Big Mahalos to Victoria and Earl, true professionals and very polite. Knowledgeable of products, delivery, and installation. Even though one window wasn't delivered, for issues out of their control, they maintained providing good customer service. If you choose this team, you will not be disappointed. Vr Brian

We had 7 doors replaced with amazing service from initial salesman to the installers. We were kept up to date throughout the process and during the installation. The installers were non-intrusive, kept the work areas clean and tidy while ensuring we knew what the plan was for the 3 days they were onsite. Were open to questions and had all the answers relating to our installation and next steps. Alex and Kihei were professional and friendly throughout the installation of all doors
Will use again and recommend to all who ask

Earl, Cole, and Scott were amazing! They were so kind and professional. They were nice enough to drape our furniture to keep it clean, and they cleaned up extremely well when they were done. I highly recommend this company and crew!

Will the replacement windows be installed from the inside or outside?
The majority of our replacement windows are installed from the outside. In some situations, it may be necessary to install from the inside. On the day of installation, your installation expert will assess your unique situation and explain the process that will best suit your home.
Do you install replacement windows year-round? If so, will I lose a lot of heat/cooling at the time of installation?
Window World installs replacement windows year-round. An average installation will take only one day. Our crews install one window at a time and are trained to do what they can to minimize heating/cooling loss. The energy savings from your new windows will recover any incremental energy costs incurred during their installation many times over during their lifetime.
How can I prepare my house for my replacement windows?
Please take down curtains, blinds, or any other window treatments. Security sensors should also be removed and turned off by your security company. Please provide our installation expert with a clear path to the window(s) being replaced by moving anything that may be in the way. It is also advisable to remove all wall decorations from the walls close to the windows as they may fall during removal or installation.
How long will it take to get my replacement windows? How much time should I allow for the installation?
Generally, replacement windows can be installed within 4-8 weeks from the date that the final measurements are taken. The type of window being installed and type being removed helps determine the amount of time needed to complete the job. On average each window takes about 30-60 minutes. Trim work and cleanup will require additional time to complete. An average job will take a single day.
