If you encounter any issues with the IKEA materials you've supplied, such as missing items or damages, it's important to inform us as soon as possible ( preferably at least 1 week ). Ensure you have all materials in advance to avoid delays, as waiting for missing items to arrive can push back the installation schedule. While we can offer guidance on resolving these issues with IKEA, any delays or additional visits required from our side may incur an extra fee to cover our costs.
