Reviews Speak Volumes

It’s been a gratifying experience reading through reviews, the vast majority praise this Cascade model to distinction levels, wonderful feedback confirms this.

I bypass individuals who downgrade a shed to 1 start simply because it doesn’t fit their lawnmower. Please check internal dimensions below whether it will serve your storage requirements. One guy struggled lining the doors up correctly and another had problems with the roof but this maybe down to the foundation requirements.

Whenever constructing a resin style shed, the priority to accomplish delivering an easy assembly resulting with a well grounded shed is to ensure the foundations are solid and level. The correct procedure requires preparing a level wood or concrete base.

Initially we were oblivious to this foundation rule due to sales sites failing to mention however we thought we’d better comply as this stipulation headlined the instructions. It’s worth taking note to administer a straightforward construction.

Level footings serve to aid assembly due to the panels aligning plumb whilst a solid base ensures the built-in floor performs to the description, able to cope with heavy duty demanding storage pressure. The importance of this rule becomes apparent upon constructing.

Top tips from a few is to assemble the facade centre panel at the back first followed by the sides. The panels slide into one another however assembling in this order makes the opposite corners snap into place so much easier.

Inserting the center screw into the door windows first makes aligning the windows a snip. Unfortunately these alignment directions are mentioned too late on in the instructions whereas they should be mentioned at the beginning.

Apart from the odd niggle, the instructions seem very straightforward yet there are a lot of screws, unfortunately these are essential to provide a sturdy structure. Some have constructed in 3-4 hours whereas others have taken half a day – Who cares, take your time and make a good job.

Overall, fabulous feedback received resulting in a sturdy, low maintenance and weather resistant storage solution boasting a modern attractive design.

The Cascade’s Roof

For me, Suncast probably incorporate the best roof design regarding the markets competition of resin sheds. It’s well angled and very steep ensuring effective rainwater drainage, delivering an immediate rainfall escape route.

The roof is manufactured from resin, blow molded into a thick resin based topping displaying an attractive tile effect described as shingle style. Supplied in sheet form, they interlock and secure with screws around the steel infrastructure and the walls.

The roof protrudes adequately beyond the shed walls creating eaves, an advantage preventing rainfall puddling and entering into the shed where the roof adjoins the walls.

Cascade roofs represent no future re-roofing unlike disintegrating roofing felt succumbs to. Resin provides defence against weather attack, it’s waterproof, durable and resistant to decay whilst a pressure hose is the only duty required to maintain the attractive appearance.

Heavy-Duty Built-In Floor

The floor is built-in to the shed providing a clean environment further increasing storage protection. The advantage regarding this built-in feature is the prevention of debris blowing inside the shed at the base of the walls and pests entering looking for shelter.

Moulded resin sheets make up the floor’s footprint designed into a thick hefty base, adjoining to the walls providing an enclosed unit. We’re impressed with how clean the internal environment results with regards to this feature.

Purposely toughened to survive heavy duty pressures, storage of heavy items is no problem for Suncast sheds. Although you won’t be driving into a shed this size on a sit-on-mower, the floor can cope. Hopefully providing the information how tough this floor is.

These hard-wearing credentials however will only suffice if the shed sits on a solid level surface such as wood, paving slabs or a concrete base.

Embedded within the floor are anchor points for the advisory measure of securing the shed down into the foundations. Anchor screws are not supplied as the type required is dependant on the foundation material.

Suncast – Low Maintenance Credentials

Low maintenance is Suncast’s delivery, accomplishing with remarkable style.

A quick wash down when mucky is the only upkeep duties Suncast sheds are blessed with. A light hose down is the prefered option for most to bring the shed back to the pristine condition, the day it was built.

Suncast recommend multi-purpose cleaners such as Simple Green, 409 and Fantastic, many opt for a couple of cups of white vinegar into a bucket of hot soapy water and wipe away any ingrained marks that’s hard to budge with a soft brush, works great for us. Refrain from using abrasive cleaners however as you don’t want to scratch this wonderful facade.

No more expense, no more re-staining, no more peeling paint and re-varnishing rotting wood and no more future time associated with the hassle re-roofing jobs entail either. All these problems have been replaced with an effortless wash.

Obeying by the priority resin sheds rule will accomplish a fast efficient assembly due to the panels aligning plumb, the doors line up and the hard-wearing floor will serve as it’s designed for, heavy duty purposes.

Top tip from all shed builders is to go through the instructions first and place all the parts in order to the assembly instructions. Believe me, the job goes so much smoother.

This shed requires two people to assemble and you will require room around the shed and a ladder for constructing the roof.

    Hi Simon,
    After much research for a storage shed we finally decided on either a Suncast Cascade or Suncast Tremont for our courtyard. We were very disappointed to find that you do not ship to Australia. Is there anyway around this?
    Kind regards,
    Janine (Perth Australia)

    • Hi Janine, to be honest I only concentrate on pointing visitors towards UK and USA prices due to the amount of upkeep work there is in making sure the sales links are still valid. I have many people in Canada and Europe presently saying the same after reading reviews but this website is solely written and maintained by myself therefore time’s rather restricted.

      There maybe an alternative solution with regards to imports, many sellers on the eBay platform offer shipping overseas, many of them offer this service as free shipping but they do all vary.
      This Suncast Shed link goes to the eBay platform displaying a selection of Cascade and Tremont sheds to which you could ask the seller whether they ship to your home in Perth.

      Hope this helps, good luck!

    really like the look of your site its organized and easy to read provides pricing in both UK and USA. I currently have a big wood shed I wonder if plastic goes to 9×12 feet ? Anyway they are reasonably priced and would seem to last a lifetime and no painting thank you for providing this insight very interesting site thanks .

    • Simon

      Hi Martin,

      The largest plastic sheds I have reviewed so far are the Keter Factor 8 x 11ft:

      Then there’s the Keter Oakland 7.5 x 11ft Shed with it’s sublime silvery-grey facade. This is the first resin shed designed with paintable resin allowing you to add a splash of colour to your surroundings:

      Yes I agree with the low maintenance values this type deliver where upkeep time is of prime importance. A wash down is all these sheds require to bring them back looking new again. Reasonably priced too in comparable to the wooden variety.

      Thanks again for stopping by Martin,


  3. Emma

    Thanks for the great in-depth review of Suncasts plastic sheds.
    They definitely might be what I’m looking for to store things on my back patio.
    One question though, the review says they have weather proof tendencies but will they stand up to torrential rain and keep everything dry inside?

    • Simon

      Hi Emma,

      Thanks for dropping by and leaving a comment.

      This Suncast model is the right size for most patios and it’s surprising what this facility can hold if you opt for stand alone shelving as you will be able to store all your patio accessories and gardening equipment etc all the way up to the ceiling.

      It’s completely weatherproof, resin is impermeable and waterproof to the max with the added benefit of nothing rotting and decaying and not having to re-stain and re-roof in future years.

      This will keep the rain out no matter how much of a downpoor you get. This has the best steep roof in my view out of all the reviews so far so there’s no chance of water puddling up above as the angle forces rainfall to run off straight away.

      Hope this helps Emma and thanks again,
