"We decided to remodel our outdated bathroom, and McCormick Home Builders was a fantastic choice.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

A stain from a water leak will usually be brown and concentrated in a single area where the water is originating from. You may find it under a damaged section of roof, under an upstairs bathroom, or beneath your HVAC system. Stains from condensation are more likely to be widespread since they don’t come from a single point of water intrusion. Condensation stains also look blotchy and may smell musty, and they won’t be concentrated in a single area on your ceiling.

You’ve stored your coats away all summer long, but now that the temperatures drop, you notice they smell weird as you pull them from storage. What’s the deal? If your clothes smell weird after you stored them, they may have been in a moist, dark environment for several weeks or months. This environment is ideal for mildew growth, which can make clothes smell musty.

If you suspect black mold is inside your walls, do not punch a hole in the drywall yourself to look. Call a mold inspection expert to help you. Some signs of a potential black mold infestation inside the wall include an unexplained musty, damp smell. Some people liken it to rotting vegetables. You may smell it most strongly through a wall outlet. If you and your family are experiencing constant coughing or symptoms that feel like an unexplained allergy, it could indicate black mold behind a wall.

Black mold and wood rot are both types of fungi that thrive in damp areas, but they are distinct issues with different consequences. Wood rot specifically refers to the decay of wood caused by fungi, which compromises the wood's structural integrity. Black mold, on the other hand, is a fungus that grows on the surface of materials, including both rotting and non-rotting wood. The primary difference is their impact: wood rot affects the wood's structure, while toxic black mold is a health hazard. Inhaling black mold spores can cause severe respiratory issues, whereas wood rot spores are generally not harmful to people. Because mold can grow on rotting wood, the two issues can be interconnected, but they are not the same.

Yes, mold can grow on nonporous surfaces. Mold is extremely resilient and can survive just about anywhere. However, mold will not grow as quickly on a nonporous surface as on a porous one. Additionally, the nonporous nature makes it easier to remove. Keep the countertop clean and properly maintained, and you shouldn’t experience mold growth.
