Were a locally owned and operated company that values honesty and integrity and treats your home or business as if it were our own. We are experts in all aspects of roofing projects and our services are customizable to each individual project. We specialize in both installations and replacements. We pride ourselves on the quality of our work as well as our commitment to outstanding results. We look forward to building lasting relationships and guarantee your satisfaction!
"On a scale of 1-10, we give this company an 11, based on the outstanding results they delivered. This was an incredibly challenging project. We have a very steeply pitched metal roof on a two-story home with skylights and a turret. We hired M&H to remove many years of mold off our roof, clear and clean all the rain gutters and reseal our skylights. They responded very quickly to my bid request, and within the same day performed a physical onsite roof inspection, rather than just generating an estimate based on a Google Earth photo like so many of their competitors. We are seniors on a fixed income and this is a major expense for us. We solicited quotes from several reputable and highly rated roof cleaning companies. M&H provided us with an extremely competitive bid. Avi committed to a firm, fixed price upfront. All the other bids I received were subject to additional charges during the cleaning, Excellent results. Highly recommend."

"Very satisfied with the whole process. Gerald did an excellent job. Arrived punctually and observed COVID protocols. Explained clearly what he was going to do and how. Showed us preliminary findings, and obtained our permission to take samples for lab testing. We felt he listened to, and responded to, our concerns. Overall a very professional experience.

"Exceptionally knowledgeable professionals with a service mindset. My office and storage building was flooded from a burst pipe last winter (2021/2022). I called up Affordable Restoration and they helped me through the whole process. They also referred me to a fantastic public adjuster who took care of the whole claim for me. I was impressed on how knowledgeable the Affordable Restoration crew was on not only the flood aspect but also on how to work best with my insurance company. They took the time to educate me throughout the whole process on water, mold, mitigation, restoration and the claim process. After my initial meeting with them, I felt like I was an expert on these topics. This gave me a lot of confidence in working with my insurance claim. It was a breath of fresh air to deal with a contractor that actually cares about you and takes the time to listen and address all of your concerns. Their crews did a great job. They always showed up on time, constantly monitored the site conditions and left the site cleaner than they found it. I'm confident that my building was restored properly and is safe for future use. I would highly recommend working with them."

Mold & toxic material tests FAQs
Some companies offer a no‑cost phone or video consultation that screens for red flags. If the discussion points to a real issue, the pro will recommend a paid on‑site inspection. The complimentary call clarifies whether you need full testing, but it isn’t a substitute for samples, lab work, or a written report. Always confirm what the free service covers before you schedule.
A standard inspection, which includes basic air and surface samples, takes an average of two hours. If the pro needs to probe hidden spaces, such as wall cavities or ductwork, plan on up to six hours. Extra time allows the inspector to reach tight areas, collect additional samples, and document findings. Lab analysis is a separate process and often adds several business days to the overall timeframe before you receive the full report.
Mold thrives where moisture lingers and air flow is poor. Common hotspots include bathroom walls, kitchen backsplashes, window sills, HVAC vents, fireplaces, crawl spaces, and enclosed attics. Check these areas regularly—especially after leaks or high‑humidity weather—to catch growth early and avoid costly repairs.
Unchecked mold can knock 20% to 37% off a home’s market value because buyers worry about hidden damage and health risks. Even after remediation, visible staining or a history of major moisture issues can still lower offers and prolong the time on the market. Addressing mold quickly protects both your property’s structural integrity and its resale appeal.
