I graduated from Maine Maritime Academy and currently do have a day job but am looking for some side jobs for extra money. I built an addition on my house and found that I have quite a bit of talent in all areas of a house. I’ve installed my own heat pumps in my home, I’ve poured slabs, did all of the plumbing, electrical, insulation, drywall, flooring, trimming, doors etc. I learned a great deal and would like to put that knowledge to use.

"I called Octagon the day after we had an upstairs water leak. The next day, Octagan had scheduled a technician to assess the damage and set up the mitigation solutions to dry out the damage before mold could set in. Everyone from Octagon was friendly, professional and very responsive. If you need a fast, reliable and effective response, you will find it with Octagon!"
