What is the Difference Between Crawlspace Insulation and Encapsulation?

Crawlspace Insulation vs Encapsulation

Crawlspace encapsulation and crawlspace insulation are two distinct approaches to addressing issues in the crawlspace area of a building. Both services are often performed together. Despite this, these tasks serve different purposes. 

  • Crawlspace Insulation - specifically focuses on providing thermal insulation within the crawlspace to improve energy efficiency and temperature control.

  • Crawlspace Encapsulation - crawlspace encapsulation involves sealing off the entire crawlspace area from the surrounding environment. It aims to create a conditioned space by providing a barrier against moisture, air infiltration, and pests.


Why Insulate the Crawlspace?

Benefits of Crawlspace Insulation Toronto?

Specific crawlspace insulation benefits will vary depending on the details of your property and project. Here is a couple of benefits that you may be getting from the crawlspace insulation project.


  • Energy savings - crawlspace insulation helps to prevent heat loss during the winter and heat gain during the summer. By creating a thermal barrier, insulation reduces the transfer of heat between the crawlspace and the living space above. This results in reduced energy usage for heating and cooling, leading to lower utility bills.

  • Increased comfort - insulating the crawlspace helps to maintain more consistent temperatures throughout your home. By reducing heat transfer from the crawlspace, insulation prevents cold floors in winter and minimizes heat infiltration in summer. This can result in improved comfort and a more pleasant living environment.

  • Moisture control - high humidity levels can lead to moisture-related issues in the crawlspace – mold rotting, saggy floors and more. Insulation can act as a moisture barrier, reducing the potential for condensation and dampness. It helps to prevent moisture buildup, mold growth, and damage to the structural components of your home.

  • Improved indoor air quality - crawlspace insulation helps to create a sealed and conditioned environment, minimizing the entry of outdoor pollutants and allergens into your home. It reduces the infiltration of dust, pollen, and other airborne contaminants, leading to improved indoor air quality. This can be particularly beneficial for individuals with allergies or respiratory conditions.

  • Pest control - Insulating the crawlspace can act as a deterrent to pests such as rodents, insects, and termites. It helps to seal off entry points and creates a less appealing environment for pests, reducing the risk of infestations and damage to your property.

  • Increased property value - insulating your crawlspace can be an investment that adds value to your property. Energy-efficient homes with proper insulation are desirable to potential buyers and can command a higher resale value.

It depends. When it comes to crawlspace insulation, there is no one-fits-all approach. During the initial inspection, our team will assess your crawlspace and the issues it’s facing. We will then recommend a specific approach and provide a quote.


Here is an example of what crawlspace insulation project may look like:


  • Assessment & planning - the first step is to assess the current condition of the crawlspace and determine the insulation needs. A professional insulation contractor will inspect the area, measure dimensions, evaluate existing insulation (if any), identify air leaks, and assess moisture levels. Based on the assessment, they will develop a plan for insulation installation.

  • Air sealing - before installing insulation, it is important to seal any air leaks, cracks and other foundation damage in the crawlspace. This may involve identifying and sealing gaps, cracks, and openings in the crawlspace walls, floors, rim joists, and any other penetrations. Air sealing helps to prevent the loss of conditioned air and the entry of outdoor air, improving energy efficiency.

  • Moisture control - if moisture is a concern in the crawlspace, moisture control measures may be implemented. This can include addressing drainage issues, installing a vapor barrier or moisture barrier on the floor or walls, and ensuring proper ventilation or dehumidification or even sump pump installation.

  • Insulation installation - once the crawlspace is properly prepared, the insulation material is installed. The choice of insulation material depends on factors such as climate, budget, and specific requirements. The insulation is placed on the walls, between floor joists, or on the ceiling, depending on the design and construction of the crawlspace.

  • Rim joist insulation - the rim joists, which are the perimeter areas where the floor framing meets the foundation, are often a significant source of energy loss. Insulating the rim joists is an essential part of crawlspace insulation projects. It typically involves installing insulation material, air sealing, and sometimes adding a thermal barrier to improve energy efficiency.

  • Ventilation & airflow management - proper ventilation is crucial in a crawlspace to prevent moisture buildup and maintain healthy air quality. The insulation project may involve evaluating and improving the ventilation system, ensuring adequate airflow, and installing or repairing vents or fans as needed.

  • Quality checks & clean-up - once the insulation installation is complete, our team will conduct quality checks to ensure everything is properly installed and meets the required standards. Any debris or waste from the insulation process will be removed, leaving the crawlspace clean and tidy.


It's important to note that specific steps and materials may vary depending on the unique characteristics of your crawlspace and the insulation requirements.

What Our Clients Say?


Stephanie G.

Residential Client

I used Aquamaster for two separate home waterproofing projects and I was extremely satasified with their work and price. Their team are highly skilled, thorough and were able to complete the 10.5 hour job in one day. They were even kind enough to seal my window frame after I noticed a minor leak. I would highly recommend Aquamaster for all your waterproofing and plumbing needs.

The Aquamaster team is absolutely fantastic! They went above and beyond to diagnose and correct the problem that I had with my basement plumbing caused by old pipes and persistent tree roots. I used them once in 2012 and in 2020. I cannot say enough good things about this team - Highly recommend.
