How much will new windows save me?

Homeowners replacing single-pane or failed units typically see a meaningful drop in summer cooling costs, plus a noticeable difference in comfort and outside noise.

How long does a full window replacement take?

Most homes are done in 1–3 days. We open, replace, and seal one opening at a time so your home is never left exposed.

Full-frame or insert replacement?

Inserts are faster and less invasive when the existing frame is sound. If there's rot or the frame is out of square, full-frame is the right call — we'll show you which you have.

Do you replace exterior doors too?

Yes — entry, patio, French, and storm doors, including custom sizing, sidelights, and hardware.

Are your estimates really free?

Yes. Every estimate is free, written, and completely no-obligation. We measure, review material options with you, and leave you with a clear number — there is never a pressure close.

Are you licensed and insured?

REN Specialists is fully licensed, bonded, and insured in Georgia. We're happy to provide certificates of insurance before work begins.

What parts of Metro Atlanta do you serve?

We serve homeowners across Metro Atlanta, including Marietta, Alpharetta, Roswell, Sandy Springs, Decatur, Smyrna, Kennesaw, Johns Creek, Dunwoody, Brookhaven, and surrounding communities.

About This Service

Comfort, quiet, and curb appeal — installed correctly

Old single-pane and failed double-pane windows leak conditioned air, fog up, and make rooms uncomfortable. Modern energy-efficient units cut noise, block UV, and noticeably reduce summer cooling bills in Atlanta.

Installation matters as much as the window. We flash, shim, insulate, and seal every opening so you don't trade a drafty window for a leaky one.
