What We Inspect

Everything we look at, and why it matters.

Every standard inspection meets or exceeds Maryland's standards of practice (COMAR 09.36.07). If there's something we can't safely reach, it doesn't get quietly skipped. We write it down, say why, and tell you what to do about it.

System by system

Twelve systems, top to bottom.

Here's what we check in each one, and what we tend to find in houses around here. Maryland's housing stock has its own habits, and knowing them is most of the job.

What we check
  • Shingle condition, age and layers, walked when it's safe to
  • Flashing at chimneys, skylights, walls and plumbing vents
  • Gutters, downspouts and where the water ends up
  • Signs of past leaks, checked again from the attic side
What we often find in Maryland homes

Asphalt roofs 18 to 25 years old with granule loss and curling on the south-facing slopes.

Chimney flashing patched with roofing tar instead of proper step and counter flashing.

What we check
  • Insulation type and depth across the whole floor
  • Soffit, ridge and gable ventilation, and whether air can actually move
  • Bath and kitchen fans vented outdoors, not into the attic
  • Roof sheathing for staining, frost marks and rot
  • Wiring, junction boxes and signs of pests
What we often find in Maryland homes

Soffit vents blocked by blown-in insulation, which traps winter moisture under the roof deck.

Bath fans venting straight into the attic, leaving mildew on the sheathing above.

What we check
  • Foundation walls for cracks, bowing and displacement
  • Beams, posts, joists and any cut or notched framing
  • The sill plate, where the house sits on the masonry
  • Past repairs: piers, wall braces, sistered joists
What we often find in Maryland homes

Horizontal cracks and inward bowing in block walls, common in 1950s to 70s homes on clay soil.

Stair-step cracks in block that are old and stable and only need watching.

Vertical crack running through a concrete foundation wall

What we check
  • Soil slope along the foundation
  • Downspout extensions and discharge points
  • Window wells, covers and drains
  • Driveways, walks and patios that pitch toward the house
What we often find in Maryland homes

Downspouts emptying right at the foundation. Often the cheapest fix for a wet basement.

Mulch and soil built up against the siding over the years, hiding the sill.

What we check
  • Panel interior, breaker sizing and double-tapped breakers
  • Service entrance, grounding and bonding
  • A sample of outlets for polarity, grounding and GFCI protection
  • Visible wiring, including aluminum branch circuits
What we often find in Maryland homes

What we check
  • Age, read from the serial number

  • Gas venting and combustion air
  • Corrosion and leaks at the base and fittings

What we check
  • Siding, trim and caulking
  • Deck ledger attachment, footings and railings
  • Garage door auto-reverse and fire separation to the house
  • Porches, steps and walkways
  • Detached garages and sheds, where accessible

What a standard inspection leaves out.

These take different equipment, a lab, or a separate license. We list them here so nobody assumes they were covered.

Most can be added to the same visit. If you're not sure you need one, call and we'll tell you straight.

  • Sewer lateral / camera scope
    We don't run a camera through the main line out to the street.

  • Septic systems
    Tank, baffles and drain field need a septic inspection.
    Add this
  • Wells and water quality
    Well equipment and lab testing of the water itself.
    Add this
  • Anything hidden behind walls
    We can't see inside finished walls, floors or ceilings. When something points to a problem, we say where to open up.
    Ask us
  • Pools and spas
    Pumps, filters, heaters and the shell.
    Add this
  • Radon, mold and lead

Getting ready

A little prep makes for a better inspection.

Most gaps in a report come from a locked door or a blocked panel. Tick things off as you go, or print the list for the fridge.
