"This review is long overdue! We had the pleasure of working with Robert on renovating our new house from top to bottom almost a year ago, and we are still thrilled with the results. Their professionalism, attention to detail, and commitment to quality has created a deep trust in Robert. He is top of our list and we have recommended him and his team to all our family and friends. We knew he would be a good fit from the initial consultation. Roberto managed everything with care and great attention to detail. Robert and his team executed our vision so well and everyone who has been over have showered us with compliments at how good everything looks. Throughout the renovation Roberto maintained excellent communication, keeping us updated at every stage. They were always punctual, courteous, and willing to answer any questions we had. His team was respectful of our home and ensured that the worksite was clean and organized at the end of each day. The quality of workmanship has proven to be outstanding and the custom work will last us for years to come. Another impressive aspect of working with Roberto and team was their ability to stay on schedule and within budget. They provided a clear timeline at the beginning of the project and adhered to it, completing the work on time without any unexpected costs. Even after the project was completed, Roberto continued to provide exceptional customer service and followed up to ensure we were satisfied with the work. We highly recommend Roberto to anyone looking for a reliable, skilled, and professional contractor. Our new house is beautiful and suits us perfectly thanks to Roberto and his team!"

"Let me start by saying this the third bathroom John has gutted and recreated for us. I found John on Angie’s list about 6 years ago to renovate a bathroom on our first floor. He was amazing! Turning a tiny serviceable bathroom to a beautiful shower space. In May of 2025 I dug out John number to get him to do his magic again, this time to renovate 2 more bathrooms. One is a giant master bath, the other a small guest bathroom, both with the original decor of 1993! I love John’s process. He comes and listens to your visions then adds his own expert suggestions and provides a quote and a shopping list. When you have all the items in home you let him know and he sets the date for renovation and gives you the timetable which he adheres to. John is exact and meticulous, and works through until finished. He is timely and reliable and a charming presence at 7 am when he religiously starts his days. John was assisted by Mike who was also a meticulous craftsman and in addition a great painter. The end result is nothing short of gorgeous. Our master bath was transformed to the modern era and John’s attention to detail and artful eye creates a masterpiece."

Install Stair Railings questions, answered by experts

Many contractors offer staircase services, but you can also find stair companies that are dedicated exclusively to staircase installation and makeovers. If you’re planning a more elaborate design, search for reputable stair building contractors who will provide estimates, detailed project drawings, and superior finished products. You might pay a little more for this specialized labor, but it’s often worth the added investment.

Spiral staircases can be installed outdoors using weather-resistant materials, such as galvanized steel, aluminum, or treated wood. Outdoor installations may require additional coatings or finishes to prevent rust and decay, and costs may be higher due to site prep and exposure to the elements. Outdoor staircases must also comply with local building codes, which can affect the dimensions, handrail requirements, and load capacities to guarantee safety in all weather conditions.

In some cases, stairs without carpet are actually slipperier than carpeted stairs, but if the carpet is brand new, dirty, or just slick, it may seem like your stairs are the most slippery ones in existence. Fortunately, traction treads can be added over most stair surface materials, increasing the traction you’re able to get and reducing the risk of slipping.

The best finish for wood stairs is polyurethane, specifically a high-durability option like oil-based or water-based polyurethane. Oil-based polyurethane provides a rich, amber tone that enhances the wood’s natural grain and is highly durable, making it ideal for areas with heavy foot traffic. Water-based polyurethane, while slightly less durable, dries faster, has less odor, and maintains the wood’s natural color without yellowing over time.

Building codes for spiral staircases will vary by your location. Most local codes will specify minimum tread width, riser height, handrail requirements, and headroom. These standards help ensure safety and accessibility for all users. Always check local codes before you begin the installation to ensure compliance and avoid costly modifications or fines.

By submitting this question, I acknowledge and agree that Angi may publicly display my name, city, state, and question on the website for professionals and others to see.
