"Our heater stopped functioning on Nov 27, 2023 and we called Petro who had done the maintenance on it before and replaced a motor two years ago. They were responsive and a technician came two days later. He worked for 3 hours without explaining what the problem was. Then said he needed to replace the motor. He fixed the problem and left without much explanation. Two days later a bill of $2500 came via email. No explanation, no break-down. I called 4 times over the last 20 days, spoke to 4 different reps and was promised that a supervisor will contact me with the bill details. Nothing happened. Irresponsible customer service and unprofessional behavior. They show all the symptoms of big, bureaucratic, and indifferent service company. I would not recommend Petro if you have options of more personalized services."

A full service Home Handyman. When needed, I will act in the capacity of a General Contractor employing licensed tradesmen (plumbing and electrical). I've been in business for 12 years serving the North Shore and Middlesex County locations with a customer list well in excess of 400 customers/homes I offer my services at a fixed hourly rate of $50.00/hour while on-site. Travel to/from the customer's location is $25.00/hour plus the cost of fuel. In many cases, customers need to know in advance, what a given project will cost and I provide a written estimate in advance of any work for the customer's review and approval prior to any work undertaken. I accept personal checks as a form of payment. With a background in Electrical Engineering, I tend to take an analytical approach to the work at hand, looking for the optimum solution to any given problem, and not always the "conventional fix". What I repair or build has to be functionall, durable and esthetically pleasing. It's got to "look right" as well as "work right".

Spray foam insulation services FAQs

Yes, you should remove old insulation if it's damaged, contaminated, or deteriorated. Signs like water damage, rodent droppings, mold, or gaps mean removal is essential to maintain energy efficiency and a safe living environment. If the insulation is intact and functioning well, removal isn't necessary. However, compromised insulation can increase energy costs and pose health risks.

Attic insulation lasts 80 to 100 years; however, its performance starts to decline after 15 years. Insulation loses effectiveness as materials like fiberglass become dirty, wet, or affected by mold and other contaminants. Regular evaluation is critical because reduced insulation performance leads to higher energy loss. A professional inspection confirms when replacement is necessary, ensuring that your home maintains peak energy efficiency and comfort.

Excess attic insulation does not enhance energy efficiency beyond an optimal threshold. When insulation surpasses the necessary level for your region’s climate, additional material does not improve heat retention and may cause moisture buildup. Maintaining the correct balance is essential because over-insulation can lead to unintended issues without lowering energy costs. A professional assessment ensures that the amount of insulation is ideal for performance and efficiency, and helps avoid unnecessary expenses.

R-value is the measure of a material’s ability to resist heat transfer and directly determines insulation performance. A higher R-value means the material retains heat efficiently during winter and minimizes energy loss in warmer months. Selecting insulation with the appropriate R-value for your specific location is essential because environmental conditions and installation areas significantly influence energy efficiency. Over time, external factors like moisture may degrade the R-value, which underscores the importance of periodic evaluation.

Insulation damage occurs in several forms, including mold growth, pest infestations, water intrusion, and electrical harm. Damaged insulation compromises heat retention and significantly increases energy expenses while posing serious health risks. Immediate removal and replacement of compromised insulation are imperative to restore optimal performance and ensure the safety of your home. Regular inspections will identify these issues early, allowing for swift corrective action that maintains efficiency and protects occupants.
