The site from the customer’s side
What a San Mateo customer sees before calling
The median San Mateo house was built in 1965, so pages for repair, replacement and remodel should show work on a house of that age. Lithium Marketing designs WordPress sites around that: a page for the jobs you take on older homes, photographs of finished work and a call button that stays on screen.
New construction is a small share: 7.4% went up in 2010 or later, while 70.4% of the city’s homes were built before 1980. That makes repair and replacement the pages most San Mateo customers need, so the photos should show a house of that age and its finishes.
Searches before the call
What a customer searches before they call
Searches naming San Mateo for web design total 260 a month, so the city already has businesses shopping for a site. The harder question is what your own customers type. “Roofing company san mateo” draws 110 searches a month, so the page that wins the click shows finished roofs, not a stock photograph.
If a visitor opens your site on a phone, a page that takes seconds to load can lose them before the photos arrive. Lithium builds on WordPress with the images compressed, the forms short and the phone link working on every screen.

The San Mateo market
Old homes, new condos and the pages between
The median San Mateo home is worth $1,618,700, and the city has 42,641 housing units. At that value, the finished work is the proof, so the site should carry project photos, a named owner and a service list that matches the work.
Bay Meadows, the 83-acre development on San Mateo’s old racetrack site, brings hundreds of new residential units alongside offices and shops. A contractor who takes on new-build and condo work should give it a page of its own, with the finish work and the schedules that come with it.

Trades in San Mateo County
Galleries for project trades, buttons for repair trades
A remodeler sells a picture. San Mateo County has 520 residential remodelers, 214 new home builders and 146 painting contractors, and the site has to show finished work before the call. That means a page for each project type, before-and-after pairs and a line about what the crew did on the job.
A plumber sells an answer. If the pipe has already burst, the phone number, the service area and the hours do the work, and the photos can wait. Electrical contractors, 206 of them in the county, get the same kind of call for a panel or an outlet, so their site should lead with the services and the number.

The build
From kickoff to launch on a San Mateo site
Six to nine weeks from kickoff to launch, with the design reviewed on a phone and a desktop before the build.
1
Send the work you want more of
Job photos, the services you sell and the cities you cover come from you, and the copy gets written from them.
2
Look at it the way a customer will
The design starts on a phone screen, then moves to the desktop version, with the call button and quote form within reach.
3
Build and test everything
Forms, phone links and tracking get tested, and GA4 with call tracking goes in so the first calls can be measured.
4
Go live with the old links intact
Redirects go in for the pages that already have traffic, and a private Loom walkthrough shows you how to edit text and swap photos.

- Sub-2.5-second mobile load

Proof
A septic company’s site, search and ads
Byers Septic Service commissioned a site rebuild, SEO and Google Ads from Lithium, and the card shows what that work produced. Chris Martin of Mt. Hood Pro Painting is quoted beside it.
Septic“Ever since we've used Lithium Marketing, our phone has been ringing off the hook and we can hardly keep up with the leads we get from Google, Facebook or through our website. Most of our leads other than referrals are through Google and it's all because of Lithium Marketing.”

Websites for the cities along the Peninsula
Every site Lithium builds can carry a page for a nearby city, and the links below show how that looks for web design. The next level up is the Bay Area metro page, then the California page for the state.
Published price
The price of a San Mateo website build
$5,000
typical project
Larger sites get a fixed proposal after a 30-minute discovery call. Six to nine weeks from kickoff to launch. You own the domain, hosting account, WordPress install and content.
What makes a San Mateo website cost more?
Page count, mostly. A company with a dozen project types and a page for every city it serves needs more copy and more design work than a four-service contractor. When the build is larger than the typical one, you get a written price before any work starts.
Who holds the domain and the hosting account?
The business holds them. Domain, hosting, the WordPress install and every page and photo sit in accounts with your name on them, and the logins come to you at launch.
We already rank. Does a rebuild put that at risk?
Rankings can move, and a missing page is a common cause. Plan the redirects before launch, keep the pages that already have links, and watch Search Console for the first weeks. Nobody can guarantee the exact positions, and a careful move is how you protect what you have.
What if I do not like the design?
Say so at the review. The phone layout comes first, then the desktop version, and changes are made before the build starts. You see the call button, the quote form and the project photos in place, so you are reviewing a working page.
What should I have ready before the kickoff?
Photos of finished jobs, the services you sell, the cities you cover and a list of the pages you want. If you have an old site, its logins save time. The copy is written for you, so no writing is required on your side.
