"The process went very smoothly.  There were several teams that worked on my project.  The initial workers removed all of the old insulation and trash left under the house during construction, and cleaned the joists.  Later a perimeter drain system was installed, and the final job was to insulate the foundation perimeter and install the vapor barrier.  

All the work was done in a professional manner and the workers were all very courteous.  They were on time and on budget."
Unsealed porous foundation walls. Efflorescence has grown along the outside walls.
Plastic is laid out to protect the freshly pained walls and floor.
Open vents in the foundation walls allow outside air and moisture to infiltrate the crawl space, increasing the relative humidity and allowing mold spores to thrive inside.
Spray foam application in progress on warehouse walls.
The dirt floor is exposed, which will allow the moisture from the earth to rise uncontested into the crawl space, adding to the increase in relative humidity.

"I called Evergreen Electric and setup an appointment for the next day to perform what I figured would be a couple small jobs and to receive an estimate to run cable into new rooms. The original appointment was delayed because of a power outage on another job, but speaking to Josh on the phone, he was willing to come by as soon as he was finished even though it would have been well into the evening. I told him the following day would work fine and we rescheduled the appointment.
Josh arrived the next day and examined our situation. Our house is nearly 40 years old and it turns out the problems were much deeper than I thought. Josh crawled into the attic and rewired the junction boxes that were not just loose but had previously been wired incorrectly. He also spent well over an hour attempting to diagnose why our breaker was tripping without much of a load on it. He was very thorough in his troubleshooting. He replaced the breaker with a higher amp version and the problem is fixed, but he also indicated there is likely more faulty wiring running through the attic buried under the insulation and someone should come back to assess the entire electrical system.
Josh was very courteous and professional and answered all of my questions. After spending about 2.5 hours with us, I was expecting a large bill. I was very pleased when he told me he would only be billing me for one hour.
About 30 minutes after he left, we noticed that a light in the hallway would not turn off. I called to report it and Evergreen responded immediately. Josh came back right away and fixed the problem. He even replaced the light switch free of charge. It is nice to see a company that stands by its work and acts so quickly when something is wrong.
I would highly recommend Evergreen Electric. They are prompt, thorough, and stand by their work.

"Just before the heat of the summer began, my air conditioning went out. ARS had maintained my furnace/AC for the previous owner of my home and had done some regular maintenance for me.They showed up the same day that I called, but unfortunately told me that my entire system needed to be replaced.

After doing some research, I decided to buy a new furnace/AC from them. They scheduled an appointment a few days later (they had faster dates, but I was not available), and showed up on time. They did great work and were done in one day.

In point of fact, the furnace that they sold me could not be made to work in the space available, so they gave me an upgrade to a better unit at no additional cost!

While I'm not happy that the old unit died, that's certainly not their fault. They were prompt and professional, and I would happily use them again."

"Expect for them to be on time, that they will cover the floors, that a window may be opened for an extended period if adding
insulation.  There will be loud noise if adding insulation so be prepared.  Find a comfortable place to be while the
work is being performed if you are waiting at the house.

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

"Barry and his assistant showed up and started working on the otuside inspection while we were waiting for the realtor to arrive. They did a thourough visual inspection of the house and made sure that outlets, plumbing, gas and light fixtures were working properly and had the necessary covers on them. After the visual inspection with photos being taken they performed a thermal scan of the walls in the house to look for moisture and possible infestations.

Insulation questions, answered by experts

When installing metal siding, a high-quality house wrap is considered the best protection against condensation and moisture infiltration. House wraps can increase a home's efficiency significantly. However, a house wrap is not a replacement for a vapor barrier because it can be permeable when moist air passes through siding. This is why it's essential to follow manufacturer instructions for insulating siding when installing new siding.

Ideally, you can add new insulation to your existing insulation. However, some circumstances require you to remove old insulation before adding any new insulation: 

  • If the insulation is over 15 years old

  • If the insulation is wet or moldy

  • If it is vermiculite insulation

  • If you see signs of pest infestation

Removing old insulation is best left to a pro who can safely dispose of potential moldy or asbestos-ridden insulation.

Depending on the size, insulation condition, and removal method, it can take anywhere from four hours up to twenty hours. Therefore, be prepared to split the projects into phases, or leave it to a professional. Insulation is an intermediate project with various risk factors and can be challenging to someone unfamiliar with the process.

The cost of installing spray foam insulation is $2,760 on average, but this cost can be as low as $650 or as high as $7,700. The main cost factor is the size of the insulated area and the type of spray foam insulation. 

Polyurethane spray foam costs between $0.44 and $1.50 per board foot, where a board foot is equal to the volume of a one-foot length of a board. More expensive options, like soybean or vegetable oil spray foam, range from $1.50 to $3.00 per board foot.

Three signs that you need crawl space insulation are drafts, high energy bills, and mold. Drafts can start in crawl spaces and cause hot or cold air to spread to the rest of your home through holes in the floors and walls. And even if your entire home is well-insulated, you can still feel an unchecked draft from your crawl space and in your utility bill. Uninsulated crawl spaces can let in air and moisture, and because they’re built directly on the ground and difficult to dry out, they are hotspots for mold and mildew.
