Window and Door FAQ for McDonough, GA
Straight answers about home windows and doors in Henry County: what the work costs, which office permits it, what the Georgia energy numbers mean and where the local rules bite. Every figure here carries its source.
What is the average cost to install a replacement window?
Published Georgia figures for one installed window run from about $400 to $2,700, and most standard vinyl double-hung units land between $575 and $1,100. Modernize puts a basic window at $575 to $1,000, mid-range at $825 to $1,300 and high-end at $1,250 to $2,700 (updated August 27, 2026). Homewyse models $632 to $967 per window (May 2026). HomeScore's Georgia page starts vinyl at $400 to $700 installed.
What is the average cost to replace windows in Georgia?
For a whole house, plan on $6,000 to $16,000 for 10 to 15 windows, which is Modernize's own Georgia figure (August 27, 2026). PermitDeck's Georgia model puts a project at $3,514 to $7,594 with an average of $5,256. Five real Home Depot jobs in the 30252 and 30253 ZIP codes ran from $3,523 for 4 windows up to $61,138 for 36.
Who has the best prices for window replacement?
Nobody can answer that without quotes, because not one of the four national brands advertising in McDonough publishes a window price. Champion's own pricing page gives an industry range of $600 to $4,200 for a vinyl replacement window rather than its own number. The way to find out is to put the same scope in front of two or three installers and compare written quotes line by line.
What is the cheapest time of year to replace windows?
Late fall and winter are usually the quietest stretch for installers in this part of Georgia, which is when scheduling is easiest and promotions tend to appear. No local source publishes a seasonal discount figure, so treat timing as a scheduling advantage rather than a guaranteed price cut. Manufacturer promotions run year round.
How much should I budget for replacing my windows?
Count your windows and multiply by $575 to $1,100 for standard vinyl double-hung units, then add for anything unusual. Odd shapes, bays, second-story work, full-frame replacement and rotted sills all push past that. Modernize notes that materials are about two thirds of the total and labor about one third.
How much does it cost to replace windows on a 2000 sq ft house?
A 2,000 square foot house typically has somewhere between 15 and 20 windows, which puts it in Modernize's $6,000 to $16,000 whole-house band and often above it. The real Home Depot record closest to that size is a 15-window job in 30253 at $15,360, which works out to about $1,024 a window.
Is it cheaper to buy windows and have someone install them?
On paper yes, in practice it is risky. Materials are roughly two thirds of the job cost (Modernize), so supplying your own units looks like a saving, but a window ordered a quarter inch wrong is your problem, and most installers will not warrant their labor on glass they did not supply. Measuring is the part people get wrong.
How much does a front door replacement cost in McDonough?
Installed entry doors run about $850 to $6,200 depending on material, with steel at $850 to $3,000, fiberglass at $1,200 to $5,500 and wood at $1,800 to $8,000 or more (RemodelingExpense, June 26, 2026). Sidelights add $1,000 to $5,000 or more. The door itself at the McDonough big-box stores runs $169 for a primed steel slab up to $2,364 for a fiberglass prehung unit.

Do I need a permit to replace a window in McDonough or Henry County?
Both the City of McDonough and unincorporated Henry County enforce the Georgia State Minimum Standard Codes. Those codes require a permit to construct, enlarge, alter, repair, move or demolish a building, and their list of work exempt from a permit does not name windows or doors. City permits: 678-782-6224. Henry County: 770-288-6051.

What U-factor and SHGC do windows need in Henry County?
Henry County sits in Climate Zone 3, where the Georgia-amended energy code caps windows at a 0.35 U-factor and a 0.27 solar heat gain coefficient, with skylights at 0.55. The 0.27 SHGC is Georgia's own amendment rather than the base national figure, and lower is better on both numbers in a climate with long, hot summers.

What makes a bedroom window an escape opening?
Four numbers: at least 5.7 square feet of net clear opening, at least 24 inches of clear height, at least 20 inches of clear width, and a sill no more than 44 inches above the finished floor. A grade-floor or below-grade opening can drop to 5.0 square feet. Every sleeping room needs one, and it has to open from inside without a key or tool.
Does this site handle vehicle glass?
No. This is house windows and house doors only: sashes, frames, glass units, entry doors, patio doors, storm doors and interior doors. Searches around McDonough mix home window work with vehicle glass shops, so if you landed here looking for a car, you want a different kind of business entirely.
How long does a whole-house window job take?
Days rather than weeks for the fitting, once the units arrive. Insert replacement runs roughly an hour or two per opening, so a 10 to 15 window house is usually a day or two of work. The long part is manufacturing, because replacement windows are made to your measurements rather than pulled off a shelf.

What is the difference between insert and full-frame replacement?
Insert replacement sets a new unit inside the existing frame and leaves your trim alone. Full-frame takes the frame, sill and trim out back to the rough opening so the flashing can be redone. Insert is cheaper and quicker and loses a little glass area; full-frame is what rot or a change in opening size requires.
Can one fogged window be fixed without replacing it?
Usually, by fitting a new insulated glass unit into the existing sash. Fog between the panes means the seal around that unit has failed. Drilling and venting the unit clears the view without restoring the seal or the gas fill, so ask which method a quote covers.
Which window style is best for a Georgia summer?
Style matters less than the glass package. The figure that controls summer heat is the solar heat gain coefficient, capped at 0.27 by the Georgia-amended code for Climate Zone 3, and lower is better. Casements seal tighter than sliding styles because the sash closes against a compression gasket, which helps with air leakage.
Is triple glazing worth paying for here?
Rarely. Triple glazing is a cold-climate answer that drives the U-factor down, and the Georgia problem is sun heat rather than heat loss. The same money usually does more on a low-E coating tuned for a low SHGC, a decent spacer and a careful installation.
Do I need a permit to replace a door?
Both the City of McDonough and Henry County enforce the Georgia State Minimum Standard Codes, which require a permit to alter or repair a building, and the exempt-work list in those codes does not name doors. City permits: 678-782-6224. Henry County: 770-288-6051. Widening an opening or adding sidelights is framing work, which the same codes cover.
What should I check before signing a window quote?
The manufacturer and series, the frame material, the glass package with its U-factor and SHGC, the installation method, what happens to interior and exterior trim, removal and disposal of the old units, who pulls the permit, and the cash total with any financing APR and term stated separately.
Are window warranties worth anything?
They are worth reading rather than assuming. Manufacturer warranties cover the product and usually have conditions on finish, painting and storm doors; installation warranties come from whoever fitted the window and are a separate thing. Ask for both in writing and check what transfers if you sell the house.

Can I replace windows myself?
It is legal to do work on your own home, and the measuring is where most people come unstuck: a replacement opening is measured in three widths and three heights, with the smallest of each used. A unit ordered a quarter inch too wide is not returnable, and materials are roughly two thirds of the job cost.
Does replacing windows add value to a house?
Partly. The Department of Energy's window guide puts the resale recovery at about 78 percent of the cost, which is a national figure rather than a Henry County one. It is a useful counterweight to both the claim that new windows pay for themselves and the assumption that they are money wasted.
What is a NFRC label and where is it?
It is the sticker on the glass of every new unit, and it carries the U-factor and SHGC along with visible transmittance and air leakage. Check it at delivery, before anyone peels it off, because afterwards you are relying on paperwork matching what was actually fitted.
Is there a tax credit or rebate for new windows in Georgia?
Not for a window-only job started now. The federal energy efficient home improvement credit closed to new work: the IRS says you can claim the credit for improvements made through December 31, 2025, so nothing installed after that date qualifies, and a 2025 installation is a question for a tax professional. Georgia's Home Energy Rebates are live but its own FAQ states that windows can be included only as part of a Home Efficiency Rebate project, and that replacing windows by itself will not achieve the required 20 percent energy savings needed to qualify. A whole-home efficiency package assessed by a program-approved contractor is the route there; we are not program-approved and cannot process a rebate.
