I learned this trade on the crews of a big commercial insulation company, spraying foam and fitting board in warehouses, schools and office buildings. That's where I saw that most insulation problems trace back to a step someone rushed. I started Sealcraft Durham Insulation Company here in 2013, and 13 years on, I still come out to look at the job and write the estimate myself.
Our trained installers do the work, with a crew lead on site. We're licensed and insured. If you're comparing bidders on a spray foam job, the usual hiring advice is to check the crew's training, insurance and licenses, and to check references. Ask us those questions the same way you'd ask anyone else. Satisfaction guaranteed.
I'd rather lose a job by being straight with you than win it by skipping a step. If you want someone to explain what's going on in your building before anyone touches it, call (919) 246-8605 or send us the form, and I'll set up a time to come look.
