"It went really well. Robert Carroll really knows his stuff. Hire this guy. I say that without reservation of any kind. Don't look any further, believe me, I did. This is the smartest guy. He is honest, dependable, offers fair pricing, and his team can do all the work. I got several estimates from A+ rated insulation companies, but Robert was more knowledgeable than the other companies. He was the only one to point out that my soffits were not vented. Apparently, my house was built on the day no one was inspecting. The builder never cut open the soffits. That meant there was zero airflow going through my attic. The attic fan could run all day, but without air to move, it would not do any good. Only Robert noticed this and offered a solution to fix the problem! I asked some of the other A+ companies if they would vent the soffits and they all said they don't do that work, but they would be happy to add more insulation, which would not fix the problem if the attic was not vented."

"My attic was poorly ventilated — damp, musty, and overdue for attention. After deciding to bring in a professional, Randy came out to my home, thoroughly assessed the problem areas, and put together a detailed quote on the spot. The scope of work included removal of the existing insulation, air sealing around all attic entry points, sanitizing, air baffle installation, and installation of new Weather Blanket cellulose insulation. The new cellulose achieves an R-value that meets or exceeds Illinois code requirements. I couldn't be happier with the results. I've already noticed a meaningful improvement in temperature consistency and overall comfort throughout my home. If you're looking for a trustworthy, professional insulation contractor, I wouldn't hesitate to recommend Paragon Insulation & Services."

"These guys came out right away, gave me a fair price and did the job great ! The toughest part was removing old insulation, getting it out of my house and cleaning it all up. They did all that and sealed up my basement tight ! Using their foam insulation they filled in all gaps. And they did it in one day ! We now notice our house stays a little warmer and no more mice ! Kyle and his crew were fantastic and I recommend them highly. -- Alan B - Sun Prairie"

"Thorough discussion of what is wanted or needed. No hard sell. Stayed connected and showed up on time with a large crew. We planned on installing a ceiling fan in the future and figured it would have to be done before the installation was done. Austin agreed and said if we bought the fan he would get someone it. We did and the ceiling fan was installed PERFECTLY the same day as the installation. Energy rebates were applied to billing. Also, you work directly with the owner at all phases."

"Dan did a great job showing me all of the ways my home was losing heat in the winter and then fixed the issues. Really nice guy, informative, hard working. Not only did he install lots of insulation he also sealed cracks, vented bathroom fans, sealed up an old kitchen fan, etc. He showed up as promised and completed the work in a very timely manner."

Eifs Installers FAQs, answered by experts

Finding a reputable contractor for an egress window installation involves researching and vetting potential candidates. Start by searching for local professionals, reading customer reviews, and checking their websites for a portfolio of their work.

Once you have a shortlist, ask the following questions to ensure they are qualified:

• Are you licensed and insured?

• What experience do you have installing egress windows?

• Can you provide references from previous customers?

• Do you perform the work yourself or use subcontractors?

• What is the estimated project timeline and your current schedule?

• How do you handle payment?

Yes, you can install a bay window in an existing house. You’ll need to have a structural engineer draw up plans to add the necessary support to your exterior load-bearing walls and a general contractor to make the changes to the framing around the new wall opening. This will cost an average of $3,000. After that work is done, a window installer can set the new bay window in place.

The proper way to install a window well is to measure the window, dig a hole deeper and wider than the window, place a drainage tube and cap, anchor the well to the foundation, caulk the seam, and backfill the hole. The job requires tools such as a hammer drill and auger and some heavy digging. Proper placement and window well installation are critical to preventing water from leaking into the window.

Yes, egress windows are grandfathered. However, this comes with some specifications. If you are remodeling a basement or adding a sleeping area, you’ll need to update the egress windows to be up to proper code. But, if you’re leaving your home as is, you do not have to adhere to these requirements.

Basements are generally required to have windows for your safety. At a minimum, windows should provide an egress in the event of a fire. But basement windows do more than offer a way out; basement windows also offer natural light and ventilation in an area of your home that is otherwise dark and musty.
