Close-up of termite damage on wooden beams during an inspection.

Termite Activity Inspection

Why It Matters:

Termites are silent destroyers, compromising the structural integrity of a building long before visible damage appears. Undetected infestations can weaken wooden framing, leading to costly repairs.

How MARCO Services Detects It:

Our inspections identify early signs of termite activity, including wood damage, and mud tubes. Using moisture meters and probing tools, we assess affected areas and recommend mitigation strategies to protect your investment.

Rotting wood with visible moisture damage on a structural beam.

Wood Rot Inspection

Why It Matters:

Wood rot weakens structural components, leading to instability in framing, flooring, and exterior elements. If left unaddressed, it can cause costly and hazardous failures.

How MARCO Services Detects It:

We inspect moisture-prone areas, probing suspect wood for softness and testing moisture levels. Infrared cameras and moisture meters help us determine if conditions are conducive to further decay, allowing us to recommend preventive and corrective measures.

Blistering and cracks on a built-up roof surface.

Blistered Built-Up Roof Inspection

Why It Matters:

Roof blistering compromises waterproofing, leading to leaks, insulation damage, and premature roof failure.

How MARCO Services Detects It:

We evaluate the roofing membrane for trapped moisture, poor adhesion, and aging. Infrared thermal scans pinpoint areas where water infiltration has weakened the roof’s structure, allowing for targeted repairs before major failures occur.

Crumbling concrete masonry unit (CMU) wall with structural shifting.

Crumbling and Shifting CMU (Concrete Masonry Unit) Wall Inspection

Why It Matters:

A shifting or crumbling CMU wall indicates foundation problems, improper drainage, or material deterioration. These issues can compromise a building’s stability.

How MARCO Services Detects It:

We assess cracks, mortar joint degradation, and alignment shifts. Using precision measurement tools, we determine if movement is ongoing and provide recommendations for reinforcement or repair.

Corroded furnace flue pipe showing rust and deterioration.

Furnace Flue Pipe Corrosion Inspection

Why It Matters:

A corroded flue pipe can lead to carbon monoxide leaks, posing serious health risks.

How MARCO Services Detects It:

We inspect flue pipes for rust, holes, and improper venting. Carbon monoxide detectors and gas analyzers help confirm safe furnace operation, ensuring compliance with building codes and safety regulations.

Wood truss with a missing connector plate, affecting structural support.

Truss Defect: Missing Plate Inspection

Why It Matters:

A missing or damaged connector plate weakens roof trusses, risking structural failure under load conditions.

How MARCO Services Detects It:

Our inspection includes visual assessment, load calculations, and structural integrity checks to identify weak points. We provide recommendations for reinforcement or replacement as needed.

Loose slate shingle on a pitched roof, posing a potential hazard.

Slate Shingle Drop Inspection

Why It Matters:

Loose or fallen slate shingles expose a roof to water damage, accelerating structural deterioration.

How MARCO Services Detects It:

We inspect for misaligned, cracked, or missing slate shingles and assess underlying roof decking for damage. By detecting loose fasteners and improper installation, we help extend your roof’s lifespan.

Visible cracks in a foundation wall indicating movement or settling.

Foundation Wall Cracking and Movement Inspection

Why It Matters:

Cracks and movement in foundation walls indicate soil instability, water infiltration, or structural deficiencies, potentially leading to costly repairs.

How MARCO Services Detects It:

We assess cracks for depth, width, and displacement, determining whether they indicate minor settling or major structural failure. Monitoring techniques help track ongoing movement, guiding appropriate repair solutions.

nspector using a moisture meter on a wall to detect hidden water damage.

Moisture Measurement Inspection

Why It Matters:

Excess moisture can lead to mold growth, wood rot, and structural damage. Identifying hidden moisture issues prevents long-term deterioration.

How MARCO Services Detects It:

We use moisture meters, infrared cameras, and humidity sensors to locate excess moisture in walls, floors, and ceilings. Our findings help mitigate risks before they cause major damage.

Commercial building roof inspection in progress with visible wear and tear.

Commercial Roof Evaluation

Why It Matters:

A failing commercial roof can lead to water damage, energy loss, and costly business disruptions.

How MARCO Services Detects It:

Our inspections include thermal imaging, core sampling, and drainage assessments. By identifying weak spots and ponding water areas, we help businesses avoid unexpected repairs and extend roof life.

Shingles lifted or missing due to wind damage after a storm.

Wind-Damaged Shingle Inspection

Why It Matters:

Wind-damaged shingles leave a roof vulnerable to leaks, insulation damage, and further deterioration.

How MARCO Services Detects It:

We assess shingle integrity, fastening strength, and underlayment conditions. Our recommendations help prevent costly damage from future storms.

Fungal growth and mold visible on an indoor wall surface.

Fungal Growth Inspection

Why It Matters:

Fungal growth, including mold and mildew, can degrade materials and pose health risks.

How MARCO Services Detects It:

We conduct air quality testing, surface sampling, and moisture analysis to locate fungal growth sources. Proper remediation planning ensures long-term protection.

Signs of water penetration on a foundation wall with damp spots.

Foundation Moisture Penetration Inspection

Why It Matters:

Water infiltration weakens foundations, leading to structural movement and mold issues.

How MARCO Services Detects It:

We identify seepage points, test drainage systems, and measure hydrostatic pressure around the foundation to determine the best waterproofing solutions.

Improper breaker connection inside an electrical panel box.

Improper Breaker Connection Inspection

Why It Matters:

Poor electrical connections create fire hazards, voltage drops, and circuit failures.

How MARCO Services Detects It:

Using thermal imaging and electrical testing equipment, we inspect panel wiring for loose, overheated, or improperly sized breakers to ensure compliance with safety codes.

Wood rot at the bottom of a window frame due to prolonged moisture exposure.

Wood Rot at Window Inspection

Why It Matters:

Rotting window frames compromise insulation, lead to air leaks, and allow moisture infiltration.

How MARCO Services Detects It:

We check for soft wood, peeling paint, and high moisture levels. By identifying early-stage decay, we help prevent expensive replacements.

Foundation wall shifting with misaligned blocks and visible cracks.

Foundation Wall Movement Inspection

Why It Matters:

Foundation movement can lead to uneven floors, cracked walls, and structural failure.

How MARCO Services Detects It:

We measure shifting with laser levels, crack monitors, and soil stability analysis to determine necessary stabilization techniques.

Foundation wall repair site with reinforcement materials.

Foundation Wall Repair Services

Why It Matters:

Neglected foundation damage can lead to severe structural problems, making early intervention crucial.

How MARCO Services Addresses It:

We provide reinforcement solutions, including carbon fiber strapping, wall anchors, and epoxy injections to restore foundation integrity.
