1. Commercial & Residential Inspections, LLC

Address: 16435 North 47th Place

Contact: (602) 320-1777

Hours: Monday-Sunday, 8:00 AM – 8:00 PM

Commercial & Residential Inspections identifies indoor biological growth by collecting air samples and visually inspecting multiple areas to locate the moisture source.

They thoroughly evaluate environmental risks caused by past water damage, connecting poor indoor air quality directly to physical symptoms like respiratory irritation.

This team also integrates specialized air quality assessments with complete property checks to give you peace of mind.

A close friend hired them after a sudden plumbing disaster, and their meticulous mold inspection caught a hidden leak inside a bathroom wall.

However, their main office sits in a residential neighborhood, which limits the number of walk-in clients they can easily accommodate at once.

Customer Reviews

Quick turnaround time

Great service and quick turnaround time for the mold report. Dave and his daughter Lisa were very professional and the pricing was reasonable. If you have a residential or commercial space and want to hire someone that’s professional and knowledgeable, reach out to Dave! I found mold in my office caused by a roof leak on Saturday. Dave was able to get me scheduled on Monday, the report came in on Tuesday and the drywall and carpet were started on Wednesday. Everything but the paint was done in 5 days.

Thank you Dave and Lisa!

2. Proinspect LLC

Website: https://proinspectaz.com/

Address: 2336 W Roy Rogers Rd

Contact: (602) 805-0202

Hours: Monday-Friday, 8:00 AM – 5:30 PM | Saturday, 9:00 AM – 1:00 PM 

Proinspect LLC conducts professional sampling and laboratory analysis, with digital reports provided independently of third-party builders. This separation helps keep the findings impartial and focused on the condition of the property.

They also offer standalone laboratory analysis with clearly listed baseline rates, giving homeowners a straightforward option when testing is the main priority. Reports can be delivered digitally on the same day and include high-resolution visual documentation.

For homeowners who need a broader property assessment, you can employ their home inspection services. After the inspection, a one-on-one video consultation is available to help clients understand the technical findings and any issues identified.

Just a heads up: their weekend availability is somewhat restrictive due to shorter Saturday operating hours.

3. Mold Inspection & Testing Phoenix AZ

Website: https://moldinspectionandtest.com/

Address: 7805 W. Mulberry Dr.

Contact: (623) 242-2966

Hours: Monday-Saturday, 8:00 AM – 8:00 PM

Mold Inspection & Testing Phoenix AZ specialises exclusively in building assessments. Their inspection-only approach helps keep their findings independent.

Their technicians assess properties for concealed moisture problems caused by issues such as monsoon storms, plumbing leaks, and condensation.

To investigate potential mould growth, they collect air trap samples and surface swabs for independent laboratory analysis.

The combination of moisture assessment and laboratory testing helps identify fungal growth that may not be immediately visible during a property inspection.

Unfortunately, they may charge an additional $200 hazardous fee for certain inspections. This can noticeably increase the cost, so it’s worth confirming whether the fee applies to your property beforehand.

4. 1st Priority Inspections

Website: https://1stpriorityinspections.com/

Address: 832 N Grace St, Scottsdale

Contact: (408) 219-7663

Hours: Monday-Saturday, 8:00 AM – 8:00 PM

1st Priority Inspections evaluates residential properties through detailed air quality assessments and careful visual examinations to uncover concealed biological growth.

When we bought an older property last spring, their mold inspection successfully identified a hidden damp spot behind the kitchen cabinets.

They employ calibrated environmental meters to check ambient air quality and surface conditions throughout the house. Combining these core evaluations with multi-hazard testing for radon, lead, and asbestos offers exceptional value.

Additionally, this team delivers analytical findings and structured reports on the same day.

That said, they provide general property evaluations rather than focusing solely on mould inspections. This may be less suitable for homeowners who prefer a company dedicated exclusively to mould testing.

Customer Reviews

Highly recommend

Great experience with 1st Priority Inspections. Tim explained the process beforehand with upfront pricing, communicated throughout the assessment and sampling inspection, and provided a detailed report with lab results quickly. This was for a mold inspection but he offers additional inspection services and is very thorough. I would highly recommend.

Timely report

Mold inspection:  Tim was excellent in getting out there during our inspection period, and providing the report in a timely manner.  The test proved to provide very helpful information to a buyer who would have otherwise not known there was toxic mold in a laundry room.
