1940s Ranch Home Receives Remarkable Dutch Colonial Makeover

By GCP. 

Sweenor Builders and This Old House teamed up to transform this home with GCP's waterproofing solutions.  

Sweenor Builders Incorporated has dedicated themselves to building beautiful homes for coastal Rhode Islanders for the last 25 years. The well-renowned and award-winning builders have collaborated with New England’s top architects and since 2017, they have had a partnership with the Emmy Award-winning television show This Old House to remodel unique homes.  

The project  

For its fourth project with This Old House, Sweenor Builders converted a 1940s ranch-style home in Westerly, Rhode Island into a four-bedroom Dutch Colonial with an open floor plan. Formerly a ship-building community, Westerly has many homes like this ranch house that have a plethora of original knotty pine interiors. The new homeowners were keen to give the home a fresh look and layout for their family.  

Sweenor Builders brought building and design expertise to this inventive project, which encompassed adding a second floor, expanding the kitchen and dining room space, raising the ceiling height and adding a deck. To provide a seamless transition, Sweenor’s architectural designer recommended creating a gambrel-style roof on the front and leaving the existing roofline on one side of the house. This gave the appearance that an elegant wing had been added to the main house.  

The challenge 

The firm is known for ensuring the high level of energy efficiency that today’s homeowners expect. 

As with all its construction jobs, Sweenor took great care in waterproofing and sealing the home prior to putting on any finishes. “Most of our work is done near the coast, and we get a lot of wind-driven rain here,” said Sweenor Builders Founder and CEO Jeff Sweenor. “We like water to be well managed.”  

"We like GCP’s self-adhered roofing underlayment and weather barrier products because they seal when you penetrate them" said Jeff Sweenor, Sweenor Builders Founder and CEO. 

The solution 

“Our philosophy is to make sure the home is dry and leak proof before any shingle goes on,” Sweenor said. “We’re all about waterproofing and air sealing. We typically use GRACE ICE & WATER SHIELD® underlayment on the entire roof because it gives us a faster way to get dried in before shingles go on. We like GCP’s self-adhered roofing underlayment and weather barrier products because they seal when you penetrate them.” 

GCP’s VYCOR® enV-S™ weather barrier was also critical to the renovation project. “The original sheathing materials were 2x6s or 2x8s, since people weren’t as conscious about air sealing back when the original home was built,” said Sweenor. “VYCOR® enV-S™ weather barrier are a self-adhered membrane that works well to bridge an imperfect sheathing job so we can provide air sealing for the home. That makes a big difference when it comes to heating and cooling costs.” 

The builder used GCP products based on their long history of performance and their compatibility. “All the GCP tapes and specialty products complement each other and are engineered to adhere to one another,” said Sweenor. “Having a system instead of individual components is beneficial to ensure strong adhesion, and ultimately strong weather protection.” 

"The VYCOR® enV-S™ weather barrier is a self-adhered membrane that works really well to bridge an imperfect sheathing job so we can provide air sealing for the home. That makes a big difference when it comes to heating and cooling costs," said Jeff Sweenor.
