ALP Inspections in Baltimore: Pre-Purchase Home Inspections with Thermal and Moisture Detection
ALP Inspections is a residential home inspection company operating in the Baltimore metro area that combines standard structural assessment with advanced diagnostic tools, specifically thermal imaging and moisture detection equipment, to identify hidden defects before purchase.
What ALP Inspections actually is
ALP Inspections conducts pre-purchase home inspections for buyers in Baltimore and surrounding counties. The company performs the visual and mechanical evaluation typical of any NAHI-certified inspector (roof condition, foundation, electrical, plumbing, HVAC, attic, crawlspace), but distinguishes itself through the routine use of infrared thermal imaging and moisture meters on every inspection. These tools reveal temperature differentials that suggest insulation gaps, air leaks, or water intrusion that a walk-through alone would miss. The inspector attends the inspection and produces a written report within 24 hours, delivered digitally.
Services and pricing
ALP Inspections charges a flat fee of $475 for a standard inspection of a home under 3,000 square feet in Baltimore County or the city of Baltimore; homes between 3,000 and 5,000 square feet run $550. This is roughly in line with or slightly below the Baltimore median of $500 to $600 for a comparable inspection without thermal imaging. The thermal imaging and moisture detection are included in the base fee, not an upsell. Additional services include radon testing ($150), mold air sampling ($225), and septic system evaluation ($300 for properties outside city lines). Pricing should be confirmed at time of quote, as inspections for homes outside Baltimore County or in specialized structures (historic properties, condominiums) may adjust.
How ALP Inspections compares to other Baltimore-area options
Most Baltimore home inspectors (including franchises and independents through Baltimore's Yellow Pages directory) charge similarly on base price but do not include thermal imaging as standard. A buyer can add thermal imaging separately through many inspectors for $100 to $200 extra, making ALP's all-in fee competitive if you value that diagnostic layer. Other full-service inspection companies in the region, such as those affiliated with national franchises, often emphasize fast turnaround and brand consistency but operate on a higher volume model. ALP is smaller and owner-operated, meaning less scheduling flexibility but typically direct access to the inspector for follow-up questions. If your home is historic (pre-1900 construction common in Canton, Federal Hill, or Fells Point), some inspectors specialize in period-specific concerns like plaster, lead paint, or hidden structural issues; ALP's thermal tools are less relevant to those concerns than they are to modern insulation problems.
Who ALP Inspections suits and who it does not suit
ALP is well-suited to first-time buyers concerned about energy efficiency and hidden moisture (particularly relevant in Baltimore's humid climate and older housing stock), and to buyers purchasing 1980s-to-2010s construction where insulation defects and air leaks are common failure points. Investors buying rental properties also benefit from the moisture data, which signals costly future repairs. The service is less necessary if you are purchasing a newly built home with builder warranties, or if your inspector is already the one you trust and who already includes thermal imaging. It does not offer pest inspection, mold remediation advice beyond identification, or structural engineering analysis; those typically require separate specialists.
What the first inspection involves
Once you schedule, provide the property address and estimated square footage. The inspector arrives at the agreed time and conducts a walk-through lasting 2 to 3 hours for a typical home. You may be present (encouraged for buyer education). The inspector visually examines the roof, attic, basement or crawlspace, electrical panel, furnace, water heater, plumbing fixtures, and walls and ceilings for signs of damage. Thermal imaging is performed on exterior walls, attic access points, and any areas showing visible damage. A moisture meter is applied to suspect spots, particularly around windows, under sinks, and in basements. Photos are taken throughout. Within 24 hours, you receive a PDF report organized by system, with photos, noted defects, and repair priority guidance. Many reports note whether an issue requires immediate specialist follow-up (e.g., "recommend licensed electrician evaluate outlet," "consult roofer regarding shingles").
Hours, parking, and logistics
Inspections are scheduled by appointment; hours are generally Monday through Saturday, 7 a.m. to 6 p.m., though weekend and early-morning slots fill quickly during spring (peak home-sale season in Baltimore). Confirm availability when requesting a quote. The inspector meets you at the property; parking is your responsibility and typically on-street or driveway, depending on the neighborhood. Reports are delivered via email; hardcopy is available on request. Inspections must be scheduled at least 3 to 5 business days out; rush appointments may carry a $75 surcharge.
ALP's routine use of thermal and moisture diagnostics on every Baltimore inspection means you get defect detection beyond the eye, relevant to the region's climate and aging housing stock, without paying extra.
