Window Install

I am looking for opinions on the install of this window.

There were 6 others just like it. Looks wrong to me.

Any help would be most appreciated!


What type of window (manufacturer) is this?

Reference the Window Manufacturer’s recommendations for the installation to properly report the deficiencies that are present.

It almost has to be wrong!!!

I agree.

However, you need to Reference and Substantiate your Findings.

Common sense!!! Out the window.

Joe, I have no idea. I took one look at it and went “What the $%^&?”

I couldn’t see behind the aluminum siding to check if there was another flange or any flashing and couldn’t see how this setup would keep water outside the building envelope. So I wrote it up as “appears to be improperly installed”.

Have spent the last day online and in the local building centers looking for anything like these and have come up with zero.

How did this window look from the inside? I’ve seen this before, or something like it, and it occurred when the home-owner installed the window, squaring, levelling, and nailing, all from the inside, in order to be flush with his walls. It was in an older home, nothing was square, straight or level.

Ive installed alot of various types and styles of window in my day,and one look at that and there is no doubt that it is way wrong, with the flange outside of the siding I suspect the same thing as brian, installed to meet up with the inside wall with no regard to the important matters such as water intrusion

There was no trim. It was actually recessed in and drywalled.

Nice work on the inside, but wrong as I am learning.

You know the old saying, “If it looks wrong, it probably is!”


A good point to remember. We don’t have to fix it or expain how it should be. We just have to recognize that it is wrong. I would report:

"Windows improperly installed. No drip flashing and there appears to be no interior flashing or water seal. Gaps between window and siding leave room for water infiltration which can lead to wood rot and organic growth (mold).

Recommend evaluation and repair by a licensed and insured window contractor before the close of escrow."

You described the window, its condition and the possible risks if not fixed. You recommended what whould be done to fix the problem and the time frame that it shluld be done in, in order to protect your client. Can’t do more. No need to get to specific. If you do and you make one little misstatement, they can hang you for it.

Hope this helps.


Just looking for my own edification. I am always looking to learn something new. Hence, I ask questions! :smiley:

Edifying yourself in public?

How kinky. :mrgreen:

A drip cap would be good, and easy to install, that would avoid having to caulk every year.

Looks as if the window capping was installed with improper dimensions used . Barney Fife held the tape the wrong way The sad part even though it looks pretty from 5 feet away water,snow will go behind that capping and if it is caulked between the capping and the window all around , water will look for a place to go .be it behind the siding into the wall itself or in the house and rot everything away

This type of window installation was never part of the standard installation for any window. I have never seen anything like it.
Wood suggest and recommend highly that a Prominent Building Contractor approved by Anderson Window Corporation or Equal, make an Estimate for the proper repair.

This installation is drastically wrong and needs to be corrected at some cost to the owner.

That sucker didn’t look pretty from 30 feet away. It and its brothers were the first thing I noticed when I walked behind the house. Almost kept me from catching the crawlspace vents that were below grade because I was so busy staring at them! :smiley:

Hee Hee,
Good one.
The flange or fin should be nailed or screwed to the sheathing. Airbarrier over that, then flashing on top, then siding.
In this case, the window was installed AFTER the siding…and probably much later. But, hey, the price was right.

That flange should nail to the exterior sheathing (OSB or plywood) behind the siding. Siding should run down over the flange face and die into the top of the window frame. As installed it will direct water into the wall framing resulting in eventual fungal activity such as wood decay and possible damage to other wall materials.
You’ll go crazy trying to look up MFG’s installation instructions for every mis-installed window you see. “Appears incorrectly installed, recommend evaluation and correction by qualified contractor” would be my choice.

Just trying to increase my knowledge.

More knowledge means I can charge more money! :smiley:

The best way to report it if you can not find the Installation information or it is not available.

Go with your gut reaction.
