DIY Spray Foam vs Hiring a Contractor: Which is Best?
Your home is showing all the signs and symptoms that you need insulation and you want foam, but you need to decide if you want to try and install it yourself or hire an experienced contractor.
There are several things you should consider when thinking about updating your home’s insulation, the main one being how easy the project will be to do yourself and be ready to admit when it’s too much. There are some areas you won’t be able to do on your own, while others might be feasible to the handiest homeowner.
RetroFoam of Michigan has more than 15 years of experience insulating thousands of homes across the Michigan’s lower peninsula. We know everything there is to know about foam insulation and while we don’t use DIY spray foam kits, we can tell you where you can use them and where to call in the professionals.
In our continued efforts to educate homeowners, we have compiled the pros and cons of using DIY spray foam kits and hiring an insulation contractor.
DIY Spray Foam Insulation Pros and Cons
There are a lot of places where using a DIY spray foam kit makes sense and if done correctly can help you out.
Here’s a look at the pros and cons of using a DIY spray foam kit in your home.
- DIY spray foam kits are great for insulating small areas. The small areas around doors and windows are great small projects for DIY spray foam kits.
- Avoiding higher costs. The experienced homeowner could avoid a contractor’s minimum charge by doing these small spaces themselves.
- Kits are readily available. You can buy the kit at your local home improvement store and get the job done on your own time. You won’t have to wait on anyone, but you should still take the time to learn how the kit works.
- The product doesn’t mix properly. One problem with DIY spray foam kits isn’t about the application and happens before it even leaves the gun. If the canisters aren’t hooked up properly, then the mixture could be ruined inside the tanks. You can see problems as well if there is a backup in the hose or the gun. When this happens, it ruins the remaining material in the tanks, which will cost you more money.
- The nozzle clogs pretty quick. You need to know what you’re doing when using a DIY spray foam kit, because a pause longer than 30 seconds will clog the nozzle. You will need to swap out the nozzle in under 30 seconds, lest the clog spread into the hose and tanks ruining the rest of the product.
- Foam can be very sticky. When using a DIY spray foam kit you will need to ensure you are spraying the material where you want it to be. Foam, when mixed correctly, will stick to everything and isn’t easy to remove. Keep in mind you will need to wear a hooded suit, gloves, a face mask, and eye protection.
- The foam won’t stick. On the other side of being sticky, if the material isn’t mixed properly it won’t stick to anything. When this happens, it falls away from the surface it was sprayed on. This can also happen if the surface where the foam is to be applied isn’t prepared or is wet.
- Overspray of the material. If you’ve never used a DIY spray foam kit before it’s impossible to know how the foam will react. It’s also hard to predict how the foam will expand once it touches a surface and starts curing. If you think you haven’t applied enough material and then spray more, you could end up with too much. This leads to wasted product and wasted money.
- Only open cavities in existing homes can be insulated. If your walls need insulation, a DIY spray foam kit won’t work. The only way to insulate existing enclosed walls is to call an insulation contractor.
Hiring an Insulation Contractor Pros and Cons
At times hiring a contractor can cost more than just doing the work yourself, but you need to own up to the times when calling a professional will save you time and money on your insulation project.
- Insulating existing walls. Areas of your home like existing enclosed walls can be insulated by a professional without tearing down your drywall. Contractors can do jobs of all sizes, whereas it is very difficult to do large spray foam jobs as a DIY project.
- Less time and stress to insulate the home. The amount of time to insulate your home will be drastically cut down when hiring a contractor compared to trying to do it yourself.
- Contractors are licensed and insured. A good contractor will carry a license and insurance. They do this so that if anything were to happen, then they can take care of it.
- Disposal of old insulation. An experienced contractor will remove and dispose of any existing insulation in areas like the attic, crawl space, and rim joist.
- Knowledge of building codes. A good insulation contractor will have an understanding of the current building codes, energy efficiency codes, and rebates. They will also know what to look for as far as structural issues, mold, mildew, and animal infestation signs.
- Contractors are more expensive. Hiring a contractor can be more expensive than a DIY project that goes off without a hitch and doesn’t misuse any products.
- Hiring the wrong contractor. Do your due diligence to make sure you hire a contractor you can trust and is experienced. You don’t want to find out the hard way.
- Waiting for installation. You may have to wait several weeks in some cases to get on the contractor’s installation schedule.
The Best Decision for Installing Foam Insulation
Unless your job is really small, it may make sense to hire an insulation contractor for your project.
To effectively improve your home’s comfort and energy efficiency over the long-term, an insulation contractor who is qualified and licensed is preferred, according to Icynene.
While some homeowners have a plethora of experience and are quite handy, that may not be you and there’s no shame in that. To save yourself the time, stress, and energy, as well as money if things go wrong, hiring an insulation contractor is your best bet.
