I had an outstanding experience with Garreton and his team. They renovated my 1940's basement and transformed it into a modern show piece. They listened to what I wanted and made my vision come to life. They were courteous, communicative and professional. I highly recommend them. They do quality work at a fair price.
Details: Residential • Less than 500 sq. ft. • No, I will not be adding structural or weight-bearing features to my basement • No, I will not be modifying or adding living space to my basement • No existing plans, but have a good idea of what I want
Basement Finishing or Remodeling

Working with GSS Development Group was professional every step of the way. It was a challenge securing a contractor to do a full completion and finishing of our basement that would provide a detailed estimate of the work we were looking to do. GSS provided us an estimate within a matter of a few days. They kept us updated on every stage of the process and stuck to the estimated timeline of completion which is rare with renovation projects. Even on days we were not on site videos and pictures were provided as updates. It was nice to be able to trust their workers in our home as well.
There was even a moment where we changed our mind on a minor piece of the layout we wanted and they were accommodating on making that change without making us feel bad. In addition to that, they confirmed things we wanted & even recommended certain things we originally said we did not want but actually was necessary.
I appreciated the timeliness, communication and professionalism in working with GSS Development Group. Once the project was done they ensured we were satisfied & made any minor updates needed immediately.
Everyone fears a crooked contractor that prolongs a project or rips you off. From Day 1 I knew this would not be the case and I’m grateful to have worked with GSS. I will be keeping them in mind for future projects & recommending.

GSS Development Group contractors did an amazing job. They were polite, professional and worked very hard. They performed quality work while installing my AC Split System. I highly recommend them for any projects you may have.

I really loved the outcome of the renovation. Done in a timely and orderly fashion. Constant communication and overall a perfect home make over. Many people who saw my home previously and came over recently is in shock of the difference. Perfection!

Exceptional service and exceptional results. Our bathroom remodel experience was outstanding from start to finish. The team demonstrated a high level of skill, creativity, and professionalism, turning our outdated space into a modern, functional, and beautiful oasis. Their guidance in selecting materials and designs was invaluable, ensuring we achieved the perfect look within our budget. The project was completed on time, and the final outcome surpassed what we envisioned. We couldn't be happier with the outcome and highly endorse this company for any remodeling needs!
