Thus, if you do the project by yourself, that’s more money in your pocket. But first, you need to be honest about how skilled you are.
Although saving some money sounds excellent, you may still feel a bit overwhelmed about taking on the entire job yourself. If you want to do it yourself, think of dividing up the project and working on what is within your skill level and timetable, and save the more challenging projects for a contractor.
Just make sure to tell your contractor about that you’ll be working on, to avoid confusion later. Below are several easy DIY projects:
- window and baseboard trim installation; save $150 to $250
- Painting 200 square feet of walls and trim; save $200 to $350
- Towel bars and shelf installation; save $30 to $100 each
- Toilet installation; save $200 to $500
