Power Post and Lally Column Installations

Restore Structural Support and Eliminate Sagging Floors

When basement support columns rust, shift, or fail, the structure above them is directly affected. Sagging floors, uneven door frames, and compromised load‑bearing points are all signs that your home’s support system needs attention. At Arta Foundation Repairs, we replace failing lally columns and install permanent steel power posts to restore strength, stability, and long‑term structural integrity.

Our team understands the unique challenges faced by homeowners throughout New Hampshire, Vermont, and Maine, where aging homes, moisture exposure, and settling soils can weaken support columns over time.

Protecting Your Home From Structural Damage

Failing support columns can lead to serious problems if left unaddressed. A properly installed power post or lally column provides essential reinforcement to keep your home safe and stable.

You may need our services if you notice:

• Sagging or uneven floors
• Doors or windows sticking or misaligned
• Visible rust or deterioration on existing columns
• Cracks forming above doorways or in drywall
• Bouncy or soft spots in flooring
• Temporary jack posts that were never replaced with permanent supports

Structural issues rarely improve on their own. Professional column replacement prevents further damage and protects your home’s long‑term value.
