Dartmouth Building Supply is your Andersen After-Sale Service and Repair source in Southeastern Massachusetts and Rhode Island. Unlike the big boxes, DBS services what we sell. Our customers have peace of mind knowing that their Andersen windows or patio door are backed by an industry leading warranty.

Our professional, factory trained, and certified service technicians provide superior service and use only genuine Andersen Windows parts. We will determine if your issue is covered by Andersen’s Parts and/or Labor warranty (labor included on sash or panel replacement within two years of manufacturing date) and submit a claim on your behalf. We service all Andersen Windows, whether or not they were originally purchased from Dartmouth Building Supply, including repair or replace items not covered by Andersen’s warranty, at reasonable rates.
