"Our first interaction with Atlas was with Shannon. As knowledgeable and personable as one could hope for. She clearly explained cost effective measures to better insulate our house. We opted for sealing and insulating our attic and weather stripping a number of doors. We were very pleased with the workmanship and the energy savings they produced. They also helped us get a PEPCO credit which reduced the overall cost of the job. A winner!"

"I contacted Atlas not because of high energy bills but because of noticeable summertime temperature differences between the first and second floors. My home is 32 years old and had never had the ducts cleaned and I suspected there was leakage from seams in the duct work. While the house was built to the then current (1988) code levels, the code is now more stringent. For example, my attic insulation was R30 where code is now R50. Atlas first performed an energy audit. Based upon that outcome, they recommended: (1) rerouting the bathroom exhaust fans through the roof, (2) additional insulation in the attic bringing it to R50. (3) closed cell foam sealing in the main and garage attics where appropriate, (4) cleaning the heating/cooling ducts and (5) using the AeroSeal product in the same ducts. I opted for all of these services. The work was spread over 3 occasions, each no more than 2 days duration with most completed in a single day. Their friendly work crews were very attentive to my property, made sure to put down drop cloths throughout the house and generally made certain everything was clean upon leaving. They kept me informed throughout every task and showed/explained what they had encountered. My ducts certainly did need cleaning, even though it’s always been a smoke free home environment and without pets. The benefits of this work have been fantastic. The AeroSeal process yielded a 98% reduction in duct leakage. I can tell very little temperature difference between the first and second floors now. I’m expecting more noticeable improvements during the winter months. I strongly without reservation recommend Atlas Home Energy Solutions."

"Debbie showed up on time and seemed knowledgable about insulation. However she had a hard time answering my questions because she was overly fixated on price. That's not necessarily a bad thing but it got in the way of me really understanding the answers. When the quote came in it was very resonable but when i emailed with a follow-up question concerning warranties, the lack of record on Angies List (despite being in biz for 100+ yrs) and a sub-contractor she was going to use for an exhaust ventilation, she wouldn't put some of the answers in writing until after I committed to using her company. After reviewing all of the quotes we received we finally decided to take a leap of faith because she seemed knowledgable and the quote was fair. i emailed saying we wanted to move forward and asked if i could i now get the informatoin i requested in writing. Unfortunately it's now been 5 days so we are moving in another direction. I bet the company does quality work but it won't be with us.

Drywall Insulation FAQs, answered by experts

To hide drywall edges, you need to properly apply drywall tape and multiple layers of joint compound. These materials hide the seams between drywall sheets and fill the holes from drywall screws, leaving behind a smooth, flat finish to paint over. Apply joint compound smoothly, and finish the job by sanding the walls to make sure you fully hide drywall edges and other imperfections.

You’ll want to inspect your plaster walls for signs of damage before painting. If you notice soft spots, deep cracks, bubbling, or areas where the plaster is crumbling or pulling away from the wall, it likely needs repair. While small hairline cracks are common and likely cosmetic, you should address larger issues before painting to ensure a quality, smooth finish.

There shouldn’t be any gaps between your walls and ceiling. These can be fixed with joint compound but that is only a fix, and it’s much better if your drywall fits correctly in the first place. Sometimes gaps can appear if your foundation shifts significantly but if this is the case, you have a much bigger problem than patching drywall.

Both plaster and drywall are durable wall finishes, but they differ significantly in installation, cost, performance, and aesthetics.

Installation & Cost: Drywall installation is faster and more affordable, typically costing $1.50 to $3 per square foot. It uses premade sheets, making it a more accessible DIY project. Plastering is a labor-intensive craft that requires specialized skills, pushing costs to $2 to $10 per square foot. It involves applying a wet paste over a lath framework.

Durability & Performance: Plaster is generally more durable, longer-lasting, and provides superior soundproofing. It is also a better insulator, which can help reduce energy costs. Drywall is easier to remove for future renovations.

Aesthetics: Drywall provides a smooth, uniform surface ready for paint or texture. Plaster offers a high-end, naturally textured look that can hide imperfections and is often preferred for achieving a classic or historic aesthetic.

Which is better? The choice depends on your priorities. Drywall is ideal for those prioritizing a lower upfront cost, faster installation, and DIY potential. Plaster is the better option for a higher-end project where durability, soundproofing, and a unique, premium finish are more important than the initial cost.

While not always necessary, you can glue a drywall ceiling in addition to using screws or nails. Drywall is typically secured to ceiling joists with fasteners, which is often sufficient. However, adding construction adhesive can offer benefits like preventing sagging, bridging gaps, and reducing air leaks for better energy efficiency. It may also be used for specific acoustic or insulation needs. On the other hand, many professionals advise against it because properly placed screws make the drywall structural, glue doesn't add strength, and it makes future repairs or replacements significantly more difficult. Ultimately, it's best to follow local building codes and project-specific requirements to decide if adhesive is right for your ceiling.
