What’s Mold Got To Do With It?

Mold is a problem that most homeowners have to deal with at one time or another. It’s the damaging by-product of water and moisture that can wreak havoc on your home, and more importantly, your health. So with spring on the way, now is a good time to inspect your house for mold and get rid of it before it does any kind of serious damage. But first, it’s a good idea to learn a little more about this pesky organism and why it demands to be treated so seriously.

You might be familiar with mold (otherwise known as mildew) from your shower or bathtub. Since the shower is often wet and the tiles are waterproof, water can sometimes seep into the grout, which, if it’s old and can’t handle its repelling duties properly, can become a breeding ground for mildew. So you’re left with microscopic organisms that feed off the moisture, allowing it to grow until you nail it with some Tilex and wait for the next clean. But what happens when mold starts to grow in the places you can’t reach to scrub – places like your ceiling, inside walls or attic? You’re probably saying, “Not in my house”. Well, guess again.

At least half the homes I visit for improvement and remodeling projects have a major mold problem and the owners don’t even know it. How? Besides that well-known smell at the source, mold generally grows in places that you can’t see – like inside the walls and attic. What most people don’t realize is that mold reproduces, or grows, by releasing spores that you’re breathing in day after day.

How common is this? If you’ve ever had a leak, you’ve most likely had a mold problem. So what can you do about it? You can prevent mold by ensuring your home stays dry. Here are my top tips:

1. Keep your gutters and downspouts clean and clear so water can drain away from your house.
2. Don’t let a leaky roof go unfixed.  Get it patched up immediately and ask your contractor to inspect for any mold growth.
3. Make sure the ground around your house doesn’t slope inward towards the foundation where water can idle.
4. Inside the house, beware of any discoloration in the ceiling.
5. Ensure high moisture areas like bathrooms are well ventilated with good ceiling fans.
6. If a leak has poured into the carpet, don’t just leave it to dry. A damp area can attract mold in less than 48 hours.
7. Ensure large appliances such as refrigerators and washing machines aren’t leaking and have a catchment tray in the event of a malfunction. 
8. If you use a humidifier, make sure it’s cleaned and the water is changed regularly.
9. If you feel that your house or basement has a high level of moisture, consider purchasing a dehumidifier to regulate the humidity and remove any excess moisture from the air.

If you’ve had a mold problem that you’ve tried to control by scraping, cleaning and repainting the area, don’t make the same mistake twice. If the mold keeps coming back, that means the issue runs deeper than the eye can see. It’s time to call in the pros.

Get rid of ice dams once and for all

Last week we talked about ice dams, the pesky water build-ups that freeze in your gutters and leave a massive frozen dam that can wreak havoc on your house. As temperatures below freezing become a more regular occurrence for us Connecticutians, it’s a good idea to understand how you can prevent ice dams, and how to safely remove them as a temporary measure.

Ice dams generally form on the outside of homes that aren’t properly insulated and ventilated. The snow and ice on the roof begins to melt, and it slides down the pitch before refreezing into what eventually becomes a nasty layer of ice build-up. Because the water doesn’t have anywhere else to go, it can start to seep into your walls, causing costly leaks inside the home.

So how do you stop this from happening? Firstly, take advantage of a free insulation inspection offered by a local expert. A remodeler can check your attic to see if you have sufficient insulation and ventilation. Over 75 per cent of homes I visit don’t have proper insulation, which will not only allow ice dams to form, it will also let that brutal winter wind come right into your house. Luckily, insulation is an easy and cost-effective solution, which pays for itself in both energy efficiency and resale value. 

A quicker fix is to use heated cables, which you can buy at your local hardware store. By installing these cables on the base of your roof, you will level out the temperature, allowing the snow to melt and the water to drain off the roof and through your gutters like it’s supposed to. Of course, the cables must be installed before the snow hits, when your roof is dry. A 200-foot cable will run you about $150.

These solutions are both very effective, but what if you have an ice dam now? Firstly, be very careful about hacking at the ice with a shovel or pitchfork, as you’ll very likely damage your roof or gutters, and possibly injure yourself in the process. If you have a leak in your attic, start by using a fan to blow cold air at it, which will equalize the temperature and temporarily stop the water from getting in. Then start to pull any excess snow off the exterior of the roof with a shingle safe roof rake. Once the roof is clear of snow, you can use calcium chlorate ice melter to begin tackling the dam. If you have some old, long socks or a pair of pantyhose, you can fill them with ice melter to keep it in place, rather than allowing it to run off the roof with the melting ice.  Keep an eye out for ice melters that are specific to roofs, so you can be sure the chemicals won’t damage your shingles. Do not use rock salt! 

Remember, this is only a temporary fix and won’t prevent future ice dams from forming.  Also, ice dam removal can be dangerous work, so only attempt it if you are very comfortable working on a ladder. If not, contact a professional for help.

Beware of ice dams this winter

One of the perils of living in New England is the cleanup of the winter weather that so often blows our way. In addition to the ice chipping and the snow shoveling, there is one more serious homeowner hazard that can create a headache both inside and outside, and cause major damage your home. The culprit I am talking about is ice dams.

Let me give you some background. An ice dam forms when heat from inside your home causes snow on your roof to melt and the water to trickle down into the gutters. This sounds like what is supposed to happen, except that when the water slides down, it can often refreeze before it drains because the temperature changes from the top of the roof to the bottom. As the water moves it refreezes, causing a blockage in the gutters and drains. Since the water has nowhere it go, it builds up, and looks for other places to go, such as under your shingles. The snow continues to melt, refreeze and accumulate, growing aggressively until you have what we call an ice dam, or a large mass of frozen water that grows from your gutters and the base of your roof.

So why does the temperature change? Well that’s easy. We all know that heat rises, and when your house isn’t properly insulated or ventilated, the heat from the living areas of your home will rise into the attic, hitting the highest temperatures in the very peak of the roof. So it’s no surprise that snow starts to melt at that very point, where the temperature can easily rise to 32 degrees Fahrenheit, or melting point. As the water makes its way down the roof, the temperature decreases; enabling the water to refreeze by the time it finds its way to your gutters. As that water builds up, it begins to form an ice dam. 

Have you ever looked around the neighborhood and seen a house with big beautiful icicles hanging from the roof? Those icicles aren’t just a pretty bi-product of winter weather; they are a sure fire sign that an ice damn is forming.

Ice dams can be a real problem, especially in older homes that aren’t properly insulated and ventilated. As the water builds up, it can leak into the house and cause damage to the walls, ceilings, insulation and other areas. Additionally, an ice dam that is melting can channel water down into the foundation, which can cause leaks and mold formation in the basement.

Worried about ice dams damaging your house? Next week, we’ll talk about the ways to temporarily fix them, and what you can do to ensure they don’t pop up again next winter.
