Can you install my shed?
Yes, installation is included with purchase.

Do I need to call to schedule my shed install?

A Gorilla Shed representative will contact you within 3-5 business days of your purchase date to review your order and schedule installation. The representative will also confirm your shingle color, optional paint color and any accessories at this time.

What is the standard lead time for installation?

3-6 weeks from purchase.

Do I need to be home for my shed installation?

A person at least 18 years of age will need to be present at the time of installation. You do not need to be home once the installation process has begun, but you should be home at completion for a walk through and to sign the certificate of completion.

How long will installation take?

On-site installation for most sheds can be completed within one or two days. Your installer will arrive with the wood pre-cut and pre-primed, minimizing disruption to your day and your landscape. Larger and/or more complex sheds will require additional days, yet still provide minimal disruption. Timing also varies based on location, leveling, and carry time at the assembly site.

Do I need leveling blocks?

Leveling blocks are not included with the purchase. Leveling blocks are not required in all states/counties, but the member should check his/her local requirements. Your building will be built on 4x4 pressure-treated runners. We will use treated leveling materials and shingle shims to level up the floor prior to installing the shed. If your ground is out of level greater than 6 inches, leveling blocks will be needed.


Will I need to obtain a building permit prior to my shed installation?

You should check with your local Building Authority and Homeowners Association prior to installation to make sure your shed is compliant with all codes, easements and setbacks.


Is painting included with my purchase?

Painting is not included with purchase and is the homeowner’s responsibility. Gorilla sheds are built using pre-primed siding. Manufacturer requires the use of 100% acrylic latex paint. All exterior horizontal and vertical joints must be painted. Doors should be painted on all 6 sides including front, back, and all four edges. Painting your shed to match your home often meets HOA requirements.

Is caulking included with my purchase?

As a Costco Member Exclusive, Gorilla Sheds will caulk all critical joints (addressed during installation). All additional caulking is at homeowner’s responsibility. Your shed is built like your home and should be caulked when painting. Manufacturer recommends paintable caulk. You should caulk all horizontal and vertical joints and any seams and gaps prior to painting.

How soon do I need to caulk and paint my shed?

Your shed should be caulked and painted within 30 days after installation. Check with your Homeowners Association to ensure compliance with architectural codes.

Is the shed sealed to prevent water from entering?

Our sheds are manufactured with the upmost precision to ensure every building meets our engineering standards. Once your shed is installed, be sure to caulk all remaining joints besides those critical joints already caulked by Gorilla Sheds as a Member Exclusive. Following these simple steps will prevent water from entering your shed.
