Pass on the knowledge

Hi guys,

Just started my first round today. Got alot going on now here in the UK. Busy, busy by the looks of it.

Today I got asked a question by a New customer I signed up on my own. They asked about the white marks on the inside of the glass. Not on the inside of there house or the outside but actually inside the glass itself. Perhaps water spots? I’v no idea so I told the customer I don’t know but what I’ll do is I’ll find out and make sure I get back to her.

She has double glazing and there is a white mark. Any ideas?

Thanks

She needs a new window the seals are bad

Ah that’s unfortunate. Can the glass be removed from the white upvc?or does the whole window need replaced.

How did the seals end up bad?

The entire window wouldn’t need to be replaced, but the part that houses the effected glass does - make sense? For simplicity, windows essentially have three(?) parts - the frame, the top sash, and the bottom sash. If the type and style of window is still manufactured than a window repair or manufacturer can replace the effected portion.

In my area there’s a company that replaces the glass, puts in new gas, and reseals and it costs a lot less than replacing the whole window. You just bring them the sash. Perhaps someone offers something like that near you.

Customers always really appreciate when i give them that tip. In fact, I’m thinking of telling the company that i refer them constantly. Perhaps they’ll return the favor.

I see this frequently on residential as well. One customer had a renter break the interior pane out and clean the exterior one from the inside. She didn’t notice but I did.

The windowseal has failed and is letting moisture in between the panes. A double pane window is often called a " sealed unit " in the glazing industry. The window consists of 2 panes of glass with an aluminum spacer bar sandwiched in between to create an airspace which gives the window its " thermal resistance ". There is a sealer applied around the perimeter to bond the glass and aluminum spacer bar together ( hence the term " sealed unit "). Not sure about the U.S., but in Canada if you look closely on the spacer bar the year the window was manufactured is often stamped into the spacer bar. Over time the sealant dries out and is compromised letting moisture in between the panes. It first shows up as condensation… then over time it turns cloudy and etches into the glass. I’ve installed hundreds of sealed units… mostly because of seal failure, not because the window is broken. You can get about 10 yrs out of a window, depending on exposure to wind, rain, and proximity to the ocean, and the manufacturer usually warranties the window seal for 5yrs. I don’t charge people to clean those windows because of that and explain to the customer that JUST the glass needs replacing, not the whole frame. Hope this helps.
