I couldn't be happier with my renovated space. I highly recommend Partner Construction for any home improvement needs!
I found Partner Construction, Inc and Michael through Angie's. I needed Doors and Windows installed in the condo that I just purchased. They completed the work in two days and they hauled the old windows/doors and cleaned up after themselves. Michael was great, very communicative, almost always available to discuss next steps and easy to work with. I would highly recommend him and his subs that he works with. Will be coming back for other home improvements.
Partner Construction did a fantastic job replacing our old cracked and crumbling brick patio with a new concrete patio. And, when the bricks were removed, it was found that the metal supports were rusted and they replaced them with new wood posts. The team who worked on our patio was very prompt and professional. The patio looks great and they left our yard very clean.
