We found the company on line. The response was fast. Eddy came and made the recommendation. The explanation was clear. The two of them did the work as planned. Professional and reasonable.

We replaced 15 windows, front door and patio door, and over I had a great experience coming here for the first time! Eddy from Peaceful was so helpful and provided me thoughtful insight on my questions with the product. After a few meetings with different companies, I found that Peaceful has good products, great pricing and as well great service. Would totally recommend.

Outstanding quality and service! Although I expected mess, installers came to my house and literally isolated and segmented each room to mitigate any dust penetrating inside the house as it was highly important to me. Prices were more than fair along with the professional advise. Sales person cut to the point giving prices which were more than fair. Actually I've got over 20% of savings just comparing Peaceful offer with the competitors I had at my house. The whole windows and door replacement took literally few hours with no mess and fair prices - that was a great value and extremely friendly attitude Highly recommended!!!

The owner, Eddy, was very respectful and understood our needs. The consultation was very informative and didn't push us to make a decision like some other companies. He helped us choose the best design to fit our home and the prices were very reasonable. We chose Peaceful over a few other companies because of the way he treated us. The finished product looks amazing and our house finally has the curb appeal that we have always wanted. Thank you Eddy from Peaceful!
