Part II of how I came about deciding to restore the wood windows in my house instead of simply tearing them out and installing new replacement windows. Part I at this link.
Of course, by this point I had decided replacement was not an option (except for the bathroom window, which I did replace with vinyl – I wouldn’t dream of building a shower with a wood window in the wall).
I learned about an organization in Columbus hosting a 2 day hands-on window restoration workshop, and I signed up right away. I even took my own tool belt so I wouldn’t look like such a novice. In reality, I did find I had a lot more knowledge than some of the others – a range of individuals who had never held a hammer, to a few woodworking professionals expanding their skills. Just a few hours in, and it felt like all the reading I had done about wood window restoration was coming to life in front of me. There is nothing better than learning by working alongside a seasoned professional craftsman.
I didn’t just learn the steps in the process, but I learned great tips from their years of experience; how to keep the sash cord from slipping into the wall cavity by accident; the right tool to carefully pry out the parting stop; how to remove brittle glazing without cracking the glass. And the right products such as glazing compound, sash chain v cord, and great online resources to order the correct replacement parts.
Beyond what I learned, the workshop took away my fear of doing a step wrong or getting in over my head.
I didn’t immediately drive home and tear every window apart – though I wanted to. But I did start ordering supplies and price checking half a dozen websites to find out which sold each product at the best price. Restoring windows on average is less expensive than replacing them, but that still doesn’t mean it is cheap – especially when the best price is ordering in bulk. So 1 gallon of this, 100 yards of that, 5 of these, 30 meters of this, and 300 copper nails. I was just about halfway through finishing the plaster repairs in the laundry room when I went to the workshop, and I made myself wait until I had the entire room painted & woodwork refinished. Then it was window time.
I intended Part III to be a step by step photograph process of removing, restoring, and reinstalling the double-wide laundry room windows. Unfortunately my computer decided to wreak havoc last weekend and my only resort was a complete hard drive reformatting & reinstalling the operating software. Thankfully I don’t keep files on my computer very long, I’ve learned to store most of my photographs & other important documents on my external hard drive. But for some reason, I had kept my house renovation photos saved on my pc and not yet moved to the external- it was easier and a few steps faster to edit photos & update blog posts. I lost the majority of my photos of house projects from this summer. Lesson learned the hard way. So Part III will switch to a different window in a different room of the house.
When I bought this humble bungalow (over a year ago!), one of the features I found most interesting was the distorted glass in each of the original wood windows. “Wavy” glass is an understatement. When I really study them, there are bubbles, circles, lines, and other imperfections in every piece of glass. I still remember the 1st or 2nd time looking at the house with the realtor, how beautiful the light danced on the walls through the imperfect glass. Of course, the deterioration of the windows and the rattling glass was one of the scariest features. While the whistling of the wind and drafts around each frame this past winter was an expensive feature.
Working in the field of downtown development, I’ve been lucky to attend dozens of workshops and training events about the importance of building preservation and wood windows. I’ve heard them use the fancy phrases, how wood windows are part of a building’s historic fabric, the vast difference between old growth wood and dimensional lumber available today. And more recently I’ve experienced how downtown revitalization grants can help with almost every aspect of restoring a historic building facade, but the Historic Preservation Office is adamant that grant funds will pay to have wood windows restored- not replaced.
So over the winter months — as I was reluctantly turning up the thermostat, putting more of my paycheck into the “heating” budget, and watching the shrink-wrap plastic flicker from the cold air blowing in around each window — I began seriously researching the best option for my house.
I do advise CAUTION here – only begin typing the word replacement, vinyl, fiberglass, aluminum clad, or easy-to-clean in any internet search engine and the only results will be replacement window companies – hundreds of them claiming that all of my home’s energy problems will be solved if I toss the old windows into a dumpster & install the cheapest vinyl windows on the market. Others claimed I could stand on the windows (before installing them I assume?), $99 window sales, solid vinyl sash frames, one finger open & close, multiple warranties, and even custom colors for the exterior to match any decor.
But then I searched for an answer to my real question, “wood windows restore or repair.” The results were countless forums, threads, magazines, blogs, and even energy efficient building research. They all said the same – wood windows, when restored correctly with the right materials, adding a mix of original and modern weather stripping, and with a quality storm window- will match or even outperform replacement windows in energy efficiency. Add to that the embodied energy already in the existing windows, the un-matchable strength of 100+ year old lumber, and the compiled data of historic home sales that show original windows add significantly to home & neighborhood values. Or do a little more online digging and read how 5 of the largest US replacement window manufacturers were recently charged with class action lawsuits against their false & deeply exaggerated “statistics” of energy savings they claim their windows will achieve. Eventually these 5 companies settled with the Federal Trade Commission to delete the language from their advertising when they can not consistently prove the numbers to be true.
Last summer I had 3 different window salesmen stop me while working outside or mowing the lawn. They tried their hardest to come inside, sit down and talk about their products, the “50% – 55% energy savings I could experience.” When one salesman revisited this spring, I asked him a simple question:
“These windows have lasted almost 100 years; Can you sell me a replacement window that will last that long?”
The answer is no. Many of the highest priced residential replacement windows offer only a 20 year (and very limited) manufacturers warranty. Even then the warranty is often for only the mechanical operations of the window – NOT on the low E gas seals, air-tightness, or their bold energy efficiency claims. And all the research I’ve read from professionals in the historic preservation world say property restored wood windows can last another 100 years (although with painting & glazing repairs in the middle at least once).
I read every online article, blog, and discussion thread I could find. I watched YouTube videos late into the evenings, trying to take notice of the slight differences from one professional’s process to the next – mostly minor, or they each have a different favorite method for steps such as removing paint, making repairs, etc. But the process is the same – remove all paint, remove all glazing, carefully remove glass. Sand, re-glue, prime, reglaze, paint, and re-install.
But I still had so many unknowns and fears about taking this on by myself: the details of weather-stripping (bronze? silicone bulb? vinyl flange? brush.., foam.., felt??) And what are the differences between the many types of glazing compound. Is that the same as glazing putty? And where do I find replacement sash cord that won’t stretch over time, or combination lift/sash locks? Oil or latex primer and then paint?
It was perfect timing to learn about a hands-on wood window workshop taking place in Columbus back in March, hosted by a new historic preservation group somewhat affiliated with the organization my workplace is involved with. Two days, hands on learning, BYOT (bring your own tools), and learn the entire process working alongside 3 professionals. Sign me up.
In Part 2 I’ll describe the workshop in depth, and the basic tools, methods, & products the professionals there taught us – based on each of their 30+ years in this work. But one blog I have found to be very helpful – and exactly step by step in line with the teachings from the workshop – is The Craftsman Blog. The writer is owner of a historic home restoration company so of course the entire blog is a very full resource for old home enthusiasts. But his specific posts detailing window restoration are almost a printable instruction guide. Thank you Scott for all the incredible content you share, I have learned so much from your blog!
I had purchased these wall sconces a while back at my favorite nearby architectural salvage shop in Ft. Wayne; sconces but no globes. Just down the street from the salvage business is the Habitat For Humanity ReStore, where the same day I found 2 glass globes that fit them perfect. Successful scavenging day!
They were pretty dirty, years of hairspray and dust I imagine. I was cautious to try any chemical cleaners on them, so instead I used 0000 steel wool, and lightly polished them to a mirror finish. The left is dirty, on the right is freshly polished.
And here it is hanging on the wall to the left of the medicine cabinet opening (no, I haven’t started building the medicine cabinet. I have started designing it though!). The sconces were just about 3/4 inch narrower than the 4″ round fixture boxes I installed in the walls, which meant I had to fill the space on either side. Although you can buy ready-made fixture box covers that would have worked for a round sconce, these are ellipse and the circular covers wouldn’t look right. So I made my own “medallions” by tracing the sconce onto a 1/4″ thick scrap board, and cut the outline with a handheld jigsaw 1/2″ outside of my pencil tracing. Some rigorous sanding to round over the top edges, and then 2 coats of bright white paint. Of course the wires and wire nuts had to pass through, so I cut a hole in the center of each one before painting. But it was still a trick with only 2 hands to wire the short wires together and tighten the sconce to the wall making sure the white medallion was centered all around.
But the real work this past month was going from this:
That’s not just woodwork stripped of paint, but 2 windows fully restored, ropes replaced, new lock-pulls, and weatherstripping installed. And if they look good, that’s nothing compared to how smoothly they operate and how tightly they close. I’m working on window 3 (of 10!) and documenting each step for a future post. It takes a little longer than tearing out and replacing, but the results are worth the extra effort!
