1.What’s the best window type for Burlington’s cold winters?
Triple-pane with Low-E366 & argon gas for max insulation—reduces heat loss and noise from traffic while it block 98% of the UV Heat Rays in the Summer. Its a WIN-WIN!

2.How long does window or door installation take?
Typically 1–3 days for 10–15 windows; full home doors 1–2 days. We minimize disruption.

3.Who installs your products?

Actually, the owner Derrick with his crew installs all of the products. This stops any doubt and assures the client is in great hands from ordering to installation and after install service (if ever needed)

4.Do you serve Hamilton and Oakville?
Yes—full service across Burlington, Oakville, Milton, Hamilton, and surrounding GTA areas.

5.What if I’m not sure about steel vs fiberglass doors?

6. How do I know your reviews are real and not paid for?

All our reviews come straight from Google — real customers who’ve had windows, entry doors, or patio doors installed by us. We never pay for reviews or ask people to change their honest feedback. You can read every one directly on our Google Business Profile.

7. How many Google reviews does The Door Centre have?

As of 2026, we have over 50 five-star reviews on Google (and counting!). Clients consistently praise our clean installs, professional crews, and owner-supervised quality. Check the widget or click through to see the latest ones.

8. Do customers ever leave negative reviews?

We’re proud to have a near-perfect track record, but like any business, we’ve had the occasional concern. When that happens, we respond publicly, fix issues quickly, and learn from it. Transparency is important to us — that’s why we link directly to Google so you see everything.

9. What do people say most often about your installations?

The top comments we hear are: “spotless cleanup,” “professional and on time,” “Derrick and the team were great to work with,” and “the new windows/doors made a huge difference in comfort and noise.” Many mention how quiet the install was and how nice the home looked afterward.

10. Can I see before-and-after photos from real customers?

Yes! While privacy rules limit us from showing full home photos without permission, we share anonymized before-and-after shots of window replacements, entry door upgrades, and patio door installs in our showroom. Stop by 4280 Harvester Road #10, Burlington to see examples in person.

11. Why should I trust a family-owned company over a big chain?

We’ve been serving Burlington, Oakville, Hamilton, Milton, and the GTA since 1981. When you work with us, you’re dealing directly with owner Derrick Block who personally oversees every job—not a call center or subcontractor. Our reputation is everything to our family.

12. Do you have reviews on other sites besides Google?

Yes — you can also find us on HomeStars, Yelp, and Facebook. Most customers leave their feedback on Google because it’s the easiest and most visible, but we’re happy to share links to any platform you prefer.

13. What happens if I’m not 100% happy after installation?

We stand behind every project with our 10-year workmanship warranty (plus lifetime manufacturer coverage on Vinylbilt, Frank by Ostaco, and Vista products). If anything isn’t perfect, we make it right — no questions asked. Your satisfaction is our #1 goal.

14. How soon after install do customers usually leave a review?

Most leave one within a few days to a couple weeks, once they’ve lived with the new windows, doors, or patio for a bit. We gently follow up with a thank-you text asking for honest feedback — no pressure, just appreciation.

15. Can I contact past customers for references?

We’re happy to connect you with recent clients who’ve agreed to be references (with their permission, of course). Just ask during your free quote or showroom visit — many are glad to share their experience with neighbors in Burlington or Oakville.
