Blown insulation, attics, walls, floors. Existing, remodel, or new construction. Fiberglass or cellulose
"Omar was referred to me by a relative. I called him and he said he would come look at the job. I explained to him that I wanted the roll insulation and not the blown in because I wanted the AC repairman to be able to still walk in the attic and see where the joists were when walking. I told Omar that I wanted the insulation between the ceiling joist. He agreed. When he arrived to do the job, he just laid the insulation on top of the joists covering them all as would have been with blown insulation. I told him that is not what we had agreed on and he said he had another job to go to but he would return later in the week to correct the problem. he requested payment and I paid him trusting him that he would return as promise. He told me he would email me a receipt and papers for a CPS rebate. Well he never did return or email me anything!!! I called him so many times that I lost count. I left him messages and he never returned my calls. I texted, emailed him and no luck. He did the work on February 2020) and to his date I have not heard from him. I am very surprised that Angie's list has him on their list!!! I would never refer him to anyone!!! BEWARE!!!!"

I install and repair garage doors and openers. I have been doing this for 7 years and I always make sure my customers are happy with my work. And I like helping each and every one of my customers to get the best deal possible
"They responded quickly when I contacted them. The price was fair, the work was good and done quickly, and they acted with integrity. I accidentally wrote them a check for about $300 more than what they quoted me. I never would have noticed, but he immediately brought it to my attention that I was overpaying him. Great company with good people that I highly recommend!"

"We have had the best experience with the team at CoolMark and the owner himself, Mark Garza. They have gone over and above to help us out when our AC unit died, and even after the installation to ensure everything is working correctly. I felt bad bugging them when our new unit wasn't working right but they kept coming out until they discovered the problem, even coming out twice in the same day! Their services and the product they install were very competitive price wise and they worked with us to get the best financing options. I would highly recommend Coolmark Heating and Air to anyone needing service on their current unit or installing a new unit all together. You won't be disappointed!"

"Power Home Remodeling started out by soliciting at my elderly mother's home even though she has a NO SOLICITING sign posted at her front door. They tried to sell her more than $20,000 of unneeded repairs using high pressure sales tactics. She opted for the almost $4,000 OVERPRICED gutters (her home is less than 800 square feet). When we tried to call them to cancel and to share about concerns they do not answer any of their 8 phone lines. Well actually, they do answer one line - the one for free estimates where they can come to your home and use aggressive sales tactics. I sat on the phone on hold all morning and never got through. Power Home Remodeling should be ashamed for being predatory towards senior citizens and using aggressive sales tactics."

FAQs for insulation service projects in San Antonio, TX
When choosing a professional insulation installer, consider asking these questions to determine the best fit.
Will you address air leaks in my house?
Can you provide an R-value (heat resistance) fact sheet?
What kind of insulation will work best for my home?
How do you handle signs of a water leak?
Are you licensed and insured?
Can you provide customer references?
The best type of insulation for your home depends on what you need, so the answer will depend on your specific situation. If you’re building a house, structural panels are easy to install during the building process in addition to being the most energy efficient type. If you live in a warm climate, reflective insulation may benefit you more as it costs less than other insulation types. And for standard attics, loose-fill, spray foam, or blown-in insulation work well.
If you plan to heat or cool your garage, you’ll need to insulate the garage ceiling. Insulating your garage ceiling will make your garage much more energy efficient and save on heating and cooling costs. Not only does insulation make your garage more energy efficient, it helps reduce noise and can extend the life of your garage roof. You can use fiberglass, cellulose, mineral wool, or spray foam insulation for this project.
In some cases, you may not have enough insulation to properly regulate your home’s temperature. Watch for a few signs your home needs more insulation, such as:
High heating and cooling bills
Uncomfortable room temperatures
Ice dams on the edge of your roof
Roof leaks
Cold floors and walls
Freezing pipes
Temperature fluctuations
Visibly low insulation
Noise problems
Pest problems
On average, insulating an attic costs about $2,500, ranging from $1,500 to $3,500, depending on the insulation type, amount, and your attic’s accessibility. Additional cost factors include sealing air leaks, removal or replacement of insulation, and inspections. Types of insulation include:
Blown-in: $1–$4 per square foot
Spray foam: $2–$5 per square foot
Batt: $2–$4 per square foot
Structural insulated panels: $4–$7 per square foot
Loose-fill: $2–$5 per square foot
Reflective: $0.50–$1.50 per square foot
