When you need to replace a lock, you can opt to replace the entire assembly, or you can just replace the cylinder. The cylinder in the lock is what actually initiates the locking action. Changing out the cylinder of a lock is enough to preserve your security if you've lost the keys to the door. If you're upgrading the lock for added security or to make your door look better, replace the entire unit.
You should make a list of everything you need before heading out to a home improvement store. Creating a list will allow you to only make one trip to the store instead of many while keeping you organized at the same time.
When thinking about home improvements for areas with plumbing, like the kitchen and bathroom, consider replacing the walls with something more water resistant. Water resistant wall board, also referred to as "green board" to contractors, is better able to withstand wetness and humidity. Additionally, the material is treated with a special chemical that can inhibit the growth of mold, a common household allergen and toxin.
Start your project by writing a list of steps you need to take, and then get this list looked over by someone in the know. Even if you have to pay for the contractor to look at your list, it will be worth it to make sure you haven't missed an important step or supply.
Before you begin a landscaping project around your home, discuss any drainage issues with your neighbors. You will want to get rid of all water from your property. Often the convenient way to do this is to dump it on your neighbor's property, but they are not likely to be happy with this! You can coordinate drainage plans but you will have to communicate with your neighbors first.
