Homeowners should carry out thorough research to ensure they receive a reliable and efficient service when paying for a professional kitchen renovation, it has been suggested.According to a home improvement article in the Guardian, even simple changes like having a kitchen sink installed or a kitchen tap repaired can become troublesome if the tradesman is dishonest.When friends and family cant recommend anyone, its hard to know where to look sticking a pin in the listings in local business directories to find a firm is not recommended, it said.Homeowners were therefore urged to use the Trading Standards website to find their local Builders Register which includes a list of recommended plumbers, roofers, electricians and other traders who have undergone a strict vetting procedure.The newspaper also advised using commercial directories like RatedPeople which claims to be the UKs largest trade recommendation service, where consumers can find and choose traders in their area based on what others have said about them. Meanwhile, speaking to yourhome.ca last week, Tyler Hershberg of Canadian development firm BSaR Group of Companies argued that appliances and fixtures should not clutter the space in smaller kitchens.
