Our Window Installation
Installation of replacement doors, windows, shutters, and vinyl siding are not tasks for the casual handyman. These large-scale projects require the tools, skills, precision, and training that only comes from an experienced Window World home improvement specialist. Windows and Doors specifically must be installed so that they float perfectly within the allotted frame. Without a master’s level of precision, replacement windows and doors can be fitted and installed unevenly, created a lopsided final product. To ensure the highest quality installation job, it is best to put the project in the hands of an experienced Window World professional craftsman.

Cant speak highly enough about the whole Window World crew especially Tor. He was very detailed with the installation of our new windows and we feel like we have a new house. They showed up on time, did an amazing job, and cleaned up leaving everything like new. Thank you!

I went to many companies on the island and priced them all out and window world was by far the lowest price. Brent was very professional and it was all a smooth process. Updating review later with pictures of window treatments. Highly recommend!

I had an exceptional experience with Window World of Oahu. From start to finish they were very professional and couldn’t be happier with the finished results. I had a new sliding door and 7 new Windows installed. The price was great and the lifetime warranty knowing I wont have anything to worry about in the future was a big plus.

I had Brent out to my house to get an estimate on replacing 3 patio doors and some windows. He was very professional and couldn’t beat the price and the warranty. Saying I’m satisfied would be an understatement.
