"I hired Walker's Home & Commercial Inspections because I was putting my older home on the market and wanted to know what repairs, if any, needed to be completed before selling. Mr. Walker pointed out several deficiencies. There was earth/wood contact below the kitchen window and some wiring that was done incorrectly. These items were corrected and the home is on the market. Thanks to the thorough inspection, a buyer will know the home was inspected and repairs done."

"While replacing our floors should have been an easy task, we were beyond bummed to learn that our old linoleum contained asbestos. Begrudgingly, I started calling around to get quotes on abatement and called Select Environmental on the recommendation of a friend of mine. Despite the fact that asbestos removal wasn't in my budget, I simply could not be more pleased to have found Blake and his team. From the outset, they were fast, timely, upfront, honest, and their pricing was fair. When an appointment was made for 8AM, my doorbell would ring at 7:59AM. His workers were efficient, meticulous, and courteous. By the end of our project, I almost longed to discover more asbestos so that I could use Blake and his team again. All kidding aside, I highly recommend Select Environmental and will use them again should the need arise."

"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."

Mold Testing and Remediation FAQs, answered by experts

Mushrooms do not harm your yard. In fact, they can actually help improve your lawn health by decomposing woody organic matter in your soil, and breaking it down into nutrients that feed your grass and plants.

Damp air from a humidifier can cause mold in ducts if it raises the air's humidity level too high for the duct system to handle or malfunctions, but it’s not a normal occurrence. To avoid mold trouble, set the humidistat to between 30% and 35% and inspect it often to ensure accuracy.

Yes, running your air conditioning unit too cold can cause condensation in the air ducts and built up moisture on the air filter, resulting in a breeding ground for mold and mildew. Mold and mildew growth can irritate those with respiratory issues, so it’s best to keep your AC running at a normal temperature.

Some of the most common signs of sensitivity or illness from mold include congestion, eye irritation, difficulty breathing, and headaches. These symptoms may not lead to long-term health issues. However, some types of mold, like toxic black mold, can make you quite ill. You may experience respiratory issues, skin rashes, or neurological issues after exposure because of the toxicity. Infants, people with compromised immune systems, and older adults can suffer the most severe reactions.

It’s worth it to get mold remediation as soon as you discover a mold in your home. Mold is a fungus that can be hazardous to your health and cause damage to your home and its belongings. Mold testing and inspections are the best way to know if you have a mold issue in your house. Once detected, call a professional mold remediation company immediately to get it taken care of.
