Preparing the site for the new PT deck in Franklin, MA

Here we have the site preparations for a pt (pressure treated) deck underway. The vinyl siding has been removed from the lower portion of the walls to allow for the deck to be properly anchored to the exterior of the house with a pt ledger-board such as the ones lying on the gravel in front of the french-doors in the picture.

Those french-doors, by the way, are a beautiful solid pine 6′ wide series from Andersen. Also notice the black strips below the 2 Andersen doors. Before the doors were installed ice-and-water moisture barrier was applied to the rough openings of the doors, taking care to lay over the Tyvek underlayment to provide maximum protection against moisture and the elements.

Gravel aggregate, a few inches thick, has been spread on the ground under where the deck will sit. Laying down some gravel is particularly important when you are building a deck that will sit close to the ground such as this one will. The layer of gravel aggregate will help in preventing plant growth and moisture build-up underneath the deck.

The 4′ concrete footings that will support the weight of deck will be poured into those yellow sona tubes you see in the ground. Sona tubes are great for giving you a strong consistent structure for your footings. Why 4′ deep? Here in New England you have to get below the frost line with any sort of base-structural support, such as our concrete footings for the deck. Going this deep prevents the footing from shifting and cracking, insuring a long life or your new deck.

Lastly, we have the trench located in front of the main row of sona tubes in the picture. This will provide for the long concrete landing that we will be pouring for the stairs coming off the deck. This customer wanted long steps going the entire length of the deck. It was a lot of concrete for a landing, but it sure did look good when it was done, as you will see.

Finished kitchen remodel & family room addition in Franklin, MA

Here is a photo of the completed kitchen & family area. This is a very open design with the kitchen blending into the family room portion of the addition. The layout makes the kitchen area seem much larger than it really is. And even though the working kitchen is actually not that large, it provides full functionality and a well planned layout with regards to the appliances, sink and food preparation area, sure to satisfy most cooks.

The post and beam in the middle of the picture mark the original back wall of this single family home. We framed the addition and installed the doors and windows before removing the existing walls and replacing them with an engineered Glu-Lam beam and Glu-Lam posts. An arched opening was also added to the mud room portion of the addition on the right side of the image. This was designed and built to match exactly with the existing archway opening on the left side.

Zoned recessed lighting on dimmer switches and a custom, raised, countertop/breakfast-bar section supported by a 2×6 knee-wall assembly and 2 functional corbels complete the look of this nice little addition/kitchen remodel. We enjoyed doing this project and the customer was thrilled with the end result.

Installing unfinished hardwood flooring and framing the raised section of the kitchen island at the Franklin, MA addition.

Here you can see the hardwood flooring partially installed. On this project we were going to be tying our new hardwood floor in with an existing hardwood floor. They met in a wide opening between the new kitchen area and an existing hallway. For this reason we did not go with a pre-finished hardwood flooring product, using unfinished hardwood flooring was the way to go  to achieve the best possible match with the existing floor on this project.

The 2×6 framing you see in the middle of the floor will create the raised section of the island. Corbels will be installed on the back of the finished unit to add additional support for the countertop overhang on the raised section. Two standard base cabinets and countertop sections with a range in the middle will be installed on the facing side of the 2×6 structure.

Garage Addition Framing And Roofing - Bellingham, Ma

This is garage addition we did for a family in Bellingham, Massachusetts. As you can tell the frame is complete and you can see Mike up on the roof applying ice-and-water barrier to the edge of the plywood roof in preparation for asphalt roofing shingles. Ice-and-water acts as a protective barrier for… you guessed it, ice and water. This is especially important here in New England. What can happen during cold winters is that ice can melt from higher areas of the roof and the water will travel down the roof. This water will often refreeze and cause ice-dams on the lower edges of the roof planes(eaves). This barrier will help to protect the roof in case the ice dams are able to penetrate below the shingles. A responsible roofing contractor in the North East will ALWAYS use ice-and-water barrier on the eaves and valleys to add extra weather protection to your home.
