SeaMax Building Consultants works out of Marshfield, putting windows into houses across the South Shore and Cape Cod. Its Houzz profile leads with window installation and custom windows, and the certifications behind that are specific to the work: AAMA Installation Master, Andersen Window Installer, OSHA 30. Houzz also lists an unrestricted Massachusetts construction supervisor licence for the company. Alongside the windows it offers owner's representation — standing in for the homeowner on a project rather than doing the building. Three projects appear on the Houzz page: a Falmouth deck, trim in New Seabury, and a job on Nantucket. For a South Shore or Cape homeowner pricing out a window replacement, those installation certifications are the concrete thing to go on. Ask to see finished window work nearby, and settle early whether you are hiring the install or the owner's-rep role — the profile offers both.
