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%.

Top of window flashing!

Just how we left on our 6/15 post....


Fold up Tyvek.


Cut flashing to size.


Fold edges of flashing over sides of window molding.


Gently tap it into shape so that the corners are square.


Tap tap tap...


Lay down bead of caulk.
(If water does get behind the flashing..we do not want it getting behind our trim as well and working its way into our walls.)


Place flashing back ontop of window.


Make it tight.


Even at the edges..


Nail at center...


...and sides


Fold Tyvek down.


Cut back a few inches.


All of it...


Lay down small piece of tape at corner.




Tape angled cuts of Tyvek.






Final piece of tape to hold down flap of Tyvek to flashing.


*clap hands and walk away


...but don't forget to caulk the edge of the trim. (I don't have a picture of this)
