Negative Sir. The chemical price has only gone up. It used to be dramatically cheaper 20-30 years ago. We just had another major price hike in December. Perhaps in your area as more and more contractors get in the business they are driving down the installed price to compete, but the raw...

Our company has been in business installing spray foam since 1977. Our owner worked for his father before that who started in the late 60's. We have never had a nightmare warranty claim thankfully, and have installed millions of sq ft of closed cell foam. It is far from a new unproven product...

Pics would help. Not sure I completely understand exactly what you've done. You said ceiling but it sounds like you mean roof. When you say ends of the building are you meaning gable wall end or soffit end? If you stop the warm air from hitting a cold condensing surface you would be fine, but 1...

Any vapor barrier should go towards the predominantly warm side. I get your meaning but cold cannot be reflected, cold is just the absence of heat. We generally will use a ramset tool, nails with washers, but you can also use adhesive or can foam which is a very powerful adhesive.

Its gonna be hard to come up with a solution thats easy, permanent, but also cheap. Be aware that the metal siding is a vapor barrier. I wouldn't use plastic inside mixed with batts. Also, air sealing the soffits with permeable insulation against the roof and no vents, then adding propane in...

Yes sir im trying to identify the air compressor pump, electric motor is known.

Thank you that is very helpful. I will measure bore and stroke and external dimensions to confirm. If it is a 230 and based on record of change 30 it would be from 1965. Amazing how long old equipment used to last compared to current day stuff.

A friend of mine offered me this old air compressor that is otherwise getting scrapped. I am 90% sure its a Quincy. Its been sitting in the elements and is obviously rusty but I can clean that up. Step one is identifying the thing so I can price parts to see if it is a worthy candidate for a...

That would be open cell. Closed cell is very difficult to shave. Wouldnt suggest open cell in a 2x4. Thats only R12 which is below code in majority of areas.

They wanted $15k for 1600 board feet? Something isn’t adding up. Even 1600 for 1600 uninstalled is way overpriced.

DIY spray foam kits are good when the area to be covered is less than most pro spray foam contractors minimum charge. In our area the cost of kits is more than the cost of professional installation by a significant amount. We do at least 2 jobs a year where someone starts and then gives up and...

Oh man. This is absolutely the responsibility of the installer and should never be put on the customer.

You can prime if you want. Primer is generally not needed except on some aluminum. Foam will adhere to the surface layer so if surface is flaking or loose it needs to be addressed. Heat is good but watch for moisture introduced by propane heater. Im not in your climate zone so I dont know your...

Large company is good because they have the finances to eat something like this. Large can also mean they need tons of installers, so you get guys with 3 days or less of training thrown into the field who haven't learned to "read" the foam as its being applied. I can tell you that an...

Glad its getting addressed. Jobs like these are what have given spray foam a bad wrap when a company doesn’t quickly address issues or goes out of business after a bad install. Pressure washing is pretty much industry standard for cleaning and prep of metal before foam.
