Many hands are involved in the construction of a home. The trades and technicians take pride in their work and will complete repairs to anything that has gone wrong during specified warranty periods. The warranties provided are in effect as long as the installation is not altered.

Here are some common causes for cancellation of warranty.

Basement Developments

During basement development, ductwork is altered, electrical systems are added or moved, plumbing lines are moved, insulation is added or removed.Furnace and hot water tanks are altered or moved. Development of a basement typically involves a lot of changes to major components and delivery systems. Once these components are altered, the original warranty will be voided.

Air Conditioners

It is best to purchase and install an air conditioning unit from the heating company that installed the furnace in your home. A/C installation will affect the electrical and heating elements of your home. If the unit is not sized properly for the home, it can affect furnace performance. Improper installation methods can also cause furnace breakdowns which would not be covered under warranty.

Garage Door Openers

Installing your own garage door opener can void some of the warranty on your garage overhead door. If you are adding or replacing an opener, wait until the current warranty has expired or install an opener from the company that provided the garage overhead door.

Common additions such as hand held shower wands, soap dispensers, bidets, etc. can void the warranty on the plumbing fixtures to which they are attached.

Window Warranty

Installing black out blinds or after market frosting/tinting products can void the warranty on the entire window unit. These products have the potential to superheat the window unit and can cause warping of the frame or fracturing of the glass.


The most common cause of a warranty cancellation is salt damage.  Most homeowners are aware that they should not salt their concrete.  What is not so widely known is that tires carry road salt onto driveways. Proper maintenance of concrete is essential. Apply a sealant annually – this will not prevent salt damage, but it can help slow down the effects of weather in our Alberta winters. Concrete de-icers that say “safe for driveways” should still be checked to ensure the list of ingredients does not contain any sodium chloride (rock salt) or other corrosive substances. Any de-icer, no matter how safe for concrete, should be shovelled away as soon as the bond between ice and concrete is broken.

If you are making changes in your new home while under warranty, remember to check if permits are required. If you are not certain of the ramifications of the proposed changes, contact the Warranty department or contact the original installer directly to find out how your plans will affect your warranty coverage.
