Questions to Ask Your Tradie

• are you insured and can you provide public liability and employers' liability certificates?

• will you provide a written assessment of the flue condition and recommended work before starting?

• do you recommend a simple cap, waterproofing or a full relining for my chimney and why?

• will you need scaffolding or powered access and how will that be charged and arranged?

• what guarantee do you offer for work such as waterproofing, flashing and cap installation?

• how will you protect tiles, gutters and interior ceilings and deal with waste and dust?

How to Avoid Surprises

• confirm safe roof access and point out fragile tiles, slates or valleys before work

• arrange nearby parking or let tradie know if a scaffold lorry cannot access the street

• tell the tradie about loft insulation, nesting birds or asbestos concerns in old chimneys

• agree on waste removal and where debris will be left so clearance costs are clear

• check for conservation area or listed building restrictions before booking major works
