Commercial Balcony & Deck Specialists · CSLB #1060736
The arches over Broadway say Climate Best by Government Test, and the numbers back them up: 21.6 days a year above 90°F and 1.8 nights below freezing, against 82 and 30 in the valley cities we also work. Nothing extreme ever happens to a balcony here. That is the slogan's promise and it is also the problem, because a climate that never does anything dramatic to your building never tells you anything about it either. Licensed CA contractor serving Downtown, Redwood Shores, Woodside Plaza, and Friendly Acres with SB 721 and SB 326 inspections, deck repair, and waterproofing.

06 / Services
In 1925 the Chamber of Commerce ran a slogan contest and its own president won ten dollars for "By Government Test, Our Climate is Best". Historians are fairly sure he made the government test up, and that he was thinking of a friend who rode a bicycle and kept his own weather notes. The slogan went on the arches anyway - and here is the awkward part: it is basically right. The National Weather Service, which keeps an office in this city, records 21.6 days a year over 90°F and 1.8 nights at freezing. Nothing here is extreme. Nothing is dry either. Here's where we lead.

09 / Client Voices
Forty years and the building has never given us a single dramatic day. That was our whole argument for not looking. D&B turned it around on us in one sentence and they were right - we had no information, we had an absence of incidents. Two balconies needed doing.
Twenty inches of rain a year sounds like nothing until someone points out it has been twenty inches every year since 1988 and the summers here never get hot enough to dry anything properly. Nobody had ever explained the arithmetic to us.
We're on the old salt flats and the ground here is what it is. They knew that before we told them, and they looked at the bases first. That is not a thing you get from a firm reading off a checklist.
10 / Local Context
This is the only city we write about whose official municipal slogan is a weather claim, and it is worth telling the story properly because the punchline matters. In 1925 the Chamber of Commerce and the Real Estate Board ran a contest for a slogan; Wilbur H. Doxsee won ten dollars for "By Government Test, Our Climate is Best", shortened to what is on the arches today. Doxsee was the Chamber's own president. The historical marker downtown concedes that the origin of the test is uncertain; the leading theory involves German consular agents in 1912, and the local historian's view is that Doxsee essentially made it up, borrowing from a friend named Henry Finkler who cycled around the hills recording temperatures and rainfall for his own amusement and concluded that the world had exactly three perfect climates – the Canary Islands, the Mediterranean coast of Africa, and everything within twenty miles of Redwood City. Now the awkward part: he was not wrong. The National Weather Service, which keeps both a forecast centre and a cooperative office in this city, records the normal annual precipitation at 20.56 inches, an average of 21.6 days a year with highs at or above 90°F, 2.8 days at or above 100°F, and 1.8 nights at or below freezing. For comparison, the valley cities we also work in run 65 to 82 days over 90°F and up to thirty nights below freezing. Redwood City genuinely is mild. And that is precisely the problem on this page. Twenty inches of rain a year is not a small amount of water – it is more than Sacramento gets. The climate is Csb, warm-summer, which means the summers never get hot enough to dry a framing cavity out properly. So the moisture is here and the drying is not, and decay proceeds exactly as it would anywhere – except that nothing dramatic ever happens to prompt anybody to check. There is no January the roof came off, no August the coating split. There is just twenty inches a year, every year, and a building that never complains.
Redwood City incorporated in 1867 – the first city in San Mateo County and the oldest on the Peninsula – and has been the county seat since the county was created in 1856. It started as a lumber port on Redwood Creek and still runs the only deepwater port on the bay south of San Francisco. Downtown carries that history; the county's 1910 courthouse is now the history museum. The other half of the city is a different proposition entirely. Redwood Shores, out past Highway 101, is roughly two thousand acres of former tidal marsh that the Leslie Salt Company diked in 1928 and used as salt brine evaporation ponds, then built out as a master-planned waterfront community from the 1970s. It is a large body of condominium and association stock on made ground behind earthen dikes, and it is SB 326 Inspection territory on the nine-year cycle. Between the two sits the ordinary rental stock of a Peninsula city – Friendly Acres, Woodside Plaza, Centennial, Stambaugh-Heller – which is SB 721 Inspection on six. Different eras, different ground, same statute, and one thing in common: none of it has ever been through a weather event severe enough to make anyone open it up.
Downtown, Broadway, Centennial, Stambaugh-Heller, Edgewood, Mount Carmel, Central, Palm, Canyon, Eagle Hill, Roosevelt, Woodside Plaza, Farm Hills, Friendly Acres, Redwood Village, Redwood Oaks, and Redwood Shores. ZIP codes 94061, 94062, 94063 and 94065.
In Redwood City we most often address: (1) decay that has taken thirty years to get where it is, because a mild climate does not stop rot – it only stops the rot from being interesting; (2) buildings whose owners have mistaken an absence of incidents for evidence of soundness, which is the single most common reasoning error we meet in this city and the hardest to argue with, because on the surface it looks like a track record; (3) first-generation membranes on Redwood Shores stock now decades into service on made ground, where the base of a post and the underside of a connection deserve looking at before the walking surface does; (4) nothing at all on the surface – no stain, no sag, no tell – which is why in a city where the weather will never do it for you, Annual Maintenance Plans and a scheduled look are the only mechanism that exists. See our Inspections page for what that actually involves.

12 / Common Questions
$400-$800 per building for a 3-8 unit property. Redwood City splits on ground rather than on age: a downtown building and a Redwood Shores building on diked former salt ponds are the same statute and not the same walk, because on made ground we start at the bases and the connections rather than at the deck. The site visit that tells us which one you own is free.
It is the most persuasive-sounding evidence there is, and in this city it is close to worthless - which is an uncomfortable thing to be told and the reason we say it early. Look at what the National Weather Service actually records here: 21.6 days a year over 90°F, 1.8 nights at freezing, and 20.56 inches of rain. Compare that with the valley towns we also work, where 65 to 82 days over 90°F cook a coating until it splits and thirty freezing nights lever a joint open. In those places the building tells you something every single year, and an owner who has had no trouble in forty years has genuinely learned something. Here, nothing happens. Ever. Not because your building is sound but because the climate is polite. Meanwhile 20.56 inches a year is more rain than Sacramento gets, and a warm-summer classification means the framing never bakes dry the way an inland assembly does. Moisture without drying is the condition decay wants; the mildness just removes the alarm. Forty uneventful years in Redwood City is not a track record. It is forty years of no data.
Mostly, and the way it got there is worth knowing. It came out of a 1925 slogan contest run by the Chamber of Commerce and the Real Estate Board, which was won - for ten dollars - by the Chamber's own president, Wilbur Doxsee. The city's historical marker admits the origin of the "government test" is uncertain. The leading theory credits German consular agents gathering meteorological data in 1912; the local historian's account is that Doxsee took the idea from a friend, an amateur meteorologist named Henry Finkler, who recorded the weather on his bike rides and decided there were three perfect climates on earth and that one of them was here. So the science is thin and the marketing was a stitch-up. And the numbers still say he was basically right. We like the story because it is exactly what this page is about: the climate really is the best by any reasonable test, and a balcony does not care how pleasant the weather is. It cares whether it is wet and whether it dries. Here it is the first and not really the second.
Cosmetic work and straight recoating generally don't. Structural work does, through the City of Redwood City. Worth flagging for Redwood Shores in particular: that community sits on roughly two thousand acres of former tidal marsh diked off by the Leslie Salt Company in 1928 and used for salt evaporation before it was built out from the 1970s. Made ground behaves differently from the Peninsula hillsides, and a scope that involves footings, posts or anything below the deck is worth having someone look at who knows that before they quote it rather than after.
Ownership structure decides it, not the building. HOA-governed condominiums are SB 326, nine-year cycle. Non-HOA rental buildings of three or more units are SB 721, six-year cycle. Redwood City splits neatly by geography: Redwood Shores is largely association stock and therefore SB 326, while the older neighbourhoods on the mainland side of 101 carry most of the SB 721 rental inventory. A detached single-family association with no elevated elements is outside both laws. We'll tell you which of the three you are before you spend anything.
Callback the same business day, on-site within 48 hours. Redwood City is 109 miles from our North Highlands yard, so we are honest that we are not the crew for something in the next hour. We schedule the Peninsula in blocks and bring the full crew and materials in one mobilisation, which for a multi-building association is one disruption instead of four. Genuine safety issues we move on immediately regardless - though it is fair to say that in a city like this one, the finding that matters is almost never the one somebody phoned in about.
