yes, Kennington is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear price.

What sealant do you use on glazing?

A glazing silicone chosen for the joint. Neutral-cure products suit most glass and frames, as some acetoxy types can attack certain metals.

Do you hold any approvals?

Yes. Mr Mastic is an ARBOMaster approved applicator.

Is it messy?

Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.

What guarantee do I get?

Every job comes with our one-year guarantee.

Do you remove the old sealant?

Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.

Do you do commercial work?

Yes. Hotels, offices and other businesses use us.

Why it’s worth doing now in Kennington

Glazing joints need a sealant made for the job. A general-purpose tube may not bond well or may react with the frame so we choose a glazing silicone instead. In a smaller place like Kennington, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.

Combining jobs into one visit is generally more efficient than separate visits. You’ll get one clear quote for the whole job.

Why us?

  • Old sealant always removed completely
  • We leave the area clean and tidy
  • ARBOMaster approved applicator
  • Colour agreed with you before we start

Looking after it afterwards

To keep the joints looking good and working properly:

  • Keep harsh solvents off the silicone
  • Check the gutters above the glazing for debris
  • Act on drips or damp patches early
  • Open vents or windows to let moisture out

Look over the glazing joints every year or so. Spotting a crack early means a simpler fix, before water gets in.

Don’t leave lifting or mouldy silicone on glazing. Once it starts to peel, water gets behind it and the problem grows.

Landlord and commercial work in Kennington

Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.

If you manage several properties in or around Kennington, several properties can go on one quote. Just tell us the addresses and what each one needs.

Should I try it myself first?

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

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.

When it isn’t the sealant

To be straight with you, some problems need a different trade:

  • Structural problems with a conservatory roof
  • Leaks from the roof covering or flashing (a roofer’s job)
  • A frame that needs repairing or replacing

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

What we seal

  • Rooflights
  • Glass-to-glass joints
  • Glass balustrade bases
  • Conservatory frames
  • Shower screens
  • Glass-to-frame joints

Surface by surface

Shower screens

Silicone holds the water in on frameless screens. We renew it without marking the glass.

Conservatory frames

The joints where the conservatory meets the house take a lot of movement. They’re resealed with a suitable sealant.

Windows and doors in Kennington

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. Historic houses like Holywell Manor (about 3.1 miles north) are a reminder that the area around Kennington has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.

Homes close to St Swithun's Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For landlords with property near Radley station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. Managing a site like St Swithun's CofE Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

What we do, step by step

When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes anything from an hour or two to most of a day, depending on the size of the job. For a job in Kennington, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. We look at the glazing and agree which joints need resealing.
  2. We cut away the failed silicone.
  3. We clean and prepare the joint.
  4. We apply and tool the new silicone.
  5. The joints are checked before we leave.

Preparing for the visit

  • Mention if the joints have been sealed before
  • Keep children and pets away from the work area
  • Let us know about stairs, lifts or work at height
