For Property Managers, Facility Directors & Commercial Property Owners in Massachusetts, Rhode Island, Connecticut & New Hampshire

A commercial building’s exterior is its first line of defense against New England’s weather. Rain, snow, ice, wind, humidity, temperature fluctuations, freeze-thaw cycles, and road salt can gradually deteriorate masonry, concrete, siding, sealants, and waterproofing systems.

The problem is that many exterior building defects begin small.

A hairline masonry crack can allow moisture into a wall assembly. A deteriorated mortar joint can permit water penetration. Failed sealant around a window can allow moisture behind the exterior façade. A small area of spalled concrete can eventually expose reinforcing steel and accelerate structural deterioration.

For property managers, facility directors, and commercial owners, identifying these conditions early can make the difference between targeted maintenance and a major restoration project.

At ESI Waterproofing & Masonry Restoration Inc., we help commercial properties throughout Massachusetts, Rhode Island, Connecticut, and New Hampshire identify and address exterior building deficiencies before they develop into more extensive—and expensive—problems.

Why Exterior Building Defects Should Not Be Ignored

A building envelope is a system. Masonry, concrete, sealants, flashing, siding, windows, waterproofing membranes, and other exterior components work together to keep water out and protect the building interior.

When one component begins to fail, water can find another pathway.

Over time, moisture intrusion can contribute to:

Masonry deterioration
Mortar joint failure
Concrete spalling
Corrosion of reinforcing steel
Wood rot
Damaged insulation
Interior water damage
Mold and moisture-related problems
Deterioration of structural components
Failed finishes and coatings
Tenant complaints
Increased maintenance costs
More extensive restoration requirements

For commercial property owners, the financial impact can extend beyond the repair itself. Exterior deterioration may also affect tenant satisfaction, building operations, property value, insurance considerations, and capital-planning decisions.

The earlier a building defect is identified, the more opportunities there may be to address the underlying cause before deterioration spreads.

10 Exterior Building Defects Property Managers Should Watch For

1. Cracked or Deteriorating Masonry

Masonry is extremely durable, but it is not maintenance-free.

Cracks in brick, block, stone, or mortar can develop because of weather exposure, building movement, settlement, thermal expansion and contraction, moisture intrusion, or deterioration of surrounding materials.

Watch for:

Horizontal or vertical cracks
Stair-step cracking
Cracked bricks or masonry units
Loose masonry
Bulging walls
Missing mortar
Deteriorated mortar joints
Areas of discoloration or staining

A masonry crack should not automatically be treated as a cosmetic issue. Its location, size, pattern, and surrounding conditions can help determine whether it is associated with moisture, movement, or another underlying problem.

How ESI Can Help

ESI Waterproofing & Masonry Restoration Inc. provides commercial masonry restoration and repair, including masonry repairs, mortar joint restoration, and related building-envelope solutions.

2. Deteriorated Mortar Joints

Mortar joints are particularly vulnerable to New England weather.

Repeated exposure to moisture and freeze-thaw cycles can cause mortar to deteriorate, crack, loosen, or erode. Once joints become compromised, water can penetrate more easily into the masonry assembly.

Property managers should look for:

Recessed mortar joints
Crumbling mortar
Missing mortar
Open joints
Cracking along mortar lines
Moisture staining
Efflorescence

Repointing deteriorated mortar joints can be an important component of masonry maintenance.

The goal is not simply to make the wall look better. Proper restoration should address deteriorated joints while helping protect the masonry assembly from continued moisture exposure.

3. Efflorescence & Persistent Exterior Staining

White, chalky deposits on brick or masonry are commonly known as efflorescence.

Efflorescence occurs when water moves through masonry and carries soluble salts toward the surface. As the water evaporates, the salts can remain behind as a visible deposit.

Efflorescence does not necessarily mean that the masonry itself has failed. However, persistent or recurring efflorescence can be a reason to investigate moisture movement through the building envelope.

Other warning signs include:

Dark moisture stains
Rust-colored staining
Repeated wet areas
Discoloration beneath windows
Staining around penetrations
Interior moisture appearing near exterior walls

The important question is not simply “How do we clean the stain?”

It is:

“Why is moisture getting there in the first place?”

4. Failed Sealants Around Windows, Doors & Joints

Sealants are an often-overlooked component of commercial building maintenance.

Exterior sealants are used around:

Windows
Doors
Expansion joints
Control joints
Wall penetrations
Dissimilar materials
Masonry transitions
Building façade interfaces

Over time, sealants can shrink, crack, harden, separate, or lose adhesion.

Once the sealant joint fails, water may find a pathway into the building envelope.

Signs of Sealant Failure

Look for:

Cracked sealant
Gaps
Shrinkage
Peeling
Separation from adjacent materials
Brittle sealant
Failed joints around windows
Water staining near openings

Replacing failed sealants as part of a preventative maintenance program may help reduce the risk of more extensive moisture-related deterioration.

5. Failing Flashing

Flashing is designed to direct water away from vulnerable areas of the building envelope.

When flashing is missing, damaged, improperly installed, or deteriorated, water can enter locations where it can cause concealed damage.

Pay particular attention to flashing around:

Windows
Doors
Roof-to-wall transitions
Copings
Parapets
Masonry openings
Wall penetrations
Changes in exterior materials

Flashing problems can be particularly challenging because the visible symptom may appear far away from the actual source of water intrusion.

That is why simply repairing the location where water appears inside the building may not solve the underlying problem.

6. Concrete Cracking & Spalling

Concrete deterioration is another major concern for commercial properties throughout New England.

Concrete can deteriorate from moisture exposure, freeze-thaw cycling, corrosion of reinforcing steel, deicing salts, age, and other environmental conditions.

Common warning signs include:

Cracks
Spalling
Delamination
Exposed reinforcing steel
Rust staining
Surface deterioration
Deteriorated edges
Damaged slabs
Deteriorated balconies, stairs, or walkways

When reinforcing steel corrodes, the resulting expansion can create pressure within the concrete and contribute to cracking and spalling.

Why Early Concrete Restoration Matters

A small area of deterioration may sometimes be addressed with targeted repairs.

If deterioration continues unchecked, however, the affected area may become larger and require more extensive concrete restoration.

ESI provides commercial concrete restoration services designed to address deteriorated concrete and help commercial property owners maintain their exterior structures.

7. Deteriorated EIFS or Stucco

EIFS and stucco can provide durable exterior finishes when properly installed and maintained.

However, cracks, damaged areas, failed sealants, improperly addressed transitions, and moisture intrusion can compromise the exterior assembly.

Property managers should inspect for:

Cracking
Bulging
Discoloration
Damaged finish
Failed sealants
Open joints
Impact damage
Moisture staining

Because EIFS and stucco can conceal portions of the building envelope, visible damage should be evaluated rather than simply covered with a new finish.

ESI Waterproofing & Masonry Restoration Inc. provides EIFS repair and stucco repair for commercial properties.

8. Deteriorating PVC or Clapboard Siding

Exterior siding is another important component of the building envelope.

Damaged, loose, warped, cracked, or improperly sealed siding can create opportunities for moisture to enter behind the exterior finish.

Look for:

Cracked siding
Warped boards
Loose panels
Missing sections
Damaged trim
Failed joints
Water staining
Deteriorated areas around windows and doors

ESI provides PVC and clapboard siding replacement for commercial properties when localized or larger-scale siding replacement is needed.

9. Parapet & Coping Deterioration

Commercial buildings with masonry parapets can be especially vulnerable to water intrusion.

Parapets and coping are exposed to rain, snow, ice, wind, and temperature changes from multiple directions.

Warning signs may include:

Cracked masonry
Deteriorated mortar
Loose coping
Open joints
Water staining
Deteriorated flashing
Failed sealants
Masonry displacement

Because parapets are directly exposed to the elements and frequently incorporate multiple building-envelope components, deterioration should be addressed as part of a broader façade and waterproofing strategy.

10. Water Intrusion That Keeps Coming Back

One of the most important exterior-building warning signs is simple:

The leak keeps coming back.

If a property has repeated water intrusion around the same area, painting or patching the interior may only conceal the symptom.

Recurring leaks can be associated with:

Failed flashing
Masonry cracks
Deteriorated mortar
Failed sealants
Waterproofing deficiencies
Damaged siding
Window and door transitions
Roof-to-wall interfaces
Building-envelope penetrations

A successful repair should focus on identifying and addressing the source or pathway of water intrusion, not simply repairing the interior damage.

Why New England Weather Makes Exterior Maintenance Especially Important

Commercial buildings throughout Massachusetts, Rhode Island, Connecticut, and New Hampshire experience demanding weather conditions.

Seasonal temperature changes can repeatedly expose masonry and concrete to moisture, freezing, thawing, expansion, and contraction.

Winter conditions can also introduce deicing salts and additional moisture to exterior concrete and masonry.

This makes preventative exterior maintenance particularly important for commercial properties throughout New England.

A building that looks acceptable during a visual walk-through may still have developing problems within its exterior envelope.

Massachusetts Building Code Considerations for Exterior Building Repairs

Massachusetts commercial property owners and managers should also understand that exterior building work can involve applicable building-code requirements.

The current Massachusetts State Building Code is the 10th Edition of 780 CMR. It became effective October 11, 2024, following a concurrency period, with the 10th Edition becoming the only applicable edition beginning June 30, 2025. The code is based substantially on the 2021 International Building Code and includes Massachusetts-specific amendments.

The Massachusetts code includes dedicated provisions addressing exterior walls, masonry, structural considerations, and existing buildings. The 10th Edition’s table of contents specifically identifies Chapter 14 for exterior walls, Chapter 21 for masonry, and Chapter 34 for existing-building amendments.

For building-envelope projects, applicable requirements can depend on the property’s construction, occupancy, scope of work, location, existing conditions, and whether additional municipal requirements apply.

Massachusetts also has multiple energy-code pathways. The Commonwealth identifies a Base Code as well as optional Stretch and Specialized energy codes, with individual municipalities determining which requirements apply.

Important: Building-code requirements should be evaluated for the specific project and jurisdiction. This article is intended as general information and should not be treated as a substitute for project-specific code review, engineering, architectural services, or permitting guidance.

The Cost of Waiting Can Go Beyond the Repair

Exterior defects rarely improve on their own.

A deteriorated mortar joint can continue to allow moisture penetration.

A failed sealant joint can expose surrounding materials to water.

A concrete crack can expand.

A small area of spalling can grow.

A compromised waterproofing detail can allow moisture to reach concealed building components.

For property managers, the issue is therefore not simply:

“How much will this repair cost today?”

It is also:

“What could this defect cost if it remains unaddressed?”

That is where preventative building-envelope maintenance becomes an important part of long-term commercial property management.

What Property Managers Should Include in an Exterior Inspection

A proactive exterior inspection should consider more than just obvious cosmetic damage.

Consider documenting:

Masonry

Cracks
Missing mortar
Recessed joints
Spalling
Bulging
Displacement
Efflorescence

Concrete

Cracks
Spalling
Delamination
Rust staining
Exposed reinforcement
Deteriorated edges

Waterproofing

Moisture intrusion
Failed membranes
Deteriorated waterproofing
Problematic transitions
Drainage concerns

Sealants

Cracking
Shrinkage
Adhesion failure
Open joints

Exterior Finishes

EIFS damage
Stucco cracking
Siding deterioration
Damaged trim

Building Openings

Window perimeter sealants
Door transitions
Flashing
Masonry openings

Parapets & Copings

Cracking
Loose materials
Failed joints
Flashing deterioration
Water staining

Documenting these conditions can help property managers prioritize repairs and develop a more predictable capital-maintenance plan.

Preventative Maintenance vs. Emergency Restoration

The best time to identify exterior building deterioration is generally before it becomes an emergency.

A proactive approach can help property managers:

Identify developing defects
Prioritize repairs
Plan capital expenditures
Reduce unexpected maintenance events
Address moisture sources
Protect building materials
Improve long-term building performance
Reduce disruption to tenants
Extend the service life of exterior components

Instead of waiting for water intrusion to become a tenant complaint, property managers can incorporate exterior inspections and maintenance into their ongoing facility-management strategy.
