"The installation just happened today. We had great service from Tara, who came to the house to give us a quote about a month ago and also great service from Keith and his crew today. Everyone has been friendly, explained everything and answered all our questions, took the effort to save our fragile cedar siding and clean up after themselves. Sitting inside after they left I could feel the difference in audible outside noise, Can't wait to pay those lower heating bills. Thank you!"

"What we thought was going to be a simple repair to our exterior trim, turned out to be a way bigger job than we expected. When Sherron Brown pulled off the trim piece, he found water behind our siding and black rotting plywood. He and his crew explained everything and what would be needed to fix it, and rather than scheduling a new time to come out, fixed it all in one day. They did a great job, fixed everything correctly, and were super friendly while doing it. I would gladly hire them again."

"Crew called before arrival and made sure that I was ready for service.  Requested to have the driveway clear for the truck.  Service took 2 days to complete.  Alerted me that there would be dust overall due to drilling in drywall and insulation work.
Staff moved furniture away from the outside walls and covered all with plastic.  This included living room, bedroom and office furniture.  Some pieces were quite heavy.  
During estimate and prior to the start of work, I was informed that holes were to be cut into drywall.  Drywall repair would be needed and was not part of the estimate.  Crew explained the process for insulating the walls.  2-inch holes were neatly made and insulation was blown into wall space.  Holes were then neatly rough patched.  Drywall needs to be professionally finished. 
Staff checked the attic.  Several pieces of furniture and other belongings of the prior owner were stored in the attic.  Staff emptied all of the pieces and neatly stacked them in the garage.  Completed attic insulation on the 2nd day.  Notified me that due to the construction and location of the attic steps, suggested that I add a layer of wood to ensure better insulation.  
I would definitely recommend EnerSol.

Drywall Insulation FAQs, answered by experts

Costs depend on labor, material quality, wall preparation, and finishing requirements.

All plaster walls will crack over time due to normal house settling and expansion and contraction from temperature and moisture changes. Small, thin hairline cracks are generally not serious and are mostly a cosmetic issue. However, larger or more significant cracks can indicate structural problems.

Here's how to tell the difference:

  • Cosmetic Cracks: Cracks that are 0.5 cm (0.2 inches) or thinner are typically cosmetic.

  • Structural Cracks: Cracks wider than 0.5 cm, excessive or deep cracks, multiple cracks in the same area, or cracks that span around corners can signify a structural or foundation issue. Cracks along the joints where walls meet the ceiling also warrant attention.

For cracks wider than 0.5 cm, structural repair is needed. If a crack is 2.5 cm (1 inch) or wider, or if you notice any signs of a structural problem, it is best to contact a plaster repair professional to assess the damage.

The age of your home can clue you in to whether you have plaster or drywall ceilings. Homes built after the ‘70s are more likely to have drywall ceilings and walls, while older homes have plaster. You can also do the pushpin test: A pushpin will go into drywall, whereas it’s much harder to push one into a plaster wall. If you’re still unsure, ask a drywall professional to let you know which type of ceilings and walls you have.

Drywall can get wet and dry out without sustaining permanent damage, but only if the water damage is minor. If you have a small leak and are quick to correct the issue and set up blower fans and dehumidifiers, your drywall should dry out. If the leak is persistent, the drywall becomes totally waterlogged, or mold begins forming on the drywall, you should remove and replace it.

You should wait at least 24 hours for drywall mud to dry before sanding or applying another coat. However, the exact drying time depends on several factors, including the thickness of the application, room temperature, humidity, and the type of compound used. Thicker layers, or projects in high humidity, may require 48 hours or more. Lightweight compounds tend to dry faster than heavier, all-purpose ones. You'll know the mud is ready when it feels completely dry and firm to the touch and has changed to a consistent light color. Sanding too early can cause smudging or gouges, so patience is essential for a smooth finish.
