Learn MoreWe keep the process straightforward. You will know what to expect at every step.
Reach out by phone or contact form. We respond within 1 business day. On that first call, tell us about your home, the space you have in mind, and what you want to use the room for. No commitment at this stage, just a conversation to see if we are the right fit.
We visit your home, measure the space, check your foundation and exterior wall, and assess any site-specific factors. San Bruno homes built in the 1950s and 1960s have quirks a good contractor spots early. After the visit, you receive a written proposal with a clear scope and total cost before permits are filed.
Once you sign and permits are approved, we begin. Foundation and framing are done first, then glass, roofing, and any electrical or HVAC connections. City inspectors sign off at every required stage. We do a final walkthrough with you before we leave, and you keep copies of all permits.
We are a licensed Sunroom Contractor in California, carrying full general liability and workers compensation on every project. Our license is on file with the California Contractors State License Board and available on request.
We visit your home, measure the space, and hand you a written estimate before anything is signed. No vague ballpark numbers over the phone, no surprise line items after work starts. What we quote is what you pay.
We have been building sunrooms and enclosures on the San Francisco Peninsula since 2020. We know mid-century Bay Area homes, the local permit process, and the coastal climate challenges that out-of-area contractors miss.
We submit all permit applications to the City of San Bruno's Community Development Department, coordinate every city inspection, and give you copies of all sign-offs when the job is done. Your addition is fully on record.

"We finally have a room we can use when the fog rolls in. The team handled the permit process with the city and kept us updated the whole way through. The four-season room has become our favorite part of the house."
Maria R., San Bruno - Four Season Sunrooms
"Our patio used to sit empty from October through May. The patio enclosure changed that completely. They matched the roofline to our existing house so well that guests think it was always there."
James T., Millbrae - Patio Enclosures
"I was nervous about the whole process but the written estimate had every line item, the timeline they gave us was accurate, and the sunroom addition came in on budget. It added real space to a home we were running out of room in."

Thinking about a sunroom or enclosure? Here are six things that matter before you call a contractor.
A three-season room skips insulation and HVAC, making it noticeably cooler in winter. In San Bruno, where temperatures rarely dip below the mid-40s, a three-season build works well for most of the year. If you want comfort during foggy summer mornings or cold January nights, a four-season room is worth the extra cost.
Yes, in nearly every case. California treats any attached room addition as a structural change requiring a building permit. The City of San Bruno reviews plans and inspects the work. Unpermitted additions complicate home sales and can affect insurance claims. The National Association of Home Builders notes that permitted additions protect both safety and resale value at nahb.org.
The noisiest phase is foundation work, typically lasting a few days. Framing, glass installation, and finishing are quieter and happen mostly outside your living space. You will not need to leave your home. Expect workers on your property most weekdays for four to twelve weeks depending on project size.
If you already have a covered patio with a solid slab, enclosing it costs significantly less than building a sunroom from scratch. A patio enclosure adds glass panels, a sealed roof, and doors to what you already have. The result is a protected room that uses existing square footage more efficiently.
The persistent marine fog keeps humidity elevated even in dry months. Frames, glass seals, and roofing materials need to resist moisture and salt air. Aluminum framing and insulated glass are the standard specification for Bay Area projects because they hold up in damp coastal conditions better than wood-framed alternatives.
Ask for the contractor's California license number and verify it at the California Contractors State License Board (cslb.ca.gov). Confirm they will pull permits and handle all inspections. Get a written estimate with itemized costs before signing. Ask to see a completed project in person. A confident, experienced contractor welcomes every one of these requests.

We hold a valid California contractor license issued by the California Contractors State License Board. Every project we take on is permitted, inspected, and fully documented before we consider it complete.
Over the years we have completed sunroom additions, patio enclosures, all-season rooms, and conversion projects across 12 Bay Area communities. We know the mid-century housing stock in this area, the city permit offices, and the coastal climate challenges that make getting this work right matter more here than in most places. Learn more about us.
A contractor should inspect the slab for thickness, levelness, and signs of cracking or settling before quoting. Many San Bruno patio slabs were poured in the 1950s and may need reinforcement. The California Contractors State License Board (cslb.ca.gov) keeps a list of licensed contractors who can perform this assessment.
Unpermitted additions create problems at sale time. Bay Area buyers and their lenders routinely flag unpermitted work during escrow, and sellers are often required to remove or legalize the addition before closing. Insurance claims can also be affected. The short-term savings are rarely worth the long-term exposure.
A fully permitted, insulated sunroom that meets California's energy standards and is connected to the home's heating and cooling can be counted as conditioned living space. A screened or three-season room typically is not. Your contractor should be clear about this distinction upfront so your expectations match reality.

San Bruno is a city of about 45,000 people on the San Francisco Peninsula, just south of the city and north of the San Mateo County border. Most of the housing here was built between the 1940s and 1970s, giving the city a distinct mid-century character that longtime residents take pride in. Homes in San Bruno tend to have small to mid-size lots, stucco exteriors, and backyards that sit unused for much of the year because of the coastal fog that rolls in from the Pacific most mornings.
San Bruno sits adjacent to San Francisco International Airport, and its neighborhoods range from the flat streets near Tanforan Shopping Center to the hillside areas with views toward San Bruno Mountain State and County Park. The Crestmoor neighborhood, rebuilt after the 2010 gas pipeline explosion, has newer homes sitting next to original postwar construction. Whether your home is in Crestmoor or on a street that has not changed since the Eisenhower administration, we have worked on homes like yours.
San Bruno homeowners are invested in their properties. The median home value here is above $900,000, and most homes are owner-occupied by people who intend to stay. When you hire San Bruno Sunrooms & Patios, you are working with a contractor who understands what these homes are built like, how the city permit office works, and why getting this addition right matters in a real estate market this competitive. We are not passing through, and we stand behind every room we build.
