I worked with the Octagon team to replace a floor that had water damage. Jeff and Sean in particular made the process easy and Sean did exceptional work! We have a young child and Sean went above and beyond to make us feel comfortable with him in our home and even respected nap time! No question about it, I will be using Octagon again!

Todd was efficient, communicative, and very helpful. He made sure I knew what to expect for my floor replacement, and then followed up to make sure I got what I wanted. When I asked to have one detail fixed, he got it taken care of immediately. Thanks very much!

Josh was an amazing project manager for Octagon. Despite some initial delays before he took over, he was able to pull it together and make sure the project was completed to his high standards. We're highly satisfied with the results.

Our finished basement suffered moderate water damage last summer. We hired Octagon Construction to handle the repairs after remediation was done by their sister company, Octagon Cleaning & Restoration.

Overall, we were pleased with the experience and results. Todd, the project manager, was very friendly and communicative. It was a bit tricky to work around the existing fixtures and coordinate access to the home, but we did not encounter any major issues. Todd was responsive to calls and texts and helped us navigate the more complex aspects of the project, including dealing with insurance and building inspectors.

We ended up hiring them for some additional renovations while we had them on site. The process for requesting additional estimates and change orders was convenient.

Working with Todd Golden and the Octagon team was a very professional and great experience. From the moment we were introduced, Todd made it a priority to explain everything and answer all questions we had for our kitchen rebuild. He constantly would text, call or show up on site to make sure everything was going smooth, right up until the final day of work.

I would not hesitate to recommend Todd and the Octagon team to anyone that is in need of their services!

Octagon Construction and Energy did an excellent job at my multi-unit property in Old Orchard Beach after a major sewage backup. They installed a solution to prevent future city sewer backups and also corrected electrical panel and code issues while onsite. Professional, reliable, and true to their word. I highly recommend them.

I had a water damage from an overflowing toilet on the second floor that caused damage to our kitchen below. Octagons team came in and helped us navigate the insurance system. They were able to quickly get my house back together. Kyle was very attentive and made the process very smooth. The crews that did the work were very polite and left a clean work environment. I was very impressed! I am going to hire them again in the spring to replace my deck!

Was recommended by their sister company.

They didn't keep there word. They didn't respect timeline, and furthermore set timeline expectations and then ghosted.

When you ask for them to make it right not with money, but with better communication and an immediate quote as promised.

They gaslight and push accountability on the client.

Be very careful. If they act like this now. Its a sign that if theres an issue. The office starf will act the same. Including lying instead of taking accountability.

My finished basement was flooded when my hot water heater leaked. I called Octagon. They came the next day. They removed carpeting portion of dry wall and insulation to prevent mold. The restoration was completed and very well done. I highly recommend Octagon They were efficient with great results.

Working with Octagon was an absolute pleasure! From start to finish, their team demonstrated professionalism, expertise, and a commitment to quality.

The crew was courteous, kept the site clean, and communicated clearly throughout the process. Their craftsmanship is top-notch, and the results exceeded our expectations. I highly recommend Octagon for any construction project—big or small!

When I called and a real person answered the phone, I felt relieved immediately. Octagon is a great team of people. Everyone knows what they are doing. The service was well communicated. Price was very reasonable. The job was executed exactly as described and right on time. Highly recommend if you want no nonsense and good work.

When we decided to refurbish a section of our very old house, we knew we were in for some surprises. True to form, the project morphed into a much larger undertaking once the team began work. What truly impressed us was how this company handled every curveball. From the first introductory conversation, their team demonstrated the highest level of professionalism, expertise, and skill. The project manager was excellent, keeping us consistently informed about both the expected—and unexpected—developments. The crew's attention to detail was exceptional, preserving the historic character of the house while seamlessly integrating modern updates. We are so grateful for their patience and guidance throughout this journey, and the end result is a home that is better than we ever could have imagined.
Octagon Construction truly stands out as a company that is trusted, thoughtful, and deeply customer-focused. We wholeheartedly recommend them to anyone seeking a high-quality, professional construction partner.

Octagon Construction and Energy of Windham, ME is a relatively new company and like many companies will experience ups and downs. We hired them to remedy the leaks on our living room and dining room ceiling as well as to fix the cause of the problem from the outside. Todd was our Project Manager and was easy to reach and worked hard with the insurance company’s adjuster. He coordinated the crews that did our work. The primary workers were all subcontractors. We paid Octagon extra for new lighting, insulation and to have the entire ceiling sheetrocked and painted. Todd tried to resolve all problems but when the painters came back several times to fix their paint job, we finally asked for a different paint crew, but were told that they were the best. We ended up hiring another painter who gave our ceiling and walls a clean cut look. Octagon was willing to pay for the paint and a couple of rollers, but we had to pay the painter for the five hours it took to re-edge the ceiling and walls and to repaint one wall. The electrician they hired did a great job! After some heavy rains, we are pleased that our ceiling is dry and hope it will stay that way. Despite the issues we encountered (there were more than are mentioned here) everyone from Octagon was pleasant. In our opinion, Octagon needs to remember that quality work needs to prevail even if their margin of profit has to occasionally shrink to adequately remedy problems.

We had a soot puff back from our non vented propane fireplace that required both extensive cleaning, ceiling painting and some wall painting. Octagon handled both the cleaning and the painting and we are very pleased with their work. Every one of their employees were personable and efficient and we would not hesitate to hire them again. Thanks again, Octagon! You made a painful experience much more bearable.

Short version - Todd and his team were professional and wonderful to work with. Every job will have a punch list when it is "done" - they addressed those items quickly. I would definitely hire them again.

Longer version - I hired them to do repairs after the remediation that their sister company, Octagon Cleaning and Restoration, did. Todd was thorough in his estimate and helpful with ideas about working with insurance. The job involved drywalling and repainting. The crew Todd sent was professional and personable. They did a good job of keeping me up to date on what they were going to do and when. They kept the jobsite clean. They did a great job blending the new drywall into the existing drywall. And our normally skittish dog loved them. I would hire them again.

Todd was excellent at keeping me up to date on what next steps were and the crews that fixed up my basement were quick and professional. I am very happy with the results.

Octagon added a half-bath to the upstairs of my small Cape Cod home. It was an extensive project, due to demolishing and rebuilding two closets in order to build out the bath. Although a couple of things required additional care, Alex Hoyt was excellent as the overall manager of the job. He was completely professional and very invested in the job being done to my satisfaction. He succeeded. I wouldn't hesitate to work with him again in the future.

Had a great experience with Octagon who oversaw the reframing of 11 windows in all sorts of different conditions on my older house. The work was quick and neat, everyone was friendly, price was reasonable, and I would gladly work with them again.
