Estimation & Choosing a Spray Foam Contractor
Western Home Performance Sales will come to your home or business at no charge to provide an estimate and discuss our products.
- Spray foam is not for everyone, and we are happy to discuss alternative options, even if we do not offer them ourselves. It is important to us that we extend our experience and knowledge to all of our customers to ensure the best fit choice is made.
- It is very important to make sure whoever you hire to install spray foam are a licensed and experienced spray foam contractor.
You will want to make sure that the products they use are of good quality and have been tested and certified—not all spray foam products are the same.
- Be aware of the R-values, product characteristics, and material make-up.
- Spray foam products have come a long way since the old days, there is no need to worry about Formaldehyde.
- It is also a good idea to ask the estimator/sales person about any fire coatings that may be needed, if this is not included and is needed the inspector will likely not pass you—it could cost you more money than you planned.
- We have all the ICC Reports, MSDS, and Technical Data Sheets, available for you, for all our products.
We understand education is essential to making the right decision. We want to be upfront with the process of our spray foam installation, from start to finish. Spray foam is unlike any other sub trade, there is more set up time involved and our equipment is a bit more than a hammer and a tool belt. Below are a few details about the process:
- Should spray foam be the route you choose, and we hope it is, we will schedule your job for installation.
- At the time of scheduling, we will need to have a work agreement initialed and signed and will collect a deposit payment.
- Keep in mind, construction schedules can sometimes be delayed. We will be in communication with you immediately in the case of a delay as we value your time and your schedule.
- We operate out of a 20’ trailer which houses our generator, reactor, and a least two 50 gallon drums of material.
- We will need proper space to park the equipment so to access the installation area adequately. Our drivers are extremely skilled at maneuvering the equipment.
- The equipment is loud to run, you may want to warn your neighbors about the sound ahead of time. We will comply with city noise ordinances.
- To ensure the proper installation of the foam, we need to make sure we begin spraying at the right temperature. And depending on the weather, you can expect 45–60 minutes of warm up time.
- During warm up, we will begin masking and taping, if needed. Some customers choose do their own prep, either way is fine with us (this will be discussed at the time of estimation), but attention to detail is extremely important.
- Spray foam can be a messy process as the material is designed to adhere to the surface to which it is sprayed—so getting it on anything other items would not be good.
- There are instances of static, this is different than overspray, the foam flakes will most likely just brush off, the flakes are similar to the flakes from plastic peanut packing material.
- We take great precaution in avoiding any overspray and will take responsibility if our masking and taping is not sufficient.
- The guys will be fully masked and suited during installation. This is to prevent any inhalation of the material as it is applied, because as it is applied it expands at a rate of 120 to 1.
- Once expanded, the foam will begin to cure and harden in place. There are no off-gases once cured but depending on the ventilation of the area during the installation there could be a smell associated for a short time, nothing permanent. It will be similar to a couple of freshly painted rooms, if this is bothersome, you may want to leave the premises for up to a full day. The industry standard is, if the foam is being applied in an occupied space there should be a 24–48 hour evacuation while the product completely cures. This depends greatly on the application location.
- When it comes to the product and application, hiring an experienced and licensed professional is extremely important. The foam must be mixed and applied correctly which involves temperature control, thickness, and ventilation. You will see quickly, by asking questions, which contractor knows the most about the products they shoot. Always make your buying decision, when it comes to spray foam, based on more than just price but who is the most knowledgeable and experienced.
- Many customers will feel the difference in temperature and sound in their home or business as the foam is installed, it is that dramatic!
Open Wall Cavities
- In an open wall shoot (new walls) if it is a full fill, we will trim the wall cavities so they are flush in order to hang drywall. This will also be the case for any roof/ceiling applications where sheetrock will be hung.
- It is always a good idea to take a few pictures of your plumbing and electric before spray foam is installed, it will help to locate wiring and pipes should a problem arise. In the case of a problem, the foam can be carved out and patched with a kit.
- High performance building suggests to “insulate tight and ventilate right”—if you chose to seal your home, which is an excellent option to reduce energy consumption, keep in mind ventilation is essential, we cannot stress this enough.
- If your home is not ventilated correctly during and after installation of spray foam, there could be odors developing from other contamination sources, sources that have been in your home for many years which can start to become noticeable after you seal the home, as well as, a possible lingering odor from the foam itself. This is completely avoidable if you hire an experienced contractor using proper ventilation.
- A house is a system, you will need to consider what else could be affected with a change to this system. We can and will help you determine what, if any, affects you could encounter with sealing your home.
- We will properly ventilate during application on all jobs!
- We care greatly about the health and happiness of your home and family—we are committed to being a responsible spray foam contractor.
Existing Wall Cavities
- In the case of existing walls, we will fill the cavity from the bottom up using a delayed expanding wall pour foam, a foam that expands at a rate of 15 to 1—to prevent damage to the existing wall.
- In order to do a wall pour we will need to prep the walls, this includes drilling holes in each cavity vertically, one 3 inch hole at every 4 feet. We will either access the wall from the interior or exterior of the home. The option will be discussed at the time of estimation.
- Again, we can do the prep or you can do the prep, it is extremely important, if you choose to do your own prep that the site is ready when the sprayers arrive.
- We can also do the wall repair if needed, generally our customers do this, but if we do it we will repair it to paint ready.
- If we access the walls from the exterior of the home, most likely the panels of the siding will be removed and the holes will be drilled through the sub structure.
- If it is a case of an existing ceiling, we will need a much larger section of access as the wall pour foam product does not expand effectively horizontally.
For All Applications
- ALL applications are different and will entail a customized approach for installation.
- It is our job to know the codes and to let you know the best application method for your project. We have been shooting foam specifically since 2001—from homes, to refrigerator units, to digester tanks, boats, wine vats, props, chicken coops, we have seen and shot just about everything.
- After clean-up is completed we will do a walk thru with you to ensure your satisfaction.
- We will require your signature for approval, we will settle up payment, and be on our way.
If there are any questions or concerns, we are more than happy to address them. Our goal, again, is to create good experiences and happy customers!
