Almost all DIY projects are pretty easy and self-explanatory. Most people can paint a room, clean storm windows, and make minor repairs. Be careful not to overextend your actual DIY abilities in more complex areas. Unless you really know what you are doing, you are likely to have trouble (and encounter danger) with projects such as DIY electrical wiring and DIY sewer line replacement. Call an expert!
Never, ever attempt to make repairs to your home's wiring unless you know exactly what you're doing. Things might look neat and clean, but you won't be able to spot problems once everything is patched up. An electrical fire will demolish your home almost instantly, so consult the professionals if you don't know what you're doing.
Home improvement is often a daunting task. This is because of the time and the amounts of money required. However, it doesn't have to be so bad. If you have several projects in your house, divide them up into several smaller DIY projects. For example you may want to redo the entire living room. Start simple, by just replacing the carpet, and before you know it, your living room will be like new.
If your sink is letting rusty water out and it will not drain, it is mostly likely because of the biological scum and grease that is built up in the pipes. You need to have your drains professionally cleaned, allowing maximum flow through your drains. Your drains must be open completely.
Watch out for decreased levels of intensity in the water flow in your bathroom. This can be a sign of calcium or mineral deposits disrupting water flow. If spotted early enough it may be possible to remedy this without having to replace the pipes.
