Bellows Construction has been delivering high-caliber projects for over a century and it wouldn’t be possible without the dedicated support of our diverse, loyal, and skilled subcontracting community. We take pride in the established relationships we have cultivated with our subcontractors but are always looking to expand our network with new relationships. For a streamlined process, we use Tradetapp for prequalification and Building Connected for bid posting. To begin the prequalification process, please send a request to and one of our estimators will be in touch.
