I wish I had found Derek earlier in my project. I had him install 2 doors and do the finish carpentry. I would have done well to use him for my framing too. We will be using his services in future for more projects.

General Carpentry

I’m so happy that we chose to hire Derek. We had been putting off installing our bedroom doors for months and months and he installed them with no problem at all. I would hire Derek again in a heartbeat.

Door Installation

After unsuccessful attempts at installing a door, we caved in and reached out to Derek. He was able to identify the problem and correct it successfully. He demonstrated a level of professionalism and experience that was much appreciated.

Derek responded quickly. The day of the repair he was on time and came prepared. He was very professional and even gave me advice regarding my other door. He was quick and competitively priced. I would STRONGLY recommend hiring Derek!!
