Difeo Construction and Property Management describes itself as a family-owned contractor in New Hampshire's White Mountains, operating for over 25 years and offering contracting, renovations, development and property management. It names Conway, Jackson, Bartlett, Madison and Albany as its service area. A recent customer said John and his company completely gutted and remodeled a small chalet of original 1970s construction, with John coordinating the subcontractors and doing a lot of the work himself. A recent reviewer described a new deck, siding and windows from Difeo Construction and called the crew responsive and easy to work with. New windows, siding and outside lighting came from John Jr and his team, according to a recent customer. In a 2025 review, a customer said John Sr. and John Jr. renovated their A-Frame after a large pine tree fell on the house during a storm, from the initial estimates through working with the insurance company. That 2025 customer listed roof repairs, a new front deck, an under-deck patio, updated electrical, deck drainage and fresh painting. A 2025 customer said the company handled a full kitchen demo and renovation and kept the workspace clean during the demolition.
Went with John and his company to completely gut and remodel my small Chalet as it was original 1970s construction and was overdue for much needed upgrades. John and his crew did a great job in all aspects of the remodel. He was able to coordinate and take out the headache of getting the right sub contractors as well as doing a lot of the work himself. Overall we are happy with the final product that was handed over to us.
We couldn't be happier with the work Difeo Construction did on our home. Our new deck, siding, and windows look fantastic. The crew was responsive and easy to work with throughout the project. The quality of the workmanship was excellent. I would definitely recommend them!
Had a great experience from start to finish, now feel like we have a brand new home, new windows, siding and outside lighting. Couldn’t be happier with John Jr and his team, very professional.
I recently hired Difeo Construction & Property Management for a full kitchen demo and renovation, and I couldn’t be happier with the results. From start to finish, the team was professional, efficient, and incredibly detail-oriented. They handled the demolition with care, keeping the workspace clean and minimizing disruption in my home. Couldn't recommend them enough.
John Sr. and John Jr. did an amazing job on a complex renovation of our A-Frame after a large pine tree fell on the house during a storm. From the initial estimates, to working with our insurance company, to guiding us through potential upgrades, they were professional, responsive, and great to work with. The project included roof repairs, a new front deck, under-deck patio, updated electrical, deck drainage, and fresh painting. I would not hesitate to call Diefo for any project!
