From the consultation stage with Marko Windows & Doors, through the selection of windows and doors (we replaced 3 doors and numerous windows), scheduling, communication and the installation was all excellent. This company is very well organized, professional and the owner and the installers very knowledgeable. We had a ton of questions which they patiently answered and made various suggestions, so the consulting prior to confirming was very much appreciated and made us feel even more confident that we made the right choice selecting them to do this work. They were all kind, respectful of our home and completed a very high quality installation in a very efficient and clean manner. We are extremely pleased with the results and without any hesitation would recommend this company.
