Q: Is ceiling insulation worth it?

• <div><p>Adding insulation to ceilings is an excellent way to increase the energy efficiency of your home. If your home's layout is such that you need insulation in the ceilings rather than in the roof, it's likely that at least some insulation already exists in the space. However, each additional inch of insulation you can add boosts the R-value by between 2.2 and 4.2. </p></div>

Q: Are there sustainable insulation options for attics?

• <div><p>Yes, including recycled denim and cellulose from natural fibers.</p></div>

Q: Does an attic floor need a vapor barrier?

• <div><p>Vapor barriers in attics are a bit outdated and most areas no longer recommend them for attic spaces. For vented attics, the best method is usually to install drywall and cover it with latex paint before attaching insulation fiberglass, cellulose, or foam insulation. When renovating an attic to use as a living space, a contractor can guide you on the best way to cover insulation.</p></div>

Q: How long does it take to install a radiant barrier?

• <div><p>Professionals can install a radiant barrier in a day or two, but DIY installation will take several days. The time it takes to install a radiant barrier depends largely on the size of the space and the installation method. Larger homes can take a pro two to three days to finish the job. It&rsquo;s also quicker to lay foil over existing insulation. </p></div>

Our tub/shower conversion to walk in shower went great and we are pleased with the outcome. Our installer, Walter and Oscar, were professional, able to answer any questions and very easy to work with.

It was a great install. They kept everything very clean from laying tarps down on our floors, to picking up all scraps both inside and out. He was very friendly and our new shower is BEAUTIFUL! Definitely recommend Mad City!

There was a lot more that needed cleaning than originally thought with lots of junk needing to be thrown out. Although they didn't know that when they arrived they, without hesitation, agreed to the extra work with a smile. Very professional!

Wonderful experience! As my mom is aging getting into her tub/shower was getting harder for her so we converted it to a walk in shower. The salesman was very knowledgeable and understood moms needs. Paul was our installer and I can't say enough good things about him. He was so personable...

Great communication and prompt service. They did scuff up the newly painted baseboard in one room. I thought the price was too high for the size of the home and the amount of work. But overall, fairly satisfied and would recommend them to others, however, for me I would shop around a bit more...
