One of the biggest issues we hear from clients all over Alaska is decks on other foundation types that heave and settle with the freeze and thaw of the soil. The results can range from damaged stairs, uneven surfaces and even doors that will no longer open. Our helical piers are guaranteed not to move and instead provide a stable foundation for your decks for years to come.

Our Anchorage and Kenai Peninsula locations always keep materials in stock, which makes for quick scheduling – nearly always less than 14 days out. TMP AK can also install helical pier foundations for your new or damaged deck in any season of the year.

Our P2 deck piers start at $350 each and the heavier duty P3 deck piers are $500 each installed.

  • This price includes all mobilization, materials and installation.
  • The price does not include installations beyond the 7’ lead pile. Soils sometimes require piers to be installed deeper into competent soils and they are billed by the foot:
    • P2 extension – $30 per linear foot used
    • P3 extension – $40 per linear foot used
