From a Small, Local Shop
to a Full-Service Team
LSM was founded in 1940 by John Wynstra and Pete Douma, originally to provide metal fabrication solutions for local farms and growing communities in Whatcom County.
In those early decades, innovation and practical craftsmanship were the standard. The company became known for building dependable heating solutions, including wood-burning furnaces and efficient oil furnaces that earned trust throughout the region.
Today, that same mindset shows up in everything we do, whether we’re repairing a furnace, installing a heat pump, replacing a water heater, wiring a generator, or fabricating custom metalwork.
A Legacy of Local Ownership
One of the things we’re most proud of is that LSM’s story has been carried forward through generations of local leadership—people who care deeply about the team, the trade, and the towns we serve.
Key milestones in our story:
1940: Founded in Lynden by John Wynstra and Pete Douma.
1977: Local family ownership continues as new leadership purchases the company.
1998: The company moves to 837 Evergreen St. in Lynden, where it remains today.
2008: Expansion into plumbing through the purchase of Alpha Plumbing.
2010–2011: Cory & Bobbi Kreider acquire their ownership stake as the next generation steps in.
2020: Electrical service is added, helping us cover your entire home with a single team.
As we’ve grown, we’ve worked hard to maintain our local roots: big enough to handle complex jobs, but small enough to treat customers like neighbors. Our team is committed to upholding a long-standing tradition of dependable, honest work. It’s all we’ve known for 85 years and counting, and it’s what you can expect from us on each and every project.

Frequently
Asked Questions
FAQ- During the summertime, your air conditioning is running a lot more than other months. Therefore, during this time you should change your filter at least once a month to keep it running properly. This includes pleated filters that claim to be 3 month filters. For other months of the year, use your best judgment.
- Every air conditioning system should be serviced, at least, twice a year. We recommend servicing it once in the springtime and once in the fall.

- SEER stands for Seasonal Energy Efficiency Ratio. The size of an air conditioner is rated in BTU or Tons, however, the efficiency is rated in SEER. This ratio is calculated as the cooling output divided by the power input for the average U.S. climate. It’s like MPG (miles per gallon) in a car – the higher the MPG (or SEER) the lower the gasoline (electricity) bill.
