Salesman indicated we could have in much quicker than reality.  Some days the crew pulled off for a "do over" somewhere else or did not show up at all. We were very happy with everything EXCEPT for three things:
1.   the beadboard trim (or maybe you could call it retainer piece) had anywhere from 0 to over /4" gap that looked bad. They told me several times that that piece was the smallest they made and that was the best they could do.
2.   One corner piece was cut short so it looked bad.  When we complained about the this, they just put a lot of calk in the corner to cover it up.  I've been told calk should never be used on the fake beadboard (nor trim) to give it room to expand and contract. 
3.  Above two windows, the construction is such that it looks like the window is leaning.  There is one thin strip that is almost 1/4" thicker on one side than the other.  If this had been a 1" thick (vertical) piece, it would not be so noticeable but it is a very narrow piece.  I complained about that and they said the room was not level and brought a laser level to prove it.  There is approx. 3/8" drop over the 18' of the room, but they have approx 1/4" drop over course of 3' window which is huge difference. We argued over this over several weeks and the guy in charge had told me three different times "if I had made the measurements, we would not have this problem" (he was recovering from surgery when the measurements were done). To me, that was admission that the error was theirs.  They steadfastly refused to fix the problem and finally offered a settlement of 5% discount of the unpaid balance.  I accepted since there seemed to be no other option. I considered the settlement for this item only.
Later when I went to their store, they had a demo room set up with beadboard and trim just like I have EXCEPT there was no ugly gap between the trim and the beadboard! The fit was very snug! It was obvious that they had a smaller trim piece than the one they installed for me.  I then wrote the local store and sent a copy to corporate headquarters, complaining about the poor choice of materials and workmanship and requesting they correct it under their warranty.  The local manager called me and in essence told me that I had settled for a lesser amount and that was it. They would do nothing else.  In other words, they "settle" on one thing and then claim it covers all workmanship and material.  The salesman made me think there was a lifetime warranty on labor and material for the whole room. But upon reading very carefully the "warranty" certificate, it only covers the vacuum in the windows and screens if not damaged by mechanical means.
To summarize, we love everything EXCEPT the unsightly mismatched trim pieces on the beadboard and the unsightly angle on the piece above two windows (one window each on opposite sides of the room).  I have only dealt with one other contractor in my 45 years of adult life who refused to make his workmanship something he would be proud of.

Very well: good workmanship in a timely manner. I am well satisfied.

The project went well.  The carpenters were very skilled .   The brick had to be removed by hand instead of a saw, then the windows had to be framed properly, glass applied, and inside and outside details replaced.  There is wainscoting on the inside and he did a beautiful job reworking it.

We've been very happy with it and wonder why we didn't do it sooner. They appeared promptly to do the work, kept the work area appropriately clean and safe. They ordered the wrong door but corrected it quickly.

Not enough good words nor time to provide full details but suffice it to say, I will always call Champion for an estimate on any work they provide.

I got a quote from Champion to replace my aluminum windows.  One of the options they presented was what the salesman called their "old window" which they only offered a 20 year warranty on instead of lifetime.  He said he had the windows in his house and they were fine; of course since they were their old model they were less expensive which was appealing to me.  When I began reviewing all the paperwork there was an addendum included that you had to sign if you bought the old windows.  It stated that you were acknowledging that this windows had been created for a test market.  This worried me since the salesman claimed the only difference was the additional coatings on the new windows.  I called the salesperson and asked why the form said the windows were created for a test market.  He said he didn't know why that form said that and again stated they were simply the old windows that Champion no longer produced.  I asked him to get an explanation of why the form said one thing and he said another.  I told him I wasn't comfortable signing something like that especially when he claimed he didn't know/understand why that form even existed.  That threw up red flags to me.  The salesperson never called me back.  Ever.   I crossed Champion off my list and went with another provider.  I will probably never trust Champion.

Got a salesman to give price.  They sent a man to measure.  Then scheduled installers.  Everything was on time, and they cleaned up well.  Good windows!

Well, we had interaction with them and we are actually going to order our windows from them. We decided to go with the Ranky instead but it was a very good experience with Champion. The last interaction with them has been about 2 weeks ago. That is when we let them know, we inform them that we had been made a decision to go with the Ranky. Basically, I brought them to my home to sign a contract. We had a quote and everything. And we want it windows, I do not know if there are so many country, the grills between the windows has a layered look and Champion put in do that inside the grill. We did tunnel windows and they could do it, windows that we have round between us and the grills must have to be rounded dimensional grills like everything else was fine. They could do everything. I would recommend them. I think it was $48000. They have a lot of windows. They are very recyclable. They manufacture and sell their windows and that was a big plus. And Doranti, the other company that you asked about, is actually a distributor for Sunrise van card which is the window that we are going to use. That is not fair to them, obviously, I rather had a lot less but base on the other quotes we got, I would say, they were very competitive.

The guy that came out was really knowledgeable and professional but the price he gave was way high. I would definitely not use them.

Installer was excellent, showed up when said they would, installation went very well.
However, two windows did not fit and were re-ordered. Quality of the finished product was very poor in relation to the price i paid. We went with the most expensive estimate believing the quality would be excellent. We learned a very important lesson. 
After windows that did not fit and reordered, it was found one of those windows was defective, all the windows had rough welded joints which had to be smoothed with a dramel tool.
I do not believe i would go with the same manufacturer of windows.After approximately a month after the deal was made the job is still not complete.

I took Angie's recommendation on Chmapion and was very, very glad I did. The windows were a little more than else where but the quality, service and professionalism of this compnay was outstanding...as advertised on Angie's List. Would definitely recommend Champion to anyone. They even attended meetings of the Historical Commission for me while I was out of town on business. They even made the case and filled out the application for this step as well.

Their product was identical (roofing) or comparable to at least one other contractor that I had considered, but was nearly double the price.  The sales rep who came to my home was not impressive at all.

After I had signed the contract (& paid a 1/3 deposit), I found out from neighbors that I prob over-paid for this job.  My next-door neighbor examined the job for me & found several areas where there should have been 2 nails at the seams, and there was only one.  This meant that I had to call them back out to fix this.  They came promptly, however, because I had not yet paid the remainder 2/3 of the price.  I was also not too happy that they

Perfectly. They have done work for me over the years I have lived in my home. They are professional and do excellent work. I would recommend them to anyone.

.They were responsive, probably more substantive than most. I feel the quality is worth the extra price.

There were some minor problems with the doors closing but they kept working with it until it was perfect.

They are a quality company. They do an extra measuring of the windows. We were very satisfied when they did the first half of the house.

The experience with Champion Window of Birmingham was very good, except there were a couple of things that they didn't do that I wanted done and the manager couldn't deal with me. I had seen something in the brochure and I wanted it and he said that it was an outdated brochure so he couldn't give it to me. I would use them again because the work done was very good and the people that they had sent out were great and professional.

I had always wanted a sunroom to enjoy looking at the backyard.  An architect told me to consult one of the sunroom companies rather than building onto my house.  I contacted Champion and a representative came to my house within two days and helped me pick out the type and size that was best. 
It took about four months to build due to bad weather, but now I have a heated/air conditioned glass room that is beautiful.
My second encounter with Champion was when I decided to add custom tall, narrow windows to my dark livingroom.  Champion sent the very best  carpenter and his assistants, and  now the windows let in so much light and are gorgeous assets. These windows cost about $4,000.00 but are worth every penny.  When you consider they had to cut through brick, much of it done by hand, that's a great price.

A very unpleasant experience.

Even though they did not perform the work, they saved me a lot of time in finding the right company to perform the service.

Only thing I would have changed, get the windows with the smaller panes (for decoration).  Adds a lot to the overall look of the house when all is said is done.  Cost more, but worth it.

We love them. We haven't had any complaints or problems.

They were very professional. All of the work they did was great. All of the employees that came out were super. No complaints whatsoever. This is actually the second job we had done by them. I tell everyone about them. Chris Baroody was the salesperson that came out and he's very easy to work with.
