Factors to Consider When Choosing a Company

When requesting quotes and evaluating window companies in Nanaimo, keep the following factors in mind:

  • Experience and Reputation - Choose an established company with proven expertise, high-quality products, and satisfied customers. Be wary of fly-by-night contractors.
  • Window Brands and Materials - Look for ENERGY STAR-rated vinyl or fiberglass windows from trusted brands like Centra, Milgard, JELD-WEN, etc.
  • Warranties - Select companies that offer at least 5 years on labor and 20+ years on materials. Lifetime warranties on windows are ideal.
  • Certifications - Search for LEED Gold or higher certification for the windows, and licensed installers.
  • Price and Value - Get multiple quotes to compare pricing. More expensive doesn’t always mean better quality. Seek the best value.
  • Local Service - Working with a Nanaimo-based company provides convenience and accountability for follow-up service calls.

Things to Avoid

Be cautious of the following red flags when selecting a window company:

  • Limited or non-existent warranties that don’t stand behind the products.
  • Bad reviews for poor workmanship, damaged property, or lack of follow-up service.
  • Cheapest price options that seem too good to be true. This can indicate low-quality products.
  • Companies that seem evasive about licensing, certifications, insurance coverage, or physical business addresses.

Doing your research helps avoid choosing the wrong company and ensures your window project or job goes smoothly.

Frequently Asked Questions

What are the most popular styles of replacement windows in Nanaimo?

How much do replacement windows cost in Nanaimo?

On average, expect to pay $600 - $1100 per window including professional window installation services. High-end custom windows can cost $1500 or more. Get quotes from multiple Nanaimo companies to find the best value.

Should I choose fiberglass or vinyl window frames?

Both materials offer durability and efficiency. Vinyl is more affordable, low-maintenance, and effective at insulating. Fibreglass is very strong, dent-resistant, and has a wood-like aesthetic. Choose based on the look, budget, and performance needs.

What’s the best way to save money on replacement windows?

Ordering windows and installation as a complete package deal can provide bundled pricing discounts. Buying during off-season months can also mean better deals and incentives from window companies.

How long does it take to install replacement windows in Nanaimo?

The project timeline varies based on house size and the number of windows. A typical window installation only takes 1-3 days. Larger custom jobs may require 1-2 weeks. Reputable companies should provide estimated timeframes.

What permits do I need for window replacement in Nanaimo?

If the window sizes and locations will stay the same, you likely don’t need a permit. Adding new windows or changing sizes usually requires a basic building permit from the city planning department.
