Your heating bill hits you every winter. January comes around, and it’s another $300 or $400 on the bill. It sucks. But here’s the thing – a lot of that money is literally going out the window.
Or through cracks around your doors. Or gaps you can’t even see inside your walls. Air sealing fixes this. It’s not fancy. It’s not complicated. You just seal up the holes.
What’s Actually Happening
Think about it like this. Your house isn’t a perfect box. There are gaps everywhere. Around the window frames. Around door frames. Where pipes come into the house. Electrical outlets. The corner where your attic door closes. Some of these gaps are tiny, but they add up fast.
In winter, warm air is constantly leaking out of these gaps. Your furnace heats the house to 70 degrees, and that warm air just floats right out. So your furnace kicks on again to reheat. And again. You’re literally heating the outside. Air sealing means you find these gaps and seal them up. Caulk. Weatherstripping. Foam. Whatever it takes. No more free ride for the cold air.
Why Ottawa Specifically
Ottawa gets cold. Really cold. Minus 20 degrees isn’t uncommon in January. When it’s that cold outside, even small leaks become a real problem. The difference between inside and outside is huge. That pressure pushes warm air right out through any opening.
That’s why people here see their heating bills spike. If you’re already paying $200 a month for heat and half of that is escaping through holes, that’s $100 you’re just throwing away. Every month. Every winter. Plus, there’s the comfort thing. Have you ever sat on the couch near a window and just felt that cold? That’s drafts. That’s air coming in. Air sealing stops that.
What Kind of Savings Are We Talking About
Depends on how bad your air leaks are. Some houses are tighter than others. But you’re looking at anywhere from 10 to 30 percent savings on heating costs. That’s nothing.
So if you’re spending $1500 total on heating over a winter, you could save $150 to $450. A basic air sealing job costs between $500 and $1500. Do the math – you’re looking at payback in a year or two. Then it’s all savings after that.
Where Do Leaks Actually Hide
Windows and doors are obvious. You can see those. But there’s a lot more going on. Check out your electrical outlets on outside walls. Put your hand near them on a cold day. Feel that? Cold air is coming right through. Gaps in the electrical box.
Where pipes come into your house – that’s usually a gap. Sometimes a big one. Where your plumbing and wires come through the foundation. The basement rim joist area. Your attic access hatch – that one’s usually terrible. You can feel cold air coming down from the attic whenever someone opens it. The thing is, you can’t see most of these. That’s why you need someone who knows what they’re looking for.
How This Actually Gets Done
A contractor comes out and walks around. They look at all the obvious spots. Then they do a blower door test if you want to get serious. It pressurizes your house so air leaks become super obvious. You can actually see where the problem areas are.
Once they know where the leaks are, they seal them. Small cracks get caulked. Around doors and windows, weatherstripping works. Bigger gaps get foam. Takes maybe half a day to a full day, depending on how many leaks you have. It’s not messy. It’s not loud. And you’ll feel the difference right away.
Why Not Just Do It Yourself
You can handle obvious gaps yourself. Grab some caulk and fill in cracks around your trim. That’s fine for small stuff. But for a real job, you need tools. A thermal camera shows you exactly where cold air is coming in. A blower door test actually pressurizes the house so leaks become visible. Most homeowners don’t have that equipment.
Plus, pros know which material to use where. Caulk vs foam vs weatherstripping. They know the details. They work in attics and crawl spaces that honestly aren’t fun. And they warrant their work.
Getting It Done in Ottawa
Call around. Most contractors offer free inspections. They’ll walk through your place and tell you what they find. Get a couple quotes so you know what to expect price-wise. Fall is the best time before winter hits, but honestly if your bills are high right now, just do it now.
Also check if there are any rebates. Hydro Ottawa sometimes has programs for energy efficiency stuff. Might save you some money on the job.
Real Talk
Your heating bill is high because you’re losing heat through gaps. Air sealing fixes that. It’s not magic. It’s just plugging holes. But it works. If your place feels drafty or your heating costs are out of control, call someone and get an inspection. Most will do it for free. Then you know what you’re dealing with. Stop throwing money away.
FAQs
How long does it last?
Caulk may be 5-10 years old. Weatherstripping lasts 3-5 years. Foam can last 20+ years. You might need touch-ups over time, but that first sealing job keeps working for a long time.
Will it affect my ventilation?
No. A pro knows the difference between intentional ventilation and accidental leaks. They seal the leaks, not your vents. Your home still gets fresh air.
Can I do some myself?
Yeah, for obvious stuff. Grab a caulk gun and go at it around visible gaps. For a thorough job though, hire someone.
How much does it cost?
Depends. Small job, maybe $500. A bigger place or more leaks could be $1000-$2000. Get some quotes and compare.
When should I do it?
Fall before winter is ideal. But if you’re struggling with heating bills in January, do it now. Any time works really.
My house is old. Does it help?
Yeah, actually more so. Older houses have way more leaks, usually. More gaps, more cracks. That’s where air sealing makes a real difference.
