Suncast Cascade’s do stand among them

Cascade ‘s small range of quality plastic sheds consist of two models, both sizes have identical 7 ft widths across the frontage, only their depths vary. Cascade’s smaller model incorporates a 4 ft depth providing ideal dimensions for a patio location whilst their more substantial shed comprises a 7 ft length, accomplishing generous proportions to store an abundance of gardening equipment.

We became disillusioned with wood’s inability to survive the winters and swayed towards a resin composition to escape yearly maintenance issues regarding replacing rotting wood, the arduous task associated with re-varnishing and the burdensome assignments relating to re-roofing projects.

Low- maintenance initially captivated our interest due to resin’s facile cleaning ability, a swift hose down refreshes assembly day’s condition in minutes. We did consider metal for their security advantages however due to their thin skin being subject to unsightly dents plus seldom occupying integrated floors, an enclosed plastic construction was our preferred choice and delighted with the outcome.

Cascade’s Composition

Cascade’s make-up regards polypropylene resin, entailing a manufacturing procedure termed blow molded technology where the resin sheets are composed into a multi-layered skin.

It’s a shame the majority of sales-sites fail to mention plastic sheds foundation stipulations, most people find this essential requirement upon reading the instructions leading many to side-step this ruling however a decision not to adhere will probably lead to frustrations, poor feedback coinciding with a substandard construction.

It’s imperative foundations are solid and level, wood or concrete laid perfectly level elevated slightly above ground level to escape flooding provide ideal foundations. This one-step preparation process delivers a flawless construction eliminating assembly problems for the following reasons:

  • A level base provides the optimal platform to accomplish aligning the panels up with ease, 8 ft up on the roof can magnify problems aligning the roof sheets if you’re not perfectly level on the ground.
  • A vertical stance assures the roof weight applies equal force on all sides of the shed eliminating leaning pressures.
  • Level foundations ensure a vertical plumb alignment for the doors delivering the perfect swing and closure.
  • Solid foundations are imperative for the floor to cope with strenuous tensions applied by weighty storage.

Once the shed is erected, to increase stability and wind resistance levels it’s recommended to secure the shed floor down into the foundations through the anchor placements embedded within the resin floor. Anchor screws are not included as their type depends on the foundation material, wood or concrete.

    Hi Simon,
    Thanks for your reference. I reaaaaally learned a lot from your blog.Because I am changing a job and I’m gonna move to US soon. After I read your blogs I decided to get a nice plastic shed for my new backyard. I have some different choices from amazon but I don’t know which one should I get.

    Would you pls recommend me a nice shed if we can get in touch 🙂

    Your advice will be deeply appriciated and I defenitely value your insights.

    Thanks again Simon,


    • Thanks for reading, Celia – it’s difficult to recommend a resin shed, as they all offer different advantages along with providing weather-resistance.
      Hope you find the size of resin shed that serves your garden needs, and good luck with your move.

    Hello, Simon
    WOW! The Cascade shed is a nice looking shed. I can only imagine how it would complement any outdoor space. It would be great to move my garden equipment out of the garage and free up some space.
    When I look for any product that used outside, I look for a maintenance free. This shed seems to fill the bill for not only being maintenance free but a spacious building.
    I have looked at plastic buildings in the past and was wary of their durability. The Cascade shed has all the attributes that I would want in an outside shed. These buildings have come a long way from the buildings of the past.
    Thanks for enlightening me about how far these buildings have come. Seeing the plastic buildings of the past sagging or the doors and windows not working right has always steered me to a wooden or metal shed.
    Thanks again for updating me on Cascade Sheds.

      Hi Kevin,

      Thanks for taking a read about the picture perfect Cascade range of plastic sheds and whether they are the answer to what is the best plastic shed.

      We too were initially put off by the thought of plastic in comparison to wood but when we considered how the composition changed regarding wheelie trash bins, from the rusting metal style into a resin construction with similar strengths and increased durability, we started to seriously consider the quality plastic variety.

      After construction and adhering to the foundation rules, I think the reason a few people struggle aligning everything at ease, the floor to survive demanding pressures and the doors to work with the correct swing etc is probably down to side stepping the preparation of the correct foundations for the shed to sit on.

      Unfortunately most sales sites fail to mention the foundation stipulations yet they do headline all the instructions, so it is worth taking note.

      Thanks again Kevin,
