Porch Installation Guide

The porch can be located either in front of the house or at the back and is at street level. This will depend on the architectural design of your home and the space around it. A porch is defined as an attached section of the house which has a roof and allows outside air to flow in. The cost of building a porch can range anywhere from $200 to $30,000. Cost-effective porches can be built with either wood or concrete.

    As with any other addition to your existing residence, the new porch must seem like an extension of the house and fit in with its overall style.
  1. 1.First Step

    A building permit is required for most accessory buildings such as garages, sheds, patios, and porches. In some cities, height regulations may apply to these. So, the first step will be in obtaining a permit after completing the necessary formalities. Once this is done you can proceed with the construction process.


    Planning and preparation is key to constructing a durable porch. Measures to prevent accumulation of water under the porch and ensure air flow in this space must be incorporated in the design. As with any other addition to your existing residence, the new porch must seem like an extension of the house and fit in with its overall style and theme. If it looks radically different, this addition will have been a massive waste of time and certainly not a step forward.

  2. 2.Tools and Materials

    The right tools and materials are necessary to get a porch installed just the way you want it. Nails, screws, clamps, cement, water, sand, patio board, a hammer, tape measure, a drill with different bits, and a saw are just some of the things that you will need. You will also have to select the type of flooring that will accompany your new porch.

  3. 3.Installing the Porch

    You can place stakes where the four corners of your porch will be. If you will have stairs leading to your porch, you must place stakes to mark their position too. The next thing to do will be to place a ledger board at the spot where the doorway will be. Once the marking is done, the work of digging holes in all the corners follows so that the cement can be poured in with the help of foundation tubes. Posts must be inserted into these and left to dry overnight. Anchor caps can be secured on to the posts the next day and joists laid out in the center towards the exterior of the porch. Patio decking can be installed by dividing into segments the whole area to be covered. Railings can be added later.

  5. 4.Priming and Finishing

    The porch flooring must be protected against dimensional changes brought on by changes in the moisture content. Ideally, some finish must be applied to the flooring before it is installed. Water-repellant sealer is the product of choice for this purpose. Following installation, an oil-based porch enamel can be applied to the surface of the floor and any other exposed portions. The advantage of using an oil-based finish is that just one coat will usually be sufficient and this translates into savings in correlation to time and effort. You might want to toss in a lattice skirting around the porch top prevent any animals from accessing the space and turning into a nuisance and making your porch their new hang out spot. This will also prevent any debris from accumulating in this space.

  6. 5.Maintenance Tips

    The kind of maintenance and care required for your porch will depend on the type of flooring used. Wooden porches, if stained, can last for many years. The next best thing to staining would be painting which can then be redone whenever there is any chipping or other damage. Termites and ants must be prevented from damaging your porch with the help of bug repellants. If you can afford it, the best option is to hire a professional exterminator to do this work. Putting in a screen can help you keep out birds, mosquitoes, and bats as well as provide a sense of security and comfort.


    Following these guidelines and keeping it simple can help you install the porch of your dreams in no time at all.
