"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

Both wood-burning stoves and fireplaces can emit smoke and other combustion gases that are harmful to human health. According to the American Lung Association, wood smoke can lead to coughing and wheezing as well as long-term health impacts like increased risks for heart attacks and stroke. 

Newer models meet the modern efficiency standards set in 2020 by the Environmental Protection Agency for cleaner burning, more efficient wood stoves. Regular maintenance can also minimize smoke.

If you can locate building records, you may be able simply to see what type of tiles (or bonding agent) was used. Any flooring made between 1950 and 1989 more than likely contains asbestos. Asbestos tiles can also be slightly thicker than other tiles and often measure 9” x 9”, 12” x 12”, and 18” x 18. Black mastic was a commonly used adhesive that contains asbestos.

In most cases, cloudy tap water is safe to drink, as the cause is often harmless air bubbles. A simple test is to let a glass of water sit for a few minutes; if the cloudiness dissipates, it was likely just trapped air. However, you cannot be certain of the water's safety without knowing the cause or performing a water test. If the cloudiness is persistent, comes with yellow or brown discoloration, or is accompanied by plumbing issues, it may pose a health risk. In such cases, it is best to call a local plumber to find the cause.

Vermiculite insulation that comes from a particular mine before 1990 is likely to contain asbestos. This is particularly true in the U.S. However, not all types of vermiculite insulation contain asbestos. Since you can't detect the presence of asbestos without special equipment, it's best to assume that the insulation contains the dangerous mineral and to either leave it alone or hire a professional to handle it.

Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and—if your floors are wood—rotting.
