DM Dependable Maintenance... protecting what's inside - by taking care of what's outside.


Why do I need a building envelope maintenance program?
Regular inspection and maintenance will ensure that any leaks and resulting water damage are discovered and addressed in a timely manner to prevent further damage and expensive repair bills.

How often are inspections and routine maintenance required?
Every building is different. We will customize a maintenance program specific to your building. Please request a free consultation for more information.

Will having a DM Building Maintenance Program guarantee that I will never have a water ingress issue?
No, however breaches in the wall cladding, roof and balcony/deck may occur, but they will be discovered in a timely manner, therefore keeping repair costs to a minimum.

What is water ingress?
Water ingress is a water leak into the exterior of a building. This is caused by rain hitting and running down the outside face of the building, or standing water on roofs and decks. The water enters through a breach in the wall cladding or waterproof roof and deck membranes. You will likely not realize that there is a problem until a significant amount of damage has already occurred. Water ingress creates a perfect environment for mold and/or fungus to grow. This can cause or aggravate serious illness for people living in the home. Our trained technicians will spot these problems before they become big, expensive problems.

What are the benefits of having a DM Building Maintenance Program?
  • Protects your investment
  • Reduces repair costs
  • Establishes a maintenance history which may be required for your warranty, as well as offers peace of mind to prospective purchasers
  • Protects your warranty (if appicable)
How much does the DM Building Maintenance Program cost?
Every building is unique. Our maintenance programs are custom tailored to your building. But, ask yourself this: Would you rather pay a few thousand dollars per year to protect and maintain your building, or pay hundreds of thousands of dollars to repair and restore your building?

British Columbia the Homeowner Protection Act and Insurance Act, Section 14, "Optional Exclusions" states that failure to repair damage or problems, by Stratas being negligent by not doing maintenance at all, or doing maintenance improperly may also void a warranty. DM recommends that owners of Stratas learn about their obligations.

Glossary of Common Terms:

Balcony: A horizontal surface exposed to the outdoors which projects from the wall of a building and is surrounded by a railing, balustrade, or parapet.

Building: A structure with a roof and walls, such as a house, office building, shopping mall, or apartment building.

Building Envelope: The separation between interior and exterior spaces (includes wall cladding, windows & doors, balconies, decks, roof, and foundation). The building envelope also affects ventilation and energy use within the building.

Cladding: The covering of one weather exposed material of the exterior wall assembly with another. The most common materials used are stucco, wood siding, vinyl siding, masonry brick and metal cladding. This provides another layer of insulation and protection where it is needed.

Deck: Horizontal surface exposed to the outdoors, frequently over living space.

Isolated Repair: Repair to the building envelope limited to a specific area of the building.

rainscreen-layers.jpgRainscreen: A moisture-management drainage cavity constructed behind the cladding which provides a vertical drainage path for water ingress to flow down and out, away from the building. Rainscreens reduce the forces attempting to drive moisture into the wall.

FACT: Did you know that Europeans were the first to introduce the concept of rainscreens?

Roof: The structure forming the exterior surface and its supporting structures on the top of a building.

Water Ingress: The penetration of damp from the outside into the structure and interior of a building.
