Number of Piers
The single biggest cost driver. A contractor determines how many piers are needed based on the size of your foundation, the degree of settlement, and the soil conditions. Larger homes and more severe movement require more piers. Don't accept a quote that doesn't specify the number and type of piers β it's impossible to compare quotes accurately without it.
Pier Type
Concrete pressed piers are the most commonly used system in North Texas clay soil and typically the most affordable. Steel piers go deeper and are used when the clay layer is particularly thick or settlement is severe. Helical piers are screwed into the ground and used in areas with restricted access or lighter loads.
Drainage Requirements
Many Collin County foundation repairs come with a drainage recommendation β and for good reason. Moisture imbalance around the foundation is usually what caused the problem in the first place. French drains, surface drains, or soaker hose systems may be recommended alongside pier work. These add cost but address the root cause, not just the symptom.
Home Age and Access
Older homes may have HVAC lines, plumbing, or landscaping that complicates pier installation. Tight access points β like crawl spaces, finished landscaping, or pool decks β add labor time and cost. A contractor should flag any access issues before work begins.
Getting 2β3 written quotes is standard practice for any foundation repair job. When comparing, make sure every quote specifies: pier type and number, whether drainage work is included or separate, permit fee (included or extra), warranty terms (lifetime transferable is the standard), and timeline and access plan.
A quote that's significantly lower than others may be using fewer piers than the job requires, a lower-grade pier system, or skipping drainage work that will let the problem recur. Ask every contractor to explain their pier count and why.
