Thank you so much, Lang Exterior for the best experience!! We’re so glad we chose this company. This was a big decision for us, no doubt. These windows are truly amazing. From walking into the gorgeous showroom where we had the most professional help and service to the on-time and accurate measurements. From that, installment fit like a glove. The crew were prompt pros. The caulk lines wow…. super clean inside and out. Details matter and this was detailed. It’s like the house is air tight when you close them up. Soundproofing the upstairs was affordable and important to us along with the screens that you can’t even see. We trust this company for their years of operation alone and the service they provided us.

Unbelievable difference in our home! We went from a home that was built in 1970 with original windows straight into the future with these windows. The affordable upgrades make a huge difference. From soundproofing the bedrooms (crazy quiet) to the window screens that you can’t even see are there on every window. We went from drafty old windows to an air-tight home. Install was clean, prompt and professional. Real Pros. Great crew all around. We’ve already had friends and neighbors asking because the difference it makes in your home leaves you shaking your head like what took us so long. Thank you Lang Exteriors. How can you not go with a company that has been open since the 50’s. I can’t stop staring at them. Enamored you will be.

By far the best windows and service in the Chicagoland area. Outside of the obvious savings, their repair services are incredibly convenient. I've built three homes and Lang windows never disappoint!
