Helical deck piers, also known as screw piles, may be what your deck, sunroom, storage spaces, or even mobile home needs. Unlike push or helical foundation piers, helical deck piers are designed to bear the weight of smaller structures attached to or annexed from the typical home. They can also be used for smaller residential structures like cottages, sheds, mobile homes, or even tiny homes. 

You can have helical deck piers installed as you build an addition to your home or yard, or to correct and repair a framework you’re having problems with. Installation typically takes a day and can be done year-round. With helical deck piers, you can strengthen any of these structures around your home:

  • Decks
  • Sunrooms
  • Porches
  • Pavilions
  • Sheds
  • Storage buildings
  • Cottages
  • Mobile homes
  • Elevated walkways

How to Install Helical Deck Piers

Traditional deck foundation piers are made from wood and concrete, which will weigh down or even crack over time. Helical deck piers are shaped like a spiral and will screw into the ground until it can reach load-bearing strata to support your outdoor structure for the long haul.

With so many online resources giving step-by-step directions for DIY installation, it may be tempting to try installing them yourself. However, hiring a professional for helical deck pier installation is vital, as the process requires heavy-duty tools, training, and licensure. At Peak Structural, we have experts on deck to make the installation process a breeze for you; here’s what to expect on installation day. 

  1. Screw Pile Location Points are Decided

A professional will spot the right areas where the helical pier shaft should be installed and determine if the area needs any pre-drilling. Pre-drilling is needed to prep the ground for the helical pier installation if the ground is made of rock or particularly rocky. 

The advantage of helical deck piers is that if the pile is screwed in at a wrong angle or hits rock, installers can simply remove the pile and try again. 

  1. Helical Piers are Driven into Soil

Using a small-scale torque drill, our foundation technicians can screw the steel helical pier into the ground until it reaches the resistance of load-bearing bedrock or soil strata. Now intertwined with the ground itself, your deck or exterior structure is supported by a foundation that won’t crack beneath itself. 

  1. Brackets are attached to your structure

Now, the legs of your structure are attached to brackets atop the helical deck pile. Once secured, your deck, sunroom, shed, or other structure is good to go.

Why Our Helical Piers are a Better Solution

  • Helical piers are a permanent support system for your exterior structures. Thanks to their unique and sturdy design, plus a galvanized steel shaft, helical piers are unaffected by soil issues or rust. They’ll provide solid protection for years. 
  • Our piers can restore the value of your home by returning your damaged deck to its original position. Helical piers also restore the curb appeal of your home, potentially raising the value even higher. 
  • Installation is mess-free and nearly invisible after completion. Our team can install the piers with minimal disruption to your landscaping, with the potential to complete the job in one day. 

Signs Your Home Needs Helical Deck Piers


Settlement of any kind indicates that you need helical piers right away. If you’ve noticed that some, or all, of your deck or lightweight structure appears to be sinking into the soil around your home, our piers can lift its foundation back into its original position.

Stair Step Sinking

Stair step sinking refers to when the stairs or ramp on your lightweight structure is sinking or uneven. Just like how settlement can affect the rest of your outdoor structures, it can plague your steps too. This creates a major tripping hazard for children and older adults coming over to enjoy your space for entertaining.

You’re Building Something New

When you’re building out a new deck, shed, sunroom, mobile home, etc., it’s vital to get a helical deck pier expert’s opinion early on. Many lightweight foundation installations are done using the cheapest materials or installation method—however, when it starts to falter, you’ll be spending more money in the long run. Go for the highest quality foundation option now and save later.


Some homeowners might try to repair any damage brought on by foundation issues by themselves. While some projects like painting or caulking can be completed by homeowners, foundation repair is not something you should DIY, as these projects rarely address the actual problem behind foundation damage – weak soil. Helical piers and other professional foundation repair solutions are the most effective way to repair your foundation.

Foundations are only as good as the soil they rest on. If soil becomes damaged, so too does your home’s foundation. Soil can get damaged in three basic ways: too much moisture, drought and dryness, or poor compaction. While all three can arise anywhere in the United States, Colorado homeowners need to be most aware of dried out soil. When soil gets too dry, it becomes brittle, shrunken, and unable to support your foundation. Over time, your foundation will sink into the dry soil and cause foundation damage.

Helical piers require special tools and training to install. Specialized machinery is used by our team to lower the helical piers into the ground. This machinery is unavailable to the average consumer and installing helical piers deep into load-bearing strata by hand is simply unrealistic. It is always safer to let a professional handle helical deck pier installation.
