Helical pile installers in Massachusetts

Helical Piles in Massachusetts

Massachusetts sits on ground shaped by glaciers. The state soil, Paxton, formed in dense glacial till on drumlins, ground moraines and till plains, and the Soil Science Society of America's Massachusetts soil guide reports that it covers about 400,000 of the state's more than 5 million acres. The same guide describes a firm, brittle subsoil with dense layers that can perch seasonal water tables, plus frost action that affects building sites. Helical piers handle that variety because they are screwed in with hydraulic equipment, and the installer tracks torque as each pier advances to confirm it has reached adequate bearing below frost and below weak surface soil.

Helical pile cost in Massachusetts

We could not find a Massachusetts-based installer that publishes per-pier prices, so the figures below combine one nearby contractor with national ranges. Treat them as a starting point and get site-specific quotes.

For a whole house, Today's Homeowner puts a typical national repair at $15,000 to $30,000, at about $3,000 per pier. In Massachusetts, depth to firm till, access on tight lots and the number of piers move the total most. Run your own numbers with our helical pile cost calculator, and see the helical pier cost guide for what drives each line item.

Soils and frost depth in Massachusetts

A statewide USGS surficial geology map made with the Massachusetts Geological Survey shows how uneven the ground is. Loose surface deposits range from a few feet to more than 500 feet thick, and drill holes show compact, sandy till lying directly on bedrock across much of the state. The same map describes soft, layered silt and clay in old glacial lake beds such as the Connecticut Valley, and glaciomarine clay along the coast and in estuaries. On Cape Cod, the USGS reports glacial deposits from more than 200 to more than 600 feet thick, so piles there bear in sediment rather than rock.

The state code reflects this range. Massachusetts keeps its own presumptive bearing table, 780 CMR Table 1806.2a, which on UpCodes allows 10 tons per square foot for very dense till or hardpan but only 1 ton for soft or varved clay, and no presumptive value for organic soils like peat.

Frost depth is fixed statewide. The Massachusetts Residential Code Table R301.2 sets the frost line at 48 inches, and Section R403.1.4.1 requires piers and other permanent supports to extend below it unless another listed method applies. Helical piles usually go well past 48 inches to reach bearing, so frost rarely limits the design. Our frost heave guide explains how the shaft resists uplift.

Permits and codes in Massachusetts

The 10th edition of the Massachusetts State Building Code (780 CMR) took effect on October 11, 2024, according to the Holbrook Building Department, and the 9th edition ran alongside it only until June 30, 2025. The commercial code moved from the 2015 to the 2021 International Building Code, and the residential code (780 CMR 51.00) adopts the 2021 International Residential Code with state amendments.

• Commercial and larger work: under IBC Section 1810.4.11, as shown on UpCodes, helical piles go in to the depth and torque a registered design professional sets, without exceeding the manufacturer's rated torque. We found no Massachusetts amendment to these helical sections.
• Houses, decks and additions: building officials usually accept helical piles through an ICC-ES evaluation report under acceptance criteria AC358 or a stamped engineer's design. See our permits and codes guide.
• Permit: foundation repair, additions and most decks need a permit from your local building department.

Common projects

• Decks, porches and sunrooms that must bear below the 48-inch frost line without large excavations. See helical piles for decks.
• Coastal and flood-zone homes. The residential code's Section R322 sets the design flood elevation at base flood elevation plus 2 feet in A Zones and plus 3 feet in V Zones and Coastal A Zones, and coastal high-hazard buildings must sit on anchored pilings or columns. Flood-insured owners ordered to elevate may get up to $30,000 through FEMA's Increased Cost of Compliance coverage.
• Foundation repair for older homes with settled or frost-damaged foundations. See helical piers for foundation repair.
• Commercial work on filled land. Braintree-based Helical Drilling installed 48 helical piles rated at 30 kips each under the Faneuil Hall Marketplace pavilion in Boston, on land filled centuries ago, according to High-Profile.

How to choose an installer in Massachusetts

Start with the Massachusetts companies listed on this page, then use our guide to hiring a helical pile contractor. Ask each bidder for the product's evaluation report number, the target torque and minimum depth, and a torque log for every pile. On the coast, ask about galvanizing and experience with flood-zone pilings. Make sure every quote uses the same pier count and depth assumptions, and confirm who pulls the permit.

Massachusetts helical pile FAQs

How deep do helical piles go in Massachusetts?

At least below the 48-inch frost line in Table R301.2, and usually deeper. The final depth is wherever torque readings show the capacity the engineer specified.

Do helical piers work in glacial till?

Often, yes. Dense till can carry high loads, but it can also hold cobbles and boulders, so the installer and engineer should review boring data or local experience before work starts.

Do I need a permit for helical piers in Massachusetts?

For foundation repair, additions, new structures and most decks, yes. Your local building department issues the permit under the 10th edition of 780 CMR.
