Is parking a problem for a job in Sewardstonebury?

About our glazing silicone in Sewardstonebury

Glass replacement isn’t something we do, and misting between panes means a failed sealed unit. What we do is the silicone around the glass, which is where many leaks start. If you are dealing with drips on the inside of a conservatory window and new silicone smeared over old sealant, we can put it right, whatever the surface.

Much of London’s older housing was built with timber sash windows, some still in place and some long since replaced. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out, in Sewardstonebury as anywhere.

The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

What the job involves on each surface

Glass balustrade bases

Balustrade bases are exposed outdoors. Renewing the sealant keeps water out of the channel.

Conservatory frames

The joints where the conservatory meets the house take a lot of movement. We reseal them with a sealant suited to the frame.

How to look after the new joints

Good habits help new joints last longer. A few tips:

  • Check the silicone on glass every year or so
  • Act on drips or damp patches early
  • Use gentle products around the joints
  • Ventilate the conservatory to cut condensation

Keep conservatory gutters clear, so water drains away from the joints. Overflowing gutters can cause leaks of their own.

Shower screen leaks can go unnoticed. It can damage the floor or the ceiling below before you spot it.

Landlord and commercial work in Sewardstonebury

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

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.

Why act early in Sewardstonebury

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. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble for homes in Sewardstonebury.

What it costs depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before any work starts, so you know where you stand.

Why us?

  • Sealant colour chosen to suit
  • We’re fully insured
  • A choice of colours where the product allows
  • Over 20 years’ experience

When to call us in Sewardstonebury

Sealant laid over old sealant doesn’t last. Many failed joints we see have been topped up rather than cut out, and water gets between the layers.

Look out for these signs:

  • Failed sealant around rooflight glass
  • Water running down inside the glass
  • Failed joints on frameless glass
  • Silicone pulling away from the glass

If you look after a building such as Yardley Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Questions to ask before you book

  • How the colour is chosen
  • What happens if they find a problem under the old sealant
  • Who turns up on the day
  • Which sealant they’ll use, and why
