Frequently Asked Questions and the Answers

Top 5 Questions we hear regularly:

How much do you charge?

There is no one single answer to this question. Each job is priced by the level of service required, magnitude of the work, the complexity of the work, the materials required, and the amount of time required for completion. Our estimators are very skilled at coming to these answers efficiently and accurately.

Can I book an estimate?

Absolutley! Please understand that we are a company who's quality and reputation create large demand for our services. It is not feasible to come to you immediately, however, we strive to maximize our days and to offer each potential client expedient service appointments.

Can you come this week?

No, it is very unlikely. We book as few as two weeks in advance and in peak periods, several weeks ahead. That said, we do have cancellations and adjustments in our schedules daily and we will often contact clients to see if they are able to accept us early.

Do you work weekends?

No. Like yourselves, our crew work very hard all week, often into the evenings, and we respect their need for rest and personal time.

What products do you use?

Each project is specific and unique, we need to know more about your needs before we can answer that efficiently. Our estimators will discuss all options available to you upon site inspection.

Do you work in Quebec?

Yes, O'Reilly Brothers Limited and their employees are licensed to work in the province of Quebec.

What is R-Value?

R-value is a unit of measurement that inidcates the ability to resist the flow of heat through an object or material. A higher number indicates that the object or material has a higher insulating capability via a strong resistance to heat loss. The R-value is a very useful measurement, however, it only measures conduction: where heat escapes through solid objects, which accounts for only 20% of a building’s heat loss. The balance of heat escapes via air moving from one place to another, known as convection.

How much insulation should my home have?

Generally R-40 is recommend for most attics. This translates into approximately 11" of blown cellulose, 15" of blown fibreglass, or 6.5" of sprayed foam insulation.

How do you install insulation in my attic?

Cellulose Installation: Insulation is pneumatically placed using a truck mounted insulation machine. The material is pumped from the machine up to the attic through a three inch hose where the installer carefully applies the required thickness.
Spray Foam Installation: The product is sprayed directly into place onto the work surface (many substrates will accept foam). It is applied as a liquid, using a hose and spray gun set up. It is a combination of two substances that blend together on contact and immediately transform into a thick foam, permanently in place, creating an air-tight seal with any surface to which it is applied. The curing process happens within seconds.

Why would I remove my insulation?

Insulation is often removed when it is damaged by smoke, water, mould or animal infestation. It can also be removed if the homeowner wishes to switch insulating materials i.e. from fibreglass to blown cellulose insulation.

Can we be in our home while insulation is being installed?

Yes. Off-gassing is minmial from all of our products, as per government enforced policies. However, you may wish to avoid the noise and equipment. The choice is yours. Homeowners must be off-site for abatement of asbestos or vermiculite.
