Not resolved

My wife & I are in a nightmare. We bought and remodeled our dream home two years ago and installed all Marvin windows & doors.

They began leaking almost immediately. After fighting with the builder for a year about installation it was discovered the windows themselves are defective. Marvin had an independent testing company come in over six months ago and the testing company confirmed they are defective. Water continues to penetrate and damage our home but Marvin is only willing to send us new windows and not pay for the installation (est > $130K) and the interior damage to our home (est >$100K).

Has anyone had any luck with this company? Help!

installation is 99% of your problems if they are not shimmed properly there will be problems. If they are not installed to Marvin's specifications then talk to who installed them.


Marvin quality is going down. I have problem with sliding door, frame was assembled with errors.

I will never buy again Marvin door or windows. For 2 doors we pay 6K + labor and have to be reworked on side.

Marvin windows are the worst window I've ever delt with as a builder I refuse to install them there weatherstripping leaks like a sive

29 years ago, our builder installed very expensive E-glass Marvin windows in our large home. Over the past two years, 13 windows have lost their seals with resulting moisture intrusion.

The hooks in three windows that hold the windows in an up position failed, and the entire window had to be replaced. In all, we have spent about $10,000 on replacement so far, with another $10,000 to go. Apparently, the year after we purchased the windows, they were discontinued.

We are appalled. Will never use Marvin products again.


I have 5 year old marvins. Im here because they are terrible, wet, drafting etc.

Cold in mn. My old wood slider single panes were better


Has anyone had trouble with Marvin hurricane windows fogging up in southern climates? This happens almost daily only on the outside of the windows.

We have been told that it is just one of the things that you deal with in southern climates.

We do not keep our home below 70 degrees at night. Question could this be a problem of the windows having lost the inert gas between the panes?

Installation is KEY. I would love to know if the installs were AAMA certified and what flashings and caulks were used.

Installers cut corners .We install Marvin and Integrity and have not had ONE leak in 30 years. We also partner with the best stucco and siding installers that go hand in hand with a great window install.

Marvin is still the best product out there and Ultrex is the best fiberglass window available.

to Anonymous Laguna Niguel, California, United States #929527

I just installed 16 Marvin Integrity Ultrex fiberglass casement windows. The weather seals were poorly cut in manufacture, so water drips inside the casement.

Once inside the casement, it drips down into the bottom 45s, many of which of which are not sealed, so from there it wicks in and ruins the wood sill. I have these leak problems with about eight of the sixteen installs. Moreover, the exterior mull covers were very sloppily installed and many of the interior plastic trim pieces arrived severely deformed. And you say you have never seen a Marvin window leak after installing them for 30 years?

In my opinion, based on my experience, I cannot imagine a plausible chance that you are anything less than a bald faced liar. I expect Marvin to fix these problems. If they do, then great.

If they don't, then they will never hear the end of it from me.

If you believe this than why are you anonymous might as well not comment


We have been dealing with a Marvin Integrity nightmare for the past 9 months. We used these windows and french doors for the new home we built.

The doors have been replaced 5 times already. Every double hung has been replaced at least once but 11 of them have had their 4th replacement. All of the awning windows have nails showing that never hit the frame. Let me note that most of these replacements were not even acceptable to the distributor in our area that handles all Marvin issues in my area.

They have done their best but they don't make the product which is TERRIBLE in my opinion.

I will never ever use them again. I hope this helps others from the same fate.


I have the Marvin ultrex sliders since 1998 I installed them myself they are the best windows I ever installed no leaks and after 16 years they work and feel and look like I just installed them. That's the test of time there is no better test sorry to hear you have that problem

These folks are uninformed, most new homes settle causing the frame to rack, and have tons of moisture, from new construction. Its all in the installation.

We have looked between Marvin and Anderson they are similar its the installers.

Make sure what ever you buy you can replace the seal in the frame this is where the problem starts!

We have 2004 Marvin Integrity windows. There has been mold since day one.

They came to look and haven't done anything about it.

I am tired of cleaning mold off of the vinyl inner track. Any ideas how to proceed?


This site is very illuminating. We are shopping windows and sliding doors now for a new custom home.

We were set on Marvin.

Now we plan to expand our search. Too many dissatisfied customers.

to Doug Rose Chicago, Illinois, United States #597270

Same here in Chicago.... had been set on Marvin and will now look @ Andersen.

to Eric #628522

DO NOT BUY ANDERSENS. The glass is warranted for 20 yrs.

Vinyl clad comes off. Andersen says other parts warranted for 10 yrs. Vinly exterior clad came ungluged. Allowed water to go in between vinyl and wood.

Won't replace. Acts of God are not only hurricane, snow, ice....but sunshine an rain too. Thought they were the best. HYMBUG!!!Floor and frame rotting, termites trying to next up.

Terrible nightmare.

to ferg Chicago, Illinois, United States #649404

I find this hard to believe that the Andersen windows did this as they way the cladding is vacuum formed onto the sash and frame is highly unlikely the cladding could come off. Furthermore, it is not glued on.

I have been to their factory to see their process for myself. Are you sure you don't have another manufacturer's product?

to Eric #1022791

Don't buy Andersen they are just as bad, if not worst!!

to Doug Rose Midland, Texas, United States #666649

Illuminating? This is all conjecture.

There are not facts or details given here, what about the installation?...anyone can say anything.


I installed Marvin metal clad windows in 1997, new house and at the builders recommendation. These have leaked air from around the sash and built up huge ice on the surface every winter.

Marvin rep came out and blamed it all on humidity in the house, I have no more than 40 per cent in winter and there are only two of living here.

I see Marvin won a lawsuit againstPPG Industries in 2001 or 2002 claiming that the wood preservative PPG used failed.

Anyone had windows replaced because of this lawsuit?
