Homeowners have plenty of options when they need a plumber, electrician, or HVAC technician, which makes a long track record of customer feedback worth noticing. Mainstream Home Services has served the Inland Northwest since 2000, growing from its beginnings in electrical work into a company providing heating, cooling, plumbing, drain and sewer, electrical, and indoor air quality services. Today, Mainstream’s website reports more than 5,700 verified Google reviews and an overall rating of 4.8 stars. Those reviews accompany a business that has spent more than 25 years building its presence around Spokane and North Idaho. Mainstream now operates from Spokane Valley and serves communities on both sides of the Washington-Idaho state line.
Thousands of Customers Have Responded
A handful of positive reviews can offer some insight into a home service company, but thousands create a much larger record for prospective customers to examine. Mainstream’s review page reports that its reviews are pulled directly from its Google Business Profile rather than edited or curated for display. At the time of writing, the company reports 5,734 verified reviews and a 4.8-star overall Google rating.
That volume matters because home service covers many different situations. One customer may call about a furnace that will not start, while another needs an electrical repair or a new water heater. Mainstream’s customer feedback therefore reflects experiences across several trades rather than one narrow type of work.
“We recently had Mainstream come and assess our HVAC system..very thorough with his inspection, pointed out things he was seeing, then went over his findings with us…We were very impressed with Mainstream, their communication regarding appointments was excellent…The installation was able to be set up within a few days, and we have no doubt it will be a smooth process.” – Jennifer A.
The company has also established service policies intended to give homeowners clearer expectations. Mainstream says it uses flat-rate pricing approved before work begins. Its technicians are Mainstream employees rather than subcontractors, and the company says they are licensed, background-checked, drug-tested, and continually trained. Mainstream also backs its work with six written Home Comfort Guarantees.
Plumbing Is a Local Need
Mainstream’s Spokane operation deals with the realities of the area’s housing stock. The company notes that Spokane includes everything from century-old Craftsman homes to mid-century houses and newer subdivisions. In some pre-1960s neighborhoods, original cast-iron and galvanized lines remain common. Mainstream identifies plumbing as its most frequently requested service in Spokane.
That makes professional drain cleaning in Spokane more than an occasional convenience. Slow drains, recurring clogs, sewer backups, and aging lines can require equipment and diagnostic work that go beyond a bottle of drain cleaner. Mainstream offers drain cleaning, hydro-jetting, sewer line repair, and camera inspections alongside its regular plumbing services.
The company also handles leaks, repiping, fixtures, and water heaters. Because drain and sewer trouble can have several possible causes, access to camera inspection and other diagnostic services can help technicians identify the location and nature of a problem before recommending the next step.
“We had to have the basement floor drain cleaned and were very impressed…we only use Mainstream for our plumbing needs. No fuss, no hassle and no hard upsales. Thank you again.” – DiMarie F.
Helping Homeowners Plan Ahead
Many service calls happen after something stops working, but homeownership gets easier when maintenance starts before a breakdown. Some of the most useful home improvement tips are surprisingly unexciting. Keep up with routine HVAC maintenance, pay attention to drains that repeatedly slow down, know the age of the water heater, and do not ignore electrical behavior that suddenly changes. Catching a developing problem can give a homeowner more time to understand the options.
Mainstream’s service model includes preventive work as well as repairs and installations. The company maintains furnaces, heat pumps, boilers, and air-conditioning systems and offers a Care Club maintenance program for homeowners who prefer to have equipment inspected on a schedule.
This approach makes sense in Spokane’s climate. Mainstream notes that local homes experience hot, dry summers that can climb above 90 degrees and winters that can fall into single-digit temperatures. Heating and cooling equipment gets a real workout across those seasonal extremes. Regular inspections cannot guarantee that a component will never fail, but they can uncover wear, performance problems, and maintenance needs before homeowners find themselves dealing with a surprise breakdown.
“My brother and I have used Mainstream for years. They’re always solid. Quick, top tier customer service and highly competent tradesmen. Things they fix or install stay working…the job is done right the first go.” – Devin D.
Reviews Reflect Daily Service
Online ratings are most useful when people look beyond the number at the top of the page. Mainstream’s current reviews include customer comments about plumbing, electrical work, water heater replacement, and other services. That variety gives prospective customers a chance to read about jobs resembling the one they may need.
Mainstream has built several practices around the parts of home service that can make customers uneasy. Its flat-rate pricing means customers receive and approve a price before work begins rather than watching an hourly bill increase during the visit. The company also says technicians use shoe covers and drop cloths and clean the work area when the job is finished.
“Very thorough and took the time to explain everything. The work area was spotless when he left and everything is working well. Highly recommend!” – Mary P.
Mainstream’s written guarantees add another layer of accountability. Its six guarantees address pricing, technicians, satisfaction, installations, leaks, and drain or sewer backups. The company describes these commitments in writing rather than leaving customers to rely on a general promise that it stands behind its work.
With more than 5,700 Google reviews, maintaining a 4.8-star average suggests that a large number of customers have taken the additional step of publicly recording their experiences. No review score can tell an individual homeowner exactly how a future service call will go, but a large body of recent feedback provides useful information when comparing local companies.
A Reputation 25 Years Strong
Mainstream’s current review count looks even more notable when viewed against the company’s history. What began in 2000 as a home-based electrical business eventually expanded into HVAC and plumbing as customers asked Mainstream to help with more of their household service needs. The company added heating and cooling in 2016 and plumbing in 2017, helping transform the original electrical operation into the multi-trade home service business it is today.
Growth also brought outside recognition. Mainstream appeared on the Inc. 5000 three times, in 2018, 2019, and 2021. Its local footprint grew substantially as well, eventually requiring a move into a much larger Spokane Valley facility with additional room for employees, training, vehicles, and equipment.
More than 25 years after its start, Mainstream Home Services has accumulated something that cannot be created overnight: a substantial public record of customer experiences. More than 5,700 Google reviews and a 4.8-star average give Spokane-area homeowners plenty to read before making their own decision. For Mainstream, those numbers represent thousands of individual service calls behind a local name that has been part of the Inland Northwest since 2000.
