Minimal Maintenance

Wipe it down, and you’re done. Our finishes are long-lasting and chip-resistant, so you don’t have to worry about touch-ups or seasonal upkeep.

Vertical Picket

Picket railings are among the most popular design for outdoor railings. Easy maintenance and a variety of options for color, picket size, and style this option is cost effective and one that we install often. Welded picket systems provide excellent structural integrity and stand up to our NW weather.

Glass

Glass railing systems are the best of both worlds. Welded aluminum frames with structural integrity surrounding glass providing clear, unobstructed views. In the NW we treasure our outdoor spaces and being able to see them clearly from any vantage point is always the goal.

We have many options; from incorporating decorative top rails to going totally glass with some of our innovative modern options. We have something to fit your application.

Mixed

Mixed railing systems are a very popular application on projects that feature the use of two or more styles or railing to enhance the look of your home. Why go with just one railing style? Combine two railing styles to bring your vision to life. We can create a seamless transition between the different styles to create a unique, yet uniform design.

    NNL Railing was detailed and professional throughout out the “seamless process” which included a fantastic referral for some deck repair work that needed to be done prior to the installation of our beautiful new deck railing. All of our questions or concerns during the process were all handled in a timely manner. My wife and I are very particular about how our home looks and functions which is why we chose NNL Railing. As a 38 year Professional Realtor I can say with confidence that our new deck railing added to the current value and future marketability of our home. Referring them to friends, family, and my valued clients will be an easy choice to make in the future.

  • Just want to say what a great experience it has been working with you. The railing is perfect thanks to your suggestions. The estimate was well detailed, the product is so high quality, and the installation was smooth and fast. Thank you so much for all of your help and your lovely professionalism. Now I’m hunting for more places I can have railings!  Well, there aren’t many opportunities in my little place, but I will happily refer anyone I know to you and will call on you again if I do ever need more railings. Stay safe, stay well, and have peace.
