Zwaag Termite Control Simi Valley Reviews: Elite Repairs (2026)

Last Updated: 2026 | Data verified by The PCC Research Team

Killing termites is only half the battle. If you have an active infestation, you also have active structural damage. You need a company that excels at carpentry just as much as they excel at extermination.

In our Simi Valley pest control guide, we constantly warn homeowners about “spray-only” companies that kill the bugs but leave your eaves, decks, and support joists rotting and dangerously compromised.

To find the best pest control companies in Simi Valley, we audited raw, verified Google Maps reviews from local homeowners and real estate agents. Our 2026 data extraction revealed that Zwaag Termite Control is arguably the best structural repair team in Ventura County. Their carpenters perform surgical wood replacements that render decades-old damage invisible. However, to maintain absolute transparency, we also uncovered a notable vulnerability in their business model: their reliance on subcontractors for the actual fumigation tenting. Here is the verifiable truth.

Service Deep Dive: Surgical Wood Replacement

As detailed in our termite biology guides, Drywood Termites actively hollow out the structural framing of your home. Zwaag Termite Control stands out because their repair crews operate more like high-end carpenters than traditional exterminators.

Our data shows that their teams take on highly complex repairs—such as replacing hard-to-reach deck joists and sunroom siding—and they meticulously paint the new lumber to seamlessly match the home’s exterior.

• “Noting that our deck is 30+ years old it was suffering in a few areas from the original termite damage and dry rot. The Zwaag team showed up on time and did a meticulous job of replacing some of the support joists. These are very difficult to get to but Rudy and Ricky surgically removed the damaged areas and replaced them with new lumber and even painted the lumber with paint I supplied. You literally cannot tell where they have been!” — Dan Halpert

• “Bill Pederson was the excellent home inspector who performed a very thorough check for signs of termite damage or other damage to wood… The Zwaag crew that did the work for us are some of the most conscientious, professional & kind men I have met… Nick, José & Davíd were great!! José noticed a big problem with the wood on part of the outside of our old sun room. I had given up on getting the deteriorating wood removed & replaced. Oh, my goodness! José & his partner did an amazing job!” — Pam Abernathy

Service Deep Dive: The Go-To for Real Estate Escrows

During a home sale, a bad termite inspection can destroy a deal. In our industry comparisons, we weigh the opinions of Realtors heavily, as they see dozens of termite reports every year.

The data reveals that Zwaag Termite Control is highly coveted by real estate professionals in Simi Valley. Their inspectors are trusted to provide honest assessments without manufacturing “phantom” damage to inflate repair bills.

• “I highly recommend Bill Peterson and Zwaag Termite Control. During my many years of real estate experience I was exposed to many termite companies. It is difficult to determine the honest from the dishonest ones as you are at their mercy regarding their findings. I have seen two companies give conflicting reports for the same house within a week of each other… I recently had to track down Bill Peterson who has established himself over many years as an honest and reliable person to do business with.” — Walt Kainz

The Limitations: Subcontracted Tenting & Scope Disagreements

To guarantee absolute transparency, our data audit seeks out and isolates negative experiences. While Zwaag’s in-house repair team is legendary, we uncovered a highly specific operational flaw regarding their fumigation process.

Zwaag utilizes third-party subcontractors to execute the actual chemical tenting. One reviewer reported that when the subcontractor performed a “shoddy” job, Zwaag’s management was unwilling to take accountability for the sub’s actions. Additionally, we flagged a 3-star review regarding a dispute over extensive dry-rot discoveries expanding the scope of the repair bill during a home sale.

• “Hired Zwaag to do wood repair and tenting my home. I’d give the wood repair 4 stars as they did a good job… It went down hill from there as Zwaag sub contracted out the termite treatment. Whoever they used, did a shoddy job. I’d give them 1 star. The most disappointing part of the entire job was when I called to complain about the termite company, Zwaag just passed the buck to the termite contractors. I did not contract with the termite company nor pay them. I contracted with Zwaag. You’d think they would care about the entire job but they did not.” — John Plummer (2-Star Rating)

• “Used them for my home sale, very expensive repairs, with loads of extras found, by then they have you over a barrel. Failed to replace gutters they removed so we had to do that ourselves.” — Joanna Dyer (3-Star Rating)
