"We called Silva’s Painting & Construction yesterday to reinforce two shelves that were sagging. They came and fixed them right away. Then we asked if they could construct additional shelves for our custom storage cabinets in our garage. They took measurements and a sample and constructed them in a very short amount of time. Silva’s and sons, Giovanni and Alex along with their amazing father, Sergio, have been wonderful in helping us with our move to another neighborhood and all the adjustments needed. Highly recommend and endorse this business."

"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

It depends on the type of AC unit and the extent of the mold growth. For example, if you have a small amount of mold in your central air conditioner, it’s worth cleaning it to protect your HVAC system and your health. In situations like these, you can often remove the mold yourself in a couple of hours. On the other hand, if you have a portable AC unit with a severe mold problem, it makes more sense to buy a new one. On average, replacing a portable AC unit costs $100 to $500.

Visible growth, musty odors, and water damage are common indicators.

Yes, both mold and mildew can grow under outdoor rugs if they are exposed to water or humidity for a prolonged period of time. This is why frequently cleaning an outdoor rug and checking its state is important.

A mold inspection costs an average of $660, with a typical range between $300 and $1,025. However, costs can be as low as $150 or as high as $2,800 depending on several factors. These include the size of your home, the type of mold, the extent and accessibility of the affected area, your location, and the number and type of samples required. Hard-to-reach areas like air ducts, crawl spaces, and wall cavities can increase the cost. Specific tests have different prices; for example, swab testing typically costs $200 to $300 per area, while more extensive air testing can range from $250 to $700. A thorough inspection is crucial for determining the scope of the problem and identifying the best remediation method.

Mold damage devalues a home in two ways: monetarily and emotionally. The numerical amount of mold damage devaluation can be 20% to 37%, which is substantial when house prices are often over $250,000. The second factor to consider is the emotional one: many buyers are hesitant to purchase a home that either has, or had, significant mold damage. For these reasons, it’s very important to deal with any mold issues immediately.
