Short answer: we tested 20 window and door company websites on a phone. Only 3 showed their main content in 2.5 seconds or less, which is Google’s line for a good load, and 12 took more than 10 seconds. 19 of 20 have a tap-to-call link, 18 have a quote or estimate button, 12 have a form on the homepage and 5 have chat. The window websites worth copying load fast, say “window replacement” and the city in the first line, and put the phone number and the quote one tap away.
Key takeaways
- 3 of 20 window company homepages loaded their main content in 2.5 seconds or less on a phone: Mr Windows Houston (1.0 s), A Pane in the Glass (2.3 s) and Foster Exteriors (2.3 s). The slowest took 42.2 seconds.
- The two fastest also have a form, tap-to-call and quote buttons, so speed and lead capture can go together.
- Most get the contact basics right: 19 of 20 have tap-to-call and 18 have a quote or estimate button.
- One homepage scored 12 out of 100 on Google’s test, the lowest of any site in this list.
- 8 of 20 homepages have no headline that says where the company works, and one of those has no headline at all.
How we tested these 20 window and door websites
Most “best window and door website design” lists judge sites by a desktop screenshot. Homeowners often shop for new windows on a phone, sometimes standing next to the drafty window, so we tested what they get. Every test ran on November 13, 2026.
- Speed: we ran each homepage through Google PageSpeed Insights on the mobile setting, once per site. We recorded the performance score (0 to 100) and how many seconds the main content took to show (Google calls this Largest Contentful Paint). Google counts 2.5 seconds or less as good. One test is a snapshot, and results move a little from run to run.
- Ways to reach them: we opened each homepage in Chrome and checked for a tap-to-call phone link, a form with a phone, email or message field, a chat widget, and a button that asks for a quote, an estimate or an appointment. This is a homepage check only. A phone number shown as plain text doesn’t count.
- The list: each site is the first local window company in Google’s results for “window replacement company” plus a city, in 20 cities across the country. We skipped directories, national brands and franchises, because their sites aren’t built by the local company. None is a Demand & Convert client.

The fastest window and door websites (under 2.5 seconds)
Three sites cleared Google’s bar. Two of them also carry every main way to get in touch except chat.
1. Mr Windows Houston
mrwindowshouston.com. Tested Nov 13, 2026: score 98, main content in 1.0 s, tap-to-call yes, form yes, chat no, quote button yes.
The fastest site in the test and the model to copy. The headline is simply “Window Replacement Houston,” the exact search a homeowner types. The phone number is linked 9 times, and the homepage has a form and 9 quote buttons.
2. A Pane in the Glass
mnwindows.com. Tested Nov 13, 2026: score 93, main content in 2.3 s, tap-to-call yes, form yes, chat no, quote button yes.
A Minneapolis company whose headline, “Residential window replacement service Minneapolis, MN,” names the customer, the service and the city. It has 3 forms and 18 quote buttons, the second most in the test, and still loads in 2.3 seconds.
3. Foster Exteriors
fosterexteriors.com. Tested Nov 13, 2026: score 89, main content in 2.3 s, tap-to-call yes, form no, chat no, quote button yes.
A fast Dallas homepage with the phone number linked 8 times. It’s the only site in the test with no H1 heading, so Google has to work out the page’s main topic from the title and body text instead.
Good, but slower on phones (2.5 to 10 seconds)
These five sites are within reach of a fast load. Only one of them has a form on the homepage.
4. The Glass Company
utahglasscompany.com. Tested Nov 13, 2026: score 88, main content in 4.0 s, tap-to-call yes, form no, chat yes, quote button no.
The fastest site in the test with chat. The headline, “Window Repair & Replacement in Salt Lake City, UT,” is clear. There’s no button that asks for a quote or estimate, so a visitor who doesn’t want to call or chat has no obvious next step.
5. Window & Door Store
thewindowdoorstore.com. Tested Nov 13, 2026: score 75, main content in 5.1 s, tap-to-call yes, form no, chat no, quote button yes.
“Nevada’s Premier Window and Door Replacement Company” names the state and both products. It has 4 call links and 7 quote buttons.
6. Ringer Windows
ringerwindows.com. Tested Nov 13, 2026: score 53, main content in 7.4 s, tap-to-call yes, form no, chat no, quote button yes.
An Austin company that makes its own windows in Taylor, Texas, and installs them, a strong reason to choose a local company. The headline doesn’t mention Austin, though.
7. STL Windows Direct
stlwindowsdirect.com. Tested Nov 13, 2026: score 61, main content in 8.0 s, tap-to-call yes, form yes, chat no, quote button yes.
“St Louis Window Replacement Company” leads the headline, followed by a price promise. It’s the only site in this group with a form on the homepage.
8. Window Fitters
windowfitters.com. Tested Nov 13, 2026: score 64, main content in 9.9 s, tap-to-call yes, form no, chat no, quote button yes.
A Nashville vinyl window company with the phone number linked 7 times. “Premium Windows for Your Nashville Home” names the product and the city in six words.
Strong companies, slow on phones (over 10 seconds)
More than half the list is here. Large window and home photos, sliders, review widgets and chat scripts all add time before a phone visitor sees anything.
9. Hall’s Window Center
hallswindowcenter.com. Tested Nov 13, 2026: score 41, main content in 14.0 s, tap-to-call yes, form no, chat no, quote button yes.
“The Most Trusted Window & Door Company in Sacramento County” is a clear headline. The page has a second H1 heading that reads “50% OFF,” which competes with it. A promotion works better as plain text or a banner.
10. New South Window Solutions
newsouthwindow.com. Tested Nov 13, 2026: score 42, main content in 14.7 s, tap-to-call yes, form yes, chat yes, quote button yes.
A Florida company covering replacement and hurricane impact windows, with 4 forms, chat and 19 quote buttons, the most in the test. The headline names the products but not the area, and the page takes almost 15 seconds to show on a phone.
11. Einar Johanson Window & Door
ejseattle.com. Tested Nov 13, 2026: score 65, main content in 16.4 s, tap-to-call yes, form no, chat no, quote button yes.
The headline is only the company name, so it doesn’t say where they work. A score of 65 looks fine, yet the main content took over 16 seconds, which is why the load time matters more than the score.
12. Weather Tite Windows
weathertitewindows.com. Tested Nov 13, 2026: score 55, main content in 17.1 s, tap-to-call yes, form yes, chat no, quote button yes.
An impact window and door company in Tampa Bay. “Impact Windows & Doors Built for Florida Living” appears twice on the page as two H1 headings. One is enough.
13. MWT Windows
mwtwindows.com. Tested Nov 13, 2026: score 36, main content in 17.2 s, tap-to-call yes, form no, chat no, quote button yes.
“Georgia’s Original Window People Serving Metro Atlanta for More Than Two Decades” names the area and the history, though it’s long for a phone screen. The phone number is linked once.
14. Brightside Windows
brightsidewindows.com. Tested Nov 13, 2026: score 37, main content in 17.7 s, tap-to-call yes, form yes, chat no, quote button yes.
A Portland company with 6 call links, 2 forms and 8 quote buttons. The headline, “Top-Quality Replacement Windows and Patio Doors by Brightside Windows,” names the products but not the city.
15. APCO
apco.com. Tested Nov 13, 2026: score 36, main content in 18.3 s, tap-to-call yes, form yes, chat yes, quote button no.
A Columbus exterior company whose headline lists windows, siding, gutters, doors and decking. It has 3 forms and chat, but no button that asks for a quote or estimate.
16. Discount Windows & Doors
discountwindows.com. Tested Nov 13, 2026: score 63, main content in 20.6 s, tap-to-call no, form yes, chat no, quote button yes.
A Denver company “Installing Energy Efficient Windows in Colorado Since 1984,” a line that appears twice as an H1, plus a third H1. It’s the only homepage in the test with no tap-to-call link.
17. Raleigh Window Company
raleighwindowcompany.com. Tested Nov 13, 2026: score 42, main content in 21.5 s, tap-to-call yes, form yes, chat no, quote button yes.
The company name says the city and the trade, and it doubles as the headline. The phone number is linked 8 times, and there are 2 forms.
18. Desert King Windows
desertkingwindows.com. Tested Nov 13, 2026: score 40, main content in 24.9 s, tap-to-call yes, form yes, chat yes, quote button yes.
Serves Phoenix and Las Vegas, and links its phone number 10 times, the most in the test. The headline is only the company name.
19. Newman Windows
newmanwindows.com. Tested Nov 13, 2026: score 12, main content in 25.1 s, tap-to-call yes, form yes, chat yes, quote button yes.
Serves San Diego and Orange County, with every contact option, including 4 forms and chat. Its score of 12 was the lowest in the test, so all that contact help sits behind a long wait.
20. Windura
windura.com. Tested Nov 13, 2026: score 50, main content in 42.2 s, tap-to-call yes, form yes, chat no, quote button yes.
A Kansas City and Overland Park company with 6 call links and a form. It was the slowest site in the test, and the headline, “Protect Your Home with Premium Windows & Doors,” doesn’t say where they work.
What the best window and door websites have in common
- The main content shows fast on a phone. Only 3 of 20 did it in 2.5 seconds, so a fast site stands out.
- A headline that says windows and where. “Window Replacement Houston” beats “Protect Your Home.” 12 of 20 did this.
- One clear H1. In our test, one homepage had no H1 and three had more than one.
- The phone number and the quote are one tap away. Most sites got this right: 19 had tap-to-call and 18 had a quote or estimate button.
- A short form near the top. 12 of 20 had one, including the two fastest sites.
- Photos and chat that don’t slow the first screen. 4 of the 5 sites with chat took 14.7 seconds or more. Compress photos and load chat after the main content.
Window and door website must-haves
New windows and doors are a big purchase, and homeowners usually compare a few companies before they book an in-home estimate. These pages and sections answer what they want to know:
- A free estimate: a short form and a tap-to-call number on every page.
- Products: a page each for window styles, entry doors, patio doors and, where it matters, impact windows.
- Brands and materials: the window brands and frame materials you install, explained in plain words.
- Cost and financing: honest price ranges and any financing you offer.
- Before and after photos: real local jobs with the city named.
- Warranty and installation: what’s covered, for how long, and who does the install.
- Service area: the cities and neighborhoods you serve.
- Reviews, ideally from Google.

How to test your own window and door website
- Open Google PageSpeed Insights, paste your homepage address, and run the test.
- Stay on the Mobile tab and find “Largest Contentful Paint.” 2.5 seconds or less is good. Look at this number, not just the score: one site in our test scored 65 but took over 16 seconds.
- Open your homepage on your own phone. Can you tap the phone number? Can you request an estimate in a few taps?
- Read your headline out loud. Does it say windows or doors and where you work?
Or run our free website speed test, which explains the results in plain English. If your site is fast but the phone still doesn’t ring, the problem is usually being found, not the site.

Frequently asked questions
What makes a good window and door website?
A good window and door website loads its main content in 2.5 seconds or less on a phone, says what you install and where in the headline, and has a tap-to-call number, a quote button and a short estimate form on the homepage. It also shows real local jobs, the brands you install, your warranty and reviews.
How fast should a window company website load?
The main content should show in 2.5 seconds or less on a phone, which is Google’s line for a good load. In our test of 20 window and door company homepages, only 3 met it, and 12 took longer than 10 seconds.
What pages should a window and door company website have?
A homepage, a page for each product such as replacement windows, entry doors, patio doors and impact windows, a cost and financing page, a page for each main area you serve, a gallery of local jobs, a warranty page, a reviews page, and an estimate page with a short form.
Should a window company website have a form or just a phone number?
Both. Some homeowners call right away, and others want to send a request after hours. 19 of the 20 homepages we tested had tap-to-call, but only 12 had a form. The two fastest sites in our test had both.
How do I check my window company website’s speed?
Put your homepage into Google PageSpeed Insights, keep the Mobile tab selected, and look at Largest Contentful Paint. You can also use our free website speed test, which explains the result in plain English.
