Seattle Crawlspace Insulation Specialist

If you want to reduce your heating and cooling costs, make sure that your crawlspace and floors are properly insulated. Not only will this make your HVAC system more efficient, but you will also increase the value of your home at the same time!

Reasons for Insulating My Crawlspace

Too many homeowners neglect to properly insulate their crawlspace. This means that the home’s energy efficiency suffers, and can lead to problems down the road. Contact Guardian and have one our knowledgeable technicians check your crawlspace for these signs of trouble.

  • Missing insulation between floor joists
  • Water pipes without insulation
  • Insulation that is falling or loose
  • Water in your crawlspace
  • Gaps between your insulation and your subfloor
  • Properly set vapor barriers of black plastic

With any one of these symptoms, your crawlspace needs an upgrade to its insulation. At Guardian, we can make sure to get the job done right on our first visit and make your home as energy-efficient as possible. 

The rules regarding crawlspace insulation are fairly recent. It wasn’t required in newly built homes until 1992. Without insulation, a home can lose approximately 25% of its heating and cooling through the crawlspace. If your crawlspace is full of cool air, then it will draw energy to try and heat it up. According to the Department of Energy, a minimum of r-25 insulation should be installed in homes to keep them as efficient as possible. 

Vapor Barrier Services in the Seattle/Tacoma Area

A vapor barrier works by protecting your crawlspace insulation. It is made of plastic and prevents moisture from getting into the insulation and weakening it. This also protects the rest of your home by keeping that moisture at bay. 

Weatherization Options for the Seattle/Tacoma Climate

At Guardian, we offer a wide range of weatherization options for your crawlspace and floor insulation. 

Vapor barrier and ground cover will make sure that moisture can’t penetrate your insulation and your home. It will keep mold and mildew from forming, and deter bugs and pests from infiltrating your crawlspace. These are valuable ways to protect the investment you’ve made in your insulation, and in turn your home. 

The pipes for your plumbing also require a thermal barrier that will keep them from freezing and save you energy by keeping your hot water from cooling down. This barrier will prevent a loss of energy and save you money on your utility bills. 

Floor air sealing is the process of sealing up any gaps or spots where air can leak through. This will help your HVAC system work more efficiently, and those gaps can also be an entry point for critters and insects. 

Crawlspace Insulation Frequently Asked Questions


What Happens to a Crawlspace?

It is not uncommon for homes in the Seattle/Tacoma area to have crawlspaces. They tend to be underneath all or part of a home, and are just open space. Some can be used for storage as well. They tend to be more prevalent in areas with soil that’s high in moisture. The insulation placed into the crawlspace keeps that moisture from the soil from getting into the home. 


How is a Crawlspace Properly Insulated?

The best option to properly install insulation is a trained professional from Guardian. They will assess your crawlspace and determine what kind of space it is, what insulation type would be most appropriate, and how much is needed for the job. 


Is Insulating a Crawlspace Really That Important?

Yes. An improperly insulated crawlspace, or one that isn’t insulated at all, can cause many possible issues for your home. For example, any water pipes that might run through the crawlspace could freeze. You may also have HVAC ducts that can get damaged as well. Bugs and pests may also find it easier to sneak in without proper insulation. Lastly, a well-insulated crawlspace will keep a home more comfortable, and allow the HVAC system to run more efficiently.
