A warranty concern after construction: what to send and what to check

Find the promise that applies to the concern

The YKCA Warranty page does not announce one universal warranty period. It explains that terms depend on the written agreement and the products involved. Start with the contract, any relevant change orders and manufacturer documents. Keep them together rather than relying on what you remember from an early conversation.

Separate installation concerns, equipment concerns and unfinished items identified during handover. They may require different records or contacts. A manufacturer’s product warranty does not automatically describe the contractor’s labor obligations. CSLB advises consumers to get offered labor and material warranties in writing.

Describe the observation without deciding the cause

Record what happens, when you first noticed it and whether it is continuous or intermittent. Safe photos and a short timeline can be more useful than a guessed diagnosis. Include the project location and the affected work so the concern can be connected to the relevant agreement.

For example, “the cabinet door began rubbing after handover” identifies an observation. It does not yet establish why it changed or who must correct it. Avoid altering the item solely to prove a theory. If an immediate hazard exists, address that through the appropriate urgent channel rather than waiting for routine correspondence.

Make the review request specific

Ask what information is needed, whether an assessment is appropriate and what the next step will be. Provide access constraints and a reliable contact. Do not include sensitive documents unrelated to the concern or assume that submitting a request creates an appointment.

If equipment is involved, provide the model and accessible identification information. Do not remove electrical covers or dismantle equipment to obtain a photograph. Existing installation paperwork may already contain the information needed for the initial review.

Keep a simple resolution record

Save the date of the request, information supplied, response and agreed follow-up. Distinguish an acknowledgment from a coverage decision and a proposed appointment from completed corrective work. If more than one party is involved, record which issue each is reviewing.

Use the Warranty page’s checklists to keep the discussion organized. The article does not expand or narrow contractual or statutory rights and does not decide a particular claim. For a disagreement, rely on the actual documents and appropriate advice. The practical first step is a reviewable description with the relevant written terms attached.

Keep the next steps clear
