Affordable Insulation is a full service insulation contracting company for existing homeowners to find ways to improve the effectiveness in reducing home energy consumption. We specialize in drill-n-fill to exterior walls where no insulation exists, re-insulation of attics to increase R-value and garage door insulation kits.

"Used Affordable Insulation to blow in fiberglass insulation into attic above 3 car garage. They were quick to reply to my initial inquiry and follow up questions. Marc had the estimate to me the same day I contacted them. Their estimate was much more affordable (pun intended!) than another quote I received. I was very pleased with their number and was ready to hire them. The team of Jason, Jason, and Daniel were courteous, friendly and professional. They called ahead and showed up as scheduled. They made quick work of the job. The job came out looking great. Insulation depth was a couple inches deeper than expected so was pleased about that as well. They ensured no insulation was in the overflow drain pans of water heater or AC since that could clog the overflow drains causing them to backup. They cleaned up all excess insulation that had fallen into the garage. Attention to detail was superb. I highly recommend Affordable Insulation."

Protecting homes and businesses since 1950, Guardian Protection is one of the nation's largest and most highly regarded security companies. We provide smart technology, 24/7 professional monitoring, and peace of mind to hundreds of thousands of customers. Our products are installed by experts, monitored by real people, and truly make a difference. We do what we do because of one simple truth: life is better when it's safe.

"We hired Guardian to install our security system at our Washington, DC, business. The service and quality of the work was horrible. We had cameras and an alarm system installed; it was a relatively large system. They outsource most of the work to various vendors. They could not manage their vendors; what was supposed to take a week took two months. The sales rep did not return calls, and you could never get anyone in management on the phone. Random people would show up at unannounced times. The few things that an actual Guardian employee did were they made a huge mess of our newly remodeled office and were rude to our staff. We have offices in five markets across the US and have high security at each; we have never had such a poor experience."

John started in the drywall business in 1978. He is an Austin native and works on each and every job. He has an experienced crew to assist with larger jobs. He has been rated Top Drywaller in Austin for many years. Please text him at 512-789-0937 with your home address and type of work needed and he will call you back to discuss and set appointment.

"I am extremely happy with my experience with John and his company. A section of my garage ceiling fell and needed to be replaced. John outbid every other contractor with a fair price. He was professional, responding to ever call/text, and he confirmed day and time he would come to my house to complete the work. John and his team showed up promptly to do the work. It was amazing to watch how seamlessly he and his team worked. His experience and professionalism truly show, and there is no doubt he does his best work and takes pride in a job well done. At one point I told him not to worry about how pretty something looked because after all, it's a garage and it was an area in the corner. He said that if something is going to be done, it should be done correctly and done right the first time it's done. I should add that not only was the sheetrock replaced, but the length of the ceiling that was replaced was reinforced with 2 x 4 pieces of wood. That section of the ceiling definitely is NOT falling down any time soon. When all the work was done, they cleaned up and hauled away all the old material. You can't tell anything happened in the garage because of how clean they work. I highly recommend this company and would rehire in a heartbeat if any other drywall projects need to be done."

Insulation questions, answered by experts

Although the cost might seem high, winterizing your home is important for your health and the structural integrity of your home. Winterizing will keep your home warm and toasty during the cold months and prolong the life of your appliances, windows, pipes, sprinkler system, pool, and more. 

Most projects take 1-3 days, depending on area size and insulation type.

Expect your home insulation project to take between five and 12 hours to complete on average for batts or boards and two to five hours for spray foam or blown-in insulation. It might take longer if you need to remove your home’s existing insulation, you have a higher-than-average square footage, or accessibility is limited.

Fiberglass is the best insulation for HVAC ducting because it's inexpensive, widely available, versatile, and long-lasting. Fiberglass also offers acoustic insulation in addition to thermal insulation, which can contribute to a more peaceful home environment. You can use other materials like mineral wool, but fiberglass is the industry standard.

The most obvious con of injection foam is the cost. It’s much more expensive to install than fiberglass or spray foam, but it may be your only option (unless you want to remove entire walls around the home). Another con is that it involves drilling into existing material, which has to be repaired after the foam is injected. Some injection foams are made from products that aren’t environmentally friendly, and improper installation can lead to trapped moisture, which can lead to expensive mold remediation down the road.
