Can you substitute materials named in the contract?

Work it through

You're the contractor. Pick what you'd do, then see how each choice plays out.

1. AContact Sarah, explain the backorder, present the Pella alternative with specs comparing both, and get written approval before substituting
   Correct

   Material substitution without homeowner approval is a contract violation. Even if the substitute is equivalent or better, the contract specifies the original material. Written approval protects you from 'I never agreed to that' disputes. Present it professionally: here's why, here's the alternative, here are the specs, here's the cost impact (if any). Let the homeowner decide.

2. BSwap in the Pella windows — they're the same quality and she'll never know the difference
   Wrong

   Substituting specified materials without consent is a contract breach regardless of quality equivalence. If Sarah notices (and homeowners often do), you've destroyed trust. If she complains to the MHIC, you have no defense — the contract says Anderson, you installed Pella. Material substitution without written approval is one of the most common and easily avoidable contractor complaints.

3. CWait the 8 weeks for the Anderson windows — the contract is the contract
   Honorable but impractical

   Strict adherence to the contract is safe, but an 8-week delay has real costs: extended project timeline, crew scheduling disruptions, and a frustrated homeowner. The professional approach is to present options and let the homeowner choose. Documenting the backorder and offering alternatives shows you're both honest and solution-oriented.
