Frequently Asked Questions

How long will it take to install my new windows?

Most window installation projects in Lakewood take just one to two days, depending on how many windows you’re replacing and the style you choose. Our team works efficiently and minimizes disruption to your home, ensuring the job is done right the first time — without cutting corners.

Can I replace my windows in the winter months?

Yes — we perform window replacements year-round, including in winter. Our experienced installers use protective barriers and efficient techniques to minimize heat loss and exposure during colder weather. Replacing drafty windows in winter can actually lead to immediate energy savings.

Will the quote I received change after you take the measurements?

In most cases, no. Once we provide an initial quote and complete your in-home measurement appointment, your pricing remains the same — unless you decide to change the scope or window type. We believe in transparent, honest pricing with no surprises.

How do I choose the right windows for my home?

Our experts will guide you through the selection process based on your goals — whether it’s energy efficiency, noise reduction, aesthetics, or budget. With a wide variety of styles, finishes, and glass options available, we help you make confident, informed decisions.

What signs indicate that my windows need to be replaced?

If you feel drafts, see condensation between panes, have trouble opening or closing windows, or notice visible damage like rotting or warping, it may be time for replacement. New windows can drastically improve comfort, curb appeal, and energy performance in your Lakewood home.
