Addition Builders In Your Area

Expanding your house is a major undertaking. Not only are you altering your existing exterior walls, you are most likely adding new electricity, foundation, and plumbing. Even planning a room addition needs a lot of groundwork before construction begins.

  • Make the best use of your existing floor plan and supports.
  • Build the new electrical connections and plumbing to code.
  • Incorporate the existing foundation for better stability and reduced settling.
  • Register the addition with your county according to local regulations.

"Of the three vendors that gave us quote, Cyrus, the US Builders owner, was the only one who actually had a vision for our bathroom. If was awesome to come home and see how much they were able to accomplish on a daily basis. Cyrus kept us informed what would be happening each day and did everything he said he would do on time and within budget. We liked his work and customer service so much we gave him a second project to remodel our powder room. We definitely plan to use US Builders again when we move to our next house. "

"We hired Kozan Construction to do some major plumbing construction work moving the plumbing for a washing machine and utility sink and reworking the plumbing for a bathroom sink. They provided a fair bid and so we hired them and were told the project would take a week. Faruk was respectful and hard-working and would accommodate all of our requests to have pipes or the levers moved and straightened. Our main issue was scheduling, as he had a number of other plumbing emergencies that delayed our project and left us without laundry for two weeks. The work was good and done all up to code, so if you have some flexibility with your timeframe, or it s a emergency call then I definitely recommend. If not, just make sure you work out a schedule ahead of time so you know what to expect. "
