"George came out promptly and did a thorough inspection of the crawlspace and provided options on what can be done. The insulation work was performed by Jesus who also found and fixed two foundation cracks. Encapsulation was done by Juan's team and they all did a great job. They were able to perform all the work with a very narrow opening into the crawlspace and were also able to fit in the dehumidifier. After installation there was a minor issue with the dehumidifier and Craig came right away to fix it. Great experience and I'd definitely use their services in the future if need be."

"Fast work. Great communication up until trying to communicate with project manager. Was told everything would be completed within two days. The roof was done in one which was awesome, but I am still waiting on gutters a week later and won't be given a day/time for them. Just keep being told "early next week" or "tomorrow". Sales portion and inspection went great. Fantastic everything up until the install."

Insulation questions, answered by experts

The best time to insulate a garage ceiling is when the weather is mild and dry. That means it shouldn’t be stormy, snowy, or raining, and the temperatures should be comfortable. Ideally, you’ll insulate your garage ceiling in the fall, before winter hits. Not only will you be the most comfortable, but you’ll also likely see the greatest energy savings heading into the colder weather with a newly insulated garage.

In some areas, insulation companies require a special license, while some states only require them to hold general contractor licenses. Some municipalities may not mandate any license, although you should always ensure a contractor is fully insured. You can use Angi’s license lookup tool to confirm whether or not an insulation contractor you’re considering holds the necessary license for your area. You can also contact the company for information regarding licenses, certifications, and insurance.

Yes, PEX pipes should be insulated in certain situations. While insulation is not always necessary for pipes running through insulated interior or external walls, it is recommended for any pipes located in uninsulated rooms, unheated areas, or outside, especially in regions with cold winters. The primary reason is to prevent freezing. Although PEX is more resistant to cracking from freezing than other materials, repeated freezing and thawing can weaken the pipes over time, increasing the risk of a burst.

You don’t need to staple insulation, as your drywall and studs will hold it into place. But if you already have a staple gun and staples lying around, it can help keep the product in place and avoid any shifting. But, most experts agree it’s an unnecessary step.

If you’re adding a vapor barrier, you will need to staple that in place.

The most affordable way to insulate behind unfinished walls is to install fiberglass batts or rolls. These total around $0.75 per linear foot, with the width matching the gaps between standard studs perfectly. However, it’s important to consider the R-value of your insulation and the climate in your area, as fiberglass insulation isn’t the best in terms of preventing heat transfer. Plus, the most affordable option may cost more on electricity bills over time. The most affordable way to insulate behind finished walls is to leave them up and use blown-in insulation to avoid drywall replacement.
