"I communicated with Ron directly and he was determined to solve our insulation problems. He had to remove drywall in our entranceway and add in insulation where there were large gaps and air was getting in. He had a worker drywall and patch up the wall. The drywall worker did an amazing job! 
Ron also fixed an ongoing issue we had in our garage ceiling that was causing our living room floor to be cold and drafty. He worked around our schedule and made multiple visits to our home to fix the issue. We are happy customers and happy to say that the problem is fixed. We were very pleased with Ron and his company and do recommend him highly.

"Had concrete sidewalk slabs leveled, was out of level about 3" to each other and twisted one sided, fantastic job was done, results better then expected. I would highly recommend this company for leveling jobs. I rated customer service lower because pre hire communication was lacking at times"

Insulation questions, answered by experts

In some cases, yes, insulating an unheated garage can lead to mold and mildew. The issue with insulating a garage is that the interior will warm up and cool down more slowly than the exterior air, which can cause condensation inside the space. Where there is moisture, there is likely to be mold and mildew over time. Installing a vapor barrier can help avoid moisture and mildew problems in an insulated garage.

Insulating ductwork improves your HVAC system's energy efficiency by protecting the air from external conditions and preventing energy loss as it travels through the ducts. This means your system doesn't have to work as hard to heat or cool your home, leading to lower energy bills and a reduced carbon footprint. Additionally, insulated ducts help maintain a more consistent and stable indoor temperature, enhancing comfort. Proper insulation also improves indoor air quality by reducing the entry of allergens and pollutants and helps prevent problems like condensation and mold formation within the ductwork.

Monolithic slabs don’t require insulation, but many homeowners choose to have their contractors install insulation under the slab during construction. This can help improve home efficiency even more and keep indoor temperatures more stable. Slab foundations are more energy-efficient than uninsulated crawl spaces and basements, and insulated slab foundations are more energy-efficient than insulated crawl spaces and basements.

Water freezes at 32 degrees Fahrenheit, but the actual temperature that can cause frozen pipes can vary. Generally, it takes 12 hours for pipes to freeze at 32 degrees Fahrenheit.

Uninsulated pipes can freeze if it’s 20 degrees Fahrenheit or colder for over three hours. If your pipes are insulated, it can take six hours or longer for pipes to freeze. Note that some pipe types freeze more often than PEX pipes. Copper pipes freeze more often because the copper conducts energy and loses heat quickly.

If you have bubble wrap lying around the house and you don’t care about the odd look, taping bubble wrap over a window is a very affordable way to insulate it. Another inexpensive option for insulating windows is to add new caulk around the glass. This step quickly cuts down on air drafts for older windows, and a tube of caulk only costs a few dollars. Adding plastic shrink film around the glass is another cost-effective option. You can purchase a kit of plastic film for a few dollars per window.
