We adapt each service to the specific needs of the property, from historic houses that require delicate care to modern buildings that require precise sealing or caulking.

Services we offer
Window Repair
Cracked glass? Difficulty opening or closing windows? Fog between the panes? Window repair services solve all common and complex problems in Elgin’s houses. We check hardware, seals, locks, and frames to eliminate functional problems without complete replacement, saving you money and maintaining the comfort and attractive appearance of your home.
Window restoration
Ideal for older homes or damaged but restorable frames, window restoration is a cost-effective and environmentally friendly alternative to replacement. We sand, reseal, repaint, and reglaze existing frames to restore them to their original appearance while improving their thermal performance. The result is windows that comply with local building codes and aesthetic requirements.
Window Sealing
Poor insulation often starts with worn or missing seals. Our window sealing service helps eliminate drafts, moisture intrusion, and rising energy bills. We use professional grade, weather resistant sealants that can withstand Elgin’s seasonal temperature variations
Glass replacement
Broken or fogged glass not only looks unsightly, but also reduces thermal insulation. Glass replacement is ideal for transitioning from single-pane to energy-efficient double- or triple-pane glass. We manufacture new glass to custom sizes and install it in existing frames, ensuring a secure fit and restoring full transparency and thermal insulation.
If you need window repairs or complete window replacement, our team is here to help. Contact us today for a detailed assessment and free offer.

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.

I hired Window Quality Works to handle window replacements and rot repair on two of my Chicagoland properties. They did a thorough and efficient job, working quickly without sacrificing quality. I was very satisfied with their work and will highly recommend them to other property owners. I look forward to working with them again in the future.
