If you look for people who are reliable because they understand your needs, affordable, and really competent, CWS is what you need and look for. I have interacted with Denis about a roof repair following to a chimney removal. I was able to discuss with him during the evening, he organized an intervention the following day before an heavy rain. He asked me the good questions in order to provide me the best solution. He did not only fix what I asked, but he also fixed additional discrepancies..... at an affordable price, and always with a smile and willingness to help me, really.
I will call him for any suggestions in the future, and I recommend CWS to anybody.
