Is your home making you sick? It could be. If you’re suffering from constant cold or flu-like symptoms seemingly only at work or at home, you could be at risk of sick building syndrome. Sick building syndrome is when mold, bacteria, or other conditions are making occupants of that building sick with symptoms that only stop when you leave the building. Learn more about the signs of sick building syndrome is and what you can do to prevent it.



What Are the Symptoms of Sick Building Syndrome?

Not to be confused with the common cold, sick building syndrome can create a number of symptoms, including:


  • Runny or stuffy nose
  • Nosebleeds
  • Sore throat
  • Shortness of breath
  • Tightness in chest
  • Sneezing
  • Fever or chills
  • Dry, itchy skin
  • Headaches
  • Dizziness
  • Irritability
  • An inability to focus
  • Nausea


What makes sick building syndrome different from the common cold is that these symptoms keep coming back. If you find these problems disappear when you leave your home for a few days or even hours but come back full force when you return, that’s a sign something in your home is making you sick. Here are six ways you can prevent it and keep you and your family healthy.


1. Keep Dust Away

If your home is prone to dust and clutter, keep it clean! A quick dusting goes a long way in preventing cold symptoms, as dust often leads to mold, which can lead to sick building syndrome. Regularly dusting can also help anyone in your home who suffers from allergies or asthma.

Quick tip: Make sure the vacuum you use has a HEPA filter to help keep allergies at bay.


2. Change Your Air Filter

If you have a filter connected to your furnace, make sure to change the filter every few months to keep your indoor air quality high and keep your furnace working longer. You may need to change this filter more often if you have pets or your house is more prone to dust. If you can’t remember the last time you changed it, it’s probably time! Your lungs will thank you for it.

3. Open Your Window (When Possible)

Opening your window can keep the air moving in your home and push stale air out and let fresh air in. While we don’t recommend opening your window in the middle of winter or the middle of hay fever season, letting in fresh air when possible can help keep the air moving. If you can’t open your windows, invest in some fans to keep fresh air moving in and unwanted microbes out.


4. Look for Mold

Mold is one of the more common causes to sick building syndrome. In fact, when left untreated certain strains of mold can turn into more extreme issues such as legionnaires’ disease. Some of the more common signs of mold are:


  • A musty, earthy smell
  • Discoloration in your walls and ceilings
  • Water stains
  • High humidity in your home


Mold can show up anywhere, not just your kitchen and bathroom. If you suspect you have a mold problem but can’t find where it’s hiding, call a restoration company to provide a professional mold inspection. Not only can they find hidden mold, they can also take the next steps to remove it and make sure it doesn’t come back.

5. Weatherproof Your Property

Minnesota is prone to harsh winters that can create a variety of water damage issues. ¥our pipes can freeze, leading to a burst pipe. Any kind of water damage can create a mold infestation, which in turn leads to sick building syndrome.

Prepare for colder weather before it becomes a problem. A few things you can do are check your doors and window frames for mold, and make sure your chimney is clean.

6. Choose Different Cleaners and Detergents

Cleaners and detergents could actually be the cause of your sick building syndrome. If you’re constantly using harsh chemicals that emit strong fumes, rethink your cleaners. Natural or organic cleaners can be just as effective and sometimes cheaper! Have a clogged sink? Consider these other ways to get your drain flowing again without using chemicals.

Natural disasters are unavoidable and often happen when you least expect them. But what you can control is how you recover from these disasters. Homeowner’s insurance brings peace of mind during these emergencies and can help cover your losses when lightning (or another natural disaster) strikes. To help you prepare for those inevitable storms, it’s important to know just exactly what kind of disasters your insurance covers. Keep reading to learn more! Know Your Insurance Homeowner’s insurance protects you financially against covered damages to your home and personal belongings. There are several policy types offered for home insurance. While no policy covers all natural disasters, some will cover more than others. Depending on where you live, certain disaster coverage may not apply, which is why it’s important to find the right policy for your home. Common policies range from HO-1 to HO-8, with HO-1 being the most basic. Do your research, then make the best decision for you! What’s Covered? Before you assume your home is covered, double check your insurance policy or consult your insurance agent to make sure. While every policy has its own add-ons or exclusions, here are some natural disasters many insurance policies cover. Tornadoes & Hurricanes Tornadoes are fairly common in Minnesota and can be extremely destructive. If your home is involved in a tornado, it will likely cause damage to your personal property due to the strong winds, hail, and strong chance of fallen debris. Most homeowner insurance policies will cover you financially for these damages, but depending on where you live, your policy may require separate deductibles for wind or hail. The damages from a tornado can also include floods. Flood damage is not covered under any standard homeowners insurance policies, so purchasing an additional policy would be required to protect your home from these damages. Like tornadoes, damages caused by hurricanes are usually covered. These damages are typically limited to those caused by winds or fallen debris, and not flood damage. Fire If fire causes damage to your home or property, most policies will cover that damage. Restrictions aren’t common in regards to fire, but can be made in areas where wildfires are more likely to occur, or if the fire was set intentionally. This is something to take into account in Minnesota, where wildfires can be common. Extreme Cold Extreme cold isn’t unusual in Minnesota, where winters can be harsh and freezing. If a pipe bursts due to cold weather, the damages that water causes will most likely be protected. Damages from the weight of snow or ice will usually be covered as well. If snowmelt or the pipe bursting results in a flood, the flood damages will not be protected by insurance. Lightning Lightning strikes can cause many types of damage. Fire, explosions, or power surges can all be a result of lightning striking your home. Most homeowner’s insurance will cover these damages, even if the lightning doesn’t strike your home directly. For example, if lightning strikes a tree next to your home and the tree falls causing damage, your insurance will most likely cover it. Volcanoes For many people, this natural disaster doesn’t apply to their property at all. But for those who live in close proximity to a volcano, this is something they have to think about. A volcanic eruption causes ash, dust, and lava flow. Insurance will usually cover damages from these, but may not cover damages from shockwaves or earthquakes without additional policies. What Isn’t Covered? While many natural disasters are covered by your insurance policy, there are a few that aren’t. These natural disasters can be protected by purchasing additional policies, but aren’t included in the basic insurance. These are some natural disasters that won’t be protected. Earthquakes More than half of the states in the U.S. are at risk of earthquakes and the damage they cause. While they aren’t covered in any insurance policy, you can purchase an earthquake specific policy. This may be a good idea if you live close to a fault line. Floods Flooding from rain, burst pipes, or similar problems isn’t covered in your usual basic homeowner’s insurance policy. The cost of additional flood insurance varies based on where you live and how common flooding is in that area.Floods are quite common in Minnesota, so an additional policy would most likely be useful. Coverage costs range from $600 to even more than $1,200 per year. Tsunamis Tsunamis are giant waves that are typically created by an earthquake or volcanic eruption deep in the ocean. These disasters travel inland, damaging homes and various buildings. Flooding is a major result of tsunamis, and like stated above, aren’t covered by insurance. If you live near the coast, consider purchasing additional flooding coverage to protect your property. And, despite what you may think, our local Lake Superior does, in fact, experience its own form of tsunamis (called meteotsunamis ). Rapid Restoration is Here to Help!
