    I just had a wrap around deck installed with a pergola & Endless Construction did a fantastic job. They showed up when they said they would. Cleaned up after themselves & were always courteous while on the job. I would highly recommend them.

    Siding
    $3,500

    They do work without permits and not up to code cutting corners. Then they bring in other people that don’t even work there to do their work then those people come to our home for money that evidently they were told by endless that we would pay them . Also they start job got a deposit and put siding on half of our home then left our house open to weather for months unfinished caused rain to get inside our house. The work that was done was shoddy and had to be redone. Please save yourself the trouble!

    My experience with them was horrible. My home does not appear under the work probably because they never finished (Legal issue and now with DLLR.) Poor oversight while they were on the job. I am sure they ran into cost overruns because the General contractor (Jaime Martz) made guest appearances on the job over the more than a year of the project then decided he had enough. My mother's house is one of those listed also (we hired them almost at the same time, Her experience with them was just as bad. Unfortunately, they are shysters. I am paying for it with construction issues, electrical issues, plumbing issues and HVAC issues. The house does LOOK nice though. Dont do it.
