"Foundation Repair - our house had to be raised about 3 inches. Frank and his crew were very professional, kept to their schedule. Frank spent extra time with my parents to explain the scope of work and minimize the disruption to their lives. His bid was very thorough and he was upfront with the fact that there could be additional cost based upon what the crew found once they exposed the foundation wall. Would definitely use him again."

Dry-rot, Water or Pest Damage - Major Repair

"AHS is ok. They cover repairs of most everything under the roof of your house. The companies that contract with them are not always the best. You call AHS with the issue, they send a fax to the repair company and give you the contact info. If they don't contact you within 24 hours, you call them. Sometimes they answer, sometimes they don't. When they arrive (usually three days or so later), they service the item. if it has issues within the 90 days, you call AHS again, they are sent out with no charge. If the serviceman decides the unit is unrepairable, AHS will allow you to choose a replacement from their listing (usually not as good as what you have) they will install and remove your old item, or give you wholesale amount to buy and install your own. Prices vary on what you want covered and what you want the copay to be, plus where you live. For me it is 49.99 per month with a 75.00 time of service order. You can have more than one item serviced at the same time under the same fee. If you have a SEAR product the repair guys are great. Not that wild about the other ones they send out. But it is a big savings compared to calling someone on your own. The cost of service is only the 75.00 copay."

"I would highly recommend Greg Hill. He’s a great guy and he knows what he’s doing. We appreciate all the work he did on our new church project. He took a 112 year old building and turned it into a modern day sanctuary, kids church and offices. We are totally loving it."

Mold Testing and Remediation FAQs, answered by experts

Window sill mold can be harmful, but the severity depends on the type. Common household molds like Cladosporium or Aspergillus can trigger allergies, respiratory issues, or worsen asthma symptoms. However, black mold (Stachybotrys) can produce mycotoxins that can harm your health. Even less toxic molds should be addressed promptly to prevent health risks and property damage.

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.

Signs of mold sickness often manifest as respiratory issues, including coughing, wheezing, shortness of breath, and sneezing. You might also experience symptoms that resemble allergies, such as itchy eyes and sinus infections. Other telltale signs include skin irritations, persistent and unexplainable headaches, and mental confusion, often described as 'brain fog.' It's important to remember that mold can cause health problems even if it's not visible, as it can grow inside walls. If you are experiencing these unexplained symptoms, you may want to consider a professional mold inspection.

Mold doesn’t take long to form, especially in dark, isolated areas like under the floorboards, where you’re less likely to know it’s wet in the first place. Mold can take root and proliferate in just 24 to 48 hours, but it can be up to a week before you start to notice funky smells. 

Many types of mold spores and fungi spores are constantly present in the air, but they need a friendly surface and moisture to grow. Should some of these spores land on paper or wood with significant moisture present—such as drywall with a paper cover that is soaking up water from a leak—mold or fungi could begin growing. Dampness from leaky pipes, condensation on windows, leaks in a roof, flooding in a basement, or high, prolonged humidity in a small area all can create the excess moisture that mold and fungi need to grow in your home.
