There is no substitute of time so it cannot be ignored in any condition. Market reputation is sufficient to reveal about the plumber that his promptness is fit for you or not. Either you will get your work done on time or you will wait for the whole day for arrival of your plumber. Price also affects the selection of the plumber because after determining the problem it is only plumber who will provide you the estimated cost of material and his remuneration.
Considering the time limitation it may be possible that you are willing to pay overtime charges to finish the work in short time. Different kinds of labor cost are charged in market but mostly hour rate is preferred as compared to total project consideration and this is mostly done to save the time. If work is not according to standard and time is wasted by the plumber it is very easy to replace the plumber in hourly base work agreement which is not quite simple in project agreements. Comparative labor cost for quality work within preset time make important terms in agreement with the plumber.
Either work is new for the newly constructed building or it is related to normal repair work, quality of work is important but selection of material for replacing the material and other parts for removing leakages are also important in this regard. If your plumber is well skilled person and keeps the full knowledge about the quality of the materials to be used in his work then his guidance will make easy to decide which accessories are suitable and which material is more appropriate for your purpose.
All matters are only valid when your plumber gives you full guarantee of his work done because with guarantee your satisfaction level increases and it also increases the goodwill of the plumber which makes him credible for you for next time and for others as well. Good plumber will always provide you detailed bill along with invoices of his purchases of material used in your premises from registered seller.
