About
With 20 years experience; I’m a working owner; present during installs making sure the projects go as planned. If you value quality, service and craftsmanship over price; then we are the company for you. I use CAD drawings to help design your project, allowing you to envision it before its built. I then use that same drawing to give blue prints to my installers so they build the project to the exact specifications we agreed on. We offer Financing on all projects.

Josh was great to work with and had excellent suggestions to steer our design. The work crew was top notch and completed our project in just two days. We are very pleased with our landing and stairs!

Can’t say enough good things about DiffanDud services. He rescued me when another thumbtack contractor scammed me out of my $8000 deposit. He designed a much nicer screened porch than I envisioned, using quality materials on everything. His workers were friendly, skilled and hard working. I am extremely happy with my new outdoor space.

Josh came out to give me a quote for a new deck. He let me know when he was going to be here and was right on time. He asked good questions, and worked with me to put together an estimate in about fifteen minutes after our discussion. Very helpful.

Josh and his team did a great job building my new deck. Josh worked with me on a price that fit my budget and ensured that the permit process went smoothly. I would highly recommend Diffandud Services!

Josh is a true professional with an extraordinary commitment to quality work, creative eye to design solutions, and solid communication from beginning to end of project. We are so pleased with how seamless our screened in porch blends in with the design of our home - it looks like it is part of original design. We would absolutely work with Josh again for future projects and his crew did an amazing job performing the work and cleaning up.
