Why Seattle Picks Us
Custom Exterior Railings in Seattle Designed for Your Home and Business
Seattle decks and balconies take a beating from the weather, and they often frame a view worth protecting, so the railing has to do two jobs at once: stand up to the wet and stay out of the way of the outlook. A railing that suits a modern rooftop deck in Ballard is rarely right for a hillside deck in West Seattle, which is why we design and fabricate every exterior railing to the specific property.
Most companies that come up in a search for exterior railings in Seattle are reselling stock systems or subcontracting the work. We do it differently. Design, fabrication, and installation all run through our own team out of our Kent shop, which gives us tighter quality control on the finishes that matter most outdoors and a more precise fit on a deck that is rarely a simple rectangle.
Whether you want modern metal, the openness of glass, the clean horizontal line of cable, or ornamental detail for a classic home, we build exterior railing systems made for your space and finished to last in the Seattle climate. The result is a railing that looks intentional, fits properly, and holds up season after season.
What We Build
Exterior Railing Types for Every Seattle Property
We build several types of exterior railing, in metal, glass, and cable, each finished for the weather and available in styles from clean and modern to detailed and decorative. Here is how each tends to land on a Seattle property.
Metal Railings
Metal is our most popular exterior railing, and for Seattle decks and stairs we work in steel, aluminum, and wrought iron. Powder-coated steel is strong and looks sharp in matte black, a favorite here, while aluminum will not rust, which makes it a smart pick for a deck exposed to constant rain. Every metal railing is finished through a multi-step process so it stands up to the wet.
Glass Railings
Glass exterior railings keep a Seattle view wide open, which is the whole point on a deck looking toward the Sound, the lake, or the mountains. We install framed, frameless, and semi-frameless systems in tempered safety glass. Instead of slicing the outlook into vertical strips with pickets, glass holds the panorama intact while still doing the work a railing has to do.
Cable Railings
Cable railings hit the sweet spot between open and structured. Thin stainless cables run horizontally between metal posts so the railing nearly disappears against a view, which makes them a favorite on Seattle rooftop decks and hillside homes. Near saltwater we step up to 316-grade stainless so the marine air has nothing to corrode.
Local Experts
Exterior Railings Across Every Seattle Neighborhood
We have installed exterior railings across Seattle, and the recommendation shifts with the neighborhood and the terrain. Each part of the city has its own architecture and its own exposure, and we adjust the material and finish to suit.
On the hillsides of Queen Anne, Magnolia, and West Seattle, the work is mostly view-deck railings where glass or cable preserves the outlook. In Ballard, Fremont, and Capitol Hill, rooftop decks and modern townhomes drive the demand, usually with matte-black metal or cable. In the older neighborhoods like Mount Baker and Madison Park, the classic homes lean toward ornamental metal that matches their character.
Closer to the water, in Alki and the lakeside neighborhoods, we step up to 316-grade stainless for the marine air. Across the denser parts of the city, new mixed-use and multi-family buildings bring balcony railings built to code. Wherever the property is, we match the material, finish, and style to the home and its exposure.

Seattle Specific
Why Exterior Railings in Seattle Are Different
Seattle’s wet climate is the single biggest factor in an exterior railing. Months of rain and damp will find any weak point in a finish, so the material and the coating have to be chosen for it. We use powder-coated steel finished over a primer, aluminum where rust is a concern, and marine-grade stainless near the water, then seal every penetration so moisture cannot work into the connections and loosen them over the years.
The terrain is the other half. Seattle’s hills produce decks that step down slopes, staircases that switch back, and rooftop decks that wrap around odd parapets, none of which a stock railing kit fits cleanly. Building each railing custom lets us match the exact angle, rise, and layout of the deck or stair, and on an older home, match or complement the existing detailing rather than forcing a generic system onto it.
Styles
Exterior Railing Styles
Whether you want sleek and minimal or warm and detailed railings, we have the skills and materials to build it. Here are the railing types Seattle homeowners request most often.
Modern Railings
A modern exterior railing in Seattle means clean lines, minimal detailing, and an architectural feel that holds up to the weather. That comes through as slim matte-black metal, glass that keeps a view open, or cable that adds almost no visual weight. The city’s newer homes and rooftop decks lean toward this look, and we design and build the version that fits your space, whether that is flat-bar steel, frameless glass, or a clean cable run.
Ornamental Railings
Ornamental railings bring detail and character to an entry, porch, or balcony. Scrollwork, twists, and custom patterns turn a railing into part of the home’s design, which suits Seattle’s many classic homes in neighborhoods like Queen Anne and Madison Park. Finished properly for the outdoors, ornamental iron holds up well here, and our fabricators can reproduce an existing design or create something new that still feels authentic to the home.

Posted on Google Kristina G.Trustindex verifies that the original source of the review is Google. We're so thrilled with our new stair railings! Custom Railings WA and Mike's team did a high quality job from start to finish. We got the black powder coat finish with hemlock handrail in natural stain, which looks so elegant (see attached photos). The powder coat finish is really attractive, and we like that it's durable and not easily scratched. We were a little nervous that the wood color/characteristics on the top rail might turn out to be inconsistent across such a long run of railing, but the hand rails on all of the railings match beautifully. Thank you, Mike and team for taking such great care of us! Our new stairs are the perfect touch for our new farmhouse.Posted on Google Adele FesanTrustindex verifies that the original source of the review is Google. We used this company for the second time, and this was our first time ordering railing for an outdoor deck. The service was absolutely outstanding from start to finish. Communication was excellent, the team was easy to work with, and everything was completed exactly on schedule. The installation crew was highly professional, respectful, and left the area clean after completing the job. It was truly a pleasure working with a company that operates with such care and professionalism. The quality of the railing is top-notch — a very high-end product that exceeded our expectations. We would highly recommend this company and will definitely use them again in the future.Posted on Google Leyla HasanovaTrustindex verifies that the original source of the review is Google. We ordered glass railings for our parents’ home in Seattle. We were choosing between two options, glass or modern metal railings, and in the end we decided to go with glass. We’re extremely happy with that choice. The team helped us understand the differences, guided us through the design, and completed the installation on time. The railings look amazing. Great experience overall!Posted on Google Zamina BabayevaTrustindex verifies that the original source of the review is Google. From the first day, they were professional and easy to work with. Mike always replied quickly, and the team made sure every detail was just how I wanted. In the end, we got beautiful glass railings that fit perfectly with our modern home in Bellevue. Thank you, Custom Railings WA, for making the whole process smooth and enjoyable!Posted on Google J BTrustindex verifies that the original source of the review is Google. I had such a good experience getting outdoor railings for my front concrete steps and for my stone steps in the back garden. I had put off doing this for so long and thought that railings might detract from the aesthetic look of my yard, but I was so wrong. I absolutely love my new railings, and loved working with all the guys who came out - to measure, to bend the metal and dig post holes, and finally to install the finished railings. Thank you!Posted on Google Jill SprattTrustindex verifies that the original source of the review is Google. We had a wonderful experience with Mike and his crew at Custom Railings WA. From design planning to installation they were knowledgeable, patient, helpful and professional.Posted on Google K CarrollTrustindex verifies that the original source of the review is Google.

We have beautiful new railings thanks to Custom Railings. Good communication, beautiful product, and they made sure everything was clean before they left.

They replaced our outdated railing with a new custom designed railing that fit our dreams and our budget. Communication was always clear and timely. They even worked around the chaotic schedule of other contractors working on our bigger remodeling project that impacted when the railing could be installed. Very Happy with our railing.

Frequently Asked Questions
How do exterior railings hold up to Seattle’s rain over time?
CustomRailingsWA2026-06-29T09:32:51-07:00Well, when they are built for it. The key is the material and the finish: a multi-step coating over steel, naturally rust-free aluminum, marine-grade stainless near the water, and sealed connections so moisture cannot collect at the joints. A railing built this way handles years of Seattle wet without the staining or loosening that a poorly finished system shows after a few seasons.
Do you install exterior railings outside of Seattle too?
CustomRailingsWA2026-06-29T09:32:13-07:00Yes. We install across Seattle and throughout the greater Puget Sound region, with all fabrication done from our Kent shop. That covers decks, balconies, porches, and exterior stairs on homes and commercial buildings alike.
Can you combine materials like wood and metal on an exterior railing?
CustomRailingsWA2026-06-29T09:31:34-07:00Yes, and it is a common request in Seattle. A wood top rail over steel pickets, cable, or glass blends warmth with a weather-tough frame, and it ties a railing into cedar decking nicely. Because we fabricate in-house, combining materials cleanly in one exterior railing is straightforward, and we finish each material for the outdoors.
What is the best exterior railing material for Seattle’s climate?
CustomRailingsWA2026-06-29T09:30:55-07:00Powder-coated steel is the most versatile, since it is strong and, finished over a primer, handles the wet well in nearly any color. Aluminum is a smart choice where rust is a concern because it will not corrode, and for decks near saltwater we use marine-grade stainless. Tempered glass and stainless cable both perform well outdoors here too. We help you weigh the options for your specific deck and its exposure.
