Structural Pest Inspections

Pest Inspections in Redwood City, CA

101 Exterminators issues state-compliant WDO reports for pest inspections in Redwood City — for buyers, sellers, agents and owners who want to know what is in the framing. SPCB Lic. #9119, licensed since 2005. A California report separates Section 1, active infestation or existing damage, from Section 2, conditions likely to lead to it. On a Redwood City house both sections usually have entries.

Local Context

What an Inspector Finds Under a Redwood City House Depends on Which Side of El Camino Real It Sits

Redwood City runs from restored salt marsh at Bair Island to the wooded foothills above Edgewood Park, and a WDO inspection reads differently along that line. East of El Camino Real — Friendly Acres, Redwood Village, the flats out toward Seaport Boulevard — the ground stays wet through the November-to-April rains and the findings skew subterranean: mud tubes on stem walls and pier blocks, damp sub-areas, wood-to-soil contact, fungus damage at the mudsill.

West and uphill it changes. The Craftsman and Victorian stock around Mount Carmel, Eagle Hill and Stambaugh-Heller drains well, and the findings there are drywood — frass pellets under kick-out holes, damaged rafter tails and fascia, galleries in window headers and attic framing. The middle of the city is post-war ranch and post-and-beam on slab with low-slope roofs, and those houses can generate findings of both kinds at once.

Escrow usually turns on Section 1. That is active infestation or existing damage, and it is what a lender or a buyer's agent asks to see cleared. Section 2 is the conditions list — earth-to-wood contact, a leaking shower pan, missing sub-area ventilation, cellulose debris under the floor — and on Peninsula transactions it often lands in the negotiation even when nobody requires it. Both belong in a report that is honest about what could not be reached.

How We Work in Redwood City

We inspect what California SPCB standards require us to access: attic, sub-area or crawl space, all accessible exterior wood, garage framing, decks, fencing and any outbuilding in the report scope. On Redwood City properties the sub-area is where the report usually gets decided, so we go under the floor on every house that has one. Every finding is photographed with its location, sorted into Section 1 and Section 2, and anything unreachable is stated as inaccessible rather than left blank.

Redwood City Climate

The "Climate Best By Government Test" arch downtown comes from a slogan contest a local resident won in 1925, and the survey behind it was real: a pre-World War I climatological comparison placed Redwood City alongside the Canary Islands and the North African coast. What matters for pest work is what that warmth does. The hills to the west block most of the marine layer that keeps Daly City and Pacifica cool, so summer afternoons here run hot, and the record high of 110°F was set as recently as September 6, 2022. Rainfall averages about 20.5 inches a year, nearly all of it between November and March. Drywood swarmers fly August through October, at the hottest end of the local calendar; subterranean swarms arrive with the rains, February through May.

Housing Stock

North and west of downtown, the Mount Carmel, Edgewood and Centennial blocks have pre-1940 houses on raised foundations, with the original redwood and fir framing still in the walls and attics and crawl spaces a technician can work in. Post-war tract housing spreads south and east from there. Farm Hills and Woodside Plaza went up mostly between the 1950s and the 1970s on the hillside side of town. Redwood Shores is the outlier: a 1960s planned community built on bay mud and former salt-evaporation ponds, with lagoons threaded through it and groundwater close to the slab. Termite species, foundation type and inspection access all change between those four.

Why Local Expertise Matters

Two Redwood City addresses can need opposite work. A 1926 house near Mount Carmel usually means drywood termites in old framing, reached through a crawl space and an attic. A Redwood Shores townhouse on filled ground usually means subterranean activity at the slab edge, plus moisture conditions that land as Section 2 findings on the report. Knowing which conversation you are in before the inspection starts is most of the job. We have been licensed and insured in California since 2005 and hold SPCB License #9119.

Warning Signs

Signs You Need Inspections Service in Redwood City

We inspect all accessible structural wood including attic framing, crawl space, exterior siding, decking, fencing, and garage framing. We check for both drywood and subterranean termites, carpenter ants, fungi and wood decay, and conducive conditions such as wood-soil contact, excessive moisture, and improper drainage. Our written report clearly identifies Section 1 conditions (requiring treatment) and Section 2 conditions (requiring further investigation or preventive repair) with photographs.

Common Questions

Pest Inspections FAQs for Redwood City

What does a Section 1 finding mean for a Redwood City home sale?

Section 1 means active infestation or existing damage — live termites, fungus damage, a rotted mudsill — and it is the part most lenders and buyers ask to have cleared before closing. Once the Section 1 work is done we issue the Notice of Work Completed, which is the document escrow actually wants. Section 2 items are conditions likely to lead to infestation and are usually negotiated rather than required.

Does a Redwood Shores condo need a pest inspection?

Often yes, though the scope is narrower than for a single-family house. In a condo or townhome the report covers the unit and the accessible framing serving it, while shared roofs, exterior walls and sub-areas typically fall to the association — so the HOA's own records matter as much as the unit inspection. On Redwood Shores properties near the lagoons we pay particular attention to moisture conditions and accessible framing near grade.

How long is a WDO report good for in a San Mateo County transaction?

California WDO reports are filed with the Structural Pest Control Board and are generally treated as current for two years, though lenders and buyers on Peninsula deals commonly want an inspection done in the last few months. Conditions change — a wet winter can turn a dry sub-area into a Section 1 finding. If you are relisting a Redwood City property after an escrow fell through, a fresh look is usually worth more than the old report.
