Our nerdy technicians have been fully trained by our manufacturers and they are fully qualified to provide
warranty
service on all of their windows, doors, siding and more. This includes numerous issues covered by the
manufacturers'
warranty, including operation adjustments, glass replacements, and more. If RenoNerd (or its predecessor St.
John
Windows and Doors) installed your products, you know that we can amend any unforeseen issues. But we also
have vast
training that enables us to repair issues by windows and doors installed by other companies – even if you
don’t know
who first installed your products, there’s a good chance RenoNerd can fix your issues.
