Lead Paint Inspections

We are accredited by the Maryland Department of the Environment (MDE) to perform Risk Reduction lead paint inspections and can walk you though the process. The Maryland Lead Risk Reduction in Housing Law requires lead paint inspections for certain situations including rental units constructed prior to 1978. Please read the MDE Lead Registration page and the MDE Rental Housing Fact Sheet (PDF) for additional information.

Full Risk Reduction Inspections

Please follow the steps below and review our Lead Paint Inspection Guide (PDF) to have your lead paint inspection go as smoothly as possible and to avoid additional fees for re-testing. Use our Book Now page when you are ready to set up an appointment. We can usually fit you on the schedule within a few days.

Note: We are required by law to notify the MDE at least 24 hours prior to a lead paint inspection. They can and will show up at the property at the appointment time to audit the inspection.

1. Tracking Number
As part of this process, you will need to obtain a tracking number if you don’t already have one. To obtain a new Tracking Number or to find the Tracking Number already assigned, call MDE at 410-537-4199, email mde.leadreg@maryland.gov, or visit the MDE Lead Rental Registry Property Search. We will need this number to generate and issue your Certificate.

2. Visual Inspection – Exterior
The first part of the lead paint inspection is a visual inspection of the ENTIRE EXTERIOR including walls, windows, doors, door frames, trim, soffit, fascia, gutters, downspouts, porches, posts / columns, ceilings, railings, and steps on both the main structure and any outbuildings accessible to tenant(s). There can be no deteriorated paint conditions (peeling, chipping, cracking, etc.) regardless of the age or type of paint in order for the inspection to proceed to the interior inspection.

3. Visual Inspection – Interior
If the exterior passes the visual inspection, we will then perform a visual inspection of the ENTIRE INTERIOR of the home including baseboards, doors, door frames, walls, ceilings, enclosed porches, window jambs / frames / sills / wells / sashes, cabinets, and radiators. Areas inspected include basements and any other spaces that are directly accessible. All doors must be unlocked and all windows that are intended to open must be able to be opened. There can be no deteriorated paint conditions (peeling, chipping, cracking, etc.) regardless of the age or type of paint in order for the inspection to proceed to wipe sampling.

4. Dust Wipe Sampling
The last part of the inspection is dust wipe sampling. In houses with wooden windows, two dust samples are taken per room. If newer windows are present, only one sample per room is required. The MDE definition of a room includes bedrooms, bathrooms, hallways, basements, etc. Samples may be taken from window sills, wells and/or floors at our discretion. If no window is present, a floor area may still be tested. It is very important to make sure the house is properly cleaned prior to this portion of the inspection (see below).

  • General Cleaning Tips: Lead dust needs a detergent cleaner to break the bond with surfaces. Bleach or glass cleaners should not be used. Any cleaning and painting must be completed at least one hour prior to the inspection. Once cleaning has been performed, it is recommended that all human and animal traffic be limited or prevented before and during the inspection.
  • Cleaning Bare Floors: Should be cleaned using a High Efficiency Particulate Air (HEPA) vacuum followed by mopping with a new mop head and a mild detergent with clean water for each room. Unfinished concrete floors in basements are very difficult to clean and a frequent cause of failure. The best course of action is usually to clean then paint these floors with a garage-type epoxy paint that will seal in any old dust and make the floor easier to clean. All floors should be “white glove” clean.
  • Cleaning Carpet: Should be cleaned using a HEPA vacuum in one direction and then again in the perpendicular direction.
  • Cleaning Windows: Window wells and window sills should be cleaned with a HEPA vacuum then with paper towels and a mild detergent solution. The window well is the area where the bottom of the sash hits when the window closes and is a very difficult area to obtain a “pass”. When wiping, do so in one direction (not back and forth). This well area needs to be spotless.

The Full Risk reduction certificate that is issued will expire at tenant turnover. A new inspection must take place prior to the new tenants moving into the property.

Lead-Free Inspections

At this time we do not offer lead-free inspections due to low demand. These inspections are done using an XRF gun to analyze all layers of paint on every surface inside and outside the home. Unless a house built prior to 1978 has been completely remodeled down to the studs, there is a high likelihood of failure. If lead is found, those surfaces will have to be removed and the house will need to be re-tested. Alternatively, the owner may have to face the additional cost of a Full Risk Reduction Inspection as well.

$225 typically covers a small single-family house or row home with vinyl windows. This includes the interior/exterior lead paint inspection, 10 dust samples, and all associated lab fees, shipping, and a Risk Reduction Certificate.

$15 for each additional dust wipe sample. Costs vary based on the size of the property and types of windows. Each room including hallways and bathrooms requires 1 sample (2 in houses with old wooden windows). Turnaround is about 5 business days but rush processing is available for a fee.

Discounts for repeat customers, multiple units, re-inspections, or when combined with a rental inspection.
