I have had my Alsco Windows for 6 years and they are great. We needed 2 adjusted and they took care of it. Support small businesses of Denver!

They don't follow through. Horrible company. Would never recommend them. Once the job was finished they completely ghosted us!

I really wish I read the reviews before trying to use this company. I needed a simple replacement part for a window. I started the process with Jean 5 months ago. After numerous emails, phone calls, we still don't have the parts, although she says that she has them in her office, and will ship them out to me. That was two months ago, and my last 3 emails have gone unanswered. I eventually got tired of her rude behavior and poor customer service and reached out to another dealer. I learned that I could order the parts directly. I also found out that there is specific sizing, and she never even asked me about the sizing...so what parts does she supposedly have in her office ready to ship to me? Very poor customer service. Jean is rude and inconsiderate, and just wasted months of my time.

ONLY ONE STAR BECAUSE IT'S THE MINIMUM REQUIRED TO POST...Custom slider installed (weeks late) - Door has had issues from day one - screen door became inoperable and had holes on delivery, slider door handle not secure, door frame is falling apart, hardware doesn’t latch properly, just a few issues with ONE door! Company ignores phone calls and warranty is a joke. The owner, Jean Gravina, even asked for a recommendation yet she refuses to even acknowledge our issues. It has been 8 years!

We have had a great experience with Alsco. I cannot describe enough without writing a 2 page review how much they helped us with our insurance claim. The insurance agency was only going to replace 4 windows due to damage but when Alsco came out and Matt helped us he caught so many items that we would have been taken for without having the understanding of how window replacement worked. Matt and Alsco were able to get us the increase of what we paid high premiums in insurance for our hail damage claim. I would strongly suggest you use them as the value in how they understand how to work with insurance companies and the programs they use is immensely important. Also the windows we get have a life time warranty. I cannot give enough recommendations to Jean, Matt and Alsco.

Great customer service and they were meticulous about the job they did. We will definitely refer to them. I have gone to big companies like Home Depot in the past and you have people without any knowledge. You can never get through and Home Depot employees didn't give a crap. This experience with Alsco was just so much easier!

DO NOT HIRE THIS COMPANY!! I paid them $24,000 to install new windows in my house. Shortly thereafter the window trim started to come apart. They came out twice but never fixed the problem. Called numerous times. They never returned my calls. Never came back. No explanation. I had to hire another company to correct their shoddy workmanship. I going to sue them in court. REPEAT DO NOT USE THIS COMPANY!

Do NOT use this company!! I worked there for three weeks Jan 2019. Still haven’t received a dime. Owner is nice but doesn’t know how to run a company. Lacks organization, leadership, money, customer service and the ability to make decisions. Always putting out fires and desperate for jobs to pay previous bills. Check BBB and stop in to visit location. One look at her desk will show you how your work will be. Disaster!!

Worst company ever!! Unorganized, sub contract all work out, can’t pay debt to suppliers, desperate for jobs and lacks communication. Drive past location or stop in to see for yourself. The yard is full of junk, trailer in back where two drunks live which I think is against code. Owners office has been hit by a tornado. If you need anymore proof check out BBB.

Dealing with this company in a siding project after the hail last May 2017 is the equal to buying a car and realizing you got a lemon. Project started in October 2017 and finally ended the end of October 2018. During this time period of one year, I had to point to what needed fixed, complained about their crews leaving cigarette buds all over my yard, on the gas meter, and leaving insulation loose in the backyard, not to mention all the crooked cuts, exposed areas, the gutters that they hung more than once, falling to the ground. Very frustrating! They received a lot of money for me to have to point multiple times over the year what needs to be done and continuously "fixed." I can go on and one about the headaches I have had to deal with, but enough said.

These guys were awesome. I called to get a new security door, energy efficient windows and a security light. They were kind, prompt and had competitive prices. I'd use them again in the future.

This is a great company I am glad I called them! I had a broken window in my house and my landlord took forever to do anything. I reached out these guys and they fixed our window in an reasonable amount of time. They were prompt and on time very courteous on the phone and in person. The price was very reasonable. I recommend everyone give them a call and see what they can do for you like they did for me!
