"Perfectly. Carl met with me for a challenging problem/project I had previously hired (years ago) another contractor to solve/install. It involved installing a natural stone “stairway,“ with landings, on two small hills. The previous contractor did not succeed. Carl assessed and knew instantly what needed to be done, gave me a reasonable price, communicated effectively, always showed up on time with his crew and, at the risk of sounding hyperbolic, did a perfect job. Every member of his crew was customer and project focused. I already plan to welcome them back for another project elsewhere on my property."

"Trenton Roofing is simply an amazing company from start to finish. 1.5 years ago I did a roofing project with them and Brian the technical sales rep did not do the typical U.S. sales approach by sitting together and putting pressure on you to make an immediate decision. He even did his measurements while I was absent and just sent me over a quote which I directly accepted and the work was again done while I was on vacation. Totally great job and everything was handled with car. At that time I also asked for an estimate for new gutters but I wanted to have them replaced AFTER the solar panels have been installed again and this year I wanted to get it done.I used the old quote, placed the order, got confirmed but - and now the best - within the 72 hours cancellation period I decided different and I just met Brian without any hard feeling from his side we cancelled the job and my down payment was immediately reimbursed! What an outstanding attitude!For my siding project the bid is your!"

Protecting homes and businesses since 1950, Guardian Protection is one of the nation's largest and most highly regarded security companies. We provide smart technology, 24/7 professional monitoring, and peace of mind to hundreds of thousands of customers. Our products are installed by experts, monitored by real people, and truly make a difference. We do what we do because of one simple truth: life is better when it's safe.

"We hired Guardian to install our security system at our Washington, DC, business. The service and quality of the work was horrible. We had cameras and an alarm system installed; it was a relatively large system. They outsource most of the work to various vendors. They could not manage their vendors; what was supposed to take a week took two months. The sales rep did not return calls, and you could never get anyone in management on the phone. Random people would show up at unannounced times. The few things that an actual Guardian employee did were they made a huge mess of our newly remodeled office and were rude to our staff. We have offices in five markets across the US and have high security at each; we have never had such a poor experience."

Insulation questions, answered by experts

Mineral wool has an excellent life expectancy of up to 50 years, provided it's kept dry and free of pests. Compared to fiberglass, with a life span of 20 to 30 years, mineral wool stacks up well for long-term cost savings. Sheep wool maintains a similar life span to fiberglass, while estimates for hemp wool insulation life expectancies are all over the board, ranging anywhere from 20 to 100 years.

Pipes in your house can freeze after six hours or so if you lose power and temperatures are below freezing. You can prepare for potential power outages by winterizing your pipes with insulation. Also, whenever temperatures drop below 20 degrees Fahrenheit, turn your faucets on very low and leave them dripping until temperatures rise.

The cost of installing spray foam insulation is $2,760 on average, but this cost can be as low as $650 or as high as $7,700. The main cost factor is the size of the insulated area and the type of spray foam insulation. 

Polyurethane spray foam costs between $0.44 and $1.50 per board foot, where a board foot is equal to the volume of a one-foot length of a board. More expensive options, like soybean or vegetable oil spray foam, range from $1.50 to $3.00 per board foot.

Upgrading insulation enhances energy efficiency, noise reduction, and indoor temperature regulation. It leads to cost savings on energy bills, improved home comfort, and reduced environmental impact, increasing home value and livability.

There are no building codes requiring HVAC duct insulation for ductwork in conditioned spaces, like walls or floors. Unfinished basements are also exempt from this requirement. However, many homeowners choose to insulate their home's ductwork in some or all of these areas to increase the system's efficiency and reduce potentially harmful areas of condensation.
