Walk through each room with the installer before signing off, in good light if possible. Check that the carpet lies evenly without obvious ripples, that edges are neatly trimmed and secured, and that seams are as discreet as the product and room layout allow. Look closely at doorways, transitions to other flooring, corners and any stairs or landings, where finishing details are especially noticeable. A seam may be visible to some degree depending on the carpet construction, colour, lighting and direction of the pile; the aim is a sound, tidy finish rather than an assumption that every seam will disappear. Ask the installer to explain any feature you are unsure about and raise concerns promptly while the work and site conditions are clear. Also confirm that door clearance and thresholds work as expected, and ask how to care for the new carpet during the first days after installation. The appropriate fitting method can vary by product, so avoid judging a technical detail without asking why it was done that way. Before the job, agree who is responsible for furniture moving and old-carpet removal, and what the quote includes. If anything needs attention, note its location and discuss it with the installer before the installation is considered complete.
