- KBKent Brown1 day ago5.0Everything was as advertised. The install crew came in and completed the project efficiently and professionally. They kept me informed during the various stages and were very poilite. The intregity of the windows were as expected ad described during the sales process.
- DMDavid MacinnisMay 11, 20265.0Wanted to give a shout out to Will and the crew from Carlsbad who installed multiple windows and they went above and beyond to make it smooth and quick for us.
- SDSaid E. DawlabaniMay 7, 20265.0Art was as professional as they come. Even though our windows were replaced over 10 years ago, Art and his helper demonstrated a degree of professionalism and care that I have rarely seen with other vendors. They even agreed to take back some of the frayed screens with them for repair. Normally, a customer has to drop screens at their warehouse for repair. This is what I call going above and beyond to keep a customer happy and loyal. I have recommended Window World to all my neighbors and friends and will continue to do so. Very happy customers.... 10 years on....
- CICarmen IslandMay 5, 20265.0I had a great experience with Art Galindo when he came for an inspection on a service call. He was on time, knowledgeable, and professional.
- LOLj OptionalApr 28, 20265.0I ordered a new sliding glass door with a doggie door insert. To be honest, it was a bit of a rough start with this company. I was told it would be 4-5 weeks, but it took 11 weeks before installation. I ordered a 9x12 doggie door but received an 8x10 doggie door instead. Installation went well, but overall, I was disappointed because I didn't receive what I had envisioned. I wrote a review of my experience, and within an hour of posting it, the owner of the company reached out and offered to correct the mistake. I agreed and they were able to order a new glass panel with the proper size doggie door within about 2 weeks. It was just installed yesterday, and I couldn't be more thrilled with the results. A beautiful new sliding glass door that locks from the outside and has the perfect size doggie door insert for my dogs. I love it! I really appreciate the owner, Gene, for turning this unhappy consumer into a very happy consumer!!
