Renovating has actually two functions. One is about renewal and makes sure that what is old or damaged will be renovated and be as new. The other function is change or expansion. Another Bathroom, wall, new floor, Wallpaper, Kitchen, tiles etc. If you have good hands, you can try and Do It Yourself, but it is recommended to have a professional doing the jobs, which in the end will save money, time and end with better quality. Still, you always have to watch out for pitfalls and unnecessary payments for material or work a so called professional might include in his bill in the end. Make sure you both agree on what to be done and how, prior to the beginning of the job.
