"I can't say enough about how great Upper Left is - I highly recommend them. We reached out to Upper Left based on a co-worker's recommendation after a mistake in an HVAC install on our second floor caused water damage to the second story and first floor just below it. They came out quick, devised a plan and got the dry-out going. They were here daily to follow up and their communication with both me and my insurance agent was amazing. Their work and professionalism is exceptional, but more importantly you could tell they really wanted the best outcome for me and my family."

"Teman Montgomery was totally professional; extremely knowledgeable, forthcoming about his observations, and intensely thorough. He arrived early to orient this buyer as to the procedure, and then methodically and with great care explained in common language the details as he worked through the house. After receiving and reviewing his report, with copious photos and recommendations for attention/repairs of defects he found, I am blown away by the whole process and would recommend this company to everyone who is looking for a detail oriented inspector with a stellar work ethic. Wow."

Mold Testing and Remediation questions, answered by experts

It can be challenging to know if mold is growing behind walls without knocking them down. If the walls show signs of water damage (discoloration, water stains, or peeling paint) or there’s a musty odor, it’s possible mold is growing. Know the difference between signs of water damage vs. termites because termite infestations are sometimes mistaken for water damage. A more subtle sign might be your own health: If you’re constantly not feeling well or are sneezing, scratching your eyes, or coughing when in a specific room, you could have mold.

There are two types of mold symptoms in the home: visible mold and unexplained health issues. If you have allergies out-of-season, brain fog with no other obvious cause, constant congestion, and other such symptoms, you may have a mold problem. Oftentimes you can smell mold in your home, even if you can’t see it. 

Mold on window sills is common, especially in damp or poorly ventilated areas. Windows are prone to condensation, which creates the moisture mold needs to grow. Dust, dirt, and other debris on the sills can further feed mold spores. While it’s not unusual, it should be addressed quickly to prevent further growth and potential health risks.

Mold remediation is required if the mold growth covers more than 10 square feet of an area or the mold spore concentration is above 500 spores per cubic meter of air. You should also seriously consider remediation if there is a lot of water damage along with mold growth or if you suspect your HVAC system has been contaminated with mold. Remediation is also crucial if the mold damage has been caused by sewage or other contaminated water.

Toxic drywall has a sulfur smell, similar to rotten eggs or poop. It’s often a sign that the drywall mud is expired, there’s mold or mildew growth, or there’s a leak in your home. Drywall can also absorb moisture during storage, transportation, or installation, resulting in a distinct musty odor.
