Commercial Balcony & Deck Specialists · CSLB #1060736
In 1945 the real estate industry told Henry Doelger not to build here. They called this place the Fog Gap. Eighty years earlier the fog had already driven the grain farmers off this land - it killed the crops, and the ones who stayed switched to dairy because grass does not mind. Doelger built 1,350 acres of housing in it anyway, and 40% of this city's stock predates 1950. Grass does not mind the fog. Wood does. Licensed CA contractor serving Westlake, Serramonte, Top of the Hill, and Original Daly City with SB 721 and SB 326 inspections, deck repair, and waterproofing.

Work executed by our in-house CSLB-licensed construction crew. Final walkthrough, photo documentation, warranty paperwork.
06 / Services
The historical record on this city's climate is not poetic, it is agricultural. Irish settlers took up farms here after 1853; within a decade several families had left because the fog got dense enough to kill their grain and potato crops. The ones who stayed switched to dairy. Ninety years later, real estate agents warned Henry Doelger against building housing in what they called the Fog Gap. He built it anyway, and most of this city is what he built. Here's where we lead.

09 / Client Voices
Everyone here says the same thing: it's foggy, so what. D&B were the first to tell us the fog once put the farmers out of business on this exact hillside. After that the conversation about our building went differently.
Our building is 1953 and looked fine. It was not fine. What they pulled out of the wall junction was seventy years of never quite drying out, and none of it was visible from the walkway.
They told us not to book the sealing for February and gave us a date that would actually cure. I've had three contractors here who didn't think that mattered. It matters.
10 / Local Context
Everyone knows Daly City is foggy. Almost nobody knows the two facts that make that worth acting on. The first is agricultural. After an 1853 government survey opened this land to settlement, mainly Irish farmers took up ranches across what is now Westlake and Serramonte. Within about a decade several families had abandoned them, because the fog density here killed their grain and potato crops. The families who remained gave up arable farming and switched to dairy and cattle – a fog that ends a wheat crop does not bother grass. The second is commercial. In 1945 Henry Doelger bought 1,350 acres of pig farms and cabbage patches on the bluffs above the Pacific, and the real estate agents of the day advised him against it, on the grounds that he would be building housing in what the trade called the Fog Gap. He ignored them and built Westlake between 1948 and 1962 – one of the largest private housing developments in California in the 1950s. Put those together and the situation is plain. This city sits in the place the fog comes through, densely enough that within living memory it decided what could and could not be grown here, and then it was comprehensively built on. A wood assembly needs to dry to survive, the Peninsula's warm-summer climate never gets hot enough to help it, and Daly City removes what little help the rest of the Peninsula gets. Grass does not mind the fog. Wood does, every day, for as long as it stands.
Daly City was founded by refugees. On 18 April 1906 the earthquake struck just off the coast near Mussel Rock, and San Franciscans who lost their homes to the quake and the fire came south to camp on the ranches – among them the 250 acres John Daly had built up from a dairy job he took in 1853. Daly and the other farmers gave them milk. Then Daly subdivided, the refugees stayed, the tracts followed, and in 1911 the place incorporated as a city by a margin of 132 votes to 130. It stayed small until Doelger arrived. Westlake is what most of this city physically is: monostylistic architecture designed by one core team to cover nearly every building in the development, on lots of about 3,300 square feet where the rest of the Peninsula runs 5,000 or more, built so efficiently that Doelger was called the Henry Ford of housing. About 40% of Daly City's housing stock was built before 1950. That is the number to sit with. Four in ten buildings here are older than the fog-gap subdivision that made the city famous, and all of them have spent every year since in the same air. The pre-war and Westlake-era stock is Renovation & Remodel work rather than replacement, and the rental inventory across all of it is SB 721 Inspection territory on the six-year cycle.

In Daly City we most often address: (1) decay with a completely clean surface, which is the signature condition of a place that never dries – staining and softening are products of wetting and drying cycles, and an assembly that is simply damp most of the time produces neither while the framing goes; (2) wall junctions rather than walking surfaces, because in this air the moisture is ambient rather than falling, so it arrives at the connection from every direction and a recoat of the deck addresses none of it; (3) sealant and coatings that were applied in the wrong month and never cured properly – a real and avoidable problem here, and about half the failed repairs we are asked to look at failed on the calendar rather than the specification; (4) guards on pre-1950 stock whose fixings predate every current requirement and have spent seventy-five years in this – Railing Repair & Replacement at the fixing, not the picket. Because nothing in this climate will ever force the issue, Annual Maintenance Plans are the only mechanism that puts anyone under the building on a schedule.

12 / Common Questions
$400-$800 per building for a 3-8 unit property. Age drives the number here less than most owners expect and exposure drives it more. With about 40% of this city's stock built before 1950 and all of it standing in the same air, the useful question at the walk is how the assembly has been detailed and where the moisture reaches, not what the permit says. The site visit is free.
Because the fog here has a track record, and it is not atmospheric colour - it is documented economic history. Irish settlers farmed this land from the 1850s; within a decade several families walked away because the fog density killed their grain and potato crops, and the ones who stayed switched to dairy and cattle because pasture tolerates what wheat does not. Ninety years later, real estate agents told Henry Doelger not to build housing here, in what the trade called the Fog Gap. He built 1,350 acres anyway. So this is not a foggy city in the way people mean when they say a city is foggy. It is the place fog was dense enough to decide what could be grown, and then somebody put a city in it. Wood decay needs sustained moisture and moderate temperature and is stopped by heat and drying. A Peninsula warm-summer climate already withholds the heat. Daly City withholds the drying on top of it. Every year, for as long as the building has been there.
It is close to no news at all, and the reason is worth a minute. The visual signs owners are trained to look for - discolouration, a spongy tread, a dark patch under a threshold - are produced by cycles: something gets wet, dries, and leaves a mark. An assembly that is simply damp, more or less continuously, does not cycle and therefore does not mark. The moisture goes in, stays, and works on the framing behind a membrane that looks the same as it did a decade ago. So in this city a clean surface is exactly what a fifty-year decay problem looks like from the outside, which is precisely the situation SB 721 was written for: it requires elements to be inspected, not looked at, and on this stock that distinction is the entire difference.
Inspect, yes. Seal and coat, no - and we would rather say so than take the booking. Sealant needs conditions to cure and an opened assembly needs to dry before it is closed, and neither happens reliably in a Daly City February. About half of the failed repairs we are called out to look at in this city failed on the calendar rather than the specification: right product, right detail, wrong month. So we will tell you if the date you want is a bad idea for your scope and give you one that works. Inspection is different - it can happen year-round, and honestly the damp season is when a moisture problem is easiest to find, because that is when it is at its worst.
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. Daly City leans to the second - this is largely older rental stock in a city built as subdivisions rather than associations, though Westlake's own homeowners association has enforced limits on exterior changes for decades and there is condominium inventory around Serramonte and Skyline. A detached single-family association with no elevated elements sits 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. Daly City is 105 miles from our North Highlands yard and we are straight that we are not the crew for something in the next hour. We schedule northern San Mateo in blocks and bring the full crew and materials in one mobilisation. Genuine safety issues we move on immediately regardless - though the honest note about this city is that the finding that matters is almost never the one that got reported, because the thing that has been going wrong for fifty years never gave anybody a reason to call.
