"We received the phone number of this company from a friend that hired them and he was able to reduce his utilities bills by doing an efficiency audit that includes covering all the openings at the house (windows, HVAC, Doors etc.?.) and then with a machine, running the test and to see from where the house is losing most of the energy and to perform a repair that will prevent that in the future. Ezra and his team of workers came to perform the test and to see what need to be repaired or improved. The audit took close to 5 hours and then the machine that they used worked for additional 2 plus hours. After that was completed, we saw clearly that the problem was the windows and the HVAC. Ezra recommended us to perform a repair to both of them and then to run the test again. After the workers of them finished the repair, Ezra came once again and did the test. He was pleased with the results and so as we. During all the work, we saw how it was before and how it was after. We do recommend this company for that type of work! They are professional and honest people to hire and they carry all the relevant licenses as well."

Mold Testing and Remediation FAQs, answered by experts

Many types of mold spores and fungi spores are constantly present in the air, but they need a friendly surface and moisture to grow. Should some of these spores land on paper or wood with significant moisture present—such as drywall with a paper cover that is soaking up water from a leak—mold or fungi could begin growing. Dampness from leaky pipes, condensation on windows, leaks in a roof, flooding in a basement, or high, prolonged humidity in a small area all can create the excess moisture that mold and fungi need to grow in your home.

Yes, air duct cleaning can remove mold from the interior lines of HVAC systems. Professional air duct cleaning companies use tools and methods like brushes, cleaners, and vacuums to remove mold from air ducts. For successful mold remediation, it is essential to hire a reputable and experienced air duct cleaning service. Keeping your air ducts clean can also help prevent the conditions that allow mold to grow and thrive in your ductwork.

Yes, you can use bleach to remove mold from your aluminum siding, but it’s a powerful cleaning agent, so make sure it’s diluted with water first. A solution of one part bleach and four or five parts water works well. But it’s still a good idea to start by cleaning a small, inconspicuous area of the siding to make sure that the solution doesn’t cause damage or discoloration. 

Yes. Black stains are more than an eyesore. Some black stains can pose health concerns, especially for those with asthma, allergies, or other respiratory conditions. Some stains can also damage the brick’s structural integrity, harming the mortar and resulting in more expensive repairs.

While mold in the bathroom can appear black, it isn’t always the dangerous black mold strain Stachybotrys chartarum. This type of mold typically appears after a flood or a long-term leak. If you suspect black mold, you should get it tested by a local mold testing service to determine whether it’s safe to remove yourself.
