Homeowners have been advised to thoroughly check the credentials of professional kitchen renovators before paying for work.Domenica Marchetti of the Washington Post noted that a full kitchen remodel can compare to the cost of university tuition.It is, lets face it, an expensive undertaking and one you should consider thoroughly, long before you start wrestling with whether you are going with granite or soapstone, hardwood or tile, said the writer.Indeed, it was suggested the homeowners should first check the qualifications and credentials of possible contract workers before agreeing to anything.This could involve looking at whether they are a member of a trade association or examining their portfolio of past work, the Post said.Meanwhile, Rebecca Kolls, senior director and consumer strategist of homes and gardens at Iconoculture, recently told NorthJersey.com that homeowners can streamline their kitchen sink area by removing clutter and using multi-functional products and appliances.
