Services We Offer
Window Sash Repair
The moving portion of your window, the sash, can become misaligned or damaged from years of use. We expertly repair mechanisms, rebalance weights, and ensure a perfect fit so your windows operate with ease and provide a tight seal.
Window Frame Repair
A warped or cracked frame compromises your window’s entire structure. We reinforce, resurface, and rebuild damaged frames to restore their original strength and alignment, which is crucial for security and preventing energy loss.
Window Sill Repair
As the first line of defense against the elements, sills are prone to weather damage. We expertly repair or fabricate new sills that perfectly match your home’s aesthetics, providing a durable, water-tight finish that protects your interior walls.
Rotten Wood Window Repair
Our specialized rotten wood window repair process is a art form. We surgically remove decay and use either dutchman patches or industrial-grade epoxy consolidants to rebuild the wood to its original profile and strength, saving your classic windows from being discarded.

I am so impressed with the team that came to replace my window. Not only was the workmanship superb—leaving me with what looks like a brand-new window—but the two gentlemen were incredibly polite and respectful. They even took off their shoes without me asking, which shows a real respect for your client's home. A fantastic experience all around!

Window Quality Works has been our trusted partner for three separate projects over the years. Simply put, they do amazing work. They've restored a variety of our wooden windows to look and function like new, and now they stand strong against Chicago's tough weather. Beyond the impeccable quality, they are a pleasure to work with—excellent communicators, efficient, and they always leave the workspace spotless. You can't ask for more.

I had a serious issue with rotted wooden sashes and sills. The team replaced them with new ones, and then carefully sealed and painted everything to ensure long-lasting durability. The pricing was reasonable, the estimate was fast, and the service was highly effective. They truly did an amazing job and gave me complete peace of mind!

These guys were a lifesaver when we needed to get our windows fixed quickly before selling our house. They responded immediately, came out, and fixed everything in just one day. The price was more than reasonable for such prompt and quality service. Thanks again for your help!

I contacted them for an estimate on my historic wooden windows, and the results exceeded all expectations. They didn't just give me a quote; they conducted a meticulous assessment of each window and offered thoughtful solutions. The care they took in restoring the sashes and sills was evident. My windows now operate smoothly and look beautiful. It's refreshing to find a company that still takes such pride in their work.

My search for a reliable sash repair company ended with WindowQW. From the beginning, they were transparent, walking me through the entire process and clearly explaining what could be salvaged versus what needed replacement. True to their word, they stuck to the agreed timeline and budget. They replaced rotting sills, freed up stuck sashes, and even upgraded the old ropes and pulleys. I'm thoroughly impressed and highly recommend them!

They See What Others Miss. Trustworthy and Skilled.
We had a few Pella windows with bad rot. The team didn't just fix what we pointed out; they did a full inspection and identified a couple of other issues we had missed. This is the second time we've used them, and once again, they did a fantastic job. They are highly recommended for their honesty and expertise.
