Buying Doors or Windows: What Questions Should I Ask Beforehand?

Before buying doors or windows, ask about materials, sizing, lead times, installation, cost, and warranties. The right questions help you avoid surprises, choose products that fit your home and budget, and work with a supplier who can actually help. A few minutes of conversation upfront can save weeks of frustration later.


Buying a new door or window sounds simple. Pick a style. Pay for it. Get it installed.

But once you start looking, it gets complicated fast. Materials, sizes, glass options, energy ratings, lead times, installation, and warranties. There is a lot to sort through.

The difference between a smooth project and a frustrating one often comes down to what you ask before you buy. The right questions help you understand what you are getting, avoid surprises, and find a supplier who will actually help you through the process.

Here are the questions that matter most.

What Questions Should I Ask About the Product Itself?

Start with the basics. Understanding the product helps you compare options and make a confident choice.

  • What material is best for my situation? Doors come in fiberglass, iron, wood, steel, and other materials. Windows come in vinyl, aluminum, and premium options. Each has trade-offs for durability, maintenance, energy efficiency, and cost. Ask what works best for your climate and your home.
  • What is the energy efficiency rating? Look for doors and windows with good insulation values. Ask about U-factor and R-value. In North Georgia, where summers are hot and winters can get cold, energy efficiency makes a real difference on your bills.
  • Is this a standard size or will it need to be custom? Standard sizes are faster and often less expensive. Custom sizes take longer and cost more, but they are sometimes the only option for older homes or non-standard openings.
  • What glass options are available? For doors with glass panels and for windows, ask about clear, privacy, decorative, and low-E options. Glass choice affects light, privacy, and energy performance.
  • What hardware is included? Some doors come with handles, locks, and hinges. Others do not. Make sure you know what is included and what you need to buy separately.

What Questions Should I Ask About Sizing and Fit?

Getting the size right is one of the most important parts of a door or window project. A mismeasure means delays, extra costs, or a product that does not fit.

How should I measure my opening? Ask the supplier for guidance. Measuring incorrectly is one of the most common mistakes homeowners make. If you are not confident, ask if someone can help or if the installer will measure before ordering.

What if my opening is not standard? Many older North Georgia homes have openings that do not match today’s standard sizes. Ask if custom sizing is available and how long it takes.

Can modifications be made if needed? Some suppliers can adjust doors on-site. This can save time compared to ordering a fully custom product from a factory.

What happens if the product does not fit? Ask about the return or exchange policy before you order. Knowing this upfront protects you if something goes wrong.

What Questions Should I Ask About Lead Times and Availability?

Timing matters. If you are in the middle of a remodel or need to replace a damaged door quickly, lead time can make or break your schedule.

  • Is this product in stock? Stock items can often be picked up the same day or within a few days. Special orders and custom products take longer.
  • What is the lead time for custom orders? Custom doors and windows can take 6 to 12 weeks or more. Plan accordingly and order early.
  • Can you help if my timeline changes? Projects shift. Ask if the supplier can hold products, adjust delivery dates, or help you find alternatives if something gets delayed.
  • How will I know when my order is ready? Ask how the supplier communicates about order status. You want to know when to expect your product without having to chase updates.

What Questions Should I Ask About Installation?

Even the best door or window will fail if it is installed poorly. Ask about installation before you buy, not after.

  • Do you offer installation or recommend installers? Some suppliers sell products only. Others can connect you with trained installers. At The Liquidators Company, we work with a network of installers who are trained on our products and can coordinate scheduling and delivery.
  • What does installation cost? Installation is usually separate from the product price. Get a quote before you commit so you know the full cost.
  • Who is responsible for the installation warranty? Product warranties and installation warranties are usually separate. Make sure you understand who covers what.
  • What prep work is needed before installation? Ask what you need to do before the installer arrives. This might include clearing the area, removing the old door or window, or making sure the opening is ready.

What Questions Should I Ask About Cost and Payment?

Price matters, but the lowest number is not always the best deal. Ask questions that help you understand the full picture.

  • What is included in the price? Make sure you know whether the quote includes hardware, glass, weatherstripping, and any other components. Ask about delivery fees, too.
  • Are there financing options? Some suppliers offer financing to help spread out the cost. Ask what programs are available and what the terms are.
  • How does this price compare to similar products? A good supplier will help you understand why products are priced differently. More expensive does not always mean better, and cheaper does not always mean worse.
  • Are there any additional costs I should expect? Ask about potential extras like custom sizing fees, modification charges, or installation add-ons. Surprises at the end of a project are never fun.

What Questions Should I Ask About Warranties?

A warranty protects your investment. But not all warranties are the same. Ask the right questions so you know what you are getting.

  • What does the product warranty cover? Ask specifically what is included. Some warranties cover defects only. Others cover more.
  • How long does the warranty last? Warranty length varies by product and material. Fiberglass doors and iron doors often have longer warranties than steel or wood.
  • Does the warranty transfer if I sell my home? This can add value if you plan to sell in the future.
  • Is proper installation required for the warranty to be valid? Many product warranties require professional installation. A bad install can void your coverage.
  • What is the process for making a warranty claim? Ask how claims are handled before you need to make one.

What Should I Do Next?

Buying doors or windows does not have to be stressful. The key is asking questions before you commit.

Write down what matters most to you. Is it energy efficiency? Durability? Staying on budget? Matching a specific style? Knowing your priorities helps you ask better questions and evaluate answers.

Then find a supplier who will take the time to answer them. A good supplier does not rush you or push you toward the most expensive option. They help you understand your choices so you can make a confident decision.

What questions should I ask before buying a new door?

Ask about the material and how it handles your climate, whether the size is standard or custom, what the lead time is, whether installation is available, and what the warranty covers. Also, ask about energy efficiency ratings and what hardware is included.

How do I know if I need a custom door or window?

If your opening is not a standard size or if you want a specific style, glass pattern, or configuration, you may need a custom product. A good supplier will measure your opening and tell you whether stock or custom is the better fit.

What should I ask about warranties when buying doors or windows?

Ask what the product warranty covers, how long it lasts, and whether it transfers if you sell your home. Also, ask if proper installation is required for the warranty to stay valid. If using an installer, ask about their labor warranty separately.
