Provider snapshot
What this listing says
Seattle-area homeowners who want mold remediation from a large, established home services company with HVAC and plumbing under one roof, especially when mold traces back to a heating or plumbing issue.
Best for
- Seattle, King County, or Snohomish County homeowners who discover mold tied to a plumbing leak or HVAC condensation issue and want one company to handle both the source fix and the mold work.
- Homeowners already in Greenwood's membership club who want to keep their restoration work with the same company that services their heating and plumbing systems.
- Situations where mold remediation needs to be coordinated with duct cleaning, since Greenwood handles both in-house.
- Buyers who value a company with a century-long local track record and large support team, even if mold isn't the company's specialty.
About this company
Greenwood Heating and Home Services is a large, locally owned home services company headquartered in Tukwila, Washington, serving the greater Seattle metro area. They've been around since 1921 — over 100 years — and their core business is heating, air conditioning, electrical, and plumbing. Mold remediation is one service line under their "Restoration" division, alongside storm damage and fire/smoke damage restoration.
Their mold page lists inspection and testing, containment, mold removal with HEPA filtration, and restoration and prevention. They highlight familiarity with Puget Sound moisture challenges. But the website is light on mold-specific detail — no named equipment beyond HEPA, no described testing methodology, no case studies. Mold is clearly a secondary offering for a company built around HVAC and plumbing.
Greenwood has two offices — the main location on Interurban Ave S in Tukwila and a second in Everett — and they run a membership club, financing options, and 24/7 support. The company employs a large field team across multiple trades. They run their own training program called "Greenwood University."
A 4.9-star rating across 4,420 Google reviews is genuinely rare for a company this size. Most home services companies with thousands of reviews settle in the 4.5-4.7 range. That said, the reviews overwhelmingly reflect HVAC, plumbing, and electrical work — not mold remediation specifically.

Review consensus
Reviewers consistently name individual technicians who communicate clearly, arrive on time, and explain their work step by step. Shay Berg gets repeated praise for thorough diagnostics and friendly service. Mitch is highlighted for sewer and drain work. Dustin DeLaRosa, Alek, Corey, Theresa, Daniel Medel, Joshua, Lucas, Michael Geychenko, Drew McDonald, and Thuan Tran all receive individual 5-star mentions. Several reviewers specifically praise the dispatch system that sends tech photos and arrival windows. The company draws loyalty from longtime customers who use them across multiple trades.
18 found across 4420 total reviews at 4.9★. Pricing dominates the complaints. Shalimar Gonzales was quoted $26K for a tankless water heater replacement that other companies bid around $10K. Jason Naranjo, a 13-year customer, got a $33K bid for a heat pump system upgrade — half the price elsewhere. Eli Meckler received a $20K estimate for a water heater job completed by another company for $10K. Charyn Mann paid $850 for a faucet replacement that took 80 minutes. Valna Wilson called estimates "ridiculously expensive." Beyond pricing, follow-up failures appear repeatedly. Alison Caditz paid $80 for a plumber who promised to follow up and never did, despite multiple calls to customer service. Matt Combs was told he'd get a call the same day — it never came. Achille Mileto's wife took the day off for a plumber who never showed and never called. Aaron George describes a technician who declared a furnace unrepairable and scheduled a sales visit, but a second-opinion technician found nothing wrong. Jeremy Weir says project manager Matt showed no interest in finding installation solutions.
Greenwood's owner responses follow a template pattern. Nearly every response thanks the reviewer, expresses concern, and either asks for more information or says the feedback will be shared with the team. Few responses engage with the specific complaint. Multiple responses include "we are unable to locate you in our system" — at least two reviewers (Johnny Boi, DJ Unknown) received this response, which may reflect fake reviews or simply name mismatches. The pricing complaints are structurally consistent: a large company with two offices, a truck fleet, a training university, and marketing overhead has higher costs than smaller competitors. Several reviewers explicitly connect the pricing to the company's scale.

Greenwood's field technicians consistently earn praise for clear communication and solid work. The problem is pricing — get competing bids before signing anything. If you use them for mold work, ask specifically about their mold remediation experience and crew, since this is a secondary service line for a company that primarily does HVAC and plumbing. Request Shay or Mitch if your mold issue connects to a plumbing or HVAC problem.
Keep in mind
- Greenwood does both mold testing and mold remediation. That's a conflict of interest — the company deciding you have a mold problem is the same one billing you to fix it. Get an independent test first or ask them to use a third-party lab for testing.
- Pricing is by far the most common complaint across Greenwood's negative reviews. Multiple reviewers report being quoted two to three times the price competitors charged for the same work. Get at least two other bids.
- Mold remediation is a small part of Greenwood's business. Their 4,420 reviews are almost entirely about HVAC, plumbing, and electrical. You won't find a track record of mold-specific feedback to evaluate.
- Several reviewers describe a pattern where a technician diagnoses something as unfixable and immediately schedules a sales visit to push full system replacement. Ask whether a repair is an option before agreeing to replacement.
