Product Description
Exact blind model, finish, control type, and mounting method. Use manufacturer codes to remove ambiguity and enable warranty claims.
A focused addendum clarifies product specifications, protects both parties against scope creep, and documents price or timeline changes without reopening the full contract. It creates a concise record that is easier to sign, store, and reference than multiple informal communications.
Each party should keep a signed copy; contractors retain documentation for billing and warranty purposes while owners keep copies for inspection and future resale records.
