"WOW!!!! Professional, courteous! I had serious hail damage to my roof and Single Source came in, did the estimate, contacted my insurance company and within a few weeks, I have a fabulous looking new roof upgraded roof! Justin at Single Source is extremely knowledgable on building codes and because of that, he was able to show the codes to the insurance company to get the upgrades covered. Their roofing team worked from the moment they arrived with one short lunch break working almost 12 hours. They completed the entire job in one day and my roof is 2,000 square feet, so it's a sizable roof. The team was very careful to protect my gardens, they moved plants, lawn furniture and put everything back they in place before they left. The clean up was impeccable!

"INCOMPETENT AND UNETHICAL. Said roof was fine, no worries for some thirty years. Within weeks of moving in a leak into master bedroom ceiling from leak in rook. Evidence of previously repaired leak in bedroom ceiling. Three independent roofers said roof must be replaced. Warranty associated with company said they don't pay for roof replacement, only fix leaks, and required report with info on each leak. I explained that entire roof was defective and they stopped responding to calls and emails. Hank, CEO of Hompro, also would not respond to multiple calls and emails. I complained to realtor who said he would call. he made one perfunctory call and has not answered my return calls, including one where I left a four hour window when I was available to relieve call. CHECK BETTER BUSINESS BUREAU - SAME COMPLAINTS. Had I known about roof I would have negotiated home price accordingly. Now I am paying for new roof. BEWARE OF THIS COMPANY."

FAQs for toxicity and mold removal projects in Portsmouth, RI

Remediation should keep mold from returning as long as the moisture source is eliminated. Fix leaks, control humidity, and replace water-damaged materials, then schedule periodic inspections to stay ahead of new growth. With those safeguards, your home can stay mold-free for the long haul while protecting both health and property value.

Most pros recommend leaving the home while they work on mold remediation. Removing mold stirs up airborne spores that can aggravate respiratory issues, and contractors can work more efficiently in an empty space. A short, temporary relocation keeps everyone in your family safe and lets the crew finish the job without interruption.

Mold shouldn’t return once the moisture problem is fixed. Stay vigilant: repair leaks right away, keep humidity below 50 percent with a dehumidifier placed in damp areas, and improve ventilation where needed. Routine checks for leaks and mold and quick repairs go a long way toward keeping your home mold-free.

Mold spores can trigger nasal congestion, throat irritation, coughing, wheezing, eye irritation, or skin rashes. People with asthma, allergies, or weakened immune systems often feel the effects sooner and more intensely. Some molds also release mycotoxins linked to serious respiratory or neurological issues. Swift remediation and better ventilation are the best defenses.
