Denise from West Allis

I recently replaced my windows in my patio room. I received multiple quotes from other companies, but decided to move forward with Allis and I’m so glad I did! From start to finish my experience was wonderful. Excellent customer service from the office staff, and the sales representative that was out wasn’t pushy and didn’t have a high pressure sales pitch. The installers arrived on time, they were thorough, friendly, and did a fantastic job. They did a great job of cleaning up after themselves as well. A big reason I chose Allis Windows Doors and More was because they don’t use subcontractors and have their own installation team backed by a promising workmanship warranty. Moving forward Allis Windows Doors and More will be the only company I contact for all of my home improvement needs!

I am a highly satisfied customer of Allis Windows.  Starting with Ben the sales person, to the lead foreman, the workers and the project manager Mike. The work was excellent!  I have absolutely no complaints and in today’s market it is really hard to find window installers who take pride in their work and have respect for their customer’s needs. I did a lot of research before making the decision to go with Allis Windows. The quality of their work was commented on by my neighbors, one of them who is in building construction. The pricing was competitive, and their integrity superb.  I would highly recommend this business if you are looking for a window specialist.

We would like to take this opportunity to express our delight with our products and service from Allis Windows, Doors and More. We really appreciated the expertise that Allis offered in helping us choose the best products for our needs and budget. Their installers were professional, prompt, neat and friendly. We couldn’t have asked for a better overall experience. If you are looking for a professional company to help you with your needs, this is the place to go.

Betty from Greenfield

I’m so happy with my three patio doors and window that opens! Colin and Jim were the best! Friendly, quick and the neatest contractor workers I’ve ever experienced. All in all this was a great experience for me and I’m already bragging about your company to my fellow condo residents.

Deb from Cudahy

Mike and Allen did a great job on my window, second floor bedroom window and back doors. These 2 guys worked their butts off. They were here all day, they were professional, they put down walk way blankets, which they didn’t need to do. They showed and explained everything to me. They asked me my opinion on a few matters too. The job was hard but wow what a difference. I just wanted them to know I am very pleased with the results and the hard work they did. This is the second time I have used Allis. When I will be doing the front doors, guess who I am going to call? Allis that’s who. A big thank you again.
