Terrence Caldwell

Loved working with Astonin. They managed the renovation of my small restaurant and were always transparent, quick with their work, rectified any shortcomings, and overall very trustworthy and really nice guys. They used a great project management system that allowed me to see the work being done, accurate estimates and costs. They were also very communicative throughout the project, always checking in, and responding immediately to any issues that arised. Overall the project finished on schedule, budget, and met all of our expectations.

We had an ongoing problem when it rained with water flooding our garage. I found a contractor who did a brilliant job of installing a long drain and sump pump leading underground to the front of the house and out onto the street. They were amazing contractors who were ultra professional, polite and cleaned everything up. They were also reasonably priced. They perform other type of construction work from painting, plumbing, electrical, roofing, to kitchen and bathroom as well. We will be using them in the future to build an ADU in our garage. I highly recommend Astonin Construction.

Astonin did an incredible job coming up with a solution and redoing my roof deck. The cost of creating a waterproof fiberglass floor was about 40% less than re-tiling. The workers were professional, kept the floors covered at all times, were respectful and listened to feedback. The job was done very well and on time. Thank you guys very much!

Astonin Construction and his team did an amazing job removing the outdated paneling around my stairwell and installing this premium cable fencing. Was very professional, great at communication and thorough — I highly recommend!

Alex Lynchosky

I worked with Astonin to do a redesign of my house. It included lacquering the doors to a lighter color, installing sound absorption panels on a large wall, and repainting the entire house, trim included. They were very professional during the process, providing frequent updates and ensuring everything was up to standards. In the middle of the project a large storm hit and it exposed a leak in one of my windows! Astonin was able to quickly find the leak and mitigate the damage before it got too bad. I am currently working with them on the long-term window repairs, and they've been great so far! Great quality, professional, and responsive. I highly recommend doing work with Astonin. I know I will!
