"He came right away to assess the mold in the basement of a house we were working on. Provided alot of education on mold remediation and how he would treat the mold. He was very accommodating with his availability. We were unable to complete the project due to changes in family circumstances. Would recommend."

"Mike and his team did a solid job for us.  The previous owners had punted on installing
the correct solution and lied about water entering the home.  When we found ¼ inch of water in our back
room basement we called GMBS out and they were there within hours to do an
estimate.
This was one of the rainiest summers in recent memory and
GMBS had a ton of business so we had to wait, but it was worth the wait.  They finished the job in under 3 days and the
work looks great.
They installed a brand new sump pump, the old one the previous owners had
installed was done poorly, was inefficient to the task and sounded like a jet
engine.   They installed a sub floor
perimeter drainage system and vapor sealed our walls.
 
They were quick, professional, courteous and were easy to
work with.  We paid up front and part of
the job was over estimated and they got a refund to us when we needed it. 
 
I have more work I need done in the future and I plan on
using Mike and his team.

"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."

"DG Building did an outstanding job adding our custom deck bar. The craftsmanship is excellent, and it fits the space perfectly while taking full advantage of our mountain view. They also reinforced the deck with additional supports underneath the bar, making it incredibly sturdy and giving us complete confidence that it’s safe for family and guests. They were professional, detail-oriented, and clearly take pride in doing the job right—not just making it look good, but making sure it’s built to last. We couldn’t be happier with the finished product and would absolutely recommend DG Building to anyone looking for quality work."

Mold Testing and Remediation FAQs, answered by experts

It is generally not safe to live in a house with smoke damage, as even minor damage can pose long-term health hazards and structural risks. While it might seem safe temporarily depending on the severity, you should relocate if there is major damage or visible soot. Smoke smells and residue contain dangerous particulates and chemical compounds, including carcinogens, that are hazardous to breathe and can cause respiratory issues. These signs of damage are not always visible but can have dangerous short-term and long-term effects on your health, belongings, and your home's structural materials. You should not stay in the house until a trained professional from a smoke remediation or restoration company has assessed the damage and determined it is safe to return. Your insurance company may cover the cost of alternative housing while the professional work is completed.

Wood stain is not considered toxic after it dries. The solvents in wood stain are what give off volatile organic compounds (VOCs), which are toxic, but these dissolve as the product dries, leaving behind a non-toxic product. When working with wood stain, you should always wear a respirator and rubber gloves to protect yourself, but once it dries fully, it’s not toxic, according to the manufacturer’s instructions.

Hiring a professional for mold and toxic material testing ensures precise identification of harmful substances within a home. Professionals utilize specialized equipment and techniques, providing accurate results that inform proper removal strategies, safeguarding occupant health.

Running an air conditioner with mold is not safe because it can spread harmful mold spores throughout your home. Exposure to these spores can trigger various health problems, including respiratory issues, allergies, coughing, wheezing, sneezing, itchy eyes, and a sore throat. It may also aggravate asthma in household members. Continued exposure can increase the risk of more serious illnesses like sinus infections, pneumonia, and bronchitis. If you suspect mold in your air conditioner, you should stop using the system until it has been properly cleaned to avoid health risks and further contamination.

If you need mold remediation, you’re probably looking at a bill of a couple thousand dollars or more. Sometimes, though, your homeowner’s insurance policy may cover some or all of the costs of the remediation. If the black mold forms because of a covered event, such as a storm that damages your roof, and causes leaking or flooding in the basement, it’s possible the policy also covers mold remediation. It never hurts to ask your insurance company if it will cover the cost of black mold remediation.
