"Not good! Initial appt went well. Lots of ideas and suggestions by the two reps. They rendered artwork on the spot to ensure that their product would match our existing rails. But it went down hill from there. They did warn us that products may be difficult to get in the current climate. We anticipated that. But there was no follow-thru. Weeks went by with no word. We had to frequently call the office with no response. When we did hear, we were told it would be more weeks before installation. We initiated all of the communication., Nor /Cal did not call us to keep us apprised of the progress of the project. When the product was finally installed it looked good and did match the existing iron work. But the progress of the process was horrible. It took over two months from inception to completion for a very small job. If you are not in a hurry, I guess it would be worth it."

"Moses and his crew came out and replaced some porch railings that had rotted away. The work was beautifully done and the railings are very sturdy. I am very happy with the work. Definitely worth the price."

"We found McCormick home builders through Angie’s list. They were not one of our original contacts, but they contacted us and came out to give us a quote. Matteo was extremely helpful, informative, honest, and gave us reasonable realistic prices, and did not try to inflate the prices or pressure us in anyway. We felt very comfortable with him immediately. We felt like he was a member of the family that we could just talk to and ask questions he was very personable. He gave us his contact number in case we had other questions and he was always available when we needed him for any type of questions or concerns. Mateo‘s team did a beautiful job. They were fast. They were efficient. They cleaned up beautifully. They did a wonderful job. They were very considerate of our time our needs and our neighbors. They were an absolute pleasure to work with. I would highly recommend Matteo from McCormick home builders for any home building projects, and we will be calling him again in the future!"

"It was a pleasure to work with Ariel and GMD Builder. They responded to our request and scheduled a site visit promptly. We needed a quote and recommendations for installing a metal railing for a ~60' long curved staircase from our back door to the garden and pool area above. GMD gave us several options for both function and aesthetics. They were great in listening to our thoughts and coming to a good solution. They were flexible, reliable, and honest. We would use them again."

Install Stair Railings FAQs, answered by experts

Regular sealing or staining, non-slip treads, and correcting water pooling help avoid damage. Households prone to extreme weather should prioritize these measures.

Most building codes require that railing spindles (also known as balusters) on decks or stairs be spaced no more than four inches apart. This safety standard is often called the '4-inch sphere rule,' which means a sphere with a 4-inch diameter should not be able to pass through the opening between balusters. This rule is in place to prevent small children and pets from slipping through the railing. For the same reason, the space between the bottom rail and the deck or floor surface should also be no more than four inches. As a general guideline, professionals often install three balusters per foot of railing. However, since specific requirements can vary by location, it is essential to check your local building codes to ensure compliance before starting your project.

The four-inch ball rule, also known as the four-inch sphere rule, is a safety requirement for railings on structures like decks and stairways. It states that a four-inch sphere should not be able to pass through any gap in the railing system. This applies to the spaces between balusters or spindles, as well as the gap between the bottom rail and the deck surface. The purpose of this rule is to prevent small children and pets from accidentally squeezing or slipping through the railing.

A properly installed spindle should last decades or more, depending on the material, environmental conditions, and wear-and-tear from teething puppies or kids clunking bags up and down the stairs. Wood spindles may need more frequent maintenance and eventual replacement compared to metal or composite alternatives. Regular inspection and maintenance will help maximize their lifespan.

Building a new staircase can take anywhere from a few days to a few weeks, depending on the complexity of the design, materials, and whether an old one needs to be demolished. Straight staircases are quicker to build than curved or spiral staircases, which require more intricate design and precise measurements.
