What is the estimated timescale to complete the project?

Ask your Harrow builder for a detailed schedule. This should include important milestones in your project, like site preparation, foundation completion, structural framing, roofing, installation of utilities, interior finishes, and final inspections.

Do you provide guarantees or warranties for your work? Most building contractors and companies in Harrow provide warranties covering their workmanship and materials for a specified period, offering reassurance that issues will be addressed post-project.
