Strong Foundations for Home Additions & Extensions
Expanding your home? Whether you’re adding a new room, second story, or full addition, your project deserves a foundation that’s just as solid as the original structure. At Screw Pile Installers, we specialize in helical pile foundations engineered to support home additions and extensions of every size—delivering strength, speed, and reliability across British Columbia and Alberta.
Helical piles provide a cleaner, faster, and more precise alternative to concrete footings—perfect for tie-ins to existing homes where space, soil, or access can be challenging.
Build Additions That Last a Lifetime
Adding to your home shouldn’t compromise its structural integrity. Our residential screw pile systems are engineered to work seamlessly with existing foundations, supporting everything from room extensions and sunrooms to garage additions and second-story expansions.
Each pile is installed to exact load-bearing specifications, ensuring your addition remains stable and level—no shifting, no settling, no surprises.
WHY CHOOSE US
Why Choose Helical Piles for Home Additions
Precision Installation
Our torque-monitored installation ensures every pile matches the exact load your new structure requires—ideal for connecting to existing foundations.
Minimal Site Disruption
Tight access or finished landscaping? No problem. Screw piles install cleanly without excavation, heavy equipment, or concrete trucks.
Year-Round Construction
Helical piles can be installed in any season, including winter, letting your project move forward on schedule—no weather delays.
Permanent Strength
Hot-dip galvanized steel piles are corrosion-resistant and built to last 75 + years, delivering a worry-free foundation for decades.
Perfect for Tie-In Projects
Unlike concrete, screw piles create a stable transition between new and existing structures—preventing differential settling that can cause cracks or misalignment.
Let’s Build a Strong Foundation Together
No waiting for concrete to cure, foundations are ready the same day, saving valuable build time.
We combine engineering expertise and precision installation to ensure your home addition rests on a rock-solid base that meets all local code and performance requirements.

Pile Installation
Using compact, low-impact hydraulic equipment, each pile is screwed into the ground until it reaches engineered torque resistance—verifying that it can safely support your structure.
[05]
Bracket Connection & Alignment
Adjustable brackets are attached to connect the piles directly to your structure or grade beam, forming a level, permanent base for framing.
[02]
Layout & Marking
Pile locations are marked with precision to align with load points and to avoid existing utilities, ensuring your extension integrates seamlessly with your current structure.
