"Cny insulation came to my facility and our attic had very little insulation. They put blown in insulation, cellulose, along with fixing a bathroom vent, and a ventilation pipe. The before and after pictures showed over 15" of cellulose. They left the premises (church) immaculate. I would recommend to anyone. What a great job!"

"Had the underside of my cabin sprayed with foam insulation. I couldn't be happier. The floors were MUCH warmer this past winter. As a couple unexpected bonuses, the floors were much quieter, no creaking and the overall warmth of the cabin was NOTICEABLY warmer.. work was completed sooner than expected at a reasonable price! Thank you! Mike S."

"Scott arrived punctually for our first meeting and thoughtfully and thoroughly analyzed our problem (mold on peak of cathedral ceiling).  He listened carefully to our thoughts and explained his analysis clearly and completely.  He provided us with examples of similar situations he had addressed, successfully, in the past. He also showed us photos of his previous work. He spent over an hour with us, answering all questions and outlining his processes.  

After we agreed to have him do the job, he provided an extensive written contract for the work.  Our lawyer reviewed the contract and made several suggestions.  Scott quickly adjusted the contract to address our lawyer's concerns.  He scheduled the work promptly and it was completed in the agreed upon time frame.  We asked for the new electrical circuit to be labelled, and Scott took care of this without additional reminders, although I don't believe this was part of his usual service. There were no add ons to the bill.

After the work, Scott responded to questions and promised referrals to mold remediation services if required.  We've called him several times with questions, and he has always responded promptly with useful answers.

We have been totally satisfied with Scott Knapp and Rfactor from start to finish and would recommend him enthusiastically and without reservation to anyone with a similar problem."

Drywall Insulation questions, answered by experts

Costs range from $500 to $5,000, depending on damage size, labor, and finishing requirements.

Venetian plaster is a highly durable wall finish that becomes a rock-like substance once dried, making it last longer than most other wall finishes. Its lifespan can range from decades to centuries, potentially lasting a lifetime. Key factors influencing its longevity include the quality of the initial application, whether it's properly sealed against moisture, and how the wall is maintained and treated (e.g., how often it is touched or bumped). Due to its mineral content, it can also develop a patina over time.

Many homeowners choose to install tongue and groove over drywall. The great thing about this type of ceiling is that it hides imperfections. If your drywall is a little bit wonky or has some minor damage, the tongue and groove planks should cover it and give it an even appearance. Installation is simplest if you install battens over the existing framing before installing your tongue and groove planks.

Options include bricks, natural stone, and concrete blocks. Choose based on durability, aesthetics, and budget.

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.
