Rotting Window Frames
I hope that someone from the excellent group can help me with this
one. We've bought a 22 year-old house in the greater Toronto area. The window frames on the western side of the house are beginning to rot out. We had a home inspection done and the inspector suggested that the windows should be replaced next year or the year after at the very latest. I'm wondering if there isn't some way to save the windows, or at least delay the work. The windows are thermapane (sp?) and the seals are all still good. Could we not have the frames injected with a resin or something and then seal them. It seems such a waste to trash the whole set of windows because of this problem... not to mention the expense. Thanks for all replies. Peter H |

(Field-applied cladding, not the factory stuff where no wood is exposed to water.) Not a fan. Besides, if the rot is advanced enough, the window will still fail. -- aem sends... |

Yes, I saw something done on This Old House when they were doing some restoration. It was an epoxy material that dried hard and could be shaped and sanded to match. It is also important to find out the cause of the rot and eliminate the problem. Windows should last much longer with proper care and a coat of paint. http://www.thisoldhouse.com/toh/askt...058419,00.html Probably other materials available too. |

Bondo as used in auto body repair works quite well and is commonly available. Also you must find out if something happened to the wood that made it rot. It might just be a case of the west exposure and not painting/repainting the wood often enough as some people just don't realize that painting is a routine chore. |

Polyester plastic (which Bondo IS, DOES absorb water. So does Nylon and some of the Acetates. They will expand when wet, and severe freeze-thaw cylcles will cause it to disintegrate if wet. Epoxy, generally, does NOT absorb water. |

On 11/16/2009 6:58 PM Peter H spake thus:

Could we not have the frames injected with a resin or something and then seal them. It seems such a waste to trash the whole set of windows because of this problem... not to mention the expense. Having had recent experience doing just this, yes, it is possible to save windows this way. Depends, of course, on the extent of the rot. The window I rebuilt was a standard double-hung sash (single glazed), but there's no reason the same technique shouldn't work for your windows. The stuff you want to use is epoxy made for such purposes. I used something called PC-Woody, basically epoxy mixed with wood dust to about the consistency of peanut butter. I also embedded some steel hardware (all-thread rod and an angle bracket) to restore structural integrity to the corner that was completely rotted out. It takes a bit of doing: I ended up making a crude form to mold the stuff in. But it does work well. -- Who needs a junta or a dictatorship when you have a Congress blowing Wall Street, using the media as a condom? - harvested from Usenet |

Thanks for all replies. Peter H Why did they rot, the west side has enough sun to dry things out, is it the whole frame. First dig out whats loose and kill the rot with bleach. Minwax has a liqued hardener to be used on soft wood, you drill holes and inject the liqued. I think a syringe would be best. For holes ive used Bondo as that is the cheapest. A few other products mentioned might cost you 2-5x as much and do no more. Covering it all in aluminum will only hide the problem and cure nothing. But a question remains, what caused them to rot? |

What caused them to rot. That is a good question. I have a similar problem on south facing windows. It appears that the window company used a very susceptible piece of wood. The wood next to it and touching it is fine. The windows are aluminum clad at the factory. There is nothing on the outside to paint, however, aluminum venetian blinds on the inside can cause considerable condensation in winter. This soaks into seams and swells the wood which causes the paint to crack allowing more water to penetrate. The bad piece of wood over the years retains the water for months and has started to rot in spots after 25 years. I have soaked in epoxy penetrant and used epoxy putty to level the lower frame and it is still quite sturdy and useable. The window next to this one, made by the same manufacturer, facing east is fine. Sometimes a bad piece of wood is used when making the frame. It looks OK when new, but just does not hold up over time. |

Yes, there are epoxies for that purpose; as mentioned, Git Rot is one. The success in using them depends on the extent and type of rot; the epoxy needs to penetrate into the entire rotted area. If the rot is "wet" rot and superficial they would work IF the wood is completely dried first. If the rot is deep "dry" rot, you would need to drill numerous holes and fill them with epoxy...all the fungus causing the rot needs to be encapsulated. In either case, any missing wood can be replaced with Bondo after the epoxy sets. How practical it is to do that is impossible to say without knowning the extent of the rot. Quite possibly it would be cheaper to replace the windows considering the amount of work to fix them, prime and paint. Especially if the rot is also in the overhead member of the frame...try getting thin epoxy into *that* -- dadiOH ____________________________ dadiOH's dandies v3.06... ....a help file of info about MP3s, recording from LP/cassette and tips & tricks on this and that.

Get ordinary epoxy and after mixing it, thin with alcohol. You can add up to 10% alcohol without affecting the results. Lowes and Home depot sell brick molding and window sash. It's not that hard to cut out the bad parts and replace them on most windows. Unless the rot has gone way in. |

The home inspector could have answered your questions about repair rather than replacement. Rot signals damage by moisture, and long-term repair requires eliminating the source of this damage. Plastic and metal-covered windowframes are much easier to clean and maintain than (cheaper) wood. 2. You should be aware of the government-subsidized "Eco- Energy" programme for Ontario, see http://www.homeperformance.com/energ...ario-bc-canada This subsidizes ($150) an "energy audit" of your house (cost $300 to $450) and provides for part payment of upgrades that improve your energy economy. The federal government announced in 2008 (as an economic incentive) extra tax deductions for home improvements, but this has not yet been enacted for tax year 2009. -- Don Phillipson Carlsbad Springs (Ottawa, Canada) |
