Winter in New England can be hard on commercial buildings. Freezing temperatures, snow, ice, wind-driven rain, repeated freeze-thaw cycles, and prolonged moisture exposure can turn small exterior deficiencies into costly building-envelope problems.

For property managers, facility directors, and commercial property owners, preparing before winter is not simply about clearing snow and checking the heating system. The building envelope—including masonry, concrete, EIFS, stucco, siding, expansion joints, waterproofing systems, and other exterior components—plays a critical role in protecting the property from water intrusion and winter-related deterioration.

A proactive commercial building winterization inspection can identify vulnerable areas before they become emergency repairs.

For New England commercial properties, ESI Waterproofing & Masonry Restoration, Inc. provides comprehensive building-envelope and exterior restoration services designed to help protect commercial, institutional, municipal, condominium, and historic properties throughout Massachusetts and New England.

Why New England Winters Are So Hard on Commercial Buildings

New England buildings experience a combination of environmental conditions that can accelerate exterior deterioration.

Winter exposure may include:

Freezing and thawing temperatures
Snow accumulation and melting
Ice dams and ice buildup
Wind-driven rain
Heavy precipitation
Moisture entering cracks and joints
Deicing salts and chemicals
Thermal expansion and contraction
Freeze-thaw deterioration of masonry and concrete
Increased moisture movement through exterior walls

Water is particularly concerning. When moisture enters cracks, joints, porous masonry, deteriorated concrete, or compromised exterior wall systems and subsequently freezes, the expansion of that water can place additional stress on building materials.

Over multiple winter seasons, these small vulnerabilities can contribute to cracking, spalling, efflorescence, corrosion, masonry displacement, deteriorated sealants, and interior water intrusion.

The best time to address these problems is before winter weather makes them more difficult and expensive to repair.

1. Schedule a Commercial Building Envelope Inspection

A professional exterior inspection should be the starting point for winter preparation.

Property managers and facility directors should evaluate the condition of:

Brick and masonry walls
Concrete surfaces
Parapets and coping
Exterior sealants and joints
Expansion joints
Window and door perimeters
Flashing
EIFS systems
Stucco
PVC and clapboard siding
Foundation walls
Below-grade waterproofing
Parking structures
Balconies and elevated slabs
Loading docks
Mechanical penetrations
Historic masonry details

The goal is to identify where water can enter the building envelope and where winter weather could accelerate existing deterioration.

ESI Waterproofing & Masonry Restoration specializes in evaluating and restoring commercial building exteriors, helping property owners prioritize repairs based on building condition, water exposure, and long-term asset protection.

2. Inspect Masonry for Cracks, Spalling and Deterioration

Masonry is one of the most common areas affected by New England’s freeze-thaw cycles.

Before winter, look for:

Cracked bricks or mortar joints
Spalled brick
Loose masonry
Deteriorated mortar
Efflorescence
Water staining
Displaced masonry
Deteriorated lintels
Failed flashing
Damaged coping
Open or deteriorated joints

Even a relatively small crack can become a pathway for water.

When water enters masonry and freezes, expansion can contribute to additional cracking and deterioration. Addressing masonry defects before temperatures consistently fall below freezing can help prevent minor conditions from becoming larger restoration projects.

ESI provides commercial masonry restoration services including masonry repair, repointing, restoration, and related building-envelope repairs.

For older or historically significant buildings, restoration should also consider the original masonry materials, construction methods, architectural details, and preservation requirements.

3. Check Concrete for Spalling and Cracking

Concrete is also vulnerable to New England winter conditions.

Inspect:

Parking garages
Parking decks
Foundation walls
Concrete slabs
Balconies
Loading docks
Walkways
Stairs
Retaining walls
Exterior structural elements

Pay particular attention to spalling concrete, exposed reinforcing steel, cracks, delamination, and areas showing evidence of water infiltration.

Deicing salts can create additional challenges for concrete structures by contributing to corrosion of embedded reinforcing steel. Once deterioration begins, freeze-thaw exposure can accelerate the damage.

ESI provides commercial concrete restoration and specialty coating services to address deteriorated concrete and help extend the service life of commercial structures.

4. Evaluate Waterproofing Before the First Major Freeze

A waterproofing system is only effective when the building envelope is properly maintained.

Before winter, inspect areas such as:

Foundation walls
Below-grade walls
Plaza decks
Parking structures
Retaining walls
Concrete decks
Expansion joints
Masonry transitions
Window and door openings
Areas around penetrations

Signs that a commercial property may have a waterproofing problem include:

Interior water stains
Damp walls
Musty odors
Efflorescence
Peeling coatings
Deteriorated concrete
Repeated leaks
Cracking
Moisture around windows or doors

If a building has experienced recurring water intrusion, simply repairing the interior damage may not address the source.

The source of the water should be investigated at the building envelope.

ESI’s commercial waterproofing services are designed to address water-intrusion vulnerabilities and help property owners protect their buildings from moisture-related deterioration.

5. Inspect Expansion Joints and Sealants

Expansion joints are especially important on commercial buildings because they accommodate movement caused by temperature changes and building movement.

As temperatures fluctuate, materials expand and contract. Deteriorated joint sealants can lose their ability to accommodate that movement, leaving openings where water can enter.

Before winter, inspect:

Expansion joints
Control joints
Construction joints
Window perimeter sealants
Door perimeter sealants
Masonry joints
Concrete-to-masonry transitions
Roof-to-wall transitions

Look for:

Cracking
Shrinkage
Separation
Hardening
Missing sealant
Adhesion failure
Gaps between materials

Replacing failed sealants before winter can be an important component of a broader waterproofing and building-envelope maintenance strategy.

6. Examine EIFS and Stucco Systems

Commercial properties with EIFS or stucco should receive particular attention before the winter season.

Inspect for:

Cracks
Impact damage
Deteriorated finish coatings
Open joints
Failed sealants
Discoloration
Bulging
Soft or damaged areas
Evidence of water intrusion
Deterioration around windows and penetrations

A visible crack or failed sealant joint may indicate a localized problem, but water can travel behind exterior finishes and create concealed deterioration.

ESI specializes in EIFS repair and new installations as well as stucco repair, helping commercial property owners address exterior wall-system problems before they develop into more extensive repairs.

7. Check PVC and Clapboard Siding

Siding systems are another important component of winter weather protection.

Inspect commercial siding for:

Loose or damaged panels
Cracked components
Failed trim
Open joints
Deteriorated flashing
Water staining
Improperly sealed penetrations
Damage around windows and doors

For older New England properties, siding replacement may also need to balance modern performance requirements with the architectural character of the building.

ESI provides PVC and clapboard siding replacement, making it possible to address deteriorated exterior siding while improving the building’s overall weather resistance and appearance.

8. Pay Special Attention to Historic Commercial Properties

New England has an extensive inventory of historic commercial, institutional, municipal, and residential properties.

Historic buildings require a different approach to winter preparation.

Repairs should consider:

Original masonry
Historic mortar
Architectural details
Existing building materials
Traditional construction methods
Compatibility of replacement materials
Historic preservation requirements
Water-management strategies

Replacing historic materials with incompatible modern materials can sometimes create additional problems.

ESI provides historic restoration services with an emphasis on preserving architectural character while addressing the building-envelope conditions responsible for water infiltration and deterioration.

9. Verify Flashing, Copings and Water-Shedding Details

Flashing is an important component of commercial building water management.

Massachusetts building-code provisions address weather protection and moisture management at exterior walls. The state’s building code includes requirements addressing flashing and moisture protection, including provisions associated with masonry, copings, sills, and locations where moisture could enter wall assemblies.

Property managers should have vulnerable areas evaluated, including:

Copings
Parapets
Window sills
Lintels
Roof-to-wall transitions
Masonry penetrations
Wall openings
Shelf angles
Foundation transitions

A building can have a relatively sound exterior finish while still experiencing water intrusion because of concealed or deteriorated flashing.

10. Understand Massachusetts Building-Code Requirements

Commercial property owners planning exterior repairs in Massachusetts should consider the applicable provisions of the Massachusetts State Building Code, 780 CMR, along with applicable local requirements, project-specific regulations, and permitting requirements.

Massachusetts also has multiple building-energy-code pathways. The current framework includes the Base Code as well as optional Stretch and Specialized Code pathways adopted by participating municipalities.

Important: Building-code requirements can vary depending on the scope of work, building classification, municipality, historic status, and applicable code pathway.

Property owners should verify project-specific requirements with the appropriate building official, architect, engineer, or code professional.

11. Create a Winter Repair Priority List

Not every exterior deficiency needs to be addressed simultaneously.

For commercial property managers, it can be helpful to categorize conditions into three levels:

Priority 1: Immediate Water-Intrusion Risks

Address conditions such as:

Active leaks
Open wall penetrations
Major masonry cracks
Failed expansion joints
Severe spalling
Loose masonry
Failed waterproofing
Significant parapet deterioration

Priority 2: Conditions That Could Worsen During Winter

Examples include:

Minor masonry cracking
Deteriorated mortar
Failed sealants
Early concrete deterioration
Damaged siding
EIFS or stucco cracks
Localized coating failure

Priority 3: Long-Term Capital Improvements

These may include:

Full facade restoration
Large-scale masonry restoration
Building-wide waterproofing
EIFS replacement
Siding replacement
Historic restoration
Concrete restoration
Specialty protective coatings

This approach can help property managers coordinate immediate repairs while developing a longer-term capital plan.

12. Don’t Wait Until the First Winter Leak

One of the biggest mistakes commercial property owners can make is waiting until winter weather exposes the problem.

Once freezing temperatures, snow and ice arrive, exterior restoration work can become more challenging depending on the materials, scope, weather conditions, and required installation temperatures.

A proactive fall inspection can give property managers time to:

Identify vulnerable areas.
Document existing conditions.
Prioritize repairs.
Obtain estimates.
Coordinate access.
Schedule qualified contractors.
Complete critical waterproofing and restoration work before severe winter conditions arrive.

Preventive maintenance is generally easier to plan than emergency building-envelope repairs.
