Re: Project Timing: Siding, Windows, Gutters, Extension
IF the windows are of descent quality (most 100 year old windows are) then you might consider saving a LOT of money and installing good quality storm windows instead. Some studies show the payback period form actual energy savings is longer than the life of the windows. 100 year old windows are made to be rebuilt and can last another hundred years. Most studies show that vinyl replacements are typically replaced again within 20-30 years.... and it will take 30-150 years to recover the energy savings.
We replaced windows on a 1968 home and the savings were minimal. Maybe $20/month for a $5000 project.
Keep in mind that after all of these upgrades, your heating and cooling will be oversized, which can make it much less efficient.
Just something to think about.
On my home, I have a LOT of windows. IT would cost about $25k to replace them. Even if I cut my energy bills in half (not going to happen) it would still be a 20+ year payback.
