To give an ordinary room a sleek and finished look, add some decorative molding. Molding is highly sought after by many buyers, and can make a room look more put together. Molding is surprisingly easy to install, and is fairly inexpensive. To really make your molding pop, paint it a color that compliments your walls. Building or buying a window box for windows in the front of your house is a very effective way to add color and visual interest to a drab exterior.A filled planter can be very heavy, so make sure that you use cleats to secure the box to the house. You can update the look by planting seasonal herbs, flowers, or grasses. Damaged, bent, or rusted metal railings are one of the most offensive eyesores commonly seen on older houses. For a modern look that doesn't upstage the classic exterior of your house, replace metal railing with richly textured wood supports.You can stain the wood a darker color or leave it natural depending upon the exterior color of your house. Use high-quality insulation around your plumbing system to prevent your water from freezing during this coming winter. Heat tape also works very well and is relatively easy to install, even if you're a home improvement novice. The tape plugs into your home's electrical supply and keep the pipes above the freezing point.Sometimes, improvements within the home can cause a disturbance. The best way to go about this would be to work on your project at designated times or when no one's around. Home-renovation projects are stressful enough. You shouldn't have the added pressure of dealing with other people in the home. Hunt down drafts in your house around your windows and doors, and seal them with insulation or weather-stripping to make your home more energy-efficient.
