Sometimes you may be able to catch mistakes right away, other times you may not notice them until much later when it is much harder to correct them. If you use the wrong screws, you can end up with problems with the appearance, quality and strength of your addition. Take your time and don't rush at any time during the construction of your project. Take some time to lean about the different types of composite deck fasteners that are available. Learn why you would be able to benefit more from this choice of materials than any others.
If you decide to do the construction yourself, then you should consider methods that will make the task much easier for you. For example, if you pre-drill your holes you increase the amount of room your screws have to fit. This reduces the likelihood of them breaking and bulging. Avoid using screws that have a V shaped top. They are not as visually attractive as other screws and fasteners. Consider using hidden composite deck fasteners. They are virtually undetectable to the untrained eye. They are corrosion resistant, impervious to extreme hot, cold or moist weather conditions.
