Money, Taxes and Insurance
01
Will New Windows Raise Your Property Taxes in LA County?
No, not for a like-for-like swap. The Los Angeles County Assessor lists “replacing or repairing doors, windows, fences or decks” as work it does not reassess.
Adding square footage is different. New windows that come with a room addition, an ADU or a garage conversion are part of new construction the Assessor can reassess.
02
Can New Windows Lower Your Home Insurance Premium?
They can help. California’s Safer from Wildfires rules list upgraded windows as one of the home-level steps that count toward an insurance discount, and multi-pane glass or added shutters both qualify (California Department of Insurance).
The discount amount is set by each insurer. After the install, send your insurer the final permit and the window invoice, and ask what the upgrade is worth on your policy.
03
Are “Free Window” Programs Real in Los Angeles?
Free upgrades exist, but free whole-house windows are rare. LADWP’s Home Energy Improvement Program gives eligible customers free energy and water upgrades picked after a home assessment, and its program page doesn’t list new windows among them.
Ads that promise free windows are sales leads for a company visit. For real money back, see the rebate and tax credit answer on our homepage.
Hiring and Quotes
01
How Many Window Quotes Should You Get?
Three. The Contractors State License Board (CSLB) tells homeowners to get at least three written bids and to compare them on the same plans and scope of work.
The CSLB also warns against any bid far lower than the others. A low number can leave out the permit, stucco patching or removal of the old frames, so compare line by line.
02
What Are Red Flags in a Window Sales Pitch?
Watch for these signs before you sign:
- A price that expires tonight. A fair quote holds long enough for you to compare it with two others.
- One lump sum. Every window should have its own price, brand and glass listed.
- A big deposit. California caps the down payment at $1,000 or 10% of the price, whichever is less.
- Cash only. The CSLB advises against paying in cash.
- No salesperson registration. Salespeople for home improvement companies must register with the CSLB, so ask to see the card.
Our process page covers the contract and your right to cancel.
03
Can You Buy Windows Yourself and Hire Someone to Install Them?
Yes, but you carry more risk. If a window arrives the wrong size, you own the problem, and the installer’s labor warranty won’t cover a defect in a product you bought.
Your windows still have to meet Title 24, which means a U-factor of 0.30 or lower for most of Los Angeles, and the city inspector checks the label. See types of replacement windows before you order.
04
Do You Tip Window Installers?
A tip isn’t expected, since the contractor’s price covers the crew’s labor. Cold water on a hot day and a thank-you are common.
If the crew did good work, a written review that names the contractor helps them more than cash.
Planning Around Your Home
01
Should You Replace Windows Before or After Painting?
Before. Installing windows can scuff trim and leave stucco patches that need paint, so painting last covers both jobs in one pass.
The same goes for a kitchen or bath remodel. Set the new window first, then finish tile and cabinets around the final opening size.
02
Do New Windows Keep Out Wildfire Smoke?
They help, but windows don’t filter air. New windows seal tighter than old aluminum sliders, so less smoke leaks in around the frames when they’re shut.
On smoke days, the EPA advises keeping windows and doors closed and running a portable air cleaner or a high-efficiency HVAC filter. Tight windows make that filter work on less outside air.
03
Can Windows Be Installed in the Rain?
In light rain, a retrofit install can go on because installers open one window at a time and close it the same day. In heavy rain, contractors reschedule.
Sealant and flashing tape makers list the surface and temperature limits on their labels. Water on the frame during sealing is what leads to leaks later.
04
Do You Need to Call Your Alarm Company First?
Yes, if your windows have alarm sensors. Window installers don’t wire alarm systems, so old sensors come off with the old frames.
Book your alarm company for the day after the install. They can move the sensors to the new frames or switch to wireless ones.
After the Install
01
Why Do New Windows Fog Up on the Outside in the Morning?
Your new glass is keeping the heat inside. Natural Resources Canada explains that low-E coatings reduce heat loss, and on a cool, calm, humid night, condensation can form on the outside of the glass around sunrise (Natural Resources Canada).
It burns off as the sun warms the glass. Fog between the two panes is a different problem, covered on our foggy window repair page.
02
When Can You Peel the Stickers Off New Windows?
After the final inspection. The inspector checks the NFRC label on each window for the U-factor and SHGC, so leave every sticker on until the permit is signed off.
Before you peel them, take a photo of each label. Utility rebates and future buyers can ask for proof of the ratings.
03
How Should You Care for New Windows in the First Few Weeks?
Let the caulk cure before you wash the frames, and check the tube or the contractor’s paperwork for the cure time. Clean vinyl and fiberglass frames with mild soap and water, not solvents or scrub pads.
Open and close every window and lock a few times in the first week. If a sash sticks or a lock won’t line up, call the contractor while the crew still has your job on file.
04
Will New Windows Make Your House Feel Stuffy?
They can, because new windows let in far less outside air. That tighter seal is what keeps heat and noise out.
Run your kitchen and bathroom fans while cooking and showering, and open a window or two on mild days. For moisture on the inside of the glass, see our foggy window repair page.
