As the seasons change and our tastes become a little more defined, many people get tired of looking at the same-old-same-old in their homes. Not everyone is out to completely remodel their dwellings, but most are going to tackle a home improvement project or few. By following the tips below, make sure you are doing it right. br br Improving the air quality inside your home can be an invaluable home improvement for both your health and the resale value of your house. The first step would be to replace any old carpets or have them professionally cleaned, as they could be hiding contaminants, allergens and unpleasant odors. If your budget allows, install an energy efficient air conditioning system, secondly. br br Do not overlook the addition of storage space to your new or existing home. Most homes are substantially lacking in storage space. Add built in bookshelves to the living room or dining room. Turn a broom closet near the kitchen into a food pantry. Small changes and additions will really add up. br br Here is a simple way of fixing gaps at the bottom of poorly fitted interior doors. Sandwich a section of timber (cut to the width of the door) between two pieces of paneling. Leave each piece of paneling sticking out beyond the upper side of the two by two by about one inch. Slip the extension over the bottom of the door and screw each piece of paneling into place against each side of the door. br br For an energy efficient upgrade, replace your hot water heater with a tank-less model. The new tank-less heaters only heat the water as it is needed as opposed to keeping 50 gallons or more heated at all times. This change will help your utility bills and the environment. br br Bring in a professional to inspect the current flooring in your home, before investing in new hardwood floors. Sometimes, people find that they have hardwood under their linoleum or carpet that just needs to be refinished.
