"I had the foam insulation put in my attic and I am very pleased. The results were better than I thought. The attic was reading around 140 degrees and now it is 92 at the hottest part of the day."

"Price was about average, can't complain - don't remember exactly how much or exact service date (disclaimer).  Company screwed up the scheduling.  Installer was busy with personal life and we had to work around their schedule.  Inconvenient.  Came out and sprayed insulation in the garage.  They left the door open to the basement so the entire chemical smell inundated the basement.  The spray was general even but there seemed to be small holes and spaces generally through out the insulation.  When I inquired about the small spaces the response was they generally use the small spray cans you can get at Home Depot\Lowes but that they didn't have any.  I said I would take care of it myself, I had enough inconvenience with the screw up in scheduling.  Other than that went well - it's not that involved, just spray foam. 
They did clean up the mess relatively well, but not perfect."

"They were able to point out several issues with the existing crawlspace that we were not aware of. One A/C vent was completely off of the floor vent and just blowing air into the crawlspace.  There was missing insulation in places that needed to be replaced.  They found a damaged sill at the rear kitchen door that we were aware of and the main reason for why we called them.  They noted that the vapor barrier was not correctly installed.  They also noticed some foundation damage. The "C" rating for pricing was not for the inspection service that was on special for $50, that was an excellent price but the amount quoted to repair the other items I thought was average."

"l  spoke with three other solar installation companies and was unhappy with the level of professionalism and the knowledge of the salesperson. I had decided to cancel the idea when I came across Sunpro in an ad. I was attended to immediately, a very impressive assessment was done to analyze the amount of electricity I have been using through the years and exactly how many solar panels I would need to cover my power needs without overpaying for panels that were not needed.
Everything was documented for me in a very professionally done color booklet with all the facts, figures, and graphs that made it very easy for me to understand the entire process, costs, benefits, and etc. During this process I was advised what Government rebates were available for the installation of solar panels AND that if a structure was needed to mount the panels to, rebates might also apply to the cost of the structure. We had been considering adding a patio to our home and Sunpro showed us the benefit of building the patio now which would provide the exact location and angle for the panels to capture the maximum amount of sunlight.
The entire job was done in a surprisingly short time and the quality was superb. The patio (including stamped and colored concrete) turned out beautifully. Frankly, I don't think I have ever been truly satisfied with any work that has been done on my home until this experience. Even the city inspector remarked at the excellent quality of the work that was being done.
In addition, the Sunpro system included making the entire house energy efficient by spraying foam insulation in the attic and sealing the entire house. This extra step (which was never suggested by the other companies) has made an amazing difference in the way the home feels and it allowed for fewer panels needed to provide the power my family requires (saving me money).  I have found out since the installation that Sunpro used certain components in their system that were far superior to what the other companies had advised. These small and inexpensive upgrades have made this system far more efficient than what I had been shown by the other companies.
The owner of Sunpro provided amazing supervision for the entire job. Sunpro also provided ALL the documentation I needed to apply for the rebates and tax credits. Everything was put in an organized folder to give to my CPA. The entire process went perfectly. Since then, Sunpro has done other work for me that has also been done perfectly. I don't know if solar panels are right for everyone, but this is definitely one of the best decisions I have ever made. since the installation, I have not pain an electric bill. In fact, at this time the electric company owes me electricity.
I might add that in my particular case, the entire project costs LESS than what it would have cost me to build the patio alone.
Frankly, it is my policy to NEVER recommend anyone. I have taken the time to write this extensive recommendation only because I am 100% satisfied with the way the job was handled and the quality of the work and materials and the outcome of the entire project.

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

Drywall Insulation questions, answered by experts

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.

In some minor cases, you can DIY drywall repair with minimal time and money spent. This method is best when you have a hole made by a singular problem, such as accidental furniture moving, and not a continuous problem, like a rodent infestation. 

Knowing what product to use is crucial. For example, small holes only need spackle, whereas large holes might need a new piece of drywall. You can flex your DIY abilities on this project, but if you’d like a second opinion or have a more significant problem, it’s best to call in a drywall repair pro.

Plastering and skimming are two different techniques for finishing walls. Plastering involves applying a thick layer of a plaster mixture—typically containing gypsum, lime, cement, sand, and water—to create a new surface. This process often requires multiple coats and is used for repairing significant damage or creating decorative textures. Skimming, on the other hand, is a technique that involves applying a thin layer of drywall compound or joint compound over an existing surface to smooth it out, covering minor imperfections, small cracks, or uneven textures for a polished look. Plastering is generally more costly and labor-intensive than skimming. Although some people use the terms interchangeably, they refer to different processes and materials.

This depends on how much plaster is applied and in how many layers, but a decent estimate is around 150 square feet. If you are applying only two coats on a small wall, there is a chance you may only need one or two gallons for the entire project. If you are plastering a large living room wall with high ceilings, using one of the more involved techniques–like Scagliola–that requires several coats, expect the project materials costs to add up quickly. 

Applying plaster to a wall will usually cost between $2 and $10 per square foot for both the material and labor. The cost will vary based on the quality of the plaster you’re using and whether or not prep work is required before the work begins. Wall prep can add up to about 10% to your total costs. Plastering exterior walls can be more expensive in many cases because they are taller and require scaffolding and safety equipment.
