What to do if you feel cold air around your window frames after installation? ❄️

You’ve just replaced your windows and expected warmth, but suddenly there’s a cold draft? It happens! Usually, it’s because of small gaps or not enough sealing. ☝🏻After installation, check your windows carefully and don’t hesitate to ask the installers how to take care of them to keep the cold out.

Have you noticed black spots around your windows? It’s not just dirt — it’s dangerous mold!
It doesn’t just spoil the look — it harms your health, causing allergies, breathing irritation, and worsening asthma. Mold often appears because of poor window sealing, which traps moisture inside. ☝🏻 If you see condensation, smell mustiness, or notice dampness — it’s a sign to check your windows.
✅ Modern windows with good insulation solve this problem and keep your home comfortable and healthy.

Yes, yes — neighbors said patio doors are a bad idea for Boston winters.

But a family from Brookline had always dreamed of them and finally decided to install a set.

So what happened next?👇 Modern patio doors come with energy-efficient double or triple-pane glass and special coatings that keep the warmth inside. They’re also built with high-quality seals and airtight frames that block out cold air and drafts.

Now their home feels bright, warm, and cozy — and even their pets love sitting by the doors, watching the garden. 🌿

One old or poorly sealed window can leak around 10–15% of the heat in a room. Sounds small, right?

But in a house with 3–6 windows, the losses add up, and in a big home with 10–30 windows, it can cost hundreds of dollars a monthon heating. Heat loss depends on the number of windows, their condition, and how well they’re sealed — and this is exactly where you can save.

Proper installation and sealing of every window can really save both heat and money.

Can you install a window yourself?

Many people ask if they can install a window themselves. It seems easy, right? ❗️But here’s the truth: every window is different. One might not close properly, another could have tricky spots hidden from view. Without the right tools — levels, shims, drills, insulation foam, sealants, and measuring equipment — you’ll run into problems fast.

☝🏻Every detail matters, and missing even one can ruin the installation. If you’ve never done this before and you’re not a professional, “just putting in a window” is a lot harder than it looks. Trust me, some windows have a story of their own.

Thinking about just replacing the glass? Check a few more things first — it’s important.👇

❗️First — feel a small draft around the frame? That’s warm air escaping. Second — see condensation inside the frame, not on the glass? That means the problem’s deeper than a crack. And third — if the frame sticks, squeaks, or doesn’t close right — that’s another sign.

It might not look like a big deal,
but new glass alone won’t fix it without a new frame.
