"Gil did an amazing job of figuring out exactly what I needed, and he hired an amazing crew to get it done. This is by far the best home renovation experience I've ever had. Gil and Oliver both were very thorough in figuring out what needed to be done, and every step of the way if there was ever any ambiguity, they asked questions and came up with great solutions for everything that came up. I have never before had such a good experience with a home renovation, and I wish all contractors were as good as them. My project was fairly involved, with a complete renovation of my kitchen, dining room, and laundry room, and yet the whole process took under a month to get done, and it was done right the first time. I wholeheartedly recommend Your Home Builders. No complaints at all."

"The nicest and hardest working construction crew and company Iâ ve ever dealt with. Extremely excellent customer service. Employees showed up several minutes earlier than expected every morning. The large crew always work together along with the boss doing a lot of grunt work himself. They laughed and really seem to enjoy doing their job together as a team. We could not be happier with the driveway that we have waited for for 10 years."

Install Stair Railings questions, answered by experts

Spiral staircases can be safe for all ages if designed with features such as code-compliant handrails, non-slip treads, and proper spacing. However, narrow treads and steep angles may pose challenges and a safety hazard for young children or those with mobility issues, so consider safety upgrades or alternative designs if needed.

The general rule of thumb is that posts should be no more than 6 feet apart when calculating railing post spacing. The purpose of a deck or staircase railing system is to provide safety and support. For this support, the more posts the system has, the sturdier it’ll be. However, local municipal building codes always take precedence.

Although many types of railing can be fairly easy to install, cable and rope railing systems are probably the easiest. All you need to do is string them through and secure them. Barring those choices, panel railings that are pre-cut to the required size can also be very simple to DIY.

Space deck handrail posts four to six feet apart. If the posts are more than six feet apart, the railing will be less able to withstand lateral forces and is more susceptible to breaking. Additionally, railing posts that are more than six feet apart may not be up to code, and you may face fines and be required to reinstall the posts to bring them up to code.

The proper deck step height, also called a riser, is between four and seven inches. The tread depth should be at least 10 inches. For deck stairs, go with a rise of around seven inches with a run of 10 to 12 inches. These figures are intended to improve both safety and comfort, but fully depend on the design of the actual deck. Local building codes could also mandate slight discrepancies from the above numbers.
