How Much Does It Cost to Replace a Fiberglass Door?

Your front door isn’t something you replace every day.

But when it starts sticking, leaking air, or just looks outdated, you know it’s time.

Still, one big question stops a lot of homeowners from taking the next step:

“How much is this going to cost me?”

We get it. You don’t want vague answers. You want real numbers.

Here’s the short version:

• Basic fiberglass door: around $1,000 to $1,500
• Mid-range with glass inserts: $1,500 to $3,000
• High-end custom or double doors: $3,000 to $5,000+

Now, don’t panic.

Not every door will hit the high end. And not all low-cost doors are a good deal.

Let’s get into the numbers.

Why Homeowners Choose Fiberglass Doors

Fiberglass doors are popular. And for good reason.

They’re tough.

They hold up against cold, rain, and humidity; perfect for Toronto weather.

They don’t warp like wood. And they won’t rust like steel

Homeowners love them because they’re:

• Low-maintenance
• Energy-efficient
• Stylish (they can look like real wood)

At Delco Windows and Doors, we recommend fiberglass all the time. It’s the best mix of durability, style, and value for money.

Average Cost For Fiberglass Door Replacement

So what does a fiberglass door replacement actually cost?

Here’s a simple breakdown:

Those numbers include installation.

Keep in mind:

• Labor in Toronto usually runs $500 to $1,000
• The door itself can range from $600 to over $3,500, depending on the style and features
• Add-ons like smart locks, sidelites, or custom paint increase the price

What Affects the Final Price?

Why do some doors cost $1,200 while others hit $5,000+?

Here’s what changes the number:

1. Style & Features

• No-glass solid doors are cheaper
• Decorative glass and sidelights raise the price
• Smart lock compatibility adds more too

2. Size

• Standard sizes are most affordable
• Oversized or double doors cost more
• Adding side panels or transoms? More labor = more cost

3. Energy Efficiency

• Doors with higher R-values (more insulation) cost more—but save on bills
• ENERGY STAR®-rated doors are usually worth the investment

4. Hardware & Finishing

• Basic knobs are fine
• But stylish handles, multipoint locks, or digital keypads bump up your quote

5. Installation Complexity

• Replacing a door in an existing frame? Lower cost
• Need a full frame rebuild or structural adjustments? Add $300–$700+

6. Brand Quality

• Budget brands = lower up-front cost
• Premium brands = longer life, better finish

 At Delco, we’ll walk you through both options so you can decide what fits your home and budget best.

Is It Worth the Investment?

Short answer: Yes.

A quality fiberglass door replacement pays off in more ways than one.

Energy Savings

• Better insulation = lower heating and cooling bills
• In Toronto’s weather, that adds up fast

Boosted Curb Appeal

• A new front door can increase home value by up to 4%
• Great if you’re planning to sell—or just want a fresh look

Improved Security

• Modern doors come with stronger locks and better sealing
• Peace of mind for you and your family

More Comfort

• New doors block noise and drafts
• Your home feels quieter, warmer, and more secure

How to Get the Best Value

You don’t have to overspend to get a great door.

But you also don’t want to cut corners.

Here’s how to get the most out of your investment:

1. Get Multiple Quotes

• Compare materials, installation, and warranties
• Watch for hidden costs or “extras” that should be standard

2. Choose a Trusted Local Installer

• In Toronto, working with a local company like Delco Windows and Doors means:
  • Fair pricing
  • Familiarity with local building codes
  • Faster service

3. Look for Rebates or Seasonal Discounts

• Sometimes energy-efficient doors qualify for government rebates
• Ask if there are off-season install promos

4. Check the Warranty

• Good fiberglass doors offer 10–20 years
• A solid warranty tells you the product will last

5. Don’t Fall for the Cheapest Option

• Bargain installs often skip proper sealing, framing, or leveling
• That can lead to problems, and more costs, down the line

Real Talk: Repair or Replace?

This is one of the most common questions we get: do I really need a new door, or can this one be fixed?

In some cases, a simple repair is enough.

Here’s a quick guide to help you decide:

Go for a repair if:

• You just need new weatherstripping
• The hardware is loose or outdated
• There are small cosmetic issues (scratches, paint wear)

 → Typical repair cost: $100–$400

But when the problems are bigger:

• The door sticks, warps, or doesn’t close right
• You feel drafts, even after sealing
• There’s visible cracking, water damage, or soft spots
• Your door is over 15 years old

It's time to start thinking replacement. These issues usually point to deeper structural problems that a repair can’t solve.

→ Replacement cost: $1,500–$3,500 (average)

If you're unsure, that’s where we come in. At Delco Windows and Doors, we don’t push people into replacing if they don’t need to. We’ll take a look, explain what’s going on, and let you know what makes the most sense: repair or replace.
