Spray Foam Insulation in Murphy, TX

Spray Foam Insulation in Murphy usually means upgrading houses that are now twenty-odd years old. Murphy had 1,126 housing units in 2000 and 6,083 in 2020, almost all inside a 5.7-square-mile city. The growth followed the President George Bush Turnpike, which opened in 1999. Population rose from 3,099 to 21,013 over the same twenty years.

Built before the statewide minimum

Many Murphy homes went up in the early and mid-2000s. Texas adopted the 2015 IRC energy chapter statewide on September 1, 2016, with R-38 ceilings for Zone 3, so houses from before then were not built to that minimum. Twenty years of settling, attic traffic from cable and HVAC work, and the occasional roof leak take their toll on what was installed. A top-up with proper sealing is often all a Murphy attic needs.

Common layouts

Two-story homes with the air handler in the attic, rooms over the garage and long duct runs are common here. Those rooms are the hardest to keep comfortable. Closed-cell foam on the garage ceiling below a bonus room, better kneewall insulation and sealed duct boots are typical fixes; for big comfort problems, foam on the roof deck is priced alongside.

A compact city

Murphy sits in southern Collin County on FM 544 between Plano and Wylie, at about 581 feet. The city maintains 10 parks totaling 195.5 acres, including the 60-acre Murphy Central Park. It is a short drive from McKinney, so scheduling an estimate is easy.

What a top-up costs

For a Murphy home with settled insulation and no serious damage, the job is usually sealing plus blown-in. HomeGuide's national figures put blown-in attic insulation at $0.90 to $2.40 per square foot and an average attic job at about $1,800. If the insulation is dirty or contaminated from years of service work or pests, removal adds HomeAdvisor's $1 to $2 per square foot. We list each of those on the quote so you can see where the money goes.
