How do I choose an Insulation Contractor?

There are many considerations that go into choosing the right contractor for your insulation installation or removal project. Below are the most important items to consider:

  • Credentials. The right contractor should be licensed, insured and certified for the work to be performed.
  • Experience. The contractor you select should have many years in the insulation business and have expertise working with the many different types of insulation. With this experience, you can be sure that they will be able to install the insulation type best suited for your situation.
  • Trucks & Equipment. Especially with spray foam insulation, you will want a contractor that has a multi-truck fleet at their disposal so that they can quickly replace a truck that breaks down.
  • Reputation. Check the references of the contractor or research online for testimonials for the contractors you are considering. Knowing the track record of the contractor will give you a good indication if they are the right contractor for you.

What is minimum building code for attic insulation?

Minimum building code for an attic is R-50, but it is minimum for a reason, it is the absolute minimum a builder is required to install in a new home. If you are paying for the heating and air conditioning more is better in this case, to protect your heating and cooling dollars.

What is the best type of insulation to use in a basement?

We recommend spray foam, as it adheres to almost any clean, dry, surface it is sprayed to. Spray foam is recognized as an air and vapour barrier after 2-inches thick (50mm). If your studs are off the foundation wall the spray foam will expand in behind the studs making this application virtually seamless, making heating and cooling this area much more efficient.

What is the best insulation for flat attics?

Our answer is always spray foam, but blown insulation in very cost effective for flat attic areas as well and is the most common product used.

How do I fix a cold room over a garage?

We usually find that the builder has used fibreglass batting and the only way to fix this correctly, is to remove the drywall and existing insulation and spray foam these areas. This will stop the cold air from penetrating this area making the rooms above much warmer. Also the duct work for heating these areas often runs through the floor joists and in the garage walls, by improving the seals around the duct work will ensure that the heat intended to get to these rooms is actually still warm when it gets there.

Can I insulate existing walls in my older home?
Depending on the wall make up, we have 2 different applications we can do to improve the insulation in the exterior walls. Every situation is unique as far as wall make up, what is in the wall, how deep is the cavity etc. We always come out and provide a free onsite estimate for this type of work.

My floors are cold on the main level, is there anything I can do?
There are a couple of reasons or situations that may cause cold floors. If there is a crawlspace or basement under this area that is lacking in insulation this may be the problem. There may be lack of insulation in the ring joist or the main floor walls as well.

I live in a 2 storey home and the upstairs is hot in the summer and cold in the winter?
This is usually due to lack of insulation in the attic or poor airflow in the attic or a combination of both.

I live in a 1.5 storey and the upstairs is hot in the summer and cold in the winter?
These homes are very unique and take very careful decision making on how the space is used. There is usually a combination of 3 areas to be addressed, a small upper attic and knee walls on either side of the house or all the way around the house. It is imperative to insulate all 3 properly, otherwise the areas not insulated properly become the weak point of the attic/insulation system.

How do I properly insulate my crawlspace?
There are 2 ways to properly insulate a crawlspace. 

  1. If you have a heat source in the crawlspace we would put a 6-mil vapour barrier on the dirt or gravel floor and spray foam from the floor above, down all outside walls, sealing to the 6-mil vapour barrier. 
  2. If there is no heat source in the crawlspace and one cannot be added cost effectively, then spraying 5-inches or more of spray foam on the underside of the floor would be the alternative.
