How to Choose the Right Builder in Portsmouth

Before hiring a builder, make sure you:

  • Read customer reviews – Check how past clients rated their finish, communication and schedule.
     
  • Check credentials – Is the builder qualified, insured, experienced with your type of job?
     
  • Compare multiple written quotes – Get at least three quotes to compare scope, breakdown of labour/materials/trades and timeline.
     
  • Inspect the quote’s detail – Look for what’s included: materials, waste removal, scaffolding, project management, trades coordination.
     
  • Beware very low quotes – If one quote is far below typical ranges, it may exclude key works (structural, finishes, access, delays).
     
  • Check project timeline and trades involved – Large jobs often need multiple sub-trades; ensure the builder coordinates and includes them in cost.
