Good questions.
Clear answers.
Every home is different. A free consultation is the best way to get answers specific to your doorway.
Talk to a door specialistHow much does entry door replacement cost?
The total depends on your door, glass, hardware and the work your opening needs. A free consultation helps you compare options and understand your project estimate.
Which ProVia door material is right for me?
Fiberglass offers woodgrain or smooth looks with low upkeep. Steel is another durable choice. Your consultant can help compare style, exposure, maintenance and budget.
How long does installation take?
Many standard entry door installations can be completed in a day. Preparation, opening changes and weather can affect the schedule; Nex-Gen will discuss your project before installation.
Can you change the size of my doorway?
A wider or taller entry may be possible. Nex-Gen will review the existing structure, required modifications and your preferred configuration before recommending a plan.
Do you also replace patio and storm doors?
Yes. Ask about hinged or sliding patio doors and ProVia storm doors when discussing your entry or exterior door project.
What warranty comes with my new door?
Coverage depends on the product. Ask about the manufacturer’s terms and Nex-Gen’s Peace of Mind Protection Warranty for eligible fiberglass products, including labor coverage and exclusions.
Can I ask about financing?
Yes. Your consultant can explain current payment and financing options, if available, along with eligibility and terms. Start with a clear estimate for the work you need.
