Unsellable Houses - Season 4

Lyndsay and Leslie face a difficult buyer's market at a 1960s house with melted tiles, a "murder" floor stain and a teeny shower. The twins create an organic modern masterpiece, but selling this home is the most difficult they've faced to date.

After seven months on the market, Lyndsay and Leslie battle plumbing problems and water damage to get a small home sold. Using unique solutions, the twins transform the crowded entrance, tiny bathroom and rotted deck into a tranquil hideaway.

A homeowner needs help letting go of her home of 25 years, and it has almost as many paint colors. The renovation is a real challenge for Lyndsay and Leslie as they look to transform the color cacophony and convoluted layout into a clean and simple oasis.

Lyndsay and Leslie undertake a 1950s rambler with a rough exterior and an old bomb shelter in the backyard. The twins discover, however, that the home's proximity to a new sewer system triggers a series of problems that only continue to worsen.

After discovering a failing septic system, Lyndsay and Leslie are stuck with a home they can't sell until the county approves costly plans. With no end in sight, the twins look to turn a historic ballroom to its former glory with modern elements.

Lyndsay and Leslie take on a small Snohomish property with two houses and create a distinct style for each. And while untangling an expensive plumbing mess, the pressure goes up when they're asked to throw out the first pitch for the Seattle Mariners.

Two sisters are tasked with selling their parents' previous home and look to increase its value with some updates. Lyndsay and Leslie step in with another pair of twins, Bryce and Colby, to help renovate and mentor them in the ways of twinning.

A realtor tries big price drops on a property, but they still can't sell. Lyndsay and Leslie step in and look to turn their "grandma chic" midcentury rambler from gray and peach into a true retro prize, and they're using their best tricks to do it.

A chance meeting leads Lyndsay and Leslie to a pet damaged home where they turn a patchwork place of unfinished projects into a boho ranch stunner. The twins focus on a kitchen redesign and curb appeal, and one sister can't resist a new puppy of her own!

Lyndsay and Leslie return to their hometown of Mukilteo to help a retired Navy commander and his wife update their home. With a sunken living room, a cramped kitchen and a vanity sink in the middle of the main bedroom, the twins face big obstacles.

A couple looks to lead a simpler life in their new townhome, but first they need to sell their dated house with an uncommon layout. Lyndsay and Leslie take on the '80s style kitchen and bathroom and tackle the makeover with an inexpensive farmhouse style.

Lyndsay and Leslie help siblings who want to realize their late father's grand vision for his '70s Woodinville home. Plans to reroute walls come up against some hefty price tags, however, and the twins determine that they may run drastically over budget.
