Agree a staged payment schedule tied to completed milestones, and hold a small retention until snagging is done. - Get it in writing: an itemised quote with scope, materials, start and finish dates, and how any changes (variations) will be priced. - Be wary of a cash-only price or pressure to start tomorrow. Both are red flags for an unaccountable job. - Ask to see a portfolio of completed work like yours, plus recent references you can contact. - Check the credentials and registrations that matter for this work, and that they are current. ## Contact - Phone: 07308 504678 - Website: http://www.fmbuilding.co.uk --- Source: MyTrustedTraders, https://mytrustedtraders.com/traders/fm-building-ltd-2 Real public evidence only: every figure traces to a named source and is cross-checked.
