Toronto Sun Article: Toronto Housing Stock

Article on Toronto's Housing Stock from the Toronto Sun

I was wondering where I could find this sort of information the other day.

Excuse the bad picture. Transcript below.

Homes in Toronto are aging. That typically means they need repairs or full retrofits depending on the original quality of the construction. Even homes with ultra-durable brick cladding are beginning to see the wear-and-tear of the fluctuating Toronto weather that ranges from -40 to (especially recently) +40. Our winters are colder and our summers are hotter than most other places across Canada (and the states), meaning our buildings are subject to a range of different forces and building to deal with them all is at times, difficult.

The typical lifespan of brick from the 80s and earlier is roughly 50-80 years depending on how well it was maintained. This could be shorter due to the builder using cheap bricks that aren’t as dense or well manufactured. What’s important to realize is that upwards of 50% of Toronto’s brick homes (the period before 1980) do or will soon need some sort of maintenance.

Home owners that have brick that is decaying have a few options. The first is tuckpointing, which will fill in places that the mortar has begun failing early. This helps in situations where the damage is isolated, and is typically exasperated by running or dripping water. Tuckpointing is like applying a band-aid to a staph infection, it temporarily covers the problem but it’s only going to spread and get worse with time.

The second option is to replace the brick in sections where it’s really beginning to become a problem. Slightly better than tuckpointing because the brick is being replaced as well, but still costly when considering the quantity of work that is being done. Not only is it costly, it only addresses the portion that needs work NOW – the rest of the walls will be due in another 10 years anyways. Replacing sections of brick on your home is akin to putting a new door on your ’95 Corola when the rest of the body is about to fall apart.

The final option is to re-clad your home. This can be done by tearing down the existing brick (time consuming and costly) and putting something new up, or by going directly over the existing brick with a new cladding. New brick can be put back in place of the old brick if required. The advantage to going about re-cladding the brick before it’s in such bad condition that you can’t use it as a substrate, is that you can avoid the expense of tearing it down and disposing of it. Re-cladding the brick is also a more environmentally-friendly alternative because the waste doesn’t end up in landfills, nor is fuel used getting it there.

There are dozens of recladding siding options – vinyl siding, aluminum siding, cedar siding, hardie board, EIFS (“stucco”). The only ones that are designed to incorporate insulation boards to help reduce heating and cooling bills are vinyl siding and EIFS. Of those two options, EIFS is the only one that uses trowel-applied cement that can seal in and protect the brick from further decaying.

EIFS (Exterior Insulation Finish Systems – what is commonly called “stucco” in Toronto) incorporates a monolithic styrofoam layer that helps reduce heat lost or gained through the walls of a home. This can have an effect of reducing heating and cooling bills by upwards of 30% depending on the original state of insulation within the walls. In addition to protecting and therefore preserving the existing brick so that it does not need to end up in a landfill, EIFS represents an environmentally responsible option for re-cladding.

The outer layers of EIFS include a cement coating embeded with a fibreglass mesh to prevent cracking, and a beautiful finish coat available in any colour. A manufacturer’s colour chart can be supplied by the stucco contractor, or if the home owner already has a colour selected from a paint sample, EIFS manufacturers are capable of doing an exact match.

 Housing stock and energy efficiency
High energy costs, notably for gasoline and ome heating, are damaging consumer confidence, purchasing power and spending. Rising prices add urgency to the need to reduce household energy consumption, Adrienne Warren of Bank of Nova Scotia writes in a special report.
“From the perspective of households, reducing energy consumption, or at least slower it’s rise, could generate significant long-term cost savings.
But new construction – which can integrate major energy-saving measures – takes a long time to have an effect on the aggregate housing stock, she points out.
Meanwhile, Canada’s housing stock is aging. Most homes were built before the 1980s and are far less energy-efficient than recent construction, and data suggests that over one-third need repairs.
Energy-efficient renovations and retro-fits have the potential to make a bigger impact in driving improvements in the housing stock, she says.
The looming higher cost of borrowing and more subdued outlook for home sales could put a damper on renovation spending, yet there are affordable cost-saving options, and programs and incentives provided by the different levels of government, she writes.

Caulking Integrity with Stucco

One of the primary reasons that EIFS (Exterior Insulation Finish Systems) has been targeted by insurance companies and cities is because of “failures” it has experienced around window and door openings. The problem lies primarily with improperly installed caulking failing (i.e. the wrong type being used), an integral part of all projects that no one specific sub-trade seems to want to take responsibility for. The result of failed caulking was water intrusion, leading to mould growth – which is harmful to occupant health and can lead to further damage to the building structure. The failures that resulted were not worse than other sidings like hardie board, vinyl, T-111 – but because of the drastic increase in the use of EIFS  in new construction and renovations and lack of proper installation procedures, certain projects have received widespread attention.

What can be done to help prevent this moisture entrapment issue? The best ways to ensure that new construction and renovation projects avoid trapping moisture is to ensure that the modern EIFS installation procedures from the manufacturer are followed – that is; proper drainage using vertically channeled adhesive and grooved insulation boards. On older installations, home owners should be checking their caulking every couple of years to ensure that cracks and delamination is not occurring. By ensuring that the caulking is sealed between two points, you are eliminating any chance of moisture getting in behind the EIFS and causing rot, mold or decaying situations.

Caulking will ideally need to be replaced roughly every 10 years. This seems to be the time period between the new installation of low-modulus sealant (caulking) and when it tends to crack or delaminate to the point where moisture has the opportunity to enter and cause problems. If the caulking reaches the end of it’s life before the 10 year mark, it should be removed and fresh caulking reinstalled in it’s place. While caulking is not specifically the role of the stucco trade, ensuring that it is in good condition will help prolong the life of your stucco cladding.

There aren’t an unlimited number of caulking colours, but you can usually find one to match your stucco wall colour closely. For additional information or help on your new construction or renovation project, contact us.

Hardie Board Removal Reveals Mould and Rot Damage

Hardie Board is a product similar to EIFS that has quickly gained popular in the states and is on is making it’s way into the Canadian market. With great reviews and a high ROI (Remodeling Magazine), Hardie Board seems like a great siding for many who need not worry about insulating value. Unfortunately, it didn’t take the hard-learned lessons of the EIFS industry to heart. With a laxed grip over installation procedures, many projects were installed incorrectly – without underlying weather barriers or methods to allow moisture to escape. The result is what you see here.

Hardie Plank Caused Rot - Removed
Trapped Water Beneath Hard Board

As you can see, the problem area is where most problems occur – around the wall penetrations (windows, doors, fixtures) and the corners. The project featured here even appears to have had the weather barrier installed.

No doubt it has a bright future in coastal areas where hurricanes and tornadoes can cause damage to walls, if it can just get it’s act together, and fast.
