Mission-driven company with strong values and supportive onboarding - Anonymous employee Costello Construction Employee Review

Costello Construction is a hard working company. They self perform over 30% of their work which means there is a lot of action. The comradery and team work is un matched with other companies. You truly feel like a team working together towards a greater goal. The majority of their buildings are complex and very architecturally pleasing drawings. No job is the same as the one before. Also, the benefits and salary are very generous as well. There is a ton of room to grow and be successful in the company. There truly feels like there is no ceiling.

Sometimes longer hours are needed depending on the phase of the project.

With 25 years in this industry, I’ve seen my fair share of companies—but few have stood out as remarkably as this one. I’ve always known this organization to be honorable, honest, and genuinely committed to client satisfaction, but now that I’m part of the team, I see firsthand what sets it apart. From day one, the senior staff have been exceptionally helpful and knowledgeable. Whether it’s guidance on best practices or simply lending a hand when challenges arise, they are always willing to support their colleagues and create an atmosphere of mutual respect and learning. There’s a real culture of collaboration here, where experience and innovation are valued equally. This isn’t just a company that gets the job done—it’s a place where people are empowered to do their best work, grow professionally, and feel proud of the impact they make. I feel fortunate to be part of a team that upholds such high standards and places a premium on integrity and service.

I have nothing negative to say!
