I filed a police report for items that were stolen from my home when windows were installed by Allied Windows and Siding and I called to let them know. Bottom line, the ‘alleged’ thief mysteriously quit the company, suddenly disappeared and no one could find him. Odd I’d say.
The owner of the company offered to give me $ 400 dollars (out of his pocket since it wasn’t enough to file on their insurance) to settle my claim but my claim was more like $ 1200 to $ 1500 (2 men’s rings — one gold w/diamonds & onyx, the other one silver & a pneumatic nail gun). I cannot sell my soul for $ 400. Right is right and Allied Windows knows they were dead wrong on this one.

Allied Windows and Siding. If you want reliability and good pricing you should start looking at another company.
They are about 20% higher for the same widows and they make promises they cannot keep. I should have shopped around but I trusted them because Nolan Ryan did. What a joke!
They said the windows would be installed in 6 – 8 weeks. It took them 12 weeks to get the windows in and then they didn’t even have all of the parts to properly install the windows! Then they banged up my newly painted walls during install and made no resolution to fix them.
Update to posting. Since the first review and after paying off the windows in full the owner of the company is now trying to charge me more money. EVEN THOUGH I HAVE A ‘PAID IN FULL’ letter. Wow! Be careful of these guys. Not sure what type of tricks they are up to.

Had James Griffin come out to my house to give me a quote on replacing my 34 windows. He was very knowledgeable of the products and procedures of installing the windows and was able to answer all of my questions. Allied has a good product at a fair price.

After a god-awful 3 months dealing with Wonderful Windows, I was back to shopping windows and called Allied. I’d actually spoken to them months before and the sales guy, Greg, remembered me. He came over and gave me a quote and was very friendly. I asked for some references of similar type jobs and there was one just a few blocks away that I walked to and checked out. The owner wasn’t pleased that his information was shared without his permission, but otherwise he had good things to say about Allied.
I wanted some assurances so he had the installer/manager guy Rick came over. Rick really sold me on the company. He knew what he was talking about and he explained how they were going to install the windows (something that Wonderful did not do.) It was a particularly difficult job which I was upfront with, but Rick had experience with it. Rick kept in touch with me and responded when he said he would. He let me know when the windows arrived and then we scheduled the work. I ended up getting them installed 3 weeks early (and on my birthday weekend too! Yay!) because they had an opening.
Because of the complexity of the job it took 2 days, so the crew were out on a Sunday which they didn’t complain about. They cleaned up after themselves, were very polite, and put up with my questions and additional requests. Really great job.
The finished product is amazing. I live on a busy street and the new windows have seriously reduced the noise levels. I’m sure they’ll help with the A/C bills in the summer but my main reason to upgrade was noise and they really deliver.
My father recommended Allied to me initially (I really, really should have gone with them) and I’m definitely going to recommend them to my neighbors and friends. I’ll recommend Wonderful Windows to people I dislike.

These guys come in get right to work and do a great job on both siding and windows. Little on the messy side but very conscientious. Overall a great experience. Great Price.

Quality work at a fair price. Windows are a big improvement and siding was definitely needed. Crew of 4 or 5 worked through the weekend to complete the job and left the work area clean. After we discovered a problem, the crew foreman came back out on a Sunday to make sure the problem was fixed and everything was back together as new. They stand behind their work.
