Stucco Home Insurance: How Does EIFS Affect Insurance

Stucco (or more accurately, EIFS) is enormously popular on homes in and around the Greater Toronto area due in large part to it’s great aesthetic appeal and it’s ability to insulate, thereby reducing heating and cooling bills. It’s become a “hot topic” (pun intended) for insurance companies – moreso in the U.S. than Canada – over the past few decades because of problems if improperly installed. Problems which range from moisture intrusion and entrapment to the combustibility of it’s components and decorative accents.

Before starting any home improvement project, it’s a good idea to call your insurance provider to check whether or not it will affect your home insurance policy. Failure to contact them and update your policy when changing something as drastic as the exterior walls on your home could actually void your home insurance warranty.

Think about it… let’s say you retrofitted your home with stucco in July of 2012 at a cost of $12,000 and were happy with the contractor – he was polite, on time, did everything according to the contract and finished on a good note. 3 years down the road (it’s 2015 now) you have a building inspection completed for termites because it’s been an issue in your neighbourhood. During the inspection, the home inspector doesn’t find any termites, but notes that you have moisture trapped in your walls – around the windows, wherever. Remembering that mould is somewhere in your insurance policy, you contact your insurance provider who sends someone out to investigate and they’re shocked that your home doesn’t match what’s on the paperwork. Your insurance company won’t cover the damage any more, because what you’ve been paying for does not have EIFS-related coverage. Let’s take a look at some of the damages you’ve incurred:
- Insurance: 36 months x $200/month = $7200
- Removal of EIFS: $4,000
- Removal and repair of mould/moisture damaged wall section: $7,000
- Reinstallation of EIFS, done properly: $13,000
Total: $31,200

That’s $31,200 out-of-pocket expense that is related to your one forgotten phone call to your insurance company. Note that properly installed EIFS usually is slightly (give or take 10%) more expensive than the shmuck who cut his costs by cutting required material out of your home. Good luck finding him too – the average “stucco contractor” is in business roughly 2 years before closing it down and opening another or going to work with a friend.

If properly installed, and done in accordance to local building codes (following fire code where necessary), EIFS is a worry-free system that will last decades and save you thousands of dollars in heating and cooling bills. The trick then, is to find the right contractor – one that has a proven track record and can be vouched by manufacturers and previous clients. Services like Stucco Toronto can put you in touch with multiple contractors, are provide a neutral – 3rd party approach to your project.

The takeaway from this article is this:
1. Make sure you contact your home insurance provider to include coverage of EIFS, which may or may not affect your policy.
2. Compare quotes and get recommendations from suppliers/previous-customers, but don’t try to force a contractor to lower their prices to the point where they are going to cut corners – you’re the only one that will suffer in the end.

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.

Mouldy Hardie Board Removed
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.

EIFS With Horizontal Adhesive Channels and No Moisture Barrier

EIFS With Horizontal Adhesive Channels and No Moisture Barrier

This is the epitome of poor EIFS construction and I hope that both the applicator and builder were sued into oblivion. For starters, yes that black mass is mold, and black mold may or may not be toxic. As you can see, the mold originates where moisture is commonly a problem — around the window. What the common home owner will not notice about the EIFS installation is this:

  1. There is no moisture barrier to keep the water off the substrate, which is there the mold would grow. Any water that gets behind the EIFS barrier is going to create the perfect environment for mold growth
  2. The substrate is plywood, which is currently not recommended by EIFS manufacturers
  3. Those white stripes are channels of adhesive, using a 3/8″ notched trowel. The channels were actually installed in a HORIZONTAL pattern, trapping any water that tried to run down the substrate (where it shouldn’t be anyways). This installation is beyond stupid and makes me feel like Gordon Ramsey.

Just to clarify however, modern EIFS (when correctly installed) would not use wood as a substrate, would have a moisture/weather barrier over the substrate, and is installed with VERTICAL channels of adhesive, allowing water to run down the wall and not become trapped. These problems are by no means on every EIFS application, modern exterior insulation finish systems have corrected these problems, but is not uncommon in older installations with poor applicator training.
