Foundation Forecast 2026: What New England Homeowners Should Prepare For (Part 5)

Foundation Forecast 2026

Welcome to NEFCR’s Winter Foundation Readiness Series — a 5-week guide designed to help New England homeowners understand, prepare for, and protect against the structural challenges winter brings. Each Wednesday in December, we’re diving into a new topic that affects foundations during the coldest months of the year. Follow along as we break down the causes, warning signs, and solutions that keep your home safe through winter.

This is part 5, the final article for this series.

What 2026 Winter Conditions May Bring

Early weather models and recent climate patterns point to several trends homeowners should be prepared for as 2026 approaches. New England winters have become increasingly unpredictable, which means foundations will face more stress, more moisture pressure, and more freeze-related movement.

Below is NEFCR’s expert outlook on what homeowners can expect — and why being proactive now can prevent costly repairs later.

Earlier and More Aggressive Freeze Cycles

Winter 2026 is projected to begin freezing earlier than usual, with deeper frost penetration into the ground. When frost sets in early:

• moisture in the soil freezes and expands sooner

• frost heave forces become stronger

• footings and slab foundations experience more upward and lateral pressure

Homes with shallow footings, poor drainage, or older construction may see movement or cracking before January even arrives.

Heavier Snow Loads and More Meltwater Pressure

Forecasts indicate above-average snowfall followed by intermittent warm spells. This “freeze–melt–freeze” pattern creates:

• increased hydrostatic pressure on foundation walls

• more water pooling around the home’s perimeter

• higher risk of leaks in older or weakened waterproofing systems

• sump pump overuse and mid-winter failures

Basements that were dry for years may experience new seepage under these conditions.

Increased Demand for Structural Stabilization

Many 2025 inspections revealed aging or weakened support systems in older New England homes. With heavier winter loads predicted, NEFCR anticipates increased structural issues such as:

• bowing or bulging basement walls

• settling or shifting beams

• lally column corrosion or collapse

• sagging floors due to inadequate support post load

Homes built before 1970 — especially those with fieldstone or block foundations — are expected to experience a rise in structural symptoms.

Higher Need for Mid-Winter Inspections

The 2025 season showed that many homeowners waited until spring to address issues that had been visible since January. Early detection is key.

February and March will likely be the most volatile months, with:

• rapid freeze–thaw cycling

• foundation movement

• sump pump strain

• widening cracks

• moisture intrusion through cold joints and porous areas

A mid-winter foundation check can prevent high-cost emergency repairs in April and May.

How to Prepare for Early 2026

A strong winter foundation strategy focuses on prevention, monitoring, and early intervention. NEFCR recommends:

1. Schedule a winter foundation check

Identify early movement, new cracks, or signs of frost heave before they worsen.

2. Test and monitor your sump pump system

This includes primary pumps, backup pumps, and discharge lines, all of which are more likely to fail during freeze–thaw cycles.

3. Inspect all known cracks monthly

Even small cracks can widen dramatically in deep winter. Catching changes early makes repair easier and less expensive.

4. Evaluate structural supports

Look for sagging floors, rusting lally columns, shifting beams, and wall bowing — especially in older homes.

5. Clear snow from foundation edges

Removing accumulated snow reduces meltwater volume and pressure against basement walls.

6. Stay alert for moisture changes

Dampness, water staining, or musty odors can indicate rising water pressure or a failing waterproofing system.

Closing the Series

Thank you for following NEFCR’s Winter Foundation Readiness Series. Our goal is to give homeowners the knowledge and confidence to protect one of their most important investments — their home’s foundation.

Understanding how winter affects soil, concrete, moisture, and structural components is the first step toward preventing small issues from becoming serious problems.
