"We decided to remodel our outdated bathroom, and McCormick Home Builders was a fantastic choice. Khaled and the team delivered high-quality work within the timeline and our budget. Every detail, from the tile work to the lighting, was beautifully done. They communicated well throughout, keeping us informed at every step, and the end result was truly a spa-like bathroom we can enjoy daily. We’d love to work with them again!"

"It went very well.  I contacted him initially in late November.  He was busy and so was I so we scheduled the work for 12/28.  That day he called early to tell me he would be a little late.  He arrived and went right to work.  He tore off our old wallpaper and removed the under layer.  Then he applied a coat of plaster to the entire wall.  He applied it very smoothly so there was no waste and little sanding needed.  He had us put a heater and fan blowing on the wall to dry it thoroughly.  He came back the next day and sanded the wall.  That only took about an hour.
He was thorough, quick and efficient.  I was happy with the work and would definitely recommend him to others.

"I am very pleased with the service provided by Service King. They were prompt, courteous, professional, polite, and friendly. Everything looks and smells great. I am especially pleased with my sofa. It is a light yellow color and cannot be cleaned with water which is why I had it cleaned professionally in the first place. Tony was honest about what could be done with it since this was the first time it has been cleaned since I've owned it. It looks so much better and smells great. Everything was completed in about an hour and a half and dried in about four hours. Deorderizing of our carpets was offered at a very resonable price and he even cleaned our bedside rugs for free.

"Russell successfully found and removed mold from behind my toilet. The mold was pretty bad. He made sure the area was confined before removing the mold. He did an amazing job and we feel safe utilizing the bathroom again. He was very professional and took the time to explain what steps he needed to take. I will recommend him to my family and friends. His price beat other quotes I received."

Mold Testing and Remediation FAQs, answered by experts

Mildew is a type of mold that forms in areas of excessive moisture and poor ventilation. Although it commonly exists in household air, it can’t take hold and spread if a surface is clean and dry. Generally, if you have any mildew or mold issues, it’s because the humidity in either your house, room, cabinet, or cupboard is above 50 percent. Common areas where you’ll find mildew are around water sources, which is why it’s commonly found near showers and in kitchen sinks.

Mold can come back after cleaning, especially if the conditions are right. Mold loves moist environments, so if you clean a piece of furniture, then put it back in a humid area, the mold can return. Mold may also return if you missed an area during cleaning. A professional mold remediation company can help ensure that the mold is gone for good.

Bad odors and actual, visible mold aren’t the only ways to tell if your floorboards are suffering from too much moisture. Everything from high humidity to direct contact with water can cause wood to buckle, warp, peel, and discolor. Spotting one or more of these signs could be a clue that you’re dealing with mold. 

While water in your basement is unlikely to make you sick unless it’s coming from a sewage backup, mold is likely to start to grow in wet areas within 24 hours, and mold can make you sick. According to the Centers for Disease Control and Prevention (CDC), inhaling mold spores can cause allergy symptoms, including runny nose, itchy eyes, difficulty breathing, wheezing, and itchy skin. Individuals with pre-existing respiratory issues like asthma and immunocompromised individuals are at an elevated risk of symptoms when inhaling mold spores.

White mold is generally considered less harmful than black mold, which can be more toxic due to the mycotoxins it produces. However, white mold can still be harmful, particularly for individuals with mold allergies, asthma, or other respiratory conditions. Exposure can cause symptoms like nasal stuffiness, throat irritation, coughing, or skin irritation, and it can exacerbate existing health issues. Because any type of mold can pose health risks, all mold infestations should be treated seriously. Prompt remediation is necessary, and you should take proper precautions, such as wearing protective gear and using appropriate cleaning agents, when dealing with it.
