"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

Rigid foam board insulation is one of the safest insulation materials for basement walls. The panels offer a moisture barrier to prevent mold and mildew build-up. At the same time, this material is also fire-resistant, so you don’t have to worry as much about a fire breaking out as you would with spray foam insulation. 

If you feel your energy bills are too high or your HVAC system is working harder than necessary to maintain the correct temperature in your home, you may have an under-insulated home. If you’re unsure, consider having your system’s efficiency assessed by a local independent energy auditor.

It’s technically possible to install loose-fill cellulose insulation without a blower, but it’s much more time-consuming, tedious, and dangerous. You’ll need to wear the proper protective coverings to handle the cellulose after it’s been doused in boric acid; use a shovel when you can to transport the material from the bag into the wall cavity.

That said, if you purchase cellulose materials at a home improvement store, ask if they rent out blowers for free or at a discounted rate. In many cases, if you buy the material from the store, they’ll rent out the blower at no extra cost.

Insulating under a concrete slab foundation is a great way to improve the energy efficiency of your home, but it isn't necessary for outdoor projects like driveways, patios, sidewalks, and walkways. If you’re pouring in cold weather, insulating under the slab can help prevent heat loss from the concrete, aiding in proper curing. Along with accelerants, this can be a good way to ensure strong concrete despite pouring in the cold.

Upgrading insulation offers several benefits, including improved energy efficiency, which leads to lower heating and cooling costs. It also enhances indoor comfort by regulating temperature and can provide noise reduction. Additionally, better insulation has a reduced environmental impact and can increase your home's value and overall livability.
