"From initial contact with their sales department we've had a great experience, Corey did an excellent job of taking pictures and showing the problems in our attic. Their level of communication from emails to phone calls was precisely correct by contacting me when needed and not too much with pictures detailing each solution and its associated cost. On the first work day their crew called ahead of time, arrived promptly and came prepared with masks, plastic sheeting, full body outfits and cloth covering for the stairs. In just over 6 hours they had cleaned up the entire attic removing bad sub-floor and other insulation, laid out the foundation for building a large deck space and placed part of the first layer of materials down. They also sealed the attic door along with some of the air vents and ceiling fans. They completed insulating my front porch overhang and cleaned up all of their mess very well. Painters tape was used on corners where they we’re most likely to bump into it for protection and plastic sheeting was setup precisely where needed to keep dust off of our hallway things next to the attic entrance. Overall it was a great first day and they even spotted an issue from a previous vendor who failed to properly connect some of their duct work together (which was the original cause of my daughter’s room temperature being so hard to control the temperature and not easy to spot). The only complaint I have is that while I fully expected the need to finish our attic sub-floor, remaining layers of TruSoftTM Cellulose on the main floor and encapsulate the duct lines with Polyurethane Spray Foam all before finishing with blown-in insulation, they left a key piece incomplete. When leaving they left the duct work leading from our main trunk line to my daughter’s room off. This left a hole in the main trunk line reducing heat in all upstairs rooms but most important is that nothing was connected to my daughter’s room. So around 6:00am she woke up coughing as we noticed the upstairs was around 56 degrees. Overall a simple heads up would have solved everything as we have space heaters, however I did not look into the attic when they left so that’s my fault for not knowing a key piece of the duct line was missing. Based on the overall work complete I would still very much recommend them as Robert (onsite team lead) was very good at communicating and the crew we’re all quite friendly. Their work will last for the lifetime of my house and has already added value to the sale price. In the end they made a really nice attic deck leaving me with plenty of useable storage space. While this is not the cheapest company, the quality and knowledge that I never need to worry about my attic again is certainly worth it."

"The company did a good job replacing old insulation in our attic. There was a communication hick-up but the project manager we worked with - Jamie - was able to correct and resolve the issue."

"After my call to Discount Energy Services, I knew who was coming and when to evaluate my attic insulation. The estimate was prepared on-site with pricing. The workers arrived and knew exactly what they were to accomplish, which they confirmed with me. They prepared the entire path with clean drop cloths and created a plastic drape around my attic stairs. The foreman was glad to explain any aspect of the procedure. My attic was upgraded to R-49 and the difference is notable."

"After researching and obtaining quotes from a number of companies, I selected The Fifth Fuel to air seal and insulate my attic (blown-in cellulose), cantilevers, and rim-joist. From the initial consultation with Adam to email follow-up, the project and my options were clearly explained. When I asked about putting a higher R-value in my attic, Adam provided the price but explained why it didn't make sense for me. I appreciated that he didn't try to oversell me. The proposal laid out everything they would be doing. The cost was reasonable. It wasn't the lowest bid, but was less than 50% of some other bids. The day of installation, the crew arrived a bit early. Throughout the install they were professional, kind, and clean. They protected the inside and outside of our house and vacuumed afterward. They conducted a blower door test at the end to quantify the difference made by air sealing. Within two hours of them leaving, we've already noticed a difference in our comfort and our A/C is not even running half the time it was before."

"They wanted to inject very expensive sealant into the ducts to seal the seams. The company I hired used insulating tape over the seams instead, for a greatly reduced price. The total price difference in their proposal and the company that I hired was about $4500."

"This guy called promptly to schedule an in home consultation and came promptly the next morning. I received a courtesy call from him saying that he was running 10 minutes behind schedule. When he got here, he was friendly, he evaluated my attic and determined that no insulation was needed. I tried to push him a little to say that we might need a little more insulation up there since that particular room gets colder than others but he insisted that adding insulation wouldn't help. I think others might have tried to get some work out of the visit, but not these guys. I would recommend them based on their honesty, fairness, and integrity."

Drywall Insulation FAQs, answered by experts

Wet-sanding and dry-sanding each have pros and cons. Dry-sanding is less messy, so it’s a good option if you’re trying to minimize dust (for example, if you’re sanding an occupied home or working with particularly dry or dusty drywall mud). However, dry-sanding is quicker because you don’t have to keep rinsing a sponge or wait for it to dry before painting.

It doesn’t matter which way you lay drywall, and you can choose to install it horizontally or vertically depending on the size of the wall and how tall the ceiling is. It’s easier to lay drywall sheets vertically if you have a taller ceiling, but laying sheets horizontally makes it easier to apply joint compound.

If you suspect black mold is inside your walls, do not punch a hole in the drywall yourself to look. Call a mold inspection expert to help you. Some signs of a potential black mold infestation inside the wall include an unexplained musty, damp smell. Some people liken it to rotting vegetables. You may smell it most strongly through a wall outlet. If you and your family are experiencing constant coughing or symptoms that feel like an unexplained allergy, it could indicate black mold behind a wall.

Professionals mount TVs using specialized tools and knowledge of different wall materials, ensuring safe support.

Yes, you can use drywall repair techniques for some types of plaster damage. Tiny holes and small cracks in plaster can be patched in similar ways to drywall. You apply the necessary compound to fill the hole, wait for it to dry, then sand it down. For larger damage, like water damage or mold, you need to use plaster-specific techniques and materials.
