"Our original siding was 34 years old. They stripped it off in a few hours and replaced it with perfectly installed James Hardie fiber cement siding and trim. We now have a brand new house! Ernest and everyone we had contact with from GS were very patient, service oriented, and concerned for our satisfaction. We would recommend them unconditionally."

"They put an addition in our warehouse to accommodate offices, a dark room, and screen wash room. Each part of the project was very well executed in a timely fashion. Each area required many different things and they were able to handle it all with ease at a very fair price. I would highly recommend this company in the future."

"They installed windows for us. We found one window that was barely cracked. They came right back out and replaced it right away. The windows are very high quality and they are easy to clean. It so nice to have the new windows!"

"We had several projects to be completed involving various skill sets and one that required some ingenuity to resolve some installation issues. Ed was equal to the task and completed each of the projects to our total satisfaction. His cost was quite reasonable. We will most likely use him for some other forthcoming planned projects this Spring or sooner as needed."

"Great service and great prices at Wallaby! I had called several companies to get a quote and Casey gave me the best one. Only about half of the other companies I called were able to get a large enough window in the first place. Casey was diligent, knowledgeable, and easy to talk with. I met a couple people on his team - Angi and Adrian - who were both courteous and skilled professionals. Adrian who got the job done quickly and cleanly. Thanks to everyone at Wallaby Windows who helped make this easy and affordable."

"Great sales rep Mike, Great installation and great windows! This was a small job of just 2 window replacements. But they were all friendly and very professional."
