"When my kitchen flooded due to a broken pipe AAA insurance connected me with Redwood Restoration. Patrick responded quickly and was an absolute pleasure to work with. He was intelligent, patient, compassionate and went out of his way to help get my kitchen restored to its former glory. Patrick s crew was also top notch... JJ and Miguel get a special thank you for their excellent work! At first I used Redwood Restoration because my insurance company referred them to me...but I would call them back in a second the next time something happens because they are the best!!! Thank you again for all you did for me. Linda H. Santa Rosa"

"I was not surprised to read and see that Landmark construction energy crew have such an excellent reputation online, as I would also recommend them and their jobs. We hired them to paint the exterior and interior of our house few months ago and they did a remarkable job. The job went on without any problem or issues even though we were not at the house part of the time due to a trip that we went on. The quality of the work that they did get into a minor delay and it took longer than expected, but it was not because of their fault. Before we hired Landmark construction energy crew, we had other contractors in at the same time and they were getting in each other’s way. When the paint project was completed, we were very satisfied with the final results. Our house looks brand new now and we can't say enough good things about how beautiful it came out. Charlie was the nicest and lovely man during the project and he was very in-depth, extremely detail oriented and he didn’t cut corners in any way. Charlie with his workers went above and beyond on our job to make us pleased and we felt like they treated our house as if it was his own. Charlie took pride in the job that they were doing and the final work can show that very clear. It’s sad to mention but those days, it’s very hard to find workers like that anymore. We also were very pleased with Jose (the main painter that ran the show when Charlie was not around). Joe stayed in close contact with Charlie and us as the job developed. The pricing for this whole work was very fair and they were willing to work around our though schedule. If you’re in need of a very good and reliable painting company, one who values your business and truly wants you to be satisfied when they are done, then hire Landmark construction energy crew. We never felt they just wanted to get the money and be done. Their first priority was our happiness! Thanks, Charlie and especially Jose."

"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."

Biohazard Remediation FAQs, answered by experts

When you smell something, it’s because the particles of what you are smelling are floating through the air. If you smell mold, it means that it’s airborne, and whether or not it’s harmful depends on the type of mold. It’s very hard to tell the difference between molds, even with the internet to guide you. Call a professional as soon as you see mold, they will test it, remove it, and make sure you aren’t breathing anything harmful.

Toxic drywall has a sulfur smell, similar to rotten eggs or poop. It’s often a sign that the drywall mud is expired, there’s mold or mildew growth, or there’s a leak in your home. Drywall can also absorb moisture during storage, transportation, or installation, resulting in a distinct musty odor.

Many caulk alternatives are safe for use in kitchens and food preparation areas, provided you apply them correctly and let them cure for the right amount of time. If you’re unsure about this step, call in a pro to do it for you. Silicone putty and caulk strips are often used around sinks and countertops due to their waterproof and flexible nature. Always choose products labeled as safe for kitchen use and follow the manufacturer's instructions for proper application and curing.

Figuring out why you have a musty smell in your house is the first step to getting rid of it. Mold or mildew is most likely causing the unpleasant odor. People use these terms interchangeably, but they’re actually different.

Mold is a fungus that loves to grow in moist, humid places. It’s typically black or green and has a raised, uneven texture. Stay vigilant for signs mold may be growing in your home. 

You’ll find mildew growing on your shower walls and in your bathroom’s nooks and crannies. It’s a specific type of mold that grows flat. Mildew is usually white, gray, or yellow.

Powdery mildew is exactly like it sounds—a widespread mold that looks like baking soda or talcum powder. It’s usually seen on plants and spread in warm climates, which is why many people first discover this issue in their home greenhouse. Over time, plants have become resistant, but if you see it spreading, baking soda and water can eliminate many cases. Otherwise, consider neem oil or fungicide.
