"Fantastic. Of all the home improvement companies who have worked on many different jobs at this house in six years, Madrona takes the cake for providing the best quality work and amazing customer service. Madrona was the only company who gave us a thorough plan to not only put insulation in the attic but also to improve ventilation and ensure all roof penetrations were properly sealed. They added 1300 ft of R-44 blown fiberglass insulation over existing rock wool insulation that was fine but inadequate, to bring it to R-49. They fashioned a new wood access panel to the attic with a huge covered batt of fiberglass insulation fastened on the upper side and it feels like opening a secure air lock on the rare occasions where we've looked up into the attic. After they sealed all air penetrations in the attic they were very happy to show us what they did before adding the insulation. They installed insulation shield around the chimney, six roof jacks for proper venting, and vented kitchen and bath fans to dampered roof jacks, insulated with R-11 fiberglass batts. Four years later, the attic looks fantastic - there is no sign of any moisture and the blown in insulation looks as fluffy and lofty as when it was newly installed. I mistakenly thought one of the bath vents had been filled with insulation foam, causing the fan to not work very well, and Madrona sent someone out the next day even though the job was completed four years ago. Curt investigated and then politely and patiently explained that the side vent had been replaced with a better roof vent. And indeed, the fan was blowing air through the roof vent they installed and it is the old fan that is the problem, not Madrona's work. It would be wonderful if all companies stood behind their work this way."

"If I can give a 10 star review I would. Not only did they beat the lowest asking price but was done in 3 days when others told me 4-7 days and on top of that left it spotless for the drywall guys. I recommend that you give them a shot, you won’t regret it. Company is based out of northern Wa but boy did they shock me coming 3 hours south. Thank you Nick and keep it up ??"

"Enrique and Alex performed the task. They were punctual, polite and very quiet, which I was very happy with. I expected the hose and insulation to have been noisy. Great job, thanks so much."

"I intended to insulate an one car garage and the attic of the whole house. They were prompt to provide an estimate and very professional and honest on suggesting best solution (ended up with not doing the attic for now). The job was completed fast and really happy with the result. The crew was friedly and respectfull. Kept the place clean after all the blow in insulation."

"I needed my attic insulation updated. It had the original “blown in” loose material from 1975. After 49 years it had deteriorated and compressed. It was only a few inches deep. Also a leak in our old roof (recently replaced) had caused some mold in the old insulation. It had to be removed completely and redone. I called JB Insulation and asked for an estimate. Jose came over and inspected our attic. His experience and expertise was evident by how he explained everything. I felt very confident that I wanted his company to do the job. His price was very competitive and offered us the most value for our money. On the day of the job, his guys took much care in preparing for the job. They covered and taped our floors and wall corners to protect our home’s interior. They used a high powered insulation vacuum and removed all of the old insulation. They installed the new insulation and new baffles all in one day. Our attic looks great and we are really happy with their work. Yes I would recommend JB Insulation."

"We had rat damage to our insulation and ducts in our crawl space. In addition the vapor barrier needed to be dealt with. He did a great job as this was a tough area to work in. We also had him clean our dryer duct as it also was under the house. He took it apart and brushed it clean. We were so happy with all his work that we had him clean all of our furnace ducts with his power brush and vacuum."

"They were great -- very punctual and professional. Nick, the technician, didn't hesitate to tell us in depth what he was thinking and why. He troubleshot the problem successfully, laid out our options and didn't try to up-sell us very h****** a new expensive furnace. I was very pleased with everything involved with this transaction.

"Excellent experience. Rafael from Golden Quality Builds was a very good communicator and ensured I knew the scope of work, timelines, and when his team would be on site since we were living here during the project. He was able to work with us within our budget and made sure the work was done to code so it would pass inspections. His team was knowledgeable and when we ran into issues related to the age and poor prior maintenance of the house he made sure I knew what my options were. The house looks great and is more comfortable to live in already. We feel confident the work will last for decades to come. I would definitely recommend Golden Quality Builds, and we are looking into some smaller follow up projects we'll hire them for in the future."

Insulation questions, answered by experts

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. 

The lifespan of insulation depends on the material type. Fiberglass can last between 80 and 100 years, but it is important to start checking it around the 15-year mark. Spray foam has a lifespan of up to 100 years, and mineral wool can last up to 100 years. Cellulose, an eco-friendly option, has a lifespan of 20 to 30 years.

Insulation provides additional protection for your tankless water heater. Even if the unit is installed inside the house, it’s still a good idea to wrap the unit up with insulation batts, especially if you live in cold climates. For outdoor units, you can build an insulated box around the tankless water heater for freeze protection.

Yes, doggie doors, like all entrances, can let both hot and cold air into your home. However, as with any door in your house, you can take steps to weather-strip your pet's entrance to prevent air leaks.

We do not recommend fiberglass insulation for soundproofing purposes, especially if you are working on a room that’s part of your living space. Fiberglass insulation is dangerous, and the installation process is hazardous. It is also harmful to the environment. When there are so many newer, healthier non-fiberglass alternatives in the market, the lower cost of fiberglass insulation simply doesn’t justify the harm and danger it poses.
