Be sure to buy pressure-treated lumber. It is more resistant against deterioration and termites. However, it is still susceptible to dampness and rays of the sun. It is possible to preserve the wood without changing the color. You can utilize a clear wood stabilizer which has a ultra-violet protector. It adds new life to the surface of the wood and protects the material from extreme weather conditions. Apply another coat for better protection. Let the deck dry for two days prior to applying a sealant.

Building a new veranda is more complicated and requires a lot of expertise. If you have drafted a layout and have your budget ready, begin with the layout. You can opt for the 3-4-5 scheme. Draw a four feet line parallel to the house wall. One of the points will be stake A and the other is stake B. Connect another line to pole and let it run perpendicularly to a point three feet’ away. Connect the line to stake C. You will come up with a square corner with a five foot distance between pillars B and C. Make use of the stakes and strings to finish the framework of your portico. Accuracy is particularly important.

Determine the location of the posts based on dimensions in your outline and mark these points with poles. Post holes for tractions should be a minimum of three feet in depth and 12 inches in width. Deeper holes may be needed depending on ice conditions in your area. There should be a gravel base of two inches in the hole. Insert a concrete form with an eight-inch diameter. Fill the form with ready-mix concrete and drop a 4×4 metal weight into the middle of the concrete. Make sure that saddles are even and let the concrete dry overnight. Post height is measured by distance from the top of the floor to the base of the saddles minus thickness of the decking, trusses and beams. Attach the floor joints. Install the deck, railings and stairs.
