Cordell were helpful with planning the installation throughout the long lead in period. When the day arrived for the installation to take place the crew were prompt, easy to work with and efficient. The project was completed well under the time budgeted and everything was left working properly .The engineers provided training in how to use the newly installed equipment. They went over everything twice and there was no rushing to finish and leave the site. The engineers cleaned the area thoroughly afterwards and checked that we were happy with the completed installation. I heard about Cordell from a satisfied neighbour and I ,in turn , have no hesitation in recommending the firm ,they provide a good product at a good price.
