How to Prepare for a Siding Installation

Installation of siding is a technical and precise method. But before any kind of siding can be affixed to your home, it must first be sufficiently prepared. The preparation technique will vary depending on what material you will use for the siding. Unless this is done in the appropriate manner, it can lead to numerous siding defects a few years down the line. In some instances, the manufacturer’s instructions should be sufficient for you to prepare for this necessary evolution in the proper manner. It is also a prudent idea to do some research on the topic so you know what needs to be done before the siding is installed.

  1. In some instances, the manufacturer’s instructions should be sufficient for you to prepare for this necessary evolution in the proper manner.

    1.Checking Off Each Step

    Permits and approval have to be sought from the concerned authorities before you can proceed with the siding installation. Each city has its own set of rules regarding the type of siding that homeowners can install and other related details. Checking up on these details and filing the relevant documents in advance can spare you any hassles later on.


    There are some general preparations that you will have to undertake on your property as well as some specific siding related preparations. The right preparation will ensure a longer life and greater durability of the siding. You will also have to look for a professional siding contractor if you do not intend to do it on your own.

  2. 2.Finding an Honest Contractor

    Seek referrals from friends and interview a few siding contractors before you decide on one. Ask them about the experience in doing similar work and look at some sample pictures of previously completed projects. Ensure that they understand exactly what you have in mind in terms of the color and material of the siding as well as the finish. Set up a payment schedule that both of you can work with and that is mutually agreed upon. You can also ask them about any warranties they can tie to their work. All these terms and conditions should be put into a written contract which can then be signed by both parties before any work is began.

  3. 3.General Preparations

    You will have to trim any trees that are close to the wall where you want to put up the siding. Then remove all the lawn ornaments, furniture, garden hoses, and other such items from the area. If the wall has a mailbox or satellite dish affixed to it, this will have to be removed and can be later installed after the work is completed. Since the siding installation involves hammering nails into the exterior walls, it might also cause some of those nails on the interior walls to pop through, so you must keep an eye out for this. Switch off the power to the exterior lights and remove any light fixtures that may be near the area which will have the new siding installed. You will also have to remove window shutters and frost boards under the eaves.

  5. 4.Siding Preparations

    Loose boards and wood trim must be secured with nails and rotted boards must be replaced. The wall over which the siding will be installed has to be first insulated with board. This is available in two by four sheets that can be connected together with a minimum number of seams. Some vinyl sidings have inbuilt insulation but most do not so it is a sagacious or smart idea to fill the cracks in with caulk.


    Since vinyl tends to expand and contract depending on the weather conditions, the measurements taken before installing the siding have to be precise. If there are obstacles like dryer vents or window trims, the siding must be adjusted around these so there is room for expansion. If the siding is wooden, the preparation should focus on locating an apt base for the panels to be nailed onto. Wood siding, which is to be installed horizontally, is easier than the vertical installation. If the siding is to be fixed to a masonry wall, furring strips will have to be put in and the siding can be affixed to these strips for complete support.

  6. 5.Proper Respect

    Experienced contractors are familiar with the different types of preparations. After the siding is installed, regular care is needed to help it stay strong. Siding can last for many years as long as it is installed properly and not abused in any way.
