"We re-sided our 1929 house recently, and during the tear-off phase it was the perfect time to have blown-in insulation performed to insulate our exterior walls. Ryan and his crew worked quickly and we are so much more comfortable with our walls finally insulated. We had a minor repair needed as a result of the drilling, and the company worked quickly to resolve it to our satisfaction. I will happily recommend them to others, and feel like this project pays for itself quickly in terms of energy efficiency and comfort."

"I had an extensive rat issue in the insulation under my house. The Crawlspace Crew came over the same day to give me a quote and inspect my crawlspace. They organized the entire job, including removing the insulation, setting up a new barrier, spray underneath my house with an antimicrobial chemical and reinstalling new insulation. They also orchestrated with a pest control company to come and set traps, and close up any holes that were ports of entry for the rats. They were extremely efficient at communicating back with me and Two to the timeline. Overall, I was very impressed with the Crawlspace Crew."

"I got a rebate from the state for having this service done. Their were two men that came out and they were able to get it done within two days. They put insulation in under our home and in the attic. I did notice a difference in our home after this. They were very professional and you could not even tell they were there."

"I bought the $99 furnace service in October for a furnace that was going in and out and also needed cleaned, as well as to see if there were any parts that would help it work better. The igniter was replaced, although I thought the price a little high at $275, not including the servicing purchase. The furnace worked fine until January when it quit completely (as we had kind of anticipated although the furnace was not ancient, it was 12 or so, and no fault of Sun Glow, a different part froze up). I got an estimate from a couple of companies and ended up picking another for the new furnace, primarily due the the other installer measuring the rooms in the house and checking the insulation properties of the windows rather than basing it on a square footage estimate alone. From what I have read, our old furnace was too big for the house and that may have contributed to it's earlier than expected demise. The new one is much lower in BTUs, and both companies provided estimates with a smaller furnace than we had previously, but Sun Glow picked a larger one that than was eventually installed. Pricing appeared similar, but hard to tell with different brands and sizes of furnaces, filters, etc. in the estimates. The estimater was professional, prompt, and came at very short notice. So although, I didn't chose this company, I had no problems with their service work and would call them again for another estimate.

Insulation FAQs, answered by experts

Installing new insulation in a home is worthwhile if your existing insulation is old and has lost some of its insulative capability or if you don’t have insulation installed already. Installing new insulation will boost your home’s energy efficiency, which can reduce your heating and cooling bills and save money on HVAC repair and maintenance in the long run. New insulation also keeps your living space more comfortable, so you and your family will benefit from the work as well. Finally, installing new insulation boosts your home value, making it especially worthwhile if you plan to sell.

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. 

Yes, there are government incentives available in some regions for insulating air ducts as part of energy-efficient upgrades. These incentives aim to encourage homeowners and businesses to improve energy efficiency and reduce their carbon footprint. To determine whether you qualify for such incentives, check with your local utility company or government agencies. They often offer rebates, tax credits, or other financial incentives that can help offset the cost of duct insulation projects.

Whether you should remove old insulation before blowing in new insulation depends on your particular situation. Fiberglass insulation attracts insects and mold over time, so if it has been decades since your last insulation upgrade, consider removing the old materials before placing the new ones. However, most types resist mold, insects, and mildew, so once you get the go-ahead from your contractor that your space is free from all three, feel free to install the new insulation directly on top of the pre-existing materials.

Yes, exposure to fiberglass insulation can cause harm to your skin and eyes. However, this typically refers to the fiberglass insulation that is mostly used in walls and attics. Fiberglass doors don’t pose risks for fiberglass exposure because they're fully encased in polymer cladding.
