Without question, glass railings stand out as a premier choice for those seeking a contemporary, low-upkeep option among the wide array of selections available in the current market.
The national average for installing glass railings stands at around $485 per linear foot. The actual price, however, ranges between $250 on the low end, and $765 on the higher end of the spectrum.
In this guide, we’ll go into details on how much you’ll spend to install a glass deck railing and show you how the costs come about.
Compared to other railing materials like wood or vinyl, glass railings aren’t cheap.
Installing a glass railing on a 20 linear foot deck will range between $5,000 – $15,300.
These costs are relatively high due to the cost of glass and the difficulty of working with it to install. Most are custom-made to fit.
| Minimum cost per linear foot | Maximum cost per linear foot | |
|---|---|---|
| Material cost | $100 | $500 |
| Labor | $50 | $200 |
| Supplies cost | $50 | $100 |
| Permits | $50 | $300 |
| Total cost | $250 | $1,100 |
Glass railing cost factors
The average cost to install a glass railing on your deck will fluctuate depending on some of the following factors:
- Quality of glass
- Thickness
- Railing height
- Frameless or with posts
- Shape of deck
- Gates and other hardware
- Labor costs
Quality of the glass
Like most other materials, glass is manufactured in different qualities with the higher quality glass being more expensive than regular glass. Among the best quality glasses you’ll find in the market include tempered glass and laminate glass.
Thickness of the glass
For the thickness, most glasses come in ¼” (6mm), and ⅜”(9mm) as the standard thickness for the 4 feet glass panels. The ½“(12mm), ¾” (18mm), and 1” (24mm) are considered thick glasses.
The thicker glasses are generally considered stronger and safer for most American homes. They’re, however, more expensive compared to the standard glass.
Keep in mind; your local town’s building code may have some regulations regarding the standard glass thickness to be used in your area.
The glass size (height and length)
The bigger your glass is, the more you’ll spend on it. Most manufacturers produce their standard glass to 6 feet in height. Anything larger than this may add up to $5 per linear foot to your total costs.
In terms of length, you’ll find that longer glass (more than 5 feet) is much cheaper per linear ft. However, you may have to use thicker glass which raises your expenses.
Pre-drilled Holes, notches, and edge treatments
If you require any customizations for your glass railing, your costs will significantly increase. This includes if you need pre-drilled holes on the glass, treated glass panel edges (i.e., rounded, beveled, or polished), or if you need them frosted and tinted.
If the manufacturer also has to make bracket notches on the glass, the total price may increase by more than 5%.
Shape of the deck
The shape of the deck determines the complexity of the glass railing installations. Rectangular and square decks are usually the easiest and cheapest to install (since they require straight rail installation) while the odd-shaped decks become much harder and expensive.
The more complex installing the glass railing becomes, the more labor and material will be required. All these means added costs for your project.
Glass gate and other hardware
Other factors like a glass gate, glass top or bottom rails, metal posts (whether aluminum or stainless steel), post lights, post caps, mounting hardware, among other accessories will significantly add to the total glass railing project cost.
Adding glass stairs to your railing system will also increase your costs.
Glass deck railing labor costs
The labor costs you’ll incur during this installation will largely depend on the time required to complete the job. Most contractors charge you anywhere from $50 – $250 per linear ft or between $65 – $250 per hour for the project.
For a team of two installers, you can expect them to complete the installation of 40 feet of glass railing in 2 – 5 hours depending on the complexity of the deck railing.
Glass railing material and supplies cost
For the glass rail, there are two main material options for homeowners to choose from i.e., full glass panels, or glass balusters. Your decision to go with either of these materials will be determined by the style you want for your railings.
Glass panels
If you choose to go with full glass panels, expect to spend anywhere from $50 – $600 per linear foot, or around $10 – $80 per square foot.
The glass panels are a great addition to an outdoor living setup, ensuring you get the best views from your porch. It’s, however, more expensive to install a glass panel compared to glass balusters.
Glass balusters
The other alternative is using glass balusters for your deck railings. The balusters are usually about 3 – 4 inches wide and are spaced around 3 feet apart. This ensures they can allow free flow of air through its spaces into your deck.
It’s often used alongside wood to provide that classic-contemporary feel to your home. Glass balusters are also much cheaper than glass panels.
Expect to spend anywhere from $20 to $55 per linear foot for the material. Its installation is, however, higher than that of glass panels since each baluster has to be installed separately.
The labor costs for these installations could range from $60 – $200 per hour depending on the contractor.
Additional materials and hardware
Other supplies and hardware materials you may need for the installation include:
| Extra supplies | Cost |
|---|---|
| Top rail | $10 - $50 per foot |
| Clamps | $18 - $40 each |
| Handrail bracket | $70 - $150 each |
| Posts | $200 - $700 |
| End Caps | $25 - $65 |
| Handrails | $5 - $40 per foot |
| Shoe molding | $45 - $60 per foot |
Glass railing cost by style
The style of your glass railing systems will also be crucial when estimating your final project cost. When you visit your local hardware store, you’re likely to run into these three popular glass railing styles:
Frameless glass railing system
In this glass railing type, the installer uses no posts or beams as the support system for the glass. From afar, the glass railing will have an invisible ‘frameless’ appearance.
However, it usually has a shoe base and top cap to secure the glass in position.
This style makes your deck appear more spacious and is perfect for anyone whose claustrophobic.
Point glass railing system
Point glass relining refers to a system that comes with a defined attachment or fixing point for the glass, top rail, and handrails. This could be along the side of the stairs, balcony, porch or deck.
The biggest advantage of this system is that installation is easier, and it creates a lot more space on the deck compared to when the glass is fitted to a profile.
Post glass railing system
Right from the name, post glass railings use a post, either stainless steel or wood, as the support for the glass. The posts hold the glass infill firm in position and can be easily modified to support handrails and other relevant fixings.
The price difference between these three systems is pretty similar, with the cost ranging from $150 – $900 per linear foot.
Tempered glass railing cost
If you intend to work with tempered glass, your costs will increase to around $15 – $30 per square foot. This toughened glass can be as thick as 1¼” which is miles tougher than the ¼“ thick ordinary glass.
However, before you install tempered glass, ensure you consult your contractor to find out if it’s the right move. In many cases, tempered glass is used on commercial buildings.
Other options for commercial properties and exterior applications include laminate glass and tempered laminate glass. Both of these options are much stronger than tempered glass and cost anywhere from $30 to $70+ per linear foot.
