Start with the purpose of the space

Baseboards, casings and mouldings help connect doors, floors and walls into a cohesive interior.

Materials and design choices

Profiles should complement ceiling height, door style and the architectural character of the home.

Questions to ask before work begins

Discuss material choices, corner details, caulking, filling and whether finishing paint is included.

Budgeting and scheduling

For trim & finish carpentry, build a written scope that identifies preparation, material allowances, installation, finishing and cleanup. Prices vary with the existing condition, access, product selections and the amount of work involved. Leave room for unforeseen conditions rather than relying on a single generic price per square foot.

How to compare contractor estimates

Compare the scope, not just the total. Ask which materials are included, who handles disposal, whether any trade-specific permits are needed and what changes require approval. A clear estimate helps avoid misunderstandings once trim & finish carpentry work is underway.

Preparing your home

Photograph the space, clear access, protect valuables and discuss dust, noise and daily access with the contractor. Confirm the sequence of work and when you can safely use the area again.

Final walkthrough checklist

Check the agreed finishes in normal room lighting, review transitions and edges, ask about maintenance, and document any touch-ups. Keep product and care information for future reference.
