Fiberglass windows are a popular choice in Arizona. While more costly than vinyl, fiberglass windows can be easily painted or stained, can be slightly more energy efficient than vinyl windows (depending on the specific window chosen) with durability that withstands year after year of Arizona sun.

Fiberglass windows are impervious to rot and termites, and they have a longer lifespan than vinyl windows.

They can also mimic the look of wood, a design feature important to some homeowners, and can have a thinner frame than vinyl, allowing more light and visibility into the home.

What is Fiberglass? An extruded material of polyester resins impregnated with strands of glass into a shape that can be molded and shaped. Made from approximately 60% glass and recyclable when removed, fiberglass windows are an environmentally friendly choice.

“We would recommend him to friends and family in the future. We didn’t require his services for this particular job but his customer care is outstanding!

We called him to replace a window in our home on a Sunday. Not only did he get back to us immediately, he let us know that we contacted the wrong company and referred us to a company that could help us. He explained that if he did come out and do the job he would replace the entire window and what we actually needed was just a glass replacement, saving us a lot of money. He was professional and very easy to deal with.

Even though we didn’t use him – based on his integrity, professionalism and customer care, we would recommend him in the future.”

The removal of the windows and installation of the doors was done in a very professional manner. The two technicians kept the area very clean. Debris was removed during the process. The installation was very professionally done. The doors work very smoothly. The sheetrock/plastering persons did a very good job. Put plastic down to protect the doors and the floor in the work area. Plaster finish matched the existed finish quite well. The stucco person likewise protected the doors and patio with plastic sheeting. Work was done well and finish matched the outside stucco finish well. Sal kept me informed of the timing the project several times. I knew when the personal would be arriving and who they were. I am very pleased with the whole process.
