Special thanks to Frank Kramarik, General Manager, for being patient and thoroughly answering all my questions during the interview, quote and contract signing process. The window installers, Moises Alas and Augusto Mazariesgos were prompt and installed my windows in a timely manner, without any issues. After installation, they explained and demonstrated how to efficiently use my new windows, as well as, made sure the work area was clear of all debris. They did an excellent job! Thank you once again for making my window replacements a stess-free experience. I highly recommend Window World. My windows are beautiful!
- CWC WardAug 13, 20265.0I had my windows re-installed to STC windows vs the double pane windows that were installed a few months ago. The workers and the manager at the Waldorf location complained the project in a timely manner.
- SASarah AugustoskiAug 3, 20264.0We recently had new windows installed by Window World, and the experience was outstanding from start to finish, thanks largely to Moises Alas! He was professional, knowledgeable, and took the time to walk us through every step of the process. His attention to detail and genuine care for getting the job done right really stood out. Moises made sure all our questions were answered. The final result looks fantastic, and our home already feels more energy-efficient. Highly recommend this team!
