DeCloet Greenhouse

Every greenhouse manufacturer starts with a vision to give plants the best growing environment. They strive to meet structural engineering standards, but practical constraints like material costs and market pressures often require thoughtful compromises to maintain affordability and competitiveness.

DeCloet Greenhouse is the exception here.

This company stood its ground, never detracting from the set path since 1986, earning a loyal base of customer that appreciate its commitment to quality and no-compromise mindset. Specializing in designing and manufacturing durable greenhouses, it offers a full range of models that blend indoor agriculture with permanent building structures. These stick-builds are stronger than most, enabling taller greenhouses that outperform budget options.

“The extra height in our structures brings a world of difference in plant growth and climate control in ways that more temporary or budget-focused solutions simply can't match,” says Patrick Gelineau, GM.

Even with their larger dimensions, DeCloet’s structures always comply with building codes, whether or not permits are required. The commitment to providing the best growth environment for plants defines its work.

When conceptualizing a greenhouse, DeCloet offers standard heights of up to 16 feet under the gutter for gutter-connected builds and custom projects reaching up to 26 feet. The extra height creates a different environment for plants, with reduced humidity, better ventilation and more consistency in the internal climate that’s far more conducive to their growth.

Once a customer decides to invest in these long-term benefits, DeCloet starts with a consultative client engagement. Instead of jumping to pricing, the team dives into each SOP, tailoring solutions to fit. From double poly roofs and Venlo glass systems to Grow Max models, cold frames, or Norfolks, each build is designed for optimal growth. The company also delivers installations, heating, ventilation, bench systems, wide-span buildings, and full after-sales support. Production growers, nurseries, and retail centers across North America use these solutions. It also produces wide-span buildings for headhouses and the mining sector.

To maintain service quality and retain hard-earned expertise, DeCloet overhauled its manufacturing to cut down on seasonality. Shifting from a reactive model to one powered by forecasting and quote tracking, team DeCloet now recognizes patterns to build inventory during slower periods while ensuring smooth project flow. Lean manufacturing has freed up resources that are invested back in the industry—something that didn’t happen before. The result is a more stable workflow, lower employee turnover, and a skilled team that keeps improving.

These capabilities came in handy for a customer in western Michigan. They needed a sizeable retail greenhouse with better ventilation than standard models. DeCloet Greenhouse developed the 42-foot triple-peak double poly gutter connect greenhouse in response. The first three acres were built in 2011, and steady expansions over the years brought the facility to nine acres by 2023.

“This was originally a custom solution, but it soon took off, quickly becoming one of our most popular offerings,” says Bekki VanLeeuwen, assistant general manager (AGM).

Apart from customer-specific solutions, recently, DeCloet launched the berry model to accommodate berries, while the clear sky A-frame trussed structure with an open interior, as seen in Europe, was also well received.

The company is able to provide the various greenhouse solutions based on the vast experience it has. Built on decades of know-how and driven by a commitment to innovation and doing things right, DeCloet Greenhouse is raising the bar for quality and durability in the greenhouse manufacturing world.
