Arlington Arts & Crafts
38–01	"Arts and Crafts Class Begins"	September 29, 2016 (September 29, 2016)
Kevin, Norm, Roger, Richard, and Tommy are back in Arlington—this time at an early English-style Arts and Crafts house built in 1909. Kevin meets the homeowners Nick and Emily, both originally from Arlington, and gets a look at the first floor to see what has been preserved and what has been altered over the years. Meanwhile, Norm goes upstairs to check out the plans for the second and third floors. Outside, Roger and Emily take a walk around the property with landscape architect Kim Turner to discuss how the homeowners envision using the space. Down in the basement, Richard shows Kevin the inefficient boiler and talks about plans for future mechanical and plumbing systems. Back upstairs, homeowner Nick is up for his first task: demolishing the outdated kitchen.
38–02	"A New Look, Inside and Out"	October 6, 2016 (October 6, 2016)
The design process kicks off with a meeting at interior designer Jill Goldberg’s shop in Boston’s South End. Homeowner Emily sorts through colors and wallpaper ideas for the living room to brighten up the house. Back at the house the old plaster walls are carefully demolished. Landscape architect Kim Turner presents her first landscape plan to Nick and Emily outside, and Roger brings in a certified arborist to begin removing the old Silver Maple. Kevin and Tommy bring down the exterior back wall to make room for the new addition.
38–03	"Make Way for the Family Room"	October 13, 2016 (October 13, 2016)
Tommy and Kevin replace a 100-year-old wooden beam with a new steel beam to provide support for the new addition. Norm visits local examples of Arts & Crafts style houses with historian Richard Duffy. The old oil tank gets drained and removed by a specialist. Digging for the new foundation begins and the old concrete pieces from the patio and foundation get transported to a recycling center. Tommy shows Kevin what happens to the material once it is there and how it is used for future construction material.
38–04	"Foundation Fundamentals"	October 20, 2016 (October 20, 2016)
Kevin meets Tommy in the old playroom, looking out over the work on the new foundation. Tommy shows Kevin the ICF’s (insulated concrete forms) that replace traditional foundation molds. They discuss the high efficiency achieved with this system. Then Tommy introduces Kevin to Kent Reusswick, who supervises the installation. Kent’s crew finishes the job and is there when the concrete is poured. Homeowner Emily, joins Roger Cook and Landscape Architect Kim Turner on a shopping trip to find mature specimen trees for the yard. Back at the addition, a precast concrete bulkhead is installed. The old rubble foundation that was exposed during the excavation for the addition needs reinforcement. Mason Mark McCullough erects a concrete wall next to it to keep the house standing for another century. Before backfilling, the old foundation that’s exposed outside gets waterproofed with a synthetic rubber spray.
38–05	"A Steely Den"	October 27, 2016 (October 27, 2016)
Tommy and Kevin take a road trip to see how the steel beams used in our house are fabricated. The beams are trucked to the site and Kevin finds Tommy supervising erection on the back of the house. The third floor has been demo’ed and now Richard can start an HVAC plan for the second floor. He’s looking on the third floor for a location for an air handler and duct work to provide air to the floor below. The front porch must be demo’ed to make way for a new design. With the help of heavy machinery, Tommy’s crew does the job quickly. Then Tommy walks Kevin through the process of placing footings for the new porch. Kevin finds Mark McCullough working on the firebox. Kevin wants to learn the dark art of figuring firebox size and chimney height.
38–06	"One Brick at a Time"	November 3, 2016 (November 3, 2016)
Now that the firebox is installed, it’s time to start the new chimney for the addition. Mark McCullough, expert mason on the project, gets an apprentice for the day—a homeowner. Then he travels to Bridgewater, MA to visit a brick-making factory and gets a tour from the 4th generation owner, Lincoln Andrews. Mark watches how the bricks are mixed, formed, cut, and baked at the 100-year-old factory that provides bricks throughout New England. After several years with a tiny kitchen, Emily and Nick are excited to design the space of their dreams. Kevin meets them at a cabinet shop in the quaint New England city of Bath, Maine, where kitchen designer Heather Krausse reveals her ideas for their project. Back at the house, Kevin finds Tommy up on the roof changing the pitch of the two back dormers to match the pitch of the new gable created by the addition.
38–07	"To Paint or Not to Paint"	November 10, 2016 (November 10, 2016)
The homeowners want a unique look for their kitchen. They think a custom range hood will fill that vision. Kevin visits the shop of Ed Packard, otherwise known as the Tin Man, to find out how the range hood is coming together. The original chimney has seen better days and needed to be demo’ed. Kevin goes up on the roof to watch Mark McCullough build a new one. Nick and Emily need to make some design choices in order to move construction along. Kevin finds Emily and Jill Goldberg, the designer, in the new family room discussing options for the fireplace. They want to somehow hide the television, which will be over the fireplace. Other decisions to make are tile for the first floor powder room and whether to paint the wood panels in the living room. Up on the third floor there’s a small problem that Norm and Charlie Silva need to figure out. All the way down in the basement, both the original floor and new slab floor are being coated with a speckled epoxy.
38–08	"A New Look to Match the Old"	November 17, 2016 (November 17, 2016)
Demo of the old walls for the addition revealed a hidden doorway to the kitchen from the main hall. Norm and Charlie tackle the job of opening up the old entryway. The homeowners have a beautiful design plan for the new master bath, but it presents a classic plumbing problem. Richard shows how the open space below the bath must be traversed by drain and vent pipes. There are several distinctive features that will change the front of the house. The roof on the front porch has a special shape, as do the brackets on the side of the house. To create the elaborate cuts required for these features, Tommy’s team turns to a special shop that creates them with computerized cutting machines. Norm gets a tour of the shop and sees the brackets and porch rafters in the making. Back at the jobsite, electrician Scott Caron gets started with his work in the first floor powder room where he installs a ceiling fan, and gets ready for switches and outlets. The living room had three single-pane windows that did not open. Nick and Emily want to replace them with double-hung windows that fit with the Arts and Crafts style of the house. Today, Tommy and Charlie are putting in new, energy-efficient windows.
38–09	"Arts and Crafts from Top to Bottom"	November 24, 2016 (November 24, 2016)
The project’s old front porch was a hodgepodge design: part permanent, part temporary. Kevin finds Tommy framing the new front porch using custom-cut and assembled rafters. The new design puts an Arts and Crafts punctuation mark on the front of the house. Nick and Emily have chosen special marble from Danby, Vermont, for their countertops. Richard travels to the world’s largest underground quarry, where the stone originated, to find out how marble makes its way from inside the mountain to inside the kitchen. Emily wants the new exterior color of the house to fit in with the Arts and Crafts design. She has brought in preservation specialist Sally Zimmerman to help with the color selection. Norm catches up with them to find out what they have decided. Stucco panels are part of the Arts and Crafts charm of the project house, but they need work. Mark McCullough, in the process of fixing panels, shows Kevin the lost art of stucco.
38–10	"Shedding the Old Look"	December 1, 2016 (December 1, 2016)
Homeowner Emily has always wanted an enclosed space for her yoga and decides that an outdoor shed would be the perfect solution. Kevin meets the foreman of the shed company who will oversee the one-day process. The walls come preassembled and are raised like an old-fashioned barn raising. Tommy comes by at the end to inspect the construction. On the main house, a standing-seam copper roof is installed over the front porch. Kevin and Tommy watch the final pieces go on. Tommy shows Kevin how to trim a window using a PVC product. He shows Kevin his special technique of using a rabbet joint to connect the joints. Down in the basement, Richard watches as plumber Kevin Bilo installs a state-of-the-art boiler. This new system will take a huge bite out of the high heating bill. Next, Richard takes a road trip an hour away to visit a newly built house that uses advanced building techniques and eco-friendly materials to achieve remarkable energy efficiency.
38–11	"Underground Energy"	December 8, 2016 (December 8, 2016)
The homeowners have always wanted to remove a service pole at the front of their property. The electric company has finally given them permission to bury the service from down the street. Today Jimmy McLaughlin’s crew and electrician Scott Caron start the process. At the front of the house, Norm helps Charlie build the flared porch columns. They use computer pre-cut plywood to make the curved shapes. Months of construction work has left the landscape around the house a total disaster. Kevin finds Roger rebuilding the yard starting with laying a new brick patio. First they look at different pattern options, then, once the area is prepped, they start laying out the brick. The kitchen cabinets were fabricated at a shop in Maine. Today they are delivered to the project. Kevin meets the installer, Erik Frey, to watch his one-man process for installation. The architect calls for decorative half timbers and stucco to accent the front gables that were previously shingled. PVC has been chosen for its resiliency. The trick for Tommy is to properly flash the decorative pieces. Kevin helps Tommy with the installation.
38–12	"Changes Start to Show"	January 28, 2017 (January 28, 2017)
The exterior trim detail is complete and now it’s time to shingle the rest of the house. Tommy is using pre-primed red cedar shingles with a 5-inch reveal. Inside, homeowner Emily and interior designer Jill Goldberg meet Donna Boerner, an in-home stylist, who will help them figure out what kind of window treatment works best for each window. Looking at various types of shades, they work their way through the rooms. Down in the basement, it’s time to start installing the radiant floor tubing in the tracks under the existing old floor. In the living room, Mark McCullough repairs the grand fireplace. He repoints the loose bricks and carefully mends the decorative clay mantel using new pieces that were precast from a mold taken from an unbroken part of the mantel. Outside, it’s time to build the back deck coming out the side door. Tommy and Norm frame it up.
38–13	"Decorative Touches Make the Difference"	February 4, 2017 (February 4, 2017)
There are many new decorative elements on the outside of the house - including a small roof detail supported by two brackets on the side of the house. Tommy assembles the roof on the ground first, doubling up the fascia for extra support. After he installs the second bracket, a lift helps to raise the roof into place. Upstairs on the second floor, Emily and painter Rosemary Dewees introduce Kevin to the technique of Lazure painting – a watercolor style of painting interior walls. Using multiple brushes and buckets, Kevin finds that it’s not as easy as it looks. The beautiful front door has seen better days. The homeowners ask master restorer Wayne Towle for help refinishing the oak veneer. Kevin visits his shop to see how it’s done. Downstairs, Tommy installs wood paneling in a corner of the living room that once housed a bookshelf. Even though it’s being painted white, he uses solid oak to match the existing wood grain paneling. Outside, Roger plants screening trees that Emily and landscape architect Kim Turner selected earlier in the season..
38–14	"Shiplap for a Ship Shape House"	February 11, 2017 (February 11, 2017)
Everyone is covering their walls with shiplap. Homeowners Emily and Nick love it too and want to finish their third floor with it. Kevin finds Tommy installing shiplap in Nick’s office. Outside, the landscape plan calls for a walkway from the front porch stairs down to the street. It will consist of brick pavers and granite steps. Kevin helps Roger’s crew lay the second set of steps, using reclaimed granite from a New England bridge site. The marble slabs that we saw being quarried in Vermont have made their way down to the shop of Roberto Martinez. Roberto works with Emily to find the best piece of the slab for the kitchen island and then he goes to work cutting it. Back at the house, Emily makes her final decision on the oak paneling in the living room. Originally, she and Nick wanted to refinish the paneling. Then they decided to paint it white. Now Emily and designer Jill Goldberg meet with painter Mauro Henrique to review the paneling once more after the old finish has been stripped off. In the new family room, mason Mark McCullough builds the cast stone mantel surrounding the new fireplace. The decorative mantel was fabricated in Texas and shipped to the house in pieces. Mark and Kevin put the pieces together.
38–15	"Details Make the House Beautiful"	February 18, 2017 (February 18, 2017)
The journey of the Vermont marble continues from the cave to the counters. Richard watches as fabricator Roberto Martinez and his crew install the largest piece of marble at the kitchen island. Nothing says New England like a fieldstone wall. Kim, our landscape architect, calls for one that starts in the front yard and bends down along the driveway. Kevin finds Roger and his team laying the first giant stones for the wall. There is much more involved than just stacking rocks. Upstairs, Kevin finds Mark Pehrson hanging textured wallpaper over a wall that contains a secret door. What was once the master bedroom closet has now been switched to an upstairs foyer closet, but the homeowners want to cover it with a door that blends with the wall. In the basement, Richard looks at the finished radiant floor heating as well as a new state of the art air conditioning and supplemental heating system. The mechanical room wall is well organized and all hot water pipes, valves and pumps are labeled for the homeowners’ reference. Fresh air ventilation is needed in the super tight space and Richard explains how the system works. Finally, the dog gets her own door as Tommy and Kevin install an extra-large dog door in an exterior wall of the mudroom. Soleil stops by to give it a try.
38–16	"An Arts & Craft for the Ages"	February 25, 2017 (February 25, 2017)
The Arts and Crafts house in Arlington is at completion and the guys come to take a last look and celebrate with the homeowners. Kevin and Tommy arrive at the new entrance where the old Silver Maple tree and telephone pole once stood. Kevin tours the front yard with Roger and landscape architect Kim Turner. Kim points out the new plantings in the front yard and all the hardscape that Roger and his crew have worked hard to finish. Meanwhile Tommy goes around the back to meet Norm and look at the three-story exterior addition. They reflect on how the addition was designed and built to look like it was always there. Inside, Kevin looks at the refurbished front door with homeowner Emily. The foyer ceiling has been covered with an embossed paper made of linseed to give it a decorative feeling. Emily points out other updates and they check out a new stair runner being installed on the front stairs. In the dining room, paneling has been added to the walls and an Arts and Crafts style wallpaper is above it. But the biggest change is the beautiful new oak pantry cabinets that replace what was once the outdated galley kitchen. The cabinets have a pass-through that connects to the dining room so that glassware and dishes can be accessed from both sides. Richard heads upstairs to the second floor and meets homeowner Nick. With the new addition, the entrance to the master bedroom was changed to allow for a suite with two closets, the bedroom, and a spacious new bathroom. Richard looks at the new technology in the bathroom – the shower, bathtub, and toilet all have control panels for a variety of functions. Norm finds Emily putting the finishing touches in her daughter’s room. Not much was changed in there except for a special wall painting style similar to watercolors. They head up to the third floor and look at the new craft/play space that the addition allowed. Originally the idea was to move the third floor

Through a program called Rehabbed & Ready, the city plans to renovate the property and sell it to a family who plans to stay. After the mounds of trash and abandoned belongings are removed from the house, Kevin meets general contractor Tom Abbott and lead contractor Darrick Scruggs, who will manage the renovation. Back at the Russell Woods project, Scott Caron meets Wes Kasperski, who is installing an alarm system to keep the house protected during renovation.

After removing it all, they use a rubber roofing material to properly seal the roof and prevent further leaks. Kevin heads to nearby Dearborn to tour the sprawling estate of a famous automaker. After decades of wear and tear by various owners, the mansion is finally getting a much deserved makeover, using preservation techniques to preserve the history throughout the home. Back at the house, Kevin and Tommy work with Frank and his friends to demo the kitchen walls and investigate whether a beam is needed to open up the room.
