Pest Inspections in Berkeley, CA
101 Exterminators performs licensed pest inspections in Berkeley and issues state-compliant Wood Destroying Organisms reports for escrow, refinancing, and owners who simply want to know. Berkeley's pre-1930 Craftsman, brown shingle, and Edwardian stock tends to produce a longer findings list than newer Alameda County housing, and buyers here read the report closely. SPCB Lic. #9119.
Home maintenance
How do you keep a Berkeley home ready for a clean termite report?
Keep the old wood painted, dry and reachable. Much of Berkeley’s housing went up between 1900 and 1930, and a California wood-destroying pest report records conditions likely to lead to infestation along with live termites and decay. On a brown shingle or Craftsman, steady upkeep of trim, drainage and access gives the inspector less to write up.

Keep rafter tails and trim painted
Drywood termites get in where paint has failed on rafter tails, window trim and porch framing. Scrape and repaint those spots before the August to October swarm season, keeping original woodwork intact.
Clean gutters before November
Berkeley gets about 25 inches of rain a year, nearly all from November to March. Clear gutters and check that downspouts drain away from the house before the first storm.
Keep shingles off the soil
On older houses, soil and planting beds build up over decades until siding or shingles touch the ground. Lower the grade or pull mulch back so there is clearance at the base of the wall.
Leave access open
An inspector reports on what they can reach and lists the rest as inaccessible. Keep stored items away from the attic hatch and any access panels in closets and the garage.
Fix leaks at sinks, tubs and toilets
Slow plumbing leaks soften subfloor wood and feed fungus. Check under fixtures twice a year and reseal tub edges and toilet bases when the caulk cracks.
When to do it
Painting in late spring and summer, gutters in October, and leak checks in spring and fall; start a season before you plan to list.

Common Questions
Pest Inspections FAQs for Berkeley
What does a Section 1 finding mean for a Berkeley home sale?
Section 1 means active infestation or existing damage, and it is the part of the report that most Berkeley transactions negotiate over — lenders frequently require it cleared before funding. It does not mean the sale is in trouble; on a pre-1930 house it is close to expected. The next step is scoping the corrective work, completing it, and issuing the Notice of Work Completed, which is the document your agent and escrow officer are actually waiting on.
Does a pre-1930 Berkeley house need the attic and crawl space opened for a WDO inspection?
Yes, if you want a complete report. California standards require the inspector to examine accessible areas, and anything blocked gets written up as inaccessible — which on an older Berkeley house is where drywood galleries and mudsill damage most often are. Before the appointment, clear the closet under the attic scuttle, unblock the crawl space hatch, and move storage away from the sub-area vents and the garage perimeter walls.
Who orders the WDO report in a Berkeley transaction, the buyer or the seller?
Either can, and in Berkeley's market sellers commonly order one before listing so findings are known and priced into the deal instead of surfacing during the contingency period. Buyers order their own when no recent report exists or when they want an independent read. The report belongs to whoever ordered it, so if you are a buyer relying on a seller's report, confirm the date and ask whether any of the Section 1 items have been cleared.
