"I RECENTLY HAD MY ATTIC INSULATION REPLACED BY MASTER ATTIC. ALEX CAME OUT RIGHT ON SCHEDULE AND GAVE ME A FAIR PRICE. ( I DID HAVE 4 OTHER ESTIMATES) THE CREW LEAD BY ROBERTO WAS AMAZING. THEY WERE VERY CONSIDERATE, CAREFUL IN MAKING SURE THE AREA WAS SEALED OFF AND WERE VERY CAREFUL OF MY PERSONAL BELONGINGS. THEY DID A GREAT JOB IN REMOVING OLD INSULATION , VACUUMING OUT THE ATTIC ,SPRAYED AREA AND SEALED ANY OPENINGS. BEFORE THEY BROUGHT IN NEW INSULATION, THEY ASKED ME IF I WISHED TO TO VIEW THE ATTIC AND I DID. I WAS AMAZED EVEN AT THIS POINT, HOW CLEANED EVERYTHING LOOKED . (THIS INSULATION HAD BEEN UP THERE FOR 70 YEARS) NEW INSULATION WAS INSTALLED AND IT LOOKS GREAT. THE CREWED CLEANED UP EVERYTHING , EVEN VACUUMED THE AREA IN THE ROOM. ALL BAGS OF OLD INSULATION WERE REMOVED PROMPTLY AND I WOULD HIGHLY RECOMMEND THEM TO ANYONE."

Our primary bedroom is above the garage and even though we have a newer home, you can feel cold air coming thru the floor.  It's the coldest room in the house by far.  Ed's team came in and placed foam insulation in the garage ceiling.  He gave us $100 off for Angies list discount which was nice.  They cleaned up well when done.  Now that it's warm out I can't grade the quality of the work until winter again because I won't know till then if its helping with the problem.  I will come back and update then.  We had been quoted over $6000 by another company to do the work so hopefully this works and comes in far cheaper.

"Larry Doyle was a joy to work with.  He was originally one of the dry wall professionals who had given me an estimate on the ceiling repair to submit with my claim to the washing machine manufacturer, and I had been impressed with him then.  I waited a while before actually getting the ceiling fixed, but had decided to use Larry from my experience with him in preparing the claim.  I'm glad I did. He was prompt, highly professional, and did an excellent job.  Also, his price was very reasonable.  Further, he returned my phone calls quickly and was always responsive.  I would certainly use him again.

"Person who visited was very polite and noted that what I purchased was likely not something that would meet my expectations.  I wanted an energy audit, how my systems could be improved in home, lighting, heating, insulation and air conditioners.  What I got was a list of things they could work on and the price to do that work.  The work list in no way was considered an energy audit, rather it was a punch list of things I could do based on their visual inspection.  I did not have a comparison of work and benefit/savings calculation.  There was no checklist of inefficiencies and how that translated into energy losses. For example, multiple hi hat lights in house, they spoke about boxing and insulating a few, less than 10, when I have almost 90 in house.  Overall I was disappointed, the tech who came said the offering needed to be better presented prior to start of work."

I bought a ranch house that has been closed for a while, allergy issues got worse when I run the A/C unit. l look around for a good price and availability. They were quite busy but they helped me on a Sunday, that was perfect for me. Costumer service excellent from start to end , Daniel was very efficient, moving around very quick but meticulously cleaning each vent. They used shoe covers and vacuum any residue. I can tell the difference now. Great  service, I will use their service again.

"I have a contract with them.  It took them quite a few times, but I think they finally fixed the problem that I had with my heating unit.  Everybody was polite and caring.  It took 5 or 6 visits for them to figure out what the problem was.  I think and hope so the issue is resolved.  My overall experience was very good.  The quality was okay."

"It went great. We had our system installed in 2011. It took two days and we haven't had water in our basement and crawlspace since. Right Way Waterproofing did what I thought could never be done. They follow up every year and clean and check our system. I couldn't be happier. It has been the best home investment I ever made."

"They were very nice and professional. The only thing I wasn’t thrilled with was that my son’s room was sort of a brighter green color and I found areas where they had missed the second coat. However, they came right back and fixed it. Overall, I thought that they did a fine job. We spent about $3400, but we had the entire interior of our house done. They did a very good job. I would recommend them. They were two brothers and they had some other guys that worked with them. One of the brothers had gone home to Argentina at one point and I wasn’t sure if he was coming back. If they are still around, I would definitely have them back."

Insulation questions, answered by experts

Whether plaster walls should be insulated depends on whether the walls are at particular risk of moisture problems. In many cases, you can insulate plaster walls, while in others, it's a poor decision because of the lack of a vapor barrier. Choose a reputable insulation contractor to help you decide if and how to proceed to increase your home's energy efficiency.

You should not put fiberglass insulation in basements, since fiberglass is known to trap mold and mold is more commonly grown and produced in basements. You should also avoid placing insulation near water heaters, oil burners, or other hot appliances. For more information about the best and worst places to install insulation, consider hiring an insulation professional.

When doing any type of project involving mold, it's important to wear the right protective gear. You'll want an N-95 or KN-95 mask to keep yourself from inhaling mold spores, which can be irritating or trigger an allergic reaction in people with weakened immune systems. You'll also want to wear protective eyewear and gloves to limit your contact with mold.

It’s technically possible to install loose-fill cellulose insulation without a blower, but it’s much more time-consuming, tedious, and dangerous. You’ll need to wear the proper protective coverings to handle the cellulose after it’s been doused in boric acid; use a shovel when you can to transport the material from the bag into the wall cavity.

That said, if you purchase cellulose materials at a home improvement store, ask if they rent out blowers for free or at a discounted rate. In many cases, if you buy the material from the store, they’ll rent out the blower at no extra cost.

On average, insulating an attic costs about $2,500, with a typical range of $1,500 to $3,500. The final price often depends on the attic's size, with costs generally falling between $1 to $3 per square foot. For example, insulating a 1,800-square-foot attic would likely cost between $1,800 and $5,400.

If the project involves removing old insulation, this can add an average of $900 to the total cost, bringing a full removal and reinsulation project to around $3,000.

Several factors influence the overall cost:

  • Insulation Type: Prices per square foot vary significantly by material.

  • Reflective: $0.50–$1.50

  • Blown-in: $1–$4

  • Batt: $2–$4

  • Loose-fill: $2–$5

  • Spray foam: $2–$5

  • Structural insulated panels (SIPs): $4–$7

  • Project Complexity: Factors like sealing air leaks, poor attic accessibility, and required inspections can add to the cost.

  • Removal Issues: The discovery of mold, asbestos, or pests during the removal of old insulation can substantially increase the price.
