My builder uses Houzz Pro to plan the timeline and give detailed estimates and daily updates with photos of progress, and provide invoices at pre-agreed key points in the build. This made the whole experience much more efficient and stress-free.

New Line Carpentry, LLC
Home Addition & Extension Contractors Near Rockville
Average rating: 5 out of 5 starsNovember 14, 2025
“New Line Carpentry did a wonderful job. My greenhouse floor gave way right before winter weather set in.They quickly reframed the floor and even helped protect my plants during the construction. Clean, courteous, reasonably priced, fast and conscientious. Thanks so much for a job well done. Definitely recommend. Would absolutely hire again.”

Average rating: 5 out of 5 starsMay 12, 2025
“I had the pleasure of meeting Kurt during a tour of our Net Zero Energy Building in Washington, D.C., and was impressed by his enthusiasm for sustainable living. After learning about his ICF-insulated home and use of ground-source heating, it's clear he's deeply committed to energy-efficient design. It's always inspiring to connect with others who are walking the talk when it comes to sustainability. Keep up the great work!”
Mitchell & Best Homes
Home Addition & Extension Contractors Near Rockville
Average rating: 5 out of 5 starsFebruary 14, 2023
“After looking to move from Montgomery to Howard County for a few years, we stumbled upon a lot down the road from Maple Lawn that was beautiful and quiet. We thought we were going to look at a pre-existing home only to find a small neighborhood with empty lots. Having no desire to go through the new construction process, we reluctantly agreed to visit the model home Mitchell and Best had in Maple Lawn. We were so impressed with the build quality and their reputation that we decided to have Mitchell and Best build our home. Driving by daily to see the progress, it would not be unusual to see the foreman staying late by himself going over minute details. We were VERY impressed with the quality control. The quality of materials exceeded those of their competitors. Mitchell and Best worked with us to have a few changes made in design that we wanted. Post construction, we had a few minor issues which Mitchell and Best addressed without reservation. Having owned and known people who do own them, Mitchell and Best was superior in quality and construction when compared to Stanley Martin, Toll Brothers, NV and Ryan in our opinion. Mitchell and Best are more custom built homes than most of their competitors and it shows. We are very thankful we chose them to build our beautiful home.”
