Dear Sir/Madam. Please could you provide us with some more information regarding this or call the office with further details, we are not aware of any works that have progressed in the way you have described but rest assured are keen to keep tenants happy throughout their tenancies, in order to diagnose some rare issues is does take one or more contractors, especially if for example on a modern high pressure central heating system where issues can be water, plumbing, electrical or handyman issues, of course we would always aim to solve issues quickly and if a contractor does in fact carry out repairs that fall below our standards, or we are forced to instruct another due to this, the landlord would not then pay for the job to be completed twice. This would be an issue we dealt with at office level direct with a contractor and the landlord would still only be charged once. Please do not hesitate to contact our office with more details so we are able to ascertain what property and issue you refer too. Thank you.
