DIY Options for Stairs Handrails

Building Codes

• You'll need to check the local building codes and subdivision restrictions before you start your project. Many areas have height requirements for handrails. There are also width restrictions on the spacing allowed between two balusters (spindles) and between the bottom railings and stairs. This code is designed to protect children from getting their bodies caught between two components. Many jurisdictions may require plans in order to get a building construction permit.

Handrail Components

• Measure the total rise, run and length of the staircase. There are many online sources like Carpentry Pro Framer that will show you have to calculate these measurements. Once you have the dimensions for your stairs handrails, purchase the materials you'll need to complete the project either separately or go ahead and buy a handrail kit. The components you'll need are top rails, bottom rails and balusters or spindles. Stairs handrails can be made from an array of materials, including wood, vinyl, iron or metal. Wood is the most popular material for both interior and exterior handrails.

  The variety of woods available for interior staircase handrails includes pine, oak, cherry and mahogany. Use cedar or pressure-treated lumber on the outside. Some people mix different materials to create one-of-a-kind designs. Metal handrail components are available in stainless-steel and polished brass.

Installation Tips

• Stairs handrails are usually installed at a height of 34 to 38 inches. Measure the distance from the surface of the landing, or from the front edge of the final tread, to the top of the handrail. The two most common options for installing stair handrails are securing the handrails to the wall or on posts.

  Wall installations require metal brackets to be secured to the wall. The bracket fasteners must penetrate the wall material and enter the studs. Most regulations require brackets to be installed at least every 48 inches. Use masonry screws when attaching brackets to masonry walls. Subtract the length of the bracket and the thickness of the handrail when computing the finish height of the handrail.

  Another technique is to install handrails to newel posts. Install the posts on the top landing and at the bottom of the staircase.

  Metal handrails are often installed using the methods outlined above and also by mounting metal flanges on treads, landings or floors. These brackets can also be fastened to concrete or on other solid surfaces.

  Drill pilot holes for fasteners when using wood. The pilot holes will greatly reduce the chance of splitting boards, especially when inserting fasteners near the edge of planks.
