LOCATION: Kitchen/Family Room

OBSERVATIONS:

  • Evidence of water damage is present in the ceiling. A leak occurred in the ceiling several months ago, and a section of the ceiling has been cut out.

Recommendations:

  • Replace the removed section of drywall in the ceiling, patch and paint to match surrounding surfaces.

LOCATION: Bonus Room

OBSERVATIONS:

  • The room is furnished with carpeting in average condition. Carpeting can hold mold spores for long periods of time, long after the original source of the mold growth has been removed.
  • Mold growth observed on the carpet tac strip.
  • Evidence of past groundwater intrusion was noted. A French drain has been installed and may have solved this problem.
  • Visible water staining was noted on the baseboard trim along the North wall.
  • The room is furnished with upholstered furniture.

Recommendations:

  • Remove and replace the mold damaged carpet tac strip.
  • Remove and replace the water stained baseboard trim.
  • Consider removing the carpet and replacing with a hard surface flooring such as laminate. This will greatly increase the ability to clean the area and remove settled mold spores. Removal of carpeting should be performed with HEPA air scrubbers in place. Please contact us for pricing.

LOCATION: Boy’s Bedroom

OBSERVATIONS:

  • A portable filter is in use in this bedroom.
  • The bedroom has:
    • Carpeting. The carpet is in average condition.

Recommendations:

  • See ventilation section above for recommendations to eliminate condensation.
  • Mop up any splashed water that accumulates on the bathroom floor.

Project Type > Full House Mold Inspection on Newly Purchased Home in Lake Forest Park

PROJECT SUMMARY

HOME INTERIOR OBSERVATIONS

LOCATION: Master Bedroom

OBSERVATIONS:

  • The room is furnished with carpeting in old, dirty condition. Carpeting can hold mold spores for long periods of time, long after the original source of the mold growth has been removed.
  • Condensation-based mold growth staining is present on an exterior wall where a bed was previously located.
  • The room is equipped with vinyl framed double paned windows in very dirty condition.
  • Mold growth observed on exterior wall in closet. This is often due to limited air flow and insufficient heat. Contents stored in closets can block air flow around the walls and contribute to condensation forming against cool exterior walls.

Recommendations:

  • See ventilation section above for recommendations to eliminate condensation.
  • Keep contents and furniture a minimum of 2-3 inches away from exterior walls to help prevent mold growth on these surfaces.

LOCATION: Hall Bathroom

OBSERVATIONS:

  • The bathroom has been painted with a flat or matte paint. This allows condensation to pass through the painted surface. Gloss paint prevents this more effectively.
  • Evidence of condensation and drip marks were noted throughout this bathroom.
  • Bathroom fan is of poor quality and is quite loud.

SHOWER:

  • Grout and caulking is in good condition and shows no signs of recent water intrusion.

FLOORING:

  • Elevated moisture detected in flooring adjacent to toilet. Often this is due to a slight failure of the toilet seal. No evidence of significant structural damage was observed.

Recommendations:

  • Contact a plumbing contractor to investigate the toilet seal. Replace if necessary.
  • Repaint the bathroom with a high quality gloss latex paint.

LOCATION: Middle Upstairs Bedroom

OBSERVATIONS:

  • Minor evidence of water damage was noted on the bedroom ceiling to the right of the closet. The paint is bubbling in the area where water damage has occurred.
  • The wall surfaces in this room are lath and plaster, and are unlikely to have significant mold growth behind the walls.
  • The room is furnished with carpeting in old, dirty condition.
  • Minor condensation-based mold growth staining was noted on an exterior wall above the heat register.
  • Evidence of significant dust accumulations noted throughout this present. Dirt and dust can provide a growth medium for mold to settle on, and given a humid environment, mold will blossom there.

Recommendations:

  • Remove and replace the carpeting.
  • Water damaged section of ceiling can be cleaned and repainted to match.

LOCATION: Back Upstairs Bedroom

OBSERVATIONS:

  • The room is furnished with carpeting in old, dirty condition. Carpeting can hold mold spores for long periods of time, long after the original source of the mold growth has been removed.
  • Evidence of significant dust accumulations noted throughout this present. Dirt and dust can provide a growth medium for mold to settle on, and given a humid environment, mold will blossom there.

Recommendations:

  • Remove and replace the carpeting.

LOCATION: Kitchen

OBSERVATIONS:

  • The kitchen is equipped with a high quality down draft exhaust fan built into the stove.
  • Minor water damage was noted under the kitchen sink to the base of the cabinet floor.
  • Minor visible mold growth was observed on the surface of the back wall under the kitchen cabinet. This is due to poor insulation in the wall and a damp environment.

Recommendations:

  • Ensure no leaks are present in the plumbing under the kitchen sink.
  • Consider replacing the cabinet floor that has been water damaged.

LOCATION: Living Room & Dining Room

OBSERVATIONS:

  • The room is furnished with carpeting in old, dirty condition. Carpeting can hold mold spores for long periods of time, long after the original source of the mold growth has been removed.
  • Minor staining was found on the exterior walls of the living and dining room. This appears to be marks of dirt rather than mold growth.
  • Water damage observed on the ceiling around the chimney. The water damaged area shows signs of paint bubbling and minor efflorescence. Efflorescence is not a health hazard; it is caused by salts and minerals migrating through the concrete. This occurs when moisture migrates through a masonry material and deposits minerals on the surface. These deposits are harmless, but they do indicate a minor moisture intrusion.

Recommendations:

  • Water damaged section of ceiling can be cleaned using a stiff bristle brush and soap and water. Once the surface is clean and dry, the area can be re-painted to match.
  • Remove and replace the carpeting.

LOCATION: Basement Back Bedroom

OBSERVATIONS:

  • The area is furnished with carpeting in old, dirty condition. Carpeting can hold mold spores for long periods of time, long after the original source of the mold growth has been removed. This carpeting should be removed and disposed of.
  • The bedroom is equipped with vinyl framed double paned windows with minor evidence of condensation.

Recommendations:

  • Remove and replace the carpeting.

LOCATION: Basement Bathroom

OBSERVATIONS:

  • The basement bathroom does not have a fan installed.
  • Minor staining is present on the back of the wall under the sink, but no signs of water damage or other visible mold growth was discovered.

SHOWER:

  • Grout and caulking is in good condition and shows no signs of recent water intrusion.

FLOORING:

  • The bathroom floor is tile installed over concrete subfloor. The tile appears to be in good condition.

LOCATION: Basement Front Bedroom

OBSERVATIONS:

  • Visible condensation-based mold growth noted on the baseboard trim.
  • Visible condensation-based mold growth noted on the corners of the exterior wall.
  • The carpeting has been removed and the remaining concrete is very dirty, with heavy staining on the surface.
  • Minor visible mold growth is present on the windows and window blinds.
  • All mold growth in this room is the result of condensation from poor air circulation this part of the home.

RELATIVE HUMIDITY & CO2 READINGS:

Pic1

LOCATION: Water Heater Closet

OBSERVATIONS:

  • Several alternations have been made to the plumbing in this area in the past.
  • One of the drain lines was left uncapped during past plumbing changes, which has resulted in sewer gasses entering the home. During warming weather, the odors will accumulate and become stronger. The limited ventilation in the home has resulted in accumulated odors from this source.

Recommendations:

  • Cap the open drain.
  • See ventilation section above for recommendations to eliminate accumulated odors.
