A Brief History

The project entails repairing the building at 335 Maplewood Ave in a manner that meets both preservation and sustainability goals. The building is the new location for Petersen Engineering, a firm that has been located in Portsmouth since 1992, and specializes in sustainable building engineering. We intend for this project to showcase techniques & materials that promote both preservation and sustainability and intend to share all aspects of the project locally and regionally through open houses, presentations, industry tradeshows, case studies and publications. We foresee this project being a valuable educational tool to demonstrate that preservation goals need not be compromised by sustainability goals. We have teamed with Bruss Construction who we know from past collaborations has exceptional experience and expertise on projects with the dual goal of preservation and sustainability.

The project received approval by the Historic District Commission on January 6, 2010 with construction scheduled to begin early February 2010.

The projected peak heat loss reduction is 85%.

Siding Install


The Bruss team subcontracted the siding instillation to Deventry Construction. They are fast, efficient and have a lot of guys to get the job done in time for the painter who will be here next week.


The siding we are using was milled in Granville, VT by the Granville Manufacturing company. They have been open since 1857 and specialise in high quality wood products.


The spruce siding was delivered to us a few weeks ago. It came in 6' lengths with 1 coat of primer already applied.

This is how they install the siding:

First they carefully calculate out the vertical reveal distances of the siding so that a full course of siding will rest at the top and bottom of each window (this looks good). The siding reveal distances will fluctuate a few 1/16 of an inch throughout the building in order to make this happen. Don't worry, these little differences are invisible to the naked eye.
Double click on the image below and notice how the reveal distances change as you go up the building and that there is a full course of siding above and below each window. Also notice that at the bottom of the wall, the siding reveal starts out small and gradually gets larger as it goes up. This is a historic detail we wanted to include. Aesthetics aside, building up the siding at the bottom of the wall kicks the bottom edge of the bottom piece of siding out over the skirt board a little bit to help divert water to shed over it and not behind it. Old building all over town have this detail. It looks good and the original siding on this building likely utilized this detail.





These are their "story poles". They have the pre-determined reveal distances marked out on them for the different sections of wall. They hold the story poles up to the corner boards and window trim to mark out where the siding needs to line up on the trim.


See the marks on the corner board...

Once the reveal distances have been established and marked, it is time to start cutting and nailing!


Cut siding to size. (after measuring of course!)


Prime all cut edges.


Pre-drill the nail holes only at the ends so that the wood does not split. (yes... unfortunately it splits)


Hold it up.


Nail it down.


Notice that the Home Slicker does NOT smush when nailed. (The force of the nail is spread out over a large area.)

They are hand nailing because nail guns can be inconsistent in how far they fire the nail into the piece of wood. They sometimes will shoot a nail completely through the siding. We don't want that. These nails are going to be exposed and we want it to look good. Hand nailing is the only other option. It takes a little bit longer but we want it to look good.

That is basically it.

Here are some miscellaneous picture...


One of the ground guys passing some siding up to the guys on the staging. (They typically have 2 guys installing the siding and 2 guys supporting them by cutting pieces to length and bringing it to them)




Notice the full course of trim at the top and bottom of the window... Looks nice huh?




They wedge a little scrap behind the bottom course of siding to give it that extra little kick out.


Notice how the reveal distance get bigger and bigger as you go up?


4 Deventry guys and 2 Bruss guys (installing front door trim so that they can run siding up to it) all working on the same wall at the same time.


They are almost done...
