If your seedlings have reached a few inches in height and the weather outside has stabilized to where you’re no longer seeing overnight temperatures below 40 degrees Fahrenheit, it may be time to start hardening them off to get them ready to be planted in the garden.

Generally speaking, building a swing set is cheaper than buying a prefabricated one, but this assumes you have all the tools and knowledge to complete the project. The average cost to build a swing set is $514, but you should also factor in the time and effort it will require—if you don’t want to give up your weekend, it’s worth considering buying instead of building.

You can start by finding playground installers in your area that have amassed mostly positive reviews online. Next, search for the companies on the Better Business Bureau’s (BBB) website to see if any consumer complaints have been filed. Once you rule out companies with poor reviews and a history of complaints, contact the remaining options and ask the following questions to find the right installer for you:

• Will you pull permits if required?

• Do you offer a warranty?

• How long do you expect the installation to take?

• Do you have experience working with the specific playground material I want?

It may be tempting to DIY the construction of a swing set to save money, but we don’t recommend it. Since children will use the swing set, the entire system must be solid and safe, meaning the cost savings aren’t worth potentially endangering them. Plus, most DIYers will have to build their swing sets out of wood, which won’t last as long as metal or vinyl and introduces the risk of splinters. Instead, hire a local playground equipment installer to ensure the swing set is built safely and efficiently, setting up your kids for fun for years to come.
