"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

With its breathability and flexibility, lime plaster is among the most durable of all plaster types. It's also fire-resistant and has a proven track record, as people have been using it for thousands of years.

However, all plaster types will last for many years with the right care and treatment. Proper preparation and installation will also help ensure your plaster walls look great for as long as possible.

Installing or repairing plaster on ceilings differs slightly from performing the same motions on a wall. You’ll apply slightly less plaster to lower the overall weight of the ceiling. Wall texturing is common, whereas most ceilings are smooth plaster. Tough coat plaster is strong, meaning you can use less while retaining a solid surface.

Yes, you can install drywall over plaster, but there are important factors to consider. While it can create a smooth, flat surface, it is often not the best approach. Installing drywall over plaster will increase the wall's thickness, which can cause issues with existing window and door frames that may no longer fit. You might also need to adjust power outlets to keep them accessible. A better, though more expensive, option is to remove the old plaster and lath entirely before installing new drywall. Drywalling directly over plaster seals in the old material, and if any problems arise later, you will need to remove both layers down to the structural beams for repairs. Given the potential complications, this job is best handled by professionals.

A common cause of separation between a wall and the ceiling is truss lift—this can happen to the ceiling of rooms directly under the attic when the seasons change and wood building materials dry out, shrink, and shift. Roof trusses often dry out at different speeds, and if the bottom pieces dry out faster than the top pieces, they can shrink and pull the attached drywall away from ceilings and walls, causing cracks. Fortunately, truss lift is only a cosmetic problem, not a structural problem, and you can fix it by separating the ceiling drywall from the roof trusses, and patching the cracks.

The short answer is yes, a sagging plaster ceiling is dangerous. Sagging plaster on a wall is something you should fix immediately, but it isn’t a major concern. If the same type of sagging occurs on a ceiling, however, you could be in danger of your ceiling falling in large chunks. When plaster sags, it loses its strength and ability to hold itself up. The bonds that hold it together are strong, though, so if a sagging area falls, it will take large pieces down with it.
