"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."

"Fantastic work! They had an old 3100 sqft roof stripped, repaired, and re-shingled in four days, at a low price. Fast, affordable, quality work. Had to take a 1/2 star off for cleanup... debris was left on one side of the house...but otherwise phenomenal job overall! I would highly recommend Lawless General Contracting! UPDATE - Four months later, with the first storm of the season, and the NEW ROOF LEAKS! It leaks worse than it did before Lawless replaced it. I have tried contacting them three times by phone and once via email and they are not responding. UPDATE 2 - 10 days after the first call, Dan from Lawless finally contacted me. Within a week he was on our roof, identified the problem, and had his team out to fix the issue. Dan has renewed my confidence in Lawless Contracting"

Drywall Insulation FAQs, answered by experts

Drywall insulation costs around $1,800, on average, but prices can range from $500 to $4,500, depending on a few different factors. The following things are important considerations to make when pricing out your insulation project:

  • Square footage of insulation

  • Type of insulation 

  • Climate in your area and the insulation R-value required

  • Whether or not your walls are already finished

  • Accessibility of the area 

  • Whether or not you need old insulation removed first

You’ll get better results if you soundproof the whole wall. A hole through which light can pass can also let sound waves in. Acoustical or silicone sealant applied to holes and cracks can block enough sound to make a difference. However, the more layers absorb vibrations and slow or stop sound waves, the less noise you’ll have. 

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.

On average, drywall installation costs around $2,000, with a typical range of $400 to $6,000, including materials and labor. The final price depends on several factors. The most significant is the size of the area, as many contractors charge per square foot. Other cost factors include the complexity of the job (e.g., cutting around multiple windows and doors, corners, or curved walls), accessibility, location, the thickness of the drywall, the height of the room, and the desired level of finish. The level of finish can range from simply hanging the drywall to taping and mudding the seams and painting the walls.

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.
