"Tim and Jeff were very fastidious in setting up, cleaning, and making sure the house was in good order when they left . We also had an Aeroseal treatment which followed with James and Connor. It did take some time to set up after the vents were cleaned and blown out, but the application of this polymer to close gaps in lthe galvinized steel ducts was remarkable."

"St. Louis Insulation did a great job with insulating and ventilating both the attic and basement of our 123-year-old house in STL city. Zac was very knowledgeable and helpful and the service was affordable. The job was done quickly and efficiently. I highly recommend them for any insulation needs in the city."

"First : I was concerned with the negative reviews .So i contacted them and asked for an explanation ..I was satisfied with what they had to say ..and I thought their honesty was refreshing 
My electric bills were 2 times more than my neighbors 
2) i scheduled a home assessment .. and even though we had a schedule change communictaion was always good 
3) after assessment they suggested $5000 plus in upgrades , but gave no pressure to use their service ..I researched the cost of DYI vs. using them and consulted with Ameren to advise ..I decided Peterson was about 25% more than doing the job myself and was satisfied that was worth not doing the job myself 
4) but I saved a little by doing the easiest job myself ...Insulating  my open basement rim joists 
5) The workers were quick /clean/courteous/and professional ...THEY CLEANED AFTER THEMSELVES !!!
6) Work was complete and I am 100% satisfied 
I have waited a few months to see if my energy costs went down (before reviewing) ... It is hard to accurately quantify savings ...but in comparison to neighbors it seems to have a 35-40% reduction in electric use during warmer months ...That said I would still have a few years to break even with  cost of insulation ...BUT the comfort level in our house was well worth the costs ..We used to have a warm upstairs and used a a/c window unit to keep up ..We no longer need window a/c and everyone is happier and house temps are more moderate on each level 
Final assessment : It was expensive but well worth it and Peterson was a very good provider of advise and services

"I’m a land lord of 72 residential properties and the biggest head ache other than common upkeep was the constant battle with roaches and insects inside the units, I had Triple B come out and put their pest control infused insulation at 10 of my properties and within 3 weeks the tenants were in shock at how affective it was, they went from seeing them everyday to hardly ever, I ended up getting them to do all my units and also my own house, this will be a must at any property I ever purchase, highly suggested for new home owners/buyers"

Drywall Insulation questions, answered by experts

Yes, you can apply new plaster over an existing plaster surface, such as a wall or ceiling, provided the old plaster is in good condition. Before you begin, check the stability of the existing plaster. The surface must be clean, free of loose material, and have no peeling paint. It is also recommended to roughen the surface slightly to promote adhesion. For older plaster, applying a base coat like a PVA emulsion or a specific bonding agent or primer is crucial. This step makes the existing plaster less porous and ensures the new and old layers adhere properly for a smooth, long-lasting finish.

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.

In framing, studs are placed at 16-inch intervals to coincide with the typical spacing of wall materials such as drywall or plywood. This spacing is called "on-center" and is necessary for maintaining structural stability and efficient use of materials. The 16-inch spacing also helps to distribute the weight evenly across the building's structure. For those looking to cut material costs and improve energy efficiency, 24-inch stud spacing can be employed through a method called "advanced framing". This requires careful planning and adherence to local building codes to ensure structural integrity.

If you don’t have studs in the area where you want to install your TV mount, you may still be able to install a TV mount on drywall. The easiest way to install a mount on drywall is by using drywall anchors—but not just any plastic anchors. Choose molly bolts or toggle anchors, which have a weight capacity of around 50 pounds. For added support, consider pairing drywall anchors with a wall mounting plate. Extra heavy TVs may need to be mounted via the ceiling joists or beams.

Brick and stucco are a lot more different. You must use picture hanging clips designed for brick walls, or use a plaster rail system with adjustable hooks. Any other type of hanging hardware will cause damage to the bricks behind. You won’t be able to really use nails, either, because they’re not strong enough to go into the bricks.
