Master Plumbers understand how important it is to provide an accurate estimate of the work required and exactly how much it will cost. So we will carry out a full assessment and let you know what needs to be done and how much it will cost for free. And if additional problems arise whilst we are working we will provide a further estimate before continuing. Customers will not be charged for parking, the time plumbers spend traveling to jobs, the London congestion charge or any other hidden fees. No matter how small or large the job Master Plumbers guarantee the highest standards of service. Any problems arising as a result of a faulty installation or repair work, and which fall within the guarantee period, are a priority & are be dealt with as it is convenient for you. Problems which fall outside the guarantee period are also a priority and although the work will be chargeable it may be available at a reduced rate at our discretion.
